Tập 12: Senku tiết lộ mục đích thực sự của ngọn giáo bạc là một cảm biến khí cho axit sulfuric.

The silver spear made by Senku is revealed to be a sensor to detect poisonous gases coming from a pool of sulfuric acid, which they need for the antibiotic. Knowing the risks involved, Senku offers to teach Chrome everything he knows about science on the off-chance that he dies, but Chrome refuses, instead proposing a tag-team style approach. While gathering the acid using special gas masks, Chrome nearly falls into the pool but is saved by Ginro, who overcomes his fear and helps the duo obtain a bottle of the acid. (Source: Wikipedia)
