Although Li Shimin had no obsession with cleanliness, he still had a few blue veins popping out of his forehead when he thought of the black pig covered in mud and smelly body.

Li Muyun, it was the boy Li Muyun again. He hadn't seen the bastard come to wander around here for several days. Li Shimin guessed that the boy must be holding some bad water. Now he saw that it was indeed the case.

"Come on, go and bring Li Muyun to me!" His Majesty Li Er, who became more and more angry, simply stopped brushing his teeth and ordered a bastard who dared to cheat him. As for Changle, who offered a toothbrush..., OK, Changle was automatically ignored by Li Er.

When Li Muyun was brought to Li Er, he looked completely confused and didn't seem to know what was going on: "Your Majesty, are you looking for me?"

The great Emperor of Tang Dynasty endured the disgust in his heart, put his toothbrush in front of Li Muyun, bit his back teeth and asked, "Did you make this thing? Can you tell me what this thing is made of?"

"Toothbrush?" Li Muyun blinked and said to the truth: "Your Majesty, this thing was indeed made by me. The main materials are bamboo slices and pig bristles."

"Why do you want to give this thing to me? Do you know that this is deceiving the king!" Li Shimin looked at someone with an innocent look and felt like murder.

Li Muyun was not scared by Li Er, but said seriously: "Your Majesty, how about you let me settle the calculations for you first?"

"Think, you can calculate it. If you can't figure it out, I must hang your head on the city gate!"

Li Shimin was almost madly angry. He knew that his daughter would not have come up with such a way to cheat him. The reason why he brought a toothbrush made of pig hair in front of him must have been instructed by others. And this "other" was impossible for Li Muyun, a bad guy with sores on his head and pus flowing under his feet.

Therefore, if Li Er did not give this bold and arrogant boy some education, he would feel ashamed of the people of the world.

Just as Li Er was thinking about how to mess with Li Muyun back, the boy's hateful voice came from his ears: "Your Majesty, I have nearly 30 million people in the Tang Dynasty. Think about it, if each person buys a toothbrush, even if one toothbrush is a penny, it would be an income of 30,000 yuan. Moreover, toothbrushes cannot be sold so cheaply. Even if we sell three cents, we will have 100,000 yuan a year."

"And your majesty, toothbrushes are consumables, and no one can use them for a lifetime. Basically, this thing cannot be used in less than a year. So it means that this thing can generate an income of 100,000 yuan a year."

After hearing Li Muyun's explanation, Li Er couldn't help but become more angry and pointed at his nose and cursed: "100,000 yuan a year? You kid is already very rich now, are you still missing these 100,000 yuan? For the sake of 100,000 yuan, you actually asked me to use pig hair to brush your teeth, you..."

Just when Li Shimin was about to ask someone to beat Li Muyun out and drag him to death, someone's innocent voice came into his ears: "Your Majesty, this business belongs to Princess Changle, not mine!"

"Hmm?! The toothbrush is Changle's business?" Li Er was stunned for a moment, and suddenly felt like he was losing money after being silenced.

Li Muyun nodded heavily, took Li Er's words and said with great certainty and affirmation: "Your Majesty, it is indeed Princess Changle's business, so you have to take good care of this boss. Only when you see you are using it will the adult below use it. If the adult below uses it, the people will use it. Do you think this is the reason?!"

Li Shimin nodded mechanically. It’s 100,000 yuan a year. This money is really not a small amount. He came out so far this time and probably couldn’t spend 50,000 yuan. If he earned 100,000 yuan a year, wouldn’t he be able to go out and play every year!

As for the business of toothbrushes, this is just like that. How could a little girl make a 100,000-yuan business be handed over to her? In the end, it was not necessary for Emperor Changsun to control it. What is the difference between what Empress Changsun controlled and what Old Li personally controlled?

Thinking of this, Li Er looked down at the toothbrush he held in his hand, his eyes became more eager, he raised his hand and stuffed it into his mouth and poked it a few times, and he felt that it was not so disgusting, and his mood couldn't help but turn from the lightning and thunder just now to the clear sky: "Come here, Changle has good filial piety, a pair of jade Ruyi, a pair of croaker-headed gold hairpin, a piece of jade pendant, a hundred silk and satin, and a hundred taels of gold!"

This attitude has changed too quickly, right? When I heard that the business belongs to my own family, I immediately changed my face!

"Huh?! Why are you still here? Didn't you say you're going to Shuozhou today? Why don't you prepare yet?!" After Li Shimin ordered someone to give Changle a bunch of good things, he finally noticed Li Muyun's existence again.

"Your Majesty, that toothbrush was developed by me. Do you see if it is..." Li Muyun pinched a few fingers together and rubbed them a few times, with a very obvious intention.

Li Shimin had seen this trick for him, and even if he had never seen it, how could he not understand what he wanted to do when he heard what he meant? But for some reason, he felt angry when he saw him.

So he didn't talk nonsense to him and snorted, "Why, do you think I would let you go of Changle because of this little money? You dare to ask me for a reward, do you think I really won't beat you?"

"Your Majesty, you're 100,000 yuan a year. You're also giving me some sweetness, right?" Li Muyun could see from Li Er's attitude that he didn't plan to continue to pursue the matter. He was much more courageous, so he followed him and continued to bargain.

"Hmph, Li Muyun, Changle's heart belongs to you, so I was bewitched by you, but I am not Changle, and I am not so easily bewitched by you. I have an income of 100,000 yuan a year. Do you think those people who are too poor to afford to eat will really take out money to buy this thing? Do you think I am a fool?"

Li Muyun followed Li Er very hard and pushed the eunuch Lao Long aside: "Your Majesty, although some people don't know how to buy toothbrushes, nobles and wealthy merchants will buy them. Moreover, in order to show their identity, they cannot only buy some toothbrushes made of bamboo. You can definitely make some gold and jade to sell them. Wouldn't such toothbrushes be more expensive than tens of thousands of ordinary toothbrushes!"

"No, no, I won't be fooled by you. You have used your mind in the wrong place!" Li Shimin turned his head and glanced at Li Muyun, and continued in a good mood: "But, if you promised me a condition, maybe I would consider rewarding you something."
