The lotus chakra was being forged bit by bit, but the speed was extremely slow. It was not even a fraction of the speed of forging the other chakra meridians.
Even Zhu Wuyang, who had all sorts of advantages in his hands, felt like he was pushing a huge rock up the mountain when he forged the lotus chakra. One could imagine how difficult it was for others to forge the lotus chakra.
It was precisely because of this that even though many people knew that once the lotus chakra was forged, it would be extremely beneficial to a martial artist's comprehension and aptitude, but these people would often give up on forging the lotus chakra.
The reason was simply too difficult and dangerous!
Since forging lotus chakras was not necessary to advance to the Xiantian realm, for safety reasons, why not skip it?
Therefore, many people chose to slack off and save trouble. Even the genius Mad Emperor Zhu Zhenwu had the thought of giving up before he forged the lotus meridian.
