"Kid, I'll go to the mortal world with you."
…
Immortal Lord Zi Yu and the others were originally hesitant about Han Muye leaving the Immortal Burial City.
However, when they saw the spirit sword behind Han Muye, their expressions changed.
"You want to temper yourself in the mortal world and then…" Immortal Lord Zi Yu looked at Han Muye.
Han Muye nodded.
This reason was very real.
To subdue such a spirit sword, one needed to truly experience the mortal world with it.
In the opinion of the Immortal Lords, Han Muye wanted to leave the Immortal Burial City to obtain the recognition of Spirit Sword Golden Immortal.
This could explain it clearly.
Even Immortal Lords like them were willing to spend thousands of years for this spirit sword.
