Is there no hidden content after the Office..?

Is it time to delete it.. I went up after restarting the traditional market once. In research enhancement, I only upgraded production tools and didn't produce handmade fries from the traditional market onwards. With the points obtained from restarting, I upgraded the remaining production tools, produced with diamonds, and used combat boosters. I only leveled up mercenaries to level 100, and for upgrades, I first raised production and then the rest of the mercenaries. I did it quickly, but it seems there's no more hidden content.
