Two days later, in the palace, Zhao Yu looked at Wu Zheng who came to report it, and couldn't wait to smash the jade paperweight in his hand.

The yield of the upper, middle and lower fields has decreased by two and a half stones per mu, how can this not make him angry?

He took a deep breath and asked, "Besides Du Jinning's Zhuangzi, aren't there other places where this kind of high-yield rice is grown?" What's the situation there? ”

"It's pretty much the same." Wu Zheng said, "Those fields, the minister inspected them one by one some time ago, and they all had the same problem, the rice ears were not full. The day before yesterday, the Dujia Zhuangzi was harvested and found that the situation was wrong, and the minister asked people to harvest several other places yesterday, and it turned out that they were all the same yield. ”

Zhao Yu's face was even more ugly.

He calmed down for a while before asking, "What is the reason?" Did you find out? ”

Wu Zheng shook his head: "I have checked it, but I can't find it." In the past six months, the ministers would go to Runzhou once every ten days and half a month, and found that their method of planting rice was the same as originally said. Moreover, according to the minister's experience, even if this is a high-yield rice, the planting method should be no different from other rice, and there is nothing wrong with the farmers' approach. Chen really couldn't understand why the output was so different. ”

After a pause, he glanced up at Zhao Yu and said cautiously: "The minister has discussed it with the officials of the Ministry of Industry, and I think the problem may be in the seed. ”

"Seeds?" Zhao Yu's brows furrowed, "How could there be a problem with the seeds?" ”

Wu Zheng: "Some plants, seeds can be degraded. For example, if a tea tree with a particularly good taste is found in the mountain, and its seeds are used to cultivate tea seedlings, even if it is planted in the original environment in the original place, the tea planted will still be far from the taste of the mother plant. This should be degradation. ”

After a pause, he showed a stunned look on his face: "Later, I learned from Lord Du Jinning that you can survive by cutting off the tea branch and inserting it in the ground and taking care of it carefully." The tea seedlings grown in this way taste the same as the mother plant. ”

Therefore, the minister thought, Master Du must have some special way to keep the rice grown high yield. He was able to produce high-yielding rice seeds, and it was not difficult to maintain their characteristics. It's just that we can't get in, so we don't know what to do. Just like planting a tea tree, knowing it feels very simple; What I don't know is a big problem. ”

Zhao Yu was silent for a long time.

After a long time, he said to Wu Gonggong: "You go and call Qi Bokun too." ”

When Qi Bokun arrived, he asked Wu Zheng to repeat what he had just said, and asked Qi Bokun: "Aiqing, look, will Du Jinning write any notes and put them in her mansion in the capital or Runzhou?" ”

Qi Bokun's face changed slightly.

He coughed twice: "Although the minister loves Du Jinning as a nephew, they are two families after all. What habits she had, the minister didn't know. ”

As he spoke, he coughed a few more times, and coughed hoarsely, as if he were about to cough out his lungs.

Zhao Yu was about to go further, but he had to stop and asked with concern: "Aiqing is suffering from the cold?" Imperial Doctor Xuan came to show Aiqing? ”

When Qi Bokun was coughing, he took a few steps back and deliberately stayed away from Zhao Yu.

At this time, he said weakly: "Okay, thank you emperor." After a pause, he said, "The minister should go back, so as not to make the emperor sick." ”

Although Zhao Yu suspected that Qi Bokun was pretending to be sick, he couldn't, so he had to say: "Aiqing has been tired, since she is unwell, then she should rest at home for a few more days." ”

When Qi Bokun left with a slight slump, he looked at Wu Zheng and let out a long sigh: "Okay, you can go back." I will ask people to look for Du Jinning again. If you can't find her, you can plant another season on Dujia Zhuangzi next spring to see if the yield will continue to decrease. If the current output can be maintained, it can basically alleviate the grain problem in the Great Song Dynasty. ”

"Yes." Wu Zheng gave a salute and retreated.

Back at the Ministry of Industry, Nie Ruilin, the left attendant of the Ministry of Industry, asked with concern, "How is it?" ”

This Zuo waiter was also picked up by himself, and Wu Zheng did not hide it from him, and told him everything about the situation in the hall.

Nie Ruilin frowned and said, "Why do you have to find Du Jinning's notes with Lord Qi's consent, and if he doesn't agree, he can't search for them?" This kind of thing is beneficial to the country and the people, but how can it be done because of personal friendship? The emperor is too accommodating to Lord Qi, right? ”

Wu Zheng is old and in poor health, so he wanted to recommend Nie Ruilin to take over his class. Hearing this, he wondered if he had chosen the wrong person.

He said lightly: "It's not a matter of personal friendship. Du Jinning's contribution to the Great Song Dynasty is obvious to all, and everyone in the court knows about it. At this time, he disappeared for half a year, and the emperor asked someone to search his house, doesn't this make people feel chilling, and feel that the emperor is unkind? Such a master, are you willing to give everything you have to follow? Lord Qi spoke with the wind and cold, and also vaguely admonished the emperor not to do such a chilling thing. If the emperor insists on going his own way, Lord Qi is afraid that he will be killed due to illness. ”

Only then did Nie Ruilin realize that he was still very far from the two bosses.

He got up and saluted Wu Zheng sincerely: "Thank you, Lord for teaching." ”

……

Zhao Yu naturally knew that his proposal was inappropriate, and sent a doctor to treat Qi Bokun that day, and rewarded him with many precious medicinal materials.

After a few days, when Qi Bokun "recovered" and returned to the court, he deliberately left Qi Bokun behind, and after greeting his body, he sent away everyone except Gonggong Wu, and asked: "Aiqing, does you know that Du Jinning is a woman?" ”

"What?" Qi Bokun raised his head suddenly, his face changed suddenly, and even his voice was a little higher.

His astonishment was not a hypocrisy. He naturally knew that Du Jinning was a woman, but he didn't know that Zhao Yu also knew about it.

"This ...... How can it be? He asked.

Seeing Qi Bokun's expression, Zhao Yu was very satisfied.

If Qi Bokun knew that Du Jinning was a woman and hid it from him, he would have a feeling of betrayal, and he would definitely not trust Qi Bokun and Qi Muyuan in the future.

And now it seems that this courtier is still very loyal and did not deceive himself with Du Jinning.

He nodded, "It's true." Lu Guo said. ”

Qi Bokun suddenly realized.

Before Du Jinning disappeared, he had been to King Jing's Mansion, and it was at that time that Zhao Mingyue saw through his true body. It just so happened that they were also planning to do the trick, so Du Jinning simply disappeared smoothly, and disappeared very completely.

Connecting the things before and after, Qi Bokun's grudge against Du Jinning also dissipated.

He also felt that if Du Jinning was missing by herself and was not killed by someone, then she disappeared for half a year without giving Qi Muyuan half a sentence, and she was too sorry for Qi Muyuan. Every time he saw his grandson's uncomfortable energy, Qi Bokun complained a little more about Du Jinning.

Now that the royal family knows her identity as a woman, Qi Bokun naturally will not complain about Du Jinning. Especially after knowing that the yield of high-yielding rice has been reduced by two and a half stones.

A gentleman does not stand under the wall, Du Jinning's decision is right. Now is not the time to come back, and she can't bring any letters to the Qi family, so as not to arouse Zhao Yu's suspicion of the Qi family's ancestors and grandchildren.

She was genuinely good for them.
