I just wrote a love poem, how did that make me so powerful?

Two small stools were placed in the courtyard, one for Li Yedao and one for Jingmo.

There was a small table in front of him, with several sheets of paper spread out on it.

Li Yedao held a pen in his hand, writing in a small notebook with his head down, occasionally glancing up at the person standing in front of him.

Jingmo is even more exaggerated...

He rested his chin on his hands, tilted his head back, and stared straight ahead without blinking.

Standing in front of them was Xu Qing.

He pointed to the microscope:

"Look, the angle of this convex surface can magnify an object more than ten times. If you combine the two pieces and repeatedly adjust the focus, you can achieve magnification of several dozen times."

Think about it, those things you can't see with the naked eye. Tiny particles in the blood, invisible dirt on a wound—if you could see all of that, how precise could you be when administering medication?

As Li Yedao listened, he quickly took notes, while constantly asking questions.

"What if I use different crystals to polish it..."

Jingmo went even further, asking, "Big...brother, will I be able to see those protozoa you mentioned in the future?"

Xu Qing nodded, her tone very patient.

"Yes, protozoa. As long as you make a good microscope, you can see everything, including the cocci, bacilli, and so on that I mentioned before."

Jingmo asked excitedly.

"Can you see it with this microscope?"

Xu Qing smiled and said, "To see them clearly, a regular microscope won't work; we'll need an oil immersion microscope. We'll study that later..."

Gu Zhiyi stood at the moon gate, rubbed her eyes, and whispered something.

"Is this correct? Am I seeing things?"

Su Man stood beside him, an irrepressible smile playing on her lips.

She patted Gu Zhiyi on the shoulder and whispered a reply.

"You're not seeing things, let's go. It seems our worries were unnecessary."

She didn't go in to disturb them, but turned around and pulled Gu Zhiyi outside.

After taking two steps, the two of them turned back to look at the scene in the courtyard at the same time.

I felt to myself: It's unbelievable...

……

In the courtyard, Li Yedao's hands were still trembling slightly as he put away his microscope.

He carefully wrapped it in a soft cloth and placed it on the table with more care than he had ever seen any rare treasure.

He turned around, glanced at the darkening sky, and asked a question.

"By the way, regarding Miss Song's matter, and these two things, once we agreed, where is the person who was poisoned?"

Xu Qing understood that he was asking about Sun Decai, and nodded.

"He's still being held in the county jail for now; he's not dead, just hanging on by a thread."

Without saying anything more, Li Yedao picked up his medicine box and left.

Jingmo quickly picked up his suitcase and followed.

Xu Qing led them through two streets to the prison gate.

Zheng Youde had already received the news and was waiting in advance.

He saw Li Yedao and came up to greet him.

"Dr. Li, thank you for your help."

Li Yedao waved his hand, "No need for formalities, let's go and take a look first."

……

Inside the prison cell.

Sun Decai was still the same as before, lying on a pile of straw in the corner of the cell, covered with a quilt.

The skin color of the exposed hands and face was no longer discernible.

His cheeks were sunken, and his lips were cracked with several black ulcers.

The skin around the eyes looked corroded, with an unnatural bluish-gray tinge.

He was still breathing, but each breath was shallow and short, as if he might stop breathing at any moment.

Li Yedao examined Sun Decai's complexion, nails, and lip color under the lamplight. Then he reached out and flipped up Sun Decai's eyelids, and pried open his mouth to look at his tongue.

Then, he gently pricked the back of his hand with a silver needle.

After the needle was pulled out, the blood seeping from the wound was dark black and had a faint putrid smell.

Li Yedao examined the silver needles under the lamp for a long time, then stood up and walked into the corridor outside the cell.

He washed his hands with the alcohol he carried with him and said:

"It is indeed a very potent poison, but it was only because it encountered me that it survived. However, it's hard to say how well it will recover."

Xu Qing pressed on, "Can you speak or write?"

Li Yedao nodded.

"Although the amount of poison was heavy, this person was not destined to die. He may have been weakened by alcohol and sex, so the toxins did not travel quickly through his body. His internal organs were not completely rotten. We will first use the appropriate antidote to keep him alive, and then regularly use my prescription to cleanse and administer the medicine. As for the rest, we will leave it to time."

Li Yedao spoke while Jingmo took notes.

After he finished writing it, he handed it to Zheng Youde.

Zheng Youde said happily, "Thank you so much for your guidance, Dr. Li!"

Li Yedao smiled and said, "No need. Everyone knows my temperament. You might not be able to find someone to treat you, but I love taking on difficult and complicated diseases, especially strange poisons."

After finishing his work in the prison, Xu Qing escorted Li Yedao to the Zhuangyuanlou Restaurant to rest.

He went to bed early.

……

The next morning, Xu Qing got up early, mainly to see how the new house was being built.

When we reached the village entrance, we could see those newly built houses in the distance.

The blue bricks and gray tiles, towering above the surrounding mud-brick and thatched houses, looked exceptionally neat in the morning light.

The workers are packing up their tools, preparing for today's work.

Xu's mother stood in the courtyard, holding a bowl of water, and was handing it to a craftsman covered in ash and mud.

Xu Qing watched for a while, a smile appearing on her lips.

As he stepped into the yard, he noticed a pile of lime in the corner.

But the pile wasn't very big, and it didn't look like enough.

He glanced at the adjacent outbuildings and his heart skipped a beat.

The outbuildings were not entirely made of blue bricks. The walls were only half-built, with the lower half made of blue bricks and the upper half made of adobe bricks, with another layer of blue bricks on the outside. It looked like they were reluctantly put together.

He walked over, squatted down, rubbed the mortar in the corner of the wall with his finger, looked up at the half-section of the adobe wall, and frowned.

He turned to a craftsman who was tidying up his tools and asked him.

"Master, why aren't you using lime mortar? And why isn't glutinous rice paste mixed in? Also, why are the outbuildings made of adobe bricks now?"

The craftsman glanced at him hesitantly, then looked in the direction of Xu's mother, and lowered his head without saying a word.

The other craftsman in the narration seemed not to hear, keeping his head down and simply putting away his trowel and plumb bob.

Xu Qing sensed something was wrong, walked up to her mother, and asked in a low voice.

"Mother, what's going on with the wall in the side room?"

Xu's mother sighed and lowered her voice.

"There's not enough lime. The places nearby that sell lime say they're out of stock, and even if the Xu family wanted to pay more, they couldn't get any. The craftsmen said that the outbuildings will be built with adobe bricks first, and then covered with a layer of blue bricks. That's not bad, much better than a typical adobe house."

Xu Qing's brows furrowed even more.

"How could you not be able to buy lime? There's a lime kiln in our village, isn't there?"

Xu's mother shook her head, lowering her voice even further.

"They say that Wang the rich man said he wouldn't send us any more lime."

Xu Qing remained silent for a moment, then rolled up his sleeves.

"Which rich official is in charge of such a wide area?"

Xu's mother pointed to the east end of the village, to the cluster of large, green-tiled houses surrounded by courtyard walls.

"It's that family at the east end of the village, Wang Dafu. He owns several hundred acres of land here and also helps the village headman with the accounts. His words carry more weight than Third Uncle's."

Xu Qing dusted off his hands and turned to walk towards the east end of the village.

Xu's mother called out from behind, "Where are you going?"

Xu Qing answered without turning his head.

"I'll go ask Wang the rich man what business is it of his that I'm repairing my house?"

……

The gate to Wang Dafu's courtyard was even more impressive than the newly built house of the Xu family.

Two large black-lacquered doors with copper door knockers.

Above the door hangs a plaque with the four characters "耕读传家" (Passing down the family tradition of farming and reading).

The handwriting is neat, but the color looks a bit old.

Xu Qing knocked on the door knocker, and a voice answered from inside. A servant in a short jacket opened the door and looked Xu Qing up and down.

Who are you looking for?

Xu Qing: "I need to ask your master something."

The servant hesitated, wondering whether to let him in, when a lazy voice came from behind him.

"Who is it so early in the morning?"

A young man in a silk shirt walked out of the courtyard.

He was about twenty years old, with a fair complexion, holding a paper fan in his hand, tapping it in his palm without opening the fan.

He saw Xu Qing, raised an eyebrow, and spoke in a dismissive tone.

"Hey, isn't this the Xu family's son? What's wrong, the new house construction can't continue?"
