If he wanted to condense a new one, he probably could only rely on adding points next.
Chi Tong:
Sun Flame, proficient level close to expert level, considered (Proficient+1).
The Interlocking Sword and Spirit Release were both expert level. Moreover, they were both at the intermediate level of expert level. It wasn't as simple as just becoming expert level.
Among them, the reason why the skill proficiency of the Interlocking Sword suddenly increased was because Chi Tong used the "Gemini Silver Armor" as a resource. With the help of its coordination, it quickly pulled up the proficiency of the Interlocking Sword.
As for Spirit Release, it was naturally because it had swallowed a level-eight Death Spirit Treasure Bead.
Susu:
The Wave Cannon and Holy Water Ring were both proficient level, mainly because it controlled expert level water elemental control. Under the lead of this skill, it was easier to train other water-type skills.
