There wasn't much to contemplate—going head-on would surely result in defeat, the only option was a stealth attack, killing a portion of the Fishmen first to gradually weaken the Big Tribe.
Once the Fishman Big Tribe was weakened to a certain extent, and his own Clan had leveled up, with the enemy weakened and his side strengthened to a certain degree, then with a final push, he could annihilate the Fishman tribe.
On the second day, Lin Xiao split all the Clan members into two groups: one to stay home and fish, the other led by him on a mission.
A total of three hundred Naga and twelve hundred Fishmen, after finishing their prayers at the central altar of the Temporary Tribe, left under his leadership into the vast ocean.
