Li Ru found a pair of medical gloves and a mask in the locker of the clinic, and put on the white coat hanging in the wardrobe by the way.

With the gloves, Li Ru began to try to give the monster a full body massage, of course, not really massaging it, but by stroking and pressing, to further understand its body.

Seeing is not necessarily believing, this is a sentence that Li Ru thought of touching the body of the monster, the monster looks very thin and shriveled, but it feels very powerful, it is like a skin and bones, but this skin is not a bone, but a strong muscle, the monster's body fat is very low, so it looks like it feels very weak, if you simply consider brute force, ordinary people are not necessarily opponents.

Gently stroking the monster's skin, through the gloves, Li Ru could feel its armor-like skin, the heat from his hands indicated that the monster's body temperature was very low, maybe they were similar to cold-blooded animals, when the temperature was too low, they would stop moving, which could also explain why they would rise at night, too low ambient temperature would greatly reduce their body functions, this inference is quite reasonable.

The monster has very little body hair, except for a little hair on the head, the hair in other places is basically gone, * it is also bare, and the reproductive organs are also obviously degenerated or disappeared, and it is difficult to distinguish the sex before death just by looking at the lower body.

Listening, and listening, Li Ru almost ignored an important thing that needed to be studied, he knew that their hearing was good, but how good it was, why it was good, was still a big question mark.

If you want to understand their hearing problems, you still have to start with their ears, I didn't pay attention to it before, the monster's ears are really big, at least twice as big as Li Ru, is this why they hear well, Li Ru thought so in his heart, but due to the lack of samples, maybe this is just that this person's ears were originally relatively large before his death, not mutated after infection, and it is too early to draw conclusions.

Li Ru really wanted to see if the internal structure of the monster's ears was different from that of humans, but it was unrealistic to think about it, so in the end, he still forgot it, at least not yet.

After tinkering for a long time, Li Ru has almost made all the parts that can be checked on the outside, as for the internal structure, he can only open the knife for verification, Li Ru no longer regards the monster as the same kind, and he can accept it psychologically, but he doesn't plan to do it yet, at least not today, he wants to be here tonight to see what the state of the monster at night is, if they will indeed be limited because of the arrival of the night, what is the specific limit, Li Ru feels that it is necessary to figure it out, if the monster is breathed after the knife, he can't continue, So I can't get my hands on it today.

It's still early, after checking that there is no problem with the monster's restraints, I went out to see Li Wei's situation, Li Ru threw away the gloves, after all, it's not very clean, God knows if it will carry any source of infection or something, direct contact may be risky, and there are spare gloves, so there is no need to be too economical.

"How did you get out? Done? Li Qiulan was slightly surprised when she saw that Li Ru had finally come out.

"Sort of, the first stage is almost finished, take a look at it in the evening, it's time for you to play tomorrow" Li Ru thought for a while.

"So fast? First of all, I'm not going to touch that. Li Qiulan still emphasized again with some unease.

"I know, I know, I won't let you touch it, you just need to watch from the sidelines, tell me how to operate, and if there is something abnormal, such as the internal structure of the monster is different from ordinary people or something, more something, less something, I really lack understanding of human internal organs, without you, I'm just a blind man lighting the lamp, it's useless." In order to reassure her heart, Li Ru also assured again.

"That's good, can I go back?" Hearing Li Ru's assurance, Li Qiulan was relieved, and then she was ready to take the first step.

Li Ru asked her to come over this time, just to let her be mentally prepared first, and naturally sent her back when she felt that it was almost over, and then turned back.

He wasn't going to go back yet, or there was something he could only do at night.

When Li Ru returned to the operating table, it was already dark outside, because there was no electric light, the room was very dim, Li Ru lit a few candles and placed them around the operating table, so that by candlelight, he continued to observe the performance of the monster.

At first, there was no result that Li Ru wanted, and the monster's reaction was no different from that of the day, until late at night.

"It's so cold!" Li Ru couldn't help but shiver, the temperature gradually dropped after nightfall, Li Ru forgot to bring thicker clothes, so he could only endure it silently.

The monster on the operating table somehow began to look different from the daytime, quieter, not writhing much, only the rise and fall of the chest and abdomen indicated that it was still alive, but the lack of writhing did not mean anything, maybe it was just because there was no external stimulus.

Li Ru tried to make some noise, and said a few words casually, but the monster didn't react as if he didn't hear it, which made Li Ru happy, maybe this meant that late night would be the best cover in the future.

In addition to being delighted, Li Ru walked into the monster's ear and tried to shout a few words loudly, in order to confirm his conjecture, but then the monster suddenly became excited, and began to struggle again, wanting to get rid of the restraints, which was like a basin of cold water poured on Li Ru.

Li Ru tried to adjust the position and the intensity of the sound to test the monster's perception at night, and finally analyzed from the results, the monster will indeed decline a lot in physical function at night, which is manifested in perception, that is, the sensitivity to surrounding movements is reduced, as long as it doesn't shout or something in its ear, basically there will be no reaction, that is to say, the temperature at night is low to a certain extent, the threat of the monster will be greatly reduced, Li Ru can't accurately measure the specific temperature value that makes the monster a waste, But knowing that they will basically lose their threat when the temperature drops to a certain point at night and enter a human-like state of deep sleep, that's enough for now.
