Refining an acupoint was a technical task that required meticulousness.
Even if Green Spirit had imparted the method to Junior Leopard for refining acupoints, Junior Leopard could not really understand the difficulty until he did it himself.
He was going to use Internal Qi to scour and expand his tendons and meridians little by little so that he could create another Dantian at that particular point. Thanks to his excellent Inner Vision, Junior Leopard could just barely continue the work. Otherwise, he might have died because of bursting tendons and meridians.
