Zijing, the Evil Monarch, launched a surprise attack on the Primordial Palace, something that nobody anticipated. Not only the guardians of the Primordial Palace, but even the people of the Netherworld World did not expect that after most of them had poured out, Xi Zhao would still order the remaining five people to raid the Primordial Palace. However, it must be said that Xi Zhao's move was akin to a gamble, banking on the guardians of the Primordial Palace joining forces with either the forces of Annihilation Palace or the Myriad Demons Palace. He also wagered that no one would imagine the Netherworld Palace would be so audacious as to be unguarded, leaving behind only two hundred Guardian Puppets.
