Immortal killer move — Obscured Heavenly Secret!

Everything happened stealthily.

Only Fang Yuan knew how much immortal essence was used to activate this rank nine killer move.

Three hundred and sixty rank nine immortal essence beads!

After heavenly secret Gu was raised to rank nine, obscured heavenly secret was also finally modified by Fang Yuan, it became a true rank nine killer move.

Compared to the rank eight obscured heavenly secret, the rank nine version used much more immortal essence and the activation time was lengthened to over ten times of before. In addition, the steps were also six times more complicated, and Fang Yuan needed much more thoughts in the process.

After paying such a price, rank nine obscured heavenly secret also became much more powerful!

It was not a quantitative growth but a qualitative change.
