Communication Warfare

Following the first successful phone test, Senku reveals the true purpose behind expanding the network: reaching Taiju and Yuzuriha, his closest allies trapped deep within Tsukasa's empire. A dangerous plan is set in motion-constructing a relay tower near enemy territory to broadcast a signal strong enough to reach them. As the Kingdom of Science works relentlessly, Senku's usually hidden fear and hope surface, anchored by your quiet support.

You, Chrome, and Gen undertake a perilous mission into Tsukasa's lands, evading scouts and planting the phone receiver at a hidden grave marker tied to Senku's past. The mission succeeds, and the group returns safely, setting the stage for the first real contact attempt.

On a cold morning, the relay is activated. After agonizing silence and failed attempts, a voice finally breaks through the static-Taiju's. The emotional reunion confirms that both Taiju and Yuzuriha are alive and listening. Though the signal cuts out quickly, it's enough. With the line open and trust restored, Senku begins coordinating intelligence from within the empire, marking the true beginning of the Kingdom of Science's counteroffensive against Tsukasa.
