That really couldn't be called a scar anymore—it's just on the surface of the skin, a faint, threadlike mark as thin as a strand of silk.
If this is supposed to be a scar… then a suturing technique like this is something no doctor in this world could possibly master!
The silk thread ran very long, almost trailing all the way down to Wu's lower abdomen.
You could imagine, if this was where Wu had been "opened up" back then, then a cut this long would have exposed most of his mid-abdomen and lower abdomen!
This level of disembowelment…
And done in a crude mountain cave, with no medical equipment at all—it simply couldn't be accomplished.
Even if nothing else, the blood loss alone would have been enough to bleed a man to death.
