Seventeen days later.＊,

Calculated the time, Green had already traveled around the edge of the world 322 times in this fragment of the world without specific coordinates.

This fragment of the world is indeed constantly changing its self-form, like a soft irregular jelly shape.

After so many searches through the bottle mouth world, on this day, after Green, who was flying boredly, passed through the chaotic energy ribbons, suddenly, a shadow of a foreign object in the oblique corner stunned Green.

This is……

Metal Castle Laboratory, finally found!

It is more than 300 meters high, and the main castle is connected to dozens of houses, emitting a cold metallic luster. There is an energy harvesting device at the top of each house. Although most of it has been damaged, there are still a few that are operating automatically, and flashing from time to time.

Since this bottle mouth world has no sky, ground, and direction to follow, this castle is a lying and floating foreign object in Green's vision.

After adjusting himself to the same inclination angle as the castle, Green flew cautiously towards the metal castle.

According to the information of the wizard's metal villain, this metal castle is a bottle-mouth teapot that comes with the world's own. It is the aircraft of the ancient mechanical wizard. Later, it was transformed into a laboratory by her mentor's mentor.

And her mentor "lives" in this metal castle after the experiment failed.

Um?

On the castle metal gate, the deep marks of the six nails were very eye-catching, and they looked like a finger deep. It should be caused by the deformed monster transformed by the metal tutor in the castle.

Without the protection of the wizard cover, Green was extremely cautious in oppressing such an attack.

Thinking of this, with a "crunch", Green pushed open a gap with a slightly solemn look on the metal door as high as seven or eight meters, and walked in.

The door automatically creaked and closed again.

The fragments of the magic crystal lamp are scattered on the metal floor, and there are some other debris. I don’t know what the mechanical device principle is in this metal castle, but gravity actually simulates the environment of the wizard world.

Suddenly, Green seemed to have discovered something, and he picked up a scale from the broken debris.

This scale is blue-gray, with no pattern, like a shell, and is very hard in material. It should be the scales of some kind of ancient invertebrate protozoa.

"Is it evolving yourself?"

After muttering to himself and guessing, Green shook his head in denial and said, "No, it should be a repulsive reflection. Just like blood witchcraft, without the long-term self-will guidance of the wizard, these foreign objects will soon have some repulsive reflection, or change, or excretion with the wizard itself."

There is no dust in the metal castle, because there is no large amount of biological cells metabolism and no natural dust here, so it is still brand new.

After passing a metal corridor, Green came to the castle hall.

The four walls of the castle hall, dozens of meters high, are full of claw marks everywhere. The once luxurious and beautiful large crystal chandeliers on the ceiling have now fallen to the ground. They are damaged and old.

This time, Green discovered a large piece of metal dissolution trace.

Walking next to the metal layer with dissolution traces, Green reached out to caress and felt it.

After a while, Green got some information. This should be the instinctive witchcraft left in the cell memory in the image of the metal little man's crystal ball.

From the perspective of state, it should be some kind of erosive liquid witchcraft, and ice-attribute witchcraft should be able to perform some restraint.

He raised his head. Green looked at the environment in the hall and began to think.

Needless to say, the greatest wealth of any wizard's private residence is the wizard's knowledge in the laboratory. With so many rooms in this metal castle, it obviously takes Green's plunder for a while.

Before this, since you have to clean up the unwise monster, it is better to prepare for it.

Thinking of this, Green cut the gap between the dimensions, took out a large number of high-purity fire crystal stones and magic stones, and began to arrange them according to a regular set of magic circles to trap.

After a full hourglass time, he simply tested the magic circle. Under the truth, Green nodded with satisfaction, and his figure flashed and disappeared from the hall.

Looking for one room after another, there was a disgusting and strong smell everywhere.

Most rooms are idle, and occasionally some rooms that once stored experimental materials are mostly destroyed, and the experimental specimens are eaten.

Gradually, as Greene penetrated deeper and deeper into the metal castle, a door that was still protected by magical bans made Greene slightly stunned.

call!

The immortal flames ignited, and Green landed on the magic restriction with one hand. As the magic restriction flickered and darkened for a while, it finally went out with a "pop". Green pushed open the metal door of the room with a "squeak".

"Uh, is this?"

The room was empty, with only a black round metal ball in the center that was very abrupt, and I didn't know what it was.

Green's eyes flashed under the face of Truth, and he walked over in confusion.

The metal ball has a diameter of about three meters, the metal material is very special, and the feel is a bit soft. It seems to be a strange witchcraft, and it requires elemental passwords to control it.

"Hmm? It turned out to be an unexpected gain. I don't know what it was." Without hesitation, Green directly put the metal ball into the dimension gap.

Regarding cracking elemental passwords, there are specialties in art. Some demon hunting wizards in the Holy Tower have guys who specialize in studying such wizard knowledge.

With a slight joy, Green left the room and continued to search for other rooms.

This is a laboratory for collecting insect specimens. It is now in a mess, and all insect specimens disappear.

This is a laboratory for collecting plant specimens, and it is also in a mess. An orange vine bud that can take root in metal is covered by the ruins. Green was very surprised and carefully collected it.

In the library, there were pages of chewed and torn to pieces everywhere. Green collected some barely recognizable books and scrolls.

...

After half an hourglass, finally, Green stopped at the entrance of an open hall.

"Finally found it!"

In combat posture, Green immediately untie the first layer of wild instinct, and as a layer of dense scales surged out of his body, his eyes looked at the monster that seemed something was wrong.

Overall, this is a crawling creature, sticking to the wall like a gecko, tearing a sheepskin scroll, as if eating as a piece of leather.

The pair of hind limbs are extremely thick, and there seems to be some suction cup-like body structure under the feet, and some remaining scales have not fallen off.

The claws of the forelimbs were six sharp nails worth tens of centimeters, as if six sharp knives were sharp, shining and emitting a faint light.

The scales on the body had completely fallen off, revealing the bright red muscle tissue under the scales. A head that was almost as ferocious as a beast exposed its fangs. The nose sniffed back and forth.

Um?

No, it also has a big mouth on its abdomen, which is also the source of the aura of human despair. This is some kind of mutation produced by the transplant and grafting of the black wizard cell?

"Roar! Meat..."

With a "swoosh", the monster howled and rushed over the moment he discovered Green.

A pair of claws that looked like six sharp knives and daggers easily melted the metal wall. A pair of suction cups under the feet of the rear limbs made it crawl on the wall like walking on flat ground.

"drink!"

With a loud shout, Green responded extremely quickly and pressed the monster's hideous head. He jumped up under his feet to avoid the attack of a pair of sharp claws on the other party.

With a "squeak", twelve claw marks were caught on the metal floor.

After his eyes and pupils under the face of truth, with a "bang", the monster's head was pressed to the ground by Green. At the same time, Green quickly collected the monster's life information and jumped backwards flexibly.

Boom! Boom! Boom! Boom!

The three firebirds exploded with witchcraft, and the rolling flames instantly submerged the monsters. Green flew towards the magic circle with a piece of meat in his hand.

"It's so weak. It's not at the same level as the image of the metal little man's crystal ball. Is it hungry?" Green smiled excitedly while guessing.

Fortunately, the opponent's strength dropped sharply after his reincarnation. He didn't come in to investigate again.

Of course, even if this monster is only of its current strength, it is definitely not something that the metal villain secret wizard who has been reincarnated for decades in the Life Box can handle.

While preparing for cursed witchcraft, Green was quietly waiting for the monsters to break into the magic circle.

"Roar..."

A fierce and cruel phantom rushed out, without any hesitation, and plunged into the magic circle. For some reason, Green suddenly found that the magic circle became difficult to control when the monster broke in.

What's going on?

In an instant, after Green thought a lot, he suddenly had a flash of inspiration. Could it be that this monster was the master of the magic array during his lifetime?

This also explains the powerful magic forbidden source of the metallic witch's experimental castle.

With Green's crude magic restriction knowledge, he could only fiddle in front of some creatures in the foreign world or magic apprentices.

Green couldn't help but feel a little angry and ashamed. He had used a lot of time to set up the magical prohibition, but was broken by a wizard walking corpse who had lost his mind, which was really a bit disgraceful.

"But it doesn't matter...the Frost Giant Sword!"

After taking a deep breath, Green performed the same inferior curse witchcraft, and stretched out his hand and a giant frost sword appeared.

Suddenly, the surrounding temperature seemed to drop, and large pieces of ice crystals floated.

This is the witchcraft that Green completed in three months after obtaining Millie's Ice Marrow Body talent and after catching up on ice element knowledge through the past few years of travel, he came to the Metal Little Man Castle to recuperate.

Overall, it also refers to the talent of the giant Li Yan to refine the lava giant sword.

drink!

After slashing the Frost Sword into the air, Green took a look at the giant sword that had dissolved most of the giant sword. After the magic power surged, there was a "crunch, crunch" sound, and the giant sword condensed again.

Without hesitation, Green rushed back towards the weak-starved monster holding the Frost Sword...

After one eighth of the hourglass time.

The giant frost sword in Green's hand turned into ice crystals all over the sky. He kicked it with his feet and cut it into several pieces of ** minced meat. He shook his head, and was about to continue to explore other valuable things in the metal laboratory, but suddenly realized something was wrong.

Gudong, Gudong...

There was still a faint heartbeat in the corpse on the abdomen of the monster that did not stop.

"The Heart of Life!"
Chapter completed!
