Ying Zheng's decree was quickly passed down to all counties and prefectures across the country. Although the officials did not understand why His Majesty was so concerned about such a small matter, they still diligently arranged it.

The minor officials went to every village and town to publicize the importance of hygiene with drums and gongs, and the official newspapers published detailed information on the importance of hygiene, which greatly enhanced the hygiene awareness of the people of Qin.

Nowadays, living conditions are better and people are more concerned about their health. Keeping clean and hygienic makes them feel comfortable and can prevent most diseases in advance. Why not do it?

Therefore, high-quality and inexpensive soap has become a must-have daily necessity for every household.

In a small mountain village in Guilin County.

Aunt Feng was returning from the market with a bamboo basket on her back. Her simple face showed the joy of returning home with a full load. When she was almost at the door of her house, she shouted loudly.

"Tiger boy, come and open the door for mother!"

"Tiger boy, mother brought you some delicious food. Where is she? Tiger boy!"

After calling out several times without hearing any response from the child, Aunt Feng suddenly became anxious. She ran to open the door and looked around for the familiar little figure.

But the house was still silent.

It is spring plowing season now, and her husband went to the fields early. It was inconvenient for her to take the child with her to the market, so she asked him to look after the house. Unexpectedly, when she came back, the child was gone.

Aunt Feng was terribly worried. Where could a six-year-old child have gone? Could he have wandered off to the mountains and forests out of play? There were plenty of ferocious beasts there...

When she was at a loss, an idea suddenly came to her mind.

Suddenly remembering that a mouse had stolen food yesterday, Tiger Boy threatened to catch the nasty mouse and roast it to eat. At that time, the adults just thought it was childish talk and laughed it off.

Holding on to the last glimmer of hope, Aunt Feng hurried to the cellar behind the house.

Sure enough, a chubby little kid was standing there, grinning foolishly, holding a fat mouse in his hand.

"Tiger boy, why are you here? I'm almost driving my mother crazy, ah..."

"You're so black, it just so happens that your mother bought some soap, so I'll give you a good scrub today."

"Mom! You're back! I caught the mouse that was eating our food. Isn't that awesome? I'll roast it and eat it later."

Tiger Boy stared at the fat mouse, treating it as a delicious barbecue, with a look of drooling greed written all over his face.

Perhaps sensing a fatal threat, a red light flashed in the mouse Doudou's eyes. When the child relaxed his vigilance, he turned his head and opened his fang-filled mouth, ready to bite hard.

Seeing this, Aunt Feng's mind went blank. In a panic, she threw the hard soap in her hand over.

With a "bang", the soap hit the mouse's head accurately, knocking it unconscious. The soap and the mouse fell to the ground together.

The lightning-fast scene took Tiger Boy time to react. He looked blankly at his limp mother and asked timidly.

"Why are you hitting the mouse, Mom? I've already caught it..."

"You little brat, didn't you see that rat almost bit your hand? What if you get sick from being bitten? Come here and wash your hands quickly."

Recalling the serious instructions of the officials, Aunt Feng grabbed Hu Wa's ears with lingering fear, spanked his butt several times, stepped on the mouse to death, and buried it in a random hole.

When Tiger Boy saw that the delicious barbecue was gone, tears welled up in his eyes.

Aunt Feng did not try to comfort the child. She picked up the soap and took the ignorant and fearless child to wash, scolding him all the time.

"Kid, don't you know that mice are full of bugs?"

"Wow...but, there's no meat left..."

"You're so hungry! Mom bought some pork at the market today and will fry some pork lard for you when she gets home."

The child looked so pitiful that Aunt Feng, as his mother, couldn't bear it and had no choice but to comfort him.

Tiger Boy burst into laughter when he heard this, his head filled with the aroma of lard, but his mother's warning that followed made his face turn pale in an instant.

"Tiger boy, remember this: you can't catch mice, let alone eat them, or else bugs will crawl out of your stomach in the middle of the night."

"Woooooooooo!"

"I don't want worms growing in my stomach... woo woo... I'll never catch mice again..."

"Okay, okay, from now on, you have to wash your hands before eating every day, otherwise you will get bugs."

Seeing that the child finally realized the seriousness of the matter, Aunt Feng nodded with satisfaction. This brat was too bold. He would never learn his lesson unless he was scared.

No one expected that the source of a terrible epidemic would be eliminated so silently.

The funny thing is, the biggest contributor was actually a bar of soap...

Under Ying Zheng's swift and decisive government orders, the national health propaganda was successfully completed, and reports were submitted from all over the country.

In the inner hall of Zhangtai Palace, the originally solemn and cold furniture became exceptionally warm.

The floor was covered with a white and soft wool blanket, the hard wooden chairs were replaced with fabric sofas, and fresh and delicious fruits were placed on the table.

Ying Zheng was flipping through the memorials, his handsome brows furrowed tighter and tighter, his deep eyes filled with worry, his knuckles tapped the table, and he closed his eyes in thought.

It is not uncommon for children to suffer from abdominal pain. However, statistics from various counties show that there are millions of such cases, and the symptoms are mostly the same, with frequent abdominal pain and loss of appetite.

This was no longer a trivial matter. With such a widespread illness, Ying Zheng almost suspected it was an epidemic, and he wondered if the Imperial Hospital could treat it...

"A Zheng, what's wrong? What are you worried about?"

"Yuening, it's okay, just a little bit..."

"Well, just take a look."

Ying Zheng didn't want to trouble his pregnant wife, but after seeing her angry face, he compromised unconsciously.

Chu Yuening snorted softly, took the memorial and read it carefully. When she saw the shocking number of patients, her pupils suddenly shrank, and she subconsciously bit her red lips with her teeth, her face full of worry.

In the past, the environment was harsh and the sanitary conditions were poor, so she guessed that there were cases of ascariasis, but she never imagined that the number was so large.

Although ascariasis is not immediately fatal, it can easily spread to other organs over time, causing symptoms such as intestinal perforation, peritonitis, and pneumonia. If not treated in time, it may even lead to death.

What's more, children's organ functions are inherently more fragile than those of adults. For them, ascariasis is undoubtedly a serious illness.

"A Zheng, this disease is called ascariasis. Although it's not an emergency, it can be life-threatening, especially for children."

"It's so serious... I've been negligent. I'll order the Imperial Hospital to develop a countermeasure."

Ying Zheng's expression froze, a hint of anxiety appeared between his brows, and he immediately wanted to call Zhao Gao to pass on the order.

Chu Yuening held the man's big hand, shook her head slightly, exchanged a light yellow spiral-shaped item from the system, and displayed it in her palm.

Lowering his eyes to stare at the strange object in the palm of his white and tender hand, Ying Zheng raised his sword-like eyebrows slightly, and stared straight into his wife's bright eyes, waiting for her to explain.

"A Zheng, this is pagoda candy, it has the effect of paralyzing and expelling roundworms."
