Doomsday Recharge: A Safehouse from the Start

In his previous life, Lin Jin was betrayed by his brother and died a miserable death. Reborn 23 minutes before the apocalypse, he gains the one and only concept-level talent, “Recharge Anything.” While others kill monsters for gear, he kills them for cash. While others build bases with manpower, he recharges his treasury and upgrades it straight into an apocalyptic safehouse. Everyone who bullied, deceived, or harmed him in his previous life becomes an experience pack this time around.

Humanity thought it was facing an apocalypse. Only later did they learn it was an exam to determine whether their civilization deserved to survive.
