Da Da...

The roars of one after another were gradually covered by the sound of rain colliding, Ye Chen bent down, a melee in one hand, and his eyes were facing the staircase on the second floor.

Ye Chen's movements were no different from No. 4, slow and light, silent, and even the subtle wind resistance sound was weakened to the point that it was imperceptible to the naked ear.

No. 4, who was walking on a staircase, suddenly raised his head, and faintly, he felt a trace of existence that did not match the surrounding environment, this should be Ye Chen, but this feeling was a little different from the past, he had the illusion of a hunter and a prey interchange.

However, he quickly dispelled this ridiculous thought, and his vision was dark, this illusion may have been the shock caused by Ye Chen's shot earlier, which made his heart not be able to completely calm down.

As he stepped one step at a time, he could feel his heartbeat accelerating, reaching an intensity that he could barely hear, it was definitely not an illusion, it was an instinctive overdrive reaction to danger, it hadn't been stirred up for years, and he didn't want to believe it.

Four's neck sped up a few bits, but it was so dark that there wasn't even a glimmer of light, and there were no holes in it, and there wasn't any sniper rifle aim, and Four didn't want to let the infiltration turn into a swagger until he was completely sure he was discovered.

Under Ye Chen's infrared vision, although he couldn't see No. 4's expression, he could somewhat guess what he was thinking at the moment, there was a wall here, unless No. 4 had infrared vision or clairvoyant eyes, otherwise no matter how big his eyes were, it would be impossible to find Ye Chen.

Although No. 4 was strange, he still restrained his heartbeat as much as possible, but he was nervous, and even the muscles in his feet bulged out a lot, and he could burst out with strong strength at any time.

After a few stairs in a row, No. 4 had already reached the corner, and even he couldn't restrain his abnormally beating heart, at this moment, No. 4 suddenly flashed in front of him, and subconsciously stretched out a knife to block, but in an instant, he could hear the harsh sound of metal colliding.

Ye Chen's right foot strides forward, and the melee in his left hand has perfectly collided with No. Four's knife, and at the same time, Ye Chen's left foot is forward, and the melee in his right hand also swung towards No. Four's neck without hesitation.

At the corner of the narrow staircase, the speed of the fourth could not play a real role here, and in desperation, he had to retreat sharply.

However, in such a dark night, without visual reinforcement, Four, while retreating, developed a word called imbalance in his body, which he had not experienced for many years.

No. 4's body retreated quickly, but after receiving Ye Chen's move, the balance of his body weakened, and after a few stairs in a row, he stepped directly into the air and fell to the first floor.

Falling like this would naturally not bring any injuries to Number Four, but for his heart, it was a blow, and he seemed to be able to feel Ye Chen's mockery, although Ye Chen still had that indifferent expression.

No. 4's reaction exceeded Ye Chen's expectations, he originally thought that the second knife would at least have some results, but he didn't expect the other party to retreat directly, making the second knife empty.

Ye Chen didn't move, just stood quietly at the corner of the stairs, No. 4's speed was much faster than him, once the space where he could use his hands and feet became larger, No. 4's advantage would make Ye Chen very uncomfortable, he didn't want to be cut by No. 4's venom-stained knife.

The assassination failed, but was attacked by a sneak attack, this is the first time in the history of the fourth, when he carried out the assassination, he was unusually calm, and alert, just a small failure, it brought him great frustration, the fourth has a perverted state of mind, at the moment the occupational disease makes him rational at the same time, the fire in his heart is also burning.

On the one hand, Four couldn't stand the frustration, and on the other hand, Four also knew how to take advantage of it, so the two of them looked at each other across the stairs of no more than ten steps.

Ye Chen had time to accompany him to consume, except for No. 4, he believed that no one knew the situation here at the moment, Ye Chen was quite alert to danger, and after making sure that he was not discovered by several other company personnel, he could play a protracted battle with him.

Combat, especially kills in melee combat, can speed up the rotation of that unknown vortex in the body, resulting in mutation points.

As an assassin and killer, No. 4 has always been very calm, and Ye Chen, as a sniper, is even more able to calm down as a calm fighting machine, the two look at each other, although even the contours of each other's faces can barely be seen clearly, but they can still feel each other's fighting intent.

Ye Chen is already a third-level speed enhancement, and he has the auxiliary talent of speed control, as for infrared vision, it can be used when he sneaked up on it before, it is really a melee fight, and it is useless.

Ye Chen's calmness was a bit beyond the expectations of No. 4, it stands to reason that he came to a team this time, the longer the battle, the more unfavorable it was to Ye Chen, although he couldn't see Ye Chen's expression, and even his eyes couldn't see clearly, but No. 4 could still feel Ye Chen's immobile composure.

Of course, No. 4 knew that there would be no helpers in this battle with Ye Chen, at least it was impossible for him not to take the initiative to send a signal, but this did not mean that Ye Chen also knew, I have to say that Ye Chen's calmness made No. 4, who was already in a bad mood, even worse.

As a professional assassin, when he was in an unstable mood, he had already failed, No. 4 already had the idea of superiority, and dozens of missions without failure cases made him arrogant and conceited, in fact, he did have the qualifications to be arrogant, but the opponent he met this time was Ye Chen.

The two looked at each other for only a minute or so, and the always calm No. 4 didn't know what he was thinking, and rushed towards Ye Chen with a knife, although his memory ability could not reach the level of a master, but he who had practiced it himself, it was impossible for him to step on the ladder and guess wrong.

Ye Chen seemed to have anticipated this situation a long time ago, he was not in a hurry, he stood still and did not move, in fact, this staircase was only the width that could accommodate two people, this was the only place where Ye Chen could reduce the speed advantage of No. 4, he could only fight No. 4 here, and the rest of the place, Ye Chen would suffer a lot.

No. 4, who has a fourth-level speed enhancement and second-level strength enhancement, in the face of Ye Chen, who has comprehensive development, he has advantages and disadvantages, and now Ye Chen has continuously reduced his advantages, and No. 4 does not know how to advance or retreat, so even if he loses, it is his own problem.

As an assassin, after exposing his whereabouts, his first thought should be to retreat, but No. 4 is different, he has fought with Ye Chen once, whether it is Ye Chen's speed or strength, he is confident that he can defeat him, since he can be sure of victory, why should he retreat.

Knock, knock, knock, with three powerful stomping sounds, No. 4 appeared in front of Ye Chen, even if there was not much room to stretch his skills here, No. 4 was sure to tear Ye Chen apart, as for the task of capturing him alive, he had already left it behind.

Number Four is calculative and calm about the target of the hunt, but there is a clear difference between him and the current young man who is short-tempered and has to wield a knife at every turn.

This scene, Ye Chen didn't expect, but this is a scene he likes to see, the corners of Ye Chen's mouth are slightly raised, and the curve with a curve makes his left face slightly bulge, at the same time, Ye Chen's left and right hands are used, and the fourth with a speed advantage is even worth two knives against Ye Chen, if it weren't for the narrow corridor, Ye Chen might have to exchange injuries for injuries to be able to fight with him.

Ye Chen waited for No. 4 to be half a meter away before making a move, and in No. 4's eyes, Ye Chen seemed to have no time to react, and he was even more contemptuous of him in his heart, and as for the shame of falling before, it was no longer so annoying.

Ye Chen's right foot stepped heavily, and with a roar, the wooden staircase couldn't help but tremble, and his left and right hands were even used differently, wanting to use it to block No. 4's fast knife.

When the assassin turned into a frontal warrior, the result was not as simple as Ye Chen thought, No. 4 was proficient in all kinds of assassination, and at the same time had rich training in frontal hand-to-hand combat and frontal knife combat, but he rarely had actual combat experience in this area, after all, the prey he picked had no chance to fight him head-on, Ye Chen was the first to avoid his assassination.

The quiet ruined building, full of the sound of metal colliding, Ye Chen's snort was a little faster, and his body was constantly retreating, No. 4 was much more difficult to deal with than he imagined, even if it weakened a lot of advantages of No. 4 in the corridor, but the fourth-level speed enhancement was really not as simple as numbers.

After only a minute of fighting, there were several more blood marks on Ye Chen's lower abdomen, and the No. 4 knife was made of unknown materials, and it was so sharp that it just rubbed against Ye Chen's sweatshirt, and the opening was cut, and the venom on the tip of the knife entered Ye Chen's body through the wound.

The No. 4 knife was smeared with a deadly toxin, for ordinary mutants, three seconds of neurasthenia, one minute was enough to be fatal, but this toxin met Ye Chen, as if he had met a natural enemy.

While No. 4 was surprised at why Ye Chen didn't die for a long time, Ye Chen's speed did not weaken, but became faster and faster, No. 4's advantage was a quick victory, and a lethal blow, he was not suitable for protracted combat, a few swords did not bring a fatal effect, No. 4's mentality couldn't help but have some effects.

In fact, unlike what No. 4 thought, Ye Chen was not immune to deadly toxins, but his body was constantly rejecting external factors, this was not talent or ability, this was Ye Chen's innate, just like flowing blood, everyone was born with it.

The unknown gene in Ye Chen's body is extremely domineering, whether it is a toxin or what, as long as it flows into his body, it will be rejected or accepted by this mysterious gene, acceptance is equivalent to fusion, becoming one, rejection, it will become gas and be discharged from the body, so far, Ye Chen has never really been poisoned, but he knows that he is not immune to toxins, but his body has made adjustments on its own.

Ye Chen didn't know if this was good or bad, if you look at it from the perspective of the battle, this will definitely be more beneficial than disadvantageous, but whether this has side effects or not is indeed a mystery, no matter who it is, they don't like to have an invisible bomb in their body and suddenly explode when you are the happiest.

If you insist on treating this effect as a talent, it can be called divine healing for the time being, a passive effect.

In fact, when the body rejects external factors, it has an impact on Ye Chen's actions and thinking judgments, and No. 4 thinks that it has no effect because his movements are slowing down, as a fast and high-explosive combatant, No. 4's body is only compatible with fast combat, once he is overloaded for too long, his speed will continue to weaken, and even his reaction ability will regress.

In other words, while Ye Chen's combat power was retreating, No. 4 was retreating at a faster speed.

With the narrow environment, Ye Chen was gradually able to keep up with No. 4's movements, although No. 4's movements were fast, but if he wanted to give Ye Chen a fatal blow, he couldn't do it, he could only keep adding more wounds to Ye Chen, but the ending was not ideal, at least he felt that Ye Chen was like a tiger, and the more he fought, the more fierce he became.

When No. 4 shifted from the opponent's problem to his own problem, he had no time to make adjustments, No. 4 had a natural self-confidence in the enemy, on the one hand, the strength was suppressed, and on the other hand, he won all battles, causing him to not check his physical condition at all, and only when he was weak, he reacted.

No. 4, who got out of his heyday, is no longer to be afraid of Ye Chen, but the other party wants to leave, he can't stop it at all except with a gun, but No. 4 not only doesn't want to go, but also wants to kill Ye Chen alive, No. 4 is not calm in his heart, and he feels the strangeness of his body, and it is like a thousand shames, and in an instant, he almost lost his mind.

No. 4's speed and strength increased at the same time, Ye Chen was a little in a hurry, after determining the true situation of the other party's body, Ye Chen was a little relieved, over the years, he has encountered a lot of assassins, but like No. 4, the general trend has gone, and there is really no retreat, Ye Chen doesn't know whether to admire, or think he is stupid.
