Anime Crossover: The Small Workshop System's Aggressive Feeding

When thousands of fantasy worlds merge, how can an ordinary person survive in this chaotic world of gods and demons?
Zhou Ye, transported to a crossover anime world by a truck, awakens his past life memories and obtains the belated but welcome [Small Workshop System]. Each completed dungeon quest grants him materials from various realms, allowing him to become stronger! The biological DNA editor from Resident Evil and Demon Slayer? The method for creating the Primarch of Warhammer 40K? Genetic technology from Super God Academy? If you can imagine it, the system dares to give it to you! It's just that there's a tiny bit of difficulty involved.
Zhou Ye doesn't want to let go of his childhood friend, Himejima Akeno, but powerful enemies surround them, and the dungeon worlds are fraught with danger! To protect his loved ones and to avoid being branded a "green grassland" (a symbol of betrayal), Zhou Ye must frantically plunder resources in various worlds to become stronger and survive, thus avoiding the "green grassland" label.
