what is that random invite to LHC to fight the turtle boss give you if you win?

the one that randomly pops above ur head with a red envelope?

kk, just beat him, if you say that you don't deserve the treasure, what happens?

I chose the first option and got a ani's box, does anything good come from there?

i have gotten advance potential scrolls, earring int 60% x3, many untradable pots, and some etc i cant remember its name.
