Chương 451: Upgrade, to the South

The first thing was to cultivate Profound Yellow Battle Body.

This technique had been advanced to the 7th level by Mo Xiu, allowing him to gain a 128-fold increase in combat power in a short period of time.

Mo Xiu had seen similar techniques in the past, and the most powerful one was that one could obtain a 128-fold increase in combat power. He had never seen a higher-fold increase in combat power in a short period of time.

That was why the Profound Yellow Battle Body was really not an ordinary powerful technique.

However, the last few levels of the Profound Yellow Battle Body were really difficult to cultivate.

Even if Mo Xiu thought that his understanding of the Profound Yellow Battle Body was no less than that of anyone who had cultivated this method in the past, he still dared not say that he would be able to cultivate to the ultimate, which was the 9th level.

Not to mention the 9th level, even the 8th level was very difficult.
