A week later, Captain Chen handed me the antibody vaccine.

He also gave me a handgun with only one bullet inside.

He didn't explain the purpose of the gun, but I understood.

If the antibody didn't work, the zombies would become mindless creatures, and at that time, Gu Xiao should find release.

I returned to the bunker and opened the storage room.

A putrid smell mixed with the stench of blood instantly hit me.

A zombie can survive for a month without food, but it will lose its vitality.

For the past two years, I've been afraid of Gu Xiao's body failing, so I've been drawing blood to nourish his body.

At first, he refused, not even taking a sip despite his eyes turning red from holding back tears.

Later, perhaps unable to bear the hunger, he gradually accepted my blood.

Gu Xiao sat untidy in the corner and raised his head in my direction when he heard the door open.

With blood nourishing his body, he was no longer just skin and bones.

I cautiously approached and raised the syringe.

As the liquid entered his body, Gu Xiao reacted almost instantly.

Perhaps due to pain or unfamiliarity, he raised his palm to swat away the needle but hesitated, afraid of hurting me, and gently put it back down.

On the first day, Gu Xiao showed no reaction.

On the second day, Gu Xiao showed no reaction.

On the third night, I opened the door to the storage room, and Gu Xiao's eyes were still clouded.

"Gu Xiao, I beg you, this is the last way to save you..."

I approached, wanting to hug him.

But Gu Xiao disregarded everything and tried to bite my neck.

At that moment, I lost all hope.
