Downstream from where they were standing.
In a far distance.
A large houseboat was sailing up at top speed.
It seemed like a magical boat, with never-ending thrust power.
It was cut through big waves while traversing at top speed.
A beautiful melody could be heard from the boat. There were drums and bells.
A subtle tune.
Classical and light-hearted.
It made them feel refreshed and energized.
In a blink of an eye, it was already much closer to them.
The elder looked astonished, "Well, young master, you were right about this boat! It is a trick of an ancient almighty being!".
The young practitioner squinted his eyes to look at the boat, "A welcoming vessel, it could only be conjured by someone above the level of a Great Saint. This ancient relic is remarkable! It's from the previous era!".
