"Not bad, that's an idea!"

"And those two iron bars, I suppose they're for training arm strength..."

When Li Jue heard that Old Li was so knowledgeable, he immediately asked in confusion.

"Old Li, aren't you the Palace Gatekeeper? How come you even know this?"

"oh?"

Upon hearing this, Li Shimin immediately realized that he had let something slip and quickly began to explain.

"I fought in wars when I was young. It was because of my meritorious service in wars that I was able to get a job as a palace gatekeeper to retire in!"

"Oh oh oh..."

Upon hearing this, Li Jue immediately ceased to doubt, for the Tang Dynasty did indeed have a tradition of converting military merits into official ranks. Especially in the early Zhenguan period, many outstanding military figures were converted into official positions according to the rank of nobility, and these official positions were not of low rank.

However, in the later period, with the Tang Dynasty's successive victories in foreign wars, more and more people in the Tang Dynasty were granted titles, and the titles became somewhat devalued, only worth 70%, 60%, or even 50% of their original value when converted into official positions.

Even so, there weren't enough official positions to go around in the Tang Dynasty, and many people who wanted to transfer couldn't get a chance.

Old Li's position as the palace gatekeeper was certainly fortunate to have caught a good time.

If he were to use his title now, he might not even be able to become a city gate guard, let alone a palace gate supervisor.

Li Jue led Old Li and his aunt to the infirmary. Old Li once again transformed into a curious old man, examining all the facilities inside.

"There's a bed here?"

"ah!"

"What are these scissors and knives for?"

"It's for treating external injuries!"

"This is a military camp; soldiers inevitably get injured during training!"

"You used scissors and a kitchen knife to treat your wound?"

"Yes!"

Li Shimin felt as if he had been doused with cold water upon hearing this; his eldest grandson seemed quite unreliable.

"Auntie, please sit down in the chair. I'll examine you in a bit!"

"oh……"

Upon hearing this, Si Zi sat nervously in the chair. Then, Li Jue took out a strange-looking object from the drawer and put it around his neck, and also inserted two silver-white iron rods into his ears.

"Nephew, what's going on..."

"A stethoscope is specifically used to listen to the lungs, heart, and pulse."

Li Shimin was even more disappointed when he saw this thing. Did this grandson not even know how to take a pulse?

"Grandson, don't you know how to take a pulse?"

Li Jue was immediately displeased upon hearing this.

"Uncle Li, do you really think I'm a miracle doctor? I'm just a mediocre doctor, how could I know such advanced stuff!"

As Li Jue spoke, he stuffed the other end of the stethoscope into his aunt's clothes, which drove Old Li crazy again.

"What are you doing? How dare you flirt with your aunt! I'll beat you to death, you unfilial grandson!"

Li Jue finally understood why the first thing doctors did when examining patients was to kick out the family members.

"Uncle Li, I came here to hear my aunt's heartfelt words!"

"Do you understand heart sounds? They're the sounds of the heart beating, used to determine what's wrong with Auntie's heart!"

"Oh oh oh..."

Li Shimin rubbed his hands awkwardly, like a primary school student who had made a mistake.

"Keep watching, I'm not saying anything more..."

"go out!"

Upon hearing this, Li Shimin looked at Li Jue with disbelief.

"You unfilial grandson, what are you saying to me? How dare you tell me to leave?"

"yes!"

"Who told you to always cause trouble!"

"If you don't leave, I won't take my aunt to see a doctor!"

When Li Shimin heard Li Jue say this, he panicked on the spot and quickly took two steps back.

"Okay, okay!"

"I'm leaving, I'm leaving right now..."

Li Shimin, who had returned to the door, was still staring at his daughter with concern. When he saw his eldest grandson reaching his hand into his daughter's clothes, he was so angry that he gritted his teeth.

Hmph!

If you can't cure your aunt, I'll hang you up and beat you!

In fact, Li Jue simply tucked the stethoscope into his collar; the rest was done by Si Zi himself.

Following his nephew's instructions, Si Zi placed the stethoscope on his chest and then looked at Li Jue with anticipation.

"Nephew, is your aunt's illness very serious?"

"Don't speak!"

Si Zi was immediately displeased upon hearing this, but seeing her nephew's serious face and even his furrowed brows, she had no choice but to take it seriously.

After a long time, Li Jue's brows not only failed to relax, but instead became more and more furrowed.

"Auntie, how old are you this year?"

"A little over twelve years old..."

"Your breasts are a bit small..."

"ah?"

Upon hearing this, Si Zi immediately blushed with embarrassment, wishing she could disappear into the ground.

"You...you're here to see a doctor, why are you looking at that area!"

"Auntie, I'm here to treat your illness!"

"It's because of your heart problem that you're malnourished and developing abnormally!"

Malnutrition?

"yes!"

"Although it's impossible for something like this to happen with your aunt's family's circumstances, you have a heart problem and poor blood circulation. Even if you eat well, you can't absorb the nutrients, which is why your breasts are so small..."

Sizi was both ashamed and angry upon hearing this, but she couldn't retaliate, so she could only threaten him with her little fist.

"If you say that again, I won't help you with your homework anymore!"

"Okay, okay, I won't say anything more..."

Next, Li Jue asked some more questions, and finally had Si Zi lie on the bed, pressing on her abdomen, chest and other areas a few times, asking her how she felt.

This made Sizi very panicked. Although she didn't understand what her nephew was doing, she understood one thing: the more complicated the diagnosis and treatment process, the more difficult it would be to cure her illness.

"Nephew, is my illness incurable?"
