They circled around together, and several of the sea monster's tentacles gradually wrapped around them, and finally they became entangled like a giant reddish-brown twist flower.

Nangong Yi, who had already formed a seal formation before, froze his tentacles at once, and then pulled out a sword of frost and cut off its tentacles, and a bunch of snake heads fell into the sea, which was instantly swallowed by the whirlpool, turning into bones and sinking to the bottom of the sea.

When everyone thought they could take a breath, the sea monster suddenly roared, and countless red spiritual power fluctuated from its body, and countless snake heads grew out of its tentacles, attacking them again like Nangong Yi.

The spiritual power that Wu Wei learned was the fire system, and on the Black Sea, the fire type spiritual power could not play a role, and it could play a small role.

Nangong Yi held the frost in his hand, used the aura in his sword to cause a wisp of seawater from the black sea, and used the spiritual power of the water system to quickly freeze it and hit it directly on the sea monster, but the sea monster was not affected and could still attack.

The impact of water spiritual power and fire spiritual power on the sea monster is very small, so where is its fatality?

Nangong Yi carefully observed the sea monster while fighting against the sea monster, and found that it had been covering up its heart, and there was a red fire-like demon pill running inside its heart, Nangong Yi smiled slightly, this is it.

Nangong Yi used his spiritual power to enter the frost and began to focus on attacking the sea monster's demon pill.

"The rest of the people dragged its tentacles, and Wu Wen Rong Li attacked its heart with me!"

Rong Li and Wu Wei immediately rushed to support after hearing this, Nangong Yi used swordsmanship to repeatedly scratch his heart, Wu Wei used spiritual power to burn the sea monster's heart, Rong Li took the opportunity to stab into the sea monster's heart.

The sea monster burst out with majestic spiritual power all of a sudden, and suddenly shook Rong Li and Wu Wei, Nangong Yi dodged the spiritual power and slashed into the heart of the sea monster again, and took out the demon pill.

The demon pill broke away from the sea monster's heart, and instantly lost its spiritual power, and the rest of the tentacles and snake heads were also easily killed, and they turned into an octopus and died.

"Lord Wang, it seems that this sea monster should be the origin of the whirlpool."

"Well, this whirlpool disappeared after the sea monster died, and I am more curious that the pirates have been flowing in the Black Sea, why don't the sea monsters attack them or do they cross the Black Sea safely every time?" Nangong Yi analyzed.

"Lord Wang, our ship was destroyed by a sea monster today, should we continue to explore the Black Sea today..."

"Let's go back to the inn today and rest, and we'll talk about exploring the Black Sea tomorrow."

"Yes"

The crowd flew away from the Black Sea, and after they left, the dead octopus slowly floated up to the Black Sea, and an emerald green figure flew in front of him and carefully picked up the octopus.

"The hosts... It's a small fish that is useless," the octopus said as he slowly opened his eyes.

Luo Xianzhi smiled and touched the head of the octopus and said, "Xiaoyu has worked hard today, you have taken this elixir, which can protect the growth speed of your tentacles." Luo Xianzhi took out a small pill from the storage bag and put it on the head of the small fish, and the small pill instantly turned into spiritual power and was absorbed by the small fish.

The little fish absorbed enough spiritual power, and gradually turned into the appearance of a little octopus, and flew into Luo Xianzhi's storage bag.

Luo Xianzhi turned around and left with a smile, and when he left, he arranged a few more prohibitions on the Black Sea, and turned back to the stockade.

When Nangong Yi and the others returned to the inn, it was already evening.
