An ultimate warrior, the one and only Alchemy Emperor, Ling Han, had died in his quest to achieve godhood. Ten thousands years later, and he, with the "Invincible Heaven Scroll", was reborn in the body of a young man with the same name. From then on, winds and clouds moved, as he set himself against uncountable geniuses of this new era. His path of becoming a legend has begun once more. At all eras, and underneath the heavens, I am the strongest!
Ling Han circulated the Indestructible Heaven's Scroll, and reformed his Godly bones.
Destruction followed by construction was a tempering and a qualitative boost.
However, this process was really not an enjoyable experience.
Ling Han obviously possessed the Indestructible True Fluid, but he could not use it now, because he needed to allow his Godly bones be tempered by the heavenly tribulation to wash away the impurities within. Only with that could his physique advance towards the level of Level Two Godly metal.
This caused him so much pain that he wanted to die.
Temporarily existing without one's body was only possible when one had reached a cultivation level as high as his and had a strong spirit. Otherwise, if it had been an ordinary human being, the body being shattered would have naturally led to definite death.
