Chrome and Magma struggle with Ukyo, while Senku, gets his hands busy with building up an invention; a new hope.

Tsukasa and Hyoga are coming to capture the miracle cave. The Kingdom of Science must buy Senku and Chrome some time to turn the tide, or it is all over.

While continuing to use the hot air balloon to search for the oil, it's decided that Ishigami Village needs to take up agriculture to prevent future food shortages, as well as to produce preserved food for their upcoming sea voyage.

The Perseus arrives at the treasure island. A recon squad consisting of Senku, Soyuz, Kohaku, and Gen set off to locate the platinum and make contact with the islanders. Ukyo later discovers something on the seafloor and send Ginro to investigate.

Kohaku is forced to destroy Ryusui's statue to prove that she isn't a spy.
