In Xu Qilin's positioning of Dayingku, except for glass, mirrors, and steel, other industries are only a demonstration for the time being.

For example, the manufacture of wool spinning, cotton spinning, and even white sugar and rock sugar will also gradually open up technology to promote the establishment and development of non-governmental enterprises.

Of course, this is not something that can be done in a short period of time. Wool spinning and cotton spinning, on the other hand, will have the conditions for promotion to the people within two or three years.

said that it was far away, Xu Qilin sent Zhou Qi away, and told her that if there was anything difficult, she could write to him.

In Dayingku's organization, if there are suggestions for technological innovation and improvement among officials and technicians, they can be reflected to Xu Qilin through channels.

The letter to Zhou Qi opened another convenient door, and the letter could be marked as innovation or improvement and sent directly to Xu Qilin.

Do good deeds, Lao Tzu likes this.

After Xu Qilin inspected Dayingku's workshop, he saw more grateful eyes and a respectful attitude towards him. These female workers were all freed because of him.

Leaving the workshop, Xu Qilin returned to the yamen and inspected and supervised the preparations for spring ploughing.

Last year, because of the conquest of Gaochang, tens of thousands of government soldiers were used to reclaim the land for planting. This year, neither the population nor the labour force has reached that number, and the area under cultivation has increased, but not by much.

But even so, because of the experimental planting in Hebei and Henan last year, it also received good results.

This year, with the large-scale promotion of these two places, coupled with Lingnan cotton, the total output of the country will still nearly double.

As long as the output continues to grow, the price of cotton textiles will continue to fall and become a popular commodity. Xu Qilin expects that in three to five years, it may reach the level of "no one without clothes".

In order for cotton spinning to become a pillar industry of the country, it also needs the support of the imperial court. From now on, the concern about food cannot allow His Majesty Li Er to completely relax the restrictions on the cultivation of crops.

This is also something that cannot be helped, the level of production and transportation in ancient times makes the resistance to natural disasters still very weak.

But unlike in later generations, trains, planes, and ships, even if they are thousands of miles apart, disaster relief materials will be delivered quickly and will be provided.

Although Xu Qilin's compilation of the seasonal agricultural book is very practical, it has indeed increased grain production and income. But based on food, even he agrees with and supports it.

Cash crops can be more profitable, but the area under cultivation must be limited. Having surplus grain in a warehouse is the foundation for maintaining social stability.

This migration to Hexi not only alleviated the contradiction of a large number of people and a narrow land in Guanzhong, but also created millions of acres of farmland in Hexi. Coupled with the gradual development of Jiangnan and other places, the country's grain output has increased by nearly 50 percent.

The support of these data undoubtedly made His Majesty Li Er's confidence soar. The inspection of the two provinces of Hebei and Henan was more thorough and strict, which made Xu Qilin believe that His Majesty Li Er had turned his attention to Liaodong.

Maybe it won't last long to stay in Beijing, and then he will be transferred to Hebei Province again. It symbolizes that the war of Gaochang is backed by the development and construction of Hexi, and the attack on Goryeo, Hebei Province will also play the same role.

Calculate the time, if there are no accidents, it is really about the same.

Xu Qilin carefully recalled the historical war against Goguryeo and found that the Tang Dynasty did not get much benefit.

The first expedition to Goguryeo, His Majesty Li Er drove the expedition in person, although Goguryeo was severely damaged, but he was defeated and withdrew his troops under the city of Anshi.

In the following years, the Tang army continued to attack Goguryeo with harassing tactics, causing it to lose its troops and lose its troops, and it was exhausted to cope, and the food shortage brought it to the point of collapse.

By the time of Lee's reign, the Tang army continued to weaken Goguryeo and eliminated its important ally, Baekje, leaving it alone.

In the Qianfeng period, after more than ten years of frequent attacks, Goguryeo was already exhausted and weak, and was finally destroyed by the Tang army in one fell swoop.

But with the fall of Goguryeo and Baekje, the last cheap one was Silla, who had always seemed obedient and constantly asked the Tang Dynasty for help.

When Tubo rose and captured the four towns of Anxi, the Tang army had to transfer troops to the northwest and launched a long and difficult war with Tubo.

Silla, a white-eyed wolf, took the opportunity to collude with the remnants of Goguryeo to raise troops against the Tang Dynasty, and attacked the Xiongjin Governor's Mansion established by the Tang in Baekje's hometown and captured 82 cities.

Later, the Tang army also counterattacked Silla, but it was caught in a two-sided battle with Tubo and Silla, and was unable to destroy Silla.

In Xu Qilin's opinion, Silla is definitely an acting school, and it is not an exaggeration to get a little golden man.

When the strength was insufficient, Silla was low and small, like a good grandson, and always used the might of the Tang Dynasty to resist the invasion of Goguryeo and Baekje.

When the wings were full and the international situation around the Tang Dynasty was not good, Silla turned against the negative grace, and the rogue face was exposed.

Again, there are no eternal friends between countries, only eternal interests.

In fact, if the rulers of the Tang Dynasty are evaluated as naïve, of course, it is wrong.

No one has a front and rear eye, like the Tang Dynasty giving marriage to Tibet, and maintaining peace for 30 years, who can know that it will become a long-term enemy of the Tang Dynasty?

The same is true of Silla, if the Tang Dynasty continues to be strong and does not give it a chance, it will still obediently become a vassal state.

As for the reason for the outbreak of war between the Tang Dynasty and Goguryeo, in addition to His Majesty Li Er's desire to repeat the homeland of China, there are also factors such as Silla's request for help.

As the boss, for the sake of the younger brother, His Majesty Li Er sent troops to attack Goguryeo, which can be said to be justified, or it can be said that he found an excuse.

Since the outbreak of war was inevitable, Xu Qilin could only strive for a change in strategy. It doesn't seem to be the best strategy to conquer Goguryeo in one fell swoop, the population base of the Tang Dynasty is there, and it is difficult to stabilize the occupation.

What about hitting Goguryeo hard, driving Goguryeo's sphere of influence back to the south of the Yalu River, and letting Goguryeo continue to fight with Baekje and Silla, while the Tang Dynasty looks across the river, can it take advantage of the fishermen?

Wouldn't it be beautiful to wait until these three small countries are almost pinched, and then Datang will take advantage of the situation and destroy them all in one fell swoop?

Xu Qilin thought about it and felt that it was very feasible, so he couldn't help pinching his chin and laughing evilly.

Of course, this strategy may not be in line with His Majesty Li Er's thoughts. He is so famous, the merit of destroying the country and restoring the old land is one of his life goals, how can he not compete for the whole merit?

What excuse can you think of for this? Xu Qilin fell into deep thought.

……………

The capital of Chang'an, the East Palace.

Li Chengqian did not move to Daming Palace, but felt more free because his father was far away.

However, Li Tai was greatly rewarded for the compilation of "The Chronicles of the Ground", but he felt extremely unhappy, and even felt that his father's favor had been transferred to his fat brother.

The right to inherit the throne is a little hanging, and although His Majesty Li Er does not show any words to the outside world, Li Chengqian can still sense the threat.

Although His Majesty Li Er appointed him a stricter teacher - Wei Da Troll. But Wei Da Troll was already seriously ill, unable to do his best, and could not supervise from time to time, so his impact on Li Chengqian was not great.

Making this decision, His Majesty Li Er seems to be telling outsiders that he has no easy heart to save, and he still has high expectations for the crown prince.

But Li Chengqian didn't think so, he felt that this was his father's last salvation and his last chance. Obviously, he didn't cherish this opportunity, but he was resentful of his father's spoiling of the fourth brother and sending Wei Da Trolls.

Since he has made himself the crown prince, why did he give all the praise and rewards to the fat brother, and why did he send all the teachers who were stricter than the other to him?

What if you're really ruined?! As soon as Li Chengqian thought of the fate of the abolished prince in history, he felt a chill in his back and shuddered.

Whether to sit back and wait for death, or give it a go, is now in front of Li Chengqian. It seems that there are only these two paths, life or death, and there is no other choice.

He only thinks about how others are, but never looks for problems in himself, this is Li Chengqian's character.

His Majesty Li Er praised Li Sipang at the same time, and also issued an edict that "from now on, the emperor will use the treasury, and the department should not be restricted". In other words, Li Chengqian was given a blank check that could be filled out at will.

If Li Chengqian still has a little bit of enlightenment, he should bow down again and again. Even if you spend it, it won't be too much.

But he was hopeless, and with his father's special approval, he tried his best to lose. History: "Before the sixtieth century, the use of goods has exceeded 70,000. ”

You must know that Li Chengqian, as the crown prince, will definitely not be less. And the 70,000 yuan he spent was all unplanned expenses, which was poor.

And such extravagance and waste naturally aroused the dissatisfaction and exhortation of the courtiers. Zhang Xuansu, another teacher of Li Chengqian, played a chorus to criticize the prince's arrogance.

Li Chengqian didn't feel that he was wrong, and sent a killer again, ordering him to take advantage of Zhang Xuansu's early dynasty to "hit him with a big horse and kill him a few times." ”

Well, Du Zhenglun was demoted out of Beijing because he couldn't educate Li Chengqian; This time, Mr. Zhang was beaten to almost death.

If you add that Li Chengqian sent a killer to kill Yu Zhining and failed, there are already three teachers planted on Li Chengqian's rotten wood.

And the killers Zhang Sizheng and Su Gan Chengji sent by Li Chengqian saw Yu Zhining's "bitter bed" and couldn't bear to kill him. Compared with Li Chengqian's ruthlessness and viciousness, it is more humane.

Do you say that Li Chengqian's various behaviors are worthy of being the prince? still thinking about inheriting the throne and doing whatever he wants, it's really wishful thinking and self-defeating.

If Li Chengqian is really allowed to ascend the throne as emperor, with his cruelty, it will definitely be a disaster for the Tang Dynasty.

How could His Majesty Li Er let the Tang Dynasty that he had worked so hard to build be destroyed in the hands of Li Chengqian? Li Chengqian's various behaviors have made His Majesty Li Er's salvation all come to naught, and Yi Chu is actually an unchangeable thing.

And Li Chengqian is not only unrepentant until now, but also dreaming. He thought that if he killed the fat brother who had been in his old age for many years, the throne would fall firmly on his head.

But how can the words of killing my brother be said clearly, at least not yet. However, Li Chengqian's obscure words still shocked his cronies, and no one dared to answer easily.

Seeing that no one was silent, Li Chengqian had no choice but to speak by name.

His gaze first shifted to Du He, paused for a moment, and then looked at Zhao Jie, feeling that this guy was more positive and should be able to understand what he meant.

Li Chengqian reluctantly eased his breath and asked, "Ah Jie, how do you think you should deal with it at the moment?" ”

Zhao Jie's eyelids jumped, pretending to be thoughtful, and only replied after a while: "Your Highness, the King of Wei has not made friends with his ministers, and he must not have the heart to conspire. The lower officials think that there is no need to act rashly at the moment, and it is the best policy to wait and see. ”

Li Chengqian spewed out a heavy breath from his nostrils, very dissatisfied with Zhao Jie's words. Still wait and see, the crown prince's position is going to be lost, can't you see it?

Du He didn't see Li Chengqian's killing intent, but he didn't want to be this bird, but he still wanted to show his wisdom, so he said slowly: "To deal with King Wei, the lower officials have a plan." ”

"Say it quickly." Li Chengqian's eyes flashed, and he hurriedly urged.

Du He smiled faintly and said, "Your Highness can send someone to collect the accusations of King Wei, sort them out and write them at the noon gate." ”

Li Chengqian was a little disappointed, but he still asked patiently: "This move is quite time-consuming, and it is not yet known whether the charges can be collected." ”

Du He said firmly: "Your Highness, don't worry, the accusation will definitely be collected." ”

Li Chengqian groaned slightly, and also understood what Du He meant. False accusations, just make up some crimes.

Although he did not appreciate this method very much, Li Chengqian felt that it was okay to give it a try. If it fails, and then the assassination is revealed, I believe that there will be no excuse for his subordinates to shirk.

Thinking of this, the expression on Li Chengqian's face relaxed, and said, "Then I'll leave this matter to you, how about it?" ”

Du He bowed down to receive the order and said, "Your Majesty will do your best to share your Highness's worries." ”

Zuotun Wei Zhonglang General Li Anyan was Li Chengqian's eyes and ears in the palace, and said at this time: "The lower officials think that His Royal Highness should envelop the courtiers and officials with heavy money to strengthen his momentum. Hou Junji was imprisoned for destroying the country, perhaps with resentment, and it seems that he can be co-opted. ”

Li Chengqian thought for a while and said, "This discussion is very good. There is Helan Chushi in the East Palace, and it can also be matched. ”

"Your Majesty once wrote "Wei Feng Fu" to Zhao Guogong." Du He arched his hand and said: "Zhao Guogong is also a nephew and uncle of His Royal Highness, if Zhao Guogong is inclined to His Highness, his words will be valued by His Majesty." ”

"Wei Feng Fu" is the work of His Majesty Li Er, the main content is to remember the difficulties of establishing the royal industry, and to show gratitude to the heroes.

And this "Wei Feng Fu" was given by His Majesty Li Er to the eldest grandson Wuji, showing his gratitude to his eldest brother for his life.

Li Chengqian was silent, as a nephew, his relationship with the eldest grandson Wuji's uncle was very ordinary.

Moreover, the eldest grandson Wuji is treacherous and treacherous, and does not show any preference for any prince. Even for the crown prince Li Chengqian, the eldest grandson Wuji kept his distance.

Of course, the position of the eldest grandson Wuji in the mind of His Majesty Li Er is indeed one of the best. If he can help Li Chengqian, he will naturally be the heaviest bargaining chip.

"If Your Highness is in a difficult situation, you can also start making friends with Sun Chong, the captain of the Horse Commander." Zhao Jie finally interjected at this time and said, "A certain and eldest Sun Chong still have a little friendship, so they can be tested. ”

Li Chengqian nodded and said, "Then you will have to work." ”

Zhao Jie bowed and said: "Serving His Highness, the duty of an official." ”
