Xu Ping'an continually unleashed Sword Qi, each strike infused with the mighty fluctuations of Heaven and Earth's forces.
By now, he had reached the late stage of integrating with the Heaven and Earth forces.
Each slash contained powerful tremors of the terrestrial forces.
Such tremors, even if the opponent managed to block his Sword Qi, could transmit the terrifying vibrations into the opponent's body, inflicting severe damage.
The combined combat technique of the four guards before him was decently powerful, but not enough to trouble him.
The only thing causing Xu Ping'an a headache was that group of five successive puppet guards.
These puppets were made from Low Grade Immortal Artifact Grade gold refinement, and every time Xu Ping'an repelled them, they rapidly counterattacked.
Because these puppets felt no pain.
That was the reason Xu Ping'an was being held back.
