Restraint by the world, Lu Xuan wasn't able to cast more of the laws. Yet, using the law of space solely was already enough—he had already cultivated it to an unfathomable level. As a Celestial Lord in his past life, he must have had an ace up his sleeve. Hence, he had various maneuvers to enhance his skills.
The grumpy old Cambion was no stranger to him. Previously, it had been one of his mortal enemies at this very same stage of his life. Back then, Lu Xuan had just killed the leader of the Xuonhuo Sect when they met. As the Cambions had invaded Earth, Lu Xuan had become the thorn in their flesh, the strongest of the Earthlings. The two sides had engaged in blood-soaked wars until several years later—when Lu Xuan had obtained a Cultivation manuscript for the Immortal Realm. Eventually, he had a breakthrough, reaching the Immortal Realm with all his might, and then he killed the Cambion. Talk about archnemesis.
