183: Rhine Jecker horseshoe crab

However, after exploring the Underground Dark Lake for so long, he hadn't found any trace of the Dunkleosteus or that ancient creature.

The area here was indeed beyond Su Yuan's expectations, incredibly vast, possibly even surpassing Dayang Lake.

And its depth far exceeded Dayang Lake.

Since entering this Underground Dark Lake, Su Yuan had already dived hundreds of meters deeper, and the bottom was still nowhere in sight.

This place was simply too vast, too deep, and too dark; a normal person here might even lose their sense of direction, up, down, left, and right.

Fortunately, with Su Yuan's current eyesight, he could still observe his surroundings.

Su Yuan, accompanied by Gatanothor and Bird-tail Fish, continued to dive, witnessing too many powerful and enormous creatures along the way, far more astonishing than those in Dayang Lake, and soon descended another thousand meters or so.

At this moment, a vast land appeared below, seemingly the bottom.

Su Yuan, dozens of meters above the lakebed, scanned his surroundings, unable to see the end.

“Is this the bottom of this Underground Dark Lake?”

Su Yuan said faintly.

The next moment, the mud on the lakebed erupted, and a massive figure shot out, heading straight for the Bird-tail Fish.

“So there are creatures welcoming our arrival.”

Su Yuan spread his wings and hovered motionless in the water, having already activated his Camouflage Ability, letting the Bird-tail Fish attract powerful creatures.

Since he was already here, he not only wanted to explore the place but also to subdue some dependents.

This seemed to be an arthropod, its body size also reaching about forty meters, which was a common size for strong creatures in this Underground Dark Lake.

Only by reaching this size could a creature be considered a true predator in this Underground Dark Lake.

Even though many Mutated Creatures now possess special abilities, body size is still an important factor in determining their strength.

This arthropod resembled a giant sea scorpion, with an incredibly strong carapace, unusually large eyes, multiple pairs of appendages, and its second pair of appendages were a pair of huge and formidable pincers, with many serrations inside.

“Another aquatic arthropod. I remember these creatures were active before fish dominated the oceans, even older than most fish and dinosaurs.”

Su Yuan muttered to himself, not interfering.

The former Bier Fish, now Bird-tail Fish, was also a creature of this Underground Dark Lake and wouldn't be successfully ambushed.

Facing this sudden attack, the Bird-tail Fish, though surprised, remained calm. Its eyes flashed with madness and bloodlust, and it burst out at a speed of over one hundred kilometers per hour, charging towards the arthropod.

“Boom!”

The two behemoths collided, producing a deafening sound that traveled far through the lake water, startling many creatures into fleeing.

Your dependent, Bird-tail Fish, caused the Giant Feathered Limulid to feel fear, gaining 100 evolution points.

Your dependent, Bird-tail Fish, caused the Trilobite to feel fear, gaining 1 evolution point.

... In this direct collision, the Bird-tail Fish gained the upper hand, biting the giant arthropod and charging towards the lakebed, crashing into a boulder, which shattered into pieces.

The Bird-tail Fish bit through the giant arthropod's carapace, tearing off a large chunk of flesh, while the giant arthropod's pincers also broke through the Bird-tail Fish's scales and fur.

It also opened its mouth and bit the Bird-tail Fish, but as an arthropod, its bite force was an order of magnitude weaker than that of a fish, so its lethality was not great.

At this moment, its two pincers glowed, blurring into two huge pincer-like light projections, erupting with stronger power. The light projection seemed substantial, clamping onto the Bird-tail Fish's body.

The Bird-tail Fish cried out in pain, struggling wildly, its mad eyes filled with killing intent. It opened its mouth and spat out a beam of energy, which blasted the giant arthropod, directly piercing its sturdy shell and breaking one of its appendages.

The giant arthropod went mad, its compound eyes turning completely blood-red, and it clamped down hard on the Bird-tail Fish.

The Bird-tail Fish opened its mouth again, about to unleash an energy beam to pierce the giant arthropod's head.

“This is a forty-meter Mutated Creature; you can't kill it.”

Su Yuan ordered it to stop, and at the same time, he sent Gatanothor to attack, emitting a sound that went straight into the mind, impacting the giant arthropod's mental world, causing it to have a splitting headache and its special abilities to dissipate.

“Oh?”

Just as Su Yuan was about to take this new dependent, a huge figure was rushing from afar, bringing an astonishing sense of oppression that made Gatanothor uneasy, its eight tentacles writhing.

Su Yuan looked over with interest, a hint of surprise in his eyes.

This was a behemoth approaching fifty meters in size, with a streamlined body, like a submarine approaching.

Its pectoral and pelvic fins had degenerated, its tail was diamond-shaped, and its head was enormous. In its slightly open, gaping maw, one could see huge, curved teeth in its lower jaw, resembling both a bird's beak and tree roots.

The proportion of these massive teeth reminded Su Yuan of the Giant Hydrocynus, Giant Dogtooth Characin, and Ornamental Dogtooth Characin, the three major characin predators.

This astonishing tooth proportion, far exceeding well-known fierce fish like sharks, indicated its terrifying nature.

This behemoth was covered in dark green scales, with a uniform color throughout its body, and its eyes were astonishingly large.

“What kind of fish is this? Why does it feel a bit like a lungfish? Could it be a lungfish that evolved?”

Su Yuan examined this behemoth, a smile appearing on his huge face.

The giant arthropod and the Bird-tail Fish had separated by now, both feeling immense pressure and becoming uneasy.

Especially the giant arthropod, it already wanted to flee the area.

Although Gatanothor was uneasy, it still swam forward, not allowing any creature to disrespect the great lord of eternal life.

Su Yuan smiled. The greatest advantage of these dependents was their eternal loyalty. With a thought, he ordered Gatanothor to retreat.

If he didn't intervene against a behemoth of this level, then the two dependents he had just acquired would be sacrificing themselves.

Su Yuan deactivated his Camouflage Ability, and his massive form was revealed in the lake water. Various biological signals could also be captured by his special organs.

In an instant, the Rheno-Jaekelopterus trembled, its body shaking, feeling an unprecedented terrifying pressure.

You caused the Rheno-Jaekelopterus to feel fear, gaining 4000 evolution points.

“Hmm?”

Su Yuan looked at the Rheno-Jaekelopterus in surprise, astonished by both its species name and the amount of evolution points.

Even if its strength was not weak, it shouldn't provide so many evolution points, unless its level of fear was very high.

Given the difference in its body length compared to his, it shouldn't be so afraid.

Most Mutated Creatures still judge strength by body size.

“Could it possess a special sensory ability?”

Su Yuan guessed.

The behemoth from afar quickly approached, sensing Su Yuan's presence, but it did not retreat; instead, it charged straight ahead.

As it neared, its speed suddenly increased several times, its entire body's scales glowed faintly, and it instantly shot forward, its terrifying maw biting towards Su Yuan.

“An ability to enhance speed? No, all attributes have been enhanced. Is it an ability similar to the Fanged Fish?”

Su Yuan remained calm, even evaluating the behemoth's abilities.

He extended two tentacles, and a powerful force erupted, lashing out.

The moment the tentacles touched the behemoth's glowing surface, Su Yuan felt a repulsive force, but it was directly crushed by Su Yuan with brute force!

Two tentacles struck the head of the giant fish.

A muffled thunder seemed to erupt here, and such a massive giant fish was actually pushed back by Su Yuan's strike.

“Roar!”

The giant fish roared in pain, an angry bellow like thunder striking the area. The thunderous sound vibrated and swept towards Su Yuan.

“This skill is similar to that Big Black Fish.”

Su Yuan whispered. Black light overflowed from his body, forming a Black Light Shield that withstood the thunderous ripples.

The next moment, the giant fish attacked again, its terrifying gaping maw, with those root-like giant teeth inside, still shrouded in a faint glow, bit down instantly.

“Crack!”

To Su Yuan's surprise, his Black Light Shield was directly shattered.

Its bite force, or rather the sharpness of its teeth, must be incredibly astonishing!

Just as the giant fish was about to bite down further, Su Yuan's gaze was calm. A fire Dragon suddenly appeared in the lake water, incinerating the water, and blasted the giant fish, sending it flying dozens of meters away.

Even in the lake water, the terrifying high temperature still scorched a layer of its sturdy scales black.

“Roar!”

The giant fish roared furiously, its eyes bloodthirsty and enraged, and it actually opened its mouth to unleash a gray energy beam, which shot over instantly.

“It also has ranged skills.”

Su Yuan nodded, muttering with satisfaction, and then unleashed a true Laser Beam, instantly piercing through the giant fish's gray energy beam.

Afterward, the terrifying Laser Beam continued unabated, piercing through the lake water and striking towards the giant fish's head.

The light-speed attack left the giant fish nowhere to hide, and terror and despair appeared in its eyes.

It was only when the Laser Beam was almost hitting its head that it dissipated in the giant fish's desperate eyes.
