I'm really coufused where undernet 6 is . I'm at the part where you have to find the S.Sensor.You need to find it so he can defeat shademan when he is in the coffin. The guy said it was near the somewhere in undernet 2. But when I went there a black/purple navi told me somebody stole it. The navi said it was near undernet 6. If you could tell me where undernet 6 is it will be very helpful.Thank you a lot in advance.

Try and make less sense when you post something, we understood too much and its really helpfull
