"Are they all dead?"
"They really can't withstand a single blow!"
"It's just that the consumption is a little high…"
The formation slowly dissipated, and a white-robed figure appeared on the spot, muttering to himself.
Although this experiment consumed a total of 10,000 low-grade spirit stones, Ye Xuan did not feel any heartache.
After all, the activation of the formations this time also made Ye Xuan discover many shortcomings.
For example, the eye of the first illusory formation was a little conspicuous and was almost discovered by the black-robed man.
Also, the subsequent formations did not connect smoothly. The "Torrential Rain" and "Fireball" formations were launched at the same time, and the two formations almost fought each other…
Also, the Gale Formation consumed too much energy and the benefits were not high. It was better to pile all the resources on lightning. Perhaps it could instantly kill this group of unlucky people.
