A week later.

She was thin, weak, and weak. Even if she was just sitting in front of the test bench to read a book, Green's pale face couldn't help but sweat appeared on her pale face, with abnormal blood in her eyes, and she looked weak in breathing.

Per’anos turned a blind eye to this and said lightly: “It seems that oral administration does work faster than respiratory infections. When I was infected with lymph under the guidance of my mentor, I only had the symptoms of this in three weeks.” As he said that, Per’anos shook the green potion in his hand, and watched the potion produce a trace of life and handed it to Green.

Green took the medicine and swallowed it in one mouthful. Then he felt a life energy begin to moisten the whole body, and the feeling of weakness in his body was relieved to a certain extent.

After taking out the crystal ball, Green smiled bitterly after a little detection. Has the physical strength value dropped to 2?

Per'anos shook his head and put the hollow test tube in his hand. While using his mental power to explore the text information in his crystal ball, he said indifferently: "If the organisms in nature are infected with lymph and there is no treatment, it is absolutely necessary for those organisms to have a few months of weakness. However, in the wizard's laboratory, you just need to wait quietly. No one will threaten your life, just think of a serious illness."

"Um."

After answering casually, Green slowly closed the book, and fell asleep on the bed in the corner of the laboratory. Per'Anos looked at Green, as if he was recalling himself back then. After a sigh of emotion, he quietly left the laboratory.

…………

Two months later.

Green, who was almost dying on the bed, was so thin that he was skinny and blind, his eyes were blurred and unconscious. He wanted to sit up and continue the experiment before rest, but he had no strength.

Per'anos frowned and said, "Is it the high-speed breeding period in two months? Is it because of oral lymph? In this case, it will be one month faster than expected." After saying that, Per'anos's thin fingers opened Green's eyes. After a simple light-based witchcraft, he confirmed that Green's pupils had slow reactions.

"Due to the short time, is the energy absorbed by the body unable to keep up with the energy demand for large-scale reproduction of lymph?" After walking around the room for a few laps, Per'anos suddenly whispered outside the room: "Gahei."

The black cat ran over agilely, raised a black tail and said in confusion: "Old man, what's wrong?"

"Leave a little bit of your scent on him." Per'anos pointed to Greene, who looked dying on the bed.

"Leave some smell?" The black cat looked at Green's decay and whispered: "It's true that I have to do this so randomly, and I'll take it orally. Now I have to rely on me to save you." As he said this, the black cat jumped on Green's body, and after a moment, he raised his hind leg and a small water column fell on Green's face.

After urinating, the black cat jumped off the ground and said, "It's done."

"Yeah." After Per'anos agreed, he picked up the gem pearl from the laboratory bench and stuffed it into Green's mouth. This gem pearl was a prop that Green had obtained from the fat man. If it was held in his mouth, it could breathe underwater. However, Green had never had the chance to use it, but now it was used by Per'anos.

Per'anos slapped Green lightly, and with a wave of magic, Green's body floated up like no gravity, as if it had some repulsion with the earth.

Later, with a thud, Green was thrown into the large water tank where the plane fish was raised by the old wizard.

Perhaps because of the black cat's slutty urination, the fierce-looking plane fish actually fled away desperately when they entered the water in Green and swam to the other side of the fish tank.

…………

Three days later.

When Green opened her eyes, she saw herself lying in the water and immediately struggled instinctively. However, her excessively weak body made Green's so-called struggle look so powerless.

Dong, Dong, Dong.

Green heard the sound, and after calming down, he turned his head and looked over. He happened to see the black cat knocking on the fish tank outside the fish tank. The black cat said word by word: "If you have another day of cultivation, your master and your master's wife will prepare you for restorative food." The voice was a little blurred through the water, but Green could barely understand it, blinking twice to indicate that he knew.

At this time, Green was lying in the water in the bathtub, curious about how he could breathe under the water, and was surprised to see the plane fish that he didn't dare to approach on the other side of the fish tank; on the other hand, he began to sense the condition of his body. The fish tank and the water inside seemed to have some strange functions, which could actually produce a rare energy that nourishes the body. At this time, although Green's body was still weak, the lymph in his body seemed to have reached the limit that Green's body could bear, and it was no longer reproductive, and formed a symbiosis with Green.

A little tired, Green closed his eyes again.

…………

Two months later, after the crystal ball monitoring, Green's body had completely recovered and his physical condition reached 6 points. It should have been 7 points, but 1 point of physical condition was permanently lost due to excessive consumption of cell energy in a short period of time.

It is worth mentioning that the first thing Green did after he was able to act independently was to prepare a bottle of deodorizer to eliminate the odor left by Gai (Black Cat) on himself, and once again maintain a completely odorless physique. (Open the low-key halo.)

Per'anos nodded aside and said, "Recovery is good. In this way, you can practice the formal practice of mud-toxic body refining. Well, because your physique is low, you can only use some non-fatal irritating poisons. In this case, if you are a general wizard apprentice who practice mud-toxic body refining, you will definitely take or inject some weak poisons under the guidance of your instructor. But if you have a better choice, if you are here, you have a better choice."

As he said this, Per'Anos actually took Green to a room completely enclosed by magical ban, and then took out a fully enclosed metal vessel from it.

"This is a precious radiating stone with weak radiation intensity. However, although it is weak and equal, if exposed to the civilian world, people close to fifty meters will weaken and die within one day, and poisoning will appear to be different degrees within a thousand meters, which is a hazardous item that needs strict monitoring." As he said this, Per'anos said to Green: "However, this poison is most suitable for your early auxiliary practice. First, it will not be irreversible and lethal, and secondly, it can be reused. You only need to control the time of poisoning during the period."

After a moment of surprise, Green took the closed vessel and asked, "So how much physical fitness can I increase after every practice using the radiation stone?"

"About one." Per'anos affirmed: "Every time you practice, your body will recover for one month, so you can use this radiation stone to cultivate your physical condition to above 15 years. After a year, because your physical condition is enhanced, the lymphatic barrier has been passively poisoned due to the long-term passive toxicity of the radiation stone, and it will develop resistance to passive evolution. In this way, it will be difficult to rely on the radiation stone to practice again. At that time, I will guide you to regulate the real poison."

Passive evolution?

Green noticed a keyword used by mentor Per'anos.

Because of its super adaptability, lymph has extremely strong passive evolution. It is precisely because of this characteristic of lymph that the wizard used his wisdom to develop mixed poison body refining witchcraft, allowing the lymph to form a thick layer of "armor" on all cells of his body to enhance the "physical constitution" of the cells.

As for the human body itself, although it also has the ability to passive evolution, because almost all living organisms have such capabilities. However, the adaptability and evolutionary speed of the passive evolution ability of human cells are far behind the lymphatic structures, and the two sides cannot even be compared. Therefore, the wizards have never cared about the passive evolution of the body cells themselves.

but……

Green is different.

Because of the accompanying worm fly snails, Green's passive evolution in his body far exceeds that of normal humans. In this way, wouldn't his own cells "evolve both internal and external cultivation and dual evolution"?

In other words, if Green practices the mixed poison body refining once a month, the effect should be twice that of normal practice!

Of course, these are just Green's inferences at this time and have not been actually verified.

Per’anos took Green to an empty and closed room and said, “The radial stone must be used in such a restricted room, otherwise it will be transmitted to the surrounding space through some bands. The old guy downstairs is okay, if the guy above is also there, and he is in a bad mood, it will be annoying again.”

Green nodded, indicating that he remembered it.

"Yes." After Per'anos opened all the room restrictions, he carefully opened the lid of the metal vessel. Suddenly, a black stone that looked ordinary appeared in Green's field of vision. At the same time, his body was accompanied by an indescribable sense of repulsion, as if the instinctive sense of crisis appeared in the cells of the whole body.

"For the first time, half a minute is enough." As he said this, Per'anos closed the metal lid in half a minute and then carefully kept it in the secret room.

Green was a little confused, and at the same time, his body looked a little weak, and asked, "Teacher, at this stage, how long will my weakness last after every practice?"

Per’anos thought for a while and said, “Now you are exposed to weak toxicity, and weakness will last for one day. During this period, the lymph in your body will greatly absorb the energy of your body due to passive evolution, so your physical constitution is only about half of the usual ones. Therefore, when you are exploring and traveling in the wild, do not practice mixed poison body refining. And after about ten days, your physical constitution will grow, because the lymphatic barrier on the cell strengthens. The next twenty days are the self-regulation rest time for lymph, and prepare the corresponding energy for the next passive evolution.”

…………

Ten days later, Green held a crystal ball in his hand and murmured with surprise on his face: "8 points of physical fitness has really increased by 2 points! Sure enough, after the cooperation of the snail and lymph, with the dual passive evolution, has the body cells achieved the dual cultivation characteristics of both internal and external cultivation?"

Excited, Green began to think about the benefits he would gain.

The first is to practice twice the speed, so there is no need to mention this benefit. The second advantage is that after being invaded by weak poisons, Green will have higher physical resistance than ordinary wizard apprentices, which means that Green's body has a greater room for tolerance. The advantage brought by this is that Green does not have to accurately determine the toxicity of each time to the limit required by Per'Anos.
