Tome of Poison Legacy

The headquarters of the Poison Hall was located amid a massive mountain range. Unlike the other branches, which were concealed by formations, it was an enormous city that extended for several thousand kilometers, exposed in the open.

It had an economy of its own, producing and selling its own resources, reminiscent of a mini kingdom.

Upon seeing the majestic city before his eyes, Bai Ting couldn't help but remark, "It is said that vast majority of the mountain range has been laced with lethal poison, and any personnel who isn't a poison master of the Poison Hall would be swiftly poisoned to death. As such, there is no need for the headquarters to conceal itself from the eyes of the world at all."

The Poison Hall was a feared existence throughout the Master Teacher Continent. Thus, for safety considerations, most branches were concealed within a formation so that the other occupations would not be able to find it.
