Fire the Smoke Signal

In a bold move to counter Tsukasa’s overwhelming strength, Senku creates gunpowder using scientific principles from the stone age. The explosion successfully generates a massive smoke signal, signaling his survival. Soon after, Yuzuriha notices another smoke signal in the distance, suggesting that more humans may have awakened. Senku now faces a dangerous dilemma: continue using explosions to communicate and risk exposing his location to Tsukasa, or remain hidden and lose a potential ally.
