Chapter 472: Silent fight

"System, there is something wrong with the number of snails, why do they suddenly die so many?"
Liu Feng just didn't care about the number of snails. It was not until the buffer time could not make up for the loss of the snails that he found something wrong. His thousands of troops now only have a few hundred left, and the number is still declining.
[What you did not notice does not mean it did not happen. 】
The system suddenly said something meaningful, and immediately after a dozen snails were knocked to pieces, the scene spread into Liu Feng's head, and the scene was extremely tragic.
This time their snail shells have turned into powder, and with a light blow, they floated in the air, and they couldn't even leave a broken body.
It turned out that it was not that the work efficiency of these snails had slowed down, but that they were being killed silently and disappeared very quickly in places that Liu Feng could not see.
Liu Feng summoned other swarms of insects to help, and wanted to save the snails, but whether it was the quick-moving iron-toothed insect or the centipede with huge mechanical power, they were all broken.
The guy hiding in the chemical fog seemed to have no weakness. The more rescues Liu Feng launched, the greater the loss.
[You should take care of yourself first! ! ! 】
The system suddenly jumped out of a line and added three exclamation marks at the end, indicating that the situation is extremely critical.
Before Liu Feng had time to set up the defensive device, his nose was hit hard, and the pungent chemical smell filled Liu Feng's nose.
Those snail mucus actually didn't work anymore. Under the attack of this high concentration of chemicals, the thin filter net became useless.
"Cough cough cough!"
Liu Feng coughed a big mouthful of blood. He felt that those chemicals had penetrated into his lungs, wantonly destroying every blood vessel in him, and swallowing Liu Feng from the inside out.
He didn't have time to call for help, and even less time to stop him, he could only do things wantonly in his body.
At the same time, his head buzzed, and the roar that could only come from the zombie's body was piercing through his eardrums, and this sound was emitted from his body.
Liu Feng felt as if he was possessed by something, and his limbs and brain were out of control.
He suddenly had a very terrifying thought that the zombie had entered his body following the intrusion of these chemicals.
Liu Feng didn't know what kind of zombie had such a skill, but he would never allow a monster to live in his body.
He hurriedly summoned the snails with a very anxious expression. Now these snails are his only life-saving medicine. He put these snails to his mouth and let them transform at the fastest speed.
But he was too impatient, shaking his hand, and almost swallowed the snails into his mouth.
The concentration of these chemicals is much higher than that in the environment. Even snails of grade LV5 can't quickly convert these chemicals. Liu Feng's body quickly became out of control and fell directly to the ground.
The situation of Xiao Yun and Bai Youqing is also the same. They vomit blood, are unconscious, and seem to have no vitality.
"Woohoo!"
The environment around them gradually became noisy, and deafening roars came from all directions.
Liu Feng couldn't tell whether these sounds came from inside or outside of his body. He just felt that his head was about to be smashed by these sounds, and every roar made him a headache.
At the same time, his chest was violently hit, and the force seemed to crush his ribs and pierce every broken bone into his heart.
"Cough cough cough!"
Liu Feng tried his best to make the final struggle, his body became weaker and weaker, but at this moment the chemicals around them slowly dissipated, and a behemoth covered in mud walked out from behind the shelf.
His size is a bit higher than the giant zombies Liu Feng saw before, and the yellow mud seems to be attached to him irregularly. Even if it is knocked off by surrounding debris, it can still stick to it. Attached to another location.
In this way, the appearance of this behemoth is always changing. Every piece of yellow mud on his body is his armor, making it impossible to judge his exact position.
If he launches an offensive rashly, he may be confused by his appearance and fall into his applause.
Liu Feng could only pretend to faint first, wanting to see what kind of ability this behemoth has before making a decision.
But he soon regretted that he had adopted such a passive approach. When the behemoth kept getting closer, Liu Feng felt that he would be out of breath.
The peculiar smell of those chemicals came from this behemoth, and the closer he got to them, the stronger this suffocation.
Liu Feng knew that the skin and flesh of zombies were more tenacious than human beings, and many substances were unable to corrode them. Even if they were damaged to a certain degree, they could live without pain and without delaying their ability to move.
This is why many scientists did not want to eliminate all the zombies at the very beginning. They hope to find a way to control the zombies, so that they can become the strongest troops in the front line.
Even if the body has fallen apart, as long as the head is still there, you can continue to fight.
This selfish thought also caused humans to miss the best time to eliminate the zombies. Now even if they want to completely eliminate them from the earth, it is no longer possible.
But these zombies are not without any weakness. In addition to using external force to attack their brains and lose their ability to move, there is another method that is chemical shells.
Although the skin and flesh of zombies are strong and tenacious, they are not resistant to any chemical agents
If his whole body is covered with this high-concentration chemical substance, even zombies, their skin and muscles will gradually die away. Once the skull is corroded, his brain will not last long, and it will be within a few minutes. Corroded by these chemicals, it completely loses mobility.
But the guy in front of him, not only was not affected by the chemicals in any way, but also developed the ability to complement it, turning it into his own advantageous weapon.
Liu Feng now wished he could faint completely like Xiao Yun and Bai Youqing, so as not to be tortured here.
"You are finally here, I have been waiting for you for a long time."
This behemoth could actually speak, but after passing through the heavy yellow mud, his voice was a little fuzzy, and he couldn't tell whether it was a male or a female.
But Liu Feng still raised his ears, and at the same time flashed a large number of names in his mind. The reason why this behemoth said that meant that they must have seen it before.
