"It's on, it's on." Although Yang Heng has done this action more than 100 times, but every time there is a fire, the children still cheer, to know this scene, but it is much more dazzling than the lighter of later generations, what match scene, Yang Heng is holding a bow, drilling wood at the end of the use, surrounded by a group of children, two or three minutes later, slowly drilling wood began to smoke, at this time the children are holding their breath, they are afraid of blowing away the smoke, and affect the occurrence of the flames, when there is a spark, Naturally, it was time for Xiao Niang to perform, she would take some very broken wood chips, and slowly put them in the place where Yang Heng drilled out of sparks, and blew them in the distance with her mouth, and then the flames came out, and then there was a burst of cheers from the children, you said that this scene was exciting or not.

At this time, not only the children hurried to the excitement, but Feng Bo felt excited, to know that every time he drilled wood to make fire, it would take half a day, tired and half dead, before he would drill out of the fire, generally drill out of the fire, he will not extinguish it, if it is extinguished in bad weather, then you need to find a neighbor to borrow the fire, otherwise it is difficult to drill out of the fire again, because the more anxious, the more it is impossible to drill.

With the cheers of the children, Yang Heng threw some wood into the fire, and when a few thick wooden strips were ignited.

"Everyone, stand back, look at it, my trick is coming." As he spoke, Yang Heng threw the burning wooden strip into the mud pond in front of him, at this time he didn't care whether the front would catch fire, but cared about his younger brothers and sisters, he was still afraid that the distance would be too close and hurt his younger brothers and sisters, fortunately, at this time, the biogas produced was not particularly thick, and there were only dozens of flames in the mud pond, all of which were blue flames.

"Look, Xiao Langjun, I said this is a cursed place, this flame is also blue, when have we ever seen a blue flame." "Well, yes, yes." The children were also frightened and pale, and they all nodded and looked at Yang Heng.

"I lit this fire, and this flame is blue, what curses are not cursed, do not frighten the child, you see, where there are a few birds, and a hare burned to death, see if I will bring it to you and taste it."

As soon as Yang Heng said this, the children immediately stopped being afraid, and if they still believed in Yang Heng, "Brother Heng, hurry up, hurry up, we want to eat, we want to taste the difference between the food burned by the blue flame."

What's the difference, is this muddy pond so easy to enter, Yang Heng looked around, and then went to the vicinity and chose a small tree, and directly broke it, took it back, and then broke it in half, and then burned the two ends out of a pointed shape on the fire, and bent one end out of an arc, and then drilled a few eyes into the tree with a bow, and then used the bark to pass through these eyes, and tied the two sections of trees to his feet.

"I know that Brother Heng is going to make snowboards, but there is no snow here." Xiao Niang shouted, and wondered again, there is no snow, what does Brother Heng do with skis, Yang Heng continued to find two long branches, just stepped on the two sections of trees, and walked forward directly.

As soon as he stepped into the blue mud pond, he immediately pushed the branch in his hand forward, and his body quickly slid forward with the trees under his feet.

"Ao, it turns out that Brother Heng is not skiing, but mud skiing, and then we have a fun project again." Hearing the words of the little lady, Yang Heng was stunned, and almost fell directly under the mud pond, this little lady is really good at drawing inferences, but it's terrible, she has to be optimistic in the future, and she can't just let her play anything too dangerous.

On the side of the burned bird, as well as the edge of the hare, Yang Heng squatted, picked it up, and then turned around gorgeously, but the turn did not turn around, but it stirred up a burst of mud, and a foul smell spread, which was the smell of some leaves that had not been fermented.

"Okay," it was such an action, which also aroused a burst of cheers from the younger brothers and sisters, and soon Yang Heng jumped out of the mud pond.

"Little lady, I can tell you that you can't go into this mud pond, look at this piece of wood." As he spoke, Yang Heng casually threw out a piece of wood on one foot, which slid on the mud for a distance, and then slowly sank in, and there was no shadow directly.

"If one of you is not careful, you will fall into it, and you can't save it, even if you pull your arm, you will pull your arm down, and people will still fall into it." Yang Heng directly threatened, Yang Heng was not afraid that Xiao Niang would lie to her when she was older, and when she was older, she would calm down, and Xiao Niang was still very sensible.

"Well, if you don't play with mud, we won't be slippery Brother Heng, don't worry, otherwise there will be no little lady." Xiao Niang looked at the sunken wooden block in the distance and said with a pale face, this time it really scared her.

"Okay, little lady, as long as you don't play with the mud pond, there's nothing to do, don't be afraid, there's no curse here, it's just that these mud bars are too thin, people can't stand on them, and I don't know how deep it is under the road."

"Well, well, I remembered, did you all remember it, you must listen to Brother Heng."

"Well, don't be afraid, let's taste the food that comes out of this blue flame, but it's too ugly to be cooked yet, let me bake it for you again, and you can eat it."

"Brother Heng, Brother Heng, I have salt here, cumin powder here, star anise powder here, and ......" Yes, these are a few foodie brothers, but they have brought all the spices.

"Well, it's so fragrant, but, Brother Heng's food is no different from the usual baked food, by the way, we're hungry, let's go back." "Okay, go back, Feng Bo, then you will take a few farmers here to dig up the mud in these mud ponds, and use them in the fields after drying them on one side, they will become very good fertilizer, and they can also kill insects, you have also seen, when you come, you must bring torches, and then throw some torches far away, let the inside be finished and then go in, if it is too deep, you can bring some bamboo rafts over, by the way, leave me some moist mud out, I can use." Yang Heng naturally wanted to make a biogas digester, which was used for seeding, otherwise Yang Heng would not know where to find those biogas-making bacteria.
