Li Ge took out a bunch of keys to open the iron door, walked into the stone-paved courtyard, and opened the door of the earthen walled house.

Yuling followed in, there are kitchens, living rooms, bedrooms, and some living utensils are also complete, so it is not a problem to stay here for two days.

It's already 4 p.m., and in another three hours it will be dark, and the panic village at night may not know how dangerous it is, so it's better to wait until tomorrow to go out.

"I'll go to the well to get water and come back to cook, you can rest first."

"I'll go too." Yuling stood up from his chair and didn't give him a chance to be alone.

After dinner, Li Ge made the bed.

Fortunately, the two bedrooms are connected, otherwise Yuling would have planned to sleep in the same room with Li Ge. The keywords of uninhabited, deserted village, and big snake are grouped together, and it is not a bad thing to be cautious.

Early the next morning, I washed my face with clean water, ate some convenient food, locked the door, and Yuling and Li Ge set off.

"When you came back during the Qingming Festival, who were still living in the village? Let's go and see how they're doing. ”

Walking around the village, there are only three families in the whole village, mostly elderly people and women.

Li Ge and Old Man Li were talking about the Qingming Festival, "Aren't you going to move to the city?" Aren't you afraid that there will be a big snake? ”

"I'm afraid. Our fields are here, and we can't go. The old man shook his head and coughed.

"Uncle Li, you coughed so badly that you didn't go to the doctor?"

"I bought a cold powder, a small problem, it doesn't get in the way." The old man waved his hand.

Yuling and Li Ge both realized that Old Man Li was most likely infected with pink eye, but except for Old Man Li, no one in the other villages had any symptoms of pink eye.

This shows that people in the village do not necessarily have pink eye.

Bidding farewell to Old Man Li, Yuling followed Li Ge and walked back.

"You and Uncle Li seem to be familiar with each other, have you been in contact with each other on the Qingming Festival?"

"Hmm." Li Ge nodded, "Let's go fight the big python together." ”

"Have you been in contact with the rest of the village?"

Li Ge thought for a while, "There should be." Because the python was killed that day, everyone in the village came to watch. ”

This shows that it is not a matter of contact infection, Yuling pondered.

If I remember correctly, Li Ge, Li Ge's father, Li Ge's uncle, and Old Man Li all participated in the killing of the python.

Could it be that the source of infection is a python?

"What about the body of the anaconda? How did you deal with it? ”

"Take the fire and burn it."

"I thought you would eat snake meat?"

"No one dares to eat after eating people."

In the later stage of pink eye, it is only transmitted by bodily fluids, and whether the python is the source of infection or not, just ask to know. "So, you've all touched the serpent?"

"Yes. After we killed the python, we carried it from the mountain to the village. ”

It seems so! The source of infection is a large snake, which was infected because it came into contact with a large snake.

But none of this matters, what matters is why Li Ge is not infected. No, to be exact, Li Ge was also infected, but pink eye mutated in him.

Theoretically, the biggest possibility is that Li Ge has his own antibodies. However, in fact, experts are still not sure that pink eye is caused by a viral infection.

Moreover, Li Ge's father and uncle were also infected with pink eye, from a genetic point of view, the possibility that the son has antibodies and his parents do not have antibodies is very small, of course, it is not ruled out that the possibility of acquired antibodies is not ruled out, but the acquired antibodies must be due to the stimulation of the external environment.

Therefore, Yuling deduced that it was external factors that caused the pink eye on Li Ge's body to mutate, and it was for this reason that Yuling ventured here.

"Li Ge, you recall carefully, after you returned to your hometown during the Qingming Festival, did you use or eat anything special?"

"We came back to worship our ancestors on the day of the Qingming Festival, and we planned to go back in the afternoon after worshipping our ancestors, but that day we went to look for the missing child, and found that it was dark and very tired, so we ate some fruits and snacks that we brought. Relatives wanted to keep us to eat, but we didn't, and returned to Zhangzhou overnight, afraid of more than one big snake. ”

"Have you ever been exposed to anything special?"

"Orochi, ......"

"Apart from this, if you think about it, are there any others? …… This is important. ”

"......" Li Ge groaned, and suddenly remembered something and said loudly: "I also ate wild fruits, the village chief organized everyone to go to the mountains to find the missing child, I was thirsty on the road, I picked wild fruits to eat." ”

Intuition tells Yuling that wild fruit is the cause of the mutation of pink eye.

"Let's go, you lead the way, and we'll go find the wild fruit you said." Yuling stopped Li Ge, "Did you bring a weapon?" ”

She opened her backpack, took out a pig-killing knife from it, and unwrapped the wrapped strips of cloth.

"Brought it." Li Ge took out a short axe from his backpack.

Walking along the winding path, the weeds on the side of the road are submerged to the thighs, and it is really worrying that a snake will emerge from the weeds.

"It's a big mosquito." Li Ge slapped a wild mosquito to death and handed it to Yuling, blood stained his palms.

He flipped through his backpack, took out the toilet water, and sprayed some on his body, "Do you want it?" ”

Yuling nodded, took the bottle of toilet water, and sprayed some on herself. Although she had expected it and wore it very tightly, where could the summer clothes go.

Walking into the shadows of the woods, there is no sunlight, and it is instantly cooler. Looking deeper into the woods, it looks a little eerie.

"Let's go." Fish bell road.

The two of them continued on their way, coming to a stone wall, where the sunlight was blocked by the dense foliage, and the air was somewhat humid.

The surroundings are very quiet, and the chirping of birds and summer cicadas before has all disappeared here, which is a little abnormal.

"Be careful." Yuling reminded Li Ge in front.

"It's almost there, up ahead." Li Ge's face was happy.

In front of it was a strange clearing, where the sun shone down unhindered, and the surrounding trees were entwined with thick vines that covered the tops of the trees and hung straight down like a green waterfall.

The clearing, like the mouth of a dense forest, contains only a half-man-tall tree, with fruit the size of a mineral water bottle cap on its branches.

"How so?" Li Ge looked around in surprise, the surrounding scene was completely different from his memory, "The last time I came, there were obviously a lot of plants. ”

The fruit has traces of insect damage and should be non-toxic.

Yuling took out a bottle of canned fruit from his backpack, poured out the fruit in the glass bottle, and washed it with mineral water.

There were four partially yellowed fruits and five half-yellow and half-green fruits on the tree, and considering that this place was very strange and most likely would not come again, Yuling picked all 9 fruits and put them in a bottle.

"Be careful."

Li Ge's shout sounded in his ears.
