The threat of water droplets was successfully removed, and the plan to build 10,000 high-energy accelerators began with great vigor.

This time, no one complained or questioned it, and this plan really pinned the hope of all mankind on fighting hard to defeat the three-body civilization.

As long as the final victory can be achieved, there is no price that is unacceptable.

Qiao Lu and Liu Peiqiang looked at the foundation of the high-energy accelerator under construction in the distance, although it was not as exaggerated as the planetary engine more than 10,000 meters high, but it was by no means a small piece.

"That's what they're supposed to be." Liu Peiqiang sighed, and then shook his head, "It's a pity that they woke up too late." ”

Qiao Lu smiled and said, "No, it may not be too late. ”

At the same time, human beings will also build a high-energy accelerator on the four moons of Mercury, Venus, the Moon, Mars, Jupiter, Uranus, Neptune, Pluto and other planets.

If that's not enough, continue to look for a large enough moon, the solar system has not only eight planets, but also more than two hundred moons, five dwarf planets that have been identified, as long as there is enough to put a high-energy accelerator.

If all of them are built, let alone ten wise sons, a hundred wise sons sent by the three-body civilization will not be enough!

The cost of a high-energy accelerator is at least not as high as that of a stellar-class warship, and the three major fleets can have a total of 2,000 stellar-class warships, not to mention the fact that all human beings are now pouring their strength into building an accelerator?

If the Three-Body Civilization can't be ruthless in building more than a hundred Zhizi, then it will only be a matter of time before the human race's technology breaks through the blockade.

The second hearing on the wall-facing plan was held, but this time it was no longer to question Qiao Lu's plan, but to discuss the next step.

The Chairman of the Wall-Facing Project Committee said, "Wall-Facing Jolu, it's glad you're proving that all of humanity is now supporting your plan, even for the first time among Wall-Facers. ”

Qiao Lu's previous facers basically didn't have any good results.

At the same time, their plans have never been supported by all of humanity in the true sense of the word, and the resources that can be mobilized will always be a small fraction of them.

If it weren't for the incomparably exciting effect of destroying the water droplets this time, even as a wall-facing person, Qiao Lu's plan would not have been able to be carried out.

The representative of the Asian fleet also nodded and said: "It's unbelievable, just one gram of antimatter can penetrate the shell of a water droplet, but we all regard it as an invincible object." ”

Witnessing the total annihilation of the North American fleet and the European fleet, coupled with the fact that there were only twenty-four hours left, no one dared to put forward the idea that the water droplets could be destroyed, let alone give a scientific theoretical basis.

Qiao Lu's action is indeed extremely risky in the eyes of others, and it can be said that he will be born after death.

However, only Qiao Lu himself knows that this scheme is the result of countless discussions and experiments in the Central Academy of Sciences of the Wandering Earth, and the strong interaction force of the water droplets, the thickness of only one layer of atoms, is also rigorously calculated, and it is not the result of luck at all.

The only real obstacle is the sharp-angled steering ability conferred by the vacuum Valssex electric field vortex ring of the water droplet, but this advantage is also due to the fact that the Trisolaran civilization is eager to destroy the Ark, which claims to have a gravitational wave generator, causing the water droplet moth to hit the muzzle like a flame, and is finally solved by an antimatter armor-piercing projectile.

"But we still can't take it lightly, there are nine droplets left, and they will reach Earth in three years, and we will have enough time until we destroy them all." Qiao Lu said.

The chairman nodded and said, "Indeed, this is what we want to discuss with you today. ”

Hines then continued: "The time it took for the nine droplets to reach the solar system is only estimated based on the speed and acceleration at which they passed through the last patch of interstellar dust four years ago, and unlike the first droplet that reached the solar system, their engines do not emit light when they start, nor do they emit any high-frequency electromagnetic radiation that can be located, most likely after the first droplet was successfully destroyed by humans, and they adjusted themselves to themselves." It is difficult to search and track such small, non-luminous objects in outer space, and now we have lost track of them, we do not know when they arrived in the solar system, and we are not even aware of them after they arrive. ”

This is the most terrifying thing about the water droplet, it is an invisible ghostly existence that can easily lurk in the universe, waiting for the prey to let down its guard before attacking from the dead end.

The first drop of water rushing towards the Ark so recklessly was entirely the result of the Three-Body Civilization being deceived by Qiao Lu and anxious to stop the gravitational wave broadcast.

Now that they should have found out that this is a lie, the remaining nine droplets will not repeat the same mistakes.

This is the most troublesome, if the nine water droplets sneak into the solar system and find the opportunity to suddenly launch an attack on the humans, then Qiao Lu is also powerless.

If the water droplets don't hit the muzzle of the gun on their own, even if there is an antimatter armor-piercing projectile, it won't hit it.

"So what's going to do?" Qiao Lu asked.

"Creating clouds of space dust from stellar hydrogen bombs and Neptune's oil-coated material to show their tracks as water droplets pass through them is what we call snow engineering."

Before Qiao Lu could continue to ask, Luo Ji couldn't help but interject: "The last time I successfully created a dust cloud tracking, it was because I knew the general trajectory of the target, but now I don't know anything······ If those nine droplets could accelerate and change orbits without emitting light. They may even enter from the other side of the solar system! Where should this cloud of dust be made? ”

"In all directions."

"You mean to make a ball of dust to enclose the solar system? In that case, you were really sent by God. ”

"The dust ball is impossible, but it is able to create a dust ring, on the ecliptic plane, between Jupiter and the asteroid belt."

"But what if those droplets enter from outside the ecliptic plane?"

"Then there's no way. But from the perspective of space dynamics, the most likely way for the water droplet formation to contact the planets of the solar system is to enter from within the ecliptic plane, which is the No. 1 water droplet, so that the dust can capture their wake, and as long as it is captured once, the optical tracking system in the solar system can lock them. ”

This is indeed a viable solution, at least better than squirming around when the drops arrive.

Qiao Lu nodded and said, "I understand, this project will be carried out by Dr. Luo Ji." ”

"Me?".

Luo Ji himself didn't expect Qiao Lu to suddenly push him up, you must know that there are still better candidates than him.

"I believe in you." Qiao Lu patted him on the shoulder and said.
