As Heng and his team desperately tried to survive, Zheng was causing a storm of chaos inside the alien headquarters... Well, a storm without water, but certainly one with plenty of explosions.
Unlike Heng's cautious approach, Zheng wasn't afraid of the spider robots. Energy beams hardly hurt him; as long as he dodged frequently, his internal energy consumption balanced with his recovery. Therefore, he was fearless against these robots. Once technological weapons proved ineffective, defeating him in close combat was nearly impossible. Moreover, being in the intermediate fourth stage of genetic unlocking and having overcome his inner demons, mental disturbances had minimal effect on him. Only a stronger force or a dire situation could pose a real threat.
