The other people weren't much slower than Rean's group when it came to cultivating, though. Then again, it's not because Rean and the others were not fast, but because they needed a lot less Divine Origin Energy to achieve their breakthroughs. If one also counted the amount of Divine Origin Energy that the twins absorbed, then they were definitely much faster. That's why quite a few had broken through a similar number of stages as the twins.
Of course, that also made a few of them perplexed as they could see that Rean's group was absorbing more Divine Energy than them. Even with all that energy, they were still at the same pace. Some thought that it was possibly because of a bad cultivation technique, while others simply thought they were holding back on purpose.
In any case, the twins' group didn't care. They continued with their ridiculous absorption of Divine Origin Energy. In fact, Rean was right in the end.
