The Apocalypse Is Coming, but I'm Playing Plants Vs. Zombies

Single male protagonist ➕ single female protagonist ➕ system (Plants vs. Zombies fanfic), this is my debut work. If there is anything I don't like, I hope you can correct me and give it a try. I hope you will give me your advice and criticize. The eighteen-year-old Wei Lingtian was brutally killed by the Corpse King in the last apocalypse. His biggest regret before his death was that he failed to protect his childhood sweetheart Su Ling. With endless regret, he was reborn on March 15, the day before the apocalypse broke out. At this time, the Salvation Company's "evolution potion" had not yet been distributed, and the zombie virus had not yet swept the world. At the same time as he was reborn, the dark ring he picked up on his finger activated the Plants vs. Zombies system. Plant seeds such as sunflowers and pea shooters became his confidence in fighting zombies. In order to protect Su Ling, Wei Lingtian risked everything, mortgaged the old house left by his parents, borrowed loan sharks, frantically raised funds, and traveled to wholesale markets, supermarkets, and hardware markets to hoard food, medicine, weapons, and daily necessities. He found a mountainside farmhouse that was easy to defend but difficult to attack as a shelter. He spent a lot of money to renovate and strengthen it, refit the vehicle, and install water purification equipment, just to give Su Ling a safe harbor. After meeting Su Ling again, the two untied the knot of ten years, confirmed their feelings, and agreed to face the end of the world side by side. However, crises come one after another. The threat from the loan shark leader Dao Qiang, the zombie wave that breaks out in advance, and the conspiracy of the Corpse King hidden behind the scenes are all testing the young girl. Relying on the rebirth memory and plant system, Wei Lingtian vowed to break fate, protect Su Lingzhou, form an army of plants, and support each other's survival in a fallen world.
