After a short cheer, they quickly cleaned up the corpses that covered the road, and then let go of the defensive ring surrounded by cars.

"Little brother, if you hadn't helped this time, I'm afraid we would all have to fold here, and we can't repay the grace of saving lives!" Cui Jian, whose face was a little pale, stretched out his right hand towards Duan Fei and said with a sincere expression.

His physical strength was too exhausted, and his body was so weak that he needed help from others to stand firmly, but his face was always filled with a happy smile.

"My name is Duan Fei, you should be the escort of the refuge!" Duan Fei smiled slightly and shook Cui Jian's hand.

"Do you know who we are?" After hearing Duan Fei's words, Cui Jian was slightly stunned, and a look of doubt flashed in his eyes.

Duan Fei smiled slightly, nodded, and said: "Yes, in fact, I am not alone, with me, there is a team of soldiers like you, their captain is called Cao Silong, I think you should know it!" But I came alone, and they were hiding not far away. ”

"Lao Cao, of course I know!" As soon as the words fell, Cui Jian exclaimed, and a look of surprise suddenly appeared on his face,

Cao Silong was one of the few friends he had in the army, and it was undoubtedly a surprise to meet Cao Silong here.

Looking at Cui Jian's surprised look, Duan Fei smiled faintly, and then slowly told the ins and outs of everything.

From his encounter with Cao Silong, who was besieged by zombies, to the assassination they encountered, to the fact that they finally learned about the accident of the escort team, Duan Fei was simple and concise, and soon finished telling.

Listening to Duan Fei's words, Cui Jian's heart suddenly swelled up, and a gloomy look slowly surged on his face.

"So that's the case, that's really a coincidence, but you said that on the way, someone came to assassinate Lao Cao, is this true?"

"Yes, if you don't believe me, you can ask him yourself when they come." Duan Fei nodded and said.

After finishing speaking, Cui Jian nodded, a faint look of anger flashed in his eyes.

The struggle between Commander Luo and Guan Zhonghua has long been no secret among them, but what he didn't expect is that the struggle for power in the army has reached such a point now, and now even an important army official like Cao Silong has someone who dares to blatantly design an assassination, and he really can't imagine what the army will become in the end if the current trend continues.

However, these thoughts only welled up in his heart, and Cui Jian did not say it.

After a few more polite words, Cui Jian hurried back to sort out the remaining materials, vehicles, and the placement of those important scientists. And Duan Fei also took advantage of this time to bring Cao Silong and them back.

It didn't take long for Cao Silong and the others to join Cui Jian and them under the leadership of Duan Fei, and when the two teams met, everyone was overjoyed, and they were happier than anything else to meet their comrades in such a situation.

But when Duan Fei came back, the scene in front of him immediately attracted his attention.

I saw that most of the zombie corpses that were originally scattered all over the place had been gathered together, and several soldiers, under the command of an old man in a white coat and gray hair, were using daggers to dissect the corpses of the three mutant zombies, as if they were looking for something inside.

Beside the gray-haired old man stood a tall, cold-looking beauty, and in her hand was a tray, in which was placed a transparent crystalline object that emitted a faint fluorescence.

The moment he saw this crystalline object, Duan Fei's eyes froze, and a look of surprise flashed in his eyes.

"Gene nucleus!"

The gene nucleus is a special energy crystallization condensed in the zombie corpse after the energy emitted by the source species is collected, and it is also the source of the ability of the mutated zombie.

In the next generation, it is already a consensus that there is a gene nucleus in the mutant zombie corpse, but now that the apocalypse has just passed, human beings are not aware of the existence of the gene nucleus at all, but judging from the current situation, the existence of the gene nucleus that the old man in front of him has obviously discovered, what is going on?

Just when Duan Fei was wondering in his heart, those soldiers had already finished dissecting the three mutant zombies, and judging from the current situation, they didn't seem to have found what they had in mind.

Looking quietly at the three strangely shaped corpses in front of him, a look of confusion flashed in the gray-haired old man's eyes.

According to his research, these three mutated zombie corpses should have such a transparent crystal, but when he dissected the corpses of these three zombies, only one corpse was found in the crystal, and the other two were not found at all.

It's simply not going to happen!

However, the picture in front of him made him have to believe that in the other two corpses, there was indeed no crystalline body he wanted.

"Teacher!" Looking at the tangled look on the old man's face, the tall beauty beside him couldn't help but shout.

Hearing the voice of his student, the old man sighed and said, "It seems that I still think too simply, this special energy body is an incomparably wonderful thing, my previous idea should be wrong!"

As he spoke, the old man shook his head and slowly left here with his hands behind his back.

This old man is actually a top scientist, and after the outbreak of the apocalypse, he devoted himself to the study of this virus in order to save mankind.

Under the protection of his students, he hid in the underground research room of Qinchuan University during the time of the Apocalypse, and in these few days, he did a lot of research.

At the beginning, no matter how hard he tried, he was at a loss for this virus, and he never thought of an effective way to treat and restrain this virus until the appearance of mutant zombies.

After the apocalypse, an experimental zombie he captured suddenly mutated, and later he found this special energy crystal from this mutated zombie, and from this crystal, he was pleasantly surprised to find the possibility of restraining the virus.

Such a discovery immediately made him overjoyed, and then he completely devoted himself to the study of this energy crystal, and in the following research, he found that like this energy crystal, it usually appears in those mutated zombie corpses with abilities, so the scene in front of him appeared.

Later, his students made contact with the army by radio, and after consulting with the army, they decided to leave Qinchuan University and go to the army.

After all, although they were relatively safe in the underground research laboratory of Qinchuan University, they were far from being protected by the army. Moreover, the location of Qinchuan University was close to the city center, and if they were found one day, he would have no chance of surviving, so he chose to go to the shelter.

The absence of the energy crystals made the old man fall into depression for a while, and he thought that his research had gone wrong, and the conclusion that there was such a crystal in every mutant corpse was actually wrong.

If the thoughts in the heart of this elderly scientist were known to Duan Fei, Duan Fei would definitely be a little crying and laughing.

In fact, this old man, his conclusion is correct, there is such an energy crystal in the body of every mutant zombie. The genetic nucleus is the fundamental reason why they begin to mutate and evolve, and without the formation of this genetic nucleus, zombies will not mutate.

However, in the battle just now, because of Duan Fei's ability, the mutant zombie with the electric ability and the last mutant zombie with the madness ability were devoured by Duan Fei, so they only found the gene nucleus from the mutant zombie that was killed by Cui Jian, and found nothing from the other two mutant zombies.

After collecting the collected piece of gene nucleus, accompanied by Cui Jianhe's soldiers, Duan Fei and Cao Silong met with these scientists.

"Elder Jiang, this is called Cao Silong, he is a lieutenant in the army, this is the Duan Fei Duan brother, he is the one who saved us all......" Cui Jian patiently introduced to the old man while pointing at us.

"Hello, hello!"

Under Cui Jian's introduction, the old scientist also greeted everyone one by one with a smile on his face. However, when facing Duan Fei, a faint look of gratitude and admiration flashed in the eyes of the old scientist.

The picture of Duan Fei's battle with those zombies just now is still vivid, and the powerful figure has been deeply reflected in the scientist's heart. Although he was a top biologist, he was also an ordinary human being, and he knew how to be in awe of a strong person like Duan Fei.

"Fortunately, Little Brother Duan came to help, otherwise, my old bones would have to be confessed here!" As he spoke, the old scientist laughed, held Duan Fei's right hand tightly, and said, "Hello, contemptible Jiang Tianxin!"

"What, Jiang Tianxin!"

The moment he heard the old scientist's voice, Duan Fei's body trembled violently, and a look of extreme shock flashed in his eyes.

"Jiang Tianxin, Professor Jiang! So that's it! ”

Duan Fei muttered to himself in his heart, and his eyes finally showed a look of sudden realization.
