Hearing this question, Li Sen clearly remembered what had happened.

Six months ago, their company obtained an extremely rare virus discovered deep within the Antarctic ice layers.

This virus was extraordinary. It could update and iterate itself at incredible speed while maintaining its traits unchanged. It was almost a perfect match for humanity’s pursuit of longevity, and could also be applied to organ repair, human health maintenance, and a series of other great medical endeavors beneficial to human life.

This was the lifelong dream of every biomedical researcher.

The virus, named the T-Virus, seemed to fulfill every requirement of perfection.

No one could find fault with it.

At the request of the company executives, they quickly formed a project team, activated a Level 4 biosafety laboratory, and began a series of cultivation, analysis, observation, and preservation of this unique viral strain.

Everything was proceeding according to plan, and the experiments advanced in an orderly fashion.

Every researcher who had read the records and data marveled at the perfection of the T-Virus. It divided at a rate 1,000 times faster than ordinary cells, yet each generation almost perfectly preserved the traits of the original.

Only under extremely low temperatures would the T-Virus remain dormant and enter a resting state.

The group leader in charge of this project went mad with excitement.

They conducted experiments obsessively, day and night.

Soon, with incredible efficiency, they completed the first stage of animal trials and began actively recruiting volunteers for the second stage.

At first, the results of the human trials were very successful.

A child with severe burns regrew flawless, delicate skin indistinguishable from normal tissue.

A patient who had lost part of their arm in a car accident grew a new forearm and hand, perfectly fused at the break, even symmetrical with the other arm—as if shaped by the hand of God.

Patients in need of organs, after their cells fused with the T-Virus, grew entirely new organs and recovered their health.

Even elderly individuals at the brink of death wanted their decaying bodies restored to youth, with vigor, beauty, and strength—and it worked.

But with these successes, Li Sen and other scientists began to believe this was beyond their control.

Think about it: this virus seemed able to read thoughts, desires. No matter how outrageous the wish for bodily repair, it could make it happen. It was terrifying, almost demonic.

Yet some scientists saw it as a miracle.

They believed God had created this beautiful lifeform to grant humanity eternal life.

They likened themselves to Lilith stealing the apple from Eden, or Prometheus bringing fire to mankind. Since the Creator left behind such a perfect organism, it was their duty to spread this wisdom and fire, and to pursue humanity’s path to immortality.

Thus, with the full support of the project leader and tacit approval of the executives, recruitment for Phase Two clinical trials continued.

They secured a second, third, and even fourth batch of volunteers, requiring them to sign expensive confidentiality agreements and forbidding them from leaving Snowe City for a year to undergo follow-up monitoring.

But even with secrecy, word leaked. A flood of the wealthy rushed forward like moths to a flame.

The sick sought healing.

The disabled craved perfection.

The aging longed for rebirth.

But then—mutation occurred.

The first batch of humans treated with the T-Virus began dying one after another.

The company immediately dispatched teams to handle the bodies and compensate families, secretly hauling the corpses back for autopsies.

The results were horrifying—the virus had mutated.

Perhaps it was incompatible with human genes, or perhaps it had a sinister intelligence. After disguising its stability, once inside the human body—the perfect incubator—it began to grow uncontrollably.

Humans were simply too fragile to withstand such rapid, high-iteration cell reproduction. Their bodies collapsed.

And after death, they were taken over by a bloodthirsty will, transforming into frenzied, vampiric monsters, violently spreading infection to reproduce.

This virus spared no one. Every volunteer injected with it met the same fate.

A number of laboratory staff were killed.

And the company’s headache was not only the monsters slamming against glass windows—it was the knowledge that the first batch had only seven volunteers.

The second batch included over a hundred, among them the wealthy and government elites. If they began to transform, everything would spiral out of control.

The executives immediately moved to contain the second batch, reporting to the government in secret and requesting covert aid to bury the scandal.

The government compromised.

But the outbreak escalated faster than expected.

While the second batch was being rounded up, the third and fourth began mutating. The company lacked manpower and could no longer suppress the truth.

Hospitals across Snowe City filled with patients displaying rabies-like symptoms.

The citizens panicked. Infected people spilled into the streets, spreading the virus. The authorities cut off all internet access between the city and the outside world.

The public could not send news out, nor could the outside world receive it. An invisible hand tried to smother the scandal.

Now the situation was completely out of control. The authorities hypocritically wanted the original research to develop a vaccine, while also planning to drop a nuclear bomb to erase the incident.

This was everything Li Sen knew.

As a researcher, he resisted as best he could, but to no avail. He could only keep updating records and preparing countermeasures.

Now, in his hands, he still had the most complete research data and experiment logs, the original T-Virus strain, and the precious prototype inhibitory vaccine.

Although Li Sen despised the hypocrisy of high officials, he had to admit—they were the only way he could continue vaccine development and find a solution.

Li Sen’s account was thorough, and Su You understood everything.

She also realized that in her previous life, the outbreak may have gone unnoticed because Nation A’s leadership suppressed it.

Later, when natural disasters struck, news slowed, and everyone struggled to survive. Who would care about a small city vanishing across the ocean?

After all, even Sakura Nation had slipped into the depths of the Mariana Trench—countless small cities had disappeared without a trace.
