For an entire afternoon, he initially completed one round of marrow cleansing, which took nearly two hours.
For two hours, he continuously wielded the blade, drawing the power of heaven and earth into his body, only then could he perform one marrow refining.
Now, due to increased proficiency, the time required to complete one round of marrow cleansing has been greatly reduced, cut by nearly half.
Now it only takes a little more than an hour for him to complete one marrow refining.
At this moment.
Because he was frequently cleansed by the power of heaven and earth.
In the fading twilight as the sun slowly set, under dim light conditions.
The residual glow on Jiang Ning's body was even more apparent.
It also seemed incredibly sacred, like an immortal.
"It counts as entering the ranks of the Fourth Grade!" A smile appeared on his face.
In an afternoon, he completed marrow refining six to seven times.
