Enveloping Zhou ZiYi with Mana, Fang Cheng didn't exert much effort and directly entered the interior of the battleship.
While passing through the outer section of the battleship, Zhou ZiYi was visibly very tense.
He knew that with the Great Heavenly Lord by his side, he would definitely not encounter any trouble, but when he saw the energy fluctuations emanating from the battleship, he still felt a strong sense of alarm and shock.
The Tai Qing Thunder Pool Cannons had been created to serve in large-scale wars, and when not activated, they emitted virtually no Mana fluctuations.
But once they began charging, the stored Spiritual Energy would in an instant fill the Tai Qing Thunder Pool Cannons, then condense the Mana inside to the limit before firing.
There was almost nothing that could withstand such an attack, and during the charging, the buzzing sound of thunder would be incessant, like the Underworld's soul-reaping judge, walking towards its target with a bell in hand.
