Modern Professor Yongzheng was seriously ill and started to save himself with a bowl of salt water, starting from then on the road of "hard-core industry to save the country". Kowloon seizes the direct descendant? I first use statistics to calculate probability. Party strife in the court? I took physical chemistry to open a factory. When brothers were fighting for the throne, I was teaching calculus to orphans; when Qianlong was still memorizing the Four Books and Five Classics, my steam engine was already roaring - who said time travel requires palace fighting? I want to ignite the industrial revolution with my own hands.
