Dr. Stone: Science Future Part 3 Episode 1: Future Engine

Senku Ishigami and Dr. Xeno stand under the moonlight, two minds aligned on an impossible goal: the moon. Senku's smirk, mirroring Xeno's, sets a determined tone. The petrification of humanity, a global tragedy, is the stark backdrop for their ambition. They see no other way but to confront the source directly, a bold declaration of intent.

Dr. Xeno officially joins the science team, a development that raises eyebrows and immediate suspicion from Taiju and Gen. He wastes no time demonstrating his scientific prowess, first extracting argon for a simple lamp, then revealing a Geiger counter. This device allows them to locate the rare earth elements essential for their grand plans. The team's excitement at discovering these vital minerals is palpable, even if Taiju's fear of radioactivity is comically exaggerated.

The old Perseus-go emerges from the depths, a ghost of its former self, rusted and dilapidated. Kaseki mourns its state, only for the team to immediately begin dismantling it. Ryusui Nanami confidently declares it 'iron recycling', a brutal practicality that overrides sentiment. The ship, once a symbol of their journey, becomes raw material for something greater.

The team embarks on a massive industrial effort to create 'superalloy', a process Dr. Xeno details with gleeful precision. Metals are melted and combined, culminating in the triumphant reveal of stainless steel. The first use? Not spaceships, but Senku's eccentric declaration of 'canned goods!' This seemingly mundane invention, however, promises preserved food for centuries, and with it, survival.

With their new materials, the efforts to revive petrified humans intensify. Taiju joyfully pours revival fluid over Tsukasa, bringing him back to life, symbolizing humanity's reawakening. Simultaneously, Dr. Xeno communicates via radio, revealing his past connection to the petrification event and his former team. He reminds everyone that a moon voyage requires countless more materials scattered across the globe.

Dr. Xeno and Senku Ishigami formally divide their immense responsibilities. Xeno will focus on the rocket engine, Senku on the new ship. Xeno unveils a terrifying machine designed to create a superior superalloy, one that produces a lethal poison. He declares himself the 'scientist of darkness', willing to embrace morally ambiguous science for progress. Senku, in turn, accepts the mantle of the 'scientist of light', guiding humanity forward.

Under the combined leadership, the team transforms the landscape, digging relentlessly for ores and establishing 'Superalloy Town.' Taiju and Kohaku demonstrate fierce teamwork. The village thrives, a testament to their collective effort and the hope for a united humanity. Dr. Xeno and Senku Ishigami stand back to back, their contrasting roles solidified, ready to confront the unknown with science.

A new challenge arises: fuel for their ship. Suika despairs at the lack of petroleum, but Senku Ishigami promises 'future energy.' He reveals the answer: biofuel, generated from fermenting 'raw garbage,' including... poop. The team's disgust is immediate and comical. To store this peculiar fuel, they create a perfectly spherical tank using an internal explosion, a truly unconventional method.

Dr. Xeno introduces an electromagnetic induction heater, a massive machine designed to melt superalloys that resist conventional heat. Meanwhile, Senku Ishigami reveals the Fischer-Tropsch method, a way to convert their raw garbage biofuel into liquid fuel. Dr. Xeno then unveils an ultimate 'superalloy within superalloy,' a metal capable of withstanding extreme conditions for rocket engines. Taiju can only gape at the wonder of it all.

Months of relentless labor pass in a blur of digging, melting, and building. Finally, the fruits of their labor are revealed: a gas turbine engine, roaring to life with an impactful jet of light and frozen water. Dr. Xeno declares this 'Level 1' engine just the first step towards a 'Level 99' moon engine. He and Senku Ishigami acknowledge their 'brief collaborative work' is ending, their paths diverging as their immediate goals are met.

With the first phase complete, Ryusui Nanami announces a strategic division into three teams. The 'Superalloy Town Remaining Team' will continue refining materials, the 'Corn City Returning Team' will establish corn production in America, and the 'New City Advancing Team' will cross the Atlantic, circumnavigate the globe, and gather spaceship materials. The enormity of the task is met with a mix of excitement and trepidation.

The magnificent New Perseus-go is unveiled, a sleek, powerful vessel that cuts through the water at an astonishing speed. Ryusui Nanami proudly boasts of its 10,000 horsepower and its ability to cross the Atlantic in a mere week. The team, initially overwhelmed by the equatorial heat, finds relief in the ship's air conditioning, a small comfort that reminds them of civilization's return.

As they voyage, Gen Asagiri reminds everyone of their reliance on Morse code for long-distance communication. Taiju, observing the full moon, suddenly connects the petrification event to Why-Man's initial appearance. To everyone's shock, Taiju intercepts a message. Senku Ishigami confirms that Why-Man has been 'leaking' information. The message is simple, yet terrifying: 'Do you wanna die?'
