People are on the parallel wasteland Blue Star, and they start with a double door.
The technological faults of this world, which cannot even produce bullets, are being invaded by ferocious foreign empires.
Lin Chuan originally wanted to make some profit from the scrapped steel pipes and fertilizers, until he met Brother Yunlong.
"Brother, the caliber of your steel pipe is large enough. Can it be used as a cannon barrel?"
Lin Chuan: "Are you crazy? This is a sewer pipe... Wait, it seems that adding a gas tank will work?"
A month later, the painting style completely collapsed.
Thousands of "gas tank heavy artillery" blasted the Imperial Vanguard Army into the moon's surface, and thermobaric bombs modified from commercial herbicides instantly drained the oxygen from the canyon.
The marshal of the enemy's expeditionary force wrote a suicide note overnight: "The other side is not a human army at all, it is the living king of hell!"
Looking at the "Pangu Military Industrial City" rising from the ground in Linchuan, Blue Star executives trembled: "Mr. Lin, please stop building it. You will rewrite the global rules!"
Lin Chuan: "Why are you panicking? I just got a few civilian weather rockets, and I plan to go to the other side of the sea to plant some mushrooms!"
It's all fun without thinking...
