Republic of China: You Call This an Instructor, the Principal Is Numb

Traveling through the Republic of China and becoming an instructor in Huangpu, Chen Yi smiled when facing this era of lack of medical treatment and backward armaments. "It's time for the world to see what industrial miracles are!" With a drawing at the beginning, he started from scratch and embarked on a journey of construction that defied the odds! [Penicillin purification technology] → Monopolize the life-saving miracle drug, chaebols are holding gold bars to ask for cooperation! [Huangpu Students] → [Special Forces] → [Teaching Corps], combat power increased by 500%! Defeat an enemy division with one battalion! [Abandoned Chemical Laboratory] → [Secret Military Factory] → [Super Era Arsenal]! While others are still pulling the plug, my troops are already equipped: Mauser rifle production line → MG42 general machine gun (nicknamed "Chainsaw") → 75mm infantry gun! He Yingqin wants to pick peaches? In front of him, I used MG42 to carve words on the mountain wall: "My soldiers and guns will recognize people by themselves." (Sneer) The British want to seize my factory? I used penicillin to pry open their market, making them suffer a loss but still have to smile! Li Zongren and Bai Chongxi are at both ends? I slapped the "munitions samples" and "medicines" directly on the table! "You two, can we talk about reunification now?" My goal? First unify Guangdong and Guangxi, and then sweep the whole country! Use China's steel torrent to crush everything! (Note that parallel time and space, I firmly follow the party)
