Inside the Gravity Room.
Beside a huge mace at the center of the room, Shi Yan was striking it heavily as his body operated Petrification and sweated all over.
That mace was seven meters tall and three meters wide, and was deeply rooted at the center of the stone ground in the Gravity Room. The sharp tips on it were like short rods shining with a dark light.
Shi Yan's body had already turned dark brown and he was breathing heavily. Moving around the mace, he kept slamming into it with his shoulders, arms, waist and thighs.
Endless blunt thunderous sounds came out from the Gravity Room.
To trigger the potential of the Petrification Martial Spirit, one must train themselves in a ruthless way. Only by slamming against hard objects, could the power of Petrification be used to the fullest.
And only by ruthlessly tormenting one's body, could his Petrification Martial Spirit adapt to any kind of attacks.
