The Person Was in a Coffin and Fed on Blood by the Reborn Empress.

[Rebirth of the Empress] + [Decisive Killing] + [Nervous Protagonist] + [Global Mutation] + [Survival in the End of the World] I, Su Chen, traveled through time and space into the body of a zombie who was transforming into a corpse. In this dark coffin, I lived in confusion for a month. Just when I thought I had to wait until the corpse transformation was over before I could go out, the grave was actually dug up! A woman sat on me, feeding me blood, and talking about feeding on blood and forming an alliance between different bodies. Although I don't know what I'm doing, the blood tastes delicious. Also, why do I transform into a corpse so fast? ………… I, Ji Ruxue, was the empress of the human race in my previous life, and fell because I was defeated by all races. After rebirth, I found that I was back to the day before the global mutation, but my talent was awakened in advance - alliance (attribute superposition between allies!) In my last life, after the mutation, I went through a lot of hardships to find a suitable ally, but I wasted two years because of it. In this life, I decided not to waste these two years. So I came to the back mountain and dug a grave named Su Chen. This was a zombie that had not yet successfully transformed into a zombie. I am ready to form an alliance with it and feed on blood to help him transform into a corpse in advance.
