I Transmigrated to Warhammer 40K, and I’m the Strongest

[Zhen Dan Elements] [Humanity's Revival] [Primarch] Hello, everyone. My name is Li Er. I woke up one day and seemed to have transmigrated into Warhammer. It also seems my soul was transported here, and I can't remember anything. All I recall is that when I transmigrated, I was dazed and confused as I got swept away by a warp storm to some unknown place. As a result, my soul was dumped into the body of a Guardsman. I was still bewildered, with no idea what was going on, when a Greater Daemon of Khorne came walking toward me. In a panic, I knocked him down with one punch. (The author is a casual Warhammer fan.
