Not a Demon

Ever since Lin Feng had mastered the combat body, he had extraordinary control over his body. When he was restructuring his cells previously, he had already sensed something external in his body.

He extended his hand, and a metal sphere gradually condensed in his hand. It was the genetic fusion device.

The genetic fusion device had a certain supportive effect on martial artists who had undergone four life transitions or below, but this did not include Lin Feng, who had cultivated the combat body. After Lin Feng had cultivated the combat body, the current genetic fusion device was actually no longer of any aid to him.

Just as Longbetham had said, this genetic fusion device was only an "auxiliary aid". It was not directly helpful to life transitions, and only provided support.
