The group of pterosaurs that covered the sky and the sun flapped their ugly wings, hovering over Su Chen and refusing to leave.

At Su Chen's feet, on the hard rock wall, there were small pits the size of thumbs everywhere.

Outside the pit, you can see a foreign object that looks like gravel.

This is actually the saliva that pterosaurs drew from gastric juice.

After being spit out of the mouth, it absorbs a large amount of oxygen and hardens.

Because of its stone-like appearance and extremely destructive power, people who have not experienced it will mistakenly think that the pterosaur is spitting stones.

Although the saliva is hardened, the surface layer is still corrosive.

Even the top human powerhouses with strong physical defenses have to walk around when they see this.

However, Su Chen had no such concerns.

Nearly a hundred pterosaurs hovered above him, sucking saliva from the gastric juice and aiming at Su Chen's skull, constantly spraying.

However, no matter how accurate they were, these hardened saliva would still inexplicably and suddenly change direction when they approached Su Chen's body.

This group of pterosaurs couldn't figure out the situation and could only keep attacking.

Trying to break down the invisible barrier in their perceptions.

"Fall!"

The pterodactyls overhead gathered close to three-quarters of the total.

Su Chen felt that the time had come, and took the initiative to launch an offensive.

This 'fall' is very penetrating.

Nearly a hundred pterosaurs above his head were traumatized at the same time, falling at his feet in droves.

Don't look at the huge size of these pterosaurs, their hideous appearance, and their mouths can spit corrosive saliva.

In fact, most of their realms are second-level beast guards, and they can't withstand the hypnotic effect of the trick sound at all.

The vertically descending pterosaurs did not die, but fell into a brief coma.

But.

When they landed at Su Chen's feet, it would be their sacrifice day.

This wonderful scene was seen by many human powerhouses.

Qingqing's brows tightened, he found that Su Chen had been promoted, and he had been promoted without warning.

There were too many secrets on Wang Kui in front of him, so much so that he wondered if Wang Kui had been taken away.

Qingfeng beside him noticed his father's strange gaze, and hurriedly pulled him in the opposite direction of Su Chen.

Before, he was worried about Su Chen's safety, but now it seems that he is too worried.

Su Chen knew in his heart that these top powerhouses in Qingqing would more or less notice his abnormality.

But now I can't take care of so much.

As long as he completes this task of cleaning up the southern front, when he returns to the Tianzi No. 3 Fortress, he can change his identity at any time.

Especially Su Chen now has illusions and illusions.

If something really goes wrong, then let the stand-in die on his behalf, so that it will definitely not arouse suspicion.

However, if the stand-in is killed, Su Chen needs to bear a very large amount of energy.

In the short term, Su Chen's combat power may fall to a level.

With a large number of pterosaurs dying at the hands of Su Chen, the human army finally had a chance to fight back.

The pterodactyl hovering in the sky was soon hit by a dense barrage of bullets.

Pterodactyls' physical defenses are so fragile that even the slightest blow can throw them off balance.

It didn't take long.

A large number of pterosaurs had many tiny holes in their wings.

No matter how hard the unbalanced pterosaur flapped its wings, it still couldn't avoid the end of falling.

In just two minutes, the group of pterosaurs that covered the sky was cleared.

The narrow road between the mountains, seeing the surviving humans climbing to the high mountains, the giant sandworms shrank sharply and burrowed back into the ground.

After the beasts retreated, the fleeing human warriors quickly regrouped.

Ten minutes later, Qingqing personally counted the number of people and confirmed that the attack of the alien beast had killed a total of 257 people and injured 390.

Being injured here means that they no longer have the ability to clean up the alien beasts on the southern front, which is equivalent to a loss of 647 people at one time.

That's not a small amount.

The total number of troops from Tianzi No. 3 Fortress this time barely exceeded 2,000, and this time it was nearly one-third.

This is the best outcome so far.

If there was no reminder from Su Chen, the convoy did not stop in time, and the soldiers were not alert, they would not have been able to flee quickly.

What's more, Su Chen harvested nearly three-quarters of the pterodactyl group, relieving them of some of the pressure.

Otherwise, the number of injured will have to be increased by at least two hundred.

The distant horizon was shrouded in darkness, and the sun disappeared from Su Chen's vision.

It was completely dark.

The convoy had wanted to speed up and finish the southern route before it was completely dark.

After several twists and turns, this idea did not come to fruition.

Once it gets dark, the activity of the beast will be higher.

Beasts that fight at night are slightly stronger than during the day, and humans are weaker than during the day.

Comparing the two, even if the human side does nothing, it will suffer.

Even if everyone understands this, they still have to move on.

If the strange beasts on the southern front are not cleaned up this time, the No. 3 fortress of Tianzi will lose the protection of the Dawning City.

When the time comes, they will definitely not end much better.

Qingqing originally wanted to talk to Su Chen alone, but it was already completely dark, and they had to speed up.

Giant worms eat everything, and nearly half of the vehicles are swallowed by them.

In order to ensure safety, Qingqing sent a small group of people to drive on.

Others continued their journey up the hill.

It's a bit tiring, but it's better than being attacked again by a giant worm.

An hour later.

Qingqing and Murong Feiyu drove out of the mountains with the follow-up convoy.

The giant worm didn't know if it was full or waiting for a better sneak attack, and it didn't reappear.

As soon as the convoy drove out of the mountains, Qingqing ordered all the wounded to be stationed at the exit of the mountains.

Many of these wounded were seriously injured, and running for a long time would bring secondary damage to their bodies.

To ensure their safety, it's good for everyone to keep them here.

Besides.

Qingqing also left behind an armed squadron of fifty people, leaving them with plenty of ammunition and supplies.

The southern route is very dangerous, and it is also not safe here.

The wounded soldiers are very poor in combat, and some people can take care of them, and they can also resist or destroy the remaining beasts in the mountains.

The terrain here is open, and the giant worms shouldn't be eyeing it.

As long as they don't shoot indiscriminately and cause a lot of commotion, it's safe here for the time being.

After dealing with the wounded soldiers, Qingqing and Murong Feiyu sped up to join An Dili.

After several battles, the casualties were too large, and they had to revisit the plan to clean up the southern front.

Out of the mountains, continue five kilometers north to the outer southern route of the Dawning City.

It is a barren and open flat land, which can be described as a flat river.

Their mission this time was to clear the area of the alien beasts and not give them a chance to merge.

However, before the operation began, they had already lost more than a third of their numbers.

With the current numbers, it's hard to make a difference.

While the three top powerhouses were discussing, Su Chen was observing the so-called outer southern line through a telescope.

It was very dark, and the ordinary telescope in Su Chen's hand had almost no effect.

Su Chen could only put down the telescope and only look at it with the naked eye.

As a sharpshooter, Su Chen's vision has been greatly enhanced.

He can see farther and can turn on infrared vision.

Unfortunately, infrared vision has a distance limit, and long-distance targets still require professional equipment.

In Su Chen's field of vision, many wriggling small gray dots could be seen in the pitch-black world.

Those gray spots should be the alien beasts on the southern front of the periphery.

Su Chen quickly withdrew his gaze.

Because the distance was too far, he could not determine the exact location of the targets, as well as the number.

Continuing to observe will only make his eyes more tired, and sheer consumption will not bring him substantial gains.

Qingqing and the three didn't discuss it for too long.

Before they set off, they had already calculated many possibilities through high-level meetings.

Because the danger of the southern route was so high, even if only one-fifth of the people left the mountains were left, they would not be surprised.

This is a high-stakes mission.

The top leaders of the three major forces unanimously agreed that the number of people who could survive would not exceed one-tenth of the total number at most.

The three Qingqing people, who had personally experienced several battles, were even more convinced of the conclusions they had reached.

This time, I'm afraid that except for the most powerful handful of people, everyone else will have to die here.

Qingqing, who discussed what to do, quickly returned to his off-road vehicle.

He ordered the team to move on through the walkie-talkie.

Su Chen took a deep look at him, and he saw tiredness and disappointment in Qingqing's eyes.

This does not bode well.

Su Chen had the urge to leave the convoy and rush back to the Tianzi No. 3 Fortress alone.

Qingqing turned off the walkie-talkie and glanced at Su Chen behind him.

"The next action will be divided into three groups, I will take one group, Murong Feiyu will take one group, and An Dili will lead one group."

"Antili is very interested in you, and he asked me to ask you if you would like to go to his group, and he will do his best to keep you safe."

"What do you think?"

"I can't do my best to keep you safe, but as long as you stay with me, I'll definitely help you."

Qingqing has seen Su Chen's methods, Su Chen's realm is not high, but his potential is very strong, and his strength is not weak.

He won't say big things, and he will definitely keep Su Chen safe.

Besides, even if he said it, with Su Chen's temperament, he wouldn't believe it.

Su Chen didn't know if Andili was really interested in him, but he was sure that Andili would really protect him.

Before Su Chen left, Ankang made it clear that Antili was his backing.

Ankang will never joke with his life.

Su Chen hesitated again and again, feeling that Antili's side was more reliable.

But in the dark, his heart seemed to want him to stay here.

Su Chen believed in his inner choice.

"Thank him for me, I choose to stay."

Qingqing nodded and informed An Dili of Su Chen's choice.

After finishing speaking, Qingqing turned off the walkie-talkie again.

"Your choice will not be wrong, the route chosen by Antili is the most dangerous, if you choose to follow him, with his temperament will protect you, but not necessarily you."

The commander-in-chief of the clean-up operation was Antili, and the most dangerous road had been dictated by him from the very beginning.

"What about our route?"

"The Snow Hawks have taken a lot of benefits, so their route is more dangerous than ours."

"As long as there are no accidents, our route is the safest."
