"Not from this world?" Su Ru was curious, "How could you guess that?"

"You can see if you look at these things. The white coat was very flattering, and took out a leather file bag from the pile of materials and handed it to her.

The file bag was obviously some years old, and it looked very old, and it was marked 'Subject 1', and it seemed that these people really regarded this unfortunate cultivator as important research material.

This file is not only thick, but also very heavy, Su Ru directly poured the contents on the table, and immediately there was a crackling sound.

"We haven't figured out what this thing is until now, but we don't think it exists in our world. The lab coat pushed the glasses on the bridge of his nose and found a swarthy wooden sign with strange symbols carved on it.

Su Ru took the wooden sign thoughtfully.

Although these white coats help to abuse, I have to admit that the brain melon seeds are still quite smart, not to mention that they don't know the otherworldly characters on it, just say that the wooden card itself has been studied by them I don't know how many times.

It's a pity that this wooden sign is light and fluttering, it looks quite fragile, but in fact it is indestructible, not even bullets can penetrate it, and there is not even a trace left, and ordinary humans have no way to take this thing.

Even Su Shijie was very interested in this thing at the beginning, but unfortunately, after studying it for so many years, he still didn't understand what kind of material this thing was.

However, these white coats are very interested in this thing, in addition to this wooden card, this person has some other strange things, such as a black rag bag, which looks nothing special, but it is as invulnerable as a wooden card, and it cannot be broken at all, otherwise this thing would not be regarded as a special item and all placed in this important document bag.

There is also a strange book, which is also invulnerable, and the words written on it have never been seen before, so naturally they can only put it aside.

But what these things are, they are not a big deal for Su Ru, who has accepted the inheritance of the other world.

The wooden plaque is a order representing identity, and the strange words on it represent the meaning of 'Tongtian', which seems to be a sect's identity token, and the black and shady broken bag is the Qiankun bag, but it has been damaged, and the things inside are naturally gone.

The things recorded in that book were very interesting, it looked like a diary, and it was estimated that it was also written by this cultivator, and she flipped through it at random and got a general idea.

This cultivator is really from another world, just like Lou Sichen, and even he is an innocent person who was implicated in the disaster of the Lou family's chaos.

But whether he is really innocent or not is not mentioned for the time being, this person is much luckier than those powerful monks, because at that time, Lou Xiangyi blew himself up, although he was also involved in the space-time rift, but because his race has two gods, so after he was shattered by one god, he relied on another weak god's soul to find a space-time node and escaped with his life.

However, his injuries were too severe, even if there were no cultivators in this world who were thirsty for killing, this piece of heaven and earth energy was not enough for him to repair his wounds.

Later, he was picked up by Su Shijie and others, and this diary was naturally not recorded again.

"That suggestion for blood exchange cultivation, did this person tell you?" Su Ru closed the diary, and his gaze fell on the cultivator who was soaked in the solution.

"It's not. The white coat shook his head honestly, it was thirty years ago that he saved this cultivator, and the plan for Su Ru's family started more than forty years ago, how could it be that this cultivator told them?" ”

"Then how did you know that there was such a thing as blood exchange cultivation?" Su Ru was really surprised.

She didn't think that someone like Su Shijie would be so crazy for one of his own conjectures, and she must have confirmed the authenticity of this matter somewhere before she did it.

After all, Su Jianwu, who had just been born, stood behind the aunt and grandmother of the Lin family who was not easy to mess with, and Su Shixiao, the famous general of the new country!

Even if he is Su Shixiao's younger brother and really touches something that should not be touched, Lin Yaxin will definitely not be merciful.

So she was really curious, from whose mouth did this Su Shijie hear about such an unreliable thing as blood exchange cultivation?

"I don't know about that. The coat shook his head, they were just in charge of research, and they didn't care about the rest.

Su Ru smiled coldly, but didn't say anything, just smashed the heavy glass jar with a punch, and the liquid soaked in this cultivator immediately splashed, and the cultivator naturally fell to the ground.

She listened to the sound of this cultivator's almost imperceptible breathing, and a trace of hesitation flashed in her eyes, although he only had one breath left, it was really easy to save him, after all, she was only one step away from becoming a saint-level talisman doctor now.

But what if, this person is the enemy of the Lou family?

Su Ru didn't want to save a white-eyed wolf, so after thinking about it, she decided to put this person into the small interface first, and by the way, she left a note outside the small bamboo house, explaining the origin of this cultivator, and when Lou Sichen came in, let's see if I want to save this guy.

"Alright, go about your business, you know what I want. Su Ru said to the white coat without a trace of emotion.

This person is also quite knowledgeable about current affairs, so he immediately nodded and went to the research room to continue to conduct experiments with Su Shijie's family of four.

Human experiments, naturally can't expect these people to be gentle, Su Ru didn't deliberately look at it, but he could also hear the screams of Su Shijie's family.

She was still standing on the side of the material room, and in her ears was the terrible screams of the family of four, but what she was thinking about was that her little brother had been arrested for so many years, and was he also used as a research material for all kinds of tosses like the cultivator just now?

As long as she thought about it, she couldn't control the anger in her heart.

Changing blood for cultivation, such an unreliable thing would actually become the ultimate goal of her family's ruin in her previous life, and she felt very sarcastic when she thought about it.

"By the way, I have to see who told Su Shijie about the blood exchange cultivation!" Su Ru patted his head, almost forgetting such an important event!
