In his previous life, the monster civilization had Nine Great Supernatural Entities.
Among the nine, there was most likely one known as the monsters' mastermind, and it could even die together with Battle God Lei Zongchao.
After returning from the apocalypse, Meng Chao witnessed just how strong the White Spirit, Earthquake, Demonic Abyss Eye, and Vortex were.
What about the other five?
Of course, Meng Chao believed that his return had disrupted the rhythm of the monster civilization's development, and the remaining five of the Supernatural Entities definitely had yet to evolve to their full form just yet. They were not as mysterious and powerful as the ones in his previous life.
However, during the pitched battle, the monster civilization had decided to stake everything, and regardless of how far along the modifications of the remaining five Supernatural Entities were, they should have joined the battle.
