The battle of Sin Island did not persist for that long. Within less than two days, the great battle had ended!
Lei Banxian, Lei Gu, and company had all perished; not a single Demigod had escaped. A majority of the formidable martial artists of the Sin Island's Thirteen Clans also rested forever near Sky Thunder Island; a minority had managed to escape and was hiding within Sin Island. They intended to use the topography of the island to assassinate anyone that came close, to try and kill as many troops from the alliance army as possible.
A majority of Sin Island's close to fifty million martial artists had died; only a few million had managed to escape. The losses on the East Imperial alliance army's side were heavy as well. As the Sin Island martial artists had been fighting with a death wish, they had risked everything and attacked with everything they had. Many of them had ended up rushing forward and self-imploding together with the enemy.
