Liu Xiong raised his hand, and a jade slip appeared between his fingers. The jade slip was black with silver markings.
"This is a high-level dual cultivation method I obtained before. It can refine two different energy systems without damaging either side. It is suitable for partners with opposing or complementary foundations."
Zhou Lifen's eyes brightened slightly. Fu Seng also looked at the jade slip despite his embarrassment.
Liu Xiong injected his spiritual sense into it, then paused. After reading for a moment, he frowned.
"What is wrong?" Zhou Lifen asked.
"The minimum cultivation required for this method is higher than your current level. You are currently at the peak of Soul Palace realm."
Zhou Lifen was disappointed but not surprised: "How high?"
"Divine Power Realm at least. Preferably the Great Power Realm, otherwise the first circulation route may tear your meridians apart."
Fu Seng said quietly: "It will take years before we're able to use it."
