The cave is located on a steep hillside, as the reconnaissance shows, and the entrance of the cave is inclined inward from the top to the bottom, and there are huge boulders on both sides, so that its existence cannot be seen from the air or from both sides, and the cave can only be seen from a certain angle.

Although the entrance of the cave is not large, it can still allow the equipment required for the experiment to enter and exit, and the same is true of the long mountain belly inside, which makes Li Yu feel relieved, if the mountain belly cannot be passed, it will have to carry out blasting construction, which will take longer. They are running out of supplies and need to complete the work as soon as possible.

It took half an hour, and all the equipment and personnel reached the innermost part of the cave.

This cave does not look very good on the outside, but there is a cave inside, and when you go more than 300 meters inside, the whole cave suddenly expands, forming a mountainside space with a height of more than 50 meters and a radius of 500 meters.

After placing all the materials in a relatively flat place on the ground, Li Yu first arranged for someone to install lighting equipment in the cave. This only needs to be roughly installed, and it will not affect the construction, and Li Yu has a better lighting construction plan.

After the energy is activated, the temporary lighting illuminates the entire mountainside as bright as day. The whole mountainside can already be seen clearly, although the light is a little dazzling, but it does not affect the construction.

Perhaps because of the harsh life in the plateau area, there are no large animals in this cave, and there are not many small animals, such as insects, so the belly of the mountain is very clean.

The entire accurate topographic map of the mountainside has already been surveyed, and all the construction plans have been prepared. The first thing to do is to level the ground in the belly of the mountain.

The natural cave is certainly uneven, and the same is true of this cave, which has a slope of several degrees from northwest to southeast, and this condition does not meet the requirements for installing signal transmitters. If earthworks are used, even if Li Yu has a robot to carry out the construction, the time will not be short.

But it doesn't matter, Li Yu has long expected this situation, he has developed a foam material, which will harden quickly within an hour after encountering air, in the hardening process, some equipment loaded by the robot can perfectly complete the leveling task, and the ground formed after construction is not only high hardness, but also can withstand high temperature, small expansion coefficient and other characteristics.

So soon, the ground leveling task was completed by the robot.

"Lin Wanbai, come here to help!" After the ground leveling was completed, Li Yu called Lin Wanbai, who was jumping up and down, to help.

"It's coming, it's coming."

"Under the supervision of the construction of the robots, their next task is to lay flexible materials around the belly of the mountain. I'm going to go outside the cave to survey the terrain and lay out the defenses. "It takes at least three days to install and commission the signal transmitter, and although the cave is located in a remote area, it is true that the defenses are always prepared.

Biyi is too close to the border, and Kashmir is not far from here, so maybe someone in that powder keg will cross the border.

The defensive setup arranged by Li Yu is actually to install electromagnetic guns at several highest points, which are controlled by computers. In several passages around the peak where the cave is located, Li Yu asked the scout ball to stand by in the air, and if someone passed by, he would give Li Yu and them early warning.

By the time Li Yu returned to the cave in the belly of the mountain, the place had changed a lot, and the robot had just finished laying the last piece of flexible material from the top of the mountain.

This material is also extremely thin, but it will become extremely strong after being electrified, and at the same time will not change the shape of the laying, and will emit a milky white light, which is a rare decorative material in the laboratory, and Li Yu's laboratory wall is laid with this material.

When the robot sat in the anti-gravity gondola and descended to the ground, Lin Wanbai turned on the power, and the entire mountainside was shrouded in soft white light, and the entire mountainside made people feel a lot more comfortable.

After the construction of the wall is completed, it is the turn of the base to install the signal transmitter. The base is split into four pieces for easy transport, and while the base looks like just a matter of putting the four separate pieces together, it won't be that simple.

The compromise has led to an increase in the difficulty of construction. There are many layers of small energy pipes in the base, and when splicing, the error of the energy transmission pipeline at the docking is required to not exceed 1/10 million.

If the requirements are not met, the base will cause a great increase in energy loss in operation, and the electromagnetic interference of the signal transmitting device will be more serious, in addition, it will also cause the heat dissipation of the base to increase, and bring the hidden danger of explosion to the entire signal transmitting device.

So the installation of the base took a whole day and a half! The base has passed the energy pass test and meets the requirements for use.

After the installation of the base is completed, the next thing is the main body of signal transmission, which is not difficult, there is an interface on the base that has been done in advance, as long as the crystal is carefully placed and installed in place.

After the main installation, there is the energy center, fifteen small nuclear fusion units.

This is not difficult, and the base is also an interface made in advance.

At this point, the whole signal transmitter is not much done.

By this time, the belly of the mountain, which was used as a signal transmitter, had changed dramatically, and from the inside, it was no different from a laboratory

A crystal jungle-like signal transmitter towers in the middle of the cave, and the energy is connected and flashes of colorful light from time to time, which is the reaction triggered by the energy escaping. The low but pleasant resonance of the crystal sounded from time to time, which was the sound caused by the energy in the crystal being excited, thus vibrating the air.

Everything is in place, just wait for the experiment to begin.

"Li Yu, can you send a signal? I'm looking forward to it! Lin Wanbai stared at the signal transmitter.

After Li Yu checked it again, after confirming that the equipment was working well, he nodded, "Are you ready for electromagnetic protection?" ”

Lin Wanbai checked the radiation protection suit on her body, and the robot also did a good job of electromagnetic protection, and she signaled that Li Yu had no problem.

Li Yu signaled to Lin Wanbai that he could start, and just as Lin Wanbai couldn't wait to put the starting titanium crystal into the special groove, the alarm signal sounded.

"What's going on? Isn't everything checked and there is no problem, how can the main control computer call the police? Lin Wanbai said without dissatisfaction.

Li Yu also frowned, came to the main control optical brain, and checked the alarm information.

"There's no problem here, it's the defenses outside that have been touched." The source of the alert discovered by Li Yu.

"Outside? I'll take a look. Lin Wanbai put down the starting titanium crystal and opened the terminal.

"Li Yu, Li Yu, look! This is a terrorist, right? It must be a terrorist! So everyone is responsible for eliminating harm for the people, I can go and do something about them!? Lin Wanbai suddenly excitedly came over with the terminal and said loudly to Li Yu.

The terminal sent the surveillance image over.

Li Yu took a look at it and knew that there was at least a 90 percent chance that those people were terrorists. Of course, he also knew that Lin Wanbai didn't want to eliminate harm for the people at all, but was disturbed by these people!

Also, Lin Wanbai obtained the device specially developed by Li Yu, and she never had the opportunity to put it into use, so she is also very sorry, now that she has the opportunity, she will not be happy to bubble!

"Go, take No. 1 and No. 2!" Li Yu didn't think that Lin Wanbai would encounter danger, but just in case, he asked Lin Wanbai to take two robots.

"Yay!" Lin Wanbai jumped and ran out.

"Kamari, how far is it from the cave you spoke of?" A bearded man asks another bearded man. It was a team of ten men, all bearded, dressed in robes, each armed with an AK, which is the standard terrorist attire.

In the past few years, Huaxia has cracked down on terrorist activities more and more severely, and the routes commonly used by their organizations in Xijiang Province have been monitored by Huaxia to death, and it is becoming more and more difficult to enter China's territory, and after severely losing several personnel and materials, the leader of the organization has to make a decision to abandon the road from Xijiang to China, and decide to find a route into China from other aspects.

Internationally, the form that China is facing is not good, and there are some hostile countries around it, so with the help of some countries, this man named Kamari has explored a relatively safe route.

This time, Muha, who ranked second in the organization, led a team to confirm the safety of the route and look for supply points. It can be seen that the leaders of the holy war attached great importance to this opening up line.

Unfortunately, the cave that Li Yu chose as the signal transmitter was also a suitable location in the route chosen by these people, and as a large supply point, this cave was really suitable.

It can only be said that everyone's vision is quite good.

Fanatical beliefs can indeed make people push the limit, just with some water and dry food, these people have to overcome the harsh environment, two days later, they are not far from the cave where Li Yu is.

"Kamari, is this the mountain?" Muha asked Kamari.

"Yes, it's a day's journey from here, and if you hadn't lost your way, you wouldn't have found this place. That place was so secluded, there was a lot of space inside, several times larger than our previous Supply Point 1! Kamari said excitedly.

Then his expression suddenly fell, "It's a pity that we lost four brothers in order to find this place. ”

"Well done, Kamari, the organization will give you a credit, Allah will remember your contribution, and it is their honor for brothers to return to Allah's garden." Muha said with satisfaction that he was excited at the thought that he could establish a new route into China.

The rest of the team was also extremely excited, and in their opinion, it was time to make a difference. The fatigue of the journey seems to be gone.

"You're really terrorists, so it's great that I can kill you." A voice interrupted the men's delusions.
