Jiang Yuan can only use the abilities he possesses.
However, One Qi to Three Pure Ones is different. The abilities Jiang Yuan doesn't have can also be used after learning them.
For example, Jiang Yuan doesn't practice martial arts and doesn't use other types of cards much; he's relatively lazy.
But the clone can go learn and use other types of cards.
The point is, what the clone learns can be fed back to Jiang Yuan's main body later on.
This is why Tongtian Sect Leader's Execution of Immortals Sword Formation can only be broken by the Four Saints, yet the Old Lord can hold it off by himself.
The Old Lord can do the work of four people alone!
Is this the strength of One Qi to Three Pure Ones!
But the problem is, if this skill were to be made into a Skill Card, Jiang Yuan has no idea where to start.
He can only wait for the Old Lord's skill to be unlocked.
But the problem is, how exactly is this skill of the Old Lord supposed to be unlocked?
