"Fixed star Gu, this is like a rope tied around my neck. Although I have methods to get rid of it, I need a lot of time to prepare. If I want to immediately get rid of the fixed star Gu, unless Bai Ning Bing took it back personally, otherwise, I can also chop off my left forearm…" Fang Yuan's heart was burning with this urge.
Fixed star Gu was hiding in Fang Yuan's forearm, once he discarded his forearm, Tie clan's four old-timers would only be able to retrieve his broken limb.
If if he did that, Fang Yuan would lose a limb.
He would have to treat it in the future, making a broken limb grow back, creating something from nothing, it would spend a lot of effort.
Not mentioning how troublesome healing would be, the thing now was once he loses his left arm, it would be alerting his enemies. Tie clan and Bai Ning Bing would immediately realize that Fang Yuan knew what was going on, and would immediately start their attacks.
