"This is impossible. The wheat yield per mu is only 100 or 200 kilograms, and the best fields are only 200 kilograms. Although the rice yield is a little higher, even the most fertile paddy fields, the best rice seeds are only 300 kilograms. As for the yield per mu, even the gods may not be able to do it!" Li Yuan shook his head when he heard Li Chengdao's words. He did not believe that there is a grain yield per mu in this world.

"Really, I won't lie to you, the yield of that kind of sweet potato is really high!" Seeing that my grandfather didn't believe it, Li Chengdao said anxiously at this time. At a young age, he was very simple, just wanted his grandfather to pay attention to sweet potatoes and benefit the people of the world as soon as possible.

"Okay, maybe this crop called sweet potato does have higher yields. If I have time in the future, I will send someone to confirm it to Li Xiu." Seeing Li Chengdao's anxious look, Li Yuan said with a smile. However, he didn't believe in the world that produces more than a thousand kilograms per mu. Otherwise, he, the emperor, would not have known it. There is a certain reason for this. Unfortunately, Li Yuan did not know that these crops came from the distant America.

"But..." Li Chengdao saw that his grandfather was just perfunctory to him, trying to argue again but didn't know what to say. In the end, he just lowered his head a little depressedly. He knew that his grandfather was a very stubborn person and wanted to convince him that he would be useless unless he got tangible evidence.

"Okay, Chengdao, you're tired of going out for a day. Your father must be worried about you too, so you'd better go back. I have something to talk about with Pei Jian!" At this time, Li Yuan said again. He didn't want to argue with a child that was so unbelievable. In his opinion, either Li Chengdao heard it wrong or Li Xiu was coaxing the child to play, but Li Chengdao actually believed it.

Li Chengdao did not dare to disobey his grandfather's orders, so he had to turn around and leave silently, but his little face was still a little unwilling and even a little aggrieved. When he came, he was extremely excited and thought he could rely on sweet potatoes to save Wan Min, but he didn't expect that his grandfather didn't believe his words at all.

Seeing his grandson leaving with a grievance, Li Yuan smiled and shook his head. The child had a good personality, but he was a little stubborn, but he looked very much like himself. Moreover, he was even more stubborn than Li Chengdao when he was young, and sometimes he was unwilling to listen to the opinions of his elders.

"Your Majesty, do you really have a grain yield of 1,000 kilograms per mu?" But at this moment, suddenly, Pei Ji, who had not spoken, said, and when Li Yuan turned his head, he saw the other party's face full of doubts.

"Haha~, Pei Jian, don't you really believe the words of children, right?" Li Yuan couldn't help laughing when he heard this.

"Your Majesty, Prince Anlu said just now that Li Xiu has cultivated a new vegetable, which is not only very large, but can also be preserved for a winter. Although we are surprised, we do not doubt that since Li Xiu has such ability, why can't he cultivate a grain with a yield of thousands of kilograms per mu?" Pei Ji asked back at the end. In contrast, he seemed to be more confident in Li Xiu, but he overestimated Li Xiu. Sweet potatoes are not as artificially created as cabbage.

"This..." Li Yuan also showed a deep expression after hearing this. He had contacted Li Xiu several times and collected a lot of information about Li Xiu from various aspects. However, his understanding of Li Xiu was still limited. It was wrong. It should be that Li Yuan thought he knew Li Xiu enough, but he could always do things that he unexpectedly could not have been done, which made him feel that Li Xiu was covered with a layer of fog that allowed him to see the truth clearly.

"But are there really crops with a yield of over 100 kilograms per mu in this world?" Li Yuan pondered for a long time, and finally asked in disbelief, even if he asked Pei Ji and himself.

"Why are your Majesty so entangled? I'm just free tomorrow. Why don't you go there on behalf of Your Majesty and see with your own eyes what the sweet potato is in Prince Anlu's mouth!" At this time, Pei Ji suddenly smiled. He had seen Li Xiu twice before, but he would feel different every time, especially after seeing Li Xiu pay tribute to Princess Pingyang, he was even more shocked.

"Okay, then Pei Jian, please come for me!" Li Yuan nodded in agreement after hearing this. Since becoming emperor, he could not go out as casually as before. This also made Pei Ji almost his eyes and ears. Only Pei Ji's words could make him fully believe that even Li Jiancheng and Li Shimin could not compare with Pei Ji.

The next morning, Pei Ji left Chang'an City and headed straight for Li Xiu's home. The spring was just right now, so Pei Ji rarely went out, so he opened the car window and enjoyed the spring scenery outside while walking. He saw that both sides of the road were covered with green wheat seedlings. Although it was very cold last winter, it also snowed a lot, which made the soil moisture in the fields very good, and no longer had to be irrigated. All the wheat grew very well. As the prime minister of this huge emperor, Pei Ji felt very fulfilled.

Seeing that he had arrived at the Li family village not far from Li Xiu's house, he passed a small river and walked a few hundred steps ahead, and it was Li Xiu's house. This also made Pei Ji start to think about what to say when he saw Li Xiu later? Although he told Li Yuan yesterday that he was here to inquire about the sweet potato for him, in fact, he was not so simple when he came to see Li Xiu.

"Huh?" But at this moment, when Pei Ji's eyes accidentally swept across a field by the river, he was surprised to find that there was a crop growing in the field that he didn't know at all. What's even more surprising is that most of the wheat seedlings only grew as high as chopsticks, but this crop had grown beyond the knees. Against the backdrop of the surrounding wheat fields, it looked a little prominent and very conspicuous.

"Stop!" Pei Ji couldn't help but open his mouth when he saw this strange crop. Although he was not a farmer, he had suffered a lot when he was young. In addition, he had rich experience in most of his life and was very familiar with crops. However, he had never seen the crop in front of him. Moreover, he knew that it was either the fields of Li Xiu's family or the fields of the princess family, so he suspected that this was the legendary sweet potato.

With a little curiosity, Pei Ji jumped out of the carriage. Because he was afraid of trampling on the crops, he did not take his subordinates. He came along the ridges alone to the strange crops. He looked down and looked at them seriously. He saw that the roots and stems of this crop were thick, and the wheat seedlings beside him were incomparable. The leaves were wide and long, and they looked like sharp swords. And judging from the appearance of these crops, they seemed to grow taller.

"It looks a bit like sorghum, but since the name of sweet potato has the word "potato", it should be that the root below can be eaten. Does it mean that the root below has other secrets?" Pei Ji said to himself at this time that the word potato is a general term for all crops that can be eaten by underground rhizomes.

After Pei Ji finished speaking, hesitated for a moment and finally squatted down. He rolled up his sleeves and planned to dig out the soil below to see the rhizomes of this crop to verify his guess. Unfortunately, he didn't know that the crop in front of him was not sweet potatoes, but corn at all.

"Food thief, don't run away!" But as soon as Pei Jigang took action, he suddenly heard a silence from afar. Then an old farmer waved his hoe and rushed towards him. It seemed that he regarded it as a thief.

"I...I'm not..." Pei Ji instinctively wanted to explain, but when he saw the other party's angry momentum, he wanted to kill him with a hoe. This made him curse inwardly. These farmers value crops more than life. If you touch other people's crops, you deserve to be beaten to death, and even the government will be sentenced lightly.

"Run!" Pei Ji knew that nothing was useful at this time, not to mention that he really wanted to dig other people's crops, and the soil in his hands was ironclad evidence. If a prime minister was beaten by an old farmer, it would be shameless to see people. So the best way now is to escape back to the carriage on the way.

Fortunately, the farmer waving the hoe was far away from Pei Ji, and he was afraid of trampling on the crops and didn't run fast, so Pei Ji easily ran back to his carriage and then shouted: "Get out of here quickly!"

Maybe it was because he saw Pei Ji getting into a luxurious carriage on the road, and the old farmer stopped to chase him. But even so, he still shouted and scolded him. The corn was highly valued by Li Xiu and Princess Pingyang. In fact, Li Xiu had told the people of Li Family Village that they should take care of these corn day and night and never suffer any harm. With Li Xiu and Princess Pingyang behind their backs, the people of Li Family Village were hardened. Even if you are a nobleman in Chang'an City, you can't think of it if you touch the corn.

Pei Ji, who was sitting in the carriage, smiled bitterly at this time. He didn't expect that his grand prime minister of the Tang Dynasty would be so embarrassed by an old farmer. Of course, with his mind, he would not care about anything with an old farmer in the countryside, otherwise it would only make people even more ridiculous.

The carriage passed the wooden bridge on the river and finally came outside the door of Li Xiu's house. Then he stepped forward and knocked on the door with his own hands. Then a strange maid opened the door, looked up and down and asked, "What's wrong with this guest?"

"May I ask your master is at home. I am Pei Ji, come and visit me!" Pei Ji said with a smile. He had been to Li Xiu's house last time, but it was not the maid who received it.

"Pei Ji? Ah, I remembered that you are the father of my wife?" The maid was stunned when she heard Pei Ji's name, and then said suddenly, but her memory was obviously problematic, and she confused Pei Ji and Pei Ju's names. After saying that, the maid said with a stern face, "I'm sorry, my master and wife are not here, so you'd better ask back!"

After the maid finished speaking, she closed the door with a "bang~", which made Pei Ji outside the door smile bitterly. It seemed that he didn't read the calendar today. He was first chased by an old man, and now he was trapped by the other party's confusing name and turned away. (To be continued.)
