We live in a technologically advanced society every day. Sometimes we may feel a little unhappy, but it will pass quickly. But have you ever thought about what you would do if one day you woke up and the whole world had changed? What would you do if your closest family and friends turned into man-eating monsters and pounced on you unconsciously. Despair, fear, and helplessness weigh on everyone's heart. In this era, you not only have to guard against zombies, animals, and plants, but you also have to guard against human hearts. Tell me how do you survive? I thought I would not be able to live anymore if I lost the only warmth in my life, but fortunately God showed mercy and allowed me to return to the past by chance. Then this time I will make those who have hurt you pay the price, and I will spend my whole life standing by your side.
