Datang: My father is the head bodyguard

Li Chengqian pondered for a moment: "This request cannot be promised to Mrs. She. The Tianwei Army is subordinate to the father and is led by the British Duke. It cannot be interfered by a single prince."

Mrs. She looked at Li Chengqian for a long time: "His Royal Highness, you can readily agree. Whether I will survive until that time is still unknown."

Li Chengqian laughed: "I just listened to Uncle Lu's three words. How do you teach Gao Ming to make random nonsense and make nonsense promises? If you can do it, speak it naturally. If you can't do it, you can't make promises."

Mrs. She waved to Lu Ruan: "An'an, are you really willing to marry Qing'er as your wife?"

Lu Ru'an walked to Mrs. She and knelt down in front of her: "Grandma, my grandson's intention to marry Qing'er is sincere. Ru An is willing to abide by the Lu family's ancestral precepts."

Mrs. She showed a rare kind look and gently stroked her hand over Lu Ru'an's head: "Go and call Qing'er."

Li Chengqian thought that this old lady was quite easy to talk to.

Zhao Nanqing arrived, and Shangguanshi was by her side. Mrs. She looked at Zhao Nanqing: "Qing'er, Ru An wants to marry you, are you willing?"

Zhao Nanqing couldn't hide her excitement: "Qing'er is willing! Wherever brother Ru An is, Qing'er will be there!"

Madam She cast a sidelong glance at Lu Ru'an: "You brat, I'm really taking advantage of you. My dear Qing'er, come here and ask grandma to take a good look at you. I haven't come back to take a look at you even after being away from home for three years."

Mrs. She changed the subject: "When did Qing'er recognize His Highness as her godbrother?"

Li Chengqian's eyes were calm and he held the tea bowl nonchalantly: "It is destined that Zhao Zhe recommended himself to be Gu's subordinate. Then Qing'er is naturally Gu's god-sister. When he returns to Chang'an, Gu will ask his father to issue an imperial edict. Sister Shi Qing'er has a title."

Zhao Nanqing covered her mouth, in disbelief, she had become Li Chengqian's god-sister, a princess?

Li Chengqian put the tea cup on the table: "When the disaster relief here is over, Gu will go directly to Lingnan to develop Lingnan. If Ru An wants to go with Gu, the marriage must be done as soon as possible."

Mrs. She and Lu Feng both frowned secretly: "Well, is the journey to Lingnan too far? Ru An and Qing'er are not strong, so what if something happens on the way?"

Li Chengqian was happy: "You two elders should go out and see more. Now it is very convenient to take a train from Ganzhou City to Chang'an and then transfer to Lingnan by bus."

"The new head of the Li family in Longxi, Li Feng, is a man from Lingnan County. He has been presiding over the road construction in Lingnan. It is no longer the same as before."

Everyone chatted about Lingnan affairs, and Zhao Zhe was pulled by Li Chengqian to chat with Lu Feng about betrothal gifts and dowry, and a date was set.

After lunch, Li Chengqian wanted to go to the military hospital to ask Zhang Chengzhi, so they all went directly together.

When he arrived at the military hospital, Li Chengqian directly asked Zhang Chengzhi where his camp was and went straight to the topic.

Across the glass, Zhang Chengzhi was fully armed and doing experiments with a dropper in his hand. Li Chengqian probably had to disinfect the inside before entering, so he might as well wait outside.

Li Chengqian saw Zhang Chengzhi put down the dropper in his hand, and Li Chengqian knocked on the glass window with his hand. Zhang Chengzhi turned around and saw Li Chengqian. He first took off all his clothes, and then came out to see Li Chengqian.

"Your Highness, Manager Lu and Brother Zhao Zhe came to deliver penicillin yesterday. I learned about the method you used to cultivate mold, and I also used it to cultivate some bacteria."

"It grows and divides faster. Now there are enough bacterial petri dishes to test penicillin. I have just completed all the operations. It will take a while to take effect."

Li Chengqian and Lu Ru'an nodded, and Li Chengqian was the first to speak: "How certain do you think you can succeed?"

Zhang Chengzhi poured cold water on it: "The Governor once said that penicillin prepared by local methods is difficult to be effective. Even if it is effective, it may have too many impurities. If a method can be found to crystallize and purify it, it might be effective."

"It's just...it's just that His Highness the Crown Prince and Manager Lu sent us liquids. Thinking about it... we can't have too much hope."

Lu Ruan patted Li Chengqian on the shoulder: "Step by step..."

Li Chengqian let out a long sigh: "I know, I understand. It's just the crystallization method Xiaobao mentioned, how to do it? Do you have any idea?"

Lu Ruan was relieved to see that Li Chengqian was not discouraged, but Li Chengqian's question made Lu Ruan's scalp numb again.

"There should be corresponding subjects in the books sent, but I don't know which one it is in. How about going back and looking through it?"

Li Chengqian nodded: "Okay, after the results of Chengzhi come out, we will find someone to send them to Baoli Trading Company. We will go back first."

Zhang Chengzhi saluted Li Chengqian and Lu Ruan: "No problem, I will send it directly as soon as the results come out, and I will take a look at your mold cultivation laboratory to see if there is anything that can be improved."

Lu Ru'an and Li Chengqian were waiting at the edge of the camp for Zhao Nanqing to finish his physical examination. Zhao Zhe went to look for food again, and didn't eat much in Lu Mansion.

Zhao Nanqing came out with the physical examination report, and Lu Ruan walked over quickly: "How are you? Is there anything wrong with your body?"

Zhao Nanqing handed the report to Lu Ru'an: "No, they are all above normal. The female military doctor told me that she is in rare good health."

Lu Ruan held Zhao Nanqing's hand: "As long as you are healthy, let's go back."

Zhao Nanqing blessed Li Chengqian: "Thank you, Your Highness, for asking for this marriage for my little girl."

Li Chengqian put his hands behind his back: "Ahem, call me brother. Ruan, you are my brother-in-law. My brother-in-law is very capable, so you have to work hard."

The four of them returned to Baoli Trading Company. Zhao Nanqing went directly to cook. Zhao Zhe, Li Chengqian, and Lu Ruan looked at the pile of books on the counter.

"Come on everyone, let's read it all~, the key word is crystallization, let's read it one by one."

A stack of books per person, a table per person, and a manual search began. They looked at it for two hours until Zhao Nanqing called the waiter to come over and serve the food.

Li Chengqian rubbed the bridge of his nose: "Hey, have you found it? Are the three of us too short of manpower? Are the guys literate? Those who are literate can add money and look for it together."

Lu Ruan sighed: "I found the crystal. When I saw the title of the book, Refining with Coarse Salt, I found it was pure white dry matter."

Zhao Zhe held on to the table: "I can't stand it anymore. I can't stand it anymore. These words are spinning. Am I going to vomit? vomit~"

The big round table in the hall was filled with food by the waiters. Zhao Nanqing walked out wearing an apron embroidered with a little raccoon slave: "Don't look at it now. Let's eat first. All of you are so excited."

Li Chengqian stood up and stretched: "Eat! I have never looked forward to eating so much!"
