Time Raiders Episode 12

After A Ning abandons the group by triggering a trap, Wu Xie, Fatty, and Professor Zhang are unexpectedly reunited with Zhang Qi Ling, who reveals that A Ning deliberately set them up. Meanwhile, A Ning follows Wu San Xing's trail through the sunken ship and discovers footage suggesting he survived long enough to explore its depths. As the others search for their oxygen tanks, they realize the room has somehow changed, and the tanks have vanished. Suspecting the ship contains hidden moving chambers, the group sets out to find a way through the ever-shifting wreck before their air runs out.
