Five Elements Tribulation (1)
The Huaman Multiverse's clone was busy searching for the embryonic form of the universal passage, and then placing the timed Barrier-Breaking Stones into the embryonic form of the universal passage.
When Zhu Wuyang was about to leave, these Barrier-Breaking Stones would detonate and completely destroy the embryonic form of these universe passages, making them impossible to open in the future.
The Barrier-Breaking Stone was the harvest of Zhu Wuwan's decades of hard work. It could effectively destroy the embryonic form of the universe passageway. After many improvements, only one Barrier-Breaking Stone was needed to destroy the embryonic form of a universe passageway, and it would never be opened again.
The opening of the universe passageway usually took a long time, at least dozens of years or more, or even longer, so it was enough for Zhu Wuyang to prepare.
