Chapter 643: Jian Wushuang Versus Gong Chao

Boom!

The sound of the initial confrontation was loud enough to shake the entire area.

The whole battlefield was a surging storm of power.

All the spectators were shocked.

After all, there was a wide gap between Rank One Secret Skills and Rank Two Secret Skills.

Many geniuses were able to invent Superior Rank One Secret Skills. Each of the geniuses who made it through to the third round of the arena duels had created their own Superior Rank One Secret Skills, but the power of their skills was different and no one had displayed a Rank Two Secret Skill because it was much harder to create Rank Two Secret Skills.

A genius, who wanted to create a Rank Two Secret Skill, should have a high understanding of the Dao, especially the Weapon Dao.

For example, a genius might be able to invent a Rank Two Secret Skill, if he was adept at spear techniques and had done an in-depth study of the Spear Principle.
