Question about Immortal Tresures

For anyone following the latest Battle Pass, in the immortal III Treasure there is an ultra rare Monkey King immortal.

A few people on the market place somehow are selling a ton of these, one guy in particular is selling like 15+ of them.

Obviously it's possible he maybe purchased a TON of battle levels and happened to get SUPER lucky... but i mean this looks like he somehow hacked a bunch in order to sell so many on the Market.

Any known hacks for such a thing? as was hoping to snag one of those up for myself.

No this is not possible unless you want to do something illegal.
