Li Shimin waved his hand and said with a smile on his face: "Du Chengfeng, you don't have to be polite." I'm very happy that you can take the initiative to come and see me. Can you tell me what you are doing today? ”

Li Shimin's tone was sincere and cordial, and Corporal Lixian's attitude was vividly expressed in Li Shimin because of Du Chengfeng.

Li Shimin's attitude can be said to have stunned the eyes of the officials below. In their impressions, there has never been a non-governmental person who can make Li Shimin lower his stature so much.

Ignoring the discussions of the officials below, Du Chengfeng just looked at Li Shimin intently, and said calmly: "Your Majesty, the kid is here today just to offer a treasure. A treasure that can benefit the people of the world. ”

"A treasure that benefits the world?" Li Shimin's mouth opened wide, and his eyes lit up, "Du Chengfeng, quickly present it to me." ”

"Your Majesty, in order to convince everyone, please allow the kid to demonstrate it for everyone, the process may be a little uncomfortable, and please forgive the emperor." Du Chengfeng continued to say flatly.

"You can demonstrate at ease, I'll watch from above." Li Shimin said disapprehantly.

"Good!" After obtaining Li Shimin's consent, Du Chengfeng rolled his left sleeve to his shoulder little by little in full view of everyone, and then quickly took out a shiny dagger from his sleeve robe under everyone's unknown gaze.

Before everyone could react, he quickly slashed his left upper arm, and then quickly retracted the dagger into his robe.

Du Chengfeng did not hesitate at all with this knife, he was quick and ruthless, and his face did not change after the stroke, and he was calm and calm.

After the stroke, Du Chengfeng's left arm was already full of blood, and it soon got wet on the floor of the Taiji Hall.

A speech official saw Du Chengfeng take out a dagger in the Taiji Hall fairly, although it was he who scratched himself, but he was still suspected of despising the imperial power, so he quickly stood up and said seriously: "Emperor Qibing, this Du Chengfeng ......"

It's just that before he finished speaking, he was interrupted by Li Shimin's stern reprimand, "Shut up and retreat." ”

In fact, at the moment when Du Chengfeng took out a dagger and scratched himself, Li Shimin did not have the slightest doubt in his heart, and his face was colorless, only calm. He stared at Du Chengfeng's next move intently.

Du Chengfeng's bold move also stunned the generals on the side. Such as Cheng Yanjin, Qin Qiong, Li Jing, Li Xiaogong and others.

Li Xiaogong is a person who has dealt with Du Chengfeng several times, and he only knew that Du Chengfeng was a genius before. Now I'm afraid I'm going to add another layer of definition to Du Chengfeng.

"This kid is a ruthless man! A knife goes down, and the face does not change color. Cheng Yanjin said on the side.

"I'm curious what this kid is going to do next?" Qin Qiong looked and said.

The civil and military officials in the hall were also very curious about what Du Chengfeng was going to do next.

At this time, Du Chengfeng first took out a small half bottle of wine from his arms and poured it on the bleeding wound, rinsed it, and then took out the white medicine processed last night from his arms.

Of course, this bottle of white medicine was specially made by Du Chengfeng, and the effect was stronger than the one that saved Liu Chun yesterday.

When Du Chengfeng sprinkled the prepared white medicine powder on the wound little by little, the blood at the wound almost stopped and coagulated little by little at a speed visible to the naked eye. The bleeding from the wound was stopped between a few breaths.

Hiss! The generals almost gasped. All of them have exaggerated expressions. Although he didn't speak, his inner desire undoubtedly didn't need to be explained, and the expression on his face was a good explanation.

The wound that Du Chengfeng drew with a dagger is a relatively long and deep wound. And even if the wound is long and deep, as long as the white medicine is sprinkled after disinfection at the first time, the wound can quickly stop bleeding and coagulation.

In other words, if this medicine is used in the army, no matter how much knife wound or the like is disinfected and supplemented with this white medicine, then the possibility of infection and suppuration can be completely eliminated.

Not only that, but the time for the wound to heal will also be several times faster. What's more, the efficacy of this white medicine is not only for the treatment of trauma.

Some of the civil servants present may not have been aware of the importance of this white medicine. However, Li Shimin and a group of generals who had fought from the battlefield instantly straightened their eyes and their eyes were red, and they couldn't wait to immediately snatch the medicinal powder in Du Chengfeng's hand and study it.

It's just that the parties Du Chengfeng and Li Shimin didn't speak at this time, so they naturally didn't dare to make a mistake casually. But that doesn't mean they don't know the magic of this powder.

The hemostatic effect of this medicine powder no longer needs to be explained, and Du Chengfeng's wound cannot be faked.

After demonstrating the effect of hemostasis, Du Chengfeng did not put down his sleeves, and after a while, he had to show the healing of the wound to everyone to watch.

"Du Chengfeng, is this the treasure you want to offer to me?" Before Du Chengfeng could explain, Li Shimin's breathing had become rapid.

"Exactly! I believe that the emperor and all the adults have seen it very clearly. Du Chengfeng said loudly.

"Quick...... Tell me more about what this does. Li Shimin's heart beat faster, and his lips trembled.

"Okay." Du Chengfeng responded, and then took out a bottle of granular white medicine from his arms, but it was temporarily in a porcelain bottle. In order to distinguish it, Du Chengfeng named this powder as Baiyao, and the granular one as Baibaodan. Baiyao is used for external application, and Baibaodan is used for internal use.

Du Chengfeng took the white medicine and Baibaodan together in his hand, and said slowly: "Your Majesty, there are two kinds of treasures, please allow me to explain them in detail." ”

"I'll call this powder a white medicine for the time being." Du Chengfeng picked up the powdered white medicine and said: "I believe that its hemostatic effect can be seen clearly by the emperor and all the adults just now." Its main effect is to stop bleeding and remove stasis, invigorate blood and relieve pain, detoxify and reduce swelling and accelerate wound healing. It can be used to completely eliminate purulent infection caused by knife wounds or other wounds. A general knife wound can heal in just a few days, and a normal fall or something has a faster effect. And this medicine contains one life-saving pill in each bottle. If it is a serious injury, dying or serious internal injury, taking this life-saving pill can save your life to a large extent and buy more time for treatment. ”

By the time Du Chengfeng finished explaining the efficacy of the white medicine, the generals in the hall were already restless.

"Your Majesty, this is a sacred object! If it is equipped in the army, then our soldiers will not sacrifice so much for no reason. When I think of those brothers who died because of their injuries, I ...... old Cheng" Cheng Yanjin couldn't stop the excitement in his heart, and said anxiously.

As he spoke, he was still a little touched, and it looked like tears were about to flow out.

"Haha! Big black, you're pretending to be a little too much! Wei Chi Jingde, who was on the side, couldn't get used to Cheng Biting Jin's sad and sad look, and teased.
