Lin Feng understood what Longbetham meant.
He had been cultivating the Bemond Mental Guidance Technique recently. His mental power exploded continuously, and its growth was indeed very fast. The original Mental Power Sphere had almost expanded by two or three times.
However, he also seemed to have reached his limit at the moment. No matter how it exploded, his mental power grew very slowly.
This was the limit. If one could not break through to the second level of the Mental Guidance Technique, one could forget about undergoing a life transition. Even if one's life could undergo a second transition, without the guidance of mental power, one could forget about cultivating a combat body.
He must attain a breakthrough in mental power to the second level of the Mental Guidance Technique. Only then would he have enough mental power to guide the restructuring of his genes and cultivate the combat body.
