"There's something new in the Lord's house." As soon as the villagers shouted, some people took turns to come to Yang Heng's house to see the strangeness, especially at night, the methane lamp was lit, but it was brighter, it was brighter than the stars in the sky, what kind of metaphor is this, are the stars in the sky bright, that is, they just see a little light, and they can't illuminate anything.

However, if you look closely, this biogas lamp is really a bit similar to a star, because it is too bright, after looking at it for a long time, it is full of stars.

At this time, the so-called biogas lamp, naturally is the kind of lamp in the form of a torch that bubbles up on a pointed head and then burns directly, if you say that the kind of biogas lamp of the real later generations, Yang Heng really does not have the ability to make it now, first of all, you must make a kind of grille, this is the place where the biogas lamp burns and glows, after the biogas lamp burns, this grille will bulge, like a light bulb, and there is a glass cover outside, now there is not even glass, how did the glass cover come from, so just use it, But it's much brighter than candles and oil lamps.

The villagers saw it, and the soldiers in the natural barracks also heard about it, and they all came out to see it, so for a period of time, there was an endless stream of people from Yang Heng's family.

"Little sister, we miss you, why don't you go back to the city to play with us." Yes, Yang Heng's family was a little quiet just now, and these two came again, saying how these two came here, this is a bit long.

You must know that Li Er, as an emperor, put an army not far from him, and he is not very relieved that he will be taken care of by the people he wants to believe, not to mention that Li Er doesn't know too much about Yang Heng's father, who knows that Yang Dao will not be so careful.

Naturally, Li Er arranged secret guards near this army, and even there were secret guards in the army, this Yang Heng also analyzed with his father, whether it was in front of or behind people, he must not do anything, or say anything excessive, fortunately, none of Yang Heng's family likes to drink, so these things are avoided.

Some of the things that Yang Heng did before, Li Er is still very satisfied, this army has been fighting with him for a long time, to be honest, Li Er still has feelings for these people, what is the establishment of Xintang Village to Ten Villages, Li Er is still very satisfied, it is the matter of the muddy pond in front, Li Er also heard about it, and even he asked carefully about Yang Heng breaking the curse with great interest, until the most Lu did he know that this is a natural phenomenon, not a curse of gods and ghosts, So the heart that he was carrying was also relaxed.

He also specifically asked some scholars about this kind of muddy pond to ask about this kind of muddy pond, and it can be regarded as a real understanding of God, although the Confucianism does not understand, but they are involved in a wide range of books, and there are occasional records of this kind of thing in the books.

When Yang Heng arranged for people to go to find coal with great fanfare, Li Er, who was heating himself, once again cared about what this coal was, until Yang Heng found the coal, "Isn't this peat, Guanyin, what do you say that kid wants this kind of peat for, this peat can be burned, but it's useless, the iron made from it is too brittle, is this peat still useful?" "Erlang, don't you know what to do when Yang Heng makes it, anyway, he found peat, it will definitely be used, you just wait and see." "Ha Luha, yes, it's me who is in a hurry."

Next, what coppersmith did Yang Heng's family buy, Li Er also knew Lu Dao, that is, Yang Heng's family bought these coppersmiths and tinsmiths, Li Er also intervened, how did he interfere, he naturally knew which one of Lu Dao was convicted again, so he secretly reminded Yang Heng's housekeeper, so that the housekeeper could buy people as soon as possible, even other people were also warned by Li Er's arrangement, otherwise, the housekeeper is Zhilu Dao, and it is difficult to say that he can buy it.

I don't know where this Li Er has such a big interest, he always cares about everything in Yang Heng's family, no, Yang Heng's biogas digester has just come out, and Li Er knows it.

"What, take a pile of mud from the mud pond as seeds, and throw it into a pool with dung, weeds, and leaves, and then a whole combustion gas is produced from it, and it is the same as the gas in the mud pond, so the kid has mastered this gas?" Li Er's eyes widened and he listened to the report, "No, I want to see for myself." "Your Majesty, you don't need to be yourself, have you forgotten our two precious girls, they were also a little wild some time ago, and they have been talking about what little lady and little lady, otherwise, let the two sisters go and have a look, and then come back to report to you."

"No, both of them are big girls, how can they show up, no." Li Er objected, but the more he said, the more he had no confidence, this was not to let the two of them go to see others, but to go to play with Xiao Niang, it didn't seem to be a show of face, "Your Majesty, how can this be a show up, you must know that Xiao Niang is the best friend of the two of them, and she is also a classmate of the two of them." The eldest grandson was very understanding and solved the problem for Li Er, this is the reason why the two sisters appeared in front of Xiaoniang and Yang Heng, since they want to see the biogas lamp, and the biogas stove or something, they naturally want Yang Heng to explain.

When they shouted as soon as they entered the door, they naturally stuck out their tongues in unison, this is not a long time to hold back, they are a little stuffy, otherwise how could it be.

"Princesses, you see, this is the methane lamp, and we can only see a pale blue flame during the day, and only at night can it show its effect." Yang Heng vigorously unscrewed a valve on the side, and then lit the torch with a fire source, and it burned like a gas welding gun.

"Also, two princesses, you see, this is a biogas stove, and the biogas lamp is exhausting, just a pot is placed on it, and there is a shelf on the side."

There was no need for Yang Heng to move the switch hard, because at this time, water was boiling on the stove, which was burned for the workers outside. The workers are building new houses, that is, the houses of the villagers in the west of the village, and some guards also ask for houses to live in this village, the name of this village is called Yangjia New Village, and naturally the old village is still the village in the mountains, but it is not called the old village, it is still called Yangjia Village.
