When Sun Wuru sat on the flying machine and looked at the familiar castle, a group of flying birds were alarmed and flew out of the forest.

In the air, the smell of spring came to the air. The vegetation is lush and verdant.

If it weren't for the low graves erected at the edge of the forest, as well as the figure kneeling in front of the tombstone, Sun Wuru really felt that he was dreaming.

Only in dreams is there so peace and tranquility.

No killings, no tombstones, no mourners.

He hesitated, but walked to the cemetery.

He knew there was a cemetery in the academy, but it was buried by people he didn't know. Yan Qi also returned here, of course, and since then, Manzhu has been a regular visitor there.

But now, there's one more friend here.

In this way, there is more concern.

Tombstones are ordinary, but because they have a name, they have meaning.

"Qi Huan"

A gray-haired man knelt beside the tombstone, put a bouquet of flowers, and gently rubbed the tombstone with his rough hands.

Qi Xiang is not old, but compared to when Sun Wuru rescued him from the nursing home, he is a little older.

Nowadays, it is really the white-haired people who send the black-haired people.

The Federation finally woke up Qi Xiang, and by the way, he was cured of his long-standing illness, and his body now has no problems and is very healthy.

But Qi Huan couldn't see it.

He didn't like his father, because he didn't care about Chen Si'an, and because he never cheered up and had the appearance of a father.

But Sun Wuru knew how much he wished he would wake up when he talked about Qi Xiang in the recuperation room.

Guan even brought Qi Xiang back in the last few days of that incident, although this was also one of the "nameless" schemes, but he also did his best.

It's a pity that Qi Xiang couldn't take one last look at his son.

Life is not seen, and it is like a participant.

As if sensing someone behind him, Qi Xiang turned his head, he hadn't seen Sun Wuru, he was stunned for a moment, and then stood up tremblingly.

When he opened his eyes, he didn't know what was happening. I didn't know that he was kidnapped by "nameless", and I didn't know that his former friend Ming Qingchen was the "nameless" cadre Cheng Qingsheng.

Of course, he had heard the name of the Academy of Tius.

As the only secret institution of higher learning in the Federation, Qi Xiang had only heard the name. So when he walked out of the castle, he thought he had traveled back to ancient times.

But the news of Qi Huan's death still brought him back to reality.

How familiar this feeling is.

It's exactly the same as when Si'an left.

Now, there is indeed no one left around him.

He didn't bother to know the cause of Qi Huan's death, and he still didn't know the existence of "Nameless". I just came here on time every day to sweep the grave, and the rest of the time, I was in a daze in the room.

"His lifespan will be reduced, and his psychological pressure will be too great." In Sun's ruthless mind, the cold voice of "Kars" came.

He had become accustomed to hearing the sound of the machine in the capital, as long as he called it by the right name.

"Isn't there anything you can do?" Sun asked ruthlessly.

"If we are in more than five dimensions, we can go back in time. But in this world, sorry, not all diseases can be cured. ”

"Time machine, why can't you build it?"

"Kars" didn't bother to pay attention to him at all, and directly responded with silence.

"Zieber." Sun ruthlessly stepped forward to support Qi Xiang. Although Qi Xiang was a little scared, he glanced at Sun Wuru and still stood in place honestly.

Everything here, he was so strange. Everything that the academy prepared for him, he rarely used, even the food, he ate very little.

It looks weak.

"I'm a friend of Qi Huan......" Sun Wuru didn't know what to say, and stopped talking.

"Okay, okay." Qi Xiang patted Sun's ruthless palm, and glanced at the tombstone at his feet again, as if he was planning to return to the castle.

Looking at the misty look in his eyes, Sun Wuru felt that there was already a deep generation gap between the two of them, Qi Xiang was already old, and what he was holding on to might just be an empty shell without a soul.

This man, once beautiful and timid, now has nothing left. In his past, no one cared about this evaluation for a long time.

"It's windy outside, let's go back." Sun's ruthless tone was rarely soft.

Qi responded with a sigh, turned and slowly left the purpose, and carefully walked the path to the castle, lest he step on the lawn next to it.

Sun ruthlessly followed behind him, if he still wanted to help Qi Huan do something, maybe he took care of the old man in front of him.

Life is too easy to pass away. Sun ruthlessly sighed in his heart.

Suddenly, he seemed to sense something, and raised his head, and An Ran was standing not far away.

Before they knew it, they had reached the tower in the center of the castle.

Since that incident, the academy has assigned him an external mission, and he has not had a chance to go there.

After a few weeks of not seeing her, Senior Sister An Ran's face looked a little haggard, and he didn't know if she was also involved in that battle, but until now, he still believed in her.

After all, her eyes are always so clear and transparent.

But he could never guess what she was thinking.

"Ruthless, bring Uncle Qi Xiang up and sit." An Ran seemed to be waiting for them, she looked at Sun Wuru, then at Qi Xiang, and then smiled.

Qi Xiang had a puzzled look in his eyes, and An Ran didn't have any more explanations, turned sideways, and invited Qi Xiang to climb the tower.

The tallest tower in the heart of the castle is connected to a large underground space downwards and upwards is the rector's office.

When Sun Wuru walked up to the top floor again, he found that the top floor was not as bright as before.

An expensive chair was placed by the window. There used to be a dark mark on the bluestone slab, but now, it is perfectly covered by this chair.

The chairs were originally placed here, even the people sitting on them.

Sun Wuru met the principal for the first time in the principal's office.

Lin Wei is still wearing a fiery red coat and crimson gloves today, and his broken right arm has been re-grafted through biological cultivation, but he still needs to cultivate.

But when Sun Wuru saw this red, a figure flashed in his mind.

In his dream, one of the four people in that small room was wearing this flaming red coat. He saw the side of his face at the time, which was very similar to him.

He is the principal.

This was the first time he had seen the principal, not the rotten old man at the opening ceremony, but a middle-aged man with a wicked smile on his face and some crow's feet at the corners of his eyes.

He remembered that Qin Chu'an had mentioned that there were so-called "four kings and three emperors" in the Federation, and one of them, he suspected was the principal of Tius Academy. In any case, this mysterious location has always been an object of fantasy for all.

But in Sun Wuru's eyes, this man is a little too peaceful and too ordinary.

At only sixty years old, Lin Wei lived younger than most.

He crossed his fingers and sat on the red inner village, with a chair studded with gold and diamonds on the armrest, and looked at the two men with a smile.

Sun ruthlessly found that he was looking at the same face.

He was sitting, standing in unison, but the looming momentum was pressing down on the old man who had just experienced the pain of losing his son.

"This room is specially made, and anything said here will not be recorded in any of the Federation's databases." Lin Wei said endlessly: "This is a little privilege for me, as the principal of this academy. ”

Hearing this, Qi Xiang was indifferent, even though he knew that Lin Wei was talking to him.

"I'm really sorry about your son." Lin Wei put away his frivolous expression, solemnly walked in front of Qi Xiang, and bowed ninety degrees: "I tried my best to find out who was behind the scenes, but in the end it was a step too late." The person who prompted your son's suicide came from a terrorist organization, and your former colleague, alias 'Ming Qingchen', was the most important member of the organization. He's in Piris Prison right now, and I'll arrange for you to meet if I get the chance. ”

After saying this, Lin Wei maintained a bowing posture and did not say another word.

Sun Wurui, who was standing on the side, faced this sudden unfolding and silently stood beside An Ran. He tried to swap "Kars" and found that there was no response.

Here is really as Lin Wei said, all the information will not be leaked to the outside world.

And when Qi Xiang heard his words, the expression on his face was finally a little moved.

He knew that this academy had a lot of secrets, but he didn't expect it to be so magical.

He didn't believe it was a coincidence.

So he told a secret that had been buried in his heart.

"There's a loophole in 'Friends.'" Qi Xiang's voice was soft, but firm.

As soon as this sentence came out, even An Ran covered his mouth. And Sun Wuru was even more stunned.

Lin Wei raised his head, took Qi Xiang's hand, and asked him to sit in his place, serving a cup of hot tea with a respectful attitude.

"Tell me more."

Sun Wuru noticed that his hands were trembling slightly, and it seemed that even he could hardly imagine hearing such a secret.

"At the time, no one thought it was a loophole, including me, and it was a brilliant idea. Such a design allows the 'friend' to choose the transmission mode of the signal independently, so as to ensure that the information conveyed by it can be received in various environments. Neither the subterranean seabed, nor the distant Antarctic Pole, nor even the Moon or the Sun affect the transmission of signals. Although Qi Xiang has spent nearly 20 years in the wilderness, he still exudes a sense of confidence when he talks about this matter.

"But if this is a loophole, someone should have done a polygraph for you when you left the capital." Lin Wei re-investigated the events of that year.

"Yes. So this vulnerability, I just discovered. Qi Xiang said: "When I learned the cause of my son's death, I realized where this quantum information transmission model based on the human brain is most likely to be used." I've always overlooked that sometimes the reason for the development of technology is not for the sake of the stars and the sea, but also for the better conquest of other people. Speaking of this, Qi Xiang couldn't help but shake his head.

And Sun was ruthless, and he felt a chill down his spine when he heard it.

According to him, Sun's ruthless gift may have been planned twenty years ago, when the "friend" was established.

"It's not enough to know this, you asked me to come, I should also want to know who said this idea back then." Qi Xiang looked up at Lin Wei, barely pulling out a smile.

"Coincidentally, today is the first time I've seen this child." He suddenly turned to Sun Wuru and sighed: "The person who proposed this idea to me back then, I don't know his identity or his name, but he looks very similar to this child. ”
