The highly toxic spores of poisonous mushrooms pose a problem, but they're not entirely unsolvable. Basically, any hunter with a bit of experience would carry protective masks, which can shield the user's face, filter the air, and isolate harmful substances from it. Naturally, the toxic spores would also be isolated.
Tang Yiyi wore a system-issued protective mask, which an ordinary person wouldn't notice. Even Song Yunxiu would only be able to see the thin mask covering Tang Yiyi's face when using his superpower. Song Yunxiu also had a bio mask, though not as powerful as Tang Yiyi's.
Nonetheless, his space button contained plenty of weapons and tools, fully equipped, and he wasn't worried about those toxic spores.
