When the doctor saw the photo in Fang Liang's hand, he was immediately struck by lightning, and he panicked and wanted to escape.

He tried his best to resist the little boy, and the picture seemed to set up some horrible memories, and he couldn't speak normally.

The doctor's fierce reaction was something Fang Liang didn't expect, but after a change of thought, he was immediately relieved: the doctor must know something that caused him to lose his temper so much.

"Hey, take a hand! Keep him under control! Lu Ming jumped over at once, firmly clamping down on the panicked doctor.

"It's coming, it's going to be right away." Li Xiaoyu glanced at the medical notes and gave the prepared sedative medicine to the doctor, and the doctor who was struggling violently soon stopped trembling, like a puppet that had lost consciousness, and slowly regained his composure.

At this time, it is getting late, and once it is dark, the town of Copper Kettle will be completely surrounded by illusions, and it will be impossible to continue to go out to investigate.

The light can dispel illusions to a certain extent, but the dispersal range of the two flashlights is not enough to ensure the safety of life.

This stimulation was still too harsh, Fang Liang decided to wait for the doctor to calm down and return to normal emotions.

During the day, after communicating and discussing with doctors, Li Xiaoyu and Cao Zhengfei also sorted out a division of danger level areas.

Li Xiaoyu took out a hand-drawn map and explained to Fang Liang and Lu Ming the information he had obtained from the doctor: "The fields and grasslands near the doctor's home and the town were originally relatively safe places. ”

"The trees in the wheat field area can shade the sun, but they have not yet formed a large shade, and the same is true in the grass area."

"As long as you don't stay where you can't see your fingers, you won't be attacked during the day."

"However, the living conditions on this side of Copper Kettle Town are poorer, after the full-scale invasion of the forest, the dark ruins will be very dangerous, if there is no clear clue pointing to the depths of the darkness, it is best not to rush into the realm of no light."

Li Xiaoyu gave Fang Liang a map of the clinic and the matching door key: "Next, there is only waiting." ”

As for whether this area surrounded by forests leads to other places, it is unknown.

The doctor himself could not escape, and there was naturally no information to talk about.

After a while, the doctor recovered a lot from the effect of the medicine, and said with a sweat: "Okay, I'll try to remember, escaping won't solve the problem, this is the information I wrote down as requested, and I will try to tell you everything about this boy......"

Cao Zhengfei held the candle in his hand and handed two pieces of paper to Fang Liang and Lu Ming: "This is the current simple map of the clinic, after you went out, we found wooden planks and nails, and most of the doors and windows that can be used to enter and exit have been sealed. ”

"If we want to have a more peaceful life tonight, we'd better narrow down our range of activities and only move inside the 3 rooms with closed doors and windows, so that we don't get blocked by monsters and reduce the fuel consumption of the overall lighting."

"If we had lit up the whole clinic, the fuel might not last long, so we had already moved the lights, fuel and so on to the right places in advance. It's still a little bit dark, and there's still time to revise any objections. ”

"Just do as you say."

Lu Ming and Li Xiaoyu went to check the closure of the doors and windows, Fang Liang got the doctor's handwritten report, and entered the hiding place with the other two.

The so-called hideout, in fact, is three connected wards with holes in the walls, reinforced with planks and nails, leaving only two movable doors that are not sealed.

Fang Liang looked around, the medicines here had been plundered, and all that was left were some medical instruments that ordinary people didn't know how to use, or cabinets that weren't worth the effort to dismantle, bed supplies that every household had, and so on.

Li Xiaoyu and Cao Zhengfei were not idle during the day, they first transferred all the remaining usable items in the clinic to the third room, and then made room for the doctor to make room for him to refine the Heavenly Mushroom and trade with the "survivors" in the town.

"At least there are beds, sofas and a few chairs, so you don't have to lie on a cold, hard wooden floor at night."

Fang Liang pulled a chair and sat down relaxed, and his teammates were in charge of other things, so he began to study the doctor's handwritten report.

At first, the villagers tried to escape, but after all else had been tried, the villagers could not bear the horror of starvation caused by the overall reduction in food production, so they decided to cut down the forest and forage for wild vegetables, and cut down as many escape routes as possible.

However, both sides of the road leading to the city were all woods at the beginning.

When the forest grows wildly, the entire road is swallowed up by the trees on both sides, turning into a wall of trees with an almost solid structure, and even tank shells cannot penetrate the thick barrier of the tree wall, which can be said to be an insurmountable obstacle in a sense of the game map boundary.

It is not necessary to let the heavens and the earth be unspiritual.

In order to survive, the villagers began to investigate the depths of the forest in reverse, and then they found mushrooms on the trees that had been cut down.

The content of the doctor's report did not surprise Fang Liang, the doctor did not know much about the curse itself, and almost all of them relied on a set of miscellaneous recipes that were integrated day by day, but he himself had a lot of research knowledge about the Heavenly Mushroom.

Palaches, that's how the doctors call those poisonous mushrooms of paradise.

"Cellulose, the most widely distributed, abundant and readily available polysaccharide in nature. If certain reaction conditions can be met, cellulose will react chemically with water to produce glucose that can be quickly absorbed and utilized by humans to sustain life and energy. ”

"Livestock such as cows and horses can digest cellulose and can gnaw tree bark for a living, but it is difficult for humans to do this because the human digestive system does not produce large amounts of the enzymes needed to digest cellulose."

The doctor himself had no choice, and his food reserves were extremely limited, so he had to follow the town's instructions and start researching how to break down cellulose, how to make humans process cellulose, and how to use the symbiotic relationship between other organisms and humans to obtain food.

In other words, if humans could eat trees directly, there would be no more food problems and famine problems in the world.

Fang Liang raised his head and looked at the doctor's embarrassed expression, he was holding a stack of thin, neatly cut soft strips on the table.

The doctor pushed his eyes, rubbed his red nose that was about to be scratched, and said, "Ants can digest cellulose because there are flagellates in ants, which can secrete cellulase and cellulosidase. ”

"Fungi are also able to process cellulose, such as the common Trichoderma, Aspergillus, and Penicillium fungi. However, they are very slow to digest, and in my experimental studies with paraches, I found that this mushroom can produce a large amount of cellulase, and the mushroom itself is not very easy to digest, so it can ...... to a certain extent It maintains a parasitic and symbiotic relationship with humans. ”

Li Xiaoyu changed into investigator's clothes, and happened to hear Fang Liang and the doctor talking about this matter, he bluntly disdainful: "Really, it sounds extremely disgusting, thanks to you guys who can figure it out!" ”

"It would be disgusting enough if a person took off his clothes and had a dense festering mass on his back and said that they all had small mushrooms growing on them, or the kind that would break when they touched the mushroom lid. People who are timid and have a phobia of density are afraid that they will vomit on the spot at a glance. ”

"If you add to this fungal invasion and infection, the skin is keratinized, scaly, dry and cracked, and the itching is unbearable, unable to sleep, and self-scratching...... Believe me, those who are parasitized by mushrooms will definitely be out of the human realm in terms of appearance. ”

Fang Liang looked at the doctor again, and the doctor hurriedly defended: "At that time, there was really no way, there was no food, people couldn't starve to death, everyone was hungry and had to eat people, how could it be so much!" ”

"The logs that were cut down and placed in the forest quickly grew a large number of paraches, and the villagers collected these mushrooms and cooked them for a long time with other found vegetables and meats, which temporarily solved the food problem."

Fang Liang flipped through this report: "The mushroom itself is difficult to digest, and there are certain hallucinogenic toxins, people who have eaten mushrooms for a long time and have not been able to digest the mushrooms may have a large number of mushroom products in the digestive system, which accumulate and remain like stool, so there are problems?" ”

The doctor's face was embarrassed, and it was obvious that this memory was also an unbearable nightmare for him: "No, normally, as long as the human digestive system and immune system function normally, just eating mushrooms or food poisoning, it can recover. ”

"Although I am not a famous doctor, I also understand this medical knowledge, and those who eat bad stomach want to ask me to help induce vomiting, enema and gastric lavage, and I can still do this. Cooked mushrooms cannot infect a living person in the intestines, they are either spit out or excreted early through the stool due to some properties of crude fiber. ”

"At first, I thought so, until someone steamed and processed the parache into a high-purity mixture, bypassing the human digestive system and immune system, and injected it directly into the body......"
