Wang Junkuo escaped by killing people, and the entire Chang'an City was under martial law, but just like the old enemy said, people may have escaped from Chang'an City, so it is useless to check, but it is impossible not to check, but it turns out that it brings great trouble to the people in the city, and it is very inconvenient to enter and exit the city gate. Pen, fun, pavilion www. biquge。 info

However, when he was on the road, Li Xiu had been thinking about Wang Junkuo in his mind, this person's fate was also affected by him, if he remembered well, Wang Junkuo seemed to be called back to Chang'an, he ran away with a weak heart, and was killed by the wild people in the countryside, but now he was escorted back to Chang'an, but he escaped again, but I don't know if he can change the fate in history?

I don't know how long it took, when Li Xiu woke up from his contemplation, he opened the window of the car and looked around, and found that he was about to arrive home, and a little further forward was the official office of the Ministry of Agriculture, which suddenly thought of something, so he ordered the coachman to stop the carriage, jumped out of the carriage and asked them to go back first, and then walked towards the official office of the Ministry of Agriculture.

The bazaar in front of the official office is becoming more and more formal, the number of shacks is not only more, but also the style is neater, all kinds of small traders shouting their own business to attract guests, Li Xiu walked through the crowd to the familiar Hu cake stall, the uncle who sold Hu Biscuits saw him, immediately picked a golden Hu Biscuit and cut it, and then stuffed two taels of cut mutton, Li Xiu paid with a smile, took the Hu Biscuit and ate while walking, although he had just eaten a banquet in Wufu, but in that case, the main thing was to chat not to eat and drink, In fact, he was already hungry on the road.

Li Xiu took the Hu Cake and walked into the official office of the Ministry of Agriculture while eating, and the officials inside nodded and greeted him when they saw him, although the Yamen was not allowed to eat casually after Ying Mao, but everyone was selectively blind to the Hu Cake in Li Xiu's hand, after all, Li Xiu was originally a special existence in the Ministry of Agriculture, and it was normal to not see anyone for a few days.

After entering the yamen, Li Xiu wanted to go to the backyard to find Yang Dui, but he didn't expect to meet Yang Nong, and when the other party saw him, he was very happy to stop him and said: "Li Xianjiu, you came just in time, I happen to have something to look for you!" ”

"Oh? What makes Yang Shangshu so happy? Li Xiu couldn't help but ask in surprise when he heard this.

"Hehe, don't call me Shangshu anymore, I have taken the initiative to give up the position of Hubu Shangshu two days ago, so now I am just Langzhong of the Ministry of Agriculture, you still call me Yang Langzhong!" Yang Nong heard Li Xiu's words but corrected with a smile, he didn't care about the affairs of the household department for a long time, and it just so happened that Li Shimin also wanted to install people in the household department, so he simply took the initiative to retreat, which can be regarded as selling Li Shimin's favor.

"It's good to hand over the position of Shangshu, so as not to be implicated in the court battle again, such as Pei Xiang and Wu Shangshu of the Ministry of Industry, the current life is not very good, Yang Shangshu, since you have retired, you can also manage the affairs of the Ministry of Agriculture with peace of mind, and it is indeed a little inappropriate to call Shangshu again, I will call you Yang Gong in the future!" Li Xiu was stunned for a moment when he heard this, and then smiled again and said.

"Haha~, whatever you want, it doesn't matter what it's called!" Yang Nong also laughed when he heard Li Xiu's honorific title, then paused and then said, "But I didn't stop you to talk about it, the person you asked me to find last time has been found, I just don't know when you will have time to visit with me?" ”

"Huh? Have you found it already? Li Xiu couldn't help but be surprised when he heard Yang Nong's words, he had only gone to find Wu Shi Tong today, hoping that he would help him find a craftsman who knew how to build ships, but he didn't expect Yang Nong to find it so coincidentally, if he knew so, he might as well not go today.

"Yes, I sent someone to inquire around a few days ago, and finally found a person's residence, but this person's identity is a little special, and the shelf is a little big, so it's better for us to visit in person, I don't know what you think?" At the end, Yang Nong asked again.

"No problem, I'm available at any time, but I don't know when Yang Gong will be free?" Li Xiu was also very excited when he heard this, although he had already asked Wu Shi Tong, it was nothing to meet the person recommended by Yang Nong first, and it was nothing to invite the two of them to teach Qi Niang together.

"That person lives in Chang'an City, it just so happens that I have to go home tomorrow, when you come to me, let's go to Chang'an together!" Yang Nong immediately spoke.

"Okay, that's it!" Li Xiu immediately agreed, and then chatted with Yang Nong about the things in the yamen, and then said goodbye and left, as long as he invited people tomorrow, he didn't have to worry about Qi Niang's daily thoughts.

At that moment, Li Xiu stepped into the backyard of the Yamen, which is actually the experimental field of the Ministry of Agriculture, with greenhouses and ponds, and various crops grow on the fields opened up, Yang Dui has become the third person in the Ministry of Agriculture, but he is still very hard-working, and he usually soaks here as long as he is free, and is familiar with the habits of various crops.

Li Xiu saw Yang Dui standing next to a sweet potato field at a glance, and walked over at the moment, but Yang Dui also saw him at this time, and immediately greeted him with a smile and said, "Why are you here, Li Xijiu?" ”

"I just came back from Chang'an City, and I came to see it when I passed by, by the way, how did you do last time?" Li Xiu asked with a smile.

"It's such a coincidence that you're here, and I'm about to talk to you about it!" I saw that Yang Dui was also quite excited at this time, "Last time you said that there are good rice seeds in Zhancheng, so I sent an official letter to several state capitals in the south in the name of our Ministry of Agriculture, hoping that they can go to Zhancheng to get some rice seeds back, and now the south has replied, saying that someone has been sent, and it is estimated that it will not be long before there will be news!" ”

"That's good, you pay more attention to this matter, although the yield of Zhancheng rice is not as good as corn and sweet potatoes, but it is very suitable for planting in the south, it is said that it can be harvested three times a year, if you find it, you can promote it in the south!" Li Xiu also nodded when he heard this, corn is not suitable for planting in the south, although sweet potatoes are good, but the nutritional structure is single, and rice and noodles still have to be eaten, so he thought of Zhancheng rice, this thing seems to have been introduced in the Song Dynasty, and now it can be hundreds of years in advance.

"Li Saijiu, don't worry, the matter of Zhancheng rice is wrapped up in his subordinates!" When Yang Dui heard this, he immediately patted his chest and assured, unlike sweet potatoes and corn, Zhancheng rice was a task given to him by Li Xiu in private, and if he did it well, nearly half of the credit would be his, so he was also full of motivation.

Hearing Yang Dui's assurance, Li Xiu also smiled, he was also very optimistic about this very motivated subordinate, but Yang Nong said that his nephew was not from a formal background, and his future career was limited, which made Li Xiu feel sorry for Yang Dui.

After chatting about Zhancheng Dao, Li Xiu had nothing else to do, and was about to leave at the moment, but at this moment, I saw Yang Dui suddenly grab his arm, and said very excitedly: "Li Xianjiu, there is one more thing I want you to see!" ”

"Oh? What's up? Li Xiu was also a little surprised when he heard this, mainly because Yang Dui's expression was too excited, which made people feel a little abnormal?

"Hehe, just check it out!" Yang Dui deliberately sold it and didn't say anything, which made Li Xiu even more curious, and nodded immediately, "Okay, where is it?" ”

"Not in the yamen, but outside the yamen, I'll take you now!" Yang Dui spoke excitedly again, turned around and took Li Xiu out of the yamen.

At that moment, Li Xiu followed Yang Dui out of the yamen, crossed the bazaar and turned south, walked for nearly a mile, and then came to a fenced open space, and a simple small shed was built in the middle, which made Li Xiu also a little surprised, because this place is not very far from his house, standing here can even see his house, but he doesn't know when a small shed was built here that he doesn't know the purpose, could it be said that this is a toilet?

I saw Yang Dui push open the fence door and walk in, and then smiled at Li Xiu: "Do you know what Li Xijiu does here?" ”

"This ......" Although Li Xiu wanted to say that this might be a toilet, after all, it was too low, but seeing Yang Dui's serious appearance, he was really embarrassed to say it, so he could only shake his head in the end.

Seeing Li Xiu shaking his head, Yang Dui was even more excited, and immediately pulled Li Xiu to the small shed, only to see that this shed was a little strange, there was nothing empty inside, but there was a thin bamboo tube sticking out on the ground, and the mouth of the cylinder was wrapped in a circle of iron, and a ball of rags was stuffed on it, and I don't know what it was for?

"Li Saijiu, do you remember what you taught me at the beginning?" Yang Dui asked even more excitedly at this time.

"What was taught to you?" Li Xiu couldn't help but smile bitterly when he heard this, because when he got along with Yang Dui before, sometimes he deliberately told Yang Dui some knowledge of the later generations, and sometimes he was full of nonsense, so for a while, he didn't know what Yang Dui was talking about?

"This is it!" Yang Dui said and suddenly took out a fire fold from his arms, and after igniting it, he reached out and took off the rags on the bamboo tube, and brought the fire fold over, only to hear a slight popping sound, and a yellow and red flame came out of the bamboo tube, which was by no means the bamboo tube burning, but the gas coming out of the bamboo tube was burning.

"This ...... It's natural...... No, it's biogas! Li Xiu saw this familiar scene, and couldn't help but be very excited at the moment, when he was cooking at home in his previous life, he had seen too many similar scenes, but there was absolutely no natural gas in this era, the only possibility was that Yang Dui got the biogas out, and he suddenly remembered that he seemed to have mentioned something about biogas to Yang Dui before, but he didn't expect him to really get it.

"That's right, it's biogas, when I heard about biogas from the sacrificial wine, I was very interested, so I asked people to build a biogas digester here, this pipe goes straight to the ground, and a lot of dirty things are thrown into the biogas digester below, but I didn't expect that it can really produce biogas that can be burned." Yang Dui was very excited and said, this was an experiment he made independently, and it was successful, which made him feel a sense of accomplishment, so he couldn't wait to show it to Li Xiu.

"Hahaha~, yes, yes, Yang Dui, you are really amazing, you actually got it out just by listening to me say a little bit of biogas!" Li Xiu couldn't help patting Yang Dui's shoulder and exclaimed, biogas is also closely related to agriculture, and many rural families in later generations used biogas as fuel, and there were also biogas digesters at home, so Li Xiu told Yang Dui about some, but he didn't expect him to really care.

Hearing Li Xiu's praise, Yang Dui was even more happy, and immediately pulled Li Xiu to tell him about his biogas, but Li Xiu saw that the bamboo tube was still burning, and immediately reminded: "Let's put this out first, so as not to cause a fire......

Before Li Xiu's words fell, he saw Yang Dui directly stuff the rags in his hand back onto the bamboo tube, which scared Li Xiu into a cold sweat, because this practice is too dangerous, you must know that there is a biogas tank below, in case the flames detonate the biogas tank below, I am afraid that they will both die without a body.

But fortunately, after Yang Dui blocked the bamboo tube with rags, the flames were immediately extinguished, and there was no movement in the underground biogas tank, which made Li Xiu wipe the cold sweat on his forehead, thinking that Yang Dui was really stupid and bold, and blamed him for not telling how dangerous the biogas was.

Yang Dui was in a hurry to show off his achievements to Li Xiu, but he didn't pay attention to Li Xiu's abnormality at all, and immediately ran outside to introduce the biogas digester to Li Xiu. Seeing him so happy, Li Xiu was embarrassed to interrupt, thinking in his heart that after leaving here for a while, it would not be too late to tell Yang Dui about the safety measures that he needed to pay attention to.

"Li Saijiu, look, this is the feeding port of the biogas digester!" I saw Yang Dui run to a corner of the open space outside the small shed, and reached out to lift up a stone cover, revealing a black hole.

Li Xiu also came over to take a look at it at this time, and found that the entrance of the cave was quite deep, and it was built with green bricks next to it, which looked more like a deep well, but there was a foul smell from the hole, which was also normal, after all, it was all some people's urine feces or rotten vegetable leaves, and the taste was definitely not good.

Li Xiu pinched his nose and looked carefully into the hole, then immediately took a few steps back, then took a long breath of fresh air, and asked casually: "Yes, how much is the range of this biogas digester and what is the depth?" ”

"The range is not very large, the position we stand in is to the small shed, but about seven or eight steps, as for the depth......" When it came to the depth, Yang Dui seemed to be a little unable to remember for a while, so he looked into the hole by himself, and the result was that the black hole couldn't be seen clearly at all.

Originally, Li Xiu just asked casually, and it was nothing if Yang Du couldn't answer, but he might be in a hurry to show that he had to figure out how deep the biogas digester was? So he made a move that frightened Li Xiu, and took out the fire fold in his arms again and ignited it, apparently wanting to take a look at the depth of the cave...... (To be continued.) )
