After coming out of the imperial capital, Ye Chengcheng has been chattering, chattering in Ye Fan's ear.

"Eh, boss, who the hell is that old man? He looks plainly dressed, but he seems to be a very powerful person, and he can still agree to our request at such a time? Ye Tingcheng opened his mouth curiously.

"That's the big guy who is working behind the scenes, don't look at him ordinary, but he is hidden in the city, and people can't be disguised." Ye Fan opened his mouth to admonish.

"Oh, I see." Ye Qingcheng also nodded.

Soon, a small white reflection appeared in front of everyone's eyes, but the reflective light source was on the ground, like a huge mirror, reflecting the sunlight into the sky.

On the ground is the first generation of the "Sky Eye" project at that time.

Abbreviated as FAST, located in the karst depression of Dawotai, Kedu Town, Pingtang County, Qiannan Buyi and Miao Autonomous Prefecture, Guizhou Province, the project is a major national scientific and technological infrastructure, and the "Sky Eye" project is composed of several major parts, such as active reflective surface system, feed support system, measurement and control system, receiver and terminal and observation base.

It mainly adopts the cable net structure, which is the main support structure of the FAST active reflective surface, and is the key point of the active displacement of the reflective surface.

The cable net manufacturing and installation project is also one of the main technical difficulties of the 500-meter aperture spherical radio telescope project, and its key technical problems mainly include: the design of the installation scheme of the ultra-large span cable net, the development of ultra-high fatigue performance steel cable structure, and the manufacturing process of ultra-high-precision cable structure.

The successful completion of the cable net project means that the FAST project has achieved substantial breakthroughs in the above-mentioned key technical difficulties.

FAST cable net is the world's largest span and highest precision cable net structure, and it is also the world's first cable net system that adopts the displacement working method.

Its technical difficulty is self-evident, and the technical problems that need to be overcome run through the whole process of design, manufacture and installation of cable nets.

Taking the development of high-stress amplitude steel cable as an example, the requirements of FAST engineering for the fatigue performance of the cable are equivalent to twice the specified value of the specification, and there is no experience or data at home and abroad that can be used as a reference.

And such a facility is enough for Ye Fan to carry out a modification according to the plan.

The large-scale gamma ray lethal device, the big killer of the Space Force in "Top of the Gods", is also the core technology of the "Requiem", reflecting a large amount of gamma rays, causing a huge range of super damage.

Even if it is a super battleship of the Space Force, if it is hit by this thing, the lightest result is to abandon the ship, and it is generally reduced to ashes on the spot.

And the main principle of this mass killer is not how powerful its gamma rays are, but how to concentrate such a large amount of gamma rays at one point and then emit them in a straight line.

Ye Fan didn't want to use it to emit gamma rays, because not to mention where the source of gamma rays should be captured, the impact of gamma rays emitting on a large scale in the atmosphere alone is absolutely extraordinary.

What Ye Fan wants to launch is a large-scale plasma stream, and the target is the moon.

The essence of the moon is the annular accelerator of the 007 project, a large artificial celestial body modified from the same year, and it is also a super star destroyer cannon.

With a single shot, the entire asteroid will be broken into pieces, and the Moon can defend the Earth from most of the meteorite fragments.

However, there is one thing that is very difficult, and that is that the project has to take into account the reflected light, the speed of refraction in the atmosphere, the speed of the moon's revolution, and the orbit of asteroids.

The Origin has been calculated countless times, and there will be a chance of three points overlapping in three days, and this one chance will only last for five seconds. 90 look

These five seconds will determine the fate of the entire human race.

It seemed like an impossible project, and a plan that couldn't be done at all.

But in any case, there was a glimmer of hope in despair.

Similarly, it is also the reason why Ye Fan quoted Dr. Kingsley's sentence.

In the end, if you still fail, then the "tombstone" project will record everyone's deeds, and the earth is the best tombstone.

Only when you fight to the end and exert all your strength and strength can you be said to be truly worthy of your heart.

Deep in the mountains and old forests, Ye Fan took off his steel armor, took off the Pisces jade pendant around his neck, and put it in the palm of his hand.

At this time, this half of the Pisces jade pendant had completely turned into a blood-red color, and it looked like it was stained with Ye Fan's blood.

"I am the second guardian of human civilization and request to establish contact with you."

"Don't pretend, I know that every time I faint, it's you who do it, and it's also Lop Nur that you guide me to, I know you have intelligence and can hear me."

[Guardian, please speak]

Soon, a line of small characters was projected on the Pisces jade pendant, and Ye Fan immediately smiled when he heard this.

"You are a product of Project 007, and at the same time, someone mentioned in the dream that this jade pendant can control all the weapons and equipment at that time, and it can also be transformed into a variety of weapons."

[Yes, but you must collect the other half of the jade pendant, and when you collect the other half of the jade pendant, you can unlock all permissions]

[It can't be turned into a variety of weapons, there are few of them, but they are all effective]

"Then can you tell me where the other half of the jade pendant is?"

[I'm sorry, I can't know where the other half of the jade pendant went, you can only find it yourself]

"But there's no time now, if I can control that ring accelerator, I only need to make a slight change of orbit on the moon, and our success rate will increase exponentially!"

[Guardian, the success rate of this plan of yours is infinitely close to 0, this is an impossible task]

"But back then, didn't you go from a wandering fleet to the glory of the final civilization? What you can do, we can do. ”

[Guardian, I think you misunderstood, the current human race is too different from our human race at that time, although the appearance is similar, but with all due respect, you are a plate of loose sand]

[You will only intrigue, deceive me, and even do not hesitate to fight each other for your own selfish interests, you are a race that kills the same kind of people, and your history is a history of war]

[If you could unite, you would have entered the first-level civilization a long time ago, but you didn't, which led to the current crisis, if the Great Commander was alive now, he would rather such a world be destroyed, this is not the world he wants to see]
