Chapter 685: Boss Ultimate Move

This dragon-slaying sword energy was slashed out by the Frost-Flame Edge, with golden sword light as the main body.

One side burned with orange-red flames, and the other side was as cold as frost!

The two-attribute damage bonus made the power of this Dragon-Slaying Formula extremely tyrannical.

Moreover, this boss was of the Giant race, with a huge figure, so it naturally triggered the 【Killing Jiao Strength】 affix of the Dragon-Slaying True Formula, and its power increased suddenly.

Coupled with the extra sword energy of the 【Drunken Sword Style】, two whole large sword energies flew out!
