For Su Chen, he had three objectives for this mission. The first, and most important, was to destroy the Skull Society, especially Tang Gang's experimental base.
The second goal was to force out the forces behind Tang Gang. Always being watched without knowing anything about who was behind him made him feel very uncomfortable, not to mention dangerous!
Punishing Tang Gang for his betrayal had become the least of Su Chen's concerns at this point, essentially the third and final goal.
Of course, Su Chen was no saint and wouldn't completely ignore past betrayals, so he was determined to do what needed to be done!
After boarding the plane, Su Chen opened the case and took out the Almighty Bone Marrow, which Dr. Gaia and his team had developed, along with dozens of large syringes to explain to everyone.
These syringes were of course meant for injecting the Almighty Bone Marrow into the Gene Modifiers.
