The explosion seemed to come from deep underground, but the sound was muffled by the distance, and a strong shock wave could be felt from the location of the elevator shaft, causing the air to vibrate violently, rushing up and hitting the metal door hard.

The guys below just turned and ran away, not thinking about whether it would be useful to do so, the explosion effect of the four grenades was limited, but when the flames stuck out of its tongue and engulfed the ceiling and everything around it, they really felt that the lethality of the grenades, shrapnel and shock wave were only part of it.

The terrifying energy hidden in the flames completely engulfed them, making them feel a piercing pain in the exposed skin on their bodies, as if they had been stripped alive, and then even the skin wrapped in clothes hurt.

They opened their mouths wide and wanted to scream, but as soon as they opened their mouths, the scorching flames were sucked into their lungs, licking the fragile airways inch by inch, causing severe secondary burns in an instant.

Zhang Han leaned on the door and listened to the movement below, but he couldn't hear anything, and looked at the six sons and them with a frown, "It's not all blown up, right?" ”

Liuzi shook his head, "It shouldn't be, eighty percent of the trachea was burned by the high temperature, which can easily happen in narrow places." ”

At this time, Ning Xiang looked at the laptop screen and said, "A communication signal was intercepted, and the little devil seemed to be asking for help outside." ”

Zhang Han knocked on the metal and said absentmindedly, "Send us down." Don't let go of any signals, I don't want to be disturbed by anyone tonight, so I have a good time. ”

"Understood!" Ning Xiang looked at the display, her fingers tapped on the keyboard, and the signal was immediately cleared.

After a while, the metal was reopened, and there was still gunsmoke inside, and the entire inner wall was slightly protruding a little, which showed that although the power of the grenade was limited, it was a grenade after all.

"Chen Peng and the girl are sick, you two stay to ensure the safety of Ning Xiang." Originally, Zhang Han didn't plan to let the two of them come, but with the addition of a condensing incense, he had to consider the safety of this little girl.

"Understood."

The two agreed, pulled out their pistols and appeared next to Ning Xiang one after the other, Zhang Han jumped into the elevator, stepped on his feet hard, and found that it was still very strong before he put his mind at ease.

"Let's go."

Ning Xiang knocked on the carriage, and the elevator slowly descended again, and when it came to the bottom, there was a gurgling sound under his feet, as if it was some kind of falling device.

"Ding......

A crisp and pleasant voice came out, and several people stepped out of the elevator and saw several corpses lying in the corridor, all of which were burned to the ground, and the clothes on their bodies shrunk into a ball and stuck to their skin, like silkworm chrysalis bound by a cocoon.

Zhang Han looked at those guys whose bodies were still twitching and were not completely dead, and the corners of their mouths hooked up and said,

"Looks like you like this gift."

Bloodblade looked worriedly at the corridors on both sides, and there were many corridors interspersed with them, which seemed intricate, and it was easy to get lost or spin in place.

"It seems to be a very large space here, where should I find the master?"

I couldn't answer this question, so I could only look at Zhang Han with a see-for help,

"What should I do?"

Zhang Han pressed the headset, "Help us see if there is anything suspicious about this underground laboratory?" ”

There was a crackling sound of the keyboard in the headset, and after a few seconds, Ning Xiang said, "There are a lot of labs and strange rooms. ”

It seems that Ning Xiang can't help at all in this matter.

"What strange room?"

Ning Xiang frowned and looked at the collective map of Sanwei, "The satellite can't scan it, it means that it is made of all-metal, so I don't know what it is, but it should be a very important thing, otherwise it wouldn't be so troublesome, and a room with an all-metal structure will be built one hundred and fifty meters underground." ”

"Got it."

After speaking, Zhang Han said to the Blood Blade and Youmeng, "It seems that we have split up, you go over there to find your master, let's go here to find it, ask Ning Xiang if you have any questions on the road, and use the headset to contact you after you find it." ”

The two nodded, and Zhang Han asked Liuzi to go all the way with them, so that it could be safer.

After the two groups of people separated from here, they went to both ends of the corridor, and Zhang Han went straight to the strange rooms with a vague route in his memory.

Walking through a corridor, the sound of incense suddenly came out of the headset,

"There's someone up ahead, seven guys around the left corner, automatic weapons, military men, walking towards you, and it's expected to run into it in twelve seconds."

Zhang Han didn't have any expression on his face, and when he heard Ning Xiang's words, the dog's eyes looked at each other, and one by one came to the front of Zhang Han, moving forward in an inverted triangle formation.

Sure enough, twelve seconds later, ten guys in military uniforms suddenly appeared at the corner of the corridor, and the front rank was not small.

The two groups of people suddenly looked at each other, and the other party was stunned, just now they received a message that they were asked to go to the elevator shaft to reinforce the security forces, but they didn't expect the guy who broke in to arrive here so quickly.

Zhang Han waved his right hand in the air, driving the wind into the air, attracting the attention of the officer at the front, his eyes were fixed on the object flying into the air, and almost as soon as he found out that it was a knife, he felt an afterimage flash in front of him.

With a whoosh, Zhang Han had already reached behind him, stretched out his hand to catch the exorcism, right in front of the officer's eyes.

The other party's face changed, and he screamed in his heart that it was not good! He wanted to turn around, but suddenly he felt a pain in his neck, and he felt that something cold and cold was thrust into his throat, and the arteries and blood vessels had been cut.

The people behind reacted and just wanted to pull out the gun, Zhang Han quickly turned around, the red light flashed in his eyes, and a fierce murderous aura suddenly swept the entire space.

Turning around, the three people in front of him widened their eyes and covered their necks, staggered back two steps, and then a large amount of blood spurted out of the officer's neck at the same time, and there was a snort of a deflated tire.

Zhang Han solved the four people in an instant, and Erxi dog-eye rushed over with an arrow, stretched out his muscular arms respectively, buckled the necks of the two guys, pulled out the saber on his waist, and slammed it into the back of his head.

The sound of the cervical vertebrae being cut off, along with a piece of the brain stem being cut off, the two guys were killed in an instant, and the two threw away the corpses in their hands like garbage.

The officer's hands were clutched around his neck, staring at Zhang Han's eyes as if he didn't accept the sudden scene at all, and he didn't accept that he was dying, but the darkening sight, and the soft body that couldn't stand on his feet, didn't care whether he accepted it or not, the god of death had already grabbed his legs and pulled hard, and this guy fell to the ground and was completely dragged into hell.

There was only one guy left, so frightened by the sudden scene, that he forgot to run away, forgot to draw his gun, and was so stunned.

The three of them wiped the bloody dagger on the corpse's clothes, and then looked at each other, Zhang Han waved it in front of him with his hand, but he didn't react.

"Smack."

The dog's eyes are a slap without saying a word, as if his slap is a panacea that can cure any incurable disease.

In fact, it really worked, that guy was fanned by the big-eared melon seeds, and his head woke up with a buzz, and Mu Ran looked at the three of them.

Zhang Han walked over and asked in a cold tone, "Tell me, do you know where the Empty Valley Jinlan Pass is?" ”

The other party was very unfamiliar when he heard this name, and the expression on his face was by no means pretended, and he didn't have to wait for him to open his mouth to know that it would definitely be fruitless.

Zhang Han gestured to Erxi, and then walked forward. Erxi suddenly grabbed the other party's head and slammed it hard.

"Click."

The other party struggled at first, but then he couldn't move for a moment, his head was hanging down on his neck, his eyes were staring at the floor, and the black blood flowing from his mouth looked quite disgusting, and he was thrown away like garbage by Erxi.

Passing through two more corridors, there was a dull crash ahead, and a whining sound, which sounded like someone was crying, but the crying sound was strange, not at all like it came from a human throat.

"Call Death, I'm a dream."

Zhang Han stopped and pressed the headset, "I'm the Grim Reaper, what's wrong?" ”

Dream's voice seemed a little nervous, "Something doesn't seem right here. ”

"What's going on!" Zhang Han asked again.

There was silence in the headset for a few seconds, and then the voice of the ghost dream came again, "We found a monster. ”

Zhang Han frowned, "What monster?" ”

"Indescribable, a dead man, limbs and torso attached to a machine."

Zhang Han's brows furrowed even tighter, "What kind of machine?" ”

Gloomy looked at the Grim Reaper, and then at the strange thing in front of him, "Indescribable, like a giant robot, and capable of fighting. ”

"." Zhang Han cursed, biting the dead skin on his lip, it sounded like he had seen this scene somewhere, and it was very familiar.

Press the headset again, "Ning Xiang, hack into their database and download all the experimental materials." ”

Ningxiang's voice came from the headset, "It's already downloading, my hard drive is a little insufficient, and I'm converting cloud storage space." ”

Zhang Han continued, "Do you remember the laboratory on the shore of the sea? I suspect there's some connection here, we may only be getting a glimpse of the tip of the iceberg, and if it's just experiments, then it's already already being made. ”

"Make what?" Ning Xiang suddenly felt a little chilled, do those things in science fiction movies have to become reality? The taste of the little devil is really heavy.

"A war machine that violates human ethics and morality."

Ning Xiang's head was big when she heard it, so she simply didn't ask, and continued to concentrate on downloading all the experimental materials, and then took them back and read them slowly.

Looking for the place where the voice came from, the three of them walked over, a metal door was in front of them, and Zhang Han glanced at Erxi.

Erxi nodded and walked over, stretched out his arm and grabbed the two huge handles, pulled hard, and opened them with a click.

The crying was even more pronounced, and I saw a man sitting inside with no clothes on.
