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

Li Yedao took two steps with his hands behind his back before turning around to speak.

"Our sect of divine healers has dedicated our lives to treating rare and difficult diseases. If you asked me to go to the capital and spend every day preparing medicinal meals for someone, I'm afraid I wouldn't be able to stand it."

Xu Qing didn't reply immediately. He remained silent for a while, then slowly raised his head, his eyes gleaming with a different kind of light.

"What if I could give you something...something you'd be interested in studying for the rest of your life?"

Upon hearing this, Li Yedao was taken aback for a moment, then burst into laughter and turned to look at the boy standing beside him.

"Jingmo, listen to this kid. He's even more arrogant than you. You said you wanted to cure the most difficult bleeding disease in the world, and he said he'd find something I could study for the rest of my life."

Jingmo, being a young man, raised an eyebrow upon hearing this and retorted defiantly.

"Hey, sir, what makes you say that? I don't believe you. You're just lying to Master, aren't you?"

Xu Qing glanced at Jing Mo and calmly corrected him.

"Who are you calling 'uncle'? I'm just a few years older than you, call me 'brother'."

Jingmo was led astray by him and couldn't quite grasp the situation for a moment.

"Is that the point, sir?"

Xu Qing remained unhurried. "Call me brother."

Jingmo opened his mouth slightly, but ultimately gave in and changed his mind, pouting.

"Okay, brother, is that the important thing?"

Xu Qing's lips curled into a confident smile.

"Whether it's the key point or not... we'll find out in three days. If I can't come up with something that the Divine Doctor is willing to study for the rest of his life, I'll become his watchdog and respond to his barks."

After hearing this, Li Yedao was taken aback at first, then burst into laughter.

"You little rascal, this isn't punishment for you, it's a reward for yourself! Come work as a gatekeeper at my Divine Healer's Sect, and there will be plenty of people lining up to do it."

Xu Qing clasped his hands in a fist salute and said solemnly.

"I wouldn't dare joke around, but if I can produce that item, I hope the divine physician can go to the capital to treat Yao Yao. You don't need to stay there all the time; you just need to visit her every now and then and adjust the prescription as needed."

Seeing his serious expression, Li Yedao's smile faded, replaced by a serious scrutinizing look. He remained silent for a moment, then slowly nodded.

"Very well... I'll agree to your request. After all, it's been many years since anyone dared to bet with me. Three days should be enough for you to prepare."

……

……

Three days later, at the Xiao family's blacksmith workshop.

Cheng the blacksmith and his apprentices gathered around a furnace, watching Xu Qing fiddling with something using a thin iron pipe and two polished crystal pieces.

The crystal was borrowed from Su Man.

In the storeroom of Zhuangyuanlou, there happened to be a natural crystal with extremely high transparency. It was originally intended to be used as a paperweight, but Xu Qing borrowed it and ground it into two pieces, one convex and one concave.

Xu Qing embedded the two crystal pieces at both ends of the iron pipe, adjusted the spacing, fixed them with fine screws, and then carefully wiped the surface of the crystals.

Then a particularly finely crafted wire rod made by the blacksmith was placed on it.

He picked up the iron pipe, squinted one eye and peered at it for a while, then put it down, readjusted the distance, and peered at it again.

Cheng the blacksmith watched from the side, completely bewildered.

Jingmo, who was next to him, also leaned over to look at his neck, muttering to himself:

"What can you tell from this? It's just a pipe!"

Xu Qing ignored him and brought Li Yedao to Qingdao.

"Dr. Li, please take a look."

Li Yedao was skeptical, but he followed Xu Qing's example and leaned closer to see it.

The moment his eyes met, he froze.

His hand, which was resting on the table, trembled slightly. He then slowly took a step back and leaned in to take another look.

He stared at it for a long time, so long that Jingmo couldn't help but call out from the side.

"Master, Master, what did you see?"

But even this shout didn't bring Li Yedao back to his senses.

After a while, he stood up, looked up at Xu Qing, and spoke with unprecedented seriousness.

"What...what is this?"

Xu Qing smiled slightly and replied:

"This is called a microscope. I figured it out by chance. It allows people to see things that are invisible to the naked eye."

Those tiny filaments you just saw are fibers from a sleeve that stuck to your own hand.

Those round structures were tiny bits of moss that I scraped off with the tip of a knife.

Li Yedao leaned closer and looked at it again, this time for even longer. When he stood up, his fingers were still trembling slightly.

"In my more than forty years of medical practice, this is the first time I've ever seen anything like it."

The shock in his voice was impossible to hide.

Xu Qing readjusted the microscope and took a rough porcelain bowl from the table. It was half-filled with water, which he had just scooped from the water tank in the backyard.

He placed the bowl on the small table, dipped a clean needle tip into the water in the bowl, gently touched it onto the slide, then fixed the slide in place and adjusted the focus.

"Dr. Li, please take a look at this."

Li Yedao bent down and brought his face close to the camera.

I had expected to see something similar to the moss fibers or fabric scraps I had just seen.

But this time, what was in sight was completely different.

Inside the microscope tube was a shimmering, transparent expanse of water.

Countless tiny particles float in the water; some are still, some are moving slowly, and some even smaller ones are swimming rapidly.

They come in various shapes: some are slender lines, winding and meandering;

Some are round and spinning continuously;

There were also some small balls that looked like they were covered in fine hairs, rolling and moving forward in the water.

Those things were so small that without this tube, you couldn't see them even if you put your eyes right up to the water's surface.

Li Yedao's hands trembled even more violently; he had never experienced anything like this before.

He got up from the microscope, rubbed his eyes, and then looked at it again.

He looked at it even more carefully the second time.

The swimming creatures are still there, some moving so fast they leave a faint trail that flashes by in the frame.

When he put down the microscope, everyone could hear the tremor in his voice.

"What...what are these things?"

Xu Qing pointed to the water in the bowl.

"It's that half bowl of water you just saw. There are living creatures in the water that you can't normally see with the naked eye, but you can see them with this."

Li Yedao looked at it again, this time for a long time, so long that Jingmo next to him couldn't help but lean over.

"Master, what exactly is that? You're going crazy!"

Li Yedao didn't reprimand him or say anything; he simply stepped aside and pointed at Jingmo.

"Come and see for yourself."

Jingmo followed his master's example and moved closer to the lens.

His eyes had barely touched it when he abruptly pulled them back.

"Master, what kind of monster is that? There's something moving inside."

His reaction was no longer that of someone indifferent to worldly affairs.

It was the shock that a young person should feel.

He took two and a half steps back, but couldn't resist going back to take another look.

Li Yedao sat on a small stool, his hands on his knees, staring intently at Xu Qing's face.

"Young man, I have practiced medicine for forty years, tasted hundreds of medicinal herbs, and treated countless patients, but I have never... never seen anything like this before..."

He pointed to the bowl of water.

"If every drop of water contains such living organisms, what about the blood? The pus? The lesions?"

As he said this, his voice suddenly dropped eight octaves, and he began to mutter to himself…
