Su Yang now needed to use the Power of Earth to envelop the Heaven Slayer. If he couldn't gather enough power at once, he would have to gather the Power of Earth again. In this process, the Heaven Slayer would have to resist the Power of Earth, which posed a risk of injury.
Another issue was that if Su Yang gathered too much power at once, it would lead to another extreme situation. That is, the Power of Earth would be stronger than the Heaven Slayer's power, leaving him vulnerable and heavily damaged by the Power of Earth.
Therefore, the most troublesome aspect of bringing the Strongest into this place was how to gather enough Power of Earth at once.
Previously, Su Yang brought many people inside because he was at the Peak of Earth-level, his strength either matched or was significantly stronger than those people. This way, Su Yang could estimate how much Power of Earth was appropriate based on his power.
