Infinity: Kill your way through the movie world.

He swiftly brought down the knife.

The blade sliced ​​through the juvenile's neck, completely separating the head from the torso.

The two parts stopped wriggling the moment they separated, and the yellow color quickly faded, turning into ordinary, dark gray necrotic tissue.

“It must be completely separated,” Wu Heng emphasized. “Sever all connections; if even a single thread remains, it can regenerate.”

Dean looked at the beakers and debris, and suddenly asked, "When did you start researching this?"

“It all started when you brought back the first on-site sample,” Wu Heng said. “Sam dug up a small piece of contaminated soil from the reservoir, and the lab analyzed it overnight, conducting seventeen sets of control experiments. These are the results.”

He turned around, pulled a report from the filing cabinet, and threw it on the table.

The report cover is printed with 'Biological Characteristics of Leviathan and Countermeasures', below which are densely packed data charts and experimental records.

"So you've called us here now to clean up those escaped larvae?"

“Yes.” Wu Heng nodded. “According to energy tracking, most of the larvae are still concentrated within a 20-kilometer radius around the reservoir. They need time to adapt, find hosts, and establish infection networks. Now is the best window of opportunity to clear them out. It will be difficult once they spread.”

Dean picked up the report and quickly flipped through it.

It contains detailed records of the infection process, changes in host behavior, and effectiveness assessments of various attack methods.

"I'll stay here to monitor the overall situation. You, Sam, and Bobby will lead the guild's witcher team to carry out as much cleanup as possible."

Wu Heng turned to look at the monitoring wall at the other end of the laboratory.

The wall displays a dozen screens showing real-time footage from different locations: reservoirs, surrounding towns, major highways, and... a schematic diagram of the water supply system in Grantspass.

“Leviathan won’t just stay in the reservoir.” He pointed to the water supply system. “Water is its medium. It will spread along the water supply pipes. The water source for Grantspass comes from the same water system. I have detected abnormal water quality at three water supply nodes, but the specific scope of infection, the number of infected people, and the mastermind behind it... require on-site investigation.”

He paused.

“That requires more specialized witchers, like you.”

Dean and Sam exchanged a glance.

“One last question,” Dean asked, addressing the topic he was most concerned about. “Regarding Castio’s soul, you said he disappeared. Is it possible that he still exists or lives in some form?”

Wu Heng remained silent for a few seconds.

The only sound in the laboratory was the low hum of the instruments running.

“The soul doesn’t just disappear into thin air.” Wu Heng thought for a moment. “It will only transfer, transfer to another container, or… another place. The energy trajectory I detected shows that there was a high-intensity spatial fluctuation 0.3 seconds before the Castio sac disintegrated. The fluctuation characteristics are not like Leviathan’s methods, but closer to… Heaven’s technology, but not exactly the same.”

He pulled up another set of data.

The screen displayed a complex energy waveform, with three interwoven curves: red representing Leviathan energy, white representing Castio's angelic essence, and a faint, almost invisible blue curve that suddenly appeared at the last moment, rapidly peaking before returning to zero.

“This blue line,” Wu Heng pointed to the screen, “appeared for a very short time, but its strength was enough to tear apart a temporary spatial passage. If Castio’s soul was really taken away, this is the vehicle.”

Dean stared at the blue line: "Can it be tracked?"

“We’ve tried.” Wu Heng shook his head. “The signal attenuates too quickly, or it might be blocked by some kind of shielding field. But one thing is certain: the one who takes away the soul is not Leviathan. Leviathan only devours, it doesn’t transfer.”

Sam took a deep breath: "So there's still hope." "Theoretically, yes." Wu Heng turned off the screen, "But let's deal with the immediate threat first. Castio's matter can wait, but Leviathan won't."

"Any leads in Grantzpass?" Dean asked again.

Wu Heng retrieved a file from the console.

"The city of Grantspass has reported 24 cases of 'sudden fainting' where patients suddenly collapsed at work or in their daily lives. After being taken to the hospital, they were found to be normal, but upon waking up, they exhibited subtle changes in behavior—becoming quieter, more cooperative, and becoming distant from family and friends. The hospital attributed this to excessive stress."

He pulled up another photo, which showed a man in his fifties with gray hair, wearing an expensive custom-made suit, and a professional smile on his face.

The photo was captioned with the other person's name: Dick Roman, CEO of New Era Biotechnology, who acquired the largest food processing plant and two supermarket chains in Grantspass three years ago.

"He fainted half an hour ago,"

Sam looked closely at the photo: "You think he was also parasitized by Leviathan?"

Wu Heng nodded: "His company controls 60 percent of the food supply and 40 percent of the retail channels in Grantspass. If you want to add something to the food... there is no one more suitable than him."

Dean put the photo in his pocket: "Address?"

“New Era’s headquarters are in the city center, but he spends most of his time at Sulford Hospital in the suburbs, a private hospital that he donated to rebuild five years ago. It’s nominally a charity, but in reality, medical records are not made public.”

Wu Heng glanced at the clock on the wall.

“It’s 2 p.m. You’d better head to the reservoir immediately and meet up with the Witcher team that’s already there. At 8 p.m. I’ll cut off the disinfection systems at the three main water supply points in Grantspass. That will force the Leviathan larvae into an active state, making it easier for you to track them, but it will also temporarily increase the risk of infection, so you need to act fast.”

Dean slung his backpack over his shoulder, and Sam was also fully equipped.

As the two reached the door, Dean turned back: "What if... what if we find a clue to Castio's soul?"

Wu Heng was organizing experimental data and didn't even look up.

“Then there is still hope for survival,” he said. “But remember to stop Leviathan from spreading first. If it completes its infection network, more than just Castio will die.”

The door closes.

Wu Heng was the only one left in the laboratory.

He walked to the monitoring wall, looked at the satellite image of Grantspass on the screen, and felt the surging power within him being continuously integrated.

He knew, of course, where Castio's soul had gone, but he couldn't say it directly.

There are 5 hours and 53 minutes left until 8 p.m.

Grantspass, East District, old apartment building.

Bobby parked his car two blocks away and walked over. He was wearing a faded work jacket and carrying a tool bag, looking like an ordinary plumber. In reality, the tool bag contained a can of borax spray and a special machete.

The apartment building has six floors, with mottled exterior walls and rusty fire escape stairs.

Bobby entered through the back door. The stairwell was filled with the smell of mildew and cheap disinfectant. He went up to the third floor and walked along the corridor to room 305 at the very back.

The sign on the door read 'Jansen'. (End of Chapter)
