Massive Debt
Gnyan spent seven days in the dark cell and all this while, he is screaming at the top of his lungs demanding a meeting with his father, but his father already seemed to have instructed him to not bring anything related to his disappointing son to his notice for these seven days.
On the seventh day, he was finally able to get a meal but as soon as he ate it he fell unconscious and his spiritual energy that was locked couldn't help.
Now this news was finally brought to his father's notice and the family healer took a look at him and said some absurd reason that they sounded stupid.
"He ate food that was too good. He was served spiritual cuisine while his cultivation is locked. It was too much load for the body and he fainted. Unlock the seal, bit by bit, and let him absorb the energy slowly and he would wake up. Don't take it off immediately; that would be too much overflow of spiritual energy to his body as he wouldn't be awake to control it.
