Capítulo 214: Burial God's Sanctum Part 15

Suddenly, this thought rang on his mind. Weapon Master, a especial cultivator that can use all kinds of weapon with perfection. The power of his attacks comes from his strength, not weapon. But he can manipulate any kinds of weapon he wants, succeeding in different methods like sneak attack, using overpowered weapon without restriction.

This is why cultivator doesn't choose a single weapon most of them. If they have Earth Rank Sword but unintentionally they find Heaven Rank Spear, they won't take time to change the weapon. Not just in weapon, but also in battle arts.

If you have a Earth Rank Sword Art and a Heaven Rank Spear Art, if that person isn't someone like Klink, he would definitely choose Heaven Rank Spear Art. Because that's Heaven Ran. This is also why Supreme Sword Sect was able to invite other sect for grand competition.
