"Zizizizi......" This is the sound of Kuroki's flesh and blood.

It's like there's a stove inside it that's baking endlessly, and the hot air waves swing slightly.

The next moment, Kuroki began to tremble violently. It swelled and grew rapidly, getting taller and stronger! From about 0.6 meters to more than 4 meters high, it almost reached the ceiling.

But the next moment, its body began to contract. Muscles bulge like steel bars, as if steel had been poured. The black one is the strong fascia on the surface of the muscle. The red is the boiling blood of Kuroki!

It went from nearly five meters tall to three meters high.

Shunan suddenly found that the black wood seemed to be in a different direction from the white wood. Its ossified vesicles and eyes have barely changed, and the evolution points are all added to the muscles!

A pair of wings has a distinct sense of heaviness, as if draped in a layer of armor. The two iron claws were like steel pillars, firmly rooted in the ground. Its back muscles swelled to the sides, exposing the middle vertebrae, and a jagged bone spur gradually grew.

Kuroki's head and pointed beak are deformed. It became something like a mask and armor, and when its mouth closed, it looked like a giant cone. The specific shape is a bit like the mask Birdbill Doctor that Shunan once saw.

Whoosh...... Whoosh...... Whoosh......

The mask has two large breathing holes, and air enters and exits, making a sound like a truck starting.

Shunan glanced at Kuroki's muscles and nodded with satisfaction, as he consumed all the evolution points.

The introduction of the second rune has changed.

The basic ability of the eagle eagle Kuroki has not changed, but there are two more marks similar to the passive underneath.

[Giant Force: The blue-eyed vulture is rapidly developing towards the aspect of the physique, and the flesh is strong to the extent of exaggeration. It has far more power than other birds of prey, and it is extremely tyrannical.]

[Strong wall: The vulture has a very thick muscle layer, has a very high ability to resist blows, and is an excellent meat shield. Even if a car hits it, it won't be a big deal.]

【Ability. Hammer peck: The vulture's skull has undergone a drastic mutation, making the entire bone layer denser and thicker, and the beak of the bird becoming conical. The powerful muscles and spine of the vulture can flung the beak out like a hammer, blasting the opponent like a nail.

"This is a violent type of meat shield?"

Shunan still remembers that Kuroki has one more madness ability than Hakuki, and he will become fleshier and stronger after casting!

In addition, he found that Kuroki didn't seem to have evolved to the limit of the structure, and that he could put in some more evolution points.

Shunan glanced at Shiraki's introduction again.

"Dead-Eyed Vulture: One Ring Limit"

"Cannot continue to evolve, success rate: 0"

"No further fusion, success rate: 0"

"Extraordinary Abilities: Explosion, Dead Eye"

His right hand was raised, and the panting Kuroki instantly turned into a rune and returned to Shunan's secret ring.

There was a flurry of turns, leaning to the side.

Half an hour later, in the cave. Shunan looked up at the light shining from the hole at the top and thought.

"Do you want to leave now, or do you want to continue exploring?"

Leave now to avoid risk. After all, Shunan has already gained enough benefits, and he has a lot of money.

If you keep going, you'll be in danger, but you'll have a chance to earn more Evolution Points, as well as Ancient Legacy.

Xiu Nan glanced down at the two runes on his left and right hands, clenched his fists, and walked quickly into the darkness.

When there is no strength, giving up is a sane strategic retreat, the wisdom of one. To give up when you have strength is to be cowardly and lack courage!

Xiunan's subordinates have continuously evolved to get two generals!

Don't you even dare to continue to break through like this?

If he retreats, he himself dislikes himself.

***************

Thundered! Thunderous sounds echoed through the dark passages, and it was difficult to stop one after another.

In the darkness, two huge figures were fighting.

The three-meter-tall white bone statue trampled wildly on the ground, stepping on one footprint after another, and slamming forward like a raging tank. Punch out like a cannonball!

And Kuroki, who was suffering from its blow head-on, didn't even take a step, but his huge body trembled.

"Roar!" Kuroki roared violently, his muscles swollen inch by inch, and a pair of eyes turned red.

Install the latest version. 】

Boom! A black iron claw slammed into the head of the bone statue, slamming it against the wall like a meteor hammer.

"Bang! Boom! Boom! Boom! Bang ......"

The sound of crashing echoed through the passage.

Kuroki used his great strength like a frenzy, pressing the white bone statue against the rock wall one after another.

The black surface rock layer peels off, revealing the hard, smooth white bones underneath. The statue was constantly struck, and the whole body was lit up like a relief loop.

Its right hand suddenly turned into a spear, and with a fierce reflexive stab, it shot at Kuroki's chest.

It was extremely fast, and an afterimage streaked through the air.

Kuroki roared, and the jagged bone spurs on the midline of his spine burst out, revealing a red glow. The whole spine was like a big bow, bending backwards and flicking.

Its entire head slammed into it, and a ripple of air exploded where the cone-shaped beak passed.

Bite! A spear into the chest!

Click! The bird's beak is banging on the celestial spirit cover!

"Sudden Sudden Sudden Sudden ......" is advancing inch by inch.

Like a piledriver, it crushed the entire head of the bone statue, and the neck shattered rapidly.

The circuits throughout the statue's body quickly dimmed, and the spear that had been thrusting forward was no longer supported.

Ding, unable to hang on the ground.

Shunan stepped out from behind Kuroki, glanced at the wound on its chest, and beckoned to take it back.

"You have earned Evolution Points: 6"

With one foot on the leg of the white bone statue, he strode over, and Shunan stood in front of a white door.

The door panel is carved with various black carvings, and in the center is a ring.

There is a chain-like pattern around the ring, which spreads out radioactively, inch by inch, and spreads all over the entire door panel.

Xiu Nan hesitantly reached out and touched it gently.

With a bang, the black door opened automatically.

He hesitated for a moment, then stepped inside.

As soon as the footsteps fell, the whole space instantly brightened, and the black wall lamps lit up on the walls.

The beating light of the fire illuminated everything around them.

Shunan took a quick glance and saw that it seemed to be a small library, or a private study?

On the left, a large space is occupied by neatly arranged black bookshelves, each with a classification brass plaque.

On the right are some simple experimental instruments, as well as a few resting tools. A purple desk caught Shunan's attention, and books were placed on it.

writing utensils, and a diary spread out......
