Even now, the three mermaids still can't believe what they're seeing.

A human actually killed a shark-man with his bare hands.

Yes, he didn't use any weapons, just his hands and fingernails, and he killed the shark man directly.

Such strength is probably comparable to the most terrifying being in the deep sea.

At this moment, the mermaids couldn't help but wonder, if Shi Wuxie were to encounter that being, who would be the ultimate winner?

"Pfft..."

Before they could recover from their daze, Shi Wuxie had already reached out and pierced through the shark's skull, then started rummaging inside.

This scene undoubtedly refreshed the mermaid's worldview once again, making her feel a chill run down her spine and a headache, and she couldn't help but drift away.

This benefactor's strength is abnormally powerful, and his methods are extremely ruthless.

"Pfft..."

Shi Wuxie moved quickly, and in just a moment, he took out a light blue bead from the shark man's head.

The bead was about the size of a lychee, blue in color, and surrounded by a faint black mist.

Shi Wuxie was able to immediately tell that those things were demonic energy.

"Splash..."

After Shi Wuxie took out the bead, the shark man's enormous corpse instantly turned into a pool of black water, which then flowed from the deck into the sea.

"What is this?"

Holding the bead in his hand, Shi Wuxie examined it while asking the three mermaids a question.

"This is the energy center that all marine organisms generate themselves through cultivation."

Looking at the bead, the three mermaids couldn't help but swallow hard, their eyes filled with longing, clearly showing their great interest in the bead.

"It's called the Sea Spirit Pearl. Sea Spirit Pearls are also graded, from white to yellow to green to blue. The highest grade pearl is purple. This blue pearl indicates that the shark's strength is already at the level of a human god. Although it's only light blue, it's still very precious."

"Oh, is that so?"

Shi Wuxie examined the Sea Spirit Pearl for a while, then looked at the mermaid and asked, "So, what use is this pearl to you?"

Upon hearing this, the three mermaids were all energized and looked at Shi Wuxie with gratitude in their eyes.

Could it be that their benefactor intends to give this treasure to them?

My benefactor is truly a wonderful person!

"It's useful, of course it's useful."

So the three mermaids nodded repeatedly and answered eagerly, "The Sea Spirit Pearl is the essence condensed from the elements of the sea, rich in very concentrated marine energy, which has a great effect on enhancing the strength of us marine creatures."

"So that means if you eat this Sea Spirit Pearl, you can quickly increase your strength, right?"

Shi Wuxie nodded knowingly and continued to ask, "Then I wonder how strong its effect on increasing strength is?"

"This involves the classification of marine life."

The mermaid's eyes followed the Sea Spirit Pearl as it moved, barely managing to control her excitement as she said, "From the lowest to the highest level, they are divided into White Sea level, Yellow Sea level, Green Sea level, Blue Sea level, and Purple Sea level. Among them, Green Sea level is equivalent to the Saint level of humans, Blue Sea level is equivalent to ordinary gods, and Purple Sea level is equivalent to ancient gods."

"I never imagined that this thing would be so beneficial."

Upon hearing this, Shi Wuxie understood, and under the mermaid's expectant gaze, he nodded and put away the Sea Spirit Pearl.

Mermaid: "..."
