What should I do if my junior brother becomes a bad old man?

I have a younger brother.He ran away from the mountain at the age of 15, and has not returned for 80 years.Although people who cultivate the Tao live a long life, I still thought I would never see him again.Unexpectedly, he came back recently.And...he turned into a bad old man.Copywriting for the junior version: I had a crush on my senior brother for a long time, and knowing that he couldn't respond, I left the mountain.It was not until now that I was getting old that I thought about seeing my brother again for the last time.Unexpectedly, in order to help me, he not only obtained the world's most precious Nanming Pearl, but also captured a dragon.So... my senior brother is a big boss?The face is tender and the heart is ruthless, the ten thousand-year-old monster brother Gong x Although he looks old, he is still younger than the senior brother anyway. :
