Baigongshengyu: Non-Attacking Heavenly Craftsmanship

The rebellious agency genius who was the loser of the Qin Kingdom joined forces with the girl of the Mohist Qi Sect to secretly build a mobile defense city fortress "Non-Siege" underground in Xinzheng to fight against the Qin Army's steam-tracked steel behemoth "Whale Swallowing Beast" that can physically crush the Six Kingdoms. In 307 BC, King Wu of Qin ordered Gan Mao to attack Yiyang, an important town in South Korea. Under the crushing power of the Gongshu's overbearing agency war beast, the "Whale-Swallowing Beast" - a ten-foot-tall steam crawler monster that sprayed fierce fire oil, Yiyang fell and 60,000 Korean troops were massacred. King Wu of Qin personally visited the front line, intending to take advantage of the victory and advance eastward to completely annihilate Xinzheng, the capital of South Korea. Gong Shupan, a young machine genius of the Gongshu family, suffered a mental breakdown after witnessing the machine beast he participated in the development being turned into a tool of slaughter, and defected with the core design. In the ancient copper mines underground in Xinzheng that have been mined for hundreds of years, Gong Shupan met Han Wei, a girl from the Mohist Qi sect, as well as masters of iron smelting, carpentry, copper smelting and other craftsmen from various countries. Faced with the pursuit of Qin's Heishuitai spies, the cleanup of Gongshu's family, and the betrayal of the Korean court to cede territory and seek peace, Gongshupan and Hanwei joined forces and decided to transform the old defense system in the underground mines into a movable mobile fortress - a "non-siege city" to resist the behemoths of the Qin Dynasty. Outside the east city wall of Xinzheng, a once-in-a-century heavy rain and flash flood erupted. Two ancient wooden and stone behemoths, representing the pinnacle of machinery in the Warring States Period, started a violent head-on collision in the torrent.
