The pungent smell filled the air, forming a thin layer of red mist, and the pile of biochemical ghosts that had been burned away by the fire did not gather again.

"We're running out of gas, we have to go back. Hearing the driver's voice in the communicator, Wu Haoming withdrew his gaze to the ground and retreated into the plane.

The three helicopters flew back to the top of the stone mountain, and after Wu Haoming and his group all got off the plane, the three planes quickly flew back to Fansi City.

Since many biochemical ghosts just now have gathered in the place where the mutant died, the pressure on the position at this time has been reduced a lot.

But this is only temporary after all, and when the follow-up biochemical ghosts arrive, the pressure on the position will increase.

However, although there are a lot fewer biochemical ghosts in the attacking position at this time, the quality of the biochemical ghosts attacking now has improved a lot compared to the beginning, and almost every one of them has a high degree of evolution among ordinary biochemical ghosts.

In addition to a few extra pairs of bizarre spikes on his back, his speed and ability to resist bullets have also been improved a lot. And because its size is much larger than the ordinary one, a large number of corpses of this evolved body are almost piled up in front of the positions of all sides at this time, so that many bullets of the defenders at this time are hit on those corpses.

"It's not good!" Wu Haoming muttered as he looked at the front of the position through the night vision device.

"Well, Captain, is there anything wrong?" Bell looked at Wu Haoming suspiciously, the battle at this time had reached a white-hot state, and both sides had almost moved their full strength, and those huge mutants just now, in his opinion, should be the enemy's hole cards.

So when he heard Wu Haoming's words, he became puzzled.

"Go tell our people not to burn the corpses of those biochemical ghosts with Molotov cocktails, and if you feel too much, just blow them up. Wu Haoming said, his eyes looked at the back of the mountain, another defensive position in Fansi City, because there, at this time, there was a fire rising into the sky.

Mistaken, Wu Haoming thought as he said to Bell beside him: "Go quickly, inform the people in other positions not to use incendiary bombs, because after the body of this biochemical ghost is burned, it is very likely that it will produce a substance that is more terrible than the biochemical virus." ”

More terrifying...... Bell's heart was shocked, but his body had already acted.

"These monsters, look at them this time, aren't they arrogant!" A man with a machine gun in his hand and a half-burned cigarette in his mouth looked at the raging fire in front of him, with a smile on his face.

"It's still arrogant! This time they can't even keep the corpse, hey! Give me a cigarette ....... Another man, also with a gun, stood beside him.

The man with the cigarette in his mouth took out a box of cigarettes from his chest pocket with one hand, and just wanted to hand it to the man beside him, but suddenly his eyes widened, he covered his chest, and knelt directly on the ground.

"Hey, it's okay! Is it smoking too much!" The man who had just asked for a cigarette looked at him, but after a moment, he realized that something was wrong, and that this was definitely not a phenomenon of smoking too much.

"What's wrong with you, are you alright?"

"I'm ......!" the man was halfway through his words when a lot of scarlet liquid came out of his mouth.

Seeing this scene, not only the person who had just asked for a cigarette, but even the other people next to the man were stunned in place.

But before the people on his side could react, a few more people clutched their chests like the man, fell to the ground, and then vomited blood.

"It's all hopeless. Wu Haoming wore a special gas mask, looked at a large number of people on the ground who were vomiting blood, and secretly cursed himself in his heart for forgetting this!

When they were in Valkyrie, there was a mutant whose blood died when touched, and at that time, Wu Haoming's method of dealing with those mutants was to wrap his whole body and not touch it.

Later, the scientific team of the rescuer, after studying the samples they brought back, actually found that if the blood was heated at high temperatures, it would turn into an extremely terrible substance.

And compared to the mutant blood in a liquid state, this heated substance will turn into a substance that can be transmitted through the air, which is what is really terrifying.

"Captain, most of our men are wearing special breathing plugs and gas masks, and there are not many injuries, but the other positions are ....... Bell's blue eyes looked very sorry behind the lenses of his gas mask, but he couldn't be blamed for this, after all, this terrible substance that can be transmitted through the air was only seen once by Wu Haoming in Valkyrie.

The members of these teams of Van Si City or Saviors usually fight with some ordinary biochemical ghosts, and if there are powerful mutants, they will directly use large-caliber weapons to solve them, and the current situation will not occur at all.

"After the madness, it's time to get on the bayonet. Wu Haoming suddenly said a very strange sentence.

"Bayonet!" Bell listened in a fog, but he vaguely felt that the enemy's attack seemed to be more violent. Sure enough, after the bodies of the biochemical ghosts were burned in several defensive positions, and some people were poisoned and died one after another, the already crazy biochemical ghosts became even more manic.

This makes the various guard positions, which have become precarious due to the poisoning of many people, even more dangerous.

Although there are many defensive organizations that have taken out all the weapons at the bottom of the box, the biochemical ghosts attacking at this time are completely different from the original ones, and now they are attacking like a pack of hungry wolves, regardless of their own life or death, they just want to rush over, tear the enemy to pieces, and then swallow it.

Wu Haoming's group on the side of Stone Mountain is also working at full strength, and the members of the sniper team at the top of the mountain have also replaced their sniper rifles with the kind of guns that fire air bullets specially made by the rescuers.

Because this gun not only does not need to be reloaded, but also has extremely penetrating power, it comes in handy at this time.

The grenade team at the foot of the mountain also took out their weapons as family heirlooms.

The weapon, which could only fire one grenade at a time, was now bombarding a large number of cyborg ghosts in front of it like a Gatling gun.

Looking into the distance with a night vision device, Wu Haoming's heart had a bad premonition.

Now it is clear that the enemy's goal is 100% to capture the city of Van Si.

Although the enemy's attack method was not quite the same as he expected, the way the enemy arranged his troops from the beginning of the battle to the present was obviously thoughtful.

"There are already several positions that have retreated to the rear, and it seems that the fire just now has poisoned many of the biochemical ghosts. Bell hurried over, still wearing a gas mask on his head.

"Take care of ourselves! There are plenty of reserves in the city, so we don't have to worry about it. As he spoke, Wu Haoming still unconsciously looked at the electronic map in his hand.

This map is the map of the city and the surrounding buildings, as well as the positions established by various organizations, and the defense line, and at this time, several places on it that should have been defensive positions have been marked with large red crosses, and it is obvious that the people there have retreated to the rear, or have been wiped out by the biochemical ghosts.
