Before Yun Ran came, she had heard it from Feng Chen.
This Gu poison was refined by the Gu Lady who poisoned him in order to obtain him.
The goal was to control his body so that he would not be able to leave her under the control of the parasitic poison.
Therefore, the Gu poison in Mo Beiyuan's body did not affect him much in the past few years, other than not being able to touch other women.
However, it was impossible for Mo Beiyuan to take the initiative to touch any woman.
Before he met Yun Ran, he was like a monk with a clear heart and few desires.
The effect of the parasitic poison on him was only triggered when the two of them came into contact after reuniting.
However, this problem could be avoided. As long as the two of them did not get close, it would be fine.
Both of them were fine as long as they stayed far away.
