At an unknown point in time, Martin was among the students taken under Yang's teachings, with Yang becoming infamous for his strict methods on him. However, when Yang tried to use the Yin Blade on himself, he accidentally cursed the Temple of Airjitzu, transforming himself and his students into ghosts. At some point after that, Yang used the Yin Blade to enslave them to his will.
As the morning came and the curse on Yang's Temple started to take effect on the Ninja, Yang showed himself, revealing Martin and the other students to be chained up, as they were imprisoned by Yang. The Ninja then quickly fled to the entrance, not wanting to suffer the same fate as Martin and the other students. They managed to reach the entrance, but Cole dropped the scroll mid-way and thus had to go back in to retrieve it, which caused him to turn into a ghost. Fortunately, he was able to escape the temple before he could meet the same fate as the students.
After Yang's temple was torn out of Ninjago to help construct Djinjago, Martin and the others left Yang's temple while Yang angrily confronts Nadakhan, claiming domain. However, the latter, unimpressed, promptly ordered Dogshank to shoot water at the students, forcing them to abandon the temple.
With Cole restrained, Yang has his students watch him while he opens the Rift of Return. However, Cole attacked them and went after Yang. The students went outside to watch and jumped through once the portal opened to become mortal again.
