Eighteen Years

Within the vast, seemingly endless Great Canyon, Xue Ying, clothed in white robes, was currently examining the blade scar left behind on the cliff before him.

"I really wonder if I can attain this realm in my lifetime." Xue Ying continued analyzing the blade scar, mumbling to himself. Soon after, his body began trembling. Taking out the black wine flask, he gulped down the antidote within, reducing the pain as the concoction coursed through his body. "Previously, I had to take the antidote once every half an hour. Now, it’s twice the frequency."

"A year has passed outside, but within the Great Canyon, I’ve been here for eighteen years." Xue Ying sighed.

Eighteen years.

He had seen every single scar left behind in the Great Canyon, personally observing and imitating its creation. In the end, he kept returning to this specific blade scar, with more than half his time spent pondering over this and the Laws of Profound Mysteries hidden within.
