Datang: My father is the head bodyguard

When we arrived at the entrance of the military hospital, it was a temporary camp, but very neat.

Li Chengqian put his hands on his hips and looked at the sign at the door. Lu Ruan had been here many times but there was nothing new. Zhao Zhe said hello to Li Chengqian and went to show off his meal.

The two of them walked inside together and passed the medical station. The military doctor lowered his head and wrote something. He didn't even raise his head when he heard the footsteps: "What's wrong? What are the symptoms?"

Li Chengqian looked at Lu Ru'an: "My guy was beaten so hard last night that he fainted and didn't wake up for half an hour. I wanted to come and have a look early this morning."

The military doctor heard that this was no small matter. If the back of the head was hit, it would be fatal.

As soon as he raised his head, he saw Lu Ru'an: "Manager Lu? So this guy got a sap?"

Li Chengqian waved his hand and pointed at Lu Ruan: "He is my buddy, he got a sap."

The military doctor looked left and right, staring at Li Chengqian with a scrutinizing attitude, and even pinched Li Chengqian's face.

"Master? Master's disguise skills are so good? You can't even tell that he's wearing a human skin mask!"

Lu Ruan knew that the military doctor had misunderstood that Li Chengqian was Yuchi Baoqi, so he quickly explained: "This is the current Crown Prince of the Tang Dynasty. Please don't be so rude."

The military doctor was a little embarrassed: "I have seen His Highness the Crown Prince, and I thought, I thought, I'm sorry, Your Highness the Crown Prince."

The military doctor howled at the back, and soon someone came to take Lu Ruan for examination, while Li Chengqian still stood there.

"I wonder if your Royal Highness has anything else to do?"

Li Chengqian nodded: "It's about penicillin."

The military doctor pursed his lips: "I really can't help His Royal Highness with penicillin. It's not even available in Chang'an, let alone in our temporary camp."

Li Chengqian pulled up a chair and sat down: "I'm not asking you for penicillin. Manager Lu and I are preparing penicillin. It's still in the cultivation stage and we need some technical support."

The military doctor was obviously a little shocked: "Have Manager Lu and His Highness the Crown Prince ever learned how to prepare medicines?"

Li Chengqian shook his head: "No, but there is a complete preparation method in the modern medicine chapter, but it is relatively simple. Manager Lu and I are also exploring it now."

The military doctor had obviously read these books: "Can it really be done with that little information?"

Li Chengqian didn't want to get too entangled with this military doctor: "Don't worry about whether it can be done or not. We just can't judge how to test the effect of the prepared penicillin now. Please tell me, is there any way?"

The military doctor thought for a while: "This is actually quite simple. Penicillin is essentially a bactericidal antibiotic. It inhibits the synthesis of mucopeptides in the bacterial cell wall and causes cell wall defects, causing the bacterial cells to rupture and die."

"In other words, you only need to culture a little bacteria, drop the prepared penicillin into the bacterial culture dish, and see if it has a bactericidal effect."

"As for safety issues, the use of penicillin itself requires a skin test. Basically, nothing will happen. However, it is said that there have been cases of death caused by skin tests."

Li Chengqian slapped the table: "I see, the job of cultivating bacteria will be left to you. Manager Lu Ru'an and I can get by with some mold, but it's too difficult to get bacteria that are invisible and intangible."

Military doctor Aba Aba: "No, why did you leave it to me? I also have my own work and life."

Li Chengqian clicked his tongue: "Think about it, if the penicillin is ready, your name will be written on the record. By the way, what is your name?"

"Zhang Chengzhi"

Li Chengqian grabbed Zhang Chengzhi's hand: "Look, Gu's name is almost the same as yours. Think about it, in the record book prepared by Penicillin, there are three words Zhang Chengzhi. Doesn't it mean that the ancestor is honored?"

"If you want to tell me, I have to give you a separate page for your genealogy! If this is true, just tell me!"

Zhang Chengzhi's heart suddenly moved: "Seriously? Then the culture of this bacteria will be taken care of by me, Zhang Chengzhi. After the penicillin is prepared, I can come directly to the military hospital for experiments!"

Li Chengqian smacked his lips: "It would be better if we could provide some more technical support. The main reason is that Manager Lu and I are both very talented. There is a prince and a manager of Baoli Trading Company. What do you think of this technical director Zhang Chengzhi?" Sample?"

Military doctor Zhang Chengzhi's eyes widened: "It sounds so pleasant~ Don't worry, Your Highness, Your Highness, we will definitely put in 120% effort in the preparation and experiment of this penicillin!"

After Li Chengqian got what he needed, he started chatting with Zhang Chengzhi in front of him: "Hey, how long will it take for this inspection, Manager Lu? We have other things to do, so it shouldn't be too late, right?"

Zhang Chengzhi patted his chest and said: "It's not slow, it's not slow. The main reason is that the results are relatively slow. When the time comes, I will take a leave to deliver them to His Highness. I won't bother His Highness the prince about such a small matter."

Li Chengqian chatted with Zhang Chengzhi some more, and Lu Ru'an also came out after the examination and was in a very depressed state of mind.

Li Chengqian went up to support Lu Ruan: "What's wrong? Why are you so depressed during a check-up? Come, let me introduce to you, Zhang Chengzhi, our medical technical director for penicillin preparation."

Lu Ru'an was like a puppet on strings: "I've seen technical director Zhang Chengzhi and Dr. Zhang. During the examination, I was lying down or sitting still. I fell asleep several times. I can't do it anymore. I want to go back to sleep."

Li Chengqian put Lu Ruan's arm around his neck and carried Lu Ruan out of the military hospital. Zhao Zhe had been by the car after dinner, chatting nonsense with the driver.

Zhao Zhe saw Li Chengqian struggling to carry Lu Ru'an, and walked over quickly, easily took Lu Ru'an and put him into the car.

Li Chengqian got in the car: "Go back to Baoli Trading Company. When you get back, you can ask the guy from Baoli Trading Company to get a room for you. I will find you in the car if you want."

The driver responded and continued to focus on driving. After a night of ups and downs, Li Chengqian was feeling a little sleepy.

When they arrived at the entrance of Baoli Commercial Bank, Zhao Zhe and Li Chengqian dragged Lu Ruan inside. Zhao Nanqing was waiting in the lobby and panicked when she saw her brother Ruan coming in sideways.

"What's wrong, what's wrong with brother Ruan? Didn't he go to the military hospital? Why did it become like this?"

Li Chengqian asked the waiter to build a bed with long benches. Lu Ru'an looked at the thin and weak man, why he was so dead when he fell asleep.

Finally putting Lu Ruan down, Li Chengqian rubbed his wrist: "Your brother Ruan is fine. He just felt sleepy all day and night and fell asleep."

Zhao Zhe just couldn't use his strength to get Lu Ruan out of the car, but now he directly picked up Lu Ruan with a princess hug: "Sister, lead the way, we can't let him sleep here."
