Time passed day by day, Yu Hong continued to adjust and test, imitating the formation symbols he drew, and trying to strengthen it with the black seal. Finally, on the fifteenth day, he got the feedback that the black seal allowed successful strengthening. Fifteen days In two weeks, his inner energy has also reached the sixth level of the third level of Thunder Kick. The progress is much faster than before.

During this period, apart from strengthening the nutritional cream once more, Heiyin did nothing else and cooperated with Yu Hong in experiments throughout the process.

Taking advantage of the characteristics of the Black Seal that can only be strengthened when the basics are complete, Yu Hong continued to adjust the simulated symbol patterns until he simulated and copied a piece of symbol details from the new Wind and Fire Spirit Slayer Formation, and finally got the Black Seal's approval. A The complete, basic air flow obstruction formation is obtained.

Inside the cave.

Yu Hong looked at the hand-drawn formation in front of him and wiped the sweat from his forehead. It was a very labor-intensive thing to concentrate on drawing and it required consuming inner energy. But fortunately, there are ready-made formations to learn, little by little. Added tests and finally made a complete version.

This version is definitely not the most concise, but if the basic functions are met, it is enough to enhance the black seal.

He sat cross-legged on the basement floor, looking at the formation patterns on the wooden board. Suddenly his heart moved slightly, and he took out the two trophies he had obtained previously from the wooden frame in the corner. One was a ruby-like crystal from the mutated crow.

The other is the black jade bone from Su Ren's body.

Anyway, there is no trick. The strengthening principle of Black Seal is to use synthesis instead of multiple strengthening... Only by adding new things every time can it be strengthened twice. In this case, just add these two tests... He doesn't I know what these two things are used for. Anyway, just rely on the black seal to control the direction.

Putting the two things on the wooden board, Yu Hong picked them up together, walked out of the cave, and came to the inner courtyard against the wall. Bang.

He put the wooden board on the ground and didn't care if there was anyone around. Anyway, no one else could see the black mark and the countdown to strengthening.

He stretched out his hand and pressed it on the ground. His actions at this time were like checking the quality of the soil on the ground.

The pyroxene grass on the ground in the inner courtyard has long since withered, and now there is a patch of transplanted green wild vegetables. However, the sunlight is getting shorter and shorter. I don’t know how long these wild vegetables can last. Yu Hong pressed his hand on the ground.

Strengthening of the Black Wind Slowing Array, direction: integrating the deceleration array and two other black disaster materials. Strengthening the hindering and slowing effect on the black disaster." He strengthened this time by combining the large array with the array board drawn by himself, as well as two leftovers, all included together.

In order to reduce construction, Yu Hong directly let the black seal be strengthened. Although it takes more time, it does not have to dig out the foundation and restore it again, which saves time. The most important thing is that the strengthening is only underground, and there is no need to worry about being blocked. People find something unusual.

In fact, it is okay to continue to strengthen this function for the Black Wind Protection Array, but the current array is too big, and the enhancement will definitely take a lot of time. I strengthened the deceleration array alone, which should take less time, and I can also use the deceleration that I researched alone. The formation is applied to other places.『

This was the path that Yu Hong had envisioned from the beginning, to learn new things from the enhanced products, and after understanding them himself, add new things, strengthen them again, and improve the camp step by step. This is true for the internal energy, and it is also true for the formation now.

Soon Heyin gave feedback.

The countdown time appears: 17:01.

Yu Hong breathed a sigh of relief, knowing that his guess was correct. It would not take much time to simply strengthen one function. He stood up, took the slow-down formation board with him, and began to think about the combination of various formation symbols.

The symbols he now masters include pyroxene formations, vortex formations, hidden symbols, and now the deceleration formation. In the basement, Yu Hong looked at these four symbols on the paper and already had an idea in his mind.

Why was he wasting so much time? He was willing to leave the black seal alone instead of strengthening things, and he also wanted to cooperate with his own testing and draw a complete deceleration talisman array bit by bit, just for this moment. These four talismans can already form a simple The composite formation...

Yu Hong thought in his mind.

The pyroxene runes are essentially strengthening, strengthening the effectiveness of the pyroxene itself. So it should be called strengthened runes.

The vortex itself is to store and release, and concealment is to hide the breath, reduce and stabilize the radiation activity, which can be used as a safety valve.

The final deceleration can be used to control the energy flow rate, and then combine it with the internal air to draw the pyroxene powder as a connecting transmission line. "In this way, a basic self-created composite array structure is ready."

Yu Hong was excited. As long as a basic composite structure was completed, it meant that nesting could be repeated repeatedly. Looking at the four runes, he began to think about which direction he should try first.

After a while, he decided to do the deceleration formation first.

Using the vortex talisman array as the energy source, it absorbs and releases energy, and then uses it to target deceleration. Finally, the talisman array is hidden to stabilize the structure, eliminate breath fluctuations, and strengthen the talisman patterns to enhance the functional deceleration effect. Yu Hong simply tried the following four talisman patterns. Draw it on a board, connect it with simple Dahui graphite powder, and combine it in sequence.

With the help of the ready-made simulated structure of the Wind and Fire Spirit Slaughter Array, soon... more than an hour later.

A brand new formation board appeared in front of him.

The wooden board is the size of a washbasin. As soon as it is painted, it begins to quickly absorb the surrounding red value, which is stored and used as energy. In addition, Yu Hong also made a structure that can be folded and opened, which can save toner.

Then, it's just waiting...

Satisfied, he put down the board and went to the first floor, ready to eat something.

"If this time is successful, then I can completely use the combination of array patterns to strengthen other functions... For example, strengthen the two corrosive abilities of black wind and black fire in the wind and fire spirit-slaying array! Yu Hong tasted the benefits , I feel like I finally found the correct way to open the black seal.

By studying and absorbing the strengthened things, summing up experience and inspiration, and adding a few new things, you can once again strengthen new and stronger things.

In this way, I will master more and more abilities, become more and more flexible, and can cope with many complex environments, and the things strengthened by the black seal will become stronger and stronger, a virtuous circle. It is like summarizing my own inner strength based on the strengthened skills. Qi foundation, and then directly strengthened the internal power Wuji Qi Condensation Art, which in turn accelerated the Thunder Kick Technique. Time passed slowly.

The sky gradually became brighter, the night passed, and the only two hours of daylight in the day came, and silence came. Yu Hong stayed up all night, trying various combinations of rune patterns.

At dawn, he drank some water and lay down to rest for a while. Inside the stone castle.

Lao Li and Lao Zhou got up one after another and started to prepare for the new day, moisturizing the breeding box, checking the temperature, replenishing humus soil, sorting cockroach and lizard feces, etc. At the same time, they also had to exercise and prepare breakfast.

As combatants besides Yu Hong, Lao Li and Lao Zhou had to practice fighting skills and simulated shooting every day. The two discussed the types of black disasters encountered outside and how to best deal with them.

Just when everyone is going about their daily lives.

Outside the camp, a group of black insects flew together and condensed into a black human shape. It was the Insect Man.

It moved forward mechanically, brushing against the edge of the camp. The distance was getting closer and closer. Poof.

Soon, in the corner, a black lizard spit out saliva and stuck to the side of its cheek.

But this time, the tried and tested spitting and humiliating attack did not cause any movement from the insect man. It remained motionless and continued to move forward.

Walk slowly towards the corner of the camp. Inside the cave.

Yu Hong sat up and looked at the insect man through the black lizard. He did not go out hastily, so as not to arouse the other party's desire to attack.

"Essentially speaking, the stone castle has hidden runes, and the aura fluctuations are hidden. What Black Calamity sees in the eyes should be just a strange camp with a little bit of the breath of living people. As long as the things in the camp disgust it more than attract it, it can Complete the expulsion. Therefore, the camp must ensure that all living people do not go out. Increasing the presence of living people will increase the attraction.

Keeping an eye on the insect man, Yu Hong did not go out personally to lure him away this time. He also wanted to try out the specific power of the strengthened wind and fire spirit-slaying array.

puff.

puff.

The bug man slowly approached the camp fence.

It should be the position of the eyes, looking into the camp. One step, two steps...

puff!

In an instant, its whole body turned into a swarm of insects, flying straight over the fence and towards the stone castle. But the moment it flew into the fence.

The doubled formation took effect instantly.

A group of transparent air jets out from the ground, hitting the insect swarm transformed by the insect man.

The air flow was like a pillar, completely enveloping the insect man and continuously impacting it. At the same time, black sparks appeared inside the insect swarm, trying to ignite the insect man. Suddenly, the flying speed of the insect swarm suddenly slowed down. many.

But even so, the short distance of thirty meters outside the courtyard was not enough for it to fly. It was seen that it was about to fly to the wall of the stone castle.

Suddenly, a figure jumped out from the inner courtyard and threw a radiation grenade at it. Bang!

Seven thousand negative radiation exploded, but this was even more insulting to the bug-man. At the same time, it was attracted by the rich aura of the living person, turned sharply, and pounced towards the human figure.

But with a bang, the figure actually started running in circles in the outer courtyard at a speed no slower than it. The insect man was not as fast as Yu Hong in the open area, and now it was hindered by the formation, and it suddenly became even slower. So. The two chased each other and quickly ran around in a circle.

Followed by two laps. Three laps. Four laps...

The black sparks on the insect man's body turned into black flames, and layers of black insects were burned to death and fell down like gravel. As it circled around, it had stayed in the formation for more than ten seconds.

Yu Hong ran, slowing down from time to time and waiting for it.

He was relieved to see that the insect man's body was significantly smaller than before.

It should have reached the maximum damage limit of the array now, which is 12,000 units of damage per second. Even if it is an insect man with a total red value of hundreds of thousands of radiation, it cannot withstand the burning at this speed." Sure enough.

Ran a few more laps.

The insect man's size is half the size when he came in.

It was only 1.4 meters tall at this time, like a dwarf. When it realized something was wrong, it immediately turned around and rushed towards the outside of the formation. Seeing this, Yu Hong simply stopped and tried to lure the opponent to continue chasing.

But this insect man obviously had a certain amount of intelligence and did not look back. He still kept his human form and rushed out of the camp, disappearing in the mist of the mountain forest in a blink of an eye. Yu Hong chased after him and stood in the courtyard outside the camp, looking out.

He didn't dare to chase them out because apart from the formations and props, he didn't dare to come into contact with the bugs in person. Standing inside the fence, his face finally relaxed a little.
Chapter completed!
