Lu Heng traveled through time. He had no system or magical skills, only the memories of a postgraduate student in civil engineering and chemical engineering who occasionally experienced network outages.
In this barbaric ancient Shu, where witches roamed the land and floods occurred every year, he picked up a stone shovel and vowed to use pure technology to teach these superstitious ancients a lesson.
As long as he sees the real thing, he can make crazy trials and errors and piece together the modern knowledge in his mind. This "humanoid self-propelled industrial encyclopedia" is his most hard-core plug-in.
Facing the backflow of floods and mudslides, Wu Xian was about to throw Lu Heng into the river as a sacrifice to appease the god's anger. Lu Heng used glutinous rice and lime to burn a cement dam on the tidal flat!
When the surrounding powerful barbarians wielded stone axes to grab food, Lu Heng silently took out his newly-baked steel knife, and used the first barrel of refined snowflake salt to bribe all the other party's spies.
"The great witch said this was the coming of heavenly fire?" Lu Heng looked at the simple chemical magic in the temple and sneered, then used sulfur and white phosphorus to perform a "real roar of thunder" in front of the two armies.
From a homeless tribal orphan in the river valley to a famous master of all craftsmanship, Lu Heng took infrastructure farming to new heights in ancient Shu.
"Stop worshiping God. The great witch really doesn't understand science. Come and move the bricks with me, the foreman, and let's build a heavenly kingdom!"
