When Li Chengqian came to Empress Changsun's residence, Li Er was still discussing the issue of meat prices with Wei Zheng.

The little brat bowed properly and ran to Changsun: "Mother, I see you are here."

Empress Changsun smiled docilely and flicked Li Chengqian's forehead: "You skin monkey, you can remember to see your mother with nothing to do."

"It's the child's fault. In the future, no matter how busy the child is in school, he will always come to see him." Li Chengqian's mouth was so sweet that he made Queen Changsun happy after a few words. When the time was right, he took out the only piece of unused soap and showed off: "My mother, look."

Queen Changsun really didn't recognize her, so she took her in her hand and looked at her for a moment: "What's this?"

Li Chengqian said proudly: "This is called soap, for bathing. Do you know that ink was stained with children's hands in the past, it would take more than ten times to wash it. After using this, it only takes twice to clean it." As he said that, Li Chengqian raised his little hand and put it in front of Queen Changsun.

Smelling the faint fragrance on his son's hands, Empress Changsun was a little moved: "Chengqian, how to use this soap?"

Li Chengqian said: "Just wet with water and apply it on your body. It can also be used to wash hands and laundry in normal times."

"That's so simple?" Empress Changsun looked at the soap in her hand again for a while and decided to give it a try in person.

Filling water and cleaning. Under the guidance of Li Chengqian's "professional", the Empress mastered the use of soap with a quick grasp. She was also very interested in soap. She pulled her son and asked, "Chengqian, tell her mother, where did this soap come from?"

"It was studied by Li Dejian, a child's attendant." Li Chengqian's little head was raised high, and those who didn't know would even think it was studied by him personally.

The queen continued to ask, "Then has he said how valuable this thing is?"

"This..." Li Chengqian scratched his head and said whispered: "Child...forgot to ask."

"You kid are always lost." Empress Changsun clicked on Li Chengqian's head, thought for a while and explained: "When Li Dejian enters the palace again tomorrow, remember to ask."

"What are you asking!" Before Li Chengqian could answer, Li Er's voice came from outside.

Time is not long, and the handsome old man walked in from outside with a calm face.

"Son, please see your father." Li Chengqian saw Li Er and mouse, as if he was weak, pitiful and helpless.

"Your Majesty." Empress Changsun felt a little reluctant and greeted Li Er: "Why did you return so early today?"

"It's not for this rebellious son." Li Er glared at his son and sat on the couch aside in anger: "Prince, have you issued a warrant a few days ago to let Li Dejian, the bastard in Chang'an and Wannian counties, purchase grease."

‘Baji’ Li Chengqian knelt down without saying a word and showed that he did it himself.

Empress Changsun felt sorry for her son. Before Li Er had gone wild, she advised with kind words: "Your Majesty, what's wrong? Is there anything you can't say?"

"Guanyin maid, you don't know." Li Er said annoyedly: "It's okay for these two little bastards toss in the palace for a while, but this time they actually went outside the palace. Especially this rebellious son, a warrant, has caused the meat price in the entire Chang'an to rise by 20%. Wei Zheng's impeachment memorial has been handed over to my desk."

"This..." Empress Changsun frowned and looked at Li Chengqian: "Chengqian, what's going on? Explain to your father quickly."

"Yes, it's soap. Li Dejian said that the oil of chicken, duck, cattle and sheep must be used to make soap." Li Chengqian gave Li Hao without hesitation and added: "He also said that after the soap is made, the income will be equal to the child. The father and queen, the child didn't want him to respond to him, but... but later he thought that the money he earned could help the queen share some of the expenses in the palace, so he agreed to him."

As the saying goes, children are their own good.

Li Chengqian's words were true or false, but it moved Empress Changsun so much that she turned red: "Your Majesty, it's my fault that is my incompetent. If you want to blame him, blame me. Although Chengqian did something wrong, he is also filial. I, as a mother, have a responsibility."

"You, Guanyin maid, what are you doing?" When Empress Changsun cried, Li Er didn't care about teaching her son a lesson and quickly comforted her: "I didn't say that I would do anything to this rebellious son, but just wanted to warn him and Li Dejian's bastard."

"Really? Your Majesty really doesn't blame Cheng Qian?"

"No, no."

...

...

Li Er said it was not strange, but his actual action was to leave Empress Changsun's residence and immediately sent someone to summon Li Hao.

Li Hao, who had just returned home from the palace, was thinking about training clothes. When he heard that the palace was summoned, he rushed to the palace without saying a word.

This kid Li Chengqian looked unreliable and was very quick to do things. He actually got the soap problem so quickly.

After thinking about entering the palace, I saw Li Chengqian standing there like a wooden stake from the door of Li Er's study.

"Your Highness, what are you doing? Are you waiting for me?" Li Hao greeted excitedly.

Li Chengqian raised his head and looked at Li Hao with a rolling eyes and hanging expression.

Li Hao:??

What's wrong? Why doesn't it look like something good?

Just as I was about to ask what happened, Li Er's voice came from the study: "Li Dejian, get in for me."

With his head down and his chest in his arms, Li Hao rushed into Li Er's study with great sincerity: "Your Majesty has great blessings and great fortune, and you will never forget it..."

Li Er waved his hand and interrupted Li Hao's flattery: "Li Dejian, do you know your mistake?"

When Li Er heard that he was using "wrong" instead of "sin", Li Hao relaxed his nerves slightly and lie down to the ground: "I know I am wrong."

What is this kid doing? Li Er was stunned, but soon came to his senses and asked with a calm face: "Where is the mistake?"

Yes, where was I wrong?

Li Hao blinked his ignorant eyes and looked at Li Er with an innocent look.

The little eyes were exactly the same as when he woke up after he was unconscious that day.

Li Er's heart softened, and he rushed to his mouth and dragged it out to beat him: "Wei Zheng wrote a letter to impeach you and the prince maliciously bought grease and raised prices. What are your arguments about this?"

Uh..., that's all?

That Heizi has a grudge against me, right?

Li Hao said bitterly: "Your Majesty, I and the prince have no intention of maliciously raising prices. They purchase oil and fat to make soap. This product has strong detergent power and is easy to use..."

"I don't want to hear this." Li Er interrupted Li Hao again: "I asked you to come and tell you that this matter has ended here. If I let me know that you are buying grease in the future, you can go to Lingnan to farm."

"No!" Li Hao agreed very happily.

If you don’t let it do it, just like someone cares about it.

I hope you won't ask me to make this thing next time.
