How to reduce the manufacturing costs of biochemical beasts, and bring them forward for true use in the civilian world, not just in the world of slaughter.
This was the problem that Mute's father was trying to solve. He was a researcher who worked on decreasing the power of biochemical beasts and their manufacturing costs, wishing to use them in the civilian world. The military didn't attach much importance to this, so he had become a victim of terrorists, who seized the breakthroughs he made in biochemical beasts and took his life.
Eliminating terrorists became the one and only motive of Mute for the past five years. All his efforts had been for the sake of this objective.
Though he clearly knew that Du Zhanpeng had gotten close to him not out of true goodwill and friendship, but just as a way to recruit him, Mute didn't refuse.
As long as he could exact revenge, it didn't matter to him even if he transforms into a demon and fell into hell after he died.
