The ultimate thing behind the bronze door is the origin fragments of countless worlds. These fragments are not stable. Once they erupt, they will threaten the entire world. Someone needs to clean them up regularly. As a reward, everyone who cleans up the fragments can have some special abilities, such as pseudo-immortality, powerful abilities, and artifacts similar to the Ghost Seal!
During the Republic of China, the Zhang family, which had been guarding the Bronze Gate, suffered from civil strife. As a result, the family's power was greatly reduced and they were unable to guard the Bronze Gate alone. As a last resort, the Zhang family sought help from the Nine Gates and exchanged interest for the nine gates to guard the Bronze Gate together!
It was just that none of the nine gates kept their promise to guard the bronze door afterwards, resulting in the debris behind the bronze door not being cleaned up in time, and eventually erupting directly!
The people in the Nine Sects made timely remedies. The nine heads of the family suppressed the Bronze Gate with their bodies at the same time, and the Zhang family members also suppressed it with their own bodies. They finally turned the tide and turned the fragments into 'copies'. If the person who enters can successfully meet the conditions and get the key items to pass the level, the fragment will dissipate and its power will be integrated into the origin of the world, making the inside and outside balance and peace. If it fails, the fragment will explode, and the dangers in it will randomly appear in the real world!
Intention: The world is never peaceful, it's just that some people carry a heavy burden and move forward.
