I Have a Space-Time Warehouse

Emm, it's annoying enough to give 20 gold for the ID card in the front, but in the back, everything is the same as the adoptive father, 300 gold rent for three years, and you can buy two top-notch fairy treasures in 30 years. It's nonsense, the fairy water is used like waste, bathe, give away, but these are all stolen, and give two to the enemy in the back A top-level fairy treasure makes porridge, which makes people laugh to death, but the opponent does not improve, which is even more amusing. The system also tells the protagonist that he has the blood of a radiated cockroach haha By the way, the top fairy treasure successfully helped others break through the first level, completing a small breakthrough from the peak of physical training to the first level of qi training. I am afraid this is adapted from the author's dream.
