Datang: My father is the head bodyguard

Li Chengqian stood in front of the telegraph machine with his hands behind his back, while Lu Ruan was operating it.

"I want hundreds of tons of polished rice and flour, as well as as many oranges and citrons as I want. Send them to Liangzhou City immediately, as fast as possible!"

Lu Ruan hit the send button with excitement, and Changan soon responded.

"receive."

Li Chengqian began to analyze with Lu Ruan why they always failed. Lu Ruan shook his head: "It was all according to the records in the book. Two times, 20,000 groups, the entire army was wiped out."

Li Chengqian held the book on modern medicine in his hand and looked through it carefully, trying to find some clues.

Seeing Li Chengqian's serious and focused look, Lu Ruan couldn't bear to tell him: "Your Highness, we followed the book step by step, but we just can't..."

Li Chengqian suddenly interrupted Lu Ru'an: "Growing up in the imperial city, I rarely saw moldy food except once. The citrons I picked from the imperial grandfather's courtyard were put from summer to autumn, and finally they were full of mold. Green mold.”

Lu Ru'an didn't know what Li Chengqian meant, so she just listened quietly to Li Chengqian's continued words.

Li Chengqian felt that he was about to catch that spiritual light, and he thought about it carefully.

"I recall that in the summer, I didn't find any mold with green hairs. It was just that the whole citron shrank and lost a lot of water, and it was only in autumn that the hairs grew. By the way! A few days before the hairs grew, It’s been raining for several days!”

Lu Ruan frowned: "Your Highness, you mean that the growth of mold can be artificially controlled?"

Li Chengqian nodded and then denied: "It's not about controlling growth, but about controlling the conditions for growth!"

Li Chengqian suddenly understood something and rushed directly into the glass laboratory in the backyard, where there were guys cleaning experimental equipment.

As soon as Li Chengqian walked into the laboratory, he knew that he had probably found the problem. Li Chengqian shouted to Lu Ru'an excitedly.

"It's too dry! It's too dry! The temperature is wrong, too low!"

Li Chengqian rushed out of the glass laboratory and grabbed Lu Ruan's hand: "Quickly, find three or five steamed buns. Let's try the temperature and humidity required by the mold. It must be! This must be the reason!"

Lu Ru'an was also infected by Li Chengqian's passion and quickly gave orders, and soon freshly baked buns and rice cakes were delivered.

Li Chengqian asked Lu Ruan to prepare several separate rooms for cultivating mold, and Li Chengqian explained to Lu Ruan.

"We don't know the specific temperature and humidity required by mold now, so we can only try it over and over again. Your Baoli Trading Company should have a thermometer, right? How do you measure the humidity?"

Lu Ru'an had an idea: "Isn't there a sauna in the bathhouse? Is there something like this in the sauna? It was shipped here together, so it should be installed, right?"

After Li Chengqian heard this, he immediately pulled Lu Ru'an and left. Lu Ru'an gave directions as he ran. Since this was the first batch of supporting equipment for Baoli Trading Company in Liangzhou City, the location was chosen better, not far away.

Lu Ru'an was greeted by waiters as soon as she entered the bathing center. Lu Ru'an ignored them and followed Li Chengqian straight to the men's area sauna.

"Steward! Hey! Steward..."

Lu Ru'an and Li Chengqian worked very quickly. They pulled off all the thermometers and hygrometers hanging in the sauna. They ignored the waiter and rushed to Baoli Trading Company with two items.

Li Chengqian walked to the door and thought about something wrong: "How do we control the temperature and humidity? Go back! Get the volcanic stone and charcoal stove in the sauna!"

Lu Ruan grabbed Li Chengqian this time: "If someone sends it over, we probably won't be able to move it!"

After Lu Ruan finished speaking, he called directly to the clerk who had just greeted him: "Go find someone and move the volcanic stones in the sauna to the trading house. Are there any spare volcanic stones and charcoal stoves?"

The guy thought for a while and said, "There seem to be four or five spare sets in the warehouse. Can you bring them over too?"

Lu Ruan nodded: "Bring it! In addition, if there are spares of these two things in the warehouse, you can also get them. These are fragile, so you have to be careful!"

After saying that, Lu Ruan directly took Li Chengqian to the trading house. Li Chengqian started to think about it again, thinking as he ran.

"Ruan, do you think the humidity of the food itself will also have an impact? The citron I had before has spent a whole summer, so it probably doesn't have any moisture."

Lu Ruan scratched her head: "How to do it? Bake those foods? Isn't that possible?"

Li Chengqian frowned: "In this way, we will do it in groups, and we will do both the roasted and non-roasted ones. We will do a small-scale experiment first, and then wait for the Gu Dong Palace supplies to arrive, and then do a large-scale experiment!"

Lu Ruan nodded solemnly: "If it is done, I will probably end my training as a steward of Baoli Trading Company ahead of time."

Li Chengqian hooked Lu Ruan's shoulder: "Come to the East Palace to help the orphans. The British prince went to sea a few days ago and is not in Chang'an."

The two started the experiment step by step, and everything from the bathing center was delivered. Li Chengqian first set up a charcoal stove in a room and connected the ventilation ducts to prevent charcoal poisoning.

"No, no, it's too hot. Although that autumn was a bit annoying, it wasn't to this point of burning."

Lu Ruan and his assistant used tongs to take out a few pieces of charcoal from the charcoal stove, and then poured a ladle of water on the volcanic rocks.

Li Chengqian closed his eyes and felt: "It's not wet enough, then splash it again. I remember it was an autumn day, and it rained for many days in a row, so splash it again."

As Lu Ruan splashed water more frequently, the humidity in the entire room quickly reached over eighty. Lu Ruan leaned against the charcoal stove, and with the added humidity, his whole body was as if he had been fished out of the water.

Li Chengqian closed his eyes and suddenly shouted: "Almost! This is how it feels!"

Lu Ruan looked at the hygrometer and saw that the red pointer stopped at eighty-five.

Li Chengqian felt the temperature: "I think the temperature is about the same, but people need to look at the stove and hygrometer to maintain this feeling at all times."

The guy on the side took off his clothes directly: "It's a little hot without clothes, I'll do it! If you get wet, get it wet, I'm afraid of getting hammered!"

Soon, the shelves in the room were filled with steamed buns and rice cakes spread on gauze. On the other side were baked steamed buns and rice cakes, even a little crispy.

Li Chengqian and Lu Ruan were sitting outside the room, standing up from time to time to check the temperature and humidity, and to check on the workers to avoid fainting from the heat.

Soon, Li Chengqian, who had not slept much, fell asleep on the table. Lu Ru'an took off his clothes and covered Li Chengqian's body, while he was always paying attention to the situation in the room.

Lu Ru'an murmured to herself: "I'm afraid I've had a hard time these days."
