You are asked to be a good grandson, but you raise a group of banshees?

Description

Lu Yuan traveled to an alien version of the Ming Dynasty.
Here is Emperor Yongle, here is the Crown Prince, the King of Han, and the King of Zhao.
Emperor Yongle was Lu Yuan's grandfather, but Lu Yuan was not a good grandson of Emperor Yongle.
He is the eldest son of the King of Han.
Looking at this foreign dynasty that was similar to the Ming Dynasty in every aspect, I took another look at the truly good saint grandson.
Lu Yuan thought about Hanwang BBQ and his entire family being wiped out.
However, if you encounter an opportunity and help the monster, you can get a reward.
【Jade dragon asks for seal】
[Option 1: Seal the Dragon, get reward: Dragon Body, "Ingenuity"]
[Option 2: Seal the snake, no reward]
Eh?
Why does this thing only have one option?
Many years later.
Emperor Yongle: "Yuan'er is my great saint grandson!"
