The banquet was originally a joyful atmosphere, although Li You was killed and Li Chengqian was mismatched, no one would talk about it at the banquet invited by Li Sipang.

It's just that Li Zhi's expression seems a little depressed, as if something is pressing on his mind.

Xu Qilin and others can see it, but who is embarrassed to ask?

Only the eldest grandson Chong felt that the relationship was good, and only after the third round of drinking did he ask teasingly: "His Royal Highness the King of Jin, is there anything troublesome in the house?" Or which little lady did you fall in love with, so you don't belong to your heart? ”

Xu Qilin and Tang Yizhi both laughed, making the atmosphere more relaxed, which diluted the meaning of the inquiry and turned it into a teasing joke on the wine table.

Li Zhi, the king of Jin, shook his head with a wry smile and said, "There are troubles, but they are not what the eldest grandson said. ”

As he spoke, he turned to Xu Qilin and asked, "Qi Lin, if you say that you have walked the most places, you are the one here." Let's talk about the most promising places and the most comfortable places to feel at ease? ”

Xu Qilin pondered for a moment and said: "If you say that you are at ease and comfortable, such as the identity of Your Highness, where you go is also a pavilion and a palace, and there are people waiting for you." In addition to the desert grassland, a certain can't think of a place that is too difficult. ”

After a pause, he continued: "The family teacher has a saying: this place of peace is hometown. With such a mentality, the tutor travels around, and he does not feel bitter. ”

Li Zhi nodded and exclaimed: "I am also admired for being able to make Lu Yu Immortal so free and easy." ”

"Doesn't Qi Lin also have a plan to travel far, the most promising place mentioned by His Royal Highness Jin can be within your itinerary?" Eldest Sun Chong continued to ask.

Xu Qilin nodded and said, "I think that the development prospects of Hebei Province and Henan Province are the most impressive, and they will also be the focus of the imperial court's attention. Dayingku has already done experiments, and these two dishes are very suitable for growing cotton. ”

After destroying Gaochang and opening up the Western Regions, the most direct enemy was Goryeo. His Majesty Li Er's ambition is known to many people.

And to conquer Goryeo, Hebei and Henan will inevitably become logistics bases. This is the same reason that before the fight against Gaochang, the imperial court focused on the development of Hexi.

Cotton is a good product to keep out the cold, and the bitter cold in Liaodong will become an important military supply. According to the current planting area, the scale of planting in Hexi alone is obviously not enough.

Tang Yizhi shook his head again and again, and said, "What Qi Lin said is extremely true. The benefits of cotton are really eye-catching, and I heard that there are big families who send people to Longyou to operate, and cotton is the first choice. ”

Are the fields in Hexi no longer enough to be developed? Xu Qilin blinked his eyes and quickly figured it out.

For the crops planted, the imperial court had some restrictive regulations. There are only remote places like Hexi and Longyou that can be cultivated relatively freely.

After several years of development in Hexi, there are not many large fields, and Longyou has naturally entered the sight of the family. They have the financial resources and manpower, and they are indeed able to operate in the Longyou enclosure in order to reap the great profits of cotton.

In this regard, Xu Qilin is happy to see it. What land annexation, in his opinion, will not work by restraint alone. The law of historical cycles also illustrates this point.

The territory of Datang is so vast, and there is more land to be developed and undeveloped. Enclosure farming, even if the price of cotton falls, is a stable income for the family.

But there is one problem that will get worse, and that is labor. It is certainly too late to rely on the natural reproduction of the population.

What Xu Qilin thought of, the family would also think that under the joint promotion, the criminal slave trade may not be far away.

In fact, Xu Qilin has set a precedent in the operation of Dayingku. In coal mines, iron factories and other workshops, there are many slave laborers.

Of course, Xu Qilin painted a big pie to make those slave workers feel like they had a head. In terms of treatment, Xu Qilin was not too harsh.

But the demand for slave labor is increasing, and where is there any other way than to plunder foreign wars?

Therefore, Xu Qilin raised his hands in favor of the conquest of Goryeo. The recovery of the old land of the Han Dynasty was one of them, and it was also indispensable to obtain a large number of prisoners of war as slave laborers and contribute to the construction of the Tang Dynasty.

There is no need for Xu Qilin to remind him, it is estimated that many people have already set their sights on this transaction, and will even grab business with Xu Qilin.

Li Zhi listened to Xu Qilin's explanation, bowed his head slightly, and also agreed, and said slowly: "I have grown up, and I also want to go out to work in the domain, understand the people's suffering, and benefit the people. ”

The eldest grandson blinked his eyes and asked, "After asking Qi Lin, His Highness has already decided?" ”

Xu Qilin said with a smile: "Your Highness has already made a decision, but I just want to confirm it with you." ”

Li Zhi smiled and said, "Qi Lin explained that he benefited a lot, and he finally made up his mind. ”

Xu Qilin knew that Li Zhi should have been touched, Li Chengqian's rebellion had a great impact, and Li Zhi and Li Yuanchang were good friends. Li Yuanchang was given death, does Li Zhi have any thoughts if he is not worried about the fourth brother?

Moreover, he has been delayed in becoming a vassal, although it is the favor of his father, but it is not in line with the law. The ministers were admonished because Li Sifat was stranded in Beijing at the beginning, and if he followed suit, wouldn't it make people think that he had the heart to seek succession?

Therefore, in order to avoid suspicion, he must make a gesture, regardless of whether His Majesty Li Er will agree or not.

Of course, Xu Qilin knew that His Majesty Li Er had already reflected on it, and it was quite possible to agree. Although the three sisters-in-law are all equally favored, for the sake of the stability of the Tang Dynasty, His Majesty Li Er should know how to choose.

"I heard that Qi Lin's medical skills are very good, can you take the time to diagnose and treat Her Royal Highness Princess Yuzhang." Tang Yizhi diverted the topic and looked at Xu Qilin expectantly.

The eldest grandson Chong smiled and said: "Qi Lin's medical skills are excellent, His Royal Highness Changle told His Royal Highness Yuzhang that Qi Lin should not refuse!" ”

Xu Qilin smiled bitterly and said: "I don't dare to say that I am clever, and I am also worried about diagnosing and treating people, for fear that there will be a mistake, and if the treatment fails, it will hurt people." ”

Tang Yizhi arched his hand and said: "There is Her Royal Highness Princess Changle in front and Her Royal Highness Princess Jinyang in the back, no matter how humble Qi Lin is, he can't say it." ”

Li Zhi also echoed: "My son is seriously ill and dying, and my father and a certain emperor are worried, thanks to Qi Lin. Her Royal Highness Princess Yuzhang is also sickly and weak, and Qi Lin must use another trick. ”

Princess Yuzhang also died early, and His Majesty Li Er was very sad, and even passed through filial piety, which frightened the ministers.

Aside from this reason, Xu Qilin is still very enthusiastic about saving lives and helping the injured. Whether it is Changle, his son, or Yuzhang, they are all at the age of flowers, and he can't bear to see them die early.

Seeing Xu Qilin nodding in agreement, Tang Yizhi's expression relaxed, he had no friendship with Xu Qilin, and today was the first time they met.
