On this particular night, at the top of Zhang Menglong's alchemy room, series after series of tribulation thunders appeared. Each manifestation of thunder signified the birth of several Saint Grade elixirs. Moreover, these thunders did not necessarily appear in sequence, and could even appear two or three at a time, or more.
This implied that Zhang Menglong was not just crafting one type of elixir at a time but was simultaneously creating several different types. This notion for the current alchemy rooms was nothing short of a fantasy. If not for Black Mist and Black Meng seeing it with their own eyes, no one would believe someone could have reached such a monstrous level in alchemy.
