"Hahaha." The dragon spirit raised the arm wrapped around the winged fire snake and smiled, "The ghost has been caught by me, this is it." ”

Cang Jizi saw that it was a winged fire snake, and he was very puzzled.

The dragon spirit ripped the snake from his hand and explained, "It's not the ghost pressing the bed, it's the bird snake that slipped away, and you didn't tie its mouth tightly, so it secretly sprayed poison gas at us." ”

"It poisoned you, and it poisoned me again, thanks to my timely detection, otherwise the two of us would have died in our dreams in a daze."

"Won't it?" Cang Jizi couldn't believe it, his eyes were wide and he said, "It ran out and didn't run away, but instead released poison while we were asleep?" Are you talking about snakes or people? ”

"Don't believe me, do you?" The dragon spirit knew that he would not believe it, and it was hard to believe anyone who told this, so he asked, "Are you feeling dizzy and nauseous now, and your body is weak?" ”

Cang Jizi felt it, shook his head and said, "No, I was too nervous just now and felt very tired." ”

"No way, I'm less poisoned than you, and it's still uncomfortable."

"I really don't feel anything." Cang Jizi got out of bed and jumped a few times on the ground, and her movements were normal, unlike the uncoordinated movements of the dragon spirit.

"How so?" The dragon spirit felt that something was wrong, approached Cang Jizi, sniffed his face, and then lay on the ground to look for something carefully.

He looked at it for a while, and couldn't help but wonder: "There is no smell, and there are no traces of snakes crawling, which means that the winged fire snake has not poisoned Cangjizi." ”

"The house is well ventilated, and the snake's poisonous gas can't affect Cangjizi. He wasn't poisoned at all, how could he be caught in a nightmare? ”

"It's too much of a coincidence." After thinking about it for a long time, I can only barely explain it with reasons such as environmental weather.

Look at the sky, it is dark and I don't know the time, but I heard the sound of birds in the jungle, which means that it is almost dawn. I simply didn't sleep, lit the fire, and studied the winged fire snake in my hand while thinking about things.

More than ten hours have passed since this winged fire snake was caught by the dragon spirit, and it has not spewed fire again.

It didn't take long for the dragon spirit to roughly guess the reason why the winged fire snake was spewing fire.

It is said that there is a fire-breathing fish in nature, they can spit a phosphorus-containing substance onto the surface of the water, and the phosphorus will burn when it comes into contact with the air, thus turning into an incendiary bomb.

There is also a beetle called the African gas beetle, which stores two chemicals in its body. When it simultaneously injects both substances into a special "combustion chamber", a toxic, high-temperature liquid is formed, which is then ejected from the vent in the tail.

The main reason why the winged fire snake can breathe fire is that there is combustible gas in its body, but the cause and composition of this combustible gas are different from the above two creatures.

Most animals can produce combustible gas, which is a 'fart' with a bad reputation. It is released when microorganisms in the animal's intestines break down food and contains a certain percentage of combustible gases, mainly hydrogen, methane, and hydrogen sulfide.

There should be a large number of bacteria in the body of the winged fire snake that can produce combustible gas, and the fermentation is usually controlled in some way, and when it is used urgently, it will be released, and a large amount of gas will be quickly produced.

"It's just that I have a biogas digester in my stomach, and it's good to use as a lighter."

The dragon spirit smiled, stroked the belly of the winged fire snake and said, "It seems that it takes a lot of food to breathe fire, and if you spray it twice, your stomach will be empty, and you won't have any strength." ”

He shouted to Cang Jizi: "Don't sleep, go, go outside and catch a few live creatures to feed this guy." ”

Cang Jizi fell asleep again, and didn't want to go: "Feed it again, didn't you say that it wanted to kill us just now?" When you're fed, you'll have a few fires, and you won't want to live in this house. ”

"Less nonsense." The dragon spirit kicked him and said angrily, "Don't believe it or not, I'll beat you up?" ”

"I know how to bully the weak." Cang Jizi snorted angrily, and came back after going out for a while, holding a chopstick-long lizard in his hand and throwing it in front of the dragon spirit.

The lizard was half-crushed to death, and was dying on the ground.

The dragon spirit grabbed the tail of the winged fire snake and put it on the ground, and the winged fire snake sniffed the lizard for a long time before opening its mouth and swallowing it, still looking around with dissatisfaction.

The dragon spirit grabbed it and said, "The guy next to me is too lazy, he only found you such a little food, if you don't breathe fire again, it will be enough for you to be full for several days." ”

Cang Jizi lay back on the mat, turned over and reminded, "Remember to tie its mouth." ”

The dragon spirit thought about it, and made a small dragon out of the bark and put it on the snake's head, and tied it tightly around the neck with a thin hemp rope.

The winged fire snake had to ignite the gas by striking its porcelain lips, and with the restriction of this halter, its mouth could only open a slit, and it could no longer knock out the sparks, neither fearing it suffocating or spitting fire.

"Fresh food can't be fermented, at least it's almost digested to produce enough gas, and it will take some time."

The dragon spirit put the winged fire snake into the basket, and this time he didn't dare to take it lightly, and tied the basket lid firmly with a vine.

The two chatted a few words, Cang Jizi fell asleep again, and Long Jing sat quietly, looking out the window and thinking about the future arrangements.

The words of the great wizard made him recognize the reality like a slap in the face, and he planned to truly integrate into the Longze Department and really contribute to the tribe.

As a traverser, the dragon spirit knows that the knowledge he has can make earth-shaking changes in the lives of the villagers, and can quickly improve the level of productivity and civilization.

There seemed to be so many things to invent that it was difficult to choose, and he was ambitious enough to do it, but when it came time to implement it, he found that there was nowhere to start.

The means of production in this era are too scarce, and the difficulties are much greater than imagined! Harsh environment, backward tools, scarce information, low-quality population...... All kinds of restrictions almost frustrated his ideas.

For example, the table salt mentioned earlier. The refining technology is simple, but there is no salt water and salt mines, too few people and dangerous jungles to carry out large-scale exploration, and empty technology is also dry.

Therefore, although there are many options, it is difficult to achieve those that require a little more complexity, let alone advanced technologies such as metal smelting, which are complex processes.

Excluding everything he could think of in his mind one by one, and in the end there were only a few left, and the dragon spirit was disappointed, so he could only comfort himself: "Take your time, when you lay a good foundation, it will be much easier to develop again." ”

Soon the sky turned white, the village began to cry, the rainforest came to life, birds chirped, frogs chirped, apes and tigers roared.

Long Jing made a plan, shook his spirits, twisted Cang Jizi's ears to pick him up, climbed down the rope ladder, and walked towards the village full of ambition.
