Refining Elixirs and Raising Pixiu, the History of My Struggle to Cultivate Immortality

The time traveler Chen Yue was bound to the Ten Thousand Worlds Lottery System, and he got the god-level ability [Lion Awakening] in the first lottery - feeding the treasures to the beasts, there is a chance of getting better rewards! Chen Yue was ecstatic: This is the rhythm to be released! Then he drew the first beast - a furry little beast. Chen Yue: Hey, hey, try the water. The little beast took a pill, burped, and spit out nothing. Chen Yue:? What about the promised reward? System: Host, there is a probability, not a certainty~ Chen Yue: Okay, let's take another one. Still no response. One more. No. Come again... Half a year later, Chen Yue invested all his wealth into it, and the little beast gained three times more weight. Chen Yue was left penniless, and not a single reward was triggered. He finally couldn't help but ask the system: "What is the probability?" The system was silent for three seconds: "Host, are you sure you want to listen?" "... Say." "0.3 Out of 10,000 meow~" Chen Yue's eyes darkened. What was even more frustrating was that he finally knew what kind of thing it was - Pixiu, an ancient ferocious beast that could only go in but not get out.
