Is the System Fake? Still the Fox Fairy Sister Is Soft and Fragrant

The powerful Yue Yingli of the ancient demon race died in a catastrophe, and the remaining soul possessed the ice fox who desperately tried to save him, and fell asleep in the forgotten interface. When he was down and out, Lu Qi accidentally picked up and adopted a little white fox, and they lived together for more than ten years. Until one day, the sleeping soul in the little fox finally awakened... Later, the "system" joined in, thinking that he could become the son of luck, he could upgrade while sleeping, and all the beauties would be given to him for free... But he didn't want to travel to another world, and from then on he began a magnificent and fantastic journey as a fairy. Lu Qi hoped to rely on the system to survive, but this system was a bit strange. The tasks were weird, rewards were withheld, and sometimes he couldn't be summoned... Forget it, the system couldn't count on it, so he might as well just stick with it. It's slow but doesn't abuse the protagonist, it's brainless and doesn't overwhelm its wits. The female protagonist has many roles, she's very fairy and cool.
