In a bathroom at the corner of the stairs on the fifty-second floor, Leng Aotian, who had transformed into a green dragon form, put his hand on one wall to instill the power of sealing, a strange symbol appeared on the wall and disappeared immediately, and then Leng Aotian went to another wall and repeated the action just now, and after a while, there were invisible symbols on all the walls.

Leng Aotian was about to leave, the door of the bathroom was pushed open, and a soldier walked in cautiously, facing the dark room, he didn't touch the light switch on the wall, and the light on the room would produce an instant visual blind spot, which was a fatal danger for an environment that could be close to each other at any time, and of course a seasoned soldier would not make such a low-level mistake.

The warrior swept the modest space with the illuminated pillar of light from his rifle, and after a thorough inspection, he was sure that there was no one hiding here. The warrior walked out again to inspect the next room. Leng Aotian jumped out of the window of the room where the warrior's next target was located, moved sideways back into the bathroom on the outer wall, sat down, and quietly looked at the dark corridor.

Unhurried footsteps sounded in the corridor again, and the man who was walking was completely different from the warriors in front of him who were cautious and slowed down as much as possible, and did not hide his whereabouts in the slightest. It's not a trap, it's based on a strong confidence in your own strength. When the strength reaches a certain level, it becomes a trap placed in the open.

An old man of medium stature walked past the door of the bathroom, his body was straight, his white hair was meticulously combed, and he looked like he was going to a dinner party, rather than hunting and fighting.

The old man walked through the open doors one after another, without any gesture of expectation, to check if there was anyone in the room. As he expected, there was almost imperceptible footsteps coming from behind him, and there was a disturbance in the surrounding air currents, indicating that someone was sneaking from behind.

The rat is out of the hole. The old man sneered in his heart, and a small and delicate pen pistol slid down his sleeve and landed in his palm. The pistol can eject a five-centimeter-long military spur at the front end, and can also shoot two rounds at the back end, and the bullet is coated with a special biological neurotoxin, which can often exert amazing power in hand-to-hand combat.

The wind pressure behind him became stronger, just as the old man had expected. This means that the person behind him began to speed up, but his footsteps could hardly be heard, and if it weren't for the old man's strengthened hearing, I am afraid that he would not be able to perceive that someone was approaching behind him purely by hearing. The old man was even a little admired in his heart, this intruder had the qualities of a natural killer and hunter, and it was really a waste to kill him now.

The muscles in the old man's arm squirmed, pushing the pen pistol towards the palm of his hand, and when there was still a few centimeters left, the tip of the pen pistol began to pop out of the edged edge.

However, the old man's ears suddenly heard a slight crackling sound, and years of experience immediately made him know that it was a slight crackling sound in the air! This can only mean one thing, and that is that the attacker behind him is completely faster than he expected!

The wind pressure suddenly became stronger, blowing the old man's silver hair flying! The old man was just about to turn sideways when a light suddenly swept over from the corner of his eye, so strong that he couldn't look at it directly. He was immediately alerted to the effect of a silent flashbang, and if he looked behind him now, his eyes might even be blinded by the bright light without any protection!

Even without vision, the old man could perceive the approximate position and movements of the attacker, his body was like a felled tree, he suddenly fell to the left, his right hand was raised flat, he held the pen blade back, and stabbed hard in the back! The old man's series of movements were lightning fast, and the whole person gave people a strange feeling as if they were completely weightless, as if they would fly out at the slightest touch.

And so it is. The position where the tip of the pen blade points is Leng Aotian's mid-abdomen, as long as Leng Aotian blocks a little, he can experience the agility of the old man's level forty assassin.

However, Leng Aotian had no intention of slowing down or blocking at all, and hit the old man's body at an astonishing high speed, and his left knee hit the old man's waist fiercely, knocking the old man's body into the air like a dead leaf. Leng Aotian ignored the blade that was already stuck in his abdomen, and continued to rush forward with all his strength, pushing the old man to the opposite wall, and then fit and crashed into it!

The huge recoil force bounced back both the old man and Leng Aotian, and the solid walls withstood such an impact that they were suddenly covered with cracks.

Leng Aotian landed on the ground, and took two more steps back before he stood firmly, and there were already two bottomless blood holes in his abdomen. In the impact just now, the old man pulled out his pen blade, and then used Leng Aotian's momentum to stab Leng Aotian's abdomen again where there was no armor to protect it. In such a short moment, the old man's assassination skills can really be described as exquisite. It's just that he was hit by Leng Aotian with all his strength, and the old man's body also sounded the sound of crackling and dense bones, and the injuries he suffered would only be more serious than Leng Aotian.

Leng Aotian exerted his strength again under his feet, and rushed towards the old man again, ignoring the pen blade that the old man stabbed at his chest and ribs, he swung with both hands, the green dragon stick in his left hand entered the old man's back, and his right hand clenched his fist and hit the old man's flank fiercely!

With a soft sound, the blade of the pen accurately pierced between Leng Aotian's two ribs, until it was stalkless, and then pulled out, the angle was slightly upward, and it stabbed again, Leng Aotian did not dodge or dodge, and let it pierce into his body. Leng Aotian's blue compound eyes stared at the old man deadly, threw away the green dragon stick, and the green dragon stick was cumbersome in the close-quarters combat at zero distance, his hands flew one after another, and his fists frantically hit the old man's body, and each punch frantically destroyed the old man's vitality with the power of the seal! At this time, the two of them are like hooligans fighting in the market, they can't talk about any skills or abilities at all, they just slash each other frantically, relying only on instinctive reactions to try to attack each other's vital points to see who is the first to fall without support.

The old man suddenly twitched, Leng Aotian saw the opportunity, grabbed the old man's neck with his right hand, crushed the old man's throat, and smashed it on the ground with all his strength.

The old man's right hand was raised in the air, but he no longer had the strength to stab it. He looked at the sharp thorn of his pen blade, which was less than five centimeters, and then at the fact that there was nothing in Su's hand, and muttered in his throat, wanting to say something, but a large foam of blood poured out of his mouth, blocking all syllables. The old man's eyes were full of anger and unwillingness.

Leng Aotian immediately transformed into an all-round form, and although he couldn't regenerate immediately, he stopped the blood from flowing out. Then he calmly walked into a nearby classroom and closed the door.
