In late summer and early autumn, the climate of Mount Wutai was originally cool, and the grass and trees had begun to wither and yellow, so it was easy to set fires around. Eighteen people set fire to it at the same time, and the fire spread rapidly among the grass, and many snakes that did not have time to escape were surrounded by the flames.

Zhao Kuangyin is right, the fog and smoke make people can't open their eyes. The face towels of the Khitan warriors served a lot of purposes, and they continued to set fire with their hands free. The other three covered their mouths and noses with their clothes to avoid choking on the smoke.

Suddenly, a light breeze blew, and the fire burned bigger and bigger with the help of the wind, and the smoke was also carried away by the wind, and the surrounding fog became smaller and smaller.

......The fire suddenly became uncontrollable, swallowing everything that passed by, and the fire was accompanied by a 'crackling' sound.

What is surprising is that the stronger the fire, the stronger the wind, and in the blink of an eye, it burned into the distance, and at this time the fog has completely disappeared, and everyone looks at the direction of the fire, and their hearts are not sad.

"It's such a big fire~ It would be nice to catch a few snakes to roast......" The old man swallowed his saliva and said: "Master, how did you know that the wind would rise soon?"

This question was very curious to everyone, and it had been calm all the time, and there was no sign of wind at all. Why did Zongxin know that there would be a wind, so he asked everyone to set fire.

Zong Xin waved his hand and said: "You have made a mistake, it is not that the wind is set on fire, but because the wind will rise after the fire." There are too many explanations that you won't understand, just remember one thing, as long as the climate is cool, the wind will start when you set it on fire. But the fire must be big, and the bigger the fire, the stronger the wind. ”

"Can fire make wind?"

"There are so many things that fire can make, fire can produce light, smoke, ash, heat, and of course wind. So be good at using fire. Zong Xin's slight explanation made everyone notice that fire was so useful. If you think about it, isn't life all about fire up to now? But the more ordinary things are, the easier they are to be overlooked.

The fire is still spreading, but it is much smaller, and the hill is almost half burned. At this time, there were only ruins left around Zongxin and his party, and there was no trace at all. Most of the snakes failed to escape, and after being consumed by the fire, only a charred corpse remained, and there was no trace of snakes around except the scorched earth.

"Can you still find snakes?"

The demon took a closer look, then pointed to the northwest and said, "Over there, the fire is burning outward with us as the center, and the most snakes have been burned to death in this direction, and it is most likely a snake nest." ”

The demon took the lead, and the group headed northwest, and the fire was the first to be extinguished, because the fire was cut off by a small river. The demon looked carefully around the river, and then said excitedly: "It must be nearby, the snake also needs to drink water, but it likes a dry and ventilated environment." Therefore, the snake nest will be within a few hundred meters of the water source, carefully search on both sides of the river, and you will definitely find the snake nest. ”

Zong Xin looked up at the highest peaks of Wutai Mountain and said, "You don't need to go over, this water must be very cold, and the snake will not cross the river, so the snake's nest is here." Everyone spread out in a horizontal line and pushed up the river. ”

Zongxin's words worked very well, the Khitan warriors immediately dispersed, starting from the river, every two people could see each other at a distance of more than ten meters, Zongxin, Zhao Kuangyin, and demons were mixed in to take care of each other, and then a seemingly huge encirclement network went all the way to the north.

After crossing the two mountains, the terrain is getting higher and higher, and the temperature is getting colder and colder. At the same time, traces of snakes were found again. It is a pine forest, the pine trees are tall and straight, and the grass on the ground is green. The foliage was not dense and the sunlight was shining through the cracks, but the forest was very quiet and eerily quiet. It's the end of summer, and the pine forest should be very lively.

After reaching the top of the mountain, I finally found the traces of snakes. Stopped by the fire just now, a lot of time was wasted, and the group of snakes had already climbed to the mountainside of the third mountain.

From a distance, dense snakes crawl in one direction, from the bottom of the mountain to the mountainside, and then converge in a cave on the mountainside. These snakes come in a variety of colors and sizes, and several of them are very large as can be seen with the naked eye.

The fire frightened the snakes, and they all fled back to their caves. Strangely enough, it's cold, and snakes shouldn't have chosen this place as their nest.

"It's easy to find the hole, just rush in and catch them all. Zhao Kuangyin didn't expect things to go so smoothly, although there are a lot of these snakes, and even some of them are not small, but in the face of the martial arts masters sitting there, these snakes have only one way to die.

"Strange, how can snakes live in such cold places? "The demon has raised five poisons since he was a child, and he knows snakes very well, so he really doesn't know which snake likes to be cold.

Zong Xin suddenly smiled sinisterly, this smile Zhao Kuangyin and the Khitan warriors are very familiar, as long as Zong Xin sends out this kind of smile, someone will be unlucky.

"Don't be impulsive, let's wait for this group of snakes to go in first, prepare wet and dry firewood, and that's pretty much it. ”

The Khitan warriors immediately nodded and scattered to find what Zongxin wanted. There are a lot of pine trees nearby, and it is easy to find any kind of firewood you want, and you can quickly bring a lot of it.

At this time, the snakes also entered the hole, Zongxin waved his hand, and everyone ran down the mountain. The distance was quite far from the bottom of the mountain and up the mountain, but the speed of the wolf was extremely fast, and it didn't take much time.

After coming to the cave, I realized that the entrance of the cave was as high as two people, and the snakes had crawled into the depths, and there was no trace of the snake within a few meters of the entrance of the cave.

Zongxin put his finger in his mouth and took it out to measure the direction of the wind, and the wind was blowing into the hole.

"Put the firewood in the hole, where you can see, dry firewood on the bottom, wet firewood on top, fast. ”

Zongxin ordered, and sixteen Khitan warriors worked in pairs to prepare things in a blink of an eye. Zong Xin quickly walked to the firewood pile, took off the cloth bag around his waist, poured all the realgar in it on the top layer of wet firewood, and then carried the Sun Wuji True Qi on the dry firewood and immediately ignited.

"Go and stay away from the headwind, that thing is highly poisonous. After Zong Xin left the cave, he ran away, and the others were not stupid, so they immediately followed behind him and found a place against the wind to hide.

The demon said depressedly: "Husband, is it useful for you to do this? The poison of realgar is weak, although the snake is afraid of realgar, but it is not to death." If you want to smoke them out, you don't have to go that far. ”

"I~" Zong Xin said: "You have also studied the Five Poisons God Chapter, haven't you heard of arsenic?

"I know~ red letter stone or arsenic stone is refined, and if it appears red, it is called crane top red and is violently toxic, and if it is white, it is arsenic. What does this have to do with realgar?"The demon is a professional poison maker, how could she not know about refining arsenic?"

Zong Xin asked curiously: "Don't you know that realgar will also turn into arsenic after burning?" Don't underestimate realgar, although realgar is very toxic, but the smoke after burning is highly poisonous. No wonder you don't know...... After burning, the realgar will become smoke, and who would have thought that this smoke is also arsenic? Moreover, it is highly toxic and turns into air and inhales directly into the body, which is more powerful than eating it. ”

I can't believe it, the demon really doesn't know that realgar is arsenic after it is burned, and it doesn't even know that realgar is highly poisonous after it is burned. After refining poison for so many years, how could Zongxin, a monk who didn't understand poison at all, know these things?

Zhao Kuangyin gritted his teeth and said: "Zongxin, how much else do you have to hide from me? This eldest sister has been refining poison all her life, and she doesn't know that realgar will be highly poisonous after burning, how do you know?"

The demon was also about to ask, but he didn't expect Zhao Kuangyin to speak first. But everyone is used to it, because Zongxin knows a lot of things that ordinary people don't know.

"If you have the ability to kill me, I'll tell you if you kill me. "Zong Xin deliberately concealed that no one could do anything about him, but he didn't expect him to be a high-ranking monk who was a monk.

Everyone sighed and stared at the cave, although the wind was cutting into the cave, there was still some smoke coming out of the top of the cave, and the colors of these smoke were very complex, white, black, yellow, orange.

White and black are common, because the oil in the pine tree is very thick, dry firewood will naturally emit white smoke, wet wood will emit black smoke, as for yellow and orange should be the color of realgar burned. Are these smokes really poisonous?

Soon, smoke began to rise from some of the ground on the mountain, which is not surprising that there must have been other vents in this cave. However, these vents are small, and large snakes should not be able to escape.

The group waited outside the cave for a long time, but there was no response, and when all the firewood was extinguished, not a single snake escaped......

At this time, no one doubted Zongxin, if such a thick smoke was not highly poisonous, the snakes in the cave would definitely be smoked out. Although a fire was lit at the entrance of the cave, the snakes just now were not small, and they would definitely be able to break through the fire and escape. Since they didn't do this, there was only one possibility, the snakes had been poisoned by the poisonous smoke.

But the next problem is more troublesome, the cave is full of poisonous smoke, so how to go in to make sure that all the snakes inside are dead. Although there is air circulation in the cave, it is difficult to guarantee that there will be no poisonous gas left, and it is easy to be poisoned if you go directly into it.

"I have to find a way to go in and take a look...... The wind was so light that it would take an hour for the smoke inside to clear completely. Zong Xin said.

"Haven't you practiced the Five Poison Gods? Arsenic is not a powerful poison, so it's okay for you and the demon to go in directly. ”

"You know. ”

Zong Xin didn't want to explain too much, realgar burning is extremely toxic, the Five Poisons God Chapter was originally refined by the five poisons, and the five poisons are afraid of realgar, not to mention the toxicity after burning, it must not be solved.

The demon didn't say anything, just looked at Zong Xin with a puzzled expression, because arsenic toxicity is indeed incurable for ordinary people, but it is not fatal to people with advanced skills, let alone people who have practiced poison skills...... When I was a child, I ate arsenic as sugar. Maybe it was because the burned realgar was more poisonous than arsenic, and Zong Xin didn't dare to approach.

Or maybe Zong Xin didn't know the power of the Five Poisons God Chapter at all, and he thought that he could only cure the Five Poisons. Just tell him secretly in the future, don't let Zongxin lose face in front of so many people.
