… but I'll bite.
just open the tor browser, and for 8kun put:
http://jthnx5wyvjvzsxtu.onion/qresearch/catalog.html
in your address bar.
From there go as usual. For this bread, for example, it'd be:
http://jthnx5wyvjvzsxtu.onion/qresearch/res/12443422.html
Other than that, maybe you should read up on tor in general, tor nodes etc.
Don't know where to start, but tor has a complete different address scheme (.onion endings). There are also search engines, but much more limited.
e.g. see: https://drfone.wondershare.com/dark-web/tor-search-engine.html
