The most fatal artery was stopped, but the bleeding from the wound did not stop.

Zheng Rui didn't know what the proportion of blood loss this young lady had reached, but looking at her pale face, it should be quite serious. Now there is no rescue, and there is no plasma replenishment in the short term, and it is estimated that it will be too late to wait until the wound clotted on its own to stop bleeding.

In desperation, she suddenly had a conjecture: she is an immortal type with super recovery ability, so if she puts her tissue on someone else's wound, if she can also grow together, won't she be able to stop the bleeding?

Other tissues have MHC tissue rejection, but blood should be able to try. Zheng Rui is blood type O, commonly known as a universal blood donor, there is no blood group antigen on the red blood cells, a small amount of blood transfusion does not matter much, and the blood infiltration wound should be fine.

"Don't sleep." Zheng Rui patted the young lady's face, "What blood type do you have?" ”

“A…… B......" The young lady spat out this answer from her pale lips.

Type AB, universal blood recipient, there are no blood group antibodies in the plasma, just right, great.

Zheng Rui did not hesitate to use the monster's claw to stab his left wrist. It was indeed painful, but the arterial blood flowed out before the wound healed and dripped into the wound on the young lady's thigh.

I don't know if it's Zheng Rui's delusion, she actually felt that the bleeding from the wound gradually stopped.

The wound on Zheng Rui's wrist healed quickly, and then she waited for a while, and was surprised to find that the bloody wound on the young lady's leg really no longer oozes blood.

So she was right in her guess - it was really ...... It's amazing.

However, the wound is now contaminated, and it has been gnawed by the monster who doesn't know what it is, and it must be cleaned to prevent infection. It is not possible to use tap water, and the current tap water pipes are no longer airtight. Zheng Rui hurriedly ran back to the commissary and came back with two bottles of pure water.

When she saw the young lady again, she was surprised to find that her lips had regained some blood. The pure water washed away the blood from the wound on the leg, and the wound had even begun to heal.

How good is her blood?

That's too strong, isn't it?

At this time, although the young lady was still lying on the ground weakly, she was no longer so moribund when she spoke. She said to Zheng Rui: "You go quickly......"

"What?" Zheng Rui was a little strange. I saved her life, so why let me go?

"Your blood ......," the young lady said weakly, "don't let anyone else see ......"

Why? Zheng Rui realized in hindsight that now that the rescue has not come, in the absence of medical treatment, it is estimated that he will be "requisitioned" to supply trauma medicine. However, in an emergency, it is understandable to draw blood to save people, after all, even in a safe period, the university organizes everyone to donate blood for free. Now only her blood is useful, but it is nothing more than to draw more blood, and her recovery ability is so strong, she can still continue to pass.

But now what she wants to know more is, is there only the little sister left in this community? With such a weak monster, Zheng Rui felt that it was impossible for any man to let the young lady almost be eaten by a monster.

"Are you the only one here?" Zheng Rui asked.

"No......" The young lady seemed to be a little anxious, and tears flowed from her already red eyes again, "You can go quickly...... They're going to be out in a minute......"

Who are they? Man, or monster?

Zheng Rui realizes that some things may not be as simple as she imagined, but the young lady reminds her to leave quickly, and she can't leave her in this potentially dangerous place.

I'm going to have to take her with me. Zheng Rui wanted to try to see if she could carry the young lady on her back, but when she pulled her up, she felt that she didn't seem to be as heavy as she imagined. Zheng Rui wanted to carry the young lady on her back easily, and then quickly ran back to her basement.

She put the young lady on the floor of the commissary, and explained a little embarrassedly: "I'm quite messy here, don't mind." Then he asked, "What do you mean?" What else is coming? ”

The young lady straightened up weakly, leaned her back against the shelves of the commissary, and in just a few moments her legs were able to move a little.

She took a deep breath and said to Zheng Rui, "Thank you." ”

"It's not a big deal." Zheng Rui sat down and said, "I have a strong recovery ability. Then she asked, "Do you know what that monster is?" ”

"They call it 'aliens.'" The young lady said, "I don't know what this is...... Could it be a mutant bug? ”

"It looks most like an insecta, but the number and structure of the large appendages don't match. And although they have a body structure like arthropods, they have eyes similar to chordates—they are not a species on Earth. Zheng Rui explained.

"How do you ...... Know? The young lady looked at her with some surprise.

"Oh, I'm from the biology department." Zheng Rui smiled a little embarrassedly.

The five scum of the student figure can also be a little useful when the mouth cannon.

But that's not the point, Zheng Rui asked, "By the way, how did you get caught by that 'alien', and did everyone else in your community leave?" ”

This question made the young lady silent, she wiped a handful of tears, and looked at Zheng Rui again. Although her face was still stained with blood and alien blue-green body fluids, it could still be seen that this young lady was quite delicate, and her fair complexion seemed to be a person who paid more attention to dressing up before, and should be at least a student or a white-collar worker.

It seemed that it didn't matter if she told Zheng Rui everything about herself, so the young lady looked away and said softly, "Five days ago...... That's when it happened suddenly, my boyfriend and I were living in Unit 1 of Building 3, and then suddenly ...... You know, then I found a basement with my boyfriend. At that time, there was a young security guard Xiao Li in our community in the basement, and later two boys from Unit 2 came to our basement, because Unit 2 did not have a basement. ”

Zheng Rui nodded, indicating that she was listening.

The young lady wiped her tears again and continued: "Because we don't know what happened, we lived together in the basement, but there were only a few packets of instant noodles and other things in the basement, and half of them were divided by the other people in the basement. A few people living in the basement discussed it and asked Xiao Li to go out for help. Afterward...... Xiao Li came back and said that the houses in the commercial area over there were gone, and there were still people robbing things from the underground supermarket in the shopping mall. He's brought us some back, and we're going to hide here now. ”

Zheng Rui felt that this was getting more and more runaway, but she still asked the information she wanted to know the most: "You should have a mobile phone, can't you go online?" ”

The young lady shook her head: "The mobile phone has no signal, and even the location information can't be used...... Now it's out of power. ”

Can't use location information? Doesn't that mean...... Even the navigation satellites are gone?

Damn, that's a bit serious.

But also, when aliens descend on Earth, they must get rid of everything floating in low-Earth orbit.

So it's aliens by default......
