Secret technique cultivation!

Ye chen brought han Lingyu and the purple-robed youth out of the immortal stairway and arrived at a cave.

The space in this cave was really narrow, so ye Chen's attack widened the cave a lot with a loud rumble.

Ye chen entered the cave and sat down cross-legged.

Han Lingyu and the purple-robed young man waited outside. They knew very well that ye Chen's breakthrough would cause a huge commotion. They were too close to him and could not withstand such a strong force.

After ye chen sat down cross-legged, he took out a storage ring which contained all the celestial stones he had.

Most of them were low-grade immortal stones, and only a few were middle-grade immortal stones.

However, a middle-grade immortal stone was many times more precious than a low-grade immortal stone.

The middle-grade immortal stones were extremely precious. One of them was equivalent to ten low-grade immortal stones.
