In a secret passage deeper under the underground complex, the figure of a teenager was running hard—it was Su Mu who was about to rush to the interrogation room to meet his friends.

He'd been running like this for five minutes since he got into the place where he couldn't see his fingers. In order to conserve his physical strength and deal with the battle that could happen at any time, Su Mu deliberately slowed down his speed very slowly (relative to the extreme speed he could achieve so far), although with his current physique, even if he ran at full strength for a long time, it should not have much impact on the battle.

After entering this secret passage, the wireless communication between Su Mu and his partners was interrupted, so he had no way to determine whether his partners were already waiting for him in front, so he could only roughly determine that after this section of the road, the distance between the so-called interrogation room and himself was being rapidly pulled in, and it was soon close in front of him.

Just when Su Mu thought that he could reach the exit smoothly like this, a strange feeling came from directly in front of him, as if ...... It's like I'm being stared at by something.

Su Mu concentrated on the road ahead, trying to find the source of this strange feeling, but there was only darkness everywhere he looked.

Su Muzhen wished that his combat suit was equipped with lighting equipment as standard, but the truth was that he didn't even have a small flashlight, not to mention a small headlamp.

He felt like he had just made eye contact with that thing, he didn't know what it was, but he could feel the sight of the thing.

Su Mu stopped, quietly waited for the thing to come, and then took the AA12 that had just been used not long ago from his back, and now there were almost half of the drums of shotgun left on this gun, which was undoubtedly more than enough to deal with the enemies encountered in such a narrow area, and this gun was powerful enough to spray anything hostile at close range.

As the distance drew closer, a vague humanoid silhouette emerged at the end of the field of vision. Due to the total darkness, the thing almost blended in with the background, and it wasn't until it was almost about to walk in front of it that Su Mu recognized what it was.

The whole body is pitch black, there is no tangible body, and black smoke is rising...... Isn't it the Shadow Servant who never appeared in the battle just now?

It seems that the captain's proposal has finally been approved by the "Lord", and some of the Shadow Servants who do not need to be stationed in place in principle have been transferred to serve as a new force in the search for intruders to supplement the lack of manpower. Although Su Mu himself felt that it was more likely that their adults couldn't stand the extremely low efficiency of their subordinates......

I saw that the shadow servant slowly approached with a long knife, although they were called shadows, they did not have the ability to turn into shadows and shuttle freely, and being able to enter this secret passage meant that there must be an exit ahead, but if Su Mu wanted to go out and didn't plan to return the same way, I am afraid that he would have to defeat the guy in front of him.

At this point, Su Mu naturally knew in his heart, he didn't plan to retreat from the beginning, after all, it was not easy to get out from under the hands of those bastards, where is the reason to drill back again?

Perhaps sensing Su Mu's hostility, the shadow servant immediately raised the big knife and stabbed straight at Su Mu's chest without fear of death.

Su Mu didn't dare to hold it up, and sprayed three shots in succession at the only black clothes on the other party's body, that is, the thing it was attached to.

The bullet effortlessly pierced through the clothing, piercing the front and back, but it did not stop the servant's momentum, and the long knife did not slow down at all, stabbing straight and firmly at Su Mudang's chest.

Seeing that the situation was not good, Su Mu slid backwards with a sliding step, trying to dodge the spurt.

The blade of the long knife cut through the air and touched the surface of the combat suit on Su Mu's chest, and at this moment, Su Mu also began to evade before the power of this knife was fully exerted.

Due to the weakening of the relative movement, the force contained in the knife only exerted a partial effect, and as a result, the sharp blade could not even break through the resilient surface of the combat suit, and the blow was completely dissolved.

Picking up a life, Su Mu suddenly didn't dare to be negligent in the slightest, and squirted several more shotguns towards the place where the clothes on the slave's body were still connected, completely tearing it in half. At this point, the opponent's actions finally stopped, and gradually dissipated into black smoke and dissipated into the air.

The threat was lifted, Su Mu wiped his sweat, this kind of enemy ignored the impact of bullets on the physical level, which really gave him a big headache, the distinctive impact advantage of the shotgun was gone, no matter who it was, he would feel aggrieved.

However, as he continued to take a few more steps, he was forced to face the battle again - more Shadow Servants emerged from the darkness and gathered more and more!

"Damn, are they all here?" Su Mu gritted his teeth, but it also meant good news: an exit to the surface must be nearby, otherwise there wouldn't be so many shadow guards here.

Thinking of this, Su Mu finally put away the hanging appearance and began to put on a serious posture: his right hand was still holding the gun, but it had been replaced with a new drum, and his left hand pulled out the multi-purpose dagger that came standard with his combat uniform and used it as a deputy. With his legs slightly bent, he stood in a vigilant posture suitable for exerting force at any time.

After accumulating momentum, Su Mu didn't wait for the servants to react, and rushed out with an arrow step, directly announcing the beginning of the battle in the simplest and rude way.

Before the first slave could respond, the clothes on his body were cut off by the trolls in Su Mu's hand from the bottom to the top, and they could only turn into smoke and dust in a silent silence.

The second shadow slave waved the long sword in his hand, blocking the path that Su Mu must pass forward, slashing horizontally, and Su Mu's response was also extremely simple - an iron plate bridge swept under the sword, and the dagger in his left hand cut off the back of the slave's black clothes while getting up.

In this secret passage, which seemed spacious to walk and a little narrow to fight, Su Mu rushed left and right to rush forward, constantly defeating the attacking enemies, with knives in his hands and gunshots, a slave would scatter in all directions. And the next blow will still not carry the slightest stagnation and hesitation.

The distance between him and the exit was constantly narrowed in the process of this rush, and gradually Su Mu could already see a ray of light from the top of his head, which seemed to be a shot of heart booster, directly piercing his heart ventricles.

"Drink~" The two moves put down the enemy who was blocking the way, and Su Mu ran towards the light without stopping......
