God-Tier Military Industry: From the Start, I Build an Artificial Sun

Lin Mo, the Dragon Kingdom's top military engineer, dies unexpectedly and is reborn as a three-year-old child, bound to the [Strongest Military Engineering System].

To outsiders, he's an autistic genius who only plays with "building blocks." But in the world he has constructed through billions of supercomputer simulations, he's steadily bringing to life the grand blueprint he never completed in his previous life: the "Sky Dome Project."

The story begins with a top-secret package addressed to a three-year-old. When the core components of the miniature controlled nuclear fusion reactor, "Heart of the Sun," arrive at his doorstep, Lin Mo's father, Lin Zhengguo, once a special forces king, has his entire worldview overturned. From initial shock and worry, he gradually becomes his son's "Chief Brain Assistant," personally helping him achieve the feat of igniting an "artificial sun" in their own basement.

This blaze not only alarms the highest levels of the state, but also attracts a mysterious organization known as the "Observers." With their full support, a "Divine Workshop" hidden inside a mountain rises from the ground, and an engineering corps of the most elite "Forgers" becomes Lin Mo's personal team of craftsmen. Yet just as he forges the "keel" of a future aerospace carrier and breathes life into it, an unexpected interference from a higher dimension attracts the true "Observers" from the depths of the universe.

A "game" that will determine the survival of civilization is forcibly brought forward, leaving Earth only one year. Faced with a "gaze" capable of erasing all civilization, this three-year-old chief engineer must lead the entire nation to build, within the Solar System, a [Deep Sea Great Wall] to hold back the gods.
