Time Raiders Episode 2

Before setting out, Wu Xie recruits Pan Zi and Da Kui to join the expedition led by Wu San Xing. During the journey, he meets a mysterious, black-clad young man carrying a sword case, whose quiet demeanor and the respect shown to him by Wu San Xing leave a strong impression. After reaching the end of the road, the group travels by boat through a dark underground waterway. As they venture deeper into the cave, the boatman and guide mysteriously disappear, leaving them trapped. The group is soon attacked by flesh-eating corpse beetles, but the mysterious stranger swiftly dispatches the creatures. Chaos erupts when a piercing sound capsizes the boat, throwing everyone into the water. Wu Xie risks his life to save Pan Zi from a corpse beetle, and Pan Zi returns the favor by rescuing Wu Xie from another deadly attack.
