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

Everyone was a little confused at first, but when they stepped up, they were surprised to find that there really was an invisible "staircase" that they could walk up!

Everyone was wondering how Shen Ge saw this invisible "staircase", but they didn't think that it was something he created.

With the help of the invisible barrier, everyone successfully crossed from the disgusting pool of blood, flesh and mud to the other side, a more open "cave".

However, the walls and ceiling of the cave were covered with disgusting flesh and blood, and the ground was also covered with a thick, fat-like substance, which was extremely disgusting.

Mark's tactical boots stepped on the sticky flesh, and every step made a teeth-grinding sound, making people feel as uncomfortable as a cat's claws scratching on a blackboard.

The beams of the crowd's strange flashlights swept across both sides. The dark red surface of the flesh was covered with earthworm-like blood vessels, which continued to contract and expand with some strange rhythm.

Emily's gas mask let out rapid gasps as she stared at the jelly-like substance hanging above her head. The translucent mucus contained undigested human remains.

Judging from the clothes that have not been digested, there are the same uniforms as those used against the ghost warriors in the first outpost, as well as the clothes of the researchers in this laboratory.

"Ugh..." Emily subconsciously held onto the flesh wall beside her, and her chemical-resistant gloves were immediately corroded and scorched. Mark pulled her away, but found that his palm was stained with sticky yellow pus. Tiny eyeballs were floating in the pus, turning to face everyone.

"How disgusting," Emily said, taking a step back.

When she turned around, she found Shen Ge looking at her. His eyes seemed to be curious as to whether she could really spit it out, which made Emily confused.

"Ah, Captain Shen, what, what happened?" Emily asked nervously.

Shen Ge said it was nothing, but he was wondering in his heart if the other party had seen through something. He hadn't been so "acting" before, but now he was acting like this?

"Don't touch anything!" Mark's strange energy sword split the bulging tumor in front of him. With a puff, dark green juice splashed on the energy shield of the combat suit. At the same time, a body wrapped in protective clothing rolled out of the tumor. That was the symbol of the second reconnaissance team.

The abdominal cavity of the corpse suddenly split open, and hundreds of weird centipede-like parasites crawled out. The sound of their limbs scraping against the flesh wall made people's scalp tingle.

"Stand back and fire!" Mark's roar exploded in the enclosed space.

The moment the parasites were hit by the parasite energy bullets, acid burst out from their exploding shells. An anti-parasite warrior failed to dodge, and the goggles of his protective helmet were corroded and perforated. He covered his face and screamed.

Shen Ge raised his hand, and the strange area unfolded, and a transparent invisible barrier blocked the acid in mid-air.

"Go!" He dragged the wounded and rushed towards the wriggling cavity in front. The flesh wall suddenly secreted milky white mucus. Everyone's feet slipped and they slid uncontrollably like ants swallowed into the esophagus of a giant beast.

Emily's back hit the protruding tumor, and with a click, it turned out to be half of a human mandible, with the teeth still opening and closing nervously.

The next second, she was led by Shen Ge and barely avoided the disgusting flesh tentacles extending from the tumor.

When everyone fell into the area below the open area, the stench was so strong that it almost solidified. Countless intestine-like tentacles hung from the dome of the cave several dozen meters high, and at the end of each tentacle was a half-melted corpse. Barnacle-like parasites emerged from the corpse's eye sockets, spewing out thick black mist of strange energy with every breath.

"Be careful!" Shen Ge's warning was a step too late. A ghost warrior was sucked into the black mist of ghost energy, and tree root-like blood vessels instantly appeared on his neck.

His eyeballs bulged out of their sockets and a strange swallowing sound came from his throat. Mark didn't want him to suffer, so he threw out the strange energy dagger.

Unexpectedly, the dagger pierced his teammate's heart, but the body was still twitching.

The rotten right hand suddenly stretched out to several meters long like a rubber hand, grabbed Emily's ankle below, and the finger bones pierced through the chemical anti-boots and into the flesh.

"Help me!" Emily screamed and fell, and more corpses crawled out of the slime pool. Their spines were bent back into spider legs, and their broken ribs turned into mouthparts.

A red mist armor was attached to Shen Ge's body, and a line of blood extended from it, wrapping around the butcher knife "Indestructible" and flying out, drawing a silver arc of light, and pieces of meat flew wherever the blade passed.

But the severed limbs were still wriggling, and the intestines were automatically joining together like earthworms. The invisible field was fully opened, and the entire area fell into the influence of "collapse" and began to distort. The group of corpses was immediately twisted into a knot by the invisible giant hand. Acid blood fell like a rainstorm, corroding honeycomb-like holes on the shields of the surrounding anti-Ghost Warriors' combat uniforms.

"There's a hatch in front!" Emily limped and pointed to the crack in the flesh wall.

A metallic luster could be vaguely seen deep in the crack, and there was indeed a hatch there.

Everyone quickly covered the wounded and retreated towards the cabin door. Behind the twisted and deformed cabin door was a large sunken pit.

In the center of the spherical space with a diameter of 100 meters, a black heart like a hill was suspended. Its surface was covered with densely packed human faces, each of which was screaming silently. When the heart beat, the skeleton chains wrapped around it collided with each other, making a clicking sound like a death knell.

"Is this the heart chamber of the fusion monster?" Shen Ge's eyes darkened as he looked at the terrifying "heart" in front of him.

The others were not as "calm" as him, and were all frightened by the horrifying scene before them.

"Oh my God..." Mark's strange knife fell to the ground with a clang. The skeletons around the heart were not randomly piled up. Thousands of skeletons knelt devoutly around the heart, with their skulls all facing the center. What was even more terrifying was that the sternum of each skeleton was engraved with an incomprehensible rune number.

"Oh shit!"

"Damn thing!"

"I'll blast you to pieces!"

The piles of bones next to the heart meant that this monster had devoured thousands of humans. Mark couldn't suppress the anger in his heart, so he untied the strange rocket launcher and carried it on his shoulder.

Shen Ge guessed that the strange energy rocket launcher would most likely not hurt the heart, but he did not stop the angry Mark, allowing him to fire the strange energy rocket at his heart.

The heart suddenly contracted violently, spurting out black blood like a waterfall.

In the blood rain, the piled bones were entangled with black blood threads, and there seemed to be many flesh worms wriggling inside. Then these flesh worms gathered together to form a huge tumor, and dark red hyphae grew at the joints. Then the bones "grew" flesh and blood, turning into disgusting humanoid monsters.
"This is..." Emily's weird energy detector suddenly burst into sparks. It was obvious that the weird energy here was stronger than the detector could handle. The beating hearts in the chests of these humanoid weirds were not hearts, but parasitic weirds.

The strange energy bullets and incendiary bombs fired at the strange agents hit the humanoid monster, but the explosion gave birth to more mycelium, which climbed up the chemical protective suits and were drilling into the mouth and nose through the breathing valve.

Seeing this, Shen Ge's invisible strange domain burst out with all its strength. The distorted strange energy released by "collapse" was like a pair of invisible big hands, trying to tear the space apart while grinding the humanoid monster into powder.

But every humanoid creature was reborn after being crushed, and the broken bones were pieced together into more deformed monsters under the traction of mycelium.

The flesh ball made of eyeballs and the centipede composed entirely of teeth were originally strange humanoid in shape, but then developed in an increasingly bizarre direction.

"cough."

Suddenly, blood began to ooze from all of Shen Ge's seven orifices, and even he himself was a little confused by this unusual phenomenon.

"Master, your vital signs have been detected to be declining. The strange cells in your body are releasing strange energy out of control, so human cells are seriously affected." Xiao Qi, who is always calm and composed, actually has a hint of anxiety in his tone.

The fact that artificial intelligence can feel anxious shows that Shen Ge’s situation is indeed not optimistic.

"Is it because of the excessive consumption of strange energy and the inability to continuously provide strange energy for the original strange cells to absorb, causing the system to subconsciously attack human cells at the critical moment of upgrading?" Shen Ge raised his hand and wiped the blood from his mouth and nose. In fact, except for the bleeding from all seven orifices, he did not feel any discomfort.

Of course, Shen Ge was also very clear that his idea was only the "best direction of development". If he thought of the worst, the system, as the ancestor, had grown to an almost "complete" point. Even if it turned the tables and managed to completely occupy this body, Shen Ge would have no way to stop him.

However, based on Shen Ge's experience, usually when a slightly lower-level monster appears in the body of a high-level monster, it is not easy for the lower-level one to completely occupy this body.

For example, in the fragment world, Dajing, who had a fifth-order fusion monster in his body, had a sixth-order weirdness, and finally successfully suppressed the opponent with the sixth-order weirdness.

Shen Ge thought that if the system had intended to seize this body, it would not have had to wait until now, because he had found a more suitable "symbiotic" form between it and it.

That's why Shen Ge thought positively, because this "upgrade" was very critical, otherwise the system would not have continuously drained the energy in his body for replenishment. When the evolution reached the critical point, Shen Ge consumed a lot of strange energy because of the battle, which caused his body to collapse.

"Student Xiaoqi, I have a bold idea!" Shen Ge suddenly said.

Xiao Qi had a bad feeling when he heard that, and said anxiously, "Master, I think we should be safer. I will attach a full-body red mist armor and take over the battle. You can take a good rest and eat the last two spirit apples to restore your weird energy."

"No, I don't want to continue fighting, but I want you to continue to supply me with the red mist energy through the red mist armor." Shen Ge said in a deep voice.

As soon as he finished speaking, Shen Ge had completed the attachment of the red mist armor.

His "transformation" immediately scared the surrounding anti-evil agents, who thought that Shen Ge was swallowed by a parasitic monster.

After hearing Shen Ge's reassuring explanation, everyone finally breathed a sigh of relief.

Emily looked at the complete Red Mist Armor and ignored the injury on her foot. She limped over and her eyes showed a fanatical expression: "I have heard that Captain Shen has a strange energy armor that surpasses nanotechnology. I didn't expect it to be so..."

Shen Ge was too lazy to pay attention to this fanatical researcher. In his eyes, Emily's every move was just a "performance" by the members of the weird organization.

Classmate Xiao Qi was still trying to persuade Shen Ge. With the tacit understanding between him and Shen Ge, he knew what the other party was planning as soon as Shen Ge said that.

"Master, do you really intend to use the red mist energy to 'feed' the system? If the other party really intends to occupy the body, there will be no regrets then!"

Shen Ge pondered and said, "I understand. But in the current environment, we will either be trapped here and killed by the fusion monsters, or recover our combat power and fight them. In comparison, the threat of the system is smaller. Don't forget that we have supplied the Red Mist with unlimited energy more than once, including after the Red Mist Armor was fused with the characteristic 'Endless'."

"If the system can complete its plan and replenish itself by continuously absorbing the red mist's strange energy, I should have died no less than three times!"

"In fact, I have been in a passive position since the system awakened in my body. Even if the other party wants to occupy this body, they have to wait until I squeeze out its surplus value!"

Faced with Shen Ge's insistence, Xiao Qi had no choice but to start controlling the red mist armor to form blood threads and inject them into Shen Ge's body, continuously delivering the red mist's strange energy.

After replenishing the "energy", Shen Ge finally stopped bleeding and the "collapse" of his body was also alleviated.

At this time, facing the round after round of bombardment of the surrounding strange energy artillery on the strange warriors, the huge strange heart in the center issued a deafening scream.

The faces of the people around exploded one after another, violent vibrations came from deep underground, the flesh and blood on the top of the mine began to collapse, and huge stone pillars and pieces of flesh fell like sharp swords.

Shen Ge grabbed Emily's wrist and leaped towards the nearest flesh and blood passage. Mark's roar echoed around: "The cave roof has collapsed! Retreat! Find shelter!"

It is almost impossible to destroy a strange heart of this level with only the strange weapons of Mark and others. Shen Ge prefers to believe that the other party is compressing and closing the space for "self-protection" to prevent these foreign "bugs" from continuing to gnaw on the heart.

The strange heart could not be destroyed in a short period of time, so everyone had to retreat first, and Shen Ge also wanted to make plans after his physical condition stabilized.

After everyone passed through the flesh and blood tunnel and entered another area of ​​the underground laboratory, the vibration gradually stopped and the entire underground world returned to peace again.

"Xiao Qi, what's the situation in the heart chamber?" Before leaving, Shen Ge asked Xiao Qi to leave a lot of blood spiders for monitoring.

Xiao Qi replied, "Master, it's consistent with our prediction. The space has been compressed. The heart chamber, which was originally several thousand square meters, has shrunk to three or four times the size of the heart, and several of the flesh and blood passages leading to the heart chamber have also been closed. In the flesh and blood pool, at least a thousand humanoid monsters have been resurrected."

Shen Ge sighed. He didn't expect that he would accidentally enter the heart chamber directly. As luck would have it, his body had problems and he was unable to destroy the strange heart in one fell swoop.

The other party is now on guard. Even if we find a way back, it may not be easy to destroy the strange heart.

"Shen, Captain Shen, come and take a look!" At this time, after escaping into this area, Mark, who led a few people to explore the surrounding area to ensure safety, shouted in front of the flesh wall in the distance. (End of this chapter)
