For Li Jiancheng, Li Shimin's biggest threat to him is because of his military exploits. Forced by the needs of form, Li Jiancheng could not easily leave Chang'an. The king of Qin could lead his army to the expedition without being involved.

Now Li Jiancheng finally took advantage of Wagang Li Mi and Jiangnan Du Fuwei to ask for an alliance, which attracted the main attention of the imperial court and asked Chen Ying to lead the army to support Lingzhou. Whether Chen Ying can succeed or not, Li Jiancheng must take full responsibility.

If Chen Ying can successfully relieve the siege of Lingzhou, he can also let Li Yuan reduce his dependence on Li Shimin, and Li Jiancheng naturally does not want Chen Ying to have any mistakes. Chen Ying needed armor, Li Jiancheng used his position to meet Chen Ying's needs, Chen Ying needed craftsmen, and Li Jiancheng did not hesitate to meet Chen Ying.

Li Yuan agreed to support Lingzhou at this time, in fact, because Chen Ying invented the duvet suit, because the appearance of the duvet suit can greatly reduce non-combat losses. But now the down quilt in Chang'an City is bought short by the clan gate valve first, which means that Chen Ying will not be able to successfully complete the task.

If you want to talk about the profiteering of down jackets, Li Jiancheng doesn't think so. Although down is not as warm as fine fur, the real aristocracy still disdains to use it, but the high cost is not affordable for the common people. Chang'an's frenzied rush to buy down is also very likely to be instigated by Li Shimin behind the scenes.

The real intention of them to buy down was not to make profits, but to pull Chen Ying's hind legs, and also to intensify the contradiction between Li Jiancheng and the forces of Chang'an Xungui.

Chen Ying is not a disciple of the gate valve, so he naturally doesn't understand the real horror of the gate valve. The family has been married for generations, I have you, you have me, the relationship is intricate, and the so-called killing chickens and monkeys is impossible to talk about. As long as Li Jiancheng dares to raise the knife, it will inevitably make the current situation a mess, no matter who is at fault, Li Jian's CD will be responsible.

Accepting softness and admitting defeat is naturally not Li Jiancheng's character. Li Jiancheng asked Zheng Guanyin to wrap a bed of down futon and personally took it to the mansion of Li Gang, the secretary of the Ministry of Rites and the crown prince Zhan Shi.

Li Gang's concierge is named Li Nianbo, about forty years old, and there is a way that is close to Zhu is red, and close to ink is black. After studying with Li Gang for more than ten years, although Li Nianbo is just a porter of Li Gang, he is a very learned person, and he is especially good at scripture and righteous articles.

When Li Nianbo saw Li Jiancheng, he hurriedly bowed and saluted, "Bow down and meet His Royal Highness the Prince!" ”

"After the end of the school, Li Jiancheng will ask to see the senior teacher Mr. Wenji......" Li Jiancheng respectfully saluted outside Li Gang's mansion with the gate closed.

However, Li Jiancheng's title to Li Gang startled Li Nianbo. It doesn't matter if you call your predecessor Mr., how can this ancestor be called casually? For thousands of years, there are only two people who are qualified to be called the first teacher, Confucius and Yanzi, and now Li Jiancheng calls Li Gang the first master as soon as he comes up, as a veteran who has respected Confucianism all his life, Li Nianbo feels a little unacceptable.

However, Li Jiancheng obviously has no ideological baggage in this regard, and he respectfully respects the Hou outside the door, really as if a pious disciple is visiting the Confucian master.

Li Nianbo shook his head, returned to the inner courtyard to meet Li Gang, and conveyed Li Jiancheng's words to Li Gang's ears word for word. Li Gang sighed slowly: "If you are courteous, you must ask for something, it seems that His Royal Highness the Crown Prince is not in trouble!" ”

Li Gang was a famous minister at the end of the Sui Dynasty, and served as the master of the three princes of the Sui and Tang dynasties. Don't look at Li Jiancheng as the crown prince, in front of Li Gang, he is still a student.

Li Jiancheng saluted Li Gang respectfully with a pious face: "After the end of school, I will go to meet my predecessor, Mr. Wenji!" ”

"The ancestor can't afford it!" Li Gang said: "It seems that the plan is not small to make His Royal Highness the Crown Prince condescend to his dignity!" ”

Li Jiancheng's face was not red, and he said angrily: "Mr. Wenji is a general knowledge, and he is a master of history, if Mr. Chengji deserves the title of a teacher, I would like to ask who in this world deserves it!" ”

There is a way that everyone carries a sedan chair, although Li Gang is not good at money, but he loves to be famous. Li Gang stiffened his face and said: "His Royal Highness the Crown Prince should not be like this, trying to make people laugh!" ”

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

Li Jiancheng smiled slightly, knowing it in his chest. So he told Li Gang about the fact that the gate valve of the Chang'an family robbed the down for personal gain.

After listening to Li Jiancheng's words, Li Gang took the case: "It should be killed, it really should be killed, the Tang Dynasty is now an eventful autumn, and the gentry have the responsibility of stabilizing the country. ”

Although Li Gang is only a secretary of the Tang Dynasty, Li Gang's reputation is excellent, and even Kong Yingda is not as prestigious as Li Gang. In the court, Li Gang represents Qingliu, and this group of Qingliu doesn't matter what kind of gate valve you are or what family background you have, you will be impeached to death if you are caught.

Li Jiancheng invited Li Gang out, but obviously the court will definitely be lively.

Medical officers are also used in the Tang Army, but the number is very small, almost more than 12,500 people in each army are equipped with one military medical officer, and the generals who attach importance to the medical treatment of the military camp may also add two more to the military medical officer. In peacetime, it is barely enough to treat a headache and foot pain, but when there are a large number of casualties in wartime, this amount of manpower is not enough at all.

In fierce battles, there are always a small number of people who die on the spot, and most of them die from blood loss or infection after injury, resulting in a large number of attrition. There are many factors that affect the morale of the soldiers, and the lack of timely and effective medical treatment for the injured is not the most important thing, and it cannot be ignored.

Of course, the profession of doctor has high requirements for practitioners, and the training time is long, and those who have the ability to train their children to be literate for a long time are keen on fame, although the profession of doctor is also respected, but after all, it is not classified into the category of the gentry, which also causes the scarcity of doctors in the world.

After Chen Ying returned to the mansion, he summoned Chen Huairen. Chen Huairen was originally a bruiser, and in the Battle of Jingyang, he learned the skills of diagnosing and treating external injuries from Chen Ying for a while, but now the wounded in the Tang army are not Chen Huairen's turn to take action. In order to make a living, Chen Huairen had to open a small pharmacy in Chang'an City.

Chen Ying looked at Chen Huairen and asked, "Huairen, I haven't asked for a while, how is your pharmacy now?" ”

"Don't get it!" Chen Huairen said with a depressed face: "Since the beginning of winter, the number of typhoid fever patients has increased greatly, but the rich people don't look down on me at all, and those who can look down on me are all poor ghosts, although they are not less busy, but there is no oil and water, let alone making money, and a lot of medicine money is pasted in!" ”

"I see that you have done a good job, come with me to Lingzhou, and if you don't keep it, you can mix with a medical officer!" Chen Yingdao: "However, you also know that there are no eyes on the battlefield, and there are still risks!" ”

"People die for money, birds die for food!" Chen Huairen said: "Seek wealth and danger!"
