Sakata Norio was puzzled, but Shen Yue was well aware of what was happening. By standing and applying pressure next to the base for a long time, he had managed to use hydraulics to open a passage.
The passage, made of metal, was narrow but extremely long. In the short time they had been sliding, they had already traveled several hundred meters, and during this time, they also passed through some hollow layers.
These hollow layers seemed to be artificially excavated.
As soon as he slid out from the pipe, Shen Yue had already removed the force of descent and floated down lightly. At the same time, a full panorama of the places he had passed flashed through his mind.
The cave entrance behind the Feilai Peak waterfall was an entrance to this place.
