Several days had passed, and during that time Wen Wen had not gone out to hunt monsters; instead, he'd been improving his knowledge about superpowered individuals through various channels.
While he was somewhat confident about capturing monsters with preparation, his limited understanding of the world of superpower users prevented him from adequately responding to sudden situations, as had been clearly demonstrated during his previous encounter with the Feathered Serpent.
Furthermore, as a detective, Wen Wen had strong counter-surveillance abilities and had sensed that someone had been watching him over the last few days.
One would naturally think that, as an organization overseeing ability users, the Hunters Association wouldn't just settle for signing a few papers and handing over some information before leaving him alone.
That was precisely why Wen Wen had refrained from taking any action these past few days, even avoiding entry into the Catastrophe Containment Facility. He certainly didn't want the Association to learn of his ownership of the facility.
Despite the absence of surveillance cameras in the hotel, he knew that the Hunters Association could be monitoring him using some strange methods.
"Sigh... I've nearly finished catching up on the knowledge I needed, and the person who was watching me seems to have backed off. If I stay here any longer, I'll start to mold."
Wen Wen let out a breath and tossed the cup noodle container into the trash bin, then began walking around the hotel. The observers he had previously spotted had all disappeared.
He then packed up all his belongings and moved to another hotel, carefully observing all the while, which confirmed that no one was watching him anymore.
"It seems the surveillance on me truly has ended."
Wen Wen finally relaxed. Being under surveillance was uncomfortable, but the past few days of observation hadn't been without gains; at least now he would not have to worry too much about the Hunters Association.
Afterward, Wen Wen started to swing his fists and feet around his current location. His movements were extensive, and his speed was rapid, creating whooshing sounds with his motion, yet his feet landed incredibly lightly.
This kind of exercise was ineffective at enhancing his combat strength but helped him get familiar with the vampire constitution.
Moreover, Wen Wen had a hunch that as he used his Vampire Constitution over time, his body's strength was also slowly increasing.
It was foreseeable that, with the development of the abilities of the Catastrophe Containment Facility, even without relying on these gloves, he would become stronger and stronger.
After some activity, Wen Wen stopped and furrowed his brows.
"My movements have slowed down... What could be the reason?"
During these recent days of gathering information and improving himself, he hadn't noticed any changes to his body. Upon recognizing that his movements had become sluggish, he immediately became concerned.
At this stage, the vampire's physical qualities were his livelihood, so he paid extreme attention to them.
"These past few days I haven't done anything; the problem shouldn't be with me. Moreover, I shouldn't need to drink blood..."
After pondering for a while, Wen Wen walked into the bathroom, closed the door firmly behind him, and entered the Catastrophe Containment Facility, going straight to the cell of Calamity-0001.
If he himself wasn't the issue, then the problem could only lie inside the Catastrophe Containment Facility, specifically with the confined female vampire.
When Wen Wen came in, the female vampire was slumped listlessly in the corner, while Little Ghost Qin Shuang was making faces at her, their statuses having seemingly switched.
Upon seeing Wen Wen arrive, the female vampire's eyes immediately turned blood-red, and her figure appeared at the edge of the cell in a flash, extending her hand trying to grab Wen Wen.
However, Wen Wen was at least a meter away from the bars, too far for her to reach him even if she stretched out her arms.
And the cell itself, she was even less able to shake.
The female vampire must have known this, yet she persistently stretched out her hands towards Wen Wen.
Wen Wen furrowed his brows; the female monster's condition seemed somewhat off. She had become much weaker compared to the beginning, and she was also not as rational as she had been at first.
"Could it be... she's hungry?"
He pricked his fingertip, squeezing out a drop of blood, waving it in front of the female vampire who followed his finger with her head, turning this way and that, like a begging puppy.
"Alright, it seems she really is hungry. Doesn't the Catastrophe Containment Facility feed its captives…"
Glancing at Ghostly Qin Shuang beside him, who was making faces with great energy, Wen Wen scratched his head, realizing that his strength was determined by the strength of the monsters in the cell.
The stronger the female vampire was, the stronger he became, so he couldn't let the female vampire continue to weaken like this.
Ghostly Qin Shuang didn't exhibit any abnormalities, which indicated that ghosts, unlike vampires, do not need to replenish energy, i.e., feed on blood periodically.
In fact, it was quite resilient for the female vampire to have held on until now before starting to weaken. She had been tortured quite a bit after Wen Wen had captured her, and had also shed a lot of blood, falling into a state of complete exhaustion.
She hadn't had the chance to feed for days, further diminishing her strength, which is why she was now in a state of extreme hunger.
"I didn't expect that I would not only have to capture monsters but also act as a keeper..."
As a relatively common monster, Wen Wen could also find information about vampires.
Low-Level Vampires, if they haven't fed for a long period of time, can fall into an utterly irrational state until they absorb enough blood to recover their rationality.
If they can't replenish blood in time, then the various bodily functions of the vampire will rapidly shut down, entering a state of slumber, awakening only when the conditions are right.
So if Wen Wen doesn't allow her to replenish blood, then the female vampire will fall into a deep sleep, and this ability would essentially be wasted.
Having left the Catastrophe Containment Facility, Wen Wen checked the sky, it was the depths of night, with only a scattering of stars and the moon brightly shining – the perfect time to do something clandestine.
So, he put on a black windbreaker, and after some thought, also hung the badge of the catastrophe containment officer around his neck, then jumped out of the window with sneaky movements, like a thief.
Well, he was indeed going to steal something.
Wen Wen's target was a nearby hospital, Renji Community Hospital, which had its own blood bank – and Wen Wen planned to steal some blood from there to take back.
For Wen Wen, with his Vampire Constitution, stealing some blood should be quite simple.
He only wanted to satisfy the hunger of that female vampire; whether the blood was fresh or tasted good was not his concern.
Even if he wanted to capture a thoroughly despicable person to serve as live food for the female vampire, he wouldn't be able to bring an ordinary person into the Catastrophe Containment Facility.
Standing in the shadows outside the hospital, Wen Wen felt a headache coming on.
There were more people in the hospital than he had expected, not as deserted as he had imagined, even in the middle of the night, with many people seeking treatment for their diseases—which, of course, did not wait for a convenient time of day to strike.
To move conveniently, Wen Wen wore a black windbreaker, but now, this outfit was not suitable to enter the hospital.
Entering wasn't really an issue, it just made him a bit too noticeable…
He walked around the hospital and discovered that half of the rooms in the western annex of the main hospital building were pitch dark. Wen Wen's face lit up with joy; he could enter the hospital from here.
