Gu Qiancheng and Qin Shiyan were not very afraid of this snake forest, and they had figured out the situation in the snake forest in the past five days.

Those snakes for some reason, can only be wrapped around the tree, as long as a way out, the snakes in the snake forest will not be a problem, they can pass the guò lightly, the more troublesome is the snake cave behind the snake forest.

"Why don't we set it on fire?" Gu Qiancheng gave very constructive advice.

They have a fire in their hands, and it is not too difficult to put a fire, but it is difficult to put the fire behind the snake forest.

"I'll try." Qin Shiyan couldn't think of a better way for the time being, so he could only try to attack with fire.

The two collected a lot of dry firewood, Qin Xiaoyan broke it into a big bag, and then carried this big bag through the snake forest, threw the hay to the snake cave, and the fire was also thrown over.

"Puff ......" the fire came into contact with the hay and immediately ignited, and the wind blew quickly ignited the surrounding hay, but the fire was very small, and it was okay to roast one or two snakes, and to kill the snakes in the snake cave, it was definitely a joke.

Qin Shiyan shook his head, used the branch as a sword, cut down a few trees and threw them into the snake cave, but the leaves were burning, but the branches that had just been cut down were not easy to burn, and the fire was extinguished in a short time.

Qin Shiyan didn't give up, he found more hay and cut down more branches to help burn, so the fire immediately started, but the problem came again......

The snakes in the snake cave were affected by the high temperature and slowly crawled out, the whole mountain was full of snakes, and Qin Shiyan and Gu Qiancheng couldn't set fire to the entire mountain.

"It seems that the fire attack will not work, and we will not be able to burn the whole mountain." Gu Qiancheng looked depressed.

They don't have anything to support the combustion, and there is no way to set fires on a large scale.

"Well," Qin Shiyan nodded solemnly, thinking of the picture he had seen before, his brows furrowed slightly, and after pondering for a moment, he said: "Those snakes disperse immediately when they encounter the fire, and come back immediately as soon as the fire is extinguished, they seem to be inseparable from the snake cave, or is there something behind the stone gate that makes them have to stay outside?" ”

"Guard, you say?" When Gu Qiancheng heard this, he couldn't help but raise his eyebrows.

Are snakes that smart?

"It's not like a guard, it's like you're waiting for something." Qin Shiyan thought of the reaction of those snakes, and had a vague guess in his heart, but he didn't dare to be sure, it was difficult to say it now.

"I'm not interested in what the snake is waiting for, I just want to get out right now." After being trapped for seven or eight days, Gu Qiancheng became more and more anxious.

People outside don't hear from them, so they might think they're dead. She is okay, she can't affect the overall situation, but Qin Xiaoyan is different, he is now the emperor's grandson, and he has not shown up for a long time, so if someone with a heart finds out, it will definitely cause turmoil in the court.

"There is no other way for the time being, we can only start from that stone gate." Qin Shanyan tried to take two steps forward, but found that as soon as he stepped forward, the snakes of the snake forest began to spit letters at him, full of precaution, and as soon as he retreated, the snakes on the tree quieted down again.

After trying this a few times, Qin Shiyan said boldly: "Qiancheng, maybe there is something in this place where we are standing so that the snake can't find our existence." ”

They thought it was a matter of distance. If it is too close, the snake will think that it is threatened, so it will take a defensive posture; When they were far away, the snakes did not care about them, but now it seems that it was not the snakes who defended them, but they retreated, and the snakes could not find their existence.

When Gu Qiancheng heard this, he also took a step forward, and found that things were really as Qin Xiaoyan said, "Isn't it this place, what is there in this special place?" ”

"Look for it."

Qin Shiyan and Gu Qiancheng searched separately, and the two of them pulled out these two fields, each of which was a different grass, and tried stones and other things one by one, but none of them were.

"We're pulling out all the grass." Gu Qiancheng was busy all day, so he was too tired to sit on the ground.

Qin Shiyan was a little better, but there was also fatigue between his eyebrows and eyes.

The longer they stay in this ruined city, the less likely they are to get out.

Of course, the more likely it is that something will go haywire.

"If it's not grass, it's not stone, so what would it be?" Gu Qiancheng grabbed a handful of grass casually, pulled it up with the soil, and the black soil fell on his body, rolled around twice and then fell to the ground......

Gu Qiancheng's eyes widened as he looked at the nail-sized piece of dirt, "Qin ...... Qin Xiaoyan, I seem to have found out. ”

"What?" Qin Shiyan turned his head and asked.

"Look...... Soil, isn't this soil different? Gu Qiancheng pointed to the dirt on the ground, his eyes brightened.

"Dirt?" Qin Shiyan glanced at it and didn't notice anything unusual. Of course, with His Royal Highness Qin's little cleanliness habit, he wouldn't reach out to touch it.

"It's dirt. You see, the earth is red. Gu Qiancheng was not afraid of getting dirty, so he picked up the small piece of soil that fell at his feet and handed it to Qin Xiaoyan, "Red soil is not common, maybe it is really a problem with the soil." ”

"Really?" Qin Xiaoyan was not sure, but Gu Qiancheng was interested, "I don't know, but we can try it and dig up the soil in front of us to compare." ”

Gu Qiancheng said just do it, grabbed a stone and walked forward, stopped at the distance where the snake would find them, and dug out a piece of soil, which was also red, but ......

Gu Qiancheng carefully smelled the taste of the two lands, and was sure that the soil composition of the two lands was different, and even tasted it slightly, and the pH of the soil in these two lands was also different.

Gu Qiancheng said in surprise: "Your Highness, the soil of these two lands is really different, maybe it is really a problem of soil. ”

"Really?" The corners of Qin Shiyan's mouth twitched slightly, feeling that the whole person was not good.

Gu Qiancheng is already hungry to the point where he can even eat soil?

"What's wrong with you? Not happy? Gu Qiancheng realized that something was wrong with Qin Xiaoyan, and when he thought of Qin Xiaoyan's little cleanliness, he couldn't help but smile and said, "Your Highness, you won't be unable to accept it, I'll taste the taste of the earth, right?" ”

Well, Gu Qiancheng herself couldn't accept it very much, if it weren't for the lack of instruments and the inability to analyze the composition of these two kinds of soil, she wouldn't have done it.

"Ahem, it's not ......" Qin Shiyan turned his face away in embarrassment, and hurriedly diverted the topic, "Since you think that the snake attack does not attack us, it has something to do with the soil, what should we do next?"

Gu Qiancheng laughed and didn't say anything more.

When she was trained by the quilt car, she ate mud from time to time, in order to survive, Gu Qiancheng never cared about this little problem.

Gu Qiancheng raised the soil in his hand and said, "If it's really because of the soil, we'll use this soil to arm us, and then try to cross the snake forest." If the serpents of the serpent forest do not attack us because of the soil, the serpents in the serpent cave will not attack us either. ”

In other words, they have to roll in the mud and get their whole body covered in mud before they go to the snake cave......
