Weakness? What is the weakness of a Mechanical Puppet Master? Everyone in the world knows that it's the puppeteer himself! Compared to other cultivators, whether Qi Cultivators, Sword Cultivators, Body Refiners, or Demon Cultivators, all strive to push their personal strength to the extreme in some aspect, whereas Mechanical Mages rely more on external forces.
Although they have their own set of Cultivation Techniques, magic techniques, and talismans for self-protection, because they devote the majority of their life's energy to studying and controlling puppetry, once they abandon their vital puppet, their combat effectiveness plummets. This is why Bai Xuelin was easily subdued by Pei Yan with no capability to resist after regaining his body.
