In Shu Guan's previous life, he had learned in elementary school about a story of a little boy named Watt who, upon seeing steam lift the lid of a boiling kettle, later invented the steam engine.
Of course, this was just a text written for elementary school students, simplifying a matter that was incredibly complex and arduous into the simplest language possible.
In fact, Watt was not the true inventor of the steam engine but merely an improver; he was simply the one who created a truly practical steam engine.
But even before that, the world had already completed a profound accumulation of basic theoretical knowledge in all areas, and likewise, countless engineers had made various improvements to the steam engine.
This, after all, is the law of technological development; the brilliance of genius is important, but the spark was already nurtured and ready to be lit long before.
"This can't be possible!"
So, it was Shu Guan's turn to shake his head and say it wasn't possible.
