Ethan Smith tried every technique he knew, but he still couldn't budge this ancient door.
This ancient door exuded an unassuming vibe, and it was unclear what it was made of, but its hardness was unparalleled, making even Black Gold Stone pale in comparison.
"Perhaps...there's a hidden mechanism here to open this door?" Ethan Smith thought to himself.
He immediately released his divine sense and began an extensive search, hoping to find the mechanism controlling the door.
Unfortunately, he spent an entire day searching, but still couldn't find any such mechanisms.
This couldn't help but make Ethan Smith worry.
Would he be trapped here for the rest of his life?
"Forget it." After pondering for a long time, Ethan Smith ultimately decided to retreat and cultivate, swallowing those inner cores.
If his strength was strong enough, perhaps he could break through this door.
