Meet back at 6:30 to discuss how to enhance the MHD shielding as Professor Xu suggested.”\u003C\u002Fp>\n\u003Cp>“Alright.”\u003C\u002Fp>\n\u003Cp>They packed up, prepared to go eat, and began chatting.\u003C\u002Fp>",636,"2026-06-20T21:06:45.888Z",1,"Qwen3-Next 80B","bd1e375a4a7cbdd95c0aa71b33641242cc222949eff8d24a384aac4a9acde9ab","i-m-focused-on-science-but-you-want-to-trick-me--chapter-765","i-m-focused-on-science-but-you-want-to-trick-me--chapter-763",790,"https:\u002F\u002Fnovelzhen.com\u002Fimages\u002Fcovers\u002Fi-m-focused-on-science-but-you-want-to-trick-me--cover.jpg"]
