Tantai Xuan sealed the netherworld.
It was silent. Not many people in the entire five phoenixes knew about it. This was because Tantai Xuan only sealed the path for outsiders to enter the netherworld. If any living creature died, their souls would still be drawn to the netherworld, it didn't affect the operation of the five Phoenixes realm.
Hence, it didn't cause too much commotion.
After sealing the underworld, Tantai Xuan walked in the underworld. He wanted to forge his own emperor weapon.
Emperor weapon was actually a golden immortal. It was an important means to increase the combat strength of the Emperor Realm.
It was like facing the golden spear that was thrown out from the void crack. If they had an emperor weapon to defend against it, they would not be so passive.
And refining an emperor weapon was not that easy.
After all, an emperor weapon needed to communicate with the Heavenly Dao and contain the power of the Heavenly Dao.
