(Post-apocalyptic rebirth + storage space + hoarding supplies + incredibly powerful robot romance + lie flat + ruthless and decisive)
Lu Yang, who was stabbed to death by a green tea girl, has been reborn. His rebirth came with a huge bonus: not only did he retain the mutated physique ability he gained in his previous life, which made him immortal, but he also gained a storage space?
But I don't want this ability! Having it means I can't gain any other physique abilities.
Luckily, luckily, the heavens haven't treated him too badly. His rebirth also came with a beautiful robot with an astounding 99.999% level of realism and incredible strength (personally tested by the protagonist).
From then on, Lu Yang followed the girl around, coasting through life behind her.
