The Time-Space Compass: The Ming Dynasty's Imperial Preceptor

Lin Qiu, a graduate student in history, accidentally transmigrated to the fourteenth year of the Zhengtong era of the Ming dynasty. Bound to the Space-Time Compass System, he became the wrongly identified successor to the Pavilion of Heavenly Secrets. From turning the tide amid the flames of the Tumu Crisis to being tempered by the blood and fire of the defense of Beijing; from improving firearms and reviving the Institute of Practical Studies to spur the dawn of science and technology, to navigating the imperial court and the martial world to foil conspiracies and shape national policy... He wielded modern knowledge as his blade and the duty of a man of the state as his shield. As he rewrote history, he gradually uncovered the shocking secret behind the System, a secret spanning time and space.
