Chapter One Hundred and Fifty-Five: Unable to Restrain

Chen Li sat in a tub filled with medicinal herbs, his eyes slightly closed, his body red hot, and wisps of green smoke rising from the top of his head.

In his inner vision.

As spiritual power continually refined him according to the Immortal Muscles Jade Bones Skill, it seemed as though countless intricate patterns appeared on his crystalline bones, flickering in and out of sight, shimmering as if they were breathing.

Since he began cultivating the Immortal Muscles Jade Bones Skill now a year and a half ago, he had spent over ten top-grade Spirit Stones on it.

Meanwhile, the Immortal Muscles Jade Bones Skill had also slowly advanced to the expert level.

Compared with the initial stage, the route of the Immortal Muscles Jade Bones Skill had become more complex, and these dense patterns on the bones only appeared after the Cultivation Technique advanced to the expert level.

The result was... a significantly increased consumption of spiritual power.
