The Hot Realm.

The world war continued raging all across Oceania.

Every day, more and more beasts and variant humans died as more damage was dealt to the primordial origin essence. As more races were defeated into extinction, the more Oceania lost its liveliness.

Compared to the other Great Seas, the Green Mist Sea had it a lot easier but even this Great Sea already suffered a lot from the ongoing world war.

Compared to the fascinating world full of life and adventures that Sebastian transmigrated into, the Green Mist Sea was now a shadow of its former self. 

Now, this Great Sea was filled with death and gloom. 

For 3 days, Sebastian patiently traveled with the group of Megalodons and Great White Sharks that he met as they continued their journey to the Hot Realm where the Great White Empire was located.

Yes, the Great White Empire was located in the Hot Realm.
