The Strongest Beast Tamer With the Strongest System-Chapter 31: Boundless Vitality

(Boss, Boss, I’m getting crushed! My body could be crushed if this continues!) Ellie’s panicked voice echoed just moments after Leonardo left.

He hadn’t expected it to escalate this quickly.

But the tree still hadn’t revealed itself, so Leonardo didn’t respond.

If Ellie were truly on the verge of death, he would feel it and could immediately grant her permission to escape.

"Mm."

He then noticed the cage beginning to sink into the ground.

Through his connection with space, Leonardo sensed a living presence waiting below—

But it wasn’t the tree.

(Ellie, burn everything beneath you!) Leonardo commanded.

Even without teleporting, Ellie could escape the cage by burning it down.

Buzz!

Black flames erupted from inside the cage, incinerating its base and tearing it open, revealing Ellie spewing Abyssal Blackflame from her beak.

The flames didn’t stop. They began scorching the earth itself, because Ellie could also sense the creature hiding underground.

Normally, fire couldn’t bore through soil.

But by continuously burning the surface into ash, a hole gradually formed.

Buzz!

A jet of green mud shot upward from underground, colliding with the black flames.

But the mud was easily burned away.

"This doesn’t seem like a tree," Leonardo muttered.

The presence felt more humanoid—just shorter.

After a brief thought, he sent a buff to Ellie, empowering her flames.

"Aghhh—!" A hoarse scream finally echoed.

The creature could no longer escape. Even the mud it expelled failed to withstand the black flames.

Leonardo caught a vague glimpse of its form.

Everything else had nearly burned to ash—

But the creature itself was only scorched, not destroyed.

(Ellie, stop for a moment!) Leonardo ordered.

With both of them watching, the creature wouldn’t be able to retreat underground again.

Ellie withdrew her remaining flames. She also wanted to see it clearly.

It was green.

Truly humanoid—but its skin looked layered with roots.

Most of its body had been burned, yet it began regenerating at astonishing speed.

In less than five seconds, it was fully restored.

Its eyes showed fear as it looked at Ellie, trying to dive back underground—

But Leonardo appeared behind it, knife in hand.

He slashed across its abdomen, confident it wouldn’t die from that.

Even though Leonardo wasn’t physically strong, the S-Class weapon sliced through its body effortlessly.

Yet there was no blood.

Inside, he saw interconnected roots instead of organs.

More shocking—

Moments later, the wound sealed completely.

Leonardo couldn’t imagine the level of vitality required for such regeneration.

It could even use root magic.

As far as Leonardo knew, root-type magic didn’t necessarily require Mana—it could substitute vitality instead.

Some high-level Healers who acquired similar skills could do that.

This monster could be considered a healer among monsters.

But there had to be something sustaining that absurd regeneration.

Shua! Shua! Shua!

Leonardo slashed again and again.

It was too fragile—easy to wound.

Three massive gashes appeared—

And just like before, they healed within seconds.

Of course, the creature didn’t remain passive.

Ten identical figures appeared at once, sending long roots toward Leonardo in retaliation.

Ellie didn’t allow it.

She unleashed black flames again, incinerating them—

But it was meaningless.

Ten more trees appeared.

As long as the green creature’s vitality wasn’t exhausted, this wouldn’t end.

So how was it supposed to be killed?

If it couldn’t die, how would the gate open?

’There must be something supplying it with vitality!’

Leonardo was certain of it.

No Level 10 being should possess such endless regeneration.

He glanced at the massive umbrella-like tree again.

It had to be connected somehow.

(Ellie, let’s destroy its Monster Core directly!)

Leonardo finally changed strategies.

As long as the Monster Core was destroyed, any monster would die—

But Ellie had to do it to gain EXP.

(Boss, how?) Ellie asked.

Unfortunately, she couldn’t tear open its body like Leonardo did with his knife.

And burning it didn’t work—the creature regenerated faster than she could incinerate its flesh.

(Send your flames straight into its mouth!) Leonardo replied.

(Ohh, why didn’t I think of that?) Ellie sounded startled by the idea, then instantly appeared in front of the green creature.

She thrust her small beak straight into its mouth.

Buzz!

Black flames immediately flooded the creature’s mouth. Some flames spilled outward, but most of them poured down its throat.

It couldn’t even scream anymore. Its eyes widened in agony, the only sign of its suffering.

Its body began to swell slightly, yet it still seemed capable of enduring.

The flesh inside its body was burning—but it regenerated at the same speed.

(Boss, I’ve found the Monster Core...) Ellie transmitted.

(Can you destroy it?)

(Yes, but it will take a few minutes. It’s very hard. Please help me hold it still so it doesn’t keep moving.)

Leonardo moved at once upon hearing that, grabbing the creature with both hands to restrain it.

Its physical strength was even weaker than his. It could barely struggle.

BANG!

A sudden explosion thundered through the area, followed by a surge of energy that pushed Leonardo and Ellie backward.

The Monster Core had exploded.

DING!

(Ellie has killed a Level 10 A-Class Monster and gained 100 EXP!)

An unsatisfying notification appeared, but Leonardo didn’t care about that right now. He was more curious about the secret behind this creature.

It collapsed as a corpse—

Yet unbelievably, even as a corpse, its wounds continued to regenerate until not a single injury remained.
