Sharing Cultivation Technique

Now that he faced three immortals and managed to kill them without going all out—unleashing the power of his Heavenly Incarnation—into the battle, Krune became a bit more confident. 

"Next, I should challenge three lone immortals at the peak of the Semi-God Realm," he muttered, looting the residence dry before flying away.

He soon came across a rather famous pair of triplets, known as the Bald Brothers. They cultivated a mysterious technique that required the three of them to cultivate at the same place. 

Only if they had equal cultivation would this work. Otherwise, it would just be a fruitless endeavor, requiring them to cultivate from scratch again. 

Though, from the looks of it, there were obviously significant advantages to this method. In fact, it was the main reason they painstakingly persisted with it to date and even managed to become immortals with it. 

They acted as one!
