According to the conclusion of the fate weaver, if the thief that stole the spring of life is to be found, they just need to look for rank 6 undying godclads nearby or undying legends that just appeared in the area since it is those two kinds of people that are most likely to have stolen the core spring of life.
But even this if conclusion and the way to find the thief turned out to be wrong, the fate weaver also gave the legendary warrior another way to find the thief. She came up with this method by tracking the accomplices of the crime.
The fate weaver couldn't find the person who stole the spring of life, but she could find the people that helped the thief. All she needed to do was go to the scene of the crime to find traces of them.
The strongest trace at the scene of the crime was from the godclad who killed the other guards at the station. The fate weaver was able to use this trace to find the identity of this person and even track their location.
