Wang Xu lowered his head to look at the teacup Fang Mu was handing to him once again.
Looking at the twisting silver silkworm in the teacup, Wang Xu was initially puzzled by Fang Mu's intentions.
But after carefully examining the condition of this little silkworm, Wang Xu's spirits were lifted.
A touched expression appeared on his face!
This silver silkworm could actually allow a Beast Master to advance in rank!
Once a Beast Master advanced in rank, they could then command a Guardian Beast that was a whole major level above their current status.
This treasure was extremely useful for Beast Masters below the rank of Six-Polar Star.
However, since he was already a Six-Polar Star Beast Master, contracting this Infinite Silver Silkworm would be a waste.
Wang Xu took this as a reward given to him by Fang Mu.
Wang Xu did not believe that Fang Mu would waste such a precious resource.
