Heroes' Prison has existed since the Era of the Ancient Gods, and within it were confined exceptional beings from generation upon generation. After death, their bodies were all collected into a morgue, accumulating together. These exceptional beings had incredibly strong bodies, and given the unusual area of Heroes' Prison, they would not rot! Some materials from magical beasts might have already gone extinct in the outside world, but could still be found within the confines of Heroes' Prison!
How powerful would external incarnations be if made from the materials of these strong beings? It's estimated that no one from ancient times to today has ever undertaken such an enormous task! Although an incarnation only possessed 50% of Huang Yi's strength, the intrinsic abilities of each material component on its body were not so limited, and just these myriad abilities alone were terrifying enough!
