1969年，屠呦呦加入"523任务"，负责从中国传统医药中寻找抗疟新药。接下来的两年里，团队经历了190余次失败。这个闯关重现了其中五个关键的推理节点——每一步，你将站在当年研究者的角度，判断"下一步该怀疑哪个环节"。这不是医疗知识测试，答案没有惩罚，选错同样会看到历史上实际发生的过程，并盖上一枚不同颜色的印记。
In 1969, Tu Youyou joined the national "Project 523" to search for new antimalarial drugs within traditional Chinese medicine. Over the next two years, her team endured more than 190 failed attempts. This quest recreates five key reasoning junctures from that process — at each step, you'll stand in the researchers' shoes and judge "which part of the process should be questioned next." This is not a medical knowledge test; there's no penalty for a wrong guess, and each choice earns a stamp of a different color revealing what actually happened historically.
本闯关呈现的是科学研究方法与史实过程，不涉及任何疾病的诊断或治疗建议。青蒿素相关的临床用药信息请以现行药典与医嘱为准。
This quest presents scientific research methodology and historical events only. It does not offer diagnosis or treatment advice for any condition. For clinical use of artemisinin-based drugs, consult the current pharmacopoeia and medical professionals.
从"水煎法为何屡屡失效"到"过氧桥基团为何怕热"，屠呦呦团队走的这条路，本质上是一套严谨的排除法：每一次失败都在缩小问题的范围。1971年第191次实验，青蒿素结晶终于出现。
From "why does decoction keep failing" to "why the peroxide bridge fears heat" — the path Tu Youyou's team walked was, at its core, a rigorous process of elimination: each failure narrowed the range of possibilities. On the 191st attempt in 1971, artemisinin crystals finally appeared.
