Zhang Yu gazed at the new layer effect of Qi Vein Flow, his eyes slightly narrowed, and he decided to give it a try right away.
Zhang Yu's mana circulated within him, transforming into bursts of Formless Cloud Gang rising from his Dantian.
The next moment, the rolling Gang Qi had already transformed into three Formless Warriors, which emerged behind him.
Accompanied by the punches and kicks of these three Formless Warriors, they practiced various martial arts Zhang Yu had mastered, depleting his mana dramatically.
But Zhang Yu felt that, under the effect of this new layer of Qi Vein Flow, the speed of mana consumption was significantly lower than before.
Zhang Yu mused, "During the process of mana circulation, there will inevitably be extra wastage. With Gang Qi operating outside the body, the wastage is even more."
"However, with the added effect of this layer of Qi Vein Flow, wastage is reduced, which means my mana is more durable."
