My bloodline is so eager to improve.

At this moment, the hearts of both rock-skinned lizards had been collected.

Otto wiped the sweat from his forehead and let out a long sigh of relief.

Although the process was somewhat thrilling, I managed to complete most of the task.

Otto felt that this commission wasn't too troublesome. Although the Rock-skinned Lizard was registered as a medium-sized commission in the Adventurers' Guild, they still managed to resolve it.

However, just as the two thought the battle was over and were preparing to continue their exploration, the earth suddenly began to tremble violently.

A deafening roar came from the distant rock face, a roar filled with anger and violence, as if it came from hell.

A terrifying aura swept over them, causing Otto and Tessa to change their expressions drastically.

At this moment, Tessa's face turned extremely ugly.

She gripped the hammer tightly and said in a deep voice:

"Damn it, our luck is terrible."

Before Otto could ask Tessa what was going on, a giant lizard, three times the size of an adult rock-skinned lizard, crawled out from behind the rock wall.

The giant lizard's skin was a deep black color, covered with dark red lines that flowed slowly beneath its skin like blood vessels.

Its eyes gleamed with a bloodthirsty light as it stared intently at Otto and Tessa.

It also has a sharp horn on its head, and thick black mist is wrapped around the horn in the eyes of the Lamp Spirit.

The fog was thicker and more malevolent than the one on the rock-skinned lizard.

"This is no ordinary rock-skinned lizard."

Otto's voice carried a hint of solemnity.

"Is it the leader, or a mutated aberration?"

Monsters also have the potential to evolve and mutate.

Otto had encountered similar kobold variants before, but he never expected that he would encounter such a rare event just by hunting a few rock-skinned lizards.

I don't know whether to call them lucky or unlucky.

Just as Otto was pondering this, the mutated rock-skinned lizard discovered the corpses of two other rock-skinned lizards on the ground.

It let out an even more furious roar. Seeing that both of its men were dead, it immediately concluded that the two adventurers before it were responsible. It pounced on all fours and charged at them.

Although it is huge, it is incredibly fast.

In the blink of an eye, it arrived in front of the two of them.

It raised its huge claws and slammed them down on Otto and Tessa.

The claws made a whooshing sound, as if they were about to tear the air apart.

Without hesitation, Otto immediately cast his spell, Windwing Messenger.

A gentle force enveloped Otto and Tessa's bodies, and their weight immediately decreased.

Otto grabbed Tessa's arm and leaped backward.

The two of them instantly floated back more than ten meters, dodging the fatal blow.

With a deafening roar, the rock-skinned lizard's massive claw slammed into the ground.

The ground instantly cracked open, sending debris flying and dust billowing into the air.

Several small trees nearby were uprooted by the shock, their branches and leaves scattered all over the ground.

"It looks like a mutant species. Even the evolved rock-skinned lizards couldn't possibly have this kind of speed and strength."

Tessa just felt that things were a bit troublesome.

But Otto took a deep breath, and the magic within his body unleashed a deafening roar.

Angry!

This roar contains powerful spiritual energy, which not only attracts the attention of the mutants but also has a chance to cause some mental shock.

Sure enough, the deformed rock-skinned lizard paused for a moment after hearing the roar.

"Now!"

Tessa seized the opportunity and swung her hammer.

"Obey the laws of our Lord, evil things shall not harm living beings!"

A translucent cube shot out from the hammer again, locking the mutant firmly in place.

The aberration angrily slammed into the solid, its surface flashing with light, fine cracks appearing on its surface, on the verge of shattering completely.

"Its power is too great; I'm afraid my sealing technique won't last long!"

Tessa frowned, a hint of anxiety in her voice.

Fine beads of sweat appeared on her forehead, clearly indicating that maintaining this sealing technique was extremely taxing on her.

Upon hearing this, Otto simply nodded.

He knew that he had to act quickly, because once the sealing technique was broken, they would be in an even more dangerous situation.

"Can you try to control the sealing technique as much as possible, at least make it open its mouth, like you did just now?"

Otto shouted at Tessa.

Having said that, Otto drew his iron sword, preparing to use the Azure Moon Thrust.

The Golden Sun Honey Core Ring on his fingertip was also ready, the golden crystal on the ring shimmering with dazzling light.

"no problem!"

Tessa immediately understood.

She gritted her teeth, increased the output of her magic, reduced the volume of the sealing spell's cube, and directly locked the mutant's throat.

With a suffocating sensation in its throat, the mutant opened its mouth wide in pain, revealing sharp teeth and a foul-smelling tongue.

"Now!"

Otto shouted.

The eerie blue light emanating from the iron sword became dazzlingly bright as Otto unleashed a full-force attack, Azure Moon Thrust.

He transformed into a streak of blue light and charged toward the mutant.

The sword energy pierced into the mouth of the rock-skinned lizard with a soft sound. Immediately afterward, Otto activated the Golden Sun Honey Core Ring.

A golden cone of light, accompanied by moonlight, pierced the mouth of the rock-skinned lizard.

An immense force erupted within its body, blasting a deep gash in its skin, from which black blood gushed out, splattering all over Otto.

But the mutant didn't fall; instead, it became even more ferocious.

Clearly, such an attack would be lethal to an ordinary rock-skinned lizard, but Otto's attack only severely injured the mutant in front of him, without killing it.

Seeing that his attack had failed, Otto immediately withdrew and retreated.

It was at this moment that the Rock-skinned Lizard finally broke free from Tessa's sealing spell.

It suddenly raised its head, and a black ray shot out from the sharp horn on its head, heading towards Otto.

[The black cat that ferry souls is telling you to jump to the right.]

Fortunately, Otto was quick-witted and agile enough, and with the help of the Soul-Crossing Black Cat, he reacted immediately.

He simply stepped back a few paces to his right rear, thus dodging the attack once again.

But when the black beam struck the ground, it made a strange sound, and the ground was instantly corroded into a bottomless pit, from which billowing black smoke rose.

But it was at this moment that Otto noticed something was wrong.

His spiritual eyes clearly saw that a wisp of blue mist was swirling around the gap in the single horn.

At the base of the unicorn, there was a black crystal. Although the crystal exuded a strong aura of curses, it was also surrounded by a clear blue mist.

This is such a good face!

"so it is."

Otto's eyes lit up.

"This is the key to defeating it!"

That black crystal was clearly the source of power for this mutant; destroying that crystal would completely defeat it.

Thinking of this, Otto took another deep breath and activated the Azure Moon Combat Technique.

This time, he ignited the Soul-Purifying Flame in his hand.

The warm flames danced at his fingertips, gentle and sacred.

Otto exerted force with his feet, and his whole body shot out like an arrow released from a bow.

He leaped forward, transforming into a streak of light, and stabbed towards the mutant's horn.

The mutant seemed to sense the danger and desperately twisted its body, trying to evade Otto's attack.

But at that very moment, Tessa's sealing spell descended once more, binding its limbs tightly and greatly restricting its movement.

With a crisp sound, Otto's longsword pierced precisely into the black crystal at the root of the mutant's horn.

The Soul-Purifying Flame instantly enveloped the crystal, completely burning away the cursed power within.

The black crystal made a crisp cracking sound, then broke into fragments and scattered on the ground.

The rock-skinned lizard let out an extremely mournful scream. The scarlet stripes on its body gradually faded, and the bloodthirsty light in its eyes slowly dissipated.

Its body swayed, then it crashed to the ground, kicking up a cloud of dust.

After a while, it finally stopped struggling, and its body gradually cooled down, clearly indicating that it was dead.

But Otto didn't stop there.

He swung his longsword, slicing open the mutant's chest and taking out its enormous, still slightly beating heart.

At this moment, Otto finally breathed a sigh of relief.

He stumbled and almost fell.

The battle had almost exhausted all his magic and stamina.

Fortunately, the harvest was quite good.

Your understanding of the Windwing Messenger has reached a new level.

[Windwing Messenger upgraded to LV3.]

Just as Otto was sensing the changes in the Windwing Messenger, Tessa quickly came over, supported him, and asked with concern.

Are you alright?

There was a hint of worry in her voice.

Upon hearing this, Otto shoved Tessa away.

He wiped the sweat from his brow, his face pale, and said coldly:

"It's just that it consumes a lot of energy."

Tessa wasn't angry when he pushed her away.

She simply picked up the black crystal fragments from the ground while muttering to Otto:

"This was really dangerous."

If it weren't for your guiding light and your purifying spirit, we might already be dead here.

I really need to give Eileen a good scolding when we get back; she actually assigned us such a dangerous mission.

Upon hearing this, Otto said with a half-smile:

"It's also thanks to your sealing technique and the Shield of Law that I had the chance to attack its weakness."

"By the way, didn't you say before that you couldn't use your abilities consecutively within a short period of time?"

Otto narrowed his eyes and looked at the girl picking up crystal fragments in front of him.
