Four years of Tang Wude, Chang'an. The chickens and dogs jumped up and down the East Palace, and it was a mess. Li Jiancheng's eldest son, Li Chengzong, the king of Taiyuan County, has been ill for more than ten days.

The imperial doctors of the palace were all helpless, and they saw that the king of Taiyuan County was about to die.

Li Chengzong, in June of the third year of Wude, was named the king of Taiyuan by Tang Gaozu Li Yuan. It has only been half a year since there was such a catastrophe, and the superstitious saying is that Li Chengzong himself did not have the life of great wealth and nobility, and he could not bear the grace of heaven.

The same is true in history, the eldest son of the crown prince Li Jiancheng, died young.

At night, when everyone was in a hurry to sleep, the little palace maid who was in charge of taking care of Li Chengzong was frightened. ran wildly along the way, shouting in his mouth: "The king of Taiyuan County is killed, the king of Taiyuan County is killed."

Li Jiancheng and the crown princess Zheng had just laid down when they heard shouting outside that Li Chengzong was killed.

In the night of the East Palace, there was another big chaos.

When Zheng heard that Li Chengzong had died, a fleeting smile appeared on his face. The eldest son is not a descendant, which is not a good thing. Besides, without Li Chengzong, his son Li Chengdao is the de facto eldest grandson, the future emperor of the Tang Dynasty.

Thinking of this, it is understandable for Zheng to smile.

When he came to the palace of Li Chengzong, Zheng wanted to show the role of a loving mother. She just threw herself down in front of Li Chengzong's bed, ready to cry to mourn her dead childhood.

Suddenly, Li Chengzong opened his eyes, held his head with one hand, and slowly sat up, muttering something in his mouth, and fainted again after a while. This time, the whole room was scared, and Zheng was even more stunned on the spot.

Li Jiancheng hurriedly asked people to carry Zheng down, and shouted at the imperial doctor: "Will you see a doctor or not, if you can't explain today's events, you don't have to get out alive, lest quacks mislead people."

"The ministers are guilty" The imperial doctors hurriedly knelt down, although the words of the crown prince Li Jiancheng were not good, they also had to bear it! Besides, to a certain extent, Li Jiancheng is really polite, I didn't say anything if you couldn't cure my child's illness, and I didn't say anything when you said that my child died, but this dead and alive scared my wife out, so I can't help but say something, right?

An old imperial doctor stepped forward to check Li Chengzong's pulse again, and carefully examined it, with a blank face.

Li Jiancheng looked at it and asked, "What the hell is going on?"

The imperial doctor said: "The pulse of the king of Taiyuan is stable and strong, and there is no serious illness."

When Li Jiancheng heard this, he repeatedly asked the imperial doctor to make sure, and then said: "You are also considered meritorious, go down and receive the reward."

"Thank you, Your Highness the Prince."

Li Chengzong on the bed was still struggling, although his face was expressionless, his mind was overturned.

The second day, at noon.

Li Chengzong woke up early in the morning and recovered from a serious illness. Li Jiancheng asked him to rest in the hall.

"When has this been, the change of Xuanwu Gate! When the time comes, the whole family will be gone, and they will be able to rest forever. Li Chengzong muttered in his heart.

Li Chengzong walked out of the door, and couldn't help but scold: "Dean! Dean! You said that you are such a learned person, what kind of name do you give me, call me Li Chengzong. Now, even if I dodge a plane crash, I have to face the butcher's knife of Li Shimin, the first emperor of the ages. ”

In fact, Li Chengzong did not know the specific time and process of the Xuanwumen Change. He is a college student who graduated from science and engineering, and his knowledge of history is really a little shallow.

Li Chengzong was walking, but he saw a fast horse galloping towards him. The man on the horse was very familiar, and it seemed that he had some impression in the memory of last night.

"Boy, I heard that you almost died yesterday, and you were pulled back by those imperial doctors, didn't you?" The person who spoke immediately, vigorous and heroic, with sword eyebrows and starry eyes, was Li Yuanji, the king of Qi.

"Meet King Qi." The surrounding slaves and maids said in unison.

Li Chengzong was not stupid, and hurriedly bowed down and said, "Little nephew to see Uncle Wang." The little nephew walked around the ghost gate yesterday, and he was able to come back to life thanks to the imperial doctor in the palace. ”

Li Yuanji said: "It's okay, you are recovering from a serious illness, so you should go back and recuperate."

Li Chengzong thought to himself: "What a good brother!" Even the words they said were the same, and their tones and demeanors were so similar, no wonder the two of them could die together. ”

Li Yuanji patted the horse away, Li Chengzong looked at the horse, and suddenly asked, "Why doesn't that horse have a horseshoe."

Zhu Neng immediately stepped forward and said, "Lord Wang, horses have always been like this, and the slave never knows what a horseshoe is."

Li Chengzong looked back and saw that it was a fat eunuch who had followed him since he got up early in the morning. In fact, obesity was a symbol of wealth during the Tang Dynasty, and the common people who couldn't eat even joked about it, where did you get fat.

"What's your name?" Lee Seung-jong pretended to have forgotten.

"Lord Wang, the little one is called Zhu Neng." Zhu Neng replied with a smile on his face.

Li Chengzong said excitedly: "Don't call yourself Zhu Neng, I'll change your name."

Zhu Neng hurriedly knelt down, and immediately burst into tears, and said with a crying voice: "Thank you for the name." I have been staying by the side of the king of Taiyuan for three years, and I have finally been appreciated by the king of the county, and I will see who in this palace will dare to bully us in the future.

"Zhu Bajie, how about this name?" Li Chengzong asked. “

Okay, good, of course it's good from the king. Zhu Bajie kowtowed.

Li Chengzong was busy early in the morning with charcoal in his hand sketching on paper.

In the afternoon, he personally supervised and asked the best blacksmith in the East Palace to knock out the first horseshoe in the jingling bell. The horseshoe is rumored to have been introduced from Europe in the late Tang Dynasty and was widely used in the Song and Yuan dynasties. However, it is now the Tang Dynasty, and the horseshoe is still a unique rarity.

Cavalry, horses are used many times and fiercely, and it is the most common thing for horseshoes to be damaged, and they must be eliminated if they are damaged, which is one of the reasons why cavalry is not easy to raise.

Taiji Palace, Liangyi Palace. Li Yuan is also fine today, and when he heard that Li Chengzong, the king of Taiyuan County, asked to see him, he naturally agreed. However, I wondered in my heart, sometimes I can't see him twice a year when I find an eldest grandson, and I saw him once last year when he was named the king of Taiyuan County.

What can he do with himself?" The grandson visits the emperor's grandfather. Li Chengzong said respectfully. Excuse me. I heard that you were seriously ill a few days ago, are you all well now?" Li Yuan asked.

Li Chengzong hurriedly replied: "Thank you for the emperor's concern, thanks to the emperor's grandfather's grace, the grandson can be healthy." How to say it! Sometimes it's not a bad thing to tell a lie.

Li Yuan has been made dark by his two sons in the past few years, and suddenly a grandson wants to thank him, regardless of whether it is true or false, he is still a little moved. Li Yuan laughed and said, "That's good."

Li Yuan saw what Li Chengzong was holding in his hand and asked, "What is in your hand?" Treasure, a heirloom treasure, the grandson is here to present the treasure to the emperor's grandfather today. Li Chengzong replied loudly.

Li Yuan smiled secretly, thinking to himself: "What kind of treasure can a few pieces of broken copper and iron be, but it is not good to hit an eleven-year-old child."

"Then tell Grandpa Huang, what kind of treasure is this?"

It didn't matter what Li Chengzong said, first five minutes to warm up, and then ten minutes to lay the groundwork, until Li Yuan was confused, he said: "Nailing this horseshoe to the horseshoe can reduce the wear and tear of the horse's shoe and greatly reduce the consumption of the war horse."

Who is Li Yuan? He is also the founding emperor, not to mention the eloquence and strategy, but also the ability to write and martial arts, how can he not understand the role of this horseshoe after listening to such a large list of Li Chengdao.

"Hurry up and send the crown prince, King Qi and Pei Lin into the palace." Li Yuan ordered.

Li Chengzong thought that he had earned this credit, but when he thought of Xuanwumen, he was depressed.

When Li Yuanji heard Li Chengzong say that it was because he saw himself riding a horse and saw the raised horsepaw that he had the idea to invent the horseshoe. I consciously stood up, on the one hand, I praised Li Chengdao, and on the other hand, I always praised my own inspiration.

Li Jiancheng is even happier, he is almost out of breath when he is pressed by Li Shimin every day, and it is not easy to be happy.

Li Yuan said: "Grandson, you have made such a great achievement, the emperor and grandfather will promise you whatever you want."

Li Chengzong had already inquired clearly, and heard that Li Shimin was attacking Luoyang, and he planned to bring people to the battlefield to give him a moment behind his back.

Li Chengzong is also really scared, after all, Li Shimin is really majestic, and he doesn't blink an eye when he kills people! Although Li Chengdao didn't know what happened to the Xuanwumen, he understood that he couldn't rely on the prince and the king of Qi, they were really too frustrated.

"Grandpa Huang, my grandson heard that the second uncle was attacking Luoyang, and my grandson wanted to help." Li Chengzong said sincerely. Everyone was stunned, and King Qi was the first to stand still. Because of King Qin's Eastern Expedition, he is also a member of the army, and this time he returned to Chang'an just to dispatch military supplies and grass, and no one knows as well as him how dangerous it is on the battlefield now.

"No, you're too bold." Li Yuanji said.

Li Jiancheng's head shook like a wave drum.

Li Yuan said: "You know that it is very dangerous to fight, and your life may be lost at any time."

Li Chengzong hurriedly said: "My grandson knows the danger, but my grandson, as the Li family, should make contributions to his own career, how can he be greedy for life and afraid of death."

Li Chengzong said this domineeringly, Li Yuan was overjoyed when he heard this, who doesn't want his children and grandchildren to have a future.

"Okay, I will give you 2,000 cavalry to go to Luoyang to help your second uncle, but remember to be careful in everything." Li Yuan said.

When Li Chengdao, the crown prince and the king of Qi retreated.

Li Yuan asked Pei Lian, "What do you see?"

Pei Lin said: "I can't see that it was the prince's arrangement, and it seems that he doesn't know what the king of Taiyuan did today."

Li Yuan said: "I still know what kind of temperament Bishamen has since he was a child, and this matter is by no means his arrangement. He is not a citizen of the world, and he does not have the courage to send his own son to the battlefield. ”

Pei Lin suddenly exclaimed: "The prince doesn't have that courage, that is the prince of Taiyuan County ・・・・・・ himself."

Li Yuan smiled but did not speak.
