These crystals should be the flesh and blood of monsters.

Every muscle and every drop of blood in the monster's body contains a huge amount of life vitality, which can be used for medicine or food.

These crystals come in a variety of shapes, some resembling human kidneys, livers, and other organs, while others resemble insects.

They are neatly arranged and stacked inside the monster, like a treasure trove.

It is by relying on the energy of these flesh crystals that the monster maintains its huge body.

"Gollum!"

The monster let out a groan of pain, struggled, and twisted its body wildly, as if it had been subjected to great torture.

The flesh crystals in its abdomen were entangled by Leon's tentacles, constantly contracting and squeezing, causing the crystal nucleus to gradually collapse and shatter into a puddle of pus and blood.

The monster noticed that something was wrong, and frantically flicked its claws and jaw needles, but could not get rid of Leon's shackles.

It finally gave up its futile struggle, and lay on its stomach in the mud, dying.

Leon walked over and touched the monster's head, finding that it was completely unconscious.

"Why are you running, if you can't win, you'll lie down?"

Li Ang complained: "If you can't do it, just admit defeat!" Or are you afraid you won't be able to beat me? ”

The monster was silent.

Leon sighed, threw away the giant spider's corpse, picked up the dropped key, and turned to leave.

His goal is the cave at the bottom of the lake, looking for more monsters, and killing them to earn contribution points and rewards.

As for the giant spider that he knocked out, he really didn't bother to pay attention to it, anyway, this guy was dead.

After taking two steps, Leon stopped again and looked back at the monster.

The monster remained in its previous position, curled up in the mud, the remaining flesh crystals in its belly melting into a small pothole.

These crystals are the essence of its flesh and blood, and they are the basis of its survival, and once the flesh crystals are damaged, the monster will also die.

"Hmm...... Since this monster is made of flesh and blood, can I eat it, increase its stats, or sell it to a company? ”

Leon thought for half a second, then decided to give it a try, raised his dagger, and prepared to dig open the monster's abdomen and absorb the flesh essence contained in it.

"Squeak."

At this moment, a slight grinding sound sounded next to it.

Leon immediately looked around vigilantly, but found nothing.

Is it your own delusion?

Leon stared at the giant spider suspiciously, hesitating what to do.

"Squeak squeak~"

There was another grinding sound, and the sound grew louder and louder.

Leon narrowed his eyes and looked in the direction from which the sound came, and saw a small shadow drifting down the lake, almost reaching the shore.

It was a little gray-haired monkey.

Li Ang was surprised: "This guy is not dead?" ”

He remembered clearly that when the monster slapped its paws, the little monkey was already frightened and stood there at a loss.

"Was it luck?"

Li Ang secretly cursed and continued to think.

The gray-haired monkey's physical fitness is obviously far beyond that of ordinary humans, and although exhausted after swimming from the depths of the lake, it barely survived and was not shot to death on the spot.

This shows that it has a strong desire to survive.

But it can't swim after all, and even if it manages to land on the shore, I'm afraid it will drown, let alone continue to track itself.

After such a delay, it is estimated that it has been lost......

"Forget it, whatever, a dead horse should be a live horse doctor."

Leon shook his head, picked up the key and inserted it into the monster's head, pried open the wound with all his might, and took out the flesh and blood crystals inside.

The flesh and blood of this monster crystal, the color was bright red as blood, and the shell was hard, faintly glowing with metallic luster, revealing a slight chill.

Leon picked up a crystal and put it in front of his nose and sniffed it, confirming that the material was somewhat similar to the alloy ore on Earth, but it was definitely not an alloy.

"There's a chance to build a set of metal gear."

He thought in his heart, picked out a fist-sized flesh crystal, and stuffed it into his pocket.

This crystal crystal can help the warrior absorb and strengthen the spirit, increase the strength of the soul, and even raise the spiritual threshold.

However, Li Ang didn't need a spirit amplifier now, and this flesh and blood crystal was only the size of a thumb, which could at most meet the daily cultivation of a junior evolutionary, and the effect was limited.

"No matter, take it back to study it first, if you can improve the alloy material, you will make a lot of money."

Leon picked up his backpack and sped along the lakeside towards another route, his speed slightly increasing compared to before.

In a few moments, he reached the edge of the lake.

Ahead is a rushing lake, with a narrow crack in the mountain wall running in front of it.

The crack is wide enough for only one person to pass through, and there is no grass around it, and even mosquitoes and flies refuse to fly here.

"It's ...... Cliff? ”

Li Ang was stunned for a moment, and then smiled, "Haha, I'm really a traverser!" What kind of lake is this Nima, it is clearly a natural 'ladder'! ”

He stepped on the crack in high spirits, and from time to time broken ice slipped and fell into the raging water, splashing layers of ripples.

Leon leapt down and slid down the thick, icy water.

In the water, his auditory vision became extraordinarily acute, and he could hear the faint noise of the lake.

"That's ......"

A strange expression appeared on Leon's face.

At the bottom of the lake, there is another world.

There are many strange fish creatures, some with finned wings, some covered in scales, and whales and sharks hundreds of meters long.

In addition, the most eye-catching thing is a huge jellyfish - this thing is more than fifty or sixty meters in diameter, and it almost stands at the bottom of the lake like an optimus prime, exuding rich life fluctuations.

"Damn, there's a jellyfish!"

Leon's eyes lit up, and he unceremoniously dived into the water, waving his arms to grab the giant jellyfish's tail, and with a sharp tug, dragging the giant jellyfish to the shore.

"Squeak!"

The little monkey crawled out of the crack, screamed in surprise, reached out to grab the giant jellyfish's tail, and jumped away.

Leon ran after its ass and found that the water had faded and turned blue.

"Huh? What's going on? ”

Leon frowned and looked at the lake.

The color of the lake slowly changed from azure to light to lavender, then from lilac to white, then from white to milky white, and finally back to a deep blue that floated away like a dream bubble.

The mysterious scene lasted for a long time before slowly receding and returning to the calm of the lake.

The fishy smell in the lake water gradually disappeared, and all kinds of fish in the lake woke up one after another, scrambling to flee, as if in some kind of panic, not daring to approach the remains of jellyfish.

"Could it be the corpse of a monster?"

Leon muttered, crouched down, and examined the corpse of the giant jellyfish.

Its torso is conical in shape, with cell crystals embedded every three centimeters, resembling a coral reef.

This kind of crystallization is very rare, it is the core part of the monster, and its value is far greater than that of ordinary crystals, and it is a must for the production of precision instruments and scientific and technological equipment.
