An Earth-level Elixir was a treasure beyond estimation, and among these, the Pill of Tribulation was an even rarer and precious elixir. This was mainly due to the rarity of the ingredients required for its concoction, and the alchemy prescription for the Pill of Tribulation was extremely scarce, almost lost to time. The prescription was only recorded in the Supreme Elixir Canon inherited by Su Chengyu.
Even though the concoction of the Pill of Tribulation was difficult and the ingredients hard to find, these were not the main issues. The main issue was this elixir offered little benefits for cultivation, it had a relatively niche use.
It was said that within the far north Dark Sea, there wasn't just formidable beasts, but also a tribe of aborigines known as the Nether Clan.
Members of Nether Clan rarely left the Dark Sea. They looked different from humans and were far from ordinary, having managed to survive in such harsh environments.
