Although the energy required to rise from a One-star Dou Sheng to a Two-star Dou Sheng was greater than that needed for an Advanced Half-Saint to break through to One-star Dou Sheng,
the difficulty involved was vastly different. Taking that step into sainthood was not merely a matter of accumulating energy; it involved many factors, and the bottleneck was extremely difficult to overcome.
That was why Flowing Cloud had chosen to fuse his soul with his physical body only after his clone's Soul Power reached the late Heaven Realm. That would allow him to break through that bottleneck.
After that, before reaching Four-star Dou Sheng, as long as enough energy was accumulated, consecutive breakthroughs would not be a problem. Of course, this only applied to Flowing Cloud's clone. Since the clone was linked to the main body, such rapid advancement would not have much of an impact. Others who had never experienced such circumstances could not possibly advance so ferociously.
It was like the current Yellow Springs Demon Saint. He had once reached this realm, and now he merely lacked strength. Once that missing strength was replenished, he could rapidly rise again.
Refining a clone followed the same principle as Yellow Springs Demon Saint recovering from his injuries. There were not many bottlenecks.
It was only because the clone Flowing Cloud had refined this time possessed attributes different from his main body that the difficulty was somewhat greater. If Flowing Cloud had continued refining a clone with fire and wood attributes, the speed would have been more than twice as fast.
"Next, let's continue improving!"
Flowing Cloud once again took out a huge pile of treasures that could stir up a bloody storm across the Central Plains and refined them with his Life Fire. The wild energy that even Dou
