Rebirth: All Patents, Cutting off the European and American Tech Tree

#903 - Chapter 903: A complete lead, a crushing victory! Retreat? A chance for a total attack and an

What is an alien civilization world like?

Unlike the surface, with its endless and distant sky, since space can extend infinitely, the underground world has a rock layer as its ceiling.

Here, the height of the 'sky' is at most less than a thousand meters.

The light source is created through technology.

It's as if many small suns are suspended at the top of the so-called sky, simulating the alternation of day and night on the surface.

There is light.

Naturally, there are plants and animals.

There are also lakes, rivers, and so on.

The ecology is not much different from the surface, but the plants and animals have obvious differences.

The truth is.

Over 70% of the area between the Earth's crust and mantle is solid, playing an important supporting role.

The space for alien civilizations to survive in is the remaining less than 30% of hollow areas.

Of course, the surface world is 70% ocean, and land area is only 30%.

The surface world is on the outer ring.

The underground world is on the inner ring.

The diameters are different.

Even if they both account for 30%, the areas are different.

But given the Earth's radius, the difference between the outer and inner rings is so small that the area difference is actually not that significant.

Most of the area is solid, so how can they dig holes accurately…

It's very simple!

Seismic wave detectors can deduce the underground medium structure.

Gravity analyzers can analyze the density of materials.

Even without Chen Hao developing new equipment, they can determine where cavities exist.

Besides, didn't they also obtain a lot of information from Ling Duo?

In short, the underground world has no ocean, and the water area only has lakes and rivers, which is smaller than the land area on the surface, and the population…

Is only over a billion.

In contrast, the surface world has nearly 7 billion people!

In the end, the alien civilization's ancestors had heaven-defying technology and could simulate an environment similar to the surface, but the resources are ultimately not as good as the surface, and they cannot support so many people.

There are many factors in the victory or defeat of war.

Among them, two factors are the most important.

One is military industrial technology.

The second is resources.

Resources are not only natural resources, but also a huge population base.

Undoubtedly.

The surface civilization has an absolute advantage!

…

Four Divine Weapon mechas charged forward.

Specially to deal with giant mechas.

Behind the Divine Weapon mechas, thousands of drones followed, both to monitor these mechas and to transmit the real-time battle situation at the forefront of the legion.

A thousand meters apart.

The fifth Divine Weapon mecha followed closely.

This mecha does not participate in combat.

The forces are divided into four routes.

This is one of the routes.

The four routes of troops receive in real time all the war commands transmitted from the cockpit of this Divine Weapon mecha.

Inside the cockpit.

Ling Duo is responsible for operating the mecha.

The Divine Weapon mecha is almost twice as tall as the Black Armor, and weighs several times more. The cockpit space is also much larger, easily accommodating three people—besides Ling Duo being responsible for operation, Chen Hao and Shi Dali are also there.

The reason for bringing Shi Dali along…

Is to reassure him!

Ling Duo had no choice.

In order to give her important relatives and friends a chance to survive after the war, she had to agree to Chen Hao.

Chen Hao also said that she only needs to follow behind and does not need to participate in the battle, which greatly reduced her psychological pressure.

Just following.

No fighting!

No killing!

It seems… there's no problem, right?

Even if she doesn't agree, Chen Hao can also drive the Black Armor, but the safety is lower.

In fact, there is not much danger.

The most dangerous charge is left to those Divine Weapon mechas. Once the Divine Weapons kill the giant mechas, ordinary single-soldier mechas have no power to fight back against the Black Armor—these are what she has seen with her own eyes.

At this moment!

A dozen Black Armors are engaged in battle around the Divine Weapon mecha she is piloting.

First, particle cannons attack from a distance.

Once the alien single-soldier mechas get close relying on their numerical advantage, the Black Armor immediately takes off to create distance, and once in the air…

The single-soldier mechas do not have long-range attack capabilities.

They are all sitting ducks!

Chen Hao, wearing sunglasses, is responsible for overall strategic command.

Hundreds of thousands of drones are building a communication relay system throughout the underground world.

The scenes from the four attack points are aggregated through drone relays and presented in a virtual reality manner, and with the help of powerful AI technology, he can switch to any perspective with just a thought.

“Kill ordinary people? Stop!”

At one battlefield.

After breaking through the enemy's defense line, seeing that they were about to enter a city, some Black Armors were attacking ordinary people.

He immediately stopped it: “Destroy the enemy's military power at the fastest speed!”

Ordinary people?

Won't they be at our mercy after the war?

Destroying the enemy's war power is the core.

Including all types of mechas, defense devices, arsenals, etc.

As long as the military is completely wiped out, the rest will be nothing to worry about.

Advance!

Resupply!

Advance again!

First, obtaining Ling Duo's memory, and later, those captured pilots also 'contributed' their memories.

It can be said that Chen Hao's understanding of the underground world exceeds that of most people in the alien civilization.

Admittedly, the underground world is very large, but under this high-speed advance…

It's a one-sided game.

Without difficult street fighting, the advancement speed is quite fast!

The four routes of troops are advancing simultaneously, first disintegrating the war power spread throughout the underground world. According to the current estimate of the battle situation, they will converge on the central city within three days.

Central City.

Is the only capital!

…

Divine Weapon mechas and Black Armors have flight capabilities.

Hundreds of thousands of drones provide logistical and communication support.

This is what can be seen in the underground world.

In fact!

The entire surface civilization is providing logistical support.

Led by China, including all countries with better economic conditions and relatively abundant resources, are sparing no effort to provide resources.

No country is hiding anything.

Firstly.

This is the decisive battle between the two civilizations!

Once lost, even if not completely destroyed, they will inevitably be severely damaged.

Secondly.

Any country that hides anything and engages in small actions…

In the war with the alien civilization, China only invested the army.

There are also the other three services!

Today, any country in the surface world, even the once strongest North America, can flatten it—annihilate the country—within a few hours!

In short.

After the war started, with the blessing of strength and logistics, the four routes advanced all the way.

There seems to be no suspense anymore.

Until a few hours later…

“Something's not right!”

A general reported: “Commander! In the city I am attacking, there are very few single-soldier mechas on the periphery. Drone scans show that even the number of ordinary people in the city has decreased significantly!”

It's not just his route of troops?

It's the same on the route where Chen Hao is.

From the beginning, there were thousands of mechas in a single city, but now there are only twenty or thirty guarding it.

In other words.

The alien civilization's military and civilians have all withdrawn!

Rout?

No!

If it were a rout, there should not be a single mecha left, and instead fewer civilians would have left.

If it's not a rout…

Then it's the order of the highest level!

“Want to withdraw?”

Chen Hao quickly circled a point on the virtual reality map with his consciousness: “All troops, listen to the order, stop the original battle plan! Can mechas running on legs be faster than those that fly? Take a day's worth of supplies and head straight for Central City!”

“Build inner and outer ring formations ten kilometers outside Central City.”

Originally, he wanted to sweep through each city one by one.

Eliminate the war power of each city.

Unexpectedly…

The opponent took the initiative to create a great opportunity for him to annihilate them in one fell swoop.

In war, there is another factor that is very important, and that is the speed of the army's movement.

So what if they withdraw first?

Can running be faster than flying?
