The people of Yuan like to attack in the night.

After all, for them who do not have "vision", night is the best protection.

According to the summary of the "war experience" some time ago, the Yuan people's tactics are generally to gather in advance and march in advance, to reach the surrounding area of ​​the human base before dusk, and then slowly form a siege. When the night completely falls, they rush up from all directions.

With the experience of the previous few times, the base military zone directly chose to take the initiative this time.

The first batch of rockets were projected, and three or four hundred people in the abyss were killed and shattered on the spot.

The power of human thermal weapons is pretty good when facing flesh and blood.

But the losses of three or four hundred people are almost nothing for the Yuan people.

While the second batch of rockets were flying down, they chose to attack in advance.

A tide-like crowd surged out from the jungle in the distance, at an extremely fast speed. Even if the light of the stars had not completely fallen, ordinary people looked like a "wave", and could only see the group clearly, but could not see the individual clearly.

However, the military zone has been prepared for a long time.

After several months of reclaiming, the surrounding trees have been cut down and burned down, leaving open space.

After seeing the opponent's movements clearly, the military zone immediately threw a firebomb.

The incendiary bomb has a strong role in this planet.

Because the oxygen content here is high, if it is not because the air humidity is also very high, thunder can produce a burning and explosion effect.

Since heavy weapons cannot pass through the Star Gate, in order to deal with the large-scale "Abyss crowd", the military zone has already made arrangements in advance.

A lot of fuel was laid on the surrounding open space. When the Yuanren rushed over, under the ignition of the incendiary bombs in the air, the entire forest town suddenly became a sea of ​​fire.

The combustion bomb, adding ground fuel, and increasing the oxygen content, instantly lit up the entire area, turning the entire open space and even the forests in the distance into a sea of ​​fire.

Compared to the little people killed by rockets.

There were a lot of people who died in the Abyss at once.

The rocket just now took away hundreds of people in one volley.

But in this fire, the losses of the Yuan people were calculated by 10,000 people.

The smell of barbecue mixed with chemical fuel came from the field, and the painful howling of Yuanren also formed a whole.

"They ran away, Mr. Zheng, are they afraid?" Standing on the city wall, Han Dong looked at the thick smoke and jungle in the distance. Others could not see clearly what was happening in the black smoke, but he could, "The large army behind seemed to retreat to the jungle farther away."

"The Yuan people will not retreat or be afraid. If it were humans, when they were burned to death on a large scale, they would have a group fear, but the Yuan people would not."

"What's the meaning?"

"I have studied the brain structure of Yuan people. They do not have an amygdala-like area, that is, there is no fear of reflex area. Physiologically, they are not afraid of death. I guess this brain structure has something to do with fertility..."

There are still too many mysteries in Yuanren.

Zheng Senlin has never understood how the Yuan people survived on their native planet.

With such a high fertility rate, the native planet has theoretically exploded and its resources have been exhausted.

Could it be that the brain structure of "no fear of death" evolved just because it was necessary to control the population?

It seems a little unreasonable.

Although logic is flawed, science will not lie, and the Abyss who are not afraid of death will not retreat easily.

"If they are not afraid of death, why do they run so far?"

"They should be extinguishing the fire."

As expected, as Zheng Senlin said, the retreating Yuanren army did not choose to attack from other directions.

After all, they can guess that their intelligence is not weaker than humans. There should be fuel that has not yet been lit in the open spaces in other directions.

After they retreated to the distance, they first began to dig in the rear, and after digging out the isolation belt, they ignited the jungle in front of the isolation belt.

This method is a common fire extinguishing method used by fire brigades, and Yuanren can do it.

But is the forest fire easy to extinguish?

OK, not good either.

It depends mainly on the weather.

The indelible forest fires on the earth are usually caused by dry weather, wind direction and tree species.

Although the oxygen content here is high, it is easy to cause air combustion and explosion.

However, due to the extremely high air humidity, there are "rainforest belts" around it, and rainforests that are too humid are not prone to fire.

In other words, the fire here is easy to burn and extinguish.

So the fire only lasted from dusk to late at night and stopped completely.

In the jungle where the thick smoke has rolled, although the high temperature has not subsided, the people in the abyss can't wait.

"It's time to fight together." Han Dong looked at the scene in the distance, and his palms were sweating unconsciously. Some were nervous and some were excited.

In peaceful times, there has never been a war of this level.

In the fire just now, at least tens of thousands of people were killed by Yuanren.

But there are still millions of troops ready to go.

Woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo w

While everyone at the base was extremely nervous, Yuanren blew a strange horn.

The sound of the horn is extremely penetrating and can be clearly heard by humans. As the Abyss, the Abyss, with extremely sharp hearing, naturally all members receive signals.

At this moment, the tide surged at a crazier speed than the first time.

Rush rust...

Rumble rust...

Millions of troops marched and made strange noises.

The spider legs with silent function were slashing across the ground, and the sound of the city was like a symphony of the god of death.

In the military zone, various artillery fires also poured down with the symphony, connecting them with the sound of charge, completely reaching the climax.

Boom boom boom!

The artillery fire broke out in the forest and open space. Some Abyss continued to charge, but some set up equipment on the spot and bombarded the Forest Town.

These equipment are human equipment they seized. Although they are not skilled in using it now, they can also complete basic operations.

"It's your turn to end. A small team stays, and the others go to guard the gap."

Although humans used firepower to cover them, many abyss people rushed over and quickly arrived at the edge of the city wall at their speed, allowing them to climb up and enter a melee state. The human artillery defense line would collapse soon.

After all, thermal weapons are useless in melee combat.

Time is tight.

The "giant knights" on the city wall took the order to jump off the city wall, and after they spread out, they rushed towards the Yuanren.

The "Giant Knights" ran no slower than Yuanren. After charging, the two sides immediately fought together.

"Roar!" A Hulk roared and swept across the horse-slashing sword. At that moment, two Abyss people who broke through the bombing area were cut into two sections.

"It's so good!" After one round, the giants let go of the last trace of fear.

Yes, giants are also afraid.

After all, they are just experimenters of alchemy potions. Before volunteering, they were both modern soldiers and civilian adventurers.

Before they fought with Yuanren, even if they knew they were strong, they would be afraid.

After all, when watching "video information", ordinary earthlings and Abyss fight each other in close combat, just like a child fighting Tyson, they will be torn apart when they meet.

The fear brought by this video is now shattered by the scene in front of you.

A Hulk jumped up and grabbed the Ancestor who had climbed up the city wall, and then twisted his head hard.

The fear shattered along with the brain.

Strong, making cowardly people fearless.
