The huge roar of the helicopter propeller had already been heard, Wang He took Laifu and Wangcai to the tarmac to prepare to board the plane, originally these two guys should have been taken away with Black Hawk, but Wang He didn't leave, and the two of them couldn't live or die in the helicopter, so they had to give up.

I'm about to leave, I don't know if I can come back, Wang He glanced at the valley with some nostalgia, this is the first base in the real sense, and it is false to say that he is not nostalgic.

"Boom!" Just as the helicopter was about to land, it suddenly skewed out of control, and under the gaze of everyone, it crashed into the valley and exploded.

"It's a bat!" Someone pointed to the air, and at some point countless black shadows shuttled back and forth in the air, and the explosion of fire was reflected in the sky, and the dense black shadows shuttling back and forth were bats.

"Ah...... Help!" A large number of bats swooped down, and several soldiers who had no time to dodge were crawled all over their bodies by bats, and the soldiers only had time to stretch out a hand helplessly forward, and then there was no sound.

"Quick! Go back, hide indoors."

Wang He drew his knife and swung it, no matter how fast the bat was, it was difficult to get close to Wang He's body, but there were too many of them, Wang He could barely protect himself, but he couldn't keep so many people.

Fortunately, most of the people withdrew to the laboratory, and those who didn't have time to run fell to the ground, reduced to dried corpses.

Wang He was the last to rush into the laboratory, and as soon as he entered, the others rushed forward to smash the door to death, but despite this, a few bats got in, and it took a while to solve it.

"Fatty! We were attacked, the helicopter crashed, and now in your lab." Wang He contacted Li Chenyang as soon as possible, and it was obvious that the reconnaissance was wrong and the evacuation failed.

"How is that possible? As a result of the drone reconnaissance, the mutant birds have stopped advancing, most of the mutant beasts have slowed down, and only the mutant rats are still approaching Tiger Mountain, and it will take an hour at the earliest...... What happened to you?"

"Bats! Lots of bats!"

Wangcai tore up the last bat, Wang He picked up a filing cabinet and blocked the door, and everyone took a few steps back, staring at the door, their faces full of panic.

"It's my mistake, these bats can't be observed with thermal imaging...... Li Chenyang's voice was full of guilt, but the matter has come to this point, regret is useless, find a way to remedy it.

"Zhang Xingkai is ready to go, you hold on a little longer." Wu Ting cut through the channel and said quickly.

"No! The helicopter can't get close, and when it comes, it's in vain." Wang He immediately vetoed it, no matter how good Zhang Xingkai's driving skills are, he can only end up in the same fate in this bat swarm.

"But ......"

"No, we'll figure it out ourselves." Wang He interrupted Wu Ting's words, and when he heard her uncontrollable cry, his heart softened, and he said softly: "Don't worry, I haven't seen any scenes, it's just a few bats, keep your home, wait for me to go back."

Wang He patiently persuaded him, and Wu Ting also knew that the situation was urgent, so she reluctantly told a few words, and then hung up the call.

"Commander, fourteen people are dead, and forty-nine people are still ......" Guan Hongfang saw that Wang Hetong had finished speaking, and leaned forward and whispered, "There is no food or water here, we can't hold out for long, what should we do?"

Guan Hongfang has already been scared to the point that his legs are weak, his courage is notoriously small, although he has recently become an official and has seen a lot of the world, but he is the first person to be coaxed in this situation, and the staff of the Political and Legal Department under him are similar, not much better.

The location of this laboratory is close to the entrance of the valley, because it is afraid of fire and other reasons, so it is far away from the crowd gathering place, and it is only fifty or sixty meters to rush out of the valley, but rushing out of the valley does not mean that it is safe.

In the eyes of bats, humans are a delicious and juicy buffet, much easier to deal with than zombies, and there are probably very few of the remaining forty-nine people who can rush out alive and return to Genting Mountain.

Of course, Wang He definitely has that strength, his strength is strong, and his speed is faster than others, killing all the way, others will only be a tool for him to delay the bat.

And these people also know very well that they plan to do the same, even Guan Hongfang is ready to die, and he pulls the king

He, despite his legs trembling and stumbling in his speech, still firmly spoke his heart.

"Legion Commander, after the cataclysm, I have suffered enough, suffered a lot, and finally was taken in by the Divine Arrow Legion, these days I feel that every day of my life is earned, and I am fortunate to work for you, and I have no regrets in this life.

I, Guan Hongfang, am cowardly and cowardly, and it is impossible to kill the enemy bravely, but it can be regarded as two taels of flesh and blood, so I will use this flesh and blood to open the way for the legion leader, the legion can do without us, but it must not be without you, the legion commander! You must live!"

After speaking, Guan Hongfang was about to rush out, and the rest of the people also got up one after another, not to stop him, but to die with him, to buy time for Wang He to escape.

Wang He stepped forward and hurriedly stopped, his strength was comparable to these people, and he stopped him in a few clicks.

"Legion Commander! Indecision is a taboo for those in power! Let us die!" Guan Hongfang burst into tears, which provoked everyone to follow and persuade him, Wang He was upset by crying, and shouted: "Quiet! Listen to me!"

Everyone immediately fell silent, only for the occasional sob, and then Wang He said, "I believe in your generous determination to die, but this does not guarantee that I will definitely escape, Yunding Mountain is more than twenty kilometers away, and it takes two and a half hours to walk at my speed.

Even if I escaped the bats with your lives, who can guarantee that I will not encounter other dangers in these two and a half hours? Besides, the danger of Tiger Mountain today is the danger of Yunding Mountain tomorrow, and the solution to find a solution is still in this Tiger Mountain."

"What do you mean...... The warehouse?" A veteran asked uncertainly, he was a soldier who had been stationed in Hushan before, and although he couldn't say everything about the things in the warehouse, he probably still knew a little about what was there.

"Yes! There is only one chance, and if we succeed, we will destroy the bats and leave safely, but if we fail, Tiger Mountain will be completely blocked and will never be opened again, and then we will listen to you, we will rush out, how about it?"

Big guy, you look at me, I look at you, they all nodded in agreement, there can be a glimmer of life, who doesn't want to live.

Since they all agreed, Wang He didn't talk nonsense, if he wanted to open the door, he first had to know the password, although the work of cracking the password continued, but the progress was not great, and so far he had only guessed two numbers, which had to use the ability to deduce.

The deduction needs a large amount of evolution stock solution to support, Wang He rummaged through his pocket, there was only one bottle of evolution stock solution, and he searched through the entire laboratory and found no excess, so he had to call Li Chenyang on the walkie-talkie again.

"Fatty! Which of your labs still has the Evolution Solution?"

Li Chenyang didn't think much about it, thinking that he was ready to break through, and he needed to evolve the original solution just in case, and recalled for a long time and said: "No. 4, No. 4 laboratory, the original place where the silver eggs were placed, although the silver eggs have been moved to Genting Mountain, there are still some liquid leaking from the silver eggs that are stored there."

The effect of those liquids is even better than the evolution essence, it is extremely pure energy, but what side effects there are have been unclear, and at this time, there is no need to care so much, Wang He is ready to take a risk.

Laboratory No. 4 is not far away, on the other side of the valley, the oblique past is about a hundred meters, Wang He originally meant that he could just go over, but the others disagreed, forty-nine people rummaged through the laboratory, and finally made more than forty torches.

These mutant bats are afraid of fire, and when the helicopter explodes, the bats that were shot by Mars instantly turned into a small fireball and fell to the ground with a scream, so everyone planned to use torches to rush over.

Holding the torch, everyone looked at each other, gritted their teeth, nodded suddenly, Guan Hongfang opened the door, and shouted in a nervous voice: "Rush!"

More than 40 people rushed out with a "boom", waving torches in their hands as they ran, completely ignoring whether they would burn people, and a few of them were too close to their companions, their hair and clothes were set on fire, and they didn't care about extinguishing the fire, so they just rushed forward.

Wang He was squeezed in the middle of the team, and occasionally saw a companion with a fire and wanted to go up to help, but was pushed away by the people next to him, so he had to continue to run forward, and the bats were forced by the torches to not dare to approach, and groups of people kept circling around the crowd.

A soldier accidentally fell,

Before standing up, the bat was given an opportunity to take advantage of it, and the bat did not dare to approach the upper body close to the torch, and tore at the legs, and the soldiers were ruthless enough, so they directly put the torch on the leg and set the clothes on fire.

The body of the bat was a point, and in an instant, all the bats on the soldier's body were burned into fireballs, and they all died in the soldier's painful cry.

Wang He really couldn't bear to look at it anymore, so he rushed to the front with the strength of his feet, kicked open the door of Laboratory No. 4, and everyone rushed in, and then blocked the door in a panic.

Forty-nine people, in just a hundred meters, five more died, and the rest had varying degrees of burns, one of which was bitten by a bat and dragged in by Laifu Shengsheng.

Except for Guan Hongfang, no one else is an ability, even if they use the evolution essence, it is useless, but it will cause them to mutate, so they can only endure the pain.

Wang He told them to take a break, rummaged through themselves, and finally found a thermostatic refrigerator in the depths of Laboratory No. 4, which was filled with two layers of potion bottles, filled with silver liquid.

Opening a bottle, Wang He tasted it, it was similar to the evolution essence liquid he usually used, and the effect was even better, so he called Guan Hongfang over after making sure there was no problem.

After giving some instructions, Wang He sat down cross-legged, closed his eyes, sorted out his emotions, and entered the world of calculus.

Thousands of pictures appeared in front of him, but they still weren't all displayed, each picture was deducing a combination of a set of numbers, and after failure, it was replaced with a new set of numbers.

In reality, Wang He's body quickly dried up, Guan Hongfang didn't dare to hesitate, picked up a bottle of medicine and poured it into Wang He's mouth, with the infusion of the medicine, Wang He returned to its original state, but it didn't last long, and it dried up again.
