Late at night, in the room where Xu Nian stayed.
Xu Nian didn't fall asleep peacefully, but instead entered into arduous training.
After exchanging punches with that Nine-star Star Realm Body Cultivator today, he clearly felt how the iron hammer influenced his strength.
At this moment, Xu Nian, with the iron hammer on his back, supported himself on one hand on the floor, standing upside down in the room.
Veins popped out all over his body, his muscles swelled up like a cage, and powerful Gang Qi roamed within him, moving beneath his skin like a mouse scurrying back and forth.
Xu Nian's face reddened, drenched in sweat, obviously struggling to maintain such a pose, but he gritted his teeth and persevered.
Every second of this upside-down stance was incredibly difficult; during this process, he had to absorb Gang Qi through every cell in his body, and ultimately concentrate it all in his arms to maintain his balance.
