Invincible Astartes

Open your eyes and it's hell. Tarkus, an ordinary working overtime worker, woke up to find that he had become a newly transformed Astartes recruit in the Warhammer 40K universe. The second heart is still bleeding, the black carapace has not yet grown, and the power armor is not even warm—— The Chaos Fleet is coming. Bite! Plug-in system activation. Automatic blood recovery: Recover 5% of overall function every second. There is no novice tutorial, no retreat route, and no protagonist aura. Tarkus clenched his bolter and followed 99 equally ignorant recruits, who were thrown into the bloodiest meat grinder of the Great Crusade. He watched his comrades being torn apart by psykers, watching veterans being possessed by demons, and watching hope being swallowed up by chaos bit by bit. There is only one belief that supports his survival—— As long as he's still standing, he'll be beaten to death. (This book is hard-core, slow-burning, and not brainless. The system is only an auxiliary. Real growth is bought with blood and tears.)
