The starry sky pattern in front of him is constantly rotating and changing, making people feel the urge to be in it, this is the first time for Qin Lang, so close to the starry sky, that kind of realism makes Qin Lang deeply immersed in it.

"It's shocking, when Bai Chenxin saw this, he was even more excited than you, and he was stunned for at least ten minutes, this is the meaning of the existence of our discipline."

Lin Xuan's voice echoed in his ears, directly waking up Qin Lang, Lin Xuan signaled, Qin Lang and Lin Xuan sat on the futon, quietly looking at the changing and rotating stars around them.

The constantly changing projection of the starry sky was soon replaced by countless portraits, and under each portrait, there are lines of text, which is their life experience.

Looking at the costumes of portraits, it is not an age, it should be a researcher of all generations, the earliest can be traced back to more than 100 years ago, and the portraits are old and young.

Lin Xuan's voice sounded faintly, "You're right, these are the history of extraterrestrial civilization and human survival, it has a history of 130 years, for convenience, this discipline is called geosurgery to the outside world, and it has been passed on to me, I am the 12th generation inheritor." ”

At this moment, Qin Lang understood the value and significance of earth surgery, although the earth was very small and even humble in the entire galaxy and even the universe.

But the earth is fortunate to have intelligent creatures like human beings, but it is fragile, the universe is so big, and a civilization that is more powerful than human beings must exist.

According to the law of the Dark Forest, once humanity is discovered, destruction awaits it.

Although weak, there are always a group of people who use their wisdom to find a way out for the future of mankind, and among these people, a considerable number of people have spent their lives and finally studied things that cannot provide half of the substantive effect.

But they still have no hesitation, this is a kind of faith, it is worthy of respect, even if they do not see the results in their lives, they are worthy of heroes.

More than a hundred years of hard work have now all gathered in this house, and Qin Lang has been unable to calm down for a long time.

Lin Xuan's voice continued to sound. "Qin Lang, I know you have a knot in your heart, although you don't say it, but I know that you hate to treat people, even if they are your own students, as a chess piece because of a test, in order to find new students, even if the process will kill people."

"You must be thinking in your heart that I am cold-blooded, even if my own high-footed Xiangye dies, Liu Qingge is sentenced to life, I, as a teacher, have no trace of grief and show indifference, right."

Qin Lang was stunned, he didn't answer, and was silent for a long time, which was equivalent to admitting what Lin Xuan said in disguise.

Xiang Ye's death and Liu Qingge's sentencing were indeed self-inflicted, but how to say that the two were also Lin Xuan's students, and they were still the closest students.

Changed to Qin Lang, his own high feet, either died or betrayed himself, even if he was not sad, he would be sad, and he would definitely not be like Lin Xuan, it is not an exaggeration to be cold-blooded and ruthless.

That feeling was like a chess piece being discarded and gone, and Qin Lang really couldn't agree with it in his heart.

Lin Xuan didn't mean to blame Qin Lang, he looked at the rotating figures in front of him, and was silent for a long time before he spoke.

"When I was so young like you, I didn't understand, and I was even very angry, but looking at these ancestors, how many of them are dying, I can live so long, I am content."

"Geosurgery is like what the outside world says, like chicken ribs, tasteless food, it is a pity to abandon it, once the research is successful, the future of mankind is self-evident, I forgot to say, Xiang Ye and Liu Qingge are my sixth batch of masters, you are so smart, think about why?"

Qin Lang was stunned for a moment, then looked at the dense small characters under the portrait, looked at it for a long time, his eyes fell back on Lin Xuan, he was silent, and finally sighed helplessly and said softly.

"Because, they are not only your high feet, but also your bodyguards, Lin Lao should be the seventh son of metaphysics in the previous generations, and the ultimate goal of the remaining six sons is to be the inheritor of the surgery of the protected area, I think in order to protect you, your contemporaneous life should all be dead."

Although he didn't want to admit it, Qin Lang still told this cruel guess that he didn't want to admit it.

This is indeed difficult for Qin Lang to accept, but he has to accept how important the importance of the inheritor of geosurgery is.

"So, Qin Lang, that's why I brought you here, you are smart, calm, solid in theoretical research, have a sense of the overall situation, and have excellent leadership and judgment, you are definitely qualified to be one of the inheritors."

"Now that I have the heart of the white dust, plus you, this is the only one in the Xuan Academy in the past hundred years that has a dual inheritor, and the chances of human survival in the future are greater."

"After living for so many years and experiencing too many things, my heart has long been numb, I am destined to be a person who is going to hell, it doesn't matter if I die or not."

"Qin Lang, I don't want to force you, since you know this cruel truth, but you still have a chance to regret it, no matter what choice you make, I respect you."

After speaking, Lin Xuan didn't speak, his eyes were slightly closed, giving Qin Lang enough time to think.

Even if Qin Lang withdraws, it will not affect his choice of other disciplines, if Qin Lang decides to accept it, it means that his future fate is completely tied to the future survival of mankind.

What will happen later, how many people will die for him, it is unknown, the reality is cruel, once it is linked to the survival of the human race, everything will be cold-blooded and cruel.

Qin Lang's silence didn't last long, only half an hour, and he asked directly.

"If I become one of the inheritors of geosurgery, I have better theoretical research, and whether others can change it for me."

Lin Xuan's slightly closed eyes opened, he looked at Qin Lang, a little surprised, but he quickly understood what Qin Lang was thinking, and said softly.

"Theoretically feasible, but even if you are smart, compared with the empirical theory accumulated by your ancestors for more than a hundred years, I am not optimistic about you, maybe your new theoretical research direction will make the people close to you die earlier, after all, there is not much time left for us."

"Well, I understand Lin Lao's good intentions, after all, it is a matter of life and death, but I still want to try!"

"So, that's your answer?"

Qin Lang snorted lightly, and a smile appeared in Lin Lao's eyes, his task was completed.

Qin Lang's final major department is still geosurgery, if nothing else, Qin Lang will never be able to watch Luo Yingying and Zhou Shaohua die in front of him because of protecting Bai Chen's heart.

Even if it is the worst plan, he will die before Luo Yingying and Zhou Shaohua.

And this is only the worst plan, besides, he still has a chance, even if this chance is very slim, he has to try his best, if he stands still, nothing can be changed.

This time, not for himself, but for Luo Yingying and Zhou Shaohua.
