章 703: Key to Breakthrough to the Seventh Level

A trace of Internal Breath circulated in his body at a much slower speed than Chu Nan's normal cultivation. It took a full minute before it finally circulated in the last fine meridian and slowly flowed back to his dantian.

The reason why he was so careful and… slow was because Chu Nan still had to circulate his Internal Breath while maintaining the absorption of the violent spatial energy of the outside world at the same time and continue to maintain the fragile balance between his physical spatial energy resisting the corrosion of the outside world.

Moreover, he was not only cultivating his Internal Breath cultivation method now, but he was also making further improvements and modifications on the foundation of the original Nine Revolutions Technique to prepare to break through to the seventh level.

Seeing that this trace of Internal Breath successfully flowed back to his dantian without any accidents, Chu Nan heaved a sigh of relief.
