For Li Jiancheng, Li Shimin's biggest threat was due to military merits. Due to the need for form, Li Jiancheng could not leave Chang'an easily. The King of Qin could lead his army to fight without any ties.

Now Li Jiancheng finally took advantage of Li Mi in Wagang, and Du Fuwei, Jiangnan, wanted to ask for an alliance, which attracted the main attention of the court and asked Chen Ying to lead his army to support Lingzhou. Li Jiancheng must take full responsibility for whether Chen Ying can succeed.

If Chen Ying can successfully rescue Lingzhou, Li Yuan can also reduce his dependence on Li Shimin. Li Jiancheng naturally does not want Chen Ying to make any mistakes. Chen Ying needs armor, Li Jiancheng takes advantage of his position to exceed Chen Ying's needs, Chen Ying needs craftsmen, and Li Jiancheng also meets Chen Ying without hesitation.

Li Yuan agreed to support Lingzhou at this time, but in fact, Chen Ying invented the down duvet clothing. Because of the emergence of down duvet clothing, it can greatly reduce non-combat losses. However, now the down duvet family in Chang'an City are buying it first, which means that Chen Ying cannot complete the task smoothly.

Li Jiancheng didn't think so when it comes to the huge profits of down duvets. Although down is warm and not as expensive as the best fur, the real nobles still don't disdain to use it, but the high cost is not affordable for ordinary people. Chang'an is crazy about buying down down, which is also very likely Li Shimin was instructing him behind the scenes.

Their real intention of buying down was not to make profits, but to pull Chen Ying's back, and to intensify the conflict between Li Jiancheng and the noble forces of Chang'an.

Chen Ying is not a family member, so he naturally does not understand the real terribleness of the family members. The aristocratic families have been married for generations, and I have you and I have me. They are intricate and complicated, and the so-called killing a chicken to scare the monkey is impossible to talk about. As long as Li Jiancheng dares to raise his knife, it will inevitably make the current situation messy. No matter who is wrong, Li Jian CD will be responsible.

It was naturally not Li Jiancheng's character to surrender. Li Jiancheng asked Zheng Guanyin to wrap a down quilt and personally took it to the residence of Li Gang, Minister of Rites and Prince Zhan Zheng.

Li Gang's concierge was named Li Nianbo, about 40 years old. It is said that those who are close to vermilion are red, while those who are close to ink are black. After listening to Li Gang for more than ten years, although Li Nianbo was just Li Gang's concierge, he was a very knowledgeable person. He was especially good at writing about classics and articles.

When Li Nianbo saw Li Jiancheng, he quickly bowed and bowed, "I am so humble to see His Highness the Crown Prince!"

"The later students came to Li Jiancheng and asked to meet his senior teacher, Mr. Wenji..." Li Jiancheng respectfully saluted outside the Li Gang mansion, where the gate was closed, and signed up.

However, Li Jiancheng's name for Li Gang shocked Li Nianbo. It doesn't matter if he calls his seniors or gentlemen. How could this master be called casually? For thousands of years, only Confucius and Yan Zi are qualified to be called masters. Now, Li Jiancheng called Li Gang the master as soon as he came up. As a senior person who respects Confucianism for the rest of his life, Li Nianbo felt it was unacceptable.

However, Li Jiancheng obviously did not have this kind of ideological burden. He respectfully respected the Hou outside the door, as if a devout disciple was paying homage to the Confucian master.

Li Nianbo shook his head and returned to the inner courtyard to meet Li Gang, conveying Li Jiancheng's words to Li Gang's ears without saying a word. Li Gang sighed slowly: "If you treat others with courtesy, you will have something to ask for. It seems that the troubles Prince is facing are quite a lot!"

Li Gang was a famous minister at the end of the Sui Dynasty. He served as the master of three crown princes of the Sui Dynasty and Tang Dynasty. After Li Yuan Jiantang became emperor, he appointed Li Gang as the Minister of Rites and also the Secretary of the Crown Prince. Although Li Jiancheng was the crown prince, he was still a student in front of Li Gang.

Li Jiancheng saluted Li Gang respectfully with a pious look on his face: "I will pay homage to my senior teacher, Mr. Wenji!"

"You must never be a master!" Li Gang said: "It seems that the goal is quite big if you can make His Highness the Crown Prince condescend and surrender to the nobles!"

Li Jiancheng said with anger: "Mr. Wen Ji knew the general principles and the classics and history. If Mr. Cheng Ji was not a master, who could be the best in this world!"

There is a saying that everyone carries a flower sedan chair. Although Li Gang is not good at wealth, he loves false reputation. Li Gang said with a straight face: "Your Highness the Crown Prince, don't want this, you want to make people laugh!"

However, Li Gang's eyebrows and eyes could not hide his excitement and joy.

Li Jiancheng smiled slightly and understood it. So he told Li Gang about the Chang'an family robbing down for personal gain.

After hearing Li Jiancheng's words, Li Gang slapped the table and said, "It should be killed, but it should be killed. The Tang Dynasty is now a troublesome. All the gentry have the responsibility to stabilize the country. In order to seek personal gain, they sit down and watch the soldiers in the army endure the cold and hunger. I have no choice but to pay responsibilities!"

Although Li Gang was just a minister of the Ministry of Rites in the Tang Dynasty, Li Gang had a very good reputation. Even Kong Yingda was not as high as Li Gang. In the court, Li Gang represented Qingliu. No matter what family or family background you are, you would be impeached to death.

Li Jiancheng invited Li Gang out, but it was obvious that the court would definitely be lively.

Medical officials were also used in the Tang army, but the number was very small, with about 12,500 talents per army, and one military officer was assigned to each army. Generals who attach importance to the treatment of military camps may also add two help to the military officers. Usually, they can cure headaches, foot pain and training injuries, which is barely enough. When there are a large number of casualties during the war, this little manpower is not enough.

During fierce battles, there are always a few people who die on the spot, most of whom are blood loss or infection after injury, resulting in a large number of loss of personnel. There are many factors that affect the morale of the soldiers. The injured cannot get timely and effective treatment. Instability is not the most important and cannot be ignored.

Of course, the profession of doctors has high requirements for practitioners and has a long training time. Those who are able to train their children to learn to read for a long time are keen on fame. Although the profession of doctors is also respected, it is not included in the category of gentry after all, which has also caused the scarcity of doctors in the world.

After Chen Ying returned to the mansion, he recruited Chen Huairen. Chen Huairen was a beating doctor. In the battle of Jingyang, he learned the skills of treating external trauma with Chen Ying, but now the wounded in the Tang army is not yet the turn of Chen Huairen to take action. In order to make a living, Chen Huairen had to open a small medicine shop in Chang'an City.

Chen Ying looked at Chen Huairen and asked, "Huairen, I haven't asked about it recently, how is your medicine shop now?"

"Don't do it!" Chen Huairen said with a depressed look: "Since winter, there have been a significant increase in typhoid fever patients, but rich people don't like me at all. Those who can like me are all poor people. Although they are busy, they don't have much oil and water. Not to mention making money, they also add a lot of medicine money!"

"I think you, a doctor, don't do it anymore. If you go to Lingzhou with me, you can't be able to become a medical officer!" Chen Ying said: "But you also know that there are still risks on the battlefield without any swords and guns!"
