2003 Book(s) Related to Desiring My Professor

When the apocalypse came, I became one of the military's failed experiments—defective, useless, a waste of space who only knew how to fix machines.
My so-called brother Kane used the camp leader access I got for him to trade away the comms gear I nearly died to secure for a bottle of whiskey. He drained my bone marrow dry to keep me in the dark, then dumped me out in the wasteland to die.
After that, he pinned every bit of luxury and waste on me—
while my little sister didn't even have the medicine she needed to stay alive.
That night, dragging my crippled body behind me, I reached into the substation.
Kane, do you remember what kind of genes were in those five hundred milliliters of bone marrow?

When the apocalyptic red rain fell, my brother and I both awakened spatial abilities.

He awakened a space as vast as a mansion and was hailed by the entire family as their savior.

While I only awakened a "suitcase" and was ruthlessly drained of all my assets by my parents to support my brother, then kicked out of the house.

They mocked me cruelly: "We don't keep deadweights. Go wait for death in the 70-degree furnace outside!"

What they didn't know was that my brother's space had no preservation function—his stockpile of premium ingredients would soon rot into a pile of maggot-infested meat.

But my suitcase had upgrade attributes!

While they fought each other over a sip of putrid green water in the 200-degree hellscape,

I sat in the "Eden" I had created, watching herds of cattle and sheep, drinking ice-cold fresh milk.

Betrayed to death by my own brother, I was reborn before the apocalypse descended.
He rushed to seize the god-tier [Copy] talent first, leaving the trash [Purification] talent for me.
He thought that with this talent, he'd have no worries and reign supreme in the apocalypse.
Meanwhile, I quietly closed the last door of my fortress.
He didn't know that his prized copying ability had a fatal flaw.
