This was not Su Fei's random conjecture, because Su Fei himself had participated in the design of the third-level alchemy laboratory throughout the whole process, although this was an underground experimental base, far from being as simple as a laboratory, but the principle was the same.

Su Fei pondered: "The passages in this base are intricate, although Zhang Yuhang has entered the No. 6 area, he can completely reach any other area from here. ”

"So be it. ”

Gong Yang didn't drag his feet in doing things, and with Su Fei taking the lead, everyone quickly decided on the next strategy, but before that, Su Fei also went to the warehouse area, not only loaded with a lot of weapons and equipment, but also asked people to reconfirm all the passages on this floor.

The alloy doors connecting the central hall in the fifth, sixth, seventh, and eighth districts have been completely locked by Zhang Yuhang. After discussion, it was decided to take the No. 4 water source area as the breakthrough point, enter from a passage in the middle of this area, and according to the structural design drawing, after passing through this channel, you should be able to directly reach the middle section of the No. 6 area.

Gong Xiaochang led the four people on the ground to continue to work hard to open the gate, Gong Hua led the people to defend the central hall, and the others all followed Su Fei into the passage.

Hu Mang's sense of smell was the most sensitive, and he walked in the forefront, while Su Fei responded behind him, and Tang Xueyan also followed Su Fei closely. Gong Yang was in charge of the broken queen.

Everyone raised their vigilance to the peak, and although the worst cultivation among them was the peak of the ninth layer of the Zhiwei Realm, which was enough to deal with this kind of scene, the fear of the unknown still lingered in everyone's hearts.

This passage is made up of continuous buffer compartments, and the gates need to be opened one by one. Fortunately, this kind of gate is the most common electronic lock, and everyone was not blocked along the way, and entered Area 6 smoothly.

However, after entering here, everyone's alertness instantly increased to the peak!

The mess is not enough to describe what everyone sees, this has become a graveyard of flesh and blood!

But to Su Fei's surprise, apart from blood and minced meat, there was not a single corpse left around, not even a little bit of minced flesh, not even a broken body left.

You must know that according to Lei Huangding, even if you are bitten and clawed by a primordial nightmare, it still needs the greed accumulated in people's hearts to exceed a certain critical point before it can mutate.

Could it be that all the Zhang family members have mutated into primordial nightmares? No one has been spared?

Su Fei scanned the entire room suspiciously, and then rejected the entire assertion.

Because in the scene, he did not see a white bone spit out by the primordial nightmare, in other words, the body was dragged away by someone, and it did not mutate here.

Sure enough, everyone searched carefully in this room, and soon found numerous drag marks in the bloodstains, and the dark and light lines in the bloodstains extended to another exit of the room.

The dim lights flickered overhead, mixed with the usual crackling of electricity, and the excessively strong smell of blood in the air gave people the illusion of sweetness in their mouths and noses.

The tiger crept forward and pushed open the gate, and in front of him was exactly the same bloody hunting ground.

This is an examination room, but the experimental operation table is messy, the glass on the originally clean ultra-clean workbench has been smashed, and several large glass frosted bottles next to it seem to have stored something before, but at this moment it has been shattered by a huge force.

The floor of the room was the same as before, and there were many bloody drag marks on the floor, which eventually converged with the previous drag marks, like a tributary of a river flowing into the main trunk, and finally the bloody drag marks broke in front of the door, this self-closing negative pressure sealed hatch cut off everything after that......

Tang Xueyan didn't know what she saw, and suddenly hugged Su Fei tightly, and pointed to the test bench in front of her with a frightened face!

Su Feishun's Tang Xueyan's fingers saw through the dim light that there were several fingerprints full of blood on the sturdy corner of the test bench. This man must be trying his best to buckle on the corner of the table, not wanting to be dragged into a deeper hell!

In the end, he disappeared, and at the same time, Su Fei also saw the traces of him being dragged away on the ground, and the ten fingers that were fiercely buckled on the ground made ten shocking finger marks on the bloody ground!

"When they were taken away...... It's alive......" Tang Xueyan began to tremble a little when she spoke, she already had a psychological shadow for this kind of thing, and at this moment, this shadow was infinitely magnified in an instant!

Gong Yang and those Gong family soldiers also noticed this, and their faces became more and more difficult to look at.

Su Fei was a little strange, could it be that he was mistaken? The Primordial Nightmare has never hesitated to parasitize and transform when he sees flesh and blood, when will it leave a living mouth? Could it be that the Primordial Nightmare that is raging here is not the Primordial Nightmare at all?

Recalling the fishy smell he had smelled in the ventilation duct before, Su Fei suddenly shook a little.

"Be careful, this may not be the primordial nightmare, it may also be something else. Su Fei reminded him, patted Hu Mang's sturdy back, Hu Mang understood, and continued to march into the depths.

Room by room to look for the past, I don't know if it was too good luck or too bad luck, they didn't encounter a single monster, but they didn't find the control center in the place Su Fei expected, this is just a hidden warehouse, there are some important experimental materials in it, but it is useless at this time.

Walk to a Y-shaped fork in the road, and the road behind you is marked with the passage on the left that leads to Zone 7, and the passage on the right marked Sector 5.

"It's not a way to drag on like this, let's separate here. Gong Yang said to Su Fei: "Master Su, you take people from this road into Area Seven to find a control center, I will take people from this road to Area Five, if you don't find it, then go back to Area Seven to find you." ”

"Is that okay? It doesn't seem like a wise choice to separate like this. Hu Mang, who had not spoken much, spoke, and he rubbed his blood-stained tiger claws twice on a fairly clean wall: "We'd better go together, otherwise any accident will be in trouble." ”

As he was talking, everyone's walkie-talkie suddenly sounded Gong Hua's cry for help: "Report report, we are under attack, request return support, request return support!"

In addition to the cries for help, there was also the sound of MP5 submachine guns pouring bullets and a roar full of tyranny!

"Primordial Nightmare, so many Primordial Nightmares!

"Request support, request support!"

Su Fei immediately turned around and rushed back frantically along the same path, the area where Gong Hua was stationed was the central hall, and there was the only large elevator that could lead to the ground, if you couldn't hold it, no one would want to get out of this purgatory!

Gong Yang, who was running wildly, roared into the walkie-talkie: "Gong Xiaochang, immediately send someone down to support Gong Hua!

But the sound of response on the walkie-talkie made Gong Yang feel cold all over his body, no one replied, and the sound of bullets frantically whistling out of the chamber of the gun was still in his ears!

"No, I've been attacked here!" Gong Xiaochang threw out a grenade, the violent explosion sound was deafening, Gong Xiaochang had a gap to aim at the microphone and shouted: "The primordial nightmare bypassed the elevator along the ventilation duct, and has climbed to the gate of the experimental base, we are leaning on the door to snipe them!

Su Fei's face was gloomy and terrifying, his plan was all messed up, and the primordial nightmare actually ran out all at once, instantly dividing everyone into three parts that could not be echoed! Now let alone looking for the hidden control center, it is not certain whether he can keep the back road of retreat!

The primordial nightmare seems to have been planned, it has not appeared before, and when everyone goes deep underground, it suddenly runs out and cuts off everyone's back road, which makes my timing simply too good!

If it weren't for knowing that the primordial evil nightmare had no brains, I'm afraid Gong Yang would have suspected that someone was behind the manipulation of all this!

Wait!people?!

Zhang Yuhang?!

Su Fei stopped in an instant, and Tang Xueyan behind him didn't react and almost hit his back!

"Gong Yang, you guys quickly support the above, and I will go down with Hu Mang!" A touch of ruthlessness appeared in Su Fei's eyes, and the true qi of "Taiyan Decision" filled the meridians, making him instantly high: "I'll go find that control center, Zhang Yuhang must be there!"

After saying that, Su Fei began to run back, and Hu Mang followed closely without saying a word, Tang Xueyan was originally a little hesitant, but after gritting his teeth, he still turned around and followed Su Fei!

"Auntie, you have to protect me and don't let me be dragged away by monsters!"

"Then what are you doing here? Su Fei looked back at Tang Xueyan, who was following him closely: "Hu Mang and I are enough to deal with it, you go back and go to the ground with Gong Yang, it's safer there!"

"Don't, I'll follow you, there's a place for you...... I just feel safe......" Tang Xueyan's pretty face was white, obviously still a little scared, but her body chose to follow Su Fei for the first time.

Unconsciously, this choice has become Tang Xueyan's instinct.

…………

Returning to the Y-shaped fork in the road again, before Tang Xueyan could ask them whether they were going to District 5 or District 7, Su Fei turned directly to the passage to Area 7.

Su Fei had a strong feeling in his heart at the beginning, that control center must be somewhere in Area Seven.

After entering No. 7 and running forward, Su Fei suddenly heard the same friction sound coming from the ventilation duct above his head!

"Be careful!"

Su Fei only had time to give a warning, and the ventilation pipe above his head exploded in an instant, and more than a dozen primordial nightmares jumped down from the ventilation pipe, opened their blood basins and roared and rushed towards Su Fei who was rushing to the front!

A fishy smell like the deep sea immediately hit my face!
