Doomsday：I have the Red Alert Army

The uniqueness of the world originated from its capacity to shift from tranquility to utter chaos in an instant without any preceding indications.
Han Feng was a fresh graduate who had just clinched an internship at a nondescript company. Not born into wealth, nor burdened by poverty, his life had been comfortably ordinary. Little did he anticipate that on what seemed to be another routine day, his gaze would be met by a nightmarish tableau, an assemblage of horror reminiscent of a zombie apocalypse.
The shock etched itself into Han Feng's psyche, nearly pushing him to the brink of despair. Amidst his turmoil, a mechanical voice materialized within his mind, posing an unexpected question: did he wish to construct a power station?
Initially dismissing it as the product of his frayed nerves, Han Feng recognized the voice from a previous night, when he had half-dozed off while playing the Red Alert game. His skepticism dissolved as he comprehended that this was no dream.The game had transformed into a tangible system, a conduit allowing him to transmute virtual creations into reality itself.
From summoning soldiers to calling forth formidable warriors, Han Feng's world expanded exponentially.
Armed with this system, will Han Feng only save himself or save the world from the zombie apocalypse?
