Chương 703: Immovable Foundation Seal

Xu Cheng retreated backwards as his eyes flashed with a grim expression.

Although it was merely a single exchange of blows, his arms had already gone numb and his blood qi was fluctuating wildly.

However, Su Zimo wielded Blood Quencher and charged over as though he was completely unaffected!

"I can't fight him head-on anymore!"

Xu Cheng made up his mind decisively and gripped his Green Thunder Saber with one hand. His other hand conjured a hand seal before eventually releasing a spirit art that burst forth immediately!

"Zephyr Thunder Break!"

Xu Cheng hollered.

A wild wind gusted and fluttered towards Su Zimo - sand was already flying everywhere before it arrived!

In the wild wind, there was even a sizzling green lightning that looked extremely horrifying!

Xu Cheng also released the sound secret killing move of Zephyr Thunder Palace through his voice.
