Luo Yong has been teaching Du Dalang to draw every day in addition to making soap.

To be honest, Luo Yong's own artistic level is not very good. The only skill is mostly made by practicing for the peony cushion in the past days. In the past, there was no problem teaching his own disciples. Now that he encountered a Du Gou like this, he often felt very stretched.

Fortunately, there are several art textbooks in his space. Luo Yong secretly looked at it a few times when he was fine, but he could barely deal with it.

But sometimes when he was really annoyed by Du Gou's question, he wanted to throw the books in the space directly over to him.                                                                                                               �

Of course this is not OK.

Du Gou is also quite interesting. While studying, he is eager to grasp the degree well, and he can always brake before Luo Sanlang gets furious.

According to Du Gou's own wish, of course he hoped to be in front of Luo Sanlang all day long and asked him to guide him to paint. However, Na Luo Sanlang seemed to have no interest in painting, and would rather stay in the backyard of Luo's family to make soap every day.

Early this morning, Du Gou got up early in the morning and suddenly thought of a question. After thinking about it, he couldn't figure out the answer. So he went to find Luo Yong again.

When he arrived at the Luo family yard, Na Luo Siniang said that his brother had gone to the sheep's house, so Du Gou went there too.

Luo used this early morning to see the growth of the alfalfa. Most of the seeds sown earlier had already sprouted and grew tender and thin grass leaves.

Luo Yong checked the soil moisture and felt it was still good. He should not need to water it for the time being. If there was another rain in the past two days, it would be even better.

In the wasteland not far from him, his disciples also got up to work at this time. They cut down the bushes growing on the wasteland and surrounded the alfalfa fields as fences to prevent these young seedlings from being eaten by goats.

When Du Gou passed by, he saw Xu Dalang digging the roots with a hoe, so he walked over and said to him: "It's too hard to dig like this, why don't you cut the bark?"

"What's the point of cutting the bark?" Xu Dalang raised his hand and wiped the hot sweat from his forehead, and said in discomfort.

"You just need to cut around the trunk twice and peel off the bark in the middle. The tree will wither and fallen leaves soon. As long as there are no leaves covering the sun, it will not hinder the farming. After two or three years, the tree will almost decay. Then you pull out the rotten trees." Du Gou explained to him.

Luo Yong happened to walk here at this time. After hearing this, he couldn't help but remember what he had learned in books before. Regarding the structure of the tree trunk, the tissue called phloem in the bark is a tissue called phloem in the bark.

Although Du Gou didn't know any phloem and xylem, he knew that using this method of peeling the bark, he could effectively dry up a tree or even die.

This is probably the wisdom of the ancients. With such wisdom, humans can open up their own civilization on this originally wild planet.

However, for those trees, this is simply a death talisman. Humans do not even need to spend their efforts to cut down those thick trunks. They just need to gently peel off a circle of bark from each tree, and they can easily kill a whole forest and turn the original forest land into arable land.

"Master?" Xu Dalang was not sure whether he should listen to Du Gou's words. When he saw Luo Yong coming over, he asked for his advice.

"Du Dalang's words are reasonable." Luo Sanlang thought that eating meat is really bloody and sinful, and he silently swallowed the fat piece of meat in his mouth. This is the field given to him by the emperor. He wanted to use them to farm and breed them, so how could he let the miscellaneous trees grow?

As a time traveler who is already more environmentally friendly, Luo Yong cannot give up his own interests for these trees, let alone other people in this seventh century.

It is probably because of this that the lush plateau in front of us will eventually become the Loess Plateau in later generations.

Thousands of miles away, in Chang'an City.

Li Shimin was inspecting his royal manor at this time. Throughout history, royal manors have been mostly run by relatives or other royal confidants, and often do not pursue economic benefits.

However, this emperor is really smart. Although he does not have the name of indiscriminate killing, he is also a decisive person. When doing things under such a king, everyone naturally has to be motivated and dare not act randomly. The economic benefits of this royal manor are actually very good now.

"...This piece of gourd grows well." The saints today praised all the way and were very satisfied with what they saw today.

At this time, they were walking through a vegetable garden. There were all kinds of vegetables growing in the garden. There was a piece of gourd planted here, a piece of loofah next to it, a piece of courgette in front and a piece of winter melon behind. At this time, there were about a few varieties of melon and vegetables.

The ancients mentioned that the melons and vegetables were basically these kinds of melons. Old pumpkins that tasted sweet, soft and glutinous, and were more filling were still growing on the American continent at this time, but did not in the Tang Dynasty.

His Majesty the Emperor had never eaten old pumpkin, so he had no regrets at this moment. He was very happy to see that these dealers in his manor were obviously growing stronger than in previous years.

"The method of burning soil manure is really useful," said the young official who was responsible for running the royal manor: "Your Majesty also knows that the manure supply in this manor is quantitative every year. If the same amount of fertilizer is used, the effect of fertilizing the land is obviously better than before."

"That's true." The saint nodded.

The next day, the saint discussed state affairs with several ministers, and talked about his experiences at the Royal Manor that day.

When the emperor treats his ministers, he cannot be serious and serious every time he meets. He occasionally has to chat with them about family matters and contact them.

These ministers basically have their own fiefs and manors. When it comes to the matters in this manor, everyone has a common language, and they say it very lively.

It’s not okay if it’s not lively. If the emperor wants to chat with them, can they still not give face?

"Na Luo Sanlang is really a wonderful person. Why don't I announce him to the capital and meet him with all my beloved ministers? What do you think?" said the emperor.

"Hahaha, the old minister also wanted to see Na Luo Sanlang, and I heard that he was a handsome young man." Someone among the ministers immediately supported him.

"I heard it was a coffin board." Someone joked again.

"If we know him, we can tell whether he is a handsome young man or a coffin board." The saint said with a smile.

After saying a few words from these people, Luo Yong would have to travel thousands of miles to Chang'an City, but he didn't know at this time.

In the early spring, Luo Yong planted a few loofahs next to his pigpen, and the vines of the loofahs climbed and grew along his pigpen.

Early this morning, Luo Yong stood on the slope in front of his yard and saw two small loofahs growing on the straw shed on the top of the pigpen below. He hadn't eaten loofahs this year, so he couldn't help but feel a little greedy, so he took a ladder and climbed up and picked the two loofahs off.

Just this day, Goro was resting at home because of the school holiday. When Si Niang was cooking at noon, he helped Si Niang and peeling the loofah fell into his hands.

In this era when there were no pedicures, using kitchen knives or small knives to peel loofah skins was quite a test of craftsmanship, and Goro's craftsmanship was not very good.

"How can the skin be so thick? You'll almost cut out the two loofahs." Si Niang couldn't help but complain when she saw the loofah he cut out. This year, their family was the first time to eat loofahs. Only these two were not enough for one or two people to eat.

"..." Goro grabbed his ears, looking ashamed.

"This loofah skin is really hard to peel." Luo Yong was moving a basket of soap out of the backyard. Seeing this scene, he spoke out for Goro to relieve the situation.

"Hmph, you will know you are spoiled by him." Si Niang hummed. In fact, this is Er Niang's catchphrase. Every time Luo Yong protects Si Niang, she would take out this sentence and chant it. Now Si Niang is used.

"I'm not very good at using a knife." Goro ran over to help Luo Yong carry the basket of soap.

"It's nothing, isn't it just a loofah? I'll make you a planer in the future." Luo Yong said with a smile.

"Isn't that planer used to plan wood? Can you still graze loofah?" Si Niang listened on the side, her face disbelief.

"What a scooter?" Du Gou was originally planning to go to the Xu family's guesthouse to have some fried noodles. When he passed by the Luo family's yard, he heard them talking about the scooter scooter. He was curious and turned around recently.

After Luo Yong told him about his "thinking" about the paring knife, Du Gou immediately became interested and stopped eating the fried noodles. He rode his horse and went to the city. It is said that he was going to go to the Iron Sword Shop to make a blade.

"Brother, he really went!" Wulang ran outside the yard and stood on the small earthen mountain next to his house. He watched Du Dalang ride away on a horse. Then he returned to the yard with a look of excitement and reported to Luo Yong.

"Just just to peel a loofah skin?" Si Niang said that the people in the city were too unreliable.

"What do you know?" Luo Yong said with a smile.

What is Du Gou's vision? What is his vision? What are his visions?

In the past few days, Du Gou also talked to Luo Yong about his experiences in Laizhou. It turned out that in Laizhou, every spring is the season for the abundant production of needle beam fish. This kind of fish is very ferocious. If you can't catch them with a fish net, you can use a fish hook to fish, and they will spit the hook again, which is quite troublesome.

It is precisely because it is difficult to catch and has a fierce temperament that there are many such fish in Laizhou area, especially in May and June every year, fishermen cannot catch stitches, nor can they catch other fish species. The flood of one species will inevitably invade the living space of other species.

In response to this situation, Du Gou came up with a method to fish with a barbed fish.

They found a lot of dried gourds, put the hook on the bait, tied it to the dried gourds, and sprinkled the string of gourds on the sea, and when they were taken back, they could catch a lot of needle-beam fish.

"This method is very good!" Luo Yong praised. Although he didn't know if this barbed fish hook was invented by Du Gou himself, he implemented this method locally, which would be considered a benefit to the people.

"Not necessarily." Du Gou shook his head and said, "The fish hook with barbs cannot be spit out after eating it. If the fishermen don't even penetrate the hook into their hands, it will be difficult for them to take out."

Luo Yong almost dared not imagine the scene of the barbed fish hook being pricked into the flesh.
