Master of Kung Fu Vol 1 (1974) #49 Vf
Leiko Wu and Clive Reston enter a silo in Fu Manchu's fortress to find what appears to be a large spacecraft. Alerted, Fu Manchu is confronted by Black Jack Tarr. Tarr doesn't stand a chance and Fu secures the spacecraft. Shang-Chi battles his ancestor Shaka Kharn. It doesn't go well, though he does manage to escape. Fu Manchu and Shaka Kharn take off in the spacecraft just before Larner collapses the mountain, dying in the process.
