Lin Yu quickly stabilized his mind, clenched his fists, looked around coldly, his ears pricked up, carefully identifying the movements around him, and identifying the location of the black shadow.

However, there was silence all around, without the slightest sound, and the silence was terrifying, and it could be seen that the black shadow was also trying to avoid making any noise.

Lin Yu stretched out his foot and swept it on the ground, swept up a few pieces of gravel from the ground, grabbed it, and then threw it out violently, hitting the dark shadows around him.

The stone struck out with a sound of breaking through the air, but it didn't hit anything, and after hitting the wall, it instantly bounced to the ground with a few crisp bangs.

It can be seen that this black shadow is not on the first floor.

Lin Yu hurriedly dodged to the stairs, quickly rushed to the second floor, glanced around, and found that there were more shadows, the light was even darker, and he couldn't detect the figure of the black shadow at all.

As before, he swept away a few small pebbles from the ground again, glanced around with sharp eyes, and said coldly, "Come out, with your speed, in such a short time just now, you can only rush to the second floor at the earliest!"

At this time, he suddenly reacted, after the black shadow rushed into the building just now, he also rushed in quickly, there was a lot of time in between, after he rushed in, there was no black shadow, and there was no footsteps.

It also means that the moment he rushed in, the black shadow had already been hidden and immovable, otherwise it would not have been possible without the slightest sound.

In such a short time difference, the black shadow can only rush to the second floor at most, and rush to the third floor to the death!

Therefore, Lin Yu only needed to find the third floor in turn in this way, and he would most likely be able to find out this black shadow!

Now the advantage for Lin Yu is that although the black shadow is hiding in the dark, in order to avoid revealing his position, this black shadow does not dare to make the slightest sound, which means that the black shadow does not dare to move its position, and can only stop in one place.

After Lin Yu finished saying this, there was still no sound on the entire second floor, he did not hesitate at all, raised his hand, and quickly threw out the gravel in his hand, and the gravel accurately hit several shadows on the second floor.

But as before, the stone only ended up hitting the wall.

Lin Yu frowned, then quickly rushed to the third floor, and said coldly at the same time, "Now, you can't run away!"

Just as he had reached the third floor, there was a sudden noise in the upper hallway.

Because the entire office building is rough, the sound is heard very clearly.

Lin Yu's heart trembled, and he looked up in surprise, and he could tell where the sound came from, at least above the fifth floor.

In such a short period of time, this black shadow was able to rush above the fifth floor?!

Although Lin Yu couldn't believe it in his heart, he still reflexively rushed up the stairs, and rushed to the fifth floor in an instant.

At this time, a dark shadow on the fifth floor was quickly rushing to the outer edge of the balcony, and then jumped down without the slightest hesitation.

"Want to run?!"

Lin Yu's eyes were cold, and he quickly followed, rushed to the balcony and jumped over, chasing the falling black shadow.

After the black shadow hit the ground, it quickly rolled forward twice, relieving the gravity of the fall, and then flew towards it like an arrow.

At this time, Lin Yu had also followed him to the ground, but unlike his tumbling and unloading force, Lin Yu unloaded the gravity on his body with his footsteps and posture the moment he landed, and at the same time, his right hand shook violently, and a small pebble that he had been holding in his hand quickly flew towards the ankle of the black shadow.

Burst!

After the stone hit the crook of the black shadow's leg, the black shadow instantly staggered and planted itself on the ground, but the black shadow reacted in time, and at the moment when he was about to grab the ground, he slammed the ground, rolled forward with the momentum, and rushed forward desperately.

Lin Yu kicked under his feet, quickly chased after the black shadow, and soon rushed behind the black shadow.

After the black shadow noticed Lin Yu behind him, his body suddenly turned violently, and at the same time, he shook his hands and threw out several darts in an instant.

Lin Yu's expression changed greatly, and he quickly made a mistake, and his body flexibly dodged some of the darts, and at the same time held his chest up to block the remaining darts.

One of the darts swept down his face, cutting a tiny bloody gash in his face.

At this time, he had already rushed to the black shadow, and smashed the black shadow in the chest with a swift punch.

Click!

I only heard a crisp sound of chest breaking, and the black shadow's chest was concave, and then the whole person flew upside down like an offline kite, falling heavily to the ground, and his body trembled a few times, and he lost his breath.

Wrong!

Lin Yu's face suddenly changed greatly, and he secretly screamed in his heart, just now his more powerful punch smashed into the chest of this black shadow, and the black shadow was not in a big problem, now how could this punch directly shatter the black shadow's sternum?!

And he felt that the punch he had just punched was not like a blow to the armor at all, but a blow to the flesh.

He frowned, and then rushed to the black shadow with an arrow, and dragged the black shadow up, and then his face changed greatly.

This man is not the number one killer in the world at all!
