Busby's goal was not to kill Lin Huang but to catch him alive.
As the Queen Mother's Bug Servant, he knew very well that to breed Ultimate Elites, the material had to be a living person.
Although the Queen Mother could breed Bug Tribe descendants through all kinds of dead bodies, compared to breeding with a living person, the memory and inheritance left behind would be limited. It was also quite impossible to breed Ultimate Elites via that method.
To Busby, Lin Huang was undoubtedly the best breeding material in the entire gravel world.
Although he was enraged that his identity had been exposed, he had never thought of killing Lin Huang. Since all he needed to do was to capture him alive and bring him to the Queen Mother for breeding, the secret would naturally die with him.
His attack seemed quick and ruthless, but it was meticulous. It was done just to capture Lin Huang.
