Xu Xian'an was still staring ahead, his expression was a little cold, and he didn't speak.

"When I came out of the ground, I remembered something. I remembered that three years ago, I reported to the headquarters at that time several abnormal incidents in Xiangcheng, and I suspected that something might be wrong with Liuxin. But the reply from headquarters was delayed.

I also remembered that I heard people say that after being infected, most of them will mutate into high-level gray ghosts, and there will be a small number of them, who have not mutated, and are still normal people, but their realm has been greatly improved. If Ryushin is the source of infection, the effect on all aliens should be the same, how can it produce diametrically opposite results? And this difference has no regularity, just a probability.

Moreover, this virus seems to be specifically targeting xenomorphs, and the first generation of infected people known to be all xenognores. Human beings are indirectly infected.

I thought, if the source of infection is not Ryuxin, not from nature, but from human society. So who and which group will have the strength, the technology, and the motivation to create such a virus, or will it be just a potion in the first place, which may either make the xenos jump in combat power or cause the xenos to mutate into gray ghosts?"

Xu Xian'an no longer had any expression on his face.

Lu Weizhen continued: "I also think of one thing, there are two places where there are currently the most high-level abilities. One is Lin Tian, who is nourished by the power of Liuxin, he himself is a big six five, and he also has six super green dragons, and there are countless big green dragons. It's just that now, we've all killed them.

There is another place, which is the Grand Commander. I remember three years ago, there was no Super Green Dragon in the whole Greater China region. Three years have passed, and my mother, who used to be the No. 1 in Greater China, is still only a big green dragon. But since when has the Great Commander led any of the guards around you to be a super green dragon?

Commander, tell me, is this disaster, this war, a natural disaster or a man-made disaster? Is it that we xenomorphs are unlucky enough to encounter a change that has not been seen in Ryuba for a thousand years, or is there someone else to blame? Is there anyone who should be fully responsible for this incident?"

Her gaze finally returned to Xu Xian'an's face, but she saw that for more than 20 years, in her memory, there were tears rolling silently on the face of the commander who had never been resolute and sophisticated.

He wiped away his tears, still red-eyed, looked straight ahead, and said, "That project was launched eight years ago, and human trials began five years ago. The experiment used volunteers among xenomorphs and condemned prisoners. As a result, only a few people have made the leap in ability, some have not changed, some have died, and some have become what we now call gray ghosts. Realizing that the agent was not yet mature and the consequences were uncontrollable, we immediately stopped the experiment. We also noticed that the Grey Ghosts were very contagious, and immediately imprisoned all the Grey Ghosts to prevent the spread of infection.

However, we didn't expect that various places began to report abnormal attacks by aliens or aliens, including your Xiangcheng. At first, we didn't tie the two things together. Later, there were more and more riots, more and more abnormal, and even gray ghosts began to appear in the outside world. Our scientists later analyzed that it should be in our hands, the respiratory and energy circulation systems of the first batch of infected people and Ryuba induced each other, the first to infect Ryuba and Ryuxin, and then Ryuba in turn, first infected the nearest alien with weaker resistance, and then Xenomorphs and humans.

No one thought that the virus would spread in this way. By the time we reacted, it was too late and we couldn't stop it. ”

Lu Weizhen was silent and said, "It's so important to get a super-high-level xenomorph? Sixth Five-Year is so important? I can't wait to recover Lihuang's strength, so I can't wait, so that you are willing to take such a big risk?"

Xu Xian'an smiled and replied: "Really, you, Uncle Xu, and I have been working hard to achieve this goal all my life." If you ask me if I don't regret it? I regret not controlling the consequences of the experiment, I regret that I know little about the mechanism of Ryuxin's operation and lack of precautions, but I don't regret my persistence in this life. The galaxy is so big, maybe there are more civilizations, and there are higher civilizations than the old ones. And I Lihuang is still under the fence, living with the earthlings as a vibrant race, living together on the narrow planet with limited resources. The law of the jungle eats the strong, and maybe one day, the catastrophe will come. Maybe from earthlings, maybe from outer space civilizations. As the Great Commander, all the efforts I have made are to make the flame of Lihuang's life continue forever and forever. I did make mistakes, and I and the leaders of Greater China made unforgivable mistakes. But if the same opportunity is put in front of me again, I am afraid that I will still choose to take risks. ”

In Lu Weizhen's mind, he flashed through the wormhole and walked out of the figures of the five men in black. In front of them, even Da Liuwu is like a puppet and has no power to fight back.

After Lu Weizhen was silent for a moment, he asked, "What about the purification of Liuxin's heart this time? Is it really necessary? Or is it just a scam? Do you make a show to cover up your mistakes? Do you know what we have lost? Do you know what I have lost?!"

Xu Xian'an took a deep breath, his eyes were red, and replied: "It's not a show, it's not a scam." Purifying Ryu's heart is indeed able to reverse the ability of the infected. It's just that I didn't expect that Lin Tian would have taken Liuxin for himself a long time ago, and you would meet him. ”

Both were silent for a while.

Lu Weizhen saw Xu Zhiyan's hairy head at a glance, and looked away.

She asked, "How?"

Xu Xian'an smiled, he stood up, and said, "I have thought about this a long time ago." I can't die yet, because I'm still at war, and I can't leave everything I have in my hands. When the war is over, or when a cure and a vaccine are developed, I will give you, and to everyone, an account. Don't worry that I'll get away with it, who can escape from the hands of Admiral Six-Five?"

With that, he strode towards the door.

Lu Weizhen looked at his back.

Xu Zhiyan also tilted his head and looked at his back.

As soon as Xu Xian'an walked to the door, Zhu Tangting strode over, followed by three super green dragons with blue noses and swollen faces. Seeing Lu Weizhen in the house, the four of them stopped outside the door and didn't dare to take a step forward.

Zhu Tangting said: "Great Commander, it's not good, Lin Tian is dead, and the 30,000 gray ghosts in Guicheng, under the leadership of a left-behind super green dragon, went to Xiangcheng overnight and defected to the commander of the gray ghosts in Xiangcheng." Now, their vanguard has reached the border of Xiangcheng and is about to storm the human army's defenses. ”
