Everyone urged him to grieve, to give up.
They spoke of how precious the antibodies were, the hope of all humanity.
He watched his own daughter slowly mutate, and in the very second she fully turned into a zombie, she was still sweetly calling out to her Daddy.
He just watched her fair, tender little hands gradually turn bluish-purple.
And his daughter was even still acting spoiled with him.
Afterward, even he himself thought this way. He felt he had done nothing wrong. His daughter had at least died with purpose; he was thinking of the greater good of all humanity.
But as time passed, he finally understood how outrageously wrong he had been.
Later, after continuous refinement, the antibodies had become very mature.
He sought out his superiors more than once, asking why, now that the antibodies were so mature, they still weren't being deployed.
But everyone's answer to him was to wait.
Yet, in this day after day of waiting, he became utterly disillusioned.
During these years of living like a walking dead, the only thing he cared about was that he had secretly hidden his daughter from everyone back then.
He had even taken her to the lighthouse, and no one knew.
Gradually, he discovered that, apart from the very first batch of original antibodies, they seemed to have stopped this research. And the matter of pushing this antibody to the entire world, as initially agreed, had never materialized.
He finally despaired.
But during an experiment, he accidentally overheard someone discussing the original antibodies. He was hiding behind the door at the time; no one noticed him.
It was at that moment that he truly saw through human nature and understood how foolish it was to have abandoned his daughter back then.
It turned out that a certain high-ranking official had decided to suppress the matter.
The reason was simple: they didn't want to widely distribute this vaccine.
Although disasters were constant, as long as there were no zombie disturbances, life on the surface was not entirely impossible.
Once all the zombies in the world disappeared, the lighthouse would lose its reason for existence.
Then, facing the exorbitant prices within the lighthouse, returning to the surface wouldn't be an unacceptable prospect.
What they needed was absolute loyalty.
A reason for all the people to remain here, even if driven out.
And the lighthouse's greatest allure compared to the surface was the absence of zombies.
But once this sole advantage vanished, the lighthouse would face the consequence of widespread unrest.
When the doctor heard the entire process from beginning to end, he only felt it was absurd.
For such a reason, they disregarded all the people still suffering and enduring hardship due to zombies.
And it had forced him to give up his own daughter's life.
On that day, a seed called hatred quietly took root in his heart.
So, he subtly replaced all the original samples and destroyed them.
He knew the lighthouse had long since abandoned the research of antibodies. Although they were now under the guise of antibody research, they were actually using the zombie virus to create human weapons.
It was a form of human modification experiment that utilized the characteristics of the zombie virus to make the human body lose the sensation of pain and accelerate its functions.
The doctor also played a role in fueling this.
He successfully became the lead in this experiment, and he had long had his eye on that man who was single-handedly raising his daughter.
He knew that man's daughter suffered from a rare disease and might only be cured with the blood purification system in the medical pod.
But having gone through it once, he knew too well what kind of people they were.
How could they possibly lend the medical pod for free?
He watched as that man, just like himself back then, begged everyone, seeking a chance for his daughter's treatment.
He watched the man despair time and time again, only to go and beg again and again.
But no one knew better than the doctor himself that it was all useless.
Those people would never bestow charity upon him.
So, he proposed that the current experiment had reached a critical stage and needed to proceed with human trials.
He then informed Yueyue's father of this news.
And he offered a condition: those who participated in this human experiment would be allowed to use the medical pod for free.
Perhaps, in his heart, he thought that since he couldn't save his own child back then, he was giving this opportunity to the man.
This was why so many subsequent events unfolded.
It wasn't until the man escaped from the laboratory that he discovered the outside world had descended into chaos.
He then realized why the doctor had wanted him to bring out those viruses.
He had initially thought the doctor simply wanted to resurrect his daughter, but he never expected that the doctor's true intention wasn't to resurrect his daughter at all, but to destroy the entire lighthouse.
However, whether it was the last vestige of kindness in his heart, or a final glimmer of hope left for the world, he ultimately injected the last original antibody into Yueyue.
At that time, Yueyue's health had completely recovered after the treatment.
And the man, through numerous experiments, had successfully endured. Not only did he maintain his consciousness, but he was also the only one among that batch of experimental subjects to remain lucid.
The man possessed almost all the initial hypotheses of the experiment. But at this very moment, the entire laboratory was overrun by zombies.
And the man also escaped from the laboratory. His first priority was to find his daughter, and then his mother.
Although the people in the laboratory said he was the most perfect test subject, he knew himself that while his body had been enhanced, his mind often became hazy.
He frequently needed simple commands to briefly regain his senses.
He knew what this meant, so he entrusted Yueyue to his mother, and he himself wandered outside with an already discarded vaccine.
He still couldn't comprehend the doctor's actions.
If he hadn't known what had happened to the doctor, he might have resented him like most people, blaming him.
Even hating him, because it was he who caused all the suffering today.
Not only that, but the doctor had indirectly helped them.
Not only did he heal Yueyue, but he also gave the only antibody to Yueyue.
He couldn't muster any real hatred towards that man.
But it was precisely this sentiment that made him feel like an outsider now.
He wandered for half a day, unable to grasp his own thoughts.
Did he want to find the doctor, or did he want to find the rescue team and reveal the matter of the antibody?
It wasn't until he encountered Xu An on the way.
At that time, he realized that he was no longer attacked by zombies.
But to avoid drawing attention, when humans appeared, he would deliberately provoke zombies to attack them.
Most people, seeing him being chased by zombies and with wounds on his body, would instinctively avoid him.
But Xu An did not.
That girl not only helped him but also promised to take care of Yueyue.
