He was even more uncomplaining, crawling on the ground, not daring to move, and his whole body was trembling like a sieve.

Tears welled up in Bai Chun's eyes from time to time. This was the first time in all these years that the prince was so angry with her. She knew she was wrong, but for some reason, she always felt aggrieved.

After being stunned for a long time, he finally turned around and decided to continue following the crowd towards the last restricted area, the "medicinal food room".

The inspection in the herbal medicine room was extremely strict. Even Li Hong had to take off all metal objects on his body, not to mention other things.

No one is allowed to bring in silk items, and even hair needs to be tied up before passing.

Fortunately, Xia Zhi and others today were all wearing pure cotton shirts and skirts like Bai Chun. Li Hong and his party had made sufficient preparations before coming.

And she has been so fair and pure for so many years, always wearing a white cotton shirt and dress, and she doesn't wear her hair in a bun because of the existence of the "medicinal food room". Dressing like this, it is naturally much more convenient for her to go in and out.

Gunpowder is naturally the top priority of the medicinal kitchen, but black powder is only one of them, and yellow explosive is the top secret matter, but there has been no way to make much progress.

In his previous life, Li Hong knew that yellow dynamite was the most stable of all explosives, and only this kind of explosive could become the most reliable one in this era of extreme lack of production safety.

...

...

Picric acid is another kind of explosive, which is extremely unstable. Li Hong now only allows a very small number of people to slowly explore the natural caves in Taiyi City. It is unknown whose idea it was, but they actually combined nitric acid and sulfuric acid to process glycerin, and thus a yellow transparent liquid appeared, namely nitroglycerin.

Sun Simiao also knew the formula of gunpowder at this time. In his "Sun Zhenren Dan Jing", he recorded the formula of gunpowder: "Sulfur, saltpeter, and soapberry are burned together in the sulfur fire method."

Everyone who enters the "medicinal food room" will be covered tightly. As the glass technology becomes more and more sophisticated, glasses to protect the eyes naturally came into being.

Each person is wearing goggles, thick masks, gloves, etc. In short, the only thing that is exposed outside is the pair of eyes under the goggles.

The "medicinal food room" with more than one hundred people occupies a very large area, that is, those caves. Most of them belong to the "medicinal food room", and Wufawutian is one of the persons in charge.

A walk around the "medicinal food room" made Xia Zhi and the others feel like they had walked through the gates of hell. The prince, who never took rules seriously, was unusually cautious in his actions in the "medicinal food room", and was extremely careful even when touching black, yellow, or other things.

But this was also the first time they discovered another side of the prince. When communicating with the craftsmen in the "medicinal kitchen", it seemed as if a real man appeared before their eyes: serious and focused.

Looking at those clear eyes, I couldn't help but feel moved, as if my heart was firmly connected to the prince.

Everyone was sweating profusely when they came out. There was no other way. Although the cave was cool and dry, it was not enough to withstand the thick cotton clothes and full armor.

After coming out, Li Hong didn't say anything. He got on the carriage directly and just said lightly: "Go back home."

As for Bai Chun, Li Hong had no interest in even looking at her. At this moment, he was still feeling angry.

Is this really the tradition of the Chinese nation? Why would someone unconsciously lower the standard? Bai Chun was not unaware of all the pros and cons, but why did she dare to hide it from me and sell the defective glass to the merchant!

Everyone knows that speculation and selling inferior goods as good ones can bring temporary profits, but Bai Chun doesn't know the disadvantages of doing so?

Bai Chun looked lonely and was the last one to get on the carriage. The hardworking people followed behind the carriage, one man and one horse. No one knew how the prince would punish them next.

Since getting on the car, Xia Zhi and the others have become cautious, not as relaxed as when they came. They seldom see the prince angry once a year, and they can't even remember the last time the prince was angry.

Cheetah and the others were better off. After all, the four of them were outside the carriage, so they naturally felt less depressed by the depressing atmosphere in the carriage.

Li Hong leaned against the window of the carriage, not saying anything, just quietly looking at the scenery outside and thinking about his own thoughts. He naturally knew the people in the carriage, and if he was in a bad mood, they would not be in a good mood either.

But Bai Chun must learn a lesson from this incident, otherwise who knows what will happen in the future.

"Master, Bai Chun admits his guilt. Please punish me." Bai Chun said with fear and grievance in his tone.

"You still know you're wrong? I've been handing Taiyi City over to you with confidence over the past few years, but what have you done? Don't you know that the reputation of our Taiyi City is more valuable than those copper coins at this time? Now you're the only one in the market, you've monopolized the market, but when this Chamber of Commerce is over, merchants from both the north and the south will be able to make this glass, what can you use to compete with them?"

Bai Chun's words completely ignited the powder keg. Li Hong looked at Bai Chun kneeling in the carriage and continued coldly: "When the merchants no longer trust you, even if you lower the price, you can't restore your lost reputation! At any time, you must always remember that quality is your only foundation. If you lose this belief, sooner or later you will lose all the merchants in Taiyi City! At that time, what can you use to restore Taiyi City's reputation? Speak!"

The more he spoke, the angrier he became. At the end, looking at Bai Chun who was kneeling there with his head down and keeping silent, Li Hong couldn't help but slap the table in the carriage in anger. With a bang, the tea set and other things on the table vibrated.

The five people in the carriage were so frightened that they couldn't help but tremble. The tea on the table was knocked over and spilled everywhere, but no one dared to clean it up. They just knelt in the carriage trembling with fear, silently and motionless.

The carriage slowly drove into the manor. The weather above seemed to be in line with Li Hong's mood. The overcast sky began to slowly drop raindrops as big as beans.

"Reflect on yourself. You are working hard and never complain. I have given full power to you. Don't they know how to stop you? How much glass like that has been sold? Recover it all! No matter whether it is from the countries in the Western Regions or the merchants from the Tang Dynasty, you must pay them twice the price as compensation, and replace all the glass for free!" After saying that, Li Hong walked into the hall without looking back.

Bai Chun almost fainted when she heard Li Hong's indifferent voice! She knew better than anyone how many defective products there were and how many were sold. If she recovered all of them and paid twice the price and replaced the glass for free, it would be a shocking expense!

"Master..." Bai Chun cried out sadly.

"Those who disobey orders will be beheaded." Li Hong's tone was indifferent and full of ruthlessness and coldness.

The raindrops became bigger and bigger as time went by, and Bai Chun and the other two, Ren Lao Ren Yuan, watched the carriage slowly drive away from the main building entrance. Xia Zhi and the others secretly patted her shoulders to comfort her, and hurriedly followed Li Hong into the hall.

Li Hong was sitting on a recliner in front of the huge floor-to-ceiling window on the fourth floor, while Xia Zhi was serving him carefully and gently beside him. The rain outside seemed like Li Hong's mood at the moment.

"Master, why don't we call them in?" Xia Zhi glanced out the window.

In the pouring rain, Bai Chun knelt in the rain with his straight and thin figure, and behind him, on the left and right, were two people lying on the ground, working hard without complaint.

"Why are you shouting at her? If she wants to kneel, just kneel down. If you have done something wrong, you should be aware of the consequences!" Li Hong said coldly, obviously still angry.

"Master, Bai Chun's health is not good. If she gets sick, your Chamber of Commerce won't be able to open. Aren't you still counting on her?"

"Rely on her? Rely on her to bring down Taiyi City sooner or later. She is so reckless and reckless. Ask her how much money Taiyi City has lost because of her reluctance. Do I need money? Does the Tang Dynasty need money? In the past few years, I think she has become too greedy to make money. She even sells such defective products. No matter how much money Taiyi City loses, I can bear it, but the reputation is gone, and that cannot be recovered! Don't you understand this, Xia Zhi!"

"Yes, I know my crime." Xia Zhi saw that Li Hong was still very angry, so she didn't dare to say anything and quickly bowed her head to apologize.

Li Hong sighed deeply and said helplessly: "Go ahead, call her in. It's not easy for you these few days. You don't have a husband at this age. Should I marry her off?"

"Master, you can't do that." Xia Zhi knelt down quickly and said.

"Why?" Li Hong stood up from the recliner, looking at the blurry Taiyi City in the mist, and then at Bai Chun who was kneeling downstairs.

"Master, you know that Bai Chun only has you in her heart. She has been busy all these years just because she doesn't want to disappoint you. Besides, she has never thought about getting married. She just wants to serve you for the rest of her life like a servant."

"Go ahead, go ahead, stop saying nice things." Li Hong looked at Bai Chun who was already a little shaky, and said in a softer tone.

"Yes, sir, I'll go right away." Xia Zhi said, unable to hide the excitement in her tone.

Looking up, I saw Xia Zhi holding a brightly colored oil-paper umbrella and running towards Bai Chun quickly in the rain.

Although he couldn't hear what the two were saying, Li Hong knew through the window that Bai Chun didn't want to get up because of her stubborn look.

Li Hong knew that Bai Chun was feeling upset because her mistake had caused Taiyi City to lose a lot of money, so she was kneeling there so stubbornly and refused to get up.

But she didn't know that Li Hong didn't care about the money at all. What he cared about was the golden signboard of Taiyi City and her personal reputation!
