Li Qinghai flew above the ancient river of time.

He didn't pay much attention to the passage of time, estimating that nearly a month had passed.

For so long, he hadn't found the Crystal of Time that Great Emperor Yaofeng mentioned. Where exactly could that thing be found?

As Li Qinghai flew, he pondered and observed his surroundings, not missing any details, hoping to find the so-called Crystal of Time.
