22

In the search for tungsten, Senku, Chrome, and Magma search for a nearby cave. After encountering a mica vein, Magma tries to save Senku from falling into a sinkhole, but both eventually are trapped. Chrome saves them both by filling the sinkhole with water. The three hurriedly return to the village after encountering a deposit rich with minerals to make it in time to celebrate Senku's birthday. While the three were gone, Gen and the village built an observatory for Senku. (Source: Wikipedia)
