Lei Dong was deeply tempted by the idea of using soul fusion to control a Golden Core Stage cultivator. But he knew his own limits. He had already fused souls with Qi Feifei once before. If he fused another person's soul into his own, there was a good chance he would lose control of his mind or develop something like a split personality.
That meant the opportunity could only go to one of his other teammates. But the three Foundation Establishment Cultivators had relatively weak souls. Even if they tried to control just a wisp of a Golden Core Cultivator's soul, they might not be able to subdue it, and the chance of suffering a backlash would be high. Only Qian Luo was capable of ensuring Black Iron Tower had no chance to turn the tables while their souls were fused.
At the mention of soul fusion, Black Iron Tower drew in a sharp breath. He hadn't even escaped the wolf's den, and now he'd fallen straight into the tiger's jaws. A trace of anger crossed his dark face. "Brother Lei, if you use soul magic to control me, I will never surrender. I'd rather die in battle than lose my freedom again."
"Black Iron Tower." Lei Dong looked at him seriously, his expression solemn. "I can make you a promise. If you serve me loyally for twenty years, I'll set you free and return that wisp of your soul. After that, you can go wherever you want. You also heard Tantai Bingyun say just now that she has a way to resolve the Ghost Gu. Give me twenty years, and you'll have your freedom back completely. That's not an unreasonable deal, is it? We'll solve your Ghost Gu problem, and you should be grateful I spared your life, too."
