Regarding Du Ruhui's physical condition, Li Xiu still suggested that Li Shimin find a doctor to check the other party. After all, Du Ruhui died this year in history, and was only forty-five when he died. For an official, forty-five is their golden age. Moreover, with Du Ruhui's current status, it would be a pity to die so early.

Li Shimin also attached great importance to Li Xiu's suggestions. He was worried that the imperial doctors in the palace would not work, so he immediately ordered someone to invite Sun Simiao to the palace, and then took the other party to check Du Ruhui himself.

Li Xiu did not join in the fun, but returned home and wrote a letter to Zhao Deyan. This time the Turks rebelled on the road, Zhao Deyan would definitely bear the main responsibility, but this was not too serious, and the court would not punish him too severely. In addition, there were some suggestions from Li Xiu for escorting the Turks. These would definitely be given to him by the court's official documents, but it would not prevent Li Xiu from giving him some ventilation in advance so that he could prepare to avoid making the same mistake again.

The next morning, Li Xiu had breakfast and played with his daughter Le'an for a while, and then went out of the house to the Ministry of Agriculture. After all, he was still in charge of the Ministry of Agriculture. Although he didn't take much care of the affairs, he had to come and go around, at least to show off, so as not to be impeached by some idle censors.

However, what Li Xiu did not expect was that he did not see Yang Dui in the Ministry of Agriculture, and even Shangguan Yi was not there, which made him a little strange. He pulled a small official and asked, and then he realized that Yang Dui had gone to the official fields beside Huangqu early this morning. These official fields were specially divided by Li Shimin for the Ministry of Agriculture, which was equivalent to the experimental fields in later generations.

Guantian was not far from the Ministry of Agriculture, so Li Xiu stepped to Guantian. When he came here, he saw Yang Dui and more than a dozen officials working in the Guantian. On the land under their feet, green seedlings were growing vigorously. Li Xiu also recognized these seedlings, which were the potatoes brought by the bearded guest from America.

Potatoes are a crop with a yield of no less than sweet potatoes. However, the bearded guest did not find it when he went to America for the first time. He brought the potatoes back until he returned from America for the second time. Moreover, the number was not large. Li Xiu planted them in his own garden. However, because of his lack of planting experience, few of these potatoes survived, and the yield in the first year was even less pitiful.

Faced with this situation, Li Xiu had to hand over the potatoes to professionals from the Ministry of Agriculture to grow, which made Yang Du and others very excited. The promotion of corn and sweet potatoes in some areas of the Tang Dynasty has increased the yield of the Tang Dynasty several times. Now there is another potato. I am afraid that the Tang Dynasty will be in too much food to eat in the future.

"Yangdu, have you cultivated so many potato seedlings?" Li Xiu strode to the field, then smiled and said, looking at the endless potato seedlings in the field with joy.

Yang Dui was discussing something with his officials, but he didn't notice Li Xiu. He then looked up when he heard his words, and then smiled and said, "Why are you here, your son-in-law? But how is the growth of this potato?"

"Not bad, I almost planted the potatoes to death in my hands. Now, in just a few years, you have cultivated the potatoes into such a large area. It seems that it will take a few years to promote the planting in other places!" Li Xiu couldn't help but nod and exclaimed when he looked at the potatoes around him.

"If it weren't for your keen eye, you wouldn't have the chance to plant such high-yield crops from America, as for the promotion of potatoes, there is no need to be too anxious. After all, corn and sweet potatoes are still being promoted. It's not too late to promote potatoes after they are promoted nationwide." Yang Dui said with a smile.

Hearing Yang Dui's words, Li Xiu nodded. With the promotion of corn and sweet potatoes, the current food pressure in the Tang Dynasty is indeed not high, so there is no need to worry about promoting potatoes. What's more, the storage of potatoes is also a problem. Although potatoes can be stored for a long time, they will sprout or even ** over time. Sweet potatoes can at least be dried into dried sweet potatoes, but what should I do? You can't dry them into dried potatoes, right?

However, Li Xiu was too lazy to care about these things. Anyway, with Yang Du and others, they would always think of a solution in the future. However, he did not forget to remind Yang Du that potatoes were poisonous after sprouting. Although they might not poison people to death, they tried not to eat them.

Just as Li Xiu and Yang Dui were talking about potatoes, he suddenly saw a carriage coming from the official road not far away. Li Xiu recognized it at a glance that it was the carriage in the palace, which made him a little strange. He couldn't figure out who left the palace?

"Prince Consort!" But at this moment, he suddenly heard someone calling Li Xiu in the carriage, which made him stunned. From this voice, he knew who the other party was.

The carriage soon came to Li Xiu, and the car window was opened. An old man with a young face was sitting and greeting him. It was Sun Simiao who was summoned to the palace by Li Shimin yesterday.

"Master Sun, why are you back?" Li Xiu walked up and asked Sun Simiao with a smile. Yesterday, the other party was summoned to the palace by Li Shimin, and then went to check Du Ruhui's health. He originally thought that the other party should have come back yesterday, but he didn't expect that he would come back today, which made Li Xiu have a bad premonition.

I saw Sun Simiao jumping out of the carriage, but his steps were a little sloppy, which made Li Xiu hurriedly come forward to support him. Only then did Li Xiu realize that Sun Simiao's eyes were red and his face was exhausted, as if he had been busy all night.

"Mr. Concubine, thanks to your current situation, otherwise Du Xiang would be in danger!" After Sun Simiao stood firm at this time, he also showed a fearful expression.

"What's going on? Is Du Xiang's health bad?" Li Xiu asked anxiously when he heard this.

"It's not just bad, it's extremely dangerous!" Sun Simiao waved his hand and asked the person who sent him in the palace to leave, and then pulled Li Xiu to the side and said, "Du Xiang's body is not very good. In recent years, it has been in a state of affairs day and night, which has hurt his spirit and energy and greatly damaged his body. Although he is only in his forties, his body is worse than that of an old man in his seventies or eighties. Fortunately, the prince-consort showed that Du Xiang's complexion was wrong, and finally I had some time to regulate his body. Otherwise, once these accumulated problems in his body were exposed, even the God of Daluo would not be able to save him!"

"How is Du Xiang's health now? Master Sun, are you sure to cure his illness?" Li Xiu couldn't help but ask nervously when he heard what Sun Simiao said.
