Li forgets to worry about a kind of top-grade tea produced in Qinling mountains that he drank in his previous life.

Yaowang tea!

This magical tea in the depths of the Qinling Mountains is only wild, and man-made can't survive.

It is said that the medicine king tea was discovered by Sun Simiao, the medicine king of the Tang Dynasty, during his latent cultivation in Taibai Mountain, Qinling Mountains.

It is said that when he lived in seclusion in Taibai Mountain, he often picked a leaf called tea lady to make tea. He also introduced it to mountain people and grass doctors. Later generations called it Yaowang tea.

Taibai materia medica records that Yaowang tea is mild in nature and sweet in taste, and enters the heart, liver and spleen meridians. Clearing summer heat, benefiting brain and heart, strengthening stomach, removing dampness, brightening eyes and regulating menstruation.

Li Qieyou knows that although it is called Yaowang tea, it is not tea, but a plant called "Huaxi silver Chimonanthus".

Yaowang tea is still fragrant after seven bubbles. It is a rare top-grade tea.

Li forgets worry to think of here, the saliva almost flowed out. Drink tea, he really wants to drink tea, not Datang's damn tea!

After thinking about it, Li forgets worry and immediately runs out. He goes to the Niu brothers to help pick tea.

Deep in the mountains of Qinling Mountains, Li forgets to worry and is conceited that he doesn't have the ability to go in. However, the Niu brothers often go hunting in the Qinling Mountains. I want to ask them to help pick this kind of tea. There's no problem coming back.

If you can pick the medicine king tea, you and Su Changqing will have good tea to drink. Thinking of this, Li forgets worry and speeds up his pace.

As expected, the Niu brothers were at home. Hearing that Li forgetful wanted to ask them for help, they went to Taibai Mountain to pick the leaves of a plant. Without hesitation, they immediately nodded and agreed.

"Xiao Lang, don't worry. My eldest brother and I are going to go hunting in the mountain tomorrow. We can help you pick the leaves in Taibai Mountain by the way." Niu Wu patted his chest and agreed carelessly.

"Thank you for coming back. I'll invite you to dinner at home," Li forgot anxiously.

"Pig killing rice?" Niu Wu never forgets the pig killing rice he ate that day.

Niu Yong glared at his brother, but he couldn't think of it.

Li forgets to worry about a black thread. If you are invited to dinner, you have to kill a pig? The landlord has no surplus food!

He quickly explained: "pig killing rice is not often cooked, but it is also a delicacy made of pork."

Li forgot to worry and described the appearance of Yaowang tea again. He confirmed that the Niu brothers had written it down before leaving.

When the Niu brothers go hunting in Qinling Mountains, they usually go for about a week. Thinking that they can have tea in a week, Li forget worry is full of expectation.

The next day, Yang Zuo was sure to keep his word. Early in the morning, he asked people to come and give ten farm cattle to Li forget worry, which once again caused a sensation in Dingzhou village.

Li forgets worry very simply and directly handed over ten farm cattle to the old village leader. Including the previous, a total of 20 cattle were lent to the village for spring ploughing free of charge. Only the village sent someone to help him manage the saline alkali land.

Now all the people in the village know through the publicity of the old village leader. At the request of Su Changqing, Li forgets to worry about using the drawings of the waterwheel in exchange for halving the rent adjustment in the village this year.

In addition, the farm cattle lent to the village for free, as well as Li forgetful's unforgettable pig killing rice... In short, Li forgetful's prestige in the village is even better than that of the old village.

If the old village hadn't stopped him, it is estimated that many villagers would have come to kowtow to Li forgetful sorrow.

Li Qieyou and Su Changqing are now walking in the village. Villagers will greet them warmly at any time. From time to time, villagers will send fresh mountain and river food to their families to show their gratitude.

The cattle brothers went hunting in the mountains, and Li forgot to worry. He also went to the Gan River and began to guide the farmers who helped him dig canals to drain water.

After being soaked in the river for two days, dig canals to discharge water. After the water in the saline alkali land is drained, plug the gap again and discharge water to soak again. This operation needs to be repeated three or four times to wash out the alkali contained in the soil.

It's rare for Li Qieyou to stand on the riverbank and watch everyone work. A river boat came slowly from the lower reaches of the Gan River.

Because Chang'an city is in the lower reaches of Gan River, general river ships go to Chang'an dongweiqiao wharf. In addition to fishing boats, there are few river ships carrying goods on the Gan River.

Li Qieyou looked curiously, but saw a man standing in the bow waving at him. As soon as he saw the figure, Li forgets worry and knows that Qiu Kun's fat man is back.

"Brother Qiu, how can I come by boat?" Li forgetful asked curiously. It took only an hour to ride to Dingzhou village from Chang'an City, but it took two days by boat.

"Ha ha, Xiao Lang, I really appreciate your news this time. My adult asked me to bring you another 100 stones of grain. As a thank you, please accept it." Qiu Kun shouted from the bow of the boat.

One hundred stone grain? This is a surprise.

Li forgets worry. Now the more food, the better. Of course, he will not refuse. Looking at the river boat landing with a smile, I thought that Qiu Kun would not charge him for his meal this time.

Well, I'm really a good man. I'm so generous!

Li Lianyou shamelessly praised himself in his heart. If Qiu Kun could hear his heart, I don't know if he would have the impulse to kill him.

Li forgets to worry is still praising himself, but hears the fat man utter a light cry: "Xiao Lang, what are these things that can rotate by themselves?"

"The waterwheel is used to carry water for irrigation." Li forgot to worry and explained.

Qiu Kun didn't care to talk to Li forget you. After jumping ashore, he ran to the waterwheel and looked up and down carefully.

"This waterwheel is amazing! It uses the water flow to push and automatically rotate to carry water! Xiao Lang, I'm afraid you didn't create it?" Qiu Kun, a fat man, saw the key to the rotation of the waterwheel at once, which surprised Li forget worry.

Li forgot to worry and nodded: "brother Qiu has good eyesight."

"Ha ha, in fact, my family also has farming. I wonder if brother Qiu can teach my enemy this waterwheel? Don't worry, I'll exchange food with you!" Qiu kunpang blinked a few times on his face and immediately put forward his request.

"Do you want a waterwheel? What do you say? I'll give you the waterwheel drawing later." Bai Bai took 400 stone grain from his enemy. Li forgets to worry. It's not good to collect money again.

If Yang Zui knew that Li forgot you had sent the waterwheel drawings to his enemies for nothing, he might have a heart to kill him with a knife. He was blackmailed by Li forgot you for the drawings in exchange for ten cattle.

After some conversation, Li forgot his worries and realized that the enemy was not only a big grain merchant in Chang'an, but also a big landlord.

Their family owns a lot of land in Hebei Road and Jiannan Road, and Zhuangzi is built to grow grain. Both the North China Plain and the Sichuan Plain are the main grain producing areas of the Tang Dynasty. Li Qieyou didn't expect his enemies to be so large.

With so much land, the water consumption is naturally huge.

Qiu Kun saw the value of the waterwheel at a glance, so he proposed to buy the manufacturing method of the waterwheel from Li forget you. If the enemy's villages are equipped with waterwheel, Qiu Kun estimates that the grain output can be increased by at least 10%.

Qiu Kun was overjoyed to see that Li forgetful was willing to give away the waterwheel drawings, and thanked Li forgetful again and again for his generosity.

He asked someone to help him transport the grain home. So much grain made the old housekeeper Li Heng's face full of smiles and began to wonder whether he should build another granary at home.

Invite Qiu Kun to take a seat in the main room. Li forgets to ask Qiu Kun how his family is going to deal with the coming locust plague.
