Most cultivators rely on demonic energy to sense nearby monsters, such as resentful spirits in a stealth state, which are invisible to the naked eye. But in the spiritual sense of the practitioner, they are as cold as an open freezer.

But the monsters in the Changjin Precision Factory are very peculiar, whether it is a gold swallowing rat or a black long worm, Song Xing can't sense the demonic energy emanating from their bodies.

Even "qi" does not exist, which can be mistaken for a dead thing.

Because of this, he didn't even notice when another long black worm quietly came out of the exhaust pipe and coiled beside Song Xing. I don't know why their huge bodies don't make any sound when they shuttle through the pipes.

Song Xing couldn't sense the black long worm, but this bug could detect the slightest tremor. At that time, Song Xing's hand was on the exhaust pipe, and he suddenly woke up the monster hiding in it.

It crawled out silently, raised its upper body to face Song Xing, and a very small friction sound came from its body.

Song Xing's hair suddenly stood on end, no matter what, being put on the face by such a pitch-black giant insect was terrifying enough.

He endured the discomfort in his heart, sacrificed the true element of the body, and slowly retreated. Maybe this kind of bug doesn't move fast, and Song Xing doesn't want to fight an unknown enemy.

At this time, carefully staring at the black giant insect in front of him, Song Xing found some clues. Generally, insect demons retain a lot of insect features, such as chitinous shells and disgusting flagellar links.

But this is not the case with this giant worm, and its appearance is somewhat ...... It's so beautiful. Not only does it not have those disgusting body structures, but it is smooth as a mirror, presenting a very perfect line.

Song Xing noticed that its shiny metallic shell was probably not just "like metal", it was simply composed of metal.

Is this a mechanical giant worm?

It's Reiki Resurrection, not the Terminator, the end of the world, bastard!

Like the sound of running water, a crack opened in the center of the giant worm's body, like a transport cart opening the cargo hatch. Because he had seen this giant insect carrying slag before, Song Xing knew that he wanted to load himself.

At this time, if you don't run away, Song Xing floated on tiptoe and then retreated.

However, the giant insect rabbit fell and directly knocked him down.

Song Xing thought that the insect was slow, but this guy was so fast that he flew up. He only had time to hold up the True Yuan Shield, and as soon as his eyes were black, he was swallowed by the giant worm.

Invisible and invisible, there was only a slight friction sound in his ears with a strange rhythm, and Song Xing was really flustered at this time. Whoever swallows a bug is not a pleasant experience.

However, the expected fatal crush did not hit, and he only felt that he was following the bugs. Song Xing took a few seconds to suppress the fear in his heart, and waved his hand to light up the light technique on his fingertips.

There are no imaginary internal organs and mucus in the belly of the giant worm, and it is flat and square, but it really looks like a warehouse. It's just that the surroundings are closed, Song Xing can't find the exit, he knocked on the inner wall, and there is an echo of metal all around.

This black giant worm is really made of pure steel.

At this time, Song Xing was not in a hurry, he sat down cross-legged and analyzed the strange situation in front of him. As he could see, these metal giant worms were indeed a means of transport. If nothing else, this giant worm is probably transporting the metal ingots spit out by the rats outside.

And the rats just now are probably also made of metal.

That's interesting.

First of all, it is not uncommon for monsters to be completely composed of metal spiritual materials, and Song Xing has heard that some strange heavenly and earthly treasures can give birth to spiritual wisdom by themselves. But that's a very small hand, and it has to be a very powerful spiritual material.

It's unheard of for a monster made of a lot of steel like this.

In addition, depending on the situation, they seem to be working together. This is even stranger. When you think of ore, slag, ingots, and transportation, it's not an exaggeration to say that this is a metal smelter.

So, what do these strange monsters smelt metal for?

Could it be that there is a deeply hidden organization in Changjin Precision that is building an army of robots?

No, it doesn't make sense. Song Xing quickly rejected the idea, which was too sci-fi.

Regardless of whether or not the current technology of mankind can create such mechanical creatures, it is impossible to explain it by talking about energy alone. If this giant worm is a scientific creature, then it must need electricity.

However, Song Xing couldn't find any trace of its use of electrical energy, and it couldn't even see a single line inside it, but there was some kind of faint aura flowing.

If it can move, it must be some kind of metaphysical creation.

Song Xing immediately thought of the trick, but quickly shook his head.

Not like.

He had the privilege of seeing a puppet made by a New World Elder. The puppet was immensely powerful and had incredible defense, but it was really shabby, not as sophisticated as a clock.

The biggest difference is that the puppet needs to be controlled by the creator with divine thoughts, and can only control one head at a time. There are at least a few hundred metal rat demons in this factory, and Song Xing doesn't think that there are hundreds of mechanics who spend a lot of effort to create this kind of puppet that can only gnaw ore.

Neither a scientific creation nor a metaphysical creation, Song Xing had a hunch that this might be a special monster in the middle of science and metaphysics.

He drew his sword and slashed at the inner wall of the metal, he now needed to escape from the belly of the giant worm. God knows where the steel giant worm will take him.

Xuanjin's spirit sword was infused with true yuan, and unsurprisingly, a huge hole was cut in the inner wall of the steel. The sword pierced through the giant insect's body, and the light from the outside faintly penetrated.

Although the giant insect is made of steel, it can actually eat pain. It rolled on the ground, and Song Xing in his stomach was also unstable with his center of gravity, and he was shaken to the ground, as if he had experienced a violent car accident.

Fortunately, he has a True Yuan Shield, and such a car accident scene can't hurt him. It's just that the sky is spinning, and I can't aim to tear open the wound of the sword just now.

Song Xing simply ignored it and swung his sword and slashed. This giant iron worm has suffered, its body is just ordinary steel, how can it withstand the spiritual sword of a cultivator.

After a while, the original smooth appearance became full of holes.

It struggled for a moment to stop moving, and seemed to be dead. Song Xing inside followed with two more swords to tear open a big hole, and finally got out of the belly of the giant worm.

With two breaths, Song Xing kicked the corpse of the giant worm. Although it looks powerful, it is just made by mortal iron, and he was easily killed.

Looking at the wound of the giant worm, there was no mechanical structure or sparkling electrical wiring inside, only a viscous-looking metallic liquid flowing out.

Is this its blood, incredible.

However, Song Xing quickly gave up his plan to find out, something was approaching rapidly, and it seemed that it was a new enemy.

He raised his sword and watched as the giant worm seemed to have led him into a factory somewhere. Sunlight poured in through the windows above, and there was a pile of wreckage on the ground, both metal and the flesh and blood of the usual youkai.

Out of the corner of Song Xing's eye, he even saw the stump of a human being.

The rancid smell of the air mixed with the smell of some kind of motor oil made his brow furrow.

Click, click, click, and rhythmic mechanical footsteps, the powerful enemy finally showed itself around the corner.
