Zhang Heling was greatly distressed when he was reprimanded by Zhu Youtang in his own territory Fengmingyuan. Not only did he fail to show off, but he was also scolded. The most important thing was that he originally only had to pay 20% of the commercial tax. After this unexpected incident, it became 30% of the business tax is collected. But what can I say? Thank God that my brother-in-law didn't tell his father.

"Sir, the Song Army has been summoned." A servant stood at the door and said. He knew that his master was moody and he must have been angry again when he was beating things in the house when he came back today. He did not dare to go in to send a message.

"Let this bitch get in quickly!" Zhang Heling was extremely dissatisfied with the efficiency of Song Jun, a slave. A few days ago, he patted his chest and promised himself categorically that he would definitely send Wang Shu to see the King of Hell. As a result, Wang Shu Not a single hair fell out, and he was still alive and well. He even let his brother-in-law know about this. Of course, he did not rule out that he had underestimated Wang Shu. This old man who had half of his body buried in the loess was far from as simple as he thought. , not a waste...

Song Jun didn't know that the news of his assassination of Wang Shu had been exposed. He happily led a group of scoundrels to ambush Wang Shu on his way to the capital camp every day. But what was puzzling was that he didn't see Wang Shu at all in the past few days. The trace of Shu. This morning, when the Song army saw Wang Shu swaggering on the official road, they were about to call all the brothers out when they suddenly found that Wang Shu was escorted by hundreds of Jinyi guards, and there was actually a Jinyiwei palm print commanding Wan Shu. Tong. Song Jun immediately knew that his plan was in vain, but what puzzled him was that Old Man Wang was too arrogant. He only had to be escorted by hundreds of royal guards. Even the commander of the palm seal had to act as a bodyguard himself.

Song Jun knew that Zhang Heling's sudden call to him at such a late hour must be up to no good, so he wrote a suicide note in advance and asked his brother to send it home. Going to Zhang's house today will be very unlucky!"

"The villain Song Jun has met the young master." Song Jun knelt on the ground anxiously, waiting for Zhang Heling's trial.

"Song Jun, come here." The latter trembled after hearing this, and then slowly moved over on his knees. As soon as he moved to Zhang Heling's feet, Zhang Heling raised his leg and kicked him up and cursed: "Bitch, you are How can you guarantee me?"

Song Jun immediately fell to the ground and begged for mercy: "Sir, I made a mistake. I was indeed waiting for Mr. Wang on his way home, but I don't know why he hasn't passed by in the past few days."

"Hmph, I don't know why, I'm here to remind you!" Zhang Heling picked up the ceramic jug on the table and threw it at it. Song Jun screamed, covered his bloody face, and kept begging for mercy:

"Sir, I made a mistake, please give me another chance!"

Zhang Heling sat on the chair and said with a faint smile: "Forget it, my brother-in-law already knows about this, and you have lost your chance. Prepare a sedan for me, and follow me to Mr. Liu Ge's house."

On the couch in Kunning Palace, Zhu Youtang and Queen Zhang had just finished the Wushan rain. They hugged each other tightly. Zhang Yuer said softly: "I heard that your Majesty brought a woman into the palace yesterday and kept her in Qianqing Palace. , are you planning to make her a concubine?"

Zhu Youtang breathed a sigh of relief, thought about Su Yin's graceful figure, and said with a smile: "Why, are you jealous?"

"No way, isn't it normal for a man to have three wives and four concubines? Besides, you are still the emperor. But... I am still worried that Your Majesty will forget about me when he has a new love in the future." Empress Zhang said coquettishly.

Zhu Youtang smiled and said: "How could it be possible? I promise you today that you will always be the queen of the Ming Dynasty and the master of these six palaces."

Hearing her man's assurance, Queen Zhang buried her head in Zhu Youtang's arms with satisfaction. Zhu Youtang was about to turn over when he suddenly heard "Ouch" from Queen Zhang.

"What's wrong?"

Empress Zhang covered her swollen right face and said, "I have a sudden toothache recently."

Zhu Youtang remembered that he had only cared about his own happiness just now, and he didn't realize that someone else's face was swollen like a steamed bun on his pillow. He was a little embarrassed and asked: "Then why didn't you tell me just now?"

"I also want to please His Majesty, and I am afraid of disturbing His Majesty's interest." Empress Zhang said shyly.

Zhu Youtang immediately turned over and shouted: "Here comes someone, prepare some garlic."

When the palace maids and eunuchs who were keeping vigil outside the door heard this, they immediately ran in and said, "My slaves obey the order."

Empress Zhang asked in confusion: "Why does Your Majesty want garlic? A new trick?"

"No way, mash the garlic, warm it and apply it on the painful area, it can effectively relieve the pain."

Considering the reason for Queen Zhang's toothache, Zhu Youtang let her go that night, got up and started painting on the table. Early the next morning, Zhu Youtang gently kissed Queen Zhang's forehead and said softly: "Get up and see what I have done. The gift you prepared."

Because Queen Zhang had a toothache, she stayed up very late at night before falling asleep. After hearing Zhu Youtang speak, she got up, rubbed her eyes and asked sleepily: "What is it?"

Zhu Youtang took out a small brush from his back and said with a smile: "This is what I improved. I named it a toothbrush."

"Toothbrush" first appeared in the "Trivial Records" written by Wen Ge of the Northern Song Dynasty: "Don't brush your teeth when you get up early, for fear that the roots will be loose and the teeth will be loose and easy to shake. If you suffer from toothache for a long time, you will always brush your teeth with a ponytail."

"Brush your teeth" refers to the toothbrush."

In the "Yuyuan Prescription" of the Yuan Dynasty, it is even more straightforward to record the way people brushed their teeth at that time: "Use a toothbrush dipped in medicine to brush the upper and lower teeth, and then rinse them with warm water."

Before the advent of toothbrushes, people mainly used willow branches to brush their teeth.

It was also mentioned in the "Secrets of Waitai" of the Tang Dynasty: "Every morning when the willow branch is bitten and the head is soft, take some medicine and wipe the teeth, it will be fragrant and smooth."

Here it is clearly stated that every morning, bite the willow branch until soft, apply medicine on it, and use it to brush your teeth.

It can be seen that willow branches are indeed the prototype of ancient toothbrushes.

In fact, it was Emperor Xiaozong of the Ming Dynasty who invented the toothbrush in history. Zhu Youtang, who traveled through time, just copied it and advanced the invention by several years.

Empress Zhang touched it carefully and said with a happy smile: "It's quite unique. How was it made?"

"I asked the imperial doctor. You didn't rinse your mouth for a long time after eating. The food residue was left in the gaps between the teeth. Over time, the teeth developed cavities, which caused the toothache. The imperial doctor recommended that you eat every time After eating, I have to rinse my mouth to clean away the food residue in my mouth. But I thought that the method I used before may not be able to clean it every time, so this morning I asked the craftsman to dig out one end of the slender bamboo board. Make a lot of small holes, then wash the bristles with boiling water, soak them until soft, and finally stuff them into the small holes to fix them." Zhu Youtang proudly showed off his product like a product salesman.

When Empress Zhang heard that Zhu Youtang had invented the toothbrush specially for her, she was even more delighted and said: "Your Majesty is so smart and talented, I admire you!"
