Hearing Cheng Huaimo say this, Li Er walked out of the handsome tent without any hesitation.

"Okay, stop crying, go and see how your father and General Li Shiji are." Zhang Nan said, patted Cheng Huaimo on the shoulder, and then pulled Cheng Huaimo, who was sitting on the ground, and soon, Zhang Nan also brought Cheng Huaimo to the two generals' tents.

As soon as he entered the coach's tent, Zhang Nan saw two generals lying on both sides of the coach's tent. Li Shiji was lying on the left and Cheng Yaojin was lying on the right.

"You tell me, what's wrong with Maogong?" At this time, Li Er's eyes widened, wishing to eat the accompanying military doctor in one bite. Li Shiji was also an old minister who had been following Li Er all the way. In Li Er's heart, Li Shiji's contribution was indelible.

"When I go back to the emperor, General Li has too many wounds on his body. Some of them are already deep and bone-seeking. If the wound is not sutured, the blood will not be stopped at all. Moreover, General Li's wounds are deep. The wounds in the morning have only been bandaged until now. Most of the blood has flowed out. It is really powerless to do anything about it." The military doctor said stumblingly.

"How did you learn in the military academy? Can't you even bandage the wound? Ah?!" Li Er felt very powerless at this time. He might be able to regroup and fight Quan Gai Suwen again, but if Li Shiji was about to die, it would be something that Li Er could not do again.

"Your Majesty, don't be anxious first." Zhang Nan quickly spoke.

Don’t be afraid of deep wounds, just sew the wound up.

"Let me ask you, does General Li's wound hurt blood vessels?" Zhang Nan asked.

"No, I have carefully examined it. General Li's injuries were all trauma, but General Li had already lost too much blood at this time. I'm afraid..." The accompanying military doctor said a few words and probably stopped talking, for fear that Li Er would be unhappy and push him out and chop him.

"I'm afraid, why don't you? Now, you will immediately sew General Li's bleeding wound to me and use this." After saying that, Zhang Nan quickly replaced a set of medical cotton thread and sewed things from the system.

"Go and get a basin of hot water. You must clean the wound before sewing it." Zhang Nan had no choice at this time. Now he has no use except for giving advice. After all, he is not a doctor and cannot help sew the wound.

"Yes, yes, yes." When the military doctor heard Zhang Nan say this, he quickly took the cotton thread and other items handed to him by Zhang Nan and started operating. In fact, the medical courses in the military academy have become relatively mature. Under the leadership of Sun Simiao and the support of Zhang Nan, doctors from military academy are now familiar with some modern simple medical equipment.

The military doctor began to bandage Li Shiji's wound again, while Zhang Nan was watching. At this time, Li Shiji's face was as good as gold paper, and there was no trace of blood on his lips.

"It's not possible to bandage just. If this continues, it's impossible to save us. We need a blood transfusion." Zhang Nan said.

"Blood transfusion? What is blood transfusion?" Li Er asked with a strange look after hearing Zhang Nan's words.

"Your Majesty, think about it, General Li has lost too much blood, so we will kill the blood he lost to him back into his body. Maybe there will be a glimmer of life in this way." Zhang Nan said.

"Then you'll get a blood transfusion, who's your blood? There are so many soldiers in the army, and it's definitely enough to lose a little for Maogong." Li Er said anxiously.

"Your Majesty, don't be anxious. This blood cannot be injected randomly. There are still differences in the types of blood and blood. If different blood are injected, not only will it not be able to save General Li, but it may also directly harm him." Zhang Nan also became distressed when he said this.

Because Zhang Nan didn't know what Li Shiji's blood type was, and Zhang Nan couldn't test it. After thinking about it, Zhang Nan decided to come by himself because Zhang Nan only knew his blood type, which is the O-type blood called selfless blood. Generally speaking, the rejection reaction is much smaller than other blood.

"Is there any military doctor? Come here." Zhang Nan shouted while rolling up her sleeves. Soon another military doctor stood beside Zhang Nan.

"Have you used this?" Zhang Nan said, and then replaced a blood collection device from the system.

"This...no." The military doctor also looked a little embarrassed.

"It's okay if you haven't used it. Now you take this needle and then you will stab me into the blood vessel with one needle later. Remember, push it flat, don't prick it upright, and make sure the needle stays in the blood vessel." Zhang Nan said, then took the rubber tube and stuck it on his arm. Soon, several very obvious blood vessels appeared on the arm.

"Come on, take it easy, don't think so much, you just need to stab the needle in." Zhang Nan said helplessly as he looked at the military doctor who kept trembling with the needle.

It seems that it is necessary to go back and speed up the medical advancement. You can’t go through emergency treatment by just drinking Chinese medicine. Zhang Nan thought in his mind.

Fortunately, the military doctor's mental quality is still OK. Although it was the first time to get a needle, the technique was quite stable. Soon, Zhang Nan's blood flowed into the blood bag. Zhang Nan looked at the number of blood bags. When Zhang Nan was about to stop when he was three hundred cc, he saw Li Shiji's face, Zhang Nan gritted his teeth and stomped his feet, and directly sucked five hundred cc.

After the blood was collected, Zhang Nan took out the needle himself, took a piece of medicine cotton and pressed it on the needle hole and said, "Okay, now follow the same method to stab the needle into General Li's blood vessels."

The military doctor nodded and soon walked to Li Shiji with the blood bag to prepare for a blood transfusion to Li Shiji.

"Qingquan, you've been suffering, but is this method really useful?" Li Er saw that Zhang Nan had finished picking blood and immediately walked over and asked.

"There must be usefulness, but whether you can survive it depends on General Li's own luck. I really have no choice now." Zhang Nan said helplessly. Now Zhang Nan is really exhausted. She has only a system, but she cannot guarantee that she can save people.

"Oh, I hope Maogong can survive." Li Er also said with annoyance.

"It's all my fault. I'm so careless. I think that with hot air balloons and other things, I'll be invincible in the world. This gives the spring Gai Suwen an opportunity." Li Er said, and then smashed his fist on himself.

Li Er was just talking, when Cheng Yaojin, who was lying on the right, started coughing violently. Seeing this, Cheng Huaimu quickly stepped forward, then grabbed Cheng Yaojin's hand and asked with concern: "How are you feeling, Dad?"

It’s just that Cheng Yaojin was in a semi-coma state without anyone asking questions.

"Brother, come and see my father. My father's hands are so hot." Cheng Huaimo held Cheng Yaojin's hand for a while and felt something was wrong.
