After thinking about it, Fang Yi took out the sponge that could absorb gray blood from before.

Place it on one of the gray metal beads.

Sou!

The two had just come into contact, and the sponge suddenly seemed to absorb enough energy, and the four sides immediately stood up, turning into a small square cube, no longer in the previous sponge state, but still becoming extremely hard.

Fang Yi tried to keep the two in touch, turning into a cube-shaped sponge, but there was no response.

It's like you've eaten too much, you've eaten too much, and you can't eat anymore.

This shows that the amount of gray energy that the sponge can store is so much, and this gray metal bead can make the sponge reach the storage limit of gray energy in just a moment.

Fang Yiyou thought that these two gray metal beads would not be simple, but he didn't expect that the effect would be so good.

It was a bonus.

"Good stuff!"

Put the two gray beads away.

Fang Yi only then took the Cangci Sword, and used the gravitational pull of the Cangci Sword to collect all the gray beads that had been scattered nearby before.

By the way, the Cangtian Sword that was inserted more than 100 meters underground was also recovered.

After cleaning up the battlefield briefly, Fang Yi counted them, and there were more than a hundred gray beads.

Since the size of each gray bead is different, it is judged by the square.

The size and weight of the ash beads should be linked to the total amount of ash energy in the ash beads.

Put everything away, not to mention, it's a little heavy.

No!

Wait a minute!

Fang Yi suddenly found that it wasn't that these gray beads were too heavy.

It's my physical fitness, which has dropped dramatically.

When he returned to normal, the skin on the back of his hands was wrinkled, and even old age spots appeared, like dead bark on a withered old tree.

After checking the rest of the body, there were more or less age spots.

The muscles of the whole body are atrophied, and there is no sense of strength that should be in the prime of life.

This is still the situation with the blessing of his own skills, and if he returns to the color world, I am afraid that the situation will be even more serious.

"It's a little bit bad."

The consumption of the Lonely Sword Code is still too serious.

In addition, the character is a middle-aged office worker, who is not good at exercising and has poor physical fitness.

When the vitality is consumed, it is easy to age.

touched his face, and it was clearly an old man's face.

There is no need to change the appearance, next time there is any need for disguise, directly open the Lonely Life Sword Codex, consume vitality, and go to age quickly.

After thinking about the derivative effect of the Lonely Life Sword Codex, Fang Yi put away his thoughts.

Putting away his things and taking Xiaowen with him, Fang Yi was preparing to go to the Gray Sect's base.

Suddenly.

He heard a voice.

A rhythmic, chorus-like sound, in unison.

Woo! Woo! Woo!

Subconsciously look up.

I saw the night sky in the distance, the black clouds that had already fled, were black and oppressive, flying back, towards him.

The multi-legged gray beasts with turtle shells in the black cloud group were swallowing the black clouds, staring greedily at Fang Yi as if they had found prey.

No!

It's not Fang Yi, the direction they're staring at is ......

Where the corpse of the Night Sky Behemoth is located!

After the death of the night sky beast, the metal ball in the core was indeed broken down into a large number of gray beads.

But those metal rings remained in place, targeted by these gray beasts.

Woooooooo

The gray beasts in the black clouds swooped down and frantically pounced on the metal rings, completely ignoring anything else.

You may not even notice that Fang Yi is still beside you.

Boom! Boom! Boom!

One after another, the gray beasts fell like missiles and swooped directly on the metal ring.

The crocodile's long mouth opened and tore directly at the metal ring.

Click! Click!

The metal rings are so hard that they break their teeth.

But these gray beasts soon grew new fangs from their mouths, and I don't know if it was an illusion, but the new teeth grew brighter in color, and began to gradually turn to the metallic color unique to the night sky beasts.

Looking at these gray beasts like parasites, greedily lying on the corpses of the night sky giant beasts and sucking the remains, Fang Yi thought for a moment and vaguely understood something.

However, he is not a biologist, and he is not prepared to study the biological ecological chain in the gray field.

After a slight comprehension, he took Xiaowen and stepped back.

I just experienced a big battle, although it is not a problem to deal with these gray beasts for the time being.

But the number of gray beasts is so large, if you fight for a long time, the physical consumption is really a bit too much to keep up.

Anyway, these gray beasts only thought about devouring the night sky giant beasts, and they completely ignored themselves, just giving themselves room to get out of it.

Those gray beasts, gobbling up, looked like beggars who hadn't eaten for dozens of days, and suddenly served a table full of Han people in front of them, and the appearance of eating was ugly.

Even many gray beasts tore each other because of the competition for the position of the metal ring, like the food habits of wild dogs.

Fang Yi observed carefully, and found that the gray beast that first gnawed the metal ring, the turtle shell seemed to have become larger, and the color was more inclined to the metallic color unique to the night sky giant beast.

This further verifies Fang Yi's previous conjecture.

The Night Sky Behemoth is the evolution of the Gray Beast.

It is not clear whether it is in the growth period or in the full body.

I have to say that the gray beasts in the gray sect haven't even studied the juvenile stage yet, and they can deduce the existence hypothesis of the complete body stage, which is really powerful.

I don't know if it's blind, but it's probably based on some clues, or the remnants of the night sky monsters.

Gradually distanced himself from the gray beasts, just when Fang Yi loosened his mouth a little-

Woooooooo

The movements of the gray beasts suddenly froze in unison.

As before, all of them took off in unison, returning to the black clouds in a panic.

"Is it ......?"

Fang Yi's face changed slightly, staring at the situation behind him, and suddenly his pupils contracted suddenly.

Ahead, there was nothing, there was calm.

But Fang Yi knew that another night sky beast had appeared!

Boom!!

Only the familiar sound of explosions was heard.

The violent wave of qi suddenly exploded from a distance.

Under the churning waves.

The black clouds scattered in all directions at a speed visible to the flesh.

Before those gray beasts could react, a huge metal mouth appeared out of thin air without warning!

The huge metal mouth is full of dense small mouths and teeth.

The mouth is like a nesting doll, and the visual effect alone makes people feel uncomfortable.

And wait for this huge mouth to close.

Bang!!

That space, as if it had disappeared out of thin air, took on a strange sense of distortion.

When the distortion gradually disappeared, the black clouds had disappeared, and only the panicked gray beasts fled in all directions.

There were a few of them, and they even ran in the direction of Fang Yi.

After a slight pause, Fang Yi not only did not dodge, but directly spread his white wings and greeted him.

The sword light flickered a few times.

These fleeing gray beasts were immediately slashed by Fang Yi under his sword and fell to the ground.
