Douluo: I Am the Puppet Master

[Newbie is on the road, please forgive me for the bad writing] When a puppet master suddenly appears in Douluo Continent, what kind of disturbance will be caused in the continent? Why did a level 95 titled Douluo kill his teammates? Is it the distortion of human nature or the loss of morality? Tang Yu calmly put away the puppet string: Do you believe me when I say I didn't do it? That day, soul masters across the continent remembered the fear of being dominated by puppets. PS: This is my first time writing a novel, so readers please understand if there are any shortcomings.
