Even blind box hunters don't choose their partners? I got Su Daji from my blind box!

Everyone who turns 18 is forced into the "Blind Box Survival Game".
The game starts with five blind boxes: weapons, cultivation techniques, spirit pets, elixirs, and companions.
Textbook warning: Even the most hardcore gamers won't choose the Partner Blind Box; it will only produce a burden. Choosing it will lead to certain death!
Lin Xiao, a transmigrator, awakened the "All-Knowing Eye," which allows him to see the return rates of all things.
The "weapon blind boxes" that everyone's scrambling to buy have a return rate of -500%?
The partner blind box, which was seen as a suicide option, unexpectedly revealed a unique [highest return rate in color ∞]!
The entire school mocked him, but Lin Xiao recklessly went all in!
The blind box is opened, revealing a nine-tailed demon that blots out the sky, and the peerless enchantress Su Daji kneels in submission.
"Please feel free to give Daji your orders, Master~"
While other examinees fought desperately amidst the horde of zombies, they were relentlessly pursued by the third-tier zombie king.
Lin Xiao was wiping Daji's hands, because the BOSS's blood had almost splattered onto his white shirt.
The next second, the Corpse King was torn to pieces, and the mythical reward was his!
Obtained the divine-level cultivation technique, "Yin Yang Harmony Emperor Scripture".
Can you replicate 100% of Daji's combat power by making physical contact with her?
The global leadership is stunned.
You call this a burden? This is clearly a mobile mythical catastrophe!
……
Later, when the moon goddess Chang'e, the seraphim, the succubus queen...
One after another, mythical-level partners were drawn out by him.
Lin Xiao looked helpless.
"Stop ordering Goddess Partner products! I'm completely drained!"
