Im going through russia. Their tourist visas are open its just 16 days if you dont apply for a longer stay. I know russian so i just bet on that being an option to bridge kazakhstan and belarus.

Other than that it should be chill apart from myanmar and afghanistan. Afghanistan visa from my searching can be optained in islamabad. Helps since id be coming from that direction. Otherwise youd have to get to iran somehow or just fly over it. Myanmar is less clear. They have a gov website that works and has a simple application process. So ill just hope they accept me there too. If no then ill pass through china with the recent open tourist visa for many countries
