Senku's team flees with the captured scientist Xeno in a small boat, pursued by Stanley Snyder's elite unit. Their destination is South America, to find the origin of the petrification beam. Meanwhile, Ginro is held hostage on Stanley's ship. When Matsukaze – himself severely injured – tries to intervene for him, Ginro, under pressure, reveals their travel destination to South America.

During the escape, Senku and Xeno, despite their rivalry, begin exchanging data about the global petrification. Both confirm that the signal originated from the moon. Using Byakuya's records of the astronauts and physical models, they analyze the beam's trajectory: The petrification wave spread at 32,000 km/h, reached an altitude of 20,000 meters, and hit Japan with a 15-minute 20-second delay compared to the USA.

By calculating the shortest Earth distance and the angle of incidence, they pinpoint the exact origin: 3°7' south latitude, 60°1' west longitude in the Brazilian rainforest. Meanwhile, Stanley launches a pursuit with his carrier ship to retrieve Xeno – with Ginro and the wounded Matsukaze on board.
