"Blackie." Back in Blackie's underground storage room, Lu Yin called in a low voice.

Suddenly, a black shadow rushed out of the dark passage, and then threw himself into Lu Yin's arms.

"Xiao Hei, don't make trouble, I'll ask you something." Lu Yin put Xiao Hei on the ground, "If yes, you just nod, no, you just shake your head, understand?" ”

Then, Blackie nodded.

"Six years ago, after I threw you out, was it the guy who was traveling with us who ran away with you with you?"

Blackie nodded.

"It was because he fell into the river that you were separated, didn't you?"

Blackie still nodded.

"It seems that Xiao Yi really didn't lie to me." After getting Xiao Hei's affirmative answer, Lu Yin really trusted Xiao Yi, but the darkness of the gladiatorial arena made Lu Yin still choose to leave a way back for himself.

"Ready, we're going to have a big operation next." Lu Yin touched Xiao Hei's head.

Then, Lu Yin picked out a few cans of canned food and put them in his backpack, found a large cabinet, and blocked the entrance to the storeroom, Lu Yin planned to use this place as a secret granary, after all, Xiao Hei has not been found here for five or six years, and it is still okay to see the safety.

After taking protective measures, Lu Yin returned with Xiao Hei and went to meet Xiao Yi.

Half an hour later, Lu Yin took Xiao Hei to a hospital.

"Blackie, follow me." Lu Yin took out his dagger, slowly pushed open the door of the hospital, looked at the zombies in the hospital hall that had completely decayed, and motioned for Xiao Hei to follow.

Lu Yin found the laboratory department on the hospital's guide board, and secretly prayed in his heart, "I hope there is still a blood container." ”

Lu Yin took Xiao Hei to hide from the zombies that had not yet been cleaned, hiding all the way, trying not to make any sound.

"Blackie, do you see this glass bottle?" Lu Yin showed Xiao Hei the small glass bottle in his hand, this is the glass bottle used to isolate blood samples, "You can go find such a big plastic bottle, or a glass bottle, and bring it to me, you know?" ”

Blackie sniffed at the bottle, then nodded and left.

Seeing Xiao Hei's movements, Lu Yin couldn't help but smile dumbly, "I asked you to see the size of a bottle, what do you smell?" The taste is different on every bottle. ”

But it's like Xiao Hei's instinct, and he habitually smells something before looking for it.

Lu Yin kept rummaging in the laboratory department, and after ten minutes, Lu Yin only found three small plastic bottles, but there were many particularly large bottles.

Just as Lu Yin continued to rummage, Xiao Hei came back upside down, and the little paws rubbed against the floor to make a faint sound.

Lu Yin looked back and saw that the backpack around Xiao Hei's neck was slowly filled with a pack of bottles.

"It seems that I really can't compare with you when it comes to finding things?" Lu Yin smiled bitterly, then took the backpack off Xiao Hei's neck and carefully counted the number of bottles.

In the end, Lu Yin selected ten plastic bottles with good seals and ten glass bottles from the bottles found by Xiao Hei.

Lu Yin uncorked all twenty bottles, then lined them up one by one, pulled out the dagger, and cut deeply at the wrist, and suddenly, dark red blood flowed along the wrist to the ground, this scene frightened Xiao Hei.

Xiao Hei just wanted to scream, but Lu Yin immediately stopped Xiao Hei with his eyes.

Lu Yin dripped the blood into the twenty bottles in turn, and then quickly plugged all the bottles, the strange thing was that the blood that Lu Yin had previously dripped on the ground had vaporized in the blink of an eye, and the blood in the bottles was still liquid.

In the few seconds that Lu Yin stuffed the bottle, the wound on his wrist had completely healed, leaving not even a trace of scar.

"Xiao Hei, listen to me." Lu Yin found two suitably sized boxes and placed the bottles full of blood in turn, "When you are injured, take out a vial of blood and sprinkle it on the wound, but remember, you must let my blood enter your wound within ten seconds, otherwise even if the blood is not vaporized, it will become ordinary blood." Remember? ”

Xiao Hei saw that Lu Yin was so serious, so he knew the importance of this matter, and then nodded to indicate that he knew.

"Also, don't let anyone know about this, or we'll both die." When Lu Yin said this, he suddenly slapped his forehead, "You can't speak, you can't tell others if you want to, and you can't do it with the same kind, you know?" ”

Xiao Hei was amused by Lu Yin's words, and his tail wagged back and forth.

"I'll wait for you here, you send these ten glass bottles back to the underground storage room, and then come back to me." Lu Yin hung the box containing the glass bottle around Xiao Hei's neck, and then instructed Xiao Hei, "Go and come back quickly, and cover the entrance when you leave." ”

After Xiao Hei heard Lu Yin's words, he turned around and left quickly, leaving the hospital in a few leaps, while Lu Yin sat down on the ground, looking at his already healed wrist in a daze.

"In the lab for five years, professors and high-end people didn't understand where I had mutated. How could I have studied it myself, and I don't know where the limits of my self-healing ability are. ”

"All in all, it's better to get as little damage as possible, in case this ability is gone, you will really die."

In the five years of the laboratory, the professor exhausted all kinds of methods to experiment, and finally did not figure out where Lu Yin mutated, at the beginning of the discovery that Lu Yin had a self-healing ability, the professor suspected that Lu Yin's blood was mutated, so he extracted Lu Yin's blood to start the experiment, but only found that Lu Yin's blood was sealed and preserved in vitro, within ten seconds of contact with the air, basically can heal most of the non-fatal injuries.

And once the blood is out of the body for more than ten seconds, it will vaporize, so the professor drained the blood in Lu Yin's body, and Lu Yin still healed himself within two days, so the professor shifted his attention to Lu Yin's bone marrow, after all, blood is made of bone marrow, but in the end, nothing was found, even if Lu Yin's entire spine was peeled off, the result was still that the blood bone marrow would vaporize once it was out of contact with the air for more than ten seconds, and if the air was isolated, after ten seconds, it would become ordinary organ tissue.

For the next four years, Lu Yin was taught to conduct dissection experiments from hair to toenails, but there was still no substantial progress, and Lu Yin spent four years in this kind of daily cutting by the blade.

Just when Lu Yin recalled the past, Xiao Hei returned to the hospital again.

Lu Yin looked at the time on his watch, ten minutes, "Xiao Hei, what speed are you?" It took us half an hour to walk here, and you went it all by yourself, going back and forth every ten minutes? ”

"That's all for the newly awakened speed powerhouses, isn't it?"

Xiao Hei heard the exclamation in Lu Yin's tone, and happily spun in a circle, wagging his tail non-stop.

Seeing Xiao Hei's performance, Lu Yin suddenly had a feeling of going back to the past, but Xiao Hei was only the size of his palm at that time, and he happily kept spinning in circles as soon as he fed it meat.

Lu Yin took out the box containing the plastic bottle from his arms, then wrapped it tightly with gauze, put it into a cloth bag, and hung it around Xiao Hei's neck, "Be careful, this is your life-saving artifact!" ”

After speaking, Lu Yin took Xiao Hei out of the hospital, and then went to the place agreed with Xiao Yi to meet.
