Setting up the Array wasn't difficult for Jiang Zuo. The hard part was all the extra things he added.
On top of that, he had to resolve the issue on the Elemental Level.
That made it even more troublesome.
In truth, using the Celestial Tribulation to intimidate the Elemental Spirits didn't have a high chance of success.
But if they were all as cowardly as the Water Elemental Spirit, the odds of success would be much higher.
Even ownerless Elemental Spirits would take real damage if they were caught in the lightning of the tribulation.
A scared one would probably flee. As for whether it would die, that was hard to say.
This was the first time Jiang Zuo had ever tried something like this.
It was late at night by the time Jiang Zuo finished the Array.
He had already inspected it and found no issues.
