Fusion of the divine daos had always been an extremely difficult task.
Back then, Luo Zheng had already spent considerable effort fusing three hundred divine daos. Three thousand divine daos raised the difficulty by an entire order of magnitude—the challenge of fusing them was clear.
Among three thousand divine daos, as long as even one could not meld with the others, the Dao Fusion Energy would run out of control.
Once out of control, the Dao Fusion Energy would produce violent fluctuations. If it could not be controlled properly, it would explode.
