However, due to a slight accident, the master accidentally released the demon king. For this, he spent a thousand years in prison and became infamous for a while.

However, due to a little accident, sparks flew between the Celestial Master and the Demon King (?), And they worked hand in hand to find out the truth that had been hidden for many years.
