In the suffocation of the lizard, Ron sent the dagger directly into its heart, ending the lizard's painful struggle.

The dagger pierced into the heart, accidentally touching a hard touch that did not belong to the flesh.

Ron's heart moved, and after a few slashes made a cut in the belly of the rock lizard, he found a thumb-sized black metal ball from the heart the size of a rock lizard's human head.

The moment Ron grasped the ball with his hand, a tingling sensation came from the palm of his hand.

Ron immediately let go, and the ball rolled to the ground, and after landing on the hard and irregular rocky ground, the ball did not bounce and roll, but slightly submerged its small half into the rock.

When it touches the metal ball, the rock seems to breathe, and bubbles gush out of the ground and become a soft patch.

Ron took out a sealed box from the ring and placed the metal orb in place.

This is an artificial core with highly condensed energy, which just verifies Ron's previous conjecture, this rock and stone lizard has grown to such a huge size, and there is indeed a human factor in it.

However, the energy balance inside the energy core in front of him has been destroyed by the energy vortex due to the long period of time, causing energy leakage, and all the hands will feel numb.

It is the energy that is dissipating and washing away the muscles of the fingers, and this washing beyond the body's tolerance limit will cause serious damage to the body.

Ron estimated that the energy intensity contained in this energy ball was nearly the sum of the energy of four hundred magic crystals, and only such a strong energy intensity would make this rock and stone lizard need to keep making its body bigger and stronger to adapt to its existence.

Gathering such a strong energy in such a small metal ball, the maker of this metal ball will at least be an official wizard, and he will not be a first-level wizard.

As for the lizard, even if Ron didn't kill him, it would soon die from the energy attack in its heart.

Ron searched in the cave**, and the possibility of the lizard entering the cave on its own is very low, and it should have been a test subject that someone got in, which means that there is probably a hidden laboratory hidden here.

Ron carefully searched the nook and cranny of the place, but was surprised to find that the cave was as empty as the eye could see, except for the cold rocks, without any hidden traps or secret passages.

"Did you guess wrong?"

Ron looked at the huge corpse of the rock lizard suspiciously, if this is not the case, then how did this big guy come here, Ron fell into deep thought, when his eyes subconsciously swept over the rocks soaked in the blood of the rock lizard, Ron's eyes lit up, and finally found a clue.

Blood flowed freely on the ground, and even more so in the scratches made by the lizards, but in some places the blood was cut off because the scratches were broken.

When Marais removed the massive body of the rock lizard, Ron saw a large witch circle on the ground.

Ron has no attainments in the witch circle, but he has the True Eye, and through the search and comparison of the True Eye, Ron finally found the origin of this witch circle.

Ron was slightly surprised when he saw the name of the witch circle, because the name of the witch circle was Savage Howl, and it was a very secluded defensive witch circle, so cold that it didn't even spread outside.

Ron was able to find it because Casper, the researcher of Echo of Truth, had secretly entered the Eye of Truth with some of his bootlegged goods when he was recording the Echo of Truth's inheritance materials, including the Savage Howl.

Karpas had been following his legendary wizard mentor on the Witch Circle, but because of certain commonalities between the Echo of Truth and the Witch Circle, he joined the laboratory to study the Echo of Truth, even if his interest was only in the Witch Circle.

When Karpas studied the Echo of Truth as a witch circle, he got some unexpected results, and this Savage Howl was one of them.

Unfortunately, before he could publish these results, the Titan Disaster struck, and during the development of the Eye of Truth, he had to hastily record these things together with the materials of the Echo of Truth.

Since there is a Savage Howl here, perhaps this is a secret laboratory of Karpas.

This witch array, which may have existed for tens of thousands of years, has not been worn out in the years, but this Karpass's methods are surprising.

Ron scrutinized the entire Savage Howl and guessed about the methods of the Karpasian wizard.

He first blocked the entrance to the secret laboratory with a piece of hard obsidian blessed with extraordinary solidity, and then covered the ground with rock formations, submerging everything underground.

Over the years, the tide has risen and fallen countless times, and the rushing sea has wiped out the rock layer covering above, revealing the inside of the package.

The sea overflowed the Hidden Howl etched into the obsidian, triggering a Witch Circle module reserved by Karpass, and a blood-mutated rock lizard was released.

Karpas may have wanted the lizard to guard the entrance to this laboratory, but more likely, the lizard reminded the wizards who happened to enter here that there was a dusty laboratory here, and not to let it be forgotten forever.

At the moment when the rock and earth lizard was released, the breath of something in the laboratory overflowed at the same time, and a small octopus kraken who stayed here was keenly aware of the unusual breath, which was a trace of the breath that made it addicted, so it began to stay here day after day, year after year, confronting the rock and earth stone lizard, trying to find the source of that breath.

Ron was taken out of his mind by the sound of the waves crashing against the rocks, and when he turned around, Ron saw the octopus siren emerge from beneath the water's surface, waving its tentacles and striking the water.

It was furious and eager to rush up, but the uncooled corpse of the rock lizard told it that going up meant danger, and that the enemy in front of it was more difficult than the lizard.

Ron smiled slightly, and pressed the energy-overflowing metal ball at a node of Savage Howl.

After a flash of light, the ground began to shake, and the massive obsidian began to slowly descend until a huge black hole several meters square appeared in front of Ron's eyes.

A rancid smell escaped from the black hole, like a piece of carrion that was swaying its stench unscrupulously.

Ron took a step back, only to inhale a little of the stench, as if a pile of mud had been stuffed into his body, clogged between his mouth and nose, making him almost unable to breathe.

The suffocating stench spread, but Ron's eyes grew brighter and brighter, for he knew what made the octopus siren so obsessed with guarding the cave.

The kraken in the distance also smelled the stench, and its scarlet-eyed eyes rushed to shore desperately, its tentacles swinging like whips and crushing Ron.
