Since Li Zhi was appointed as the crown prince, Li Shimin has done his best to educate the prince, and when he saw that the prince was about to eat, he asked: "Do you know the truth of eating?" Li Zhi respectfully said: "I don't know! ”

Li Shimin said: "It is very difficult to open up the wasteland and farm, and it takes manpower to reclaim it, if you don't seize the farmer's uncle's agricultural time, let them have surplus grain in all seasons, and you will always have such a fragrant meal to eat!" ”

Seeing the prince riding a horse, Li Shimin asked again: "Do you know the truth of riding a horse?" Li Zhi respectfully said: "I don't know! ”

Li Shimin said: "Horses can replace the labor of walking on foot, if you let it rest on time and don't let it overwork, you can always have a horse to ride." ”

Seeing the prince riding a boat on Weishui, Li Shimin asked again: "Do you know the truth of boats?" Li Zhi respectfully said: "I don't know! ”

Li Shimin said: "The boat is like the emperor and the crown prince, and the river is like the people of Limin, the water can carry the boat and also capsize the boat." You have only been the prince for a short time, so you must be careful! trembling, if it is deep and decaying; Be cautious every day, think good from the beginning to the end. ”

Seeing the prince sitting under the crooked tree resting, Li Shimin asked again: "Do you know the truth of this tree?" Li Zhi respectfully said: "I don't know! ”

Li Shimin said: "Although the tree is curved, it can be turned into an upright wooden strip after being sawed with an axe by a carpenter, measured with an ink rope, and then processed." Even if the emperor has no way to govern the country, if he can humbly seek advice from the virtuous, he can also become a saint! Li Zhi suddenly realized.

On February 12, the 19th year of Zhenguan, Li Shimin personally commanded the Sixth Army to set out from Luoyang to expedition to Liaodong, let Li Zhi accompany him, and ordered Xiao Yu to stay in Luoyang.

Li Shimin's reason for conquering Liaodong was: Yuangai Suwen killed his monarch Rongliu Wang Gaowu, self-proclaimed Mo Lizhi, brutalized the people, and violated the edict of the Tang Emperor to invade the neighboring country Silla, so he could not help but crusade.

In fact, he did not say a more important reason: that is, Li Zhi is like a sheep, surrounded by tigers and wolves, I am afraid that he will not be able to control the Tang Empire well in the future, in order to ensure the long-term peace of the Tang Dynasty, he must take advantage of the opportunity that he can still lead troops to fight to help Li Zhi cut off the great trouble of Goguryeo.

On March 9, Luan Yu arrived in Dingzhou, and the crown prince Li Zhi was in charge of the state in Dingzhou.

On the twenty-fourth day, Li Shimin set out from Dingzhou, personally wore a bow and arrow, tied a raincoat behind the saddle, and ordered the eldest Sun Wuji, Cen Wenwen, and Yang Shidao to accompany him. Gao Shilian, Liu Xun, Ma Zhou, Zhang Xingcheng, Xu Jingzong, and Gao Jifu were in charge of the machine and assisted the prince.

Before, Li Zhi saw that Aya was going to go on an expedition in person, and he was very frightened, and cried sadly for several days.

Li Shimin sighed and persuaded: "Hey, pheasant slave, what are you crying about!" Today, I left you to guard Dingzhou, supplemented by virtuous people, because I want the world to know your style. The key to governing the country is to advance the virtuous and retreat, reward the good and punish the evil, and be selfless, you should strive to promote this way, what is the benefit of always being sad and crying? ”

Li Zhi took out a silk silk to wipe away his tears, choked and said: "The sword is ruthless, the arrows and stones are like rain, Ye Ye is going to bow the armor, kiss the arrows and stones, and face the array of fish scales at night, facing the siege of the crane wings!" The child is in the back of the bell ringing Ding Ding, sitting and enjoying the peace, every time I think about this, the child sleeps and eats uncomfortably, and the guilt is terrified! ”

Li Shimin hugged him, patted him on the back, and persuaded him not to worry too much.

At this moment, the father and son are facing parting, Li Shimin is riding a white hoof, Li Zhi is holding the reins in front, and he still can't bear to say goodbye after sending each other for eighteen miles.

When he came to the long pavilion, Li Zhi hugged Li Shimin and cried, Li Shimin gently pushed him away, pointed to the brown robe he was wearing and said to the prince: "Pheasant slave, wait until I see you again, Ye Ye will change this robe!" ”

Then gritted his teeth, got on the horse, and decisively patted the horse away, Li Zhi waved goodbye with tears, Li Shimin suddenly grabbed the bridle, looked back at Li Zhi, and couldn't help but cry, and the father and son said goodbye.

Outside the long pavilion, the grass is green, covering the ancient road, covering the deserted city, the warm wind of late spring blows through the willows by the river, and the crimson sunset shines on the mountains in the distance.

Li Zhi turned around and embarked on the return journey with Zhang Xingcheng, Xu Jingzong, Gao Jifu and other auxiliary ministers, and the melodious flute of the shepherd boy was heard in his ears.

In the blink of an eye, in the early winter, Li Shimin returned from an expedition to Liaodong,

In Yingzhou, Li Shimin was very excited when he heard that the prince was coming to greet him, and immediately led 3,000 people to gallop into Linyu Pass, and met the prince on the way. The father and son hugged each other and cried excitedly, Li Zhi saw that Aya's brown robe was tattered, and immediately brought new clothes to offer, and Aya happily changed into new clothes.

At the end of the year, due to the long-term absence of Tang Mu, Li Shimin had abscesses on his legs and could not ride a horse, so he walked on foot.

After arriving in Bingzhou, Li Zhi sucked the abscess for Aya with his mouth, and walked beside him for a few days, and the abscess on Aye's leg quickly healed.

On March 7, the twentieth year of Zhenguan, Luan Yu returned to Chang'an. Li Shimin was unwell and wanted to specialize in maintenance, so he ordered the military state to take care of the aircraft and commissioned Li Zhi to execute him.

Li Zhi listened to the government in the East Palace in the early morning, and after retiring from the court, he entered the Taiji Palace to serve medicinal food, and did not leave Aya.

Soon, Chang Dexuan, a native of Shaanzhou, accused Zhang Liang, the secretary of the Criminal Department, of raising 500 fake sons, and talked about the plot with the warlocks Gongsun Chang and Cheng Gongying.

Li Zhi immediately reported it, and Li Shimin ordered Ma Zhou to review the case, and Ma Zhou quickly found out.

It turned out that when Zhang Liang was an official in Xiangzhou, his fake son Gongsun Festival said the proverb "the lord of the bow chief should be Bedang", which made Zhang Liang think that he would become the master of the people, so he went to consult the warlock Cheng Gongying, Cheng Gongying said that he looked like a dragon when he slept in bed, which was unspeakably expensive.

Zhang Liang also talked with the warlock Gongsun Chang, saying that his concubine was destined to become a princess, and Gongsun Chang claimed that Zhang Liang's name was hidden in the diagram.

After learning about the case, Li Shimin said: "Zhang Liang has 500 fake children, what does he want to do with these people?" Isn't that exactly what you want to rebel in? He also ordered hundreds of officials of the imperial court to openly discuss Zhang Liang's case, and almost all of them said that Zhang Liang had rebelled, so Zhang Liang and the warlock were beheaded together in the lively Chang'an West City to set an example.

In the early years of Zhenguan, Tai Bai Xing appeared many times in the daytime, and Tai Shi Ling divination said: "This kind of celestial phenomenon indicates that the heroine is Chang!" The popular "Secret Notes" said: "After the third Tang Dynasty, the heroine Wuwang has the world." ”

On this day, Zhang Liang was beheaded for talking about the diagram, Li Shimin suddenly remembered these nonsensical things, and recalled them carefully, the more he thought about it, the more afraid he became, so he secretly summoned Taishi Cheng Li Chunfeng to interview about the heroine.

Li Chunfeng replied: "According to the celestial phenomena, the minister has calculated that the omen has come true. The heroine has been born, and is already in His Majesty's palace, from today, no more than forty years, when there is a world, the killing of Li Tang's descendants will be exhausted! ”

Li Shimin was so shocked that he couldn't close his jaw and said, "Already in my palace?" Oh my God, how about I kill all the suspects in the palace? ”

Li Chunfeng straightened up and replied solemnly: "Heaven's destiny will be unreasonable." The king does not die, how afraid of vain and innocent! And according to the celestial phenomena, the trend has been completed, and it is in the palace, and it is already a family member of His Majesty. Forty years later, when he is old again, he is merciful when he is old, even if he changes his surname. For His Majesty's descendants, they may not be killed. If the harem is washed with blood today, the heavens will resurrect one, less strong and more poisonous, even more powerful. If this is really the case, she will kill Her Majesty's descendants and leave no one behind! ”

Li Shimin was so shocked that he leaned on the throne, looked up at the starry sky, sighed, and said, "Hey, why does God treat me like this? Could it be that the Xuanwu Sect kills too much? Maybe I'm just alienating all the people with the surname Wu! ”

Li Chun bowed down and said: "Your Majesty can walk with the sky, and you will be able to enjoy the national glory for a long time!" ”

Li Shimin nodded, and planned in his heart that no palace people surnamed Wu would be allowed to accompany him when he visited various places in the future, and even expelled all the people surnamed Wu from the palace in the harem.

In April of the twenty-first year of Zhenguan, Li Shimin suffered from wind disease, could not stand the summer heat of Chang'an, and ordered Yousi to build the Zhongnan Mountain Taihe Waste Palace for Cuiwei Palace, and soon, Yuhua Palace was built in Phoenix Valley of Yijun County.

In the first month of the twenty-second year of Zhenguan, Li Shimin personally wrote the twelve articles of "Emperor Fan", gave it to Li Zhi to study, and admonished him: "Self-cultivation and governing the country are prepared in it." You have no merit but want to inherit my wealth, you should worship goodness and virtue, and you should not be reckless! ”

A few days later, Li Shimin held a banquet in the Shenlong Hall to entertain the generals of the Northern Ya Forbidden Army.

Zuo Wuwei General Li Junxian reported the nickname "Five Niangzi", Li Shimin's tiger body was shocked, and the words "heroine Wuwang" flashed in his mind.

Li Shimin forced his composure, and suddenly laughed and said, "Where did the woman come out?" So brave! Everyone laughed and said, "How can such a mighty man with bearded eyebrows choose a female name?" Li Junxian didn't care.

After the banquet was dispersed, Li Shimin immediately checked Li Junxian's file and found that he was a native of Wu'an County, a general of Zuo Wuwei, a county prince of Wulian, and stationed at the Xuanwu Gate of Taiji Palace. "Heroine Martial King" is not him, who else can he be?

Li Shimin was overjoyed, this is really a nowhere to find a place to step on the iron shoes, and it takes no effort to get it, Wow, he immediately transferred Li Junxian to the assassin of Huazhou, and planned to wait for an opportunity to kill him after he was transferred.

After taking office in Huazhou, Li Junxian followed the Huazhou warlock Daoxin to practice the art of Bigu.

The imperial historian who was in charge of monitoring him said that Li Junxian colluded with the demon Dao Xinqian and plotted against him. Li Shimin immediately issued an edict to kill Li Junxian.

After killing Li Junxian, Li Shimin was relieved, and finally eliminated the trouble for the lovely pheasant slave, so he canceled the plan to expel the people surnamed Wu in the harem, but still did not allow the palace people surnamed Wu to follow him to Cuiwei Palace and Yuhua Palace for vacation, which has become an unspoken rule known to everyone in the harem.

In April of the twenty-third year of Zhenguan, Li Shimin traveled to Xingcuiwei Palace and said to Li Zhi: "Li Tao is more than intelligent, but you have no kindness to him, I am afraid you can't convince him." I first ordered him to be deposed, and if he went to office immediately, after ten thousand years, you could use him as a servant; If he wanders, he should be killed! ”

On May 15, he deposed the crown prince Zhan Shi Li Tao as the governor of Diezhou; After Li Tao received the edict, he immediately went to work without going home, obviously seeing through the emperor's intentions!

After this was done, Li Shimin's illness worsened, and Li Zhi was very sad, waiting day and night, not leaving his side, and even unable to eat for several days, and white hair appeared on his head.

Li Shimin was also moved to tears when he saw Li Zhi being so filial.

On the twenty-sixth day of May, Li Shimin summoned the eldest grandson Wuji and Chu Suiliang into the bedroom of the Hanfeng Hall of Cuiwei Palace, and said: "I know that I will pay the public in the future. The prince is benevolent and filial, the public knows, tutor him well! ”

He also said to Li Zhi: "Wuji, Suiliang is here, don't worry about the world!" He also said to Chu Suiliang: "Wuji is loyal to me, I have the world, and I have more power." I die, and don't let slanderers separate him. ”

In the end, Chu Suiliang was ordered to draft an edict: the crown prince is located in front of the coffin, and the funeral discipline should be in the Han system. Soon, Li Shimin died in the Hanfeng Hall of Cuiwei Palace.
