In the dim space, a gray-white irregular asteroid floats.

This asteroid is large on one end and small on the other end, with a length of more than 500 kilometers. The widest place reaches 380 kilometers. It is inconspicuous in the vast starry sky, but when Zhang Yuan slowly approaches 10 kilometers, this asteroid covers Zhang Yuan's entire field of vision.

This is where the crystal boundary stone mine cave is located.

Zhang Yuan opened the Dark Night Walker system and wandered quietly above the asteroid. The asteroid is so huge that the crystal boundary stone mine is only a small part of it. Most of its surface still maintains its original appearance, and there is no trace left by human beings.

After a few circles, Zhang Yuan had a general understanding of the defense of the asteroid: "There are actually 16 rapid-fire guns around the mine to form the hunter system. There is an ultra-high energy barrier at the entrance of the main mine area. There are at least 50 different operating noises in the mine cave. At least 50 mecha warriors are defending this mine cave. It is not difficult to sneak in, but once you are discovered, it will be difficult to come out again."

Thinking about it, Mi Xiu knew that he could not resist Zhang Yuan's invasion, so he adopted this strategy of "please get into the trap".

If you guess correctly, once he alarms the defense system, Mishe should come to support it in a very short time.

At that time, he will be sealed in the mine by a super-high energy barrier and have no way to go, so he will have to fight with Mishe. Such a road battle will be inside the narrow mine, and his mobility is severely limited, so he will basically be done.

Finally, he stopped 5 kilometers away from the entrance of Zhangyuan Mine Cave. He looked at the spacious entrance of the mine from afar and fell into deep thought.

“What should I do to minimize the risk?”

It would definitely not be possible to break in like this. He would only have a life. If he kept taking such a risk, he would have made a mistake one day.

After thinking for a few seconds, Zhang Yuan took out a mecha that was only one person tall from the space folding bracelet.

This is a miniature mecha, equipped with a rhodium magnetic remote remote control system. This mecha is small in size and weighs only 200kg. Its power output is less than 400 horsepower. It has very low material requirements and is simple to build.

When Zhang Yuan was building a lava rhodium magnetic engine, he sometimes encountered some difficulties. At this time, he created a micro mecha to spend time and sort out his ideas.

It can be said that this mecha has almost no destructive power, and the only outstanding performance on the mecha is concealment.

Zhang Yuan has put a lot of effort into stealth technology. He has developed several new stealth technology on the Dark Night Walker system of the Earth Mecha, and has now reached the 5th generation of Dark Night Walker.

This miniature mecha is loaded with the fifth generation of Dark Night Walkers, which is exactly the same as the stealth system of the White Angel. It can be said that if this miniature mecha cannot break through the defense, the White Angel will not be able to pass through quietly.

"Mecha starts to open the Gemini Connection System."

"Si~Si~"

The miniature mecha sounded a few times, then started moving on the spot, its movements exactly the same as the White Angel that Zhang Yuan was driving.

"Done!"

Zhang Yuan looked around and scanned a high-density zone about 10 kilometers behind him. This density zone has excellent signal shielding ability. Except for the rhodium magnetic signal, the others are basically impossible to penetrate.

“Good place.”

Zhang Yuan passed by and when he walked in, he found that this was an abandoned mine, which was about 20 meters deep, and there were many low-quality grain boundary stone ores distributed on the four walls of the mine. I think this should be the reason for signal shielding.

He controlled the White Angel mecha to hide in the mine, turned on the Dark Night Walker system, and then switched the control mode to simulate virtual cabin mode, and the viewing angle of the White Angel's internal wraparound hologram screen was switched to the miniature mecha.

The current situation is that he used the White Angel as a remote remote control cabin to drive a miniature mecha into the crystal boundary stone mine to investigate the situation. Even if he was discovered accidentally, he would at most sacrifice a random mecha that he built was insignificant.

He carefully manipulated the miniature mecha without rushing forward. He stared at the mine scanning waves that were fed back by the miniature mecha.

The detection waves around the mine are very dense, with almost no blind spots scanning. However, there are many interference signals in the starry sky, especially the distance from the stars is not far away, so the signal interference is even more serious.

What Zhang Yuan had to do was to take advantage of a large-scale cosmic signal explosion and break through for a distance.

This requires patience, and Zhang Yuan does not lack this at the very least.

About half an hour later, a violent electromagnetic explosion caused by the explosion of stellar flares arrived, and even the angel holographic screen appeared slightly ripples.

"Good opportunity!"

Zhang Yuan immediately manipulated the miniature mecha and ran forward. His running path was also very particular, which was the line with the weakest detection waves.

‘Si~Si~’

The peak of this wave of electromagnetic explosion lasted for about 5 seconds and began to decline. Zhang Yuan had already calculated the other party's detection threshold. When the electromagnetic explosion dropped to a certain level, he stopped moving forward immediately and patiently waited for the next opportunity.

Generally, a flare burst like this will last for an hour or two, and there will be several magnetic storms that break through the opponent's load limit in the middle. Zhang Yuan was lucky. After about 11 minutes, another magnetic storm arrived.

After walking and stopping for more than 3 hours, Zhang Yuan finally arrived at the entrance of the crystal boundary stone mine cave. As long as he walked 50 meters forward, he would be where the ultra-high energy barrier was.

From the perspective of the micro mecha, you can see a dark blue spherical force field, which wraps the hole tightly and has almost no flaws.

The reason why this force field is called a super-high energy barrier is because it contains terrifying energy. Once an object invades, the force field will instantly penetrate the invader and cause super high temperatures of more than 100,000 degrees in the object.

Such energy can destroy the structure of all matter that exists in the universe in an instant, without any exception.

Of course, this is the result of confronting this force field. If it is not confronted, it would be a different matter.

Just so happens that Zhang Yuan has a way to penetrate the force field without causing the reaction of the force field. This is a quantum engine, which can turn the existence of a physical body into a quantum wave and quietly pass through this force field. The only disadvantage is that the quantum engine is extremely energy-consuming and cannot be used too much.

"Start the quantum engine, the quantization degree is 98.21%, lasting for 1 microsecond, and the target coordinates (11.21.98)."

"Executing Command"

After a moment, the hologram screen in front of Zhang Yuan appeared in an extremely brief trance. After the image returned to stability, the miniature mecha was already standing quietly inside the ultra-high energy barrier.

The inside of the barrier is the entrance to the mine. In order to meet the needs of large transport spacecraft, this entrance is very large, 200 meters high and 200 wide. Facing such a huge entrance, the miniature mecha is like a small ant on the ground.

Transporters are constantly flying in and out at the entrance of the mine. At the entrance next to the mine, a large number of rapid-fire fortress cannons are arranged. Usually, there are 1 to 2 mecha warriors standing around the muzzle, and a large number of micro-detection vehicles are arranged in the entire mine space.

These miniature aircraft are densely packed in various hidden corners that cannot be reached by mechas, leaving almost no blind spots.

"In order to protect this crystal boundary stone mine, Mi Xiuzhen has made up his capital." Zhang Yuan couldn't help but sigh.

However, there is no complete system in this universe. The more complex the system is, the more likely it is to have fatal flaws. As long as you have patient and careful observation, you can always find loopholes.

After standing by the ultra-high energy barrier and observing for 5 minutes, Zhang Yuan discovered an interesting phenomenon.

He found that when the spacecraft transporting the grain boundary stone rushed out from the depths of the mine, a large number of high-energy jets would appear near the jet of the spacecraft engine. In order to protect itself, these micro-detection vehicles would avoid this jet 2 seconds in advance.

Then the question arises.

The destructive power of this jet is enough to easily destroy the miniature aircraft, but it is not enough to cause damage to Zhang Yuan's miniature mecha. At the same time, because the aircraft avoids it 2 seconds in advance, there is a time difference here.

For at least 2 seconds, there is a space in the mine interior space, in which there are neither jets nor micro-detection vehicles.

If the time when the aircraft flies back and fills the gap again, then Zhang Yuan will have at least 3.3 seconds of action after a transport ship appears!

These all provide opportunities for Zhang Yuan to sneak into the mine silently.

After discovering this flaw, Zhang Yuan did not rush to act. He stayed for another 2 hours. During these 2 hours, he did two things: one was to count the transportation schedule of the transport spacecraft; the other was to observe the flight trajectory of the micro-detection aircraft.

Two hours later, Zhang Yuan was already sure.

He took a deep breath, looked at the mecha guards on both sides of the mineway, and began to silently think in his heart: "9,8,76,5,4,2,1 spacecraft is here!"

"Woo~" The sound of a low jet engine sounded, and a bulky iron-gray transport spacecraft rushed out from the depths of the mine. At the tail, there was a translucent high-speed jet. Wherever it passed, the detectors dodged to both sides like mosquitoes, and a clear gap appeared.

"It's now!"

Zhang Yuan immediately used the maneuvering step method of "White Ape Jumping". The entire micro mecha suddenly bounced up and took a few steps in the air. With each step, a very insignificant air ripple appeared under the mecha's feet. This was the anti-gravity force field.

It flew across the air with a miniature mecha.

Three seconds later, Zhang Yuan used the scanner to see a hole that appeared after the detector dodged at high speed and hid in.

After hiding in, he silently said to himself: ‘3, 2, 1, the spaceship is here!’

"Woo~" Another transport spacecraft rushed out, and the gap appeared again, and the hole that Zhang Yuan had just hiding was about to disappear.

Zhang Yuan immediately pulled away. When he left, the closest miniature flight detector was less than 5 cm away.

In this way, Zhang Yuan borrowed four gaps in a row and successfully advanced 500 meters. At this time, a spacious square appeared in front of him. There were a large number of intelligent robots busy on the square. They kept loading the crystal boundary stones onto the transport spacecraft, without stopping for a moment.

There are too many moving objects in this square, so the miniature detection robots in the air are greatly reduced, and they are no longer almost covered with air as before.

When he arrived here, Zhang Yuan breathed a sigh of relief, found a corner to hide, and then began to observe carefully.

The loading and unloading area is very wide, at least 300 meters high and has a length of more than 700 meters. Most of the people working here are intelligent robots, but there is an entrance sealed by transparent materials on the stone wall on the left side of the loading and unloading area.

Through the transparent materials, Zhang Yuan could see people walking around inside, and mechas were in and out from time to time. It should be the place where the mine security guards lived.

Zhang Yuan stayed there again and observed patiently.

This time, he waited for 5 hours. He not only observed the transparent entrance, but also observed the whereabouts of mining robots. The most important of them was the number of spiritual rough stones in the crystal boundary stones transported back by mining robots.

Five hours later, Zhang Yuan determined his whereabouts.

It is one of the three largest mines next to the loading and unloading area. It is located on the left of the mine security area. The grain boundary stone transported from this mine channel is not only of high mental strength, but also more pure.

Let me put it this way, if there is a core area of ​​this grain boundary stone ore, then this mine cave must be the closest channel to it.

However, Mixiu obviously thought so. The strict defense he arranged in this mine road made Zhang Yuan feel a little tricky.

Let’s not talk about the micro detectors densely covered mines. The mine security guards will patrol the mine every 10 minutes. A large number of high-strength material mounts are also arranged inside the mine. Once an accident is discovered, the mount is closed, which is really a bad idea and the ground is not working.

How to get in this place?
