After the multinational conference, the various departments in the Black Great Wall were operating in full swing.

Everywhere you look, the soldiers are doing their own thing.

Moreover, the Black Great Wall represents the research of the earth's top gambling technology, and with the help of Lin Chen and the envoys, spaceships are constantly being manufactured.

Battleships such as the Taishan, which were built at the same time as the Mangdangshan, have been successfully manufactured one after another, and there are even fewer space fighters.

Glenn also found time to construct a Battlefortress.

Because the solar system is so long, there needs to be a place where soldiers can be stationed at intervals.

Battlestar is the best choice.

Because Battlestar is more practical than Spacedock, there is no such thing as maneuverability in Spacedock, and Battlestar can be transferred at any time.

During this time, Lin Chen also took the time to go back to the Douluo Continent and added some good things. As a price for helping the earth, he also asked for a lot of space fighters.

The speed of the space fighter can be comparable to the speed of Lin Chen's modified helicopter, or even better.

And what Lin Chen brought back was just those Douluo Continent's slightly older material treasures, on the Douluo Continent, those medicinal materials that were on the earth basically didn't transform into shapes, and I don't know why.

And with the support of medicinal materials, a large number of high-grade starry sky potions have also been released.

The starry sky elixir made from those medicinal materials found on the earth was not comparable to the medicinal materials on the Douluo Continent at all.

However, the consumption of medicinal materials is also very large, and the medicinal materials prepared by Lin Chen, plus the previous ones, are only tens of thousands of starry sky elixirs produced.

Don't look at the number of tens of thousands, which is quite large, but for the entire solar system defense line, this number is very small.

Therefore, after everyone's discussion, it was finally decided to build 15,000 space fortresses on the entire solar system defense line, and each fortress was guarded by a high-level warrior injected with high-grade starry sky potions and 5,000 soldiers injected with ordinary starry sky potions.

That is, more than 70 million earth troops will be stationed on the entire solar system defense line, which is already very terrifying for ordinary civilizations.

After the decision was made, the question to consider was whether to distribute these more than 10,000 space fortresses.

For the entire solar system, this number is too large to be fully covered.

In response to this problem, it was the method proposed by Lin Chen to solve it. That is, these fifteen thousand empty fortresses do not have to be completely connected, they can be evenly distributed over the entire solar system defense.

After that, between all the battlestars, build space wormholes that can complement each other. Then the Blade 7 is responsible for monitoring the entire solar system, and as long as there is a little bit of wind and grass in that place, it is completely possible to teleport to each other between Battlestars.

As for why it is not teleported between the earth and the space fortress, it is because of the problem of energy consumption, when there is a battle situation, the energy consumed will be a literal number when there is a large-scale teleportation from the ground on the earth to the defense line.

And if you teleport between Battlestars, in addition to the energy of the solar system, you can also use some energy scattered in the universe, and you can completely ignore the consumption of energy in the solar system.

The biggest problem now is building a space wormhole. After all, Rose, who is proficient in space, is not on Earth now, but at Morgana.

In the end, it was Lin Chen who exchanged a spatial teleportation array diagram from the system, and tried to build his own spatial teleportation array.

After the success of the earth experiment, this kind of thing is none of his business, after all, if he has to do everything himself, it is estimated that his physique during the tribulation period will not be able to bear it.

Here, Lin Chen was basking in the sun on the roof of the building.

Suddenly, a wormhole appeared in the space behind him, and Leng walked out.

Looking at Lin Chen, who was basking in the sun, she smiled and said, "Yo, I can't imagine that the whole earth is busy, our Lin Damale God is so leisurely." Actually basking in the sun here. ”

Lin Chen stretched out his hand to pull away from the cold, and said lazily: "If you have something, don't block the sun." “

Regarding Lin Chen's attitude, Leng was not angry. Learn from Lin Chen lying on the chair next to him, basking in the sun.

"Well, it feels good, I didn't expect you to have such a good way to relax on Earth, and it feels really good to bask in the sun here."

Lin Chen didn't have words, these unnutritious topics would only waste his spirit.

"By the way, this time I came to ask Hexi to ask you, since you have a way to resurrect Kaisha, do you have a way to solve the mystery of the black hole?"

In the battle with Hua Ye, the biggest headache for Hexi was not the Void Engine, but the Black Hole Engine. You must know that in the universe, the formation of black holes can devour everything it encounters, and even light can't escape, and it is precisely because of this that Hua Ye is the most tricky existence.

"Black Hole Engine?" Lin Chen smashed his mouth and said, "I don't know, I haven't studied it." ”

Lin Chen didn't fool people by saying this, he really hadn't studied the existence of the black hole engine.

He was stunned for a moment, and said a little uncertainly: "Since the time you saved me, I have been very interested in you, and when I knew that you could resurrect Kaisha, I even felt that you were an omnipotent god, and now there will be something that you don't know?" “

"God?" Lin Chen snorted coldly and sat up, "Do you know the void that Carl has been studying? ”

"Of course I know, Carl, that madman, according to him, he left the Hypertheological Academy to study the Void." When it came to the void, Lin Chen could hear the trace of fear in Leng Leng's words.

No matter who it is, fear always stems from the unknown, and it is impossible to change.

"Then do you know if there really are other civilizations in the Void?"

Lin Chen always felt that the void that Carl studied was not so simple. After all, he knew that the world of cultivating immortals must exist, and even the myths of the earth were true.

When those super-powerful worlds appear, God, it will be nothing.

And now the gods of this world, for those who are really great gods, are just characters who are pinched to death.

"Maybe it is. Queen Kaisha once said that if Carl really opened the door to the void, it would be a disaster for the known universe. ”

When this topic was mentioned, Leng couldn't help but think of the words of Kaisha and them at the beginning, she had never seen Queen Kaisha worry about anything so much.

"That's right, the void really exists, but I don't know what kind of world the world behind the void is, if this world is lucky enough, it may survive if it encounters some worlds with exact civilization divisions. But if you encounter advanced civilizations that like to expand, it may be a disaster. ”

Until now, Lin Chen didn't know what kind of world this world behind the void was, because the void gate was not opened, and no one knew.

It is precisely because of this that Lin Chen will silently help the earth establish various lines of defense, which is considered one of his homes after all.
