*Clang!*
"It's too damn hard." Theo clicked his tongue. He also applied the Invisible Vortex in his attack so that the shock wave hit the dragon's body.
However, the hardness of this body seemed to be distributed easily. The shock wave ended up doing nothing and getting reflected to the ground.
Instead of pushing back the dragon, the shock wave created a small crack on the mountain's surface. Luckily, it wasn't strong enough because no one knew if there was a magma beneath it or not.
Even Isaac couldn't help but say, "Don't do too much damage, Joker. Although the mountain should have a thick skin on the surface, there might be a small crack that will bring out the magma. I'm afraid the dragon can become stronger with magma, so don't hit the ground."
"I'm trying." Theo gritted his teeth and jumped away before the other heads attacked him.
As expected, fighting against a Mythical Rank Creature wasn't easy.
