While astonished by the unknown power, the Celestial Doctor also felt a deep dread toward the original body of this vessel.
Thus, taking advantage of Xuanyuan Tuo's severe injuries and his unconscious state, the Celestial Doctor began to tamper gradually with his body.
The Celestial Doctor knew that Xuanyuan Tuo was under the protection of that mysterious murmuring force. Therefore, he did not resort to ordinary methods but instead relied solely on the [Heavenly Soul Reincarnation] technique, which forged a connection between the two dual souls, using himself as the medium to slowly infiltrate.
In some sense, he was Xuanyuan Tuo, and Xuanyuan Tuo was him. However, due to the mysterious power enveloping the Xuanyuan Clan's bloodline, Xuanyuan Tuo, who was supposed to lose his independent consciousness, still managed to retain control over his body.
The stronger Xuanyuan Tuo grew, the stronger the Celestial Doctor became alongside him.
