Zhang Chi was mulling something over, but what it was, no one knew, and to coordinate with his plans, everyone began to take action.
The first step was to manipulate the Spirit Cauldron to create a small opening in the Guardian Great Array, an opening that would let in the Gray Mist but not affect the overall Array.
This was no small feat and could only be achieved by activating the four Immortal Cauldrons.
There are five Immortal Cauldrons in total, among which the Central Qilin Cauldron should not be moved; to create a small opening, the four other cauldrons were sufficient.
Jin Ling'er and others each controlled an Immortal Cauldron to activate the Array, and since Zhang Chi, as the inheritor of the Red Cauldron, had to take part in negotiations, he let Cai Yu take his place instead.
Conveniently, Cai Yu was a Phoenix and could produce fire, so the Red Cauldron recognized her and therefore, triggering the Array was not difficult.
