Jiang Xue and Jiang Tian hurriedly passed through the northern section of the school, where most of the research labs were. They checked the rooms one by one but didn't find anything suspicious yet.
"Sister, we can't just keep on searching like this." Jiang Tian suggested with a frown, "Why don't we inform them and have the people in these labs come out by themselves?"
Jiang Tian had a baby face and looked like a newly graduated college student, but he was already a veteran police officer of several years.
He knew they were short on time for this assignment, and it was also inconvenient to send lots of officers into the school, so the police could only rely on the two of them to covertly investigate.
His older sister, Jiang Xue, joined the police force a year earlier than he did, so she had more experience. At this time, she shook her head. "No, we can't accidentally startle the target."
She knew more about the story behind this mission. "This incident isn't simple. Once the target gets away, there may never be a chance to catch him again."
Jiang Tian couldn't help being curious. "Sister, what exactly is the mission this time? The captain didn't even tell me…"
Jiang Xue frowned slightly, but since the mission was right in front of their eyes, there was nothing to hide now. She immediately asked, "Have you ever heard of the Full Moon Cult?"
"That evil cult?!" Jiang Tian immediately exclaimed. He knew all too clearly about the Full Moon Cult's fierce reputation.
Jiang Xue nodded darkly without another word. And once Jiang Tian learned that this mission was actually related to an evil cult with a fierce reputation, he immediately lost interest in asking more questions.
The two sped up their pace, but right then, a startling energy fluctuation originated from not far ahead.
...
In Tian Yuan's lab, 50 moon thralls were squeezed into a cramped space together, and a red mist was slowly released into that space.
Under the influence of the red fog, the moon thralls' gazes turned ferocious and cruel, and the vicious nature in their hearts was thoroughly aroused.
With a loud growl, the moon thralls started fighting each other.
The space for their activities was too narrow, so most of the moon thralls were crowded together. Rather than fighting, crazily tearing into each other was a more apt description.
They used their teeth, claws, and all the weapons in their disposal to hurt and kill their own kind.
Tian Yuan watched all this dispassionately, and when only half of the moon thralls remained, he waved indifferently. "Start pouring the Heroic Spirit origin fluid."
The Heroic Spirit origin fluid was the same as the rainbow-colored spring water inside the Heroic Spirit Temple used to heal injured Heroic Spirits.
This kind of fluid had a superb recovery effect on Heroic Spirits and was very expensive. It was usually diluted, yet Tian Yuan had used ultra-high concentration fluid right now.
The rainbow-colored sticky fluid began to permeate the small room and soon covered the ground in the enclosed space.
The fighting among the moon thralls turned even more desperate. As soon as they received a wound on their bodies, it would quickly close up from the effects of the healing fluid. Just like this, they ripped into each other endlessly.
Fresh blood continuously flowed down, mixing with the Heroic Spirit origin fluid on the ground to form a sticky mixture that reeked of blood.
...
"Sister, hurry up! It's just ahead!" Jiang Tian took the lead, practically flying through the experimental area, and soon came to a stop in front of Tian Yuan's lab.
He had already used the power of a Heroic Spirit to reach an amazing speed. However, Jiang Xue's Heroic Spirit wasn't a speed type, so she could only lag behind, gasping for breath as she tried to catch up.
But Jiang Xue didn't have time to complain now. She caught up to her younger brother while panting. "Hurry! Smash the door open!"
Jiang Tian nodded heavily. He mobilized all the power of the Heroic Spirit possessing him and gave the lab door a heavy kick.
Boom!
"Ahhh! It hurts…"
A loud impact echoed throughout the research building. Three seconds later, Jiang Tian cried in pain as he held his foot, but the door didn't budge.
Jiang Xue's face darkened. She pushed him aside and grunted angrily, "You're so useless. Watch how your sister does it!"
Jiang Xue's Heroic Spirit was also the possession type, but her realm was obviously higher. When she used her full power, the illusory form of a grizzly bear even appeared behind her.
A bear's roar seemed to travel through the air, and the young girl slammed her palm onto the door with all her power.
They heard an even more oppressive noise, but the door still refused to budge. Jiang Tian looked at it all in disbelief.
"This door really is strong," Jiang Xue said nonchalantly as she silently withdrew her hand, but Jiang Tian clearly saw that her right hand was trembling.
At that moment, two figures appeared in front of them—a young man in a gray suit and an old man with a long white beard.
The two police officers didn't know how they could appear out of thin air like that and immediately became alert. Jiang Xue frowned and asked, "You two are…"
However, the two newcomers ignored her. The old man continued explaining, "My Lord, this door is made through a secret technique and is connected to the entire laboratory. Destroying it through brute force will also destroy the lab."
"Oh, I see…" Jiang Tian exclaimed from the side but immediately shut his mouth upon an angry glare from his sister.
It's just that both police officers felt their hearts sink. It was fine if the door was simply strong; there would always be a way to break it open. But if it was connected to the lab…
Wouldn't destroying the whole lab give the people inside a chance to take advantage of the chaos to escape?
The young man's expression remained unchanged. He said indifferently, "Let's enter and take a look."
The two officers who heard him looked at him simultaneously with strange expressions.
'Did this person not hear that old man just say that the door can't be smashed open?'
But they saw the young man step sideways, walk past the door, and directly punch the wall right next to the door.
Boom!
A noise far louder than the previous sounds came, and the lab's outer wall was directly blown away, leaving a huge hole…
By the time the two police officers came back to their senses, the two newcomers' figures had already disappeared, and without thinking too much, the officers quickly got up and rushed into the lab.
What greeted them was the bloody scene taking place inside a small transparent room.
With a face full of excitement, the last surviving moon thrall was crazily sucking up the contents inside its kin's skull, eating even the brain and rapidly swallowing the food.
After swallowing all of its kind, the skin of this moon thrall gradually reddened, and its body also showed a strange bloody color.
Jiang Tian, who had never seen such bloodshed before, almost threw up.
Jiang Xue's face twitched slightly, but she still choked back her disgust and shouted, "Tian Yuan! Stop the experiment immediately, or else we won't be polite!"
Tian Yuan, who was standing in the middle of the lab, smiled faintly and shook his head. "Too late…"
Bang!
The transparent glass was directly smashed by the blood-colored moon thrall, and it jumped out and immediately pounced on the surrounding staff.
One of them couldn't dodge in time. The moon thrall bit his neck, and the researcher collapsed weakly.
"Professor Tian, what… what the hell is going on?" A researcher stood behind Tian Yuan, gaping at this scene, which was completely different from the results they expected.
"Moon thralls are a type of extremely pure Heroic Spirit. Their individual differences are so small that they can even devour each other for genetic evolution."
Tian Yuan was like a victorious general, calmly explaining his achievement, "The devouring order I gave them isn't self-regeneration like you all believe, but instead, it's…"
Tian Yuan dragged out his tone, his hollow eyes falling onto that researcher without a trace of emotion, "Infection."
