This answer was also what Lin Che had in mind.

The system requires "the emperor's personal belongings" to upgrade, which should mean it needs the emperor's aura.

Jiang Li raised his eyebrows, as if he had figured it out: "Could it be that you used the aura of the royal family to subdue Lei Shi?"

"Well... you could say that. Since His Majesty doesn't want to, then forget it."

Lin Che sighed deeply, "It's just that I'm thinking that this Thunder Lion hasn't been completely tamed yet. It's sometimes very aggressive, and it seems like Prince Wu can still control it. That's why I have this idea, I want to completely tame it..."

As soon as he finished speaking, a roar suddenly came from outside.

roar--

It was the roar of the Thunder Lion, and it slapped into the house on the city wall where Lin Che was.

Boom!

In an instant, the room almost collapsed, with smoke and dust billowing everywhere.

"Your Majesty. Are you alright? Your Majesty!"

Lin Che suddenly stood in front of Jiang Li, looked out from the collapsed gap, and cursed at Lei Shi:

"Lei Shi, you are so brave! Why don't you retreat quickly!"

"Your Majesty, it's a good thing the thunder lion didn't hurt you. Otherwise, I would be guilty of a thousand deaths."

Lin Che looked at Jiang Li's dusty appearance. It was amazing that there was quite a lot of dust in the house.

"Your Majesty, how about this? I'll give the order right away. Have a few female soldiers give you a bath. It just so happens that I have a special medicinal bath that can help Your Majesty quickly recover his true energy."

Jiang Li flicked her sleeves, and immediately there was another cloud of dust. She held her breath and quickly walked out of the collapsed room.

As an emperor, she paid great attention to her appearance.

It is necessary to take a shower and change clothes every day.

But this time, she had been using secret methods to travel all the way from Tiandu City, sweating profusely, and exhausted. She had already felt uncomfortable all over. Now, covered in dust, it was even more unbearable.

"Then go and give the order. I don't need your medicinal bath, I have prepared it myself."

"Very well, Your Majesty, I will do it right away."
