The system is four years ahead of schedule, but Weird is still a cub.

Yang Yuxin and Yoona reacted very quickly, protecting Cheng Shengnan behind them at the same time, and then attacked the ghost face on the wall. The strange knife and the monster's sharp claws scratched across the wall, leaving several blood marks with a "puff" sound, and the next second, black sticky substance flowed out of these blood marks.

Upon closer inspection, it was indeed those black worms again.

"The strength of its strange power is not high, and it is not the fused monster that controls this strange space." Although Cheng Shengnan also has a certain combat ability, going forward to help at this time would only cause trouble.

Fortunately, she also had self-awareness and left the battle to the professional Yang Yuxin and Yoona, while she tried to stay back but not away from the two of them, looking for strange weaknesses through the strange energy detector.

Under Cheng Shengnan's command, Yang Yuxin skipped the step of checking the detector and focused on dealing with the weirdness. Together with Yoona, they quickly broke through the wall with the help of weird energy equipment.

A big hole was blasted into the wall, the ghost face was incomplete, and its bloody mouth was pitch black, as if there was an independent space inside.

"Gulu."

"Gulu."

A strange and unique swallowing sound could be heard faintly in the dark space. Although the situation in front of him was very strange, this was the only way in front of him. It was not right to go, and it was not right not to go.

After discussing it, the three of them decided to move forward.

Yang Yuxin walked in front, Cheng Shengnan was in the middle, and Yoona was responsible for covering the rear.

Cheng Shengnan followed Yang Yuxin with a serious expression. He didn't dare to make any sound at this time because he didn't know what this strange dark space was like. The appearance of the ghost face on the black wall gave people the illusion that they were entering its belly.

But there is another fused monster inside the body of the fused monster. Even Shen Ge has never encountered such a situation, so Cheng Shengnan judged that the ghost face wall just now was a kind of existence similar to the "gate" of the throat. Passing through that door means officially entering the interior of the fused monster.

After walking for about ten minutes, in this pitch-black space, the light from the flashlight provided even less visibility.

The strange thing is that after walking into this area, the ground felt soft when stepped on, as if it was covered with a thick layer of mat.

The surroundings were dark and quiet, so quiet that it was eerily quiet. Apart from the occasional swallowing sound, the only sound I could hear was my own breathing.

Cheng Shengnan subconsciously slowed down his breathing, and Yang Yuxin also subconsciously slowed down her breathing. However, it was not because she felt the invisible sense of oppression in the dark space, but since entering this space, she felt that the strange creature making the swallowing sound was near her.

"Did you hear any sound?" Yang Yuxin asked.

Cheng Shengnan replied: "It's a strange swallowing sound. I feel like it's near us, but the strange thing is... the distance seems to be getting closer and farther, and I can't even tell where it is exactly."

"Did you all hear the strange noises? But why didn't I hear anything?" Yoona said with some confusion.

Yoona was not intentionally adding to the fear of the two girls at this moment, but she really didn't hear any sound since she entered the dark space.

Cheng Shengnan and Yang Yuxin also felt very strange when they heard this. They also knew that Yoona would never joke at this time. For a moment, they couldn't help but think of the situation in front of the black wall of ghost faces.

At that time, Cheng Shengnan felt the cold first, Yang Yuxin had to remove the protection of the weird leather suit before she could feel the cold, and Yoona felt nothing.

In other words, this strange effect seems to only work on humans.

"It's strange energy! There is invisible strange energy in the air, and this strange energy will have a certain impact on humans, so Captain Yang and I can feel the changes around us, but Yoona can't feel anything!" Cheng Shengnan immediately realized the problem.

Yang Yuxin's eyes darkened, and she immediately took out a strange gas mask from her backpack and put it on. In an instant, not only did the vague feeling of chill and oppression decrease slightly, but even the strange swallowing sound that came and went became much smaller. It seemed to be within a few meters before, but now it seemed to be dozens of meters away.

Yang Yuxin discovered that the strange gas mask was effective, and immediately took out a spare one from her backpack and handed it to Cheng Shengnan to wear. Cheng Shengnan immediately experienced similar effects as Yang Yuxin, and the strange negative effects faded.

"It seems that this should be the fusion monster in the monster files recorded by Shen Ge, whose strange energy effects can cause hallucinations and negative effects on humans. This kind of fusion monster has a strong mental attack power, and the closer to the heart area, the greater the impact." Cheng Shengnan said in a deep voice.

As soon as these words came out, Yang Yuxin's eyes suddenly became solemn. If it was true as Cheng Shengnan said, then it meant that even with the strange energy gas mask and strange leather battle suit, it would be difficult for her to get close to the heart.

The reason why Shen Ge can freely enter and exit the body of the fused monster without being affected by the erosion of strange energy is largely because the original strange cells in his body resist the erosion of strange energy.

Weird power is only harmful to humans and will only affect humans in some aspects. This is why if a monster wants to control weird power, it must implant weird cells.

"If... the weird power only affects humans, then can't you just let me find the weird heart, or go to the place where you can no longer resist the erosion of the weird power?" Yoona suddenly said. At this time, she had completely controlled the weird cells and was no different from the monsters in the monster organization.

Therefore, compared with these fusion monsters, her rating is actually higher, so it is not surprising that she can resist the erosion of strange energy.

"This is indeed a method, but we are not sure about the strength of the fused monster's 'heart', and whether there are any parasitic strange creatures around." Yang Yuxin said in a deep voice.

Cheng Shengnan said: "From Shen Ge's records, both of them exist. Even some powerful fusion monsters will actively generate weird and weird people for defense when they encounter danger. The heart is the weakness of the monster, and it is also the most defensive place."

"That's right...but Director Li conducted multiple simulations based on the report brought back by Detective Shen and created a strange energy bomb that can neutralize strange energy. This strange energy bomb can destroy the strange and hard defense to a certain extent, and may even be able to blow up the heart's defense." Yang Yuxin said.

Yoona asked, "Do you have this kind of weird bomb?"

"Yes, but there is only one." Yang Yuxin had no experience fighting against fusion monsters, and had never thought that one day she would fall into the stomach of a fusion monster. The only neutralizing energy bomb in her backpack, which was aimed at the "heart", was just a "precaution."

Yoona said, "Let's decide this first. Everything is based on finding the heart. We'll make a decision based on the situation. If you can't resist the erosion of the strange energy, I'll take the neutralizing strange energy bomb into the heart and try to blow it up."

"But..." Cheng Shengnan hesitated, "As far as I know, the biggest reason why the neutralization-type weird energy bomb can blow up a heart with extremely strong defense is that it can integrate the weird energy of the heart's defense to produce a twisted vortex, thereby creating a gap. Although you are now a monster and will not be affected by the erosion of the heart's weird energy, it is precisely because you are a monster that the twisted vortex generated by the explosion of the neutralization-type weird energy bomb is likely to pull you in." Yoona smiled slightly and said, "Having said that, there is no better way right now, right? What's more, my mission is to protect you. Besides, Shen Tan saved my sister and me from hell. How can I let his beloved get hurt with such a great favor."

"But it was him who saved you, not me. You don't have to sacrifice yourself for me. Besides, creating a distorted vortex does not mean that your heart is damaged. Your condition may also be affected by the distorted vortex, so I think the safest way is to enter that area together." Cheng Shengnan said.

Yang Yuxin echoed, "Director Cheng is right. The neutralizing energy bomb will also have a certain effect on you. If you are implicated after the explosion, no one will continue to destroy the heart and defeat the fusion monster. But it's useless to say more now. At least we have to wait until we find the heart."

As the three of them were talking, they walked forward for nearly twenty minutes. At the end, they saw another black wall. The difference was that there was a strange "door" in the middle. It was clearly two sliding doors close together, but they were irregular and looked like the shape of a "heart".

"This fusion weirdo is quite considerate. He was afraid that we couldn't find the heart, so he made the 'door' into a heart shape to make it more recognizable?" Yang Yuxin couldn't help but complain.

Yoona said seriously: "It might be a trap, be careful!"

"..."

Yang Yuxin made a casual complaint but the other party took it seriously. For a moment, she didn't know how to respond. In the end, she could only turn her words into action and approached fully armed in her weird leather battle suit.

Yang Yuxin tried to push the door, but no matter how hard she pushed, the door didn't move at all, as if she was facing a wall instead of a door.

"Alas. We were arguing before about who should sacrifice to enter the heart and detonate the neutralizing weird energy bomb, and now a mere door has blocked us." Yang Yuxin chopped the door several times with the weird energy knife, but the door did not move at all, and not even a knife mark was left, which made her speechless.

You can't use the neutralizing weird bomb on this, right?
"I have a solution." Cheng Shengnan said.

As soon as these words were spoken, Yang Yuxin and Yoona turned around at the same time to look at Cheng Shengnan who was standing behind them, only to see her patting her wrist and then "reaching" her right hand into her left wrist.

Her right hand seemed to have entered another space and "disappeared" in a very strange state. This scene immediately stunned Yang Yuxin and Yoona.

Yang Yuxin said excitedly: "Could this be the latest model of the strange energy backpack announced by the research department before, a blood-skin backpack that can unfold a small strange space?"

Currently, the Rong City branch, or the entire Special Policy Department, has only one blood-skin backpack, which is integrated with the red fog armor and is used by Shen Ge.

Although researchers led by Li Xiang from the Rong City branch have tried many times to find inspiration from the strange energy cells and "para-armor" to create something similar to a space backpack, they have always ended in failure.

Seeing something similar in Cheng Shengnan's hand, Yang Yuxin was extremely excited. If her combat backpack could be replaced with a space backpack, she could carry several times more weapons and ammunition, and she would no longer have to worry about insufficient explosives.

"In fact, it is just a product split from the blood-skin backpack. The actual space is not large, only about a dozen cubic meters." Cheng Shengnan said, taking out a strange energy rocket launcher from the blood-skin backpack and carrying it on his shoulder.

Shen Ge taught me, when in doubt, try RPG first!

However, Shen Ge's original words were "When in doubt, take the first shot", but Cheng Shengnan automatically filtered out some inappropriate situations.

"..."

"..."

This scene stunned Yang Yuxin and Yoona. In their eyes, Cheng Shengnan had always been an intellectual, OL-style civilian, and it was hard for them to accept her sudden transformation into a female Rambo.

Under the subtle gazes of the two women, with a "whoosh" sound, the rocket launcher dragged a long tail of fire and flew towards the heart gate in the distance, and with a "bang" it exploded a wave of fire.

Seeing the fire wave rushing towards her, Yang Yuxin immediately stepped forward, raised her hand, opened the strange leather arm guard, inflated it to form a large air cushion, and blocked the air wave.

The air cushion inflated by this strange energy arm guard is filled with strange energy instead of ordinary air, so it will not explode even if subjected to strong impact and high temperature.

When the fire wave dissipated, the three men came to the door and saw a small gap blown out on the "door".

Yang Yuxin did not bring large weapons such as the Strange Energy Rocket due to carrying capacity issues, but she knew that the power of the Strange Energy Rocket was no less than that of ordinary Strange Energy Grenade, and was even several times more powerful.

This shot only made a small gap, which is enough to show how strong the defense of this "door" is. If a door is like this, how hard must its "heart" be?
In fact, Cheng Shengnan felt a little disappointed when he saw that the strange energy rocket only blew a small gap. After all, when he was sitting in the office reading Shen Ge's heart-moving reports, he could always easily kill those high-level fusion monsters and make them disappear into ashes while chatting and laughing.

But when they got their hands on it, they found that it was just a suspected fourth or fifth level fusion monster, which left the three of them at a loss.

It was not until this moment that Cheng Shengnan truly understood that the "terror" that Shen Ge had experienced could not be resolved by just a few words from him.

At this time, strange energy black fog continued to pour out from the small gap blown out on the "door". When the strange energy black fog spread, Yang Yuxin and Cheng Shengnan suffered serious mental attacks even though they were wearing strange energy gas masks, causing them to have more and more "auditory hallucinations".

With her strange body, Yoona took the initiative to approach the gap, and then she found that the "door" was like a thin film, like a protective shell to protect the "heart". But such a thin layer of protective film could actually block a rocket!

Then Yoona shone the flashlight towards the gap. The flashlight light appeared to be a "wall of flesh" half a meter away. Upon closer inspection, the wall of flesh was actually beating "thump, thump".

"Heart! I saw the heart!" Yoona said excitedly.

However, more and more strange black mist poured out of the big hole in the door. Cheng Shengnan, who had weaker defense, felt that her head was about to explode. The strange "gurgling" swallowing sound was like thunder exploding in her ears, making her head dizzy and her consciousness blurred.

Realizing that Cheng Shengnan was not in good condition, Yang Yuxin tried to take her away from the influence of the strange energy black fog, but the strange energy black fog spread too fast.

"Captain Yang, give me the neutralizing type weird bomb! Quick!" (End of this chapter)
