Immortal Sword Body!
The Immortal Sword Body required repeated tempering. Only by polishing it to its absolute limit could one achieve a breakthrough.
Especially since Jiang Chen himself cultivated the Divine Demon Tyrant Body, his physical foundation was on par with, if not superior to, that of an ordinary Human King Realm Powerhouse. To advance his Immortal Sword Body at this stage, he had to endure a trial of a thousand temperings.
The appearance of Master Ouyang was the perfect opportunity!
By using Master Ouyang's relentless attacks to temper himself, the instability from Jiang Chen's rapid breakthroughs was completely worn away.
His physical body had grown even more solid!
Moreover, the epiphany he'd had during the Spirit Rain allowed him to grasp the key to perfectly fusing the Four Great Secrets of Earth, Fire, Water, and Wind.
He had already reached the critical point of a breakthrough.
