The pitch darkness in the cave was such that it seemed as if there was nothing in the air.
Suddenly, the dark bullet flew straight towards Fang Yun.
Fang Yun was startled by this scene, but he still stood his ground calmly.
Apart from sensing that the spirituality within the black bullet had no malice, Fang Yun also discovered that it was made almost entirely of energy and lacked the material form that the Spiritual Insect once had.
This led Fang Yun to some guesses about the bullet's behavior.
Sure enough, as the bullet collided with Fang Yun, it entered his body in an instant.
It entered his body like a fish returning to the sea, causing no harm to anything within Fang Yun's body.
Instead, it moved through his body as if it were part of him, easily navigating through his meridians.
After traveling through Fang Yun's meridians for a while, by evening it entered into his Lower Dantian.
