Large, large raindrops streaked across the dark night sky, hitting the blood-red dirt and splashing up grains of debris.

Thunder streaked across the hall, and everyone, including Zhou Duan, listened to Langton's story of their experiences as they quietly watched with their eyes fiddling with something resembling a genetic chain in a plastic bottle.

They still remembered that Zhou Duan had injected Natasha with this thing, and they had some longing in their hearts.

If they hadn't known that this thing couldn't be injected directly now, they would have wanted to grab it directly.

Of course, it's just a matter of thinking.

In a city that is still relatively well preserved, in a laboratory full of transparent capsules the size of a person and various instruments.

People in white coats shuttled back and forth.

The door to the laboratory was opened again, and a man in a senior officer's uniform walked into the middle of the laboratory, accompanied by several older-looking men.

There are test tubes with strands of genes in them.

"That's what you're doing?"

"Yes, Aemond, this is an incredible discovery." A man with glasses, black and white hair and beard picked up one of the test tubes.

This strange "precipitation" of life allows our research to transcend countless obstacles and directly retain the most essential source. ”

"Richie, get to the point." Wearing a military uniform, Aemond knew these old guys very well, although they were all at the top of their respective fields, but the essence of chatter had long been tempered in endless loneliness.

"Their role is to give the individual more strength and a longer lifespan, unlike the previous inferior genetic products that would shorten the lifespan of the test subject." Richie didn't pay attention to Aemond's interruption.

"Are there any side effects?" Aemond was a little excited when he heard this, but he asked patiently.

"At present, it seems that the demand will increase in some aspects, but there will be no out-of-control phenomenon, and other thermal weapons are the same, depending on the person's own quality.

Believe me, this is a gift from God, and you can't imagine the thrill we felt when we found this natural "finished product".

As long as some impurities are removed in a vacuum, it can be injected directly, and it does not even need to be removed, as long as there is a syringe, oral administration will lead to death, and the caliber of the syringe should also be customized. ”

"Are there no other restrictions?" Aemond was long past the age of being fooled by these old men.

"Absolutely." Several old men sneered.

But it's not a matter of the "spark genes", yes, we call them collectively the spark genes, and they will be the evolutionary spark of our human race.

As for limitations, there are a number of innate conditions that must be present in subjects that can be injected effectively, and we have found that a specific expression enzyme is required.

This enzyme is produced at the moment of cell division and disappears in a few minutes in the average person, this problem is not difficult to solve, and it is easy for young people or with some stimulation to achieve the condition.

The other is the need for sufficient genetic vacancies, in which males are more dominant, and we have not yet studied why there is such a difference between gene vacancies for X and Y.

But judging by the probability of the test subject, this is true.

The last one is the need for a transcriptase, and just as RNA needs a specific reverse transcriptase, these external genes also need a specific transcriptase, but that transcriptase doesn't really exist. ”

Aemond was a little confused, but still pretended to be calm: "What do you mean?" ”

"Because it only combines into enzymes when it encounters specific external genes, usually it is just ordinary proteins or other substances."

"So how do you know if there's such a transcriptase?"

Richie gave Aemond a thumbs up: "That's a good question, we don't know, but there is a solution, which is to find this substance through continuous experimentation, and then help the human body to transcribe it by taking relevant foods or injecting this substance."

But this kind of thing is too wasteful of resources, and there is no possibility of promoting it at present. ”

Edmond knew that this method was meant for those above, and nodded: "So how many of these reagents can my army receive?" ”

Rich suddenly became a little shy: "You also know, now those monsters outside are getting more and more powerful day by day, and we have to supply five military regions, so ...... Ten sticks? ”

……

"There was a big tree in our town, which completely blocked the sky, and there were many bees on the tree, which killed many people, and no one escaped except us." Langton didn't speak calmly.

"Then on the way, we met a huge black wolf, a few people died, we killed it, and then we found the ......" pointed to the gene chain in Zhou Duan's hand.

"What's the use of this?" Langton looked at the crowd.

"Maybe it's a gift from God." Rhona didn't answer directly.

“……！”

"What's going on?" Hearing the sound from the ward not far away, even Langton became a little impatient.

Zhou Duan put the prototype gene into the storage, and he decided to check it out because of his caution.

Before they could get there, a few people suddenly staggered out of it.

"There's a dog, and the dog is coming in from the outside." The men were a little flustered.

Zhou Duan thought to himself that he hadn't heard the dog bark, and a few dogs wouldn't be.

But he soon understood, and several "zombie dogs" with only a few pieces of flesh hanging from their bones rushed towards him.

"Bang!" A bullet passes through the head of a zombie dog.

But it didn't do anything other than make the zombie dog even more mad.

Just as Zhou Duan was about to make a move, the glass in the living room was suddenly shattered.

"Go upstairs." Zhou Duan gave up the pistol and smashed the head of a zombie dog with an axe, saying to Elena and them.

Ignoring Langton, who was a little caught off guard, several zombie dogs rushed into the living room.

There were a lot of obstacles in Elena's way, but with Natasha, Elena and the Les brothers in front of them, there was not much danger.

Langton's side was different, and their attack on the zombie dogs was a little difficult to parry.

The white father and son actually fled into the middle circle of Langton and the girls in their protection team in the chaos.

The defensive circle, which was originally missing a mouth, was instantly invaded by zombie dogs.

"Help us!" Seeing that Zhou Duan seemed to have some strength left here, Langton hurriedly called for help.

Their guns are an ornament at this moment.

Zhou Duan didn't go over, just shouted: "Run to the back, go upstairs." ”

At this moment, he was a little glad that he had let these people in.

In Langton's battle circle, the white father had been bitten by several black dogs.

Several of the blacks around him ignored him, instead guarding against the black dog he had just found with a stick.

He could only look helplessly at his son.

But the son had already rushed to the side of the stairs in a panic.

At this time, a larger zombie dog pounced out of the ward on the side and directly grabbed the son with his mouth.

Langton looked at the big black dog blocking the back road with some despair.

Zhou Duan saw that Xavier and they had already gone upstairs, and he was not worried, these zombie dogs were estimated to be the same as those before.

It seems that the vocal cords have been damaged, and Zhou Duan has not heard these zombie dogs bark.

The biggest dog didn't stare at Langton's men, but ran straight towards Zhou Duan.

In fact, it is also very easy to understand, after all, there are three or four corpses around Zhou Duan, whether it is a ghost-faced insect or a zombie dog.

"Run!" Langton looked at Zhou Duan nervously, but the people on the side didn't care about this, they quickly seized the opportunity to run upstairs.

Langton only reminded him out of kindness.

Zhou Duan picked up the fire axe, missed the rotten teeth of the large zombie dog, and cut it down with an axe.

But what Zhou Duan didn't expect was that the head of this giant zombie dog flew out of the air with a black shadow the size of an arm.

"Listen to the wind and thunder!"

Zhou Duan, who didn't have time to shoot again, had to use this trick.

The thunder and lightning flashing in the wind and rain outside seemed to have been extradited indoors.

The movement of the black shadow came to an abrupt halt and fell to the ground, almost in no particular order as the corpse of the zombie dog.

It's just that Zhou Duan was a little surprised that a prototype gene actually appeared in the ghost-faced insect that turned into charcoal.

And it's red.

took out the storage device and quickly put it in, Zhou Duan's face was not happy because of the death of this zombie dog, but even heavier.

It was raining heavily, and the rain line drifted in with the strong wind, but these zombie dogs were completely dry.
