Chapter 3594

Alder followed the professor to his laboratory and finally found a moment of peace.

The professor deliberately drained all the water in the laboratory so that Alder could feel more

comfortable too.

Alder smiled and silently accepted the professor’s kindness. Josua started to study the picture on the

iron plate left by the professor.

The content of the picture was very clear. Alder could tell at a glance where the underground ruins

were, the extension of the ruins, and the mileposts. It was also clearly written on the iron plate the

creatures guarding each milepost.

This showed that the merfolk kingdom had once tried to invade this place but the result was not ideal.

No matter what, Alder wanted to take a look for himself.

When Alder was about to go out, he found the princess outside the laboratory door.

“I was afraid you were busy, so I didn’t want to disturb you. Here are some things from our merfolk

kingdom for you to have a taste.”

The princess respectfully handed over a tray.

Seeing this tray, Alder realized that the princess did not seem to have the demeanor of a princess. She

seemed more used to being a servant.

Alder waved his hand at her with a smile and said, “Thank you, but let’s wait until after I return from the

ancient ruins.”

After saying this, Alder left the professor’s laboratory and walked in the direction of the ancient ruins.

Although he could swim in the water, Alder preferred this way. Josua did not notice the princess’s

hesitance as she looked at his departing back.

Right after Alder left, the professor walked out with a sullen face.

“I’m warning you, if you don’t keep your mouth shut, the entire merfolk kingdom won’t have any living

creatures left…” The professor’s tone was very serious.

Hearing that, the princess immediately became nervous.

“I didn’t say anything. Don’t do anything to my people.”

The professor snorted coldly and closed the door.

Alder followed the professor’s map and soon arrived at the marked location of the underwater mine.

Josua used his power of insight to explore the area but found that the so-called exotic beasts guarding

this place were not that powerful.

Based on Zagu’s ability, he should be able to defeat them easily. Alder frowned before heading in

another direction.

It was an underwater cave. After using his power of insight, he only found a few water snakes.

However, maybe because they had survived for too long, they developed intelligence.

Combined with living near the mine, their strength was comparable to the peak of eight stars.

Alder had just reached the entrance of the cave when the water vibration caught their attention.

“How many times have we told you that we don’t need the hearts of merpeople now?”

Hearing this voice, a trace of doubt flashed across Alder’s face.

According to the princess, the merpeople’s hearts were taken away by humans. However, it seemed

that these water snakes had gotten the hearts of merpeople before.
