Seeing his attempt failed, Alex analyzed the reason by observing the transparent barrier.
"Hmm…It's like an array that will stop any physical things from entering. In that case, it means I am not required to face all these ceilings that will drop to me. And since I am sealing my power to only a Martial Saint, I won't be able to pass the speed of the drop.
"In that case, there is something more to this challenge. The problem is what kind of thing I need to send to hit that red button." Alex narrowed his eyes. "Since physical won't work, I guess Spiritual Energy or something?"
When Alex thought about this, he suddenly figured it out.
He raised his hand and waved it to the front, sending a wisp of Spiritual Energy. To his surprise, the ceiling went down again, blocking the Spiritual Energy from passing it.
