The dim light shone through the turbid dusty glass on the floor, and countless dense dusts that were flying gently were forced to show their insignificant existence.

It's been a long time since I cleaned it.

Holding his breath, Langren strolls in the corridor like a silent ghost.

My eyes were looking at the third door tightly, and a drop of blood that was accidentally left on the surface was solidified at the bottom of the bag.

"Um?"

Langren suddenly stopped and looked back at the corner of the ceiling.

‘Too sensitive?’

Langren stared for three seconds, and nothing happened.

When I was about to move forward, the third door suddenly opened.

"Hiss...How long will it take for such a boring guard to go..."

The man with a black scar on his face scratched his hair, walked out of the room, took out a box of cigarettes from his pocket, and walked step by step towards the corridor in the empty corridor.

When he turned around the corner, there was a dull sound of cutting, followed by the sound of warm liquid wrapped in soft blocks hitting the floor.

"Gu...hehe—"

An indescribable vibration of air spurted out from the hollow of the throat, bulging many pink blood bubbles.

Lang Rin quietly crossed the pool of blood, walked up a few meters and opened the door and walked into the room where the man came out, stood at the door and looked.

"Guardian? What to guard?"

The room was a very normal room, and there was nothing strange except that the bed was moved to the living room.

Lang Ren then set off and flipped around, but found no strange items within the scope of custody.

"I think...it shouldn't be in the category, right?"

Langren frowned and drew a map to see: "If you were to guard things, then there would probably be a place before you go--"

Lang Ren's self-talk came to an abrupt end.

I saw a three-dimensional geometry composed of coordinate lines on the map, glowing slightly.

Langren turned the map and found that the thing had become independent and changed directions without being rotated by the map, so he closed the map directly.

This large pattern floats in the air, which looks like a line composition of a twelve-minute big question cut from a math college entrance examination paper, and may be even more complicated.

Langren tentatively touched a trace of mental power.

“Buzz…buzz…”

The moment I touched it, a crossing in the line composition lit up, and it was very conspicuous towards the North Star among the stars.

"This...is this location where I am now?" After comparing the map, Lang Ren reacted.

Suddenly, a sense of induction appeared, and Langren lifted up the bed placed in the living room with one hand.

It’s not that something is placed under the bed, but that there is a rune engraved on the base of the bed. At this time, the rune is echoing the light spot.

Lang Ren's doubts were instantly resolved!

"Formation...is this a Formation?"

With wide eyes and looking at the mathematical three-dimensional geometric diagram in front of him, Lang Ren couldn't speak for a moment.

Influenced by the film and television dramas in the previous world, in his inherent impression, the formation has always been a plane geometric figure, but what is placed in front of him now is actually three-dimensional!?

"This...every cultist guards a formation node, which is a talisman, forming a huge formation that includes the entire city?"

But what is the function of this formation?

Yuhuaxian and Jiumo jointly killed the threatening B-level abilities that the prosecutors had no effect on them, leaving only the C-level storm that had no effect on them, pretending to fight back and forth. At the same time, Yuhuaxian retreated a large number of units, leaving some people to guard and build a formation.

‘It should be said...Du Demon and Yuhuaxian are still within the scope of cooperation?’

‘The Dove Demon delayed, why did he delay? Until now, we even dispatched the rescue team... But they still didn’t make any big moves, and they thought we were too few people?’

Langren seemed to have thought of: they wanted to ambush the support troops of the Order Army Camp.

"Then what is the function of this formation?"

Lang Ren glanced at the runes on the bed board. His understanding of formation was illiterate. He didn't guess it, so he copied the runes' appearance in the sea of ​​consciousness. Then he covered the bed with his backhand and sorted out the bed.

"Okay... I only killed people, I didn't find the formation... It's time to leave."

Lang Ren doesn't want to be targeted yet. If he rashly destroys the stability of the formation, he is not sure whether he will be discovered by Yuhuaxian.

Just as everything was taken care of, he turned around and held the door handle with one hand, Lang Ren's body instantly felt as if it was struck by lightning and remained stiff.

"when...?"

Lang Ren clearly remembered that when he came in, the door was not closed.

If it were to say that the door was closed by itself, the sound on the door bolt would not be noticed with his acuity.

"Stallurgical psychic? At least level B, is it from the Dove Demon?"

If the other party is not on the surface, you must not start a war in this other party’s field.

Lang Ren retreated like lightning and rushed straight towards the living room window.

Just as he was about to arrive at the window, he suddenly fell into complete darkness.

The entire room is wrapped in a huge shadow from the structure of the space!

Langren stretched out his hand and couldn't see his five fingers at this time!

So he instinctively showed his superpowers, and the long sword that burned fire was in his hand, following the memory, and slashed out one by one.

boom!!!

It was like a dangerous building was exploded, half of the building was shattered, and the darkness wrapped around the room was torn apart by the sharp flame blade, and Lang Ren instantly escaped from it.

"shadow?"

Lang Ren quickly fell to the ground and looked at the black shadows in surprise.

It fell down from the tenth floor lightly. After falling to the ground, the spirit cat blew up a handful of dust and slammed the ground with one foot, as if an arrow from a string was shot into the distance of the road.

Lang Ren has recalled what he noticed before. Now if you think about it, it probably triggered an alarm. However, the other party's trigger trap was too hidden, and his similar recognition was unable to observe it. He only instinctively sensed the abnormality, so he thought it was his own sensitive.

The huge black shadow that originally wrapped around the room seemed to have substance, and moved like a liquid water flow, escaping into the shadows everywhere in the sun.

"Danger!"

The drums are trembling!

Langren quickly inserted into the ground with a knife, lifted up a piece of gravel, and stopped his sprint in time with the force. The sewer manhole cover that was close to him was lifted away, and countless spikes condensed by the dark shadows bloomed into a huge ink flower.

Lang Ren's nose tip was a little itchy at this time, because a sharp thorn was only one millimeter away from the tip of his nose.

In this brief confrontation, in Langren's ninja eyes, countless attack trajectories have closed his retreat.

It turned out that the moment the spike exploded, a circle around Langren had been surrounded by black shadows.

Each of the sharp thorns in front of me turned into a sharp and soft tentacle, and one of them turned into a afterimage.

clang—

Lang Ren took the sword and resisted the huge sting of the black shadow thorn while watching around.

He did not find the other party's body.

At this time, several giant thorns appeared in the black shadows surrounding Lang Ren, and they were beaten down in a storm with the huge move in front of Lang Ren.

Dozens of large tentacles of buckets were beaten at the same time, and Lang Ren only had a long knife, and no matter how fast he waved it, he could not take them all.

But just so happens that this is also within the scope of breaking through.

"Gap, handover, overlap, weak!"

Lang Ren suddenly saw through all the weak positions of the surrounding black shadows, bent down, put the long sword around his waist, and pressed it gently on the back of the knife as if he was hesitant.

Take out the knife and dance!

In an instant, the sword light burst out, and a perfect circle divided the connection between all the tentacles around Langren and the lower half.

Tornado Slash!

Silent-

The sound of burning came to Lang Ren's ears. All the tentacles floating in the air that lost the source of the black shadow were corroded under the sunlight. In a blink of an eye, there was no wisp of blue smoke left.

"source..."

Lang Ren was thinking, and his body was not slow. After breaking the circumference, he jumped to the wall of the high building more than ten meters away on the side, and then gently tiptoed and flew to the top of the stairs.

The shadow seemed a little unwilling to give up. After retracting back to the sewer, he came downstairs of Langren from some gap and swam up along the shadow of the wall.

"This person is really a C-level?"
Chapter completed!
