Fang Chen has been reminded about the occupations by the system and that he can learn them before start using the Yin and Yang recovery hands so he immediately started to ask the question about the Yin and Yang Recovery Hands to the system.
"Host to learn about the Yin and Yang recovery hands you should 1st use the ability on the item and find out how you're going to use the Yin and Yang Recovery Hands."
Fang Chen immediately understood what the system was saying So he immediately took out a damaged spirit weapon which was provided by Tian Cai.
The damaged spirit weapon was the sword. As it is one of the easiest weapons to refine so he felt that it would be easier to repair and after putting the sword in front of him he told the system to activate the ability.
