Datang: My father is the head bodyguard

Li Chengqian and Lu Ru'an waited day after day in Baoli Trading Company in Liangzhou City. Li Chengqian stayed vigil at night and Lu Ru'an stayed during the day.

The two of them only meet for almost an hour and a half every day, which is during dinner time in the evening.

Li Chengqian had just woken up and was rubbing his sleepy eyes. He didn't know what to hold with the chopsticks in his hand. Lu Ru'an saw that Li Chengqian had a poor appetite, so he asked the waiter to mix a sweet and sour cold dish.

Li Chengqian yawned: "Ruan, it's been three days. Is there something wrong with our method?"

Lu Ru'an didn't know either: "I don't rule out this possibility, just wait and see."

After a while, the waiter brought a bowl of cold skin mixed with sour radish and pickles. The top was covered with minced garlic, which must have been stirred with hot oil. The garlic was full of fragrance, which whetted Li Chengqian's appetite.

Li Chengqian held the bowl, mixed the whole cold skin with chopsticks, and put it into his mouth with big mouthfuls, making "ummm" sounds while eating.

Lu Ruan was afraid that Li Chengqian would eat too fast and choke. He raised his hand to lift the teapot, poured a cup of warm tea for Li Chengqian and placed it in front of Li Chengqian.

Lu Ruan was much more polite when eating. This was also because he was about to change his shift and could go to rest. He slowly ate the food on the table.

It can't be said to be rich. The two vegetarian dishes were fried in meat oil, which was regarded as meaty.

The supplies delivered by Li Chengqian's East Palace arrived yesterday, and nearly half of them were distributed to the victims in the city. However, they didn't know how much they would need for the experiment, so they had to use sparingly.

Li Chengqian finished half a bowl of cold skin and choked on eating too quickly. He happened to see the tea in front of him, picked it up and poured it into his mouth.

"Ha~ This is the most appetizing thing I have ever eaten in Liangzhou. It's really good."

Lu Ruan narrowed her eyes and smiled: "His Royal Highness likes it, just ask the chef to make more."

Li Chengqian drank a few sips of tea, choked on the food, picked up the bowl and continued eating. This time he didn't gobble as much as before, but he recalled some palace etiquette.

"Oh!"

Lu Ru'an and Li Chengqian both looked back at the place where the sound came from, and saw a shirtless guy. Even though he was tired, he couldn't hide the excitement on his face.

"Moldy!"

The gentle Lu Ru'an and Li Chengqian, who had just regained the etiquette in the palace, rushed over like wild dogs on the loose, pulled away the waiter, and went directly to the room.

Lu Ru'an checked the shelves one by one and the food one by one, and shouted to Li Chengqian: "It's all there, it's all there!"

Li Chengqian was watching from the drying area: "The dried ones are also moldy, but there are a few specks, not too many. Then there is no need for another step of drying, just put it directly into the mold room."

Li Chengqian and Lu Ru'an went to check different areas respectively, and even the voices of their conversations highlighted their excitement.

Soon, Lu Ruan realized that something was wrong: "Your Highness, we need to get out quickly. The smell here..."

Li Chengqian took a sniff and said: "The smell of corruption is too much. I asked the guy who came to see the stove to wear a mask, and he had to change it every half an hour. How many masks are there?"

Lu Ruan nodded: "More, this is not a big problem."

The two walked out of the room, and good news came from the remaining rooms one after another. Li Chengqian looked at Lu Ru'an.

"It's time to adjust the temperature and humidity in the glass laboratory. I feel like we will make it this time!"

Lu Ru'an was still a young man after all. He couldn't hide his excitement for a moment. He clenched his left fist and raised it high: "It will happen!"

Li Chengqian stood outside the glass room, watching the busy workers inside, while Lu Ru'an arranged the petri dishes and other processes.

Fortunately, after accumulating experience from the two previous failures, the guys all knew what the supervisor asked them to do. Soon, nearly 10,000 sterilized petri dishes would be transported to the laboratory.

Li Chengqian quickly shouted to stop: "First make a hundred, try making a hundred."

Lu Ruan thought for a while: "Listen to His Highness the Crown Prince, conduct small-scale experiments, and then mass-produce it if it succeeds."

After everything was ready, Li Chengqian and Lu Ru'an wore masks, disinfected their entire bodies and walked into the mold room together. Li Chengqian wanted to make it himself.

Li Chengqian was holding a small scraper, and Lu Ru'an was standing in front of a moldy steamed bun, while Lu Ru'an was holding a petri dish to collect the mold.

Li Chengqian was a little nervous, the hand holding the scraper was shaking slightly, and his gloved palms were already full of sweat.

With a gentle scraper on his hand, the mold on the steamed bun fell into the petri dish. Lu Ruan quickly closed the lid and took another one from the cart nearby.

The two of them worked together to store all the mold on the rotten food in the first mold room into petri dishes, marking each one with time and number.

Originally, the temperature and humidity in the mold room were relatively high, and due to the nervousness, after doing this, Lu Ru'an and Li Chengqian felt as if they had been fished out of the water.

The two people came out of the mold room and breathed a sigh of relief. Lu Ru'an and Li Chengqian pushed the cart towards the glass room laboratory.

As soon as Li Chengqian entered the laboratory, he felt the familiar feeling of boredom and frustration, which was basically the same as in the moldy room.

The two of them placed a hundred petri dishes and settled them down. Li Chengqian and Lu Ruan called the waiters over.

"The laboratory requires sterility, full body disinfection, and full armor before entering. Let's divide the shifts into four. Each person will be given three hours, and a high temperature allowance will be provided."

Lu Ruan nodded: "Add another shift to be on call at any time. If there is an emergency, someone can be substituted temporarily."

Li Chengqian thought for a while: "Before, we focused on cultivating mold. To put it bluntly, this is the first step. What about the next steps?"

Lu Ruan clicked her tongue: "Let's go back and read the records in the books first. Prepare all the necessary things and take a look step by step!"

Li Chengqian nodded: "You should go back and rest first, and come and study alone."

Lu Ruan refused directly: "I'm in high spirits and can't sleep! Let's go together."

The two of them returned to the lobby of Baoli Trading Company, took off their fully equipped outfits, and held the books together to examine them carefully.

"Funnel, cotton and gauze filter, do you have a glass jar?"

Li Chengqian slapped his forehead: "Look at the question I asked. Aren't canned fruit jars everywhere?"

Lu Ruan looked at the subsequent process: "Acid water, kelp water, it says vinegar can be used to make acid water. Is this kelp water made from dried kelp?"

Li Chengqian carefully checked the kelp water part and found a line of small words that read: "Details are noted on page 131."

Li Chengqian quickly turned to page 131. The kelp water acts as alkaline water and precipitates the penicillin in the charcoal powder.

"Alkaline, alkaline, alkaline? Alkaline!"
