When I set off again, there was no group of flies following me, and I felt much more relaxed.

There are still many killers and Baru Demons I saw along the way, but they cannot cause trouble to Chen Bin and the others.

Because if there was a great devil in front of him, Chen Bin and Murphytus could sense it after dozens of miles away, and then bypassed it from afar. In Chen Bin's words, the stench on these guys could be smelled even if they were a hundred miles away.

As long as the killers enter Marisa's kilometer, they will immediately behave like little sheep and will not attack them actively.

Along the way, Marisa took the destroyed killers as test items and dissected them on the spot, revealing the nature of the killers to everyone.

The body of the Killer's metal armor is a semi-mechanical and half-muscle living organism, steel pipes, cables and flesh, which are gathered together to grow. In fact, the metal armor is their skin, but what flows in their metal blood vessels is not blood, but thick black substance, which is scattered with a strong smell of engine oil and rotten smell.

Observing this substance close-up, Chen Bin suddenly remembered what this substance was. When he was outside the Yongcheng Experimental Base, he had seen something similar and almost suffered a great loss - mutated gasoline

That's right, it's after being infected by the j virus and mutated gasoline

Later, Ling Yuexuan also conducted special research on it. The reason why mutated gasoline is active is that gasoline belongs to energy bodies. All organic energy bodies can become food for j viruses. These j viruses mutate during the process of eating gasoline and grow into a normal form of black mold. This black mold has very strong fusion and shaping properties, and these black molds can fuse themselves, which becomes extremely terrifying when forming a ball.

Moreover, this black mold inherits the characteristics of gasoline - low ignition point and long burning time

The burning of the black mold on the outer layer does not affect the black mold on the inner layer, and still does not affect their movement. This is why the fireballs that Chen Chenbin and the others encountered became larger and larger. That is why the black mold is gathering more and more

However, Ling Yuexuan's experiment also proved that this black mold is just a single-celled animal. Even if it is combined together, it is still a group of single-celled animals. Without the ability to think, he can only act on his instinct.

The black liquid flowing in the killer's body also has a similar existence. The only difference is that these molds are produced by J viruses when they eat oil. The composition of oil is much more complex than gasoline, and the mold varieties produced are also much higher than gasoline. The color is rich, just like asphalt in a boiling state, which is very viscous but will not turn into solid. The most obvious of them is their fusion and shaping properties, which actually combine organic matter and inorganic matter to form a special living body.

Compared with their close relatives who have turned from gasoline, their melting point has become quite high. Ordinary flames cannot ignite them at all. However, the energy released after being ignited is quite terrifying. The same amount of the power is one thousand times that of the same amount of TNT. The so-called self-destruction program in the killer's body is an automatic ignition device that can ignite the blood-like petroleum mold in its body. The body of a yellow tracker contains about 40 kilograms of petroleum mold. The body of a huge hunter, guardian, and suppressor has a lot of petroleum mold in its body. That is to say, the power generated by a yellow tracker's self-destruction is equivalent to the power of a 40-ton equivalent TNT bomb explosion. What is this concept? It is comparable to a large missile and is enough to level a mountain.

When they got the conversion value, everyone took a breath and was frightened. Fortunately, they had Marisa. If the yellow tracker had really caused self-destruction and caught off guard, even Chen Bin and Murphytus would not escape death.

What is terrible is that after these petroleum molds enter a mature state, they no longer feed on oil, but feed on high-level energy crystals. For example, essence cores, they can draw energy from essence cores and evolve themselves, so that petroleum molds can condense into tightness and have strong activity. After the petroleum molds gather to a certain level, as long as the energy is sufficient, they can split and reproduce themselves. In other words, there are two generations of petroleum molds. One is the first generation of petroleum molds produced by the j virus feeding oil. The second is the first generation of petroleum molds absorbed enough energy and split into the second generation of petroleum molds.

Relatively speaking, second-generation petroleum mold is easier to generate than first-generation petroleum mold. As long as sufficient energy is provided to mature bodies, the split second-generation petroleum mold is a replica of first-generation petroleum mold. The two are exactly the same. That is to say, second-generation petroleum mold is a mature body as soon as it is born. As long as energy is replenished, it will enter the second fission. At this time, the third-generation petroleum mold is produced, but there is basically no big difference between third-generation petroleum mold and second-generation.

In addition to taking a long time to generate the first generation of petroleum mold, it also has to eat a lot of oil to become a mature body that can split the second generation of petroleum mold.

Of course, the residual ability of petroleum mold to split is not infinite. Generally, a generation of petroleum mold can only split between twenty and twenty-five times. After the last division is completed, petroleum mold will die and become a complete high-level energy substance. It can be absorbed by other generations of petroleum mold and produce qualitative changes. The melting point of petroleum mold that fuses dead petroleum mold will become higher, have strong vitality, and the greater the power it releases during explosion.

The division cycle of petroleum mold requires sufficient energy supply to determine whether the energy is provided. Generally speaking, as long as there is sufficient energy, petroleum mold can complete a lifetime of division in just a few minutes. If the energy is insufficient, their activity can be maintained for decades.

Don't underestimate the division ability of a generation of petroleum mold. Its division form is calculated in the form of a secondary square. One generation splits into two generations. Two generations splits into three generations and becomes four. And so on. By the time it splits to the 20th to the 25th generation, a generation of petroleum mold can split at least between 500,000 and 15 million. This number is quite terrifying. A mold that cannot be seen in the naked eye is already as big as a fist.

Petroleum mold is the energy source of the killer. Petroleum mold can not only convert other solid energy into the killer's own ammunition and power, but at the necessary moment, it can provide energy to the killer at the cost of destroying itself. When burning petroleum mold as energy, the killer is the most terrifying. Whether the bullets shot or the kinetic energy of the fire will become extremely terrifying, because it has been said before that after the death of the oil mold, it is a thousand times stronger than the TNT, and its power of instant explosion is naturally extremely terrifying.

Of course, this state is limited by time, because the petroleum mold in the killer's body is limited, and its importance to the killer is just like the importance of blood to humans. Appropriate consumption can promote the proliferation of petroleum mold. If it is consumed excessively, it will lead to serious loss of kinetic energy of the killer. If it is less than a certain amount, it will directly lose kinetic energy or the shell is seriously damaged, which means that the killer has died

After all, the killer is not an ordinary living body and will not die. As long as his body is re-repaired, a sufficient amount of petroleum mold is injected into the blood vessels of the steel pipe, and it will naturally be resurrected again.

Therefore, the strength of the killer is not constant. The strength between each other is different even for the same model.

The strength of the killer is related to the number of petroleum molds, mature algebras and death algebras, but the size of the killer is fixed, and the number of petroleum molds that can be accommodated in the body is limited. When the upper limit of the accommodation is reached, the rest will only be related to the mature algebra and death algebra.

Mature algebra refers to the algebra of the division of petroleum mold in its body. Every time the petroleum mold splits, the upper saturation limit will increase, and the stronger it will be. In the last generation, it is also the most powerful time in their life. When all the petroleum mold in the killer's body is close to the last generation, its strength is also close to its peak state.

Death algebra involves the characteristics of petroleum mold. It was said before that after the death of petroleum mold, a high-level energy substance will be produced, which can be fused with other generations of petroleum molds to produce higher-level petroleum molds. It can not only fuse with the first generation of petroleum molds, but it can also fuse with the last generation of petroleum molds, but it has the highest compatibility with the first-order petroleum molds and can maximize the benefits. If there is a generation of petroleum mold, it will give priority to fuse with the first generation of petroleum molds. Let's call it a first-generation petroleum mold. This kind of strengthened petroleum mold is even more powerful than the last generation of petroleum molds that have not been strengthened. A first-generation petroleum mold will be like ordinary petroleum molds.

Like a bacteria, it enters the mature reproduction period, constantly absorbs energy and reproduces until death. The energy substances produced by its death are naturally more advanced than those produced by the energy substances produced by the death of petroleum mold. The enhanced energy substances produced by the fusion of the first generation of petroleum mold is called the secondary strengthened petroleum mold. It is not surprising that this time is strong, and so on, it ends with death and starts with death. Every time the petroleum mold in the killer's body is replaced, it will become powerful. Of course, the premise of all this is energy. Only with sufficient energy can petroleum mold be fission-breeding. Moreover, the more times the petroleum mold is strengthened, the more energy is needed for division.

In the final analysis, if the killer wants to become stronger, then absorb enough energy first. This is also the reason why they hunt creatures everywhere. This is their own desire to become stronger. Another reason is that the killer created needs fresh flesh and blood.

In addition to the above, there is another crucial point in the killer - the central control board

This central control board is like the brain of the killer, controlling their every move. Without this central control board, even if the killer is big, he will be a completely single-celled creature.

Because petroleum mold has neither a nervous system nor a tactile system nor a thinking system, no matter how many of the gatherings are, it can only be called a group of single-celled organisms

This central control board should be installed on Marisa's main brain to facilitate control of them.

Marisa was amazed by the clever design of the central control board, which was a perfect combination of biotechnology and electromagnetic wave technology.

The owner behind the killer can use electromagnetic waves to convert them into information that petroleum mold can understand through the central control board, affecting their every move, thereby achieving the purpose of controlling them.

Marisa controls the killer to use this, using electromagnetic interference to interrupt the signal output of the main brain, and she replaces it.

However, the master brain behind this is quite powerful. As long as the connection between him and the killer is interrupted, he can immediately sense it. His attention will be transferred immediately. Under concentrated attack, Marisa can only retreat three feet away. In electromagnetic application technology, the two are not of the same level. Marisa can take advantage of her when she is not prepared, and she won't be able to fight head-on.

The more this happens, Marissa is more curious about what the master brain behind the Slayer exists.

In fact, it's not just her, Chen Bin is very interested in the maker of the slaughter, because he thought of a possibility - that is, whether these slaughtermen can be used by themselves. If he has such a slaughter army, no matter whether you are the king of purgatory or not, as long as you lie down on the earth, if you really can't do it, you will get a bunch of slaughtermen to explode the warriors and blow him to death.

So, when Marisa proposed to visit the mastermind behind the Slayer, Chen Bin raised her hands to agree

The killer's nest is a very simple thing. Chen Bin and his party only took two hours to get to the door, and they didn't even go any detour.

It’s not that Marisa could sense the location of the master’s brain. Marisa didn’t have this ability yet, but they just found a blue collector full of corpses and followed it secretly. It took Chen Bin and the others to the killer’s nest on its own.

After arriving at the destination, everyone was shocked and couldn't shut up.

They felt like they had entered a whole country - giant steel city, giant steel buildings

The giant oil wells are in their working state, but the ones operating them are no longer humans, but killers with green paint sprayed on them. The bodies and yellow trackers of these killers are no longer weapons, but metal tools. It is obvious that they are not killers, but producers. This is a complete killer model-green manufacturer

Oil wells in production

A line of oil gas tanks

Pipe fittings, cable processing plants

A mountain of flesh and blood cutting factory

Steel forging factory with rolling black smoke

Various types of killers are constantly coming out of it. This whole is a killer production line. Apart from the production line, there are no other good words to describe it.

The blue collectors drove in from all directions. Their materials collected were not only limited to various corpses and destruction killers, but also wrapped in various metal products.

In fact, in this steel base, the killers are not limited to the types that Chen Bin and others have seen before, but also many strange killers, such as killers similar to large spiders, and killers similar to large cranes. All of these killers are sprayed with green paint, showing that they are also one of the green makers, but they are just a bit weird.

Here, everyone suspected that they had entered the country of science fiction robots

Everything is in order, without any noise, only heavy footsteps and mechanical creaking work

There were many killers of all kinds, but there was no trace of people, not half of them. To be precise, Chen Bin did not feel any soul breath here, and the whole was a cold, lifeless steel city.

"What about their makers? Are there no makers? They are producing themselves? Impossible, they are spiritually unintelligent creatures without souls, and they cannot have to build such high-tech production lines." Chen Bin asked in a low voice, and soon rejected himself. His words were filled with extreme incredibility. Now they are using Murphytus' group stealth technique to be in the air above the steel city

"Where are their makers?" Marissa pointed to the tower at the center of the Killer's building base, adding, "To be precise, the master's brain is there."

The tower is the most eye-catching building in the entire steel city because it is the tallest. This conical building resembles a signal tower, with a footprint of more than 200 meters. It is straight and straight into the sky. The black and thick chimney of the steel forging factory does not even have half of its size.

The tower is made of steel brackets from fifty meters upwards, and the tower is made of steel downwards purely welded. It is a huge circular building with only a door on the front, and the surroundings are all sealed, and there is not even a window.

Suddenly, a huge red searchlight lit up on the tower, like a huge eye with a strange red light, turning his head to shine on the invisible place of Chen Bin and the others.

"Huh" Murphytus opened his mouth wide in surprise. The red light emitted by the red searchlight actually had the special ability to break the invisibility technique. Now the group invisibility technique she had previously used on everyone has been broken.

"A friend is coming from afar, but since the guests are here, why not come in and sit?" An electronically synthesized neutral sound rang in the air. The sound was obviously not very big, but it was very clear, just like the owner of the sound was talking in their ears.

Swish... As soon as the neutral sound fell, countless killers rose up in the air, surrounding Chen Bin and the others. The number was no less than ten thousand

Chen Bin's face suddenly turned dark and he said coldly, "Do I still have the right to say no?"

"It seems not, haha..." The neutral voice laughed in an unknown way, "What? Don't you want to come in and sit? This is what you came to your door by yourself, not me who invited me."

Everyone looked at each other. They really hit the gun and couldn't blame others. Now they had no other way but to obey the orders of neutral voices, because they could not fight out of this terrifying army of killers.
