"Indeed, the environment is a bit bad!" Yi Xin also nodded, especially since he was now in "Xu Heng". When comparing the two, the gap was too obvious.

"Ran Quan's world is indeed terrifying, meow!" Meowpass nodded in understanding. She couldn't imagine how people could survive in such an environment...

"Uh~ You misunderstood." Ran Quan said. Although he had briefly told everyone about the situation in his own world before, it was just a simple explanation. Now he saw that everyone had some misunderstandings.

Ran Quan quickly explained to everyone the situation in his world and where he was now.

"So this is the world above ground! It's so scary. No wonder you have to move underground..." Lin Zifeng nodded in understanding. No wonder, it's really impossible to live on the ground like that.

"The environment is indeed quite bad!" Lin Ze nodded. His world is also the end of the world, but there is one thing, just a little bit of game-like, and the overall situation is okay. Although it is the end of the world, it is hard to say whether it is a game of gods or a new evolutionary path for mankind...

Compared to Ran Quan's world, Ran Quan's world should be called the end of the world... Look at this wasteland...

But...Lin Ze's world is not "bad" either. After all, extreme weather often occurs. People in their world often ask: What "weather" will be refreshed today?

While Ran Quan was chatting with them, the robots finally appeared in the distance.

"Is this the alien invader from your world, Ran Quan?" Everyone looked at the robot that appeared in the distance.

A large number of robots came in rows.

At a glance, there are at least tens of thousands of them.

And there were actually more than one large spider machine!

There are three in total.

There are three directions with quite a large gap between them.

"Everyone!"

At the command, all weapons were ready to go.

When the robot enters the attack range.

"Fire!"

Da da da~~~

Whoosh whoosh whoosh~~~

Countless energy bombs and energy missiles were launched.

boom! boom! boom!

The war started instantly.

The robots immediately launched a counterattack.

Those "mass-produced robots" rushed over one after another, each one like a suicide squad, with their hands turned into air cannons, firing as they charged.

And those spider machines are even more outrageous.

There were N holes on the eight legs, and countless small missiles flew out from them.

boom! boom! boom!

Although these missiles are small, the power of each missile is several times greater than the air cannon of the "mass-produced robot".

Not only that, a strange machine also emerged from the back of the spider robot... and then it opened up... an energy barrier!

boom! boom! boom!

On Ran Quan's side, countless fire attacks on the energy barrier were all blocked and difficult to shake.

Then, the spider machine's "butt" opened, pulling out countless "mass-produced robots" like rain.

Depend on! This machine also has explosive soldiers? !

Naturally, everyone noticed this scene, but fortunately, the capacity of these spider machines seemed to be limited.

It spit out about a hundred mass-produced robots and then closed its "butt" again.

In other words, these spider machines are actually just a "transportation machine"? However, it still takes into account the output and defense functions of the "battlefield".

So...this large group of machines may...still be just the vanguard of that "civilization".

This "army" may seem powerful but is actually vulnerable to the combined power of the three major technologies, that is, the entire underground world's civilization and the power of all mankind.

The battle lasted less than 10 minutes and was over.

The ground was in a mess, but the environment on the ground was not very good to begin with, and now it has just changed its appearance at most, it is still just as bad anyway.

Although they won, everyone's faces were not very good, especially after seeing the power of these machines, they all looked very solemn.

After all, the technological power demonstrated by those machines is very strong! Not easy at all!

This is just the vanguard, there must be more powerful technological forces behind it.

After all, who comes up and just zooms in?

"It seems that this plan needs to be put on the agenda ahead of time!" The three leaders looked at each other and hit it off. The plan that had been discussed before was directly approved. After all, this was no longer a matter of worrying about small gains and losses.

But we have to face the battle in another world!

Sometimes, humans fight among themselves, but are united against foreign enemies.

Human beings themselves are extremely complex creatures.

The original plan is the "Dawn Project" that is currently being implemented in the ground world.

That is the current defense line construction.

Although we can’t stay in the ground world forever, we can switch batches in the early stage.

It would be best if the defense line could be established above the fifth defense line. One defense line is 10 kilometers, which means the distance should reach 50 kilometers.

In this way, no matter what the situation is, there can be a minimum guarantee.

Of course, if that were all, they could have done it long ago, and there would not have been a need to wait so many years before proposing this plan, or even putting it on the implementation schedule.

The reason they dare to do this is because of technological advancement and breakthroughs.

They can already "build" an area suitable for human survival on the surface world.

That is, it can resist the influence of "wasteland radiation" and "extreme weather" from the ground world.

Of course, the cost is very high, and it is impossible to transform the entire ground world.

But if you take a small area, that's not a problem.

Although it is very expensive, it is still affordable for the three major technologies.

Plus the current situation.

There was no hesitation at all.

After all, the war cannot be taken underground!

That would destroy the entire underground world.

The underground is not the same as the world above ground. The structure and overall stability of the underground world itself are created by technology and various facilities.

This is also the reason why the underground world is divided into 13 areas and they are very fixed, because if it is to be expanded, the manpower, material resources and financial resources consumed will be extremely huge!

Therefore, up to now, their focus has not only been on expanding the underground world, but on doing both in parallel, while also thinking about how to "regain" the right to survive in the surface world!

After all, you have to be prepared for everything and don't put all your eggs in one basket.

As a result, the three major technologies were put into action, which was equivalent to combining the power of the entire human race.
