Li Xiang laughed and said, "It's okay!" But now, our family can improve a bit, and tomorrow night we should make a little more hearty meal, and we should celebrate well! ”

Li Kang came back to his senses at this time, and nodded again and again: "Well, it seems that my son is really out of luck!" can get the princess's reward, that is how many people want to get it but can't get it. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 info By the way, the fireworks tonight are really beautiful, no wonder the princess rewarded so much at once! ”

Li Xiang shook his head and said: "Actually, this reward is not because of making fireworks, but the princess has to test the child's poetry skills, but fortunately, the child made two poems and passed this level." Finally, the emperor also specially prepared a sumptuous imperial meal, and the children feasted on their mouths. No, the child also brought back some imperial food from the palace, everyone can taste it! ”

After that, Li Xiang walked into the house, and from the wide cuffs, he found out the gold rewarded by the princess, as well as some imperial meals, mainly interspersed food and pastries, such as fried white kidneys, roasted belly, roasted duck breasts, moist chicken, moist rabbits, moxibustion cakes, etc.

It's like a trick, as soon as Li Xiang touched these things, Xue'er couldn't help but stare at Li Xiang curiously, she didn't understand, how could the young master hide so many things on his body?

Of course, they didn't know that Li Xiang was found out of the super 3D printer in his body, in addition to being able to print a lot of things, this super 3D printer has another function that is completely equivalent to a space artifact in a fantasy novel.

As soon as these things were placed on the table, not only Sanniang, Xiu'e and Xue'er couldn't help but swallow their saliva, but even Li Kang felt that his stomach seemed to be growling!

Li Xiang smiled and said: "Father, Sanniang, Xiu'e, Xue'er, you all take them to eat, these things won't taste good overnight!" ”

Li Kang took the lead in picking up a piece of roasted duck breast and ate it, and Sanniang and the others were no longer polite, and each picked their favorite food.

In fact, Li Kang and his son did not treat Sanniang and them as people, but treated them as family members, so even Xue'er has changed, and they all feel that when they meet a master like Li Kang and his son, it is really a blessing from the previous life.

Soon, the food brought back by Li Xiang was eaten by the four of them.

Li Kang couldn't help but praise: "It's really worthy of the imperial meal, it's so delicious!" ”

Xue'er also smashed the cherry and said, "Young Master, you are so good to us!" Cher feels so happy! ”

Li Xiang smiled slightly: "It's good to know!" I treat you as family, so don't be too restrained, just like your own family! ”

After speaking, Li Xiang smiled at Li Kang and said, "Father, shouldn't you give Sanniang a salary increase?" ”

Li Kang didn't think about it, so he said: "Yes, this is how it should be!" From this month, the price will increase by 300 yuan per person, what do you think? ”

Li Xiang nodded and said, "Okay, Sanniang, they are also very hard, they should send more money." ”

At this time, Sanniang, Xiu'e, and Xue'er were all moved to the red, and Sanniang said in a trembling voice: "Master, young master, you are really good to us subordinates, Sanniang has no ability, but she will definitely serve the master and the young master well!" ”

Li Kang hurriedly said: "Sanniang's words are serious! Xiang'er is right, don't treat yourself as a person, and I didn't treat you as a person, so do it well! ”

Sanniang nodded tearfully, since she arrived at the Li Mansion, this day has indeed been much better than before, not only has she had no worries about food and clothing, but she also has five hundred wen money to get every month, and now it has risen to eight hundred, such a good thing, you can't find it with a lantern!

Li Xiang had a dream, he dreamed that he married a beautiful little princess, and he was also a high school champion, and the two most proud things in his life made him come true, that is, the candle night in the cave room, and the title of the gold list. However, after his sweet dream entered the cave room, he woke up, which is the so-called spring dream without a trace!

After waking up, Li Xiang also felt that he was thinking too much? The princess's golden branches and jade leaves, will she like herself? Besides, I don't want to be a colt, I say that dreams are the reaction of people's subconscious, could it be that in my subconscious, I also want to marry the princess as Qin Jin's good?

No, it's useless to think so much, it's better to go with the flow! Li Xiang shook his head and got up. Today, he didn't want to go to Guozijian to take classes, but wanted to follow his father to see the progress of the promotion of biogas digesters and biogas lamps.

After breakfast, Li Xiang said to his father: "Father, how is the progress of the gas tank and the biogas lamp now?" ”

Li Kang smiled slightly: "What, do you want to go and see?" It's okay, today my father is going to the palace to inspect the construction of those large biogas digesters, let's go together! ”

Li Xiang nodded and said, "Okay, father!" Speaking of this biogas digester, although it looks simple, there are many exquisite things in it! If it is not repaired well, the gas production efficiency will be greatly reduced! ”

Li Kang said with a smile: "This father also knows that there are some on the drawings you designed, such as trying to choose a place with a good foundation, low groundwater level and leeward and sunny to build a pond. The biogas digester should be connected to the pig pen and toilet to facilitate the flow of manure into the pond and so on. ”

The father and son got into the carriage and came to the palace after layers of checking, and said that they had just come yesterday and were here now, but the day before was to make fireworks for the princess, and this time they came to see the construction of the biogas digester.

Father and son went to the site of a large biogas digester near the Imperial Dining Room, where a huge pit had been dug and the base had been tamped with a mixture of sand, lime and glutinous rice juice, and the walls of the pond were now being built.

To say that in this ancient times, although there is no cement concrete, but the wisdom of the ancients can not be underestimated, just say that this Sanhe soil, its durability is even better than cement concrete, but it is too glutinous rice, to carry out large-scale construction, the cost is high.

The origin of Sanhe soil, it is said that the earliest can be traced back to the Wei, Jin, Southern and Northern Dynasties period, often used in mausoleums, fortresses, its appearance, make up for the lack of lime in waterproofing, but also enhance the toughness of building gel materials. Of course, the biggest use is to build tombs, walls, arch bridges, and so on.

This biogas digester near the imperial dining room is a large biogas digester with a volume of 100 cubic meters, and its fermentation tank has a diameter of 10 meters and a depth of 4 meters, according to calculations, it can produce more than 20 cubic meters of biogas per day, which can be used for hundreds of people's lives.

Of course, there is more than one large biogas digester built in this palace, after all, there are tens of thousands of people in the palace, so just a few biogas digesters are not enough to deal with the waste that these people discharge every day.

Li Xiang followed his father to the front of the big pit, and couldn't help but sigh that there was no construction equipment such as excavators in ancient times, and such a big pit was completely dug by hand, and the efficiency was indeed lower!
