"What kind of knowledge is that?"

Yi Shuihan asked.

He had never even heard of biochemistry or physics.

"My fabricated knowledge."

Xiao Qingyin smiled.

How could she possibly reveal everything?

I was just teasing him.

Yi Shuihan: "..."

This woman is never serious.

"You wouldn't be spouting nonsense about divination techniques, would you?"

“No, that’s not it,” Xiao Qingyin replied. “I still know a little bit.”

It's impossible to memorize a math textbook; you can only summarize and organize the basics of statistics, probability theory, and geometry.

Just give them a formula and they'll be stuck with it for ages.

"It will take a few days before I can give it to you."

"Okay. Thank you for your help."

Yi Shuihan expressed his gratitude.

He thought for a moment and then added, "You can tell me about your English proficiency, but don't tell anyone else."

Others aren't as kind as him. If they encounter a ruthless person, they'll surely devour this woman completely.

"Don't worry, I'm aware of that."

Xiao Qingyin smiled.

There aren't many.

Yi Shuihan secretly grumbled to himself.

If this woman were truly shrewd, she wouldn't have been tricked by Bai Musheng in the first place.

He still needs to keep a close eye on her, lest this woman be foolish enough to fall for someone else's tricks again.

...

In the following days, Xiao Qingyin was busy with follow-up examinations for several of her patients.

Yun Wanyin and Qiu Sanniang are slowly recovering, and the Crown Princess's condition has improved significantly.

"I estimate that after two more follow-up visits, you will be fully recovered."

Xiao Qingyin said to the Crown Princess.

"If you pay more attention to your diet and daily routine, it generally won't recur."

"Thank you."

The Crown Princess looked grateful.

She has recently returned to her pre-pregnancy state and feels more relaxed and at ease than ever before.

The Crown Prince also started sleeping at her place more often.

Since he was still taking medication, they didn't do anything but chat under the covers.

But she still hopes to prepare early.

"I would like to trouble you to help me get in shape so that I can get pregnant as soon as possible."

Xiao Qingyin did not approve of this approach.

"I suggest you prioritize your health."

She advised.

The Crown Princess sighed.

“Consort Wang stubbornly refuses to admit that she has ill intentions. She is also the granddaughter of Grand Secretary Wang. The Third Prince is currently enjoying great power and has few supporters. It is not appropriate for me to make a move against her at this time. Her attitude has changed drastically recently, and she intends to consummate her marriage with His Highness.”

If Wang Liangdi gets pregnant first, she will be at a disadvantage.

Seeing that she was determined, Xiao Qingyin had no choice but to agree.

"Alright, I'll prescribe another one for you."

The Crown Princess was overjoyed and had several carts full of things packed for Xiao Qingyin to take back.

Even Ji Yunhua was a little envious when he saw it.

“There’s no way to make money doing business compared to treating patients. Look, the consultation fee for one patient is equivalent to my income from several years of business.”

Xiao Qingyin rolled her eyes at her.

He simply asked her, "Do you want to study medicine? I'll mentor you for free."

Ji Yunhua immediately waved his hand.

"Forget it, I get dizzy and lightheaded just looking at medical books, I can't do this job."

Xiao Qingyin scoffed.

I knew this guy was a complete idiot—I had to keep my mouth shut.

Ji Yunhua would not allow Xiao Qingyin to look down on her.

"I can't read medical books, but I know the glassmaking formula by heart. The workshop has already prepared the materials and we can start making glass soon."

Upon hearing this, Xiao Qingyin became interested.

"When will the furnace open? I'd love to come and join the fun."

She hadn't forgotten her promise to the beauty to make it a dozen ponies.

"tomorrow."

"Okay, I'll go to the workshop with you tomorrow."

The next day, when Xiao Qingyin arrived at the workshop, she found that Yi Shuihan had also arrived.

Is your injury getting better?

She had scheduled a follow-up appointment, but Yi Shuihan didn't have time, so she didn't get to see him.

"It has healed."

Yi Shuihan replied.

Ouyang Xiuqi brought over the glass ball he had just blown and handed it to Yi Shuihan.

"Congratulations on your promotion to General of the Cavalry."

Xiao Qingyin was surprised.

"You got promoted?"

Yi Shuihan nodded: "Because of my merit in suppressing the rebellion, His Majesty appointed me as a general, commanding the original Southern Five Camps and the newly established Firearms Camp."

"Then I really have to congratulate you."

Xiao Qingyin smiled.

He thought to himself: The cannons must have been invented by Yi Jiu, I wonder if he is in charge of the artillery battalion.

Yi Shuihan took the glass ball that Ouyang Xiuqi gave him, looked at it from left to right, but couldn't figure out its purpose.

I had no choice but to ask, "What is this for?"

Don't tell him it's just a bumpy ball, only good for decoration.

Ouyang Xiuqi smiled mysteriously.

"For magic tricks."

He led the group to a dark room.

After lighting the candle, place the glass ball next to the candlelight.

A vibrant array of colors instantly filled the room, even covering their clothes.

"Slap! Slap! Slap!"

Xiao Qingyin applauded enthusiastically.

I never expected to see a light show in ancient times.

The Earl of Jian'an truly lived up to his reputation as a master; he understood how to utilize light and shadow even before he had any experience with glass.

Ouyang Xiuqi stared intently at Ji Yunhua's face.

Actually, after the glass ball was finished, the first person he thought of was Ji Yunhua, and he wanted to share these light and shadow effects with him.

I was just a little embarrassed, so I used the excuse of congratulating Yi Shuihan on his congratulations to show it off.

Ji Yunhua reached out and caught a handful of light spots, and said with a smile, "It's quite interesting. It would be even better if they were butterfly-shaped."
