[With the passage of time, Li Degao and others have fallen into a bottleneck, and there is no way to study the new serum......]

Su Qi saw that they were about to scratch their bald heads, and the research on the new serum had failed many times.

In the laboratory, Li Degao stood in front of a microscope, looking extremely distressed.

The right hand subconsciously grabbed the hair, and as he let go, the hair fell to the ground, and the amount of hair on the top of Dr. Li Degao's head became more and more thin.

"Why do you always fail?"

Li Degao muttered to himself.

After a period of time, they found that the development of serum was difficult, like going in the wrong direction, and the experiment always failed.

At this moment, his assistant Chen Bing hesitated a little and tentatively suggested, "Doctor, I feel that there is something special about those giant zombies, why don't we try it and see if we can find a breakthrough from them?"

As soon as the words fell, Dr. Li Degao lit up slightly.

[The suggestion of the assistant Chen Bing was approved by Dr. Li Degao, and not long after, a giant zombie was transported into the laboratory. 】

[With continuous research, Li Degao and others discovered the secret hidden in the corpse, and there was a breakthrough in the research and development of serum......]

"The energy contained in its body......"

Dr. Li Degao and others stood in front of the microscope with a look of amazement.

The energy in the giant zombie corpse is much higher than that in the superpower and the ordinary evolution zombie, and the two are not the same level at all, and even the genes have some changes......

Dr. Li Degao's eyes lit up, and the light flashed in his mind.

[After three months, they are getting closer and closer to success......]

[Time passed, another six months passed......]

The picture flashed quickly, and the scene stayed for more than six months, and the situation at this moment has not changed much, and it is still maintained in the weakness of human beings.

"A new meteorite carrying an unknown factor did not appear."

Su Yun thought.

Because of the lack of the help of that meteorite, although the zombies in this society are still moving towards the goal of the third evolution, their efficiency is greatly reduced, and they are far from having the intention of completing the third evolution.

The chime continues.

[On this day, after a long period of research, Li Degao and others finally developed a new serum ......]

At night, the lights in the laboratory of the Hope Base were bright, and the scene inside was also taken into Su Qi's eyes.

At this time, a group of scientific researchers gathered together, looking extremely excited, staring at the five men in military uniforms.

"How does it feel?" Dr. Li Degao asked.

Hearing this, a middle-aged man with a scar at the head felt the energy surging in his body after drinking the new serum, his eyes couldn't help but light up, and he said, "It's very powerful!"

The others shook their heads.

"I seem to have failed?"

"Me ...... too"

After some inquiry, they found that only Chen Chen succeeded, and all the others failed to break through.

Although Li Degao and others had expected it, they couldn't help but be a little disappointed.

Dr. Li Degao thought, "But it's a good thing that someone succeeds, and the success rate of the serum will be found later." ”

He said, "Let's go to the clearing." ”

A group of people came to an empty and flat field with anticipation.

"Let's get started." Dr. Li Degao commanded.

A short soldier smiled, "Brother Chen, come on!" ”

The scar-faced man Chen Chen nodded, and then strode forward.

A large flame rose from his right hand, and then he waved his right hand.

Rumble!

A pillar of fire more than two people tall plowed forward.

The red light reflected, the heat wave came to their faces, and everyone subconsciously raised their hands to block it.

The hot air made them feel like they were sweating.

It's so hot!

They were terrified.

Then, when everything had subsided, they looked at the scene and couldn't help but take a small breath.

A target seven or eight meters away has long since disappeared, and the steel frame that erected the target will be red, melted and deformed!

"Reached the melting point of steel in a short period of time?"

Everyone was stunned.

That's at least 1,500 degrees, right?

This is still burned steel, if it burns people?

"That's amazing!"

"Brother Chen, you're so strong!"

The four military teammates exclaimed.

High altitude.

Looking at the scene below, Su Qi was a little surprised in his eyes, "Did you succeed?" ”

Next, he saw Li De et al. and others do some experiments, and found that the power of the improved superpower is far greater than before the improvement, at least three or four times more improved!

The most obvious thing is that ordinary superpowers can only cause a little skin injury against giant zombies, and they will be recovered quickly, but the improved superpowers are different, they can cause a large number of injuries, and they are already qualified to defeat.

For the sake of convenience, they call the upgraded superpowers second-level superpowers, which correspond to the second-evolution zombies.

The new serum is called the Evolution Serum by them.

It's just that when it comes to serum chances, there are some problems.

"The chance of evolution is only more than 100 percent?"

Su Qi looked at their research data and couldn't help frowning.

If for all mankind, this success rate is naturally nothing, there are always a large number of superpowers who have successfully evolved, but for individuals, it is not very wonderful.

Although he is the emperor of Europe, this non-chieftain serum obviously cannot satisfy him.

"You have to take care of the non-chiefs, and you can't make them despair, so let's wait."

Su smiled, and decided to wait for the chance of the Evolution Serum to be improved before using it, lest those non-chiefs feel hopeless and collapsed when they knew that he had succeeded once.

It didn't take long for Su Qi to see that Li Degao and others did not stop, and sure enough, they started to study again, obviously the current results did not satisfy them.

It may be possible to deal with zombies, but it should not be enough to deal with the hidden black hand, they are very careful and vigilant.

Then Su Qi saw that they were actually ready to continue to develop the Evolution Serum, trying to pile up their superpowers to the third level!

A tone appears.

[While you're thinking, it's another two months ............]

"Is progress slow?"

Su Qi saw that Li Degao and others were a little stuck in a bottleneck, which was also similar to the predicament last time.

"It seems that if there are no third-level zombies as test subjects, it will take a long time for them to research a stronger evolutionary serum."

It's just a little different from last time, with the second-level zombie as the blueprint, although the research and development of a stronger evolutionary serum is a little slow, the research progress is still moving forward at a speed that is not fast or slow.

It doesn't seem clueless like last time, and the speed of research is the same as not.

[During the research and development process, relying on a large number of research on second-level zombies, Li Degao and others improved the effective probability of three kinds of serum......]
