My Dantian's Flame Devoured the System

Story blurb: Did I really get sent back to the plane I was in before I transmigrated, just because I was going through a tribulation? No worries. I've returned with a whole set of skills unlocked. Looks like I'm about to reach the peak of my life. I originally planned to open a shop, earn a little money, and enjoy a leisurely life. I never expected to spend my days running from a bunch of plants and animals. Plant A: Master Alchemist, could you give me a Nourishing Essence Pill? I'll bloom for you. (*/ω\*) Plant B: M-me! I want to trade my fruit for an elixir. It took so much effort to grow it. Animal C: Give me an elixir, and I'll let you pet my fur. (lying flat) Animal D: Master Alchemist, this is an egg I managed to lay after a hundred years. I've pinned all my hopes on it... Xixi: Speak plainly. Animal D: (closes eyes and yells) I want to trade for an elixir! Xixi: ...Can't you trade me something normal? Danhuo: Wait, why didn't you mention me in the blurb? QAQ --This lovely cover was provided by the adorable and charming Sister Breeze-- My new story, "Interstellar All-Around Pharmacist," is now available. Visit my author page to check it out. Pharmacist Yan Duo transmigrates to the interstellar era, where she becomes a cannon-fodder character on an abandoned planet and inherits a run-down farm. The place is not only overrun with mutated plants and animals, but also filled with radiation. People can only defend themselves against contamination by using improved medicines. Looking at the lively mutated plants and animals, Yan Duo is in an especially good mood. Her specialty is a perfect fit, and she's even got free labor thrown in. Before long, a mysterious little shop appears on the interstellar web, selling all sorts of strange things. Sleep-inducing medicinal wine: sleep through the night and have wonderful dreams. Whitening crystal cakes: stay perfectly fresh and healthy despite the radiation. Body-tempering fruit juice: just one little sip, and you'll discover a whole new you! The entire interstellar world goes wild. Who knew improving one's constitution could be so easy? One delicious cake or a cup of juice is enough to give you a new lease on life! The only problem is that the shop sells everything in limited quantities, and even a fortune can't guarantee a purchase. Bigwigs from all over use every trick at their disposal to find the shop. It turns out to be on that heavily irradiated abandoned planet. Now the place is covered in greenery, radiation levels have plummeted, and mutated plants and animals live peacefully alongside humans, all waiting patiently in line. Mutated Animal A: Great Pharmacist, I can lay eggs and catch bugs. You won't regret keeping me, and I'm easy to care for. Just a little medicine each day is all I need. Mutated Animal B: Look at my beautiful, fluffy fur! I evolved it just for you, Great One. You can pet me all you want! I only need half a dose of medicine. Mutated Plant A: Here's a branch I carefully cultivated for you. Just give me a tiny bit of your refined medicine dregs for fertilizer. Mutated Plant B: I don't want medicine or dregs. Just plant me by your front door. I can till the soil and guard the house. I... I can even bloom for you... Everyone: "!!" We must still be dreaming. We actually saw mutated plants and beasts applying for jobs. Premise: A positive, warm, and lovely life
