Man in the old days, Lord of the Seven Sins

Chapter 46 Help me catch some mice and come back
Human blood is usually composed of plasma and blood cells and is red in color.

And ghoul blood.

Rhodes took a half-syringe of a dark green liquid suspected of ghoul blood from the dead ghoul on the table, and injected it into a transparent glass test tube.

Set aside on a shelf.

Serum belongs to blood cells, and generally contains various plasma proteins, polypeptides, fats, carbohydrates, growth factors, hormones, antibodies, etc.

Here, in order to fight against the ghoul toxin, the antibody that Rhodes needs to obtain is in the serum.

The preparation of serum is generally done by centrifugation, but because of limited equipment.

Rhodes can only take the most basic extraction method and let it stand naturally.

The serum of human beings and animals is naturally left for a period of time after extraction. After the blood coagulates, the light yellow transparent liquid that is precipitated after the clot gradually shrinks is the serum.

As for what the ghoul's serum looks like.

Rhodes hasn't figured it out yet, the blood just drawn hasn't coagulated yet.

In order to do a good classification comparison.

Rhodes used a syringe to draw half a syringe of dark green blood from the bodies of the other 4 ghouls, and placed them in transparent glass test tubes on a shelf.

Label it No. 1 - No. 5.

In the end, Rhode walked up to the ghoul whose cheek had been crushed by himself, and drew blood.

The drawn blood is half red and half green in color.

Rhodes frowned.

He drew a full tube and labeled it number 6.

Rhodes waited.

After naturally standing for a period of time, a layer of light gray liquid suspected of serum was precipitated on the coagulated blood of test tube 1, and then test tubes 4 and 5 also appeared.

However, there seemed to be some kind of wriggling parasite in the blood of No. 2 and No. 3, which made the blood unable to coagulate.

As for the No. 6 test tube, the proportion of red blood is decreasing, and the proportion of green blood is increasing. Some dark green bugs that are relatively smaller than those in No. 2 and No. 3 test tubes are wandering in it.

Continued to wait for a while.

The light gray liquid precipitated from the upper layer of coagulated blood in test tubes 1, 4, and 5 has been completely separated from the coagulated blood. Rhodes used a syringe to extract the light gray liquid, injected them into three new test tubes, and relabeled them. The three numbers 3, 7, and 8 are placed on another shelf.

The parasites in test tubes 2 and 3 were still active, and the blood showed no sign of coagulation.

The blood in the No. 6 test tube has completely turned dark green, and at the same time, the small worms in it have grown to the size of the No. 2 and No. 3 test tubes.

The red blood in test tube No. 6 is suspected to be human blood, and human blood is dark green blood that was swallowed by these dark green bugs and turned into a ghoul.

Then a conclusion drawn from this.

These dark green bugs are likely to be the culprit that caused humans to turn into ghouls.

As for how to confirm it.

Rhodes put down the notebook that recorded the experimental analysis information.

He walked up to Old Hoffen.

At this time, Old Huofen had completely lost the angry appearance just now, and he was sickly, like an old man who was about to die.

Rhodes removed the stick stuck in Old Hoffen's mouth, and asked, "How do you feel now?"

"Oh, Old Hoffen feels like he's about to die. There seem to be countless green things in front of my eyes. It's a pity that they are not the banknotes I love, but squirming worms."

Confused words, the old Huofen seems to have lost his mind at this moment.

Rhodes narrowed his eyes.

"Aesop, help me catch some mice and come back."

"Follow your orders."

Rhodes threw the black leather gloves possessed by Aesop out of the window.

Aesop squirmed his tentacles, turned into a mousetrap and rushed into the forest.

It never thought that one day it would be forced to go to the forest to catch mice for a bite to eat.

But who let it follow a master who seems to be rich in research attributes?

Moreover, the core of the devil is still in the hands of the master, and Aesop can only obey his orders, doing things that he has never done before.

Old Hoffen's body was re-bound by Rhodes, his arm bitten by the ghoul was exposed.

Rhodes cut off the rotten cloth on Old Hoffin's arm, fully exposing his wound.

In the rotting sores, some dense dark green worms were clearly visible moving.

Pick several worms with tweezers and put them in a transparent container.

Rhodes used a new syringe to draw two tubes of blood from Old Hoffen's left and right arms.

Label them No. 10 and No. 11 respectively, and put them on separate shelves to stand.

The blood in test tube No. 10 was drawn from the arm bitten by the ghoul, nearly one-tenth of the blood had turned dark green, and the remaining nine-tenths were still red.

Test tube No. 11 is completely red.

罗德接着从7号试管中抽取少量血清，分别滴入2号、3号、6号以及10号试管进行对比实验。

Rhodes looked at the pocket watch, started timing, and recorded the data in the notebook.

15 minutes.

Test tubes No. 2, No. 3, and No. 6 did not move.

Test tube No. 10 is suspected to have weakened blood conversion speed.

30 minutes.

Test tubes No. 2 and No. 3 did not move.

A trace of red blood appeared in the No. 6 test tube, which was suspected of blood reversal.

The blood conversion of test tube No. 10 stopped completely, and there were signs of turning from green to red.

45 minutes.

Test tubes No. 2 and No. 3 did not move.

A quarter of the blood in the No. 6 test tube was red, and the blood was successfully reversed, and a small part of the dark green worms died.

Test tube No. 10 is all red.

60 minutes.

Test tubes No. 2 and No. 3 did not move.

Three-quarters of the blood in test tube 6 was red, and a large number of dark green worms died.

Test tube No. 10 is all red.

Experimental results:

1. The antibodies in the serum play a key role, the ghoul toxin is removed, and the blood is successfully converted.

2. After a period of time after human beings become ghouls, the serum cannot eliminate the ghoul toxin, and the blood cannot be converted.

3. The shorter the human being is infected with ghoul toxin during the ghoul transformation process, the faster the serum can eliminate the ghoul toxin.

4. The safety cannot be guaranteed at present, and it needs to be confirmed through further research.

Subsequent experimental assumptions can be made:
1. Serum safety experiment.

2. The hypothesis of the finalization time required for human beings to become ghouls.

Put down the notebook.

Rhodes looked towards the door.

A black tentacle pushed open the door.

The squirming Aesop entered the house.

Its tentacles are entwined with five gray, furry mice the size of a fist.

"Great master, Aesop is back."

Aesop lifted the five frightened and screaming mice to Rhodes as if claiming credit.

"Well, you're doing well."

"The dead No. 2 is yours now."

Rhodes pointed to the dead No. 2 ghoul. Due to the inability to separate out serum from its blood and the cause of death, it completely lost the effect of the experiment. It was only reasonable for Aesop to dispose of it as a slop bucket.

"Praise be to you, great master!"

Aesop couldn't wait to roll up the No. 2 ghoul with his tentacles, moved it to the mouthparts of his abdomen, and enjoyed it deliciously.

Rhodes checked the status of Old Hoffen, and it was still ok. He turned around and looked at Aesop's waving tentacles, and said in a low voice: "Now there is a task for you, if you handle it well , that number 3 is also yours."

"You say."

The green power of greed floated from Aesop's body and poured into Rhodes' body.

"Follow my instructions to do something."
