Mountains and Rivers Test Swords and Fireworks in the World

When a chemistry teacher meets a Tang Dynasty knight, a passionate adventure spanning thousands of years. Chemistry teacher Shen Zhibai accidentally traveled to the Tang Dynasty due to an experimental explosion, and accidentally rescued the knight Xu Xingzhou who was wanted by the court - he turned out to be the son of Xu Jingye, the general who rebelled against Wu Zetian. One is a complaining young man full of modern science, and the other is a cold and aloof swordsman. The two are forced to embark on the road to escape. With his knowledge of chemistry, Shen Zhibai often came up with strange tricks: using saltpeter to make ice to outwit fire attacks, using vinegar to detoxify sweating pills to see through black shops, and even invented black technologies such as bamboo telescopes and simple gunpowder. From the murder of a Yangzhou salt merchant to the scandal of imperial examination fraud, from the mysterious death of a border war horse to the crisis at a palace night banquet, the two work together to solve the mystery and gradually uncover the shocking conspiracy behind it. Under the picture of the prosperous Tang Dynasty, undercurrents surge, and their choices will change the trajectory of history... This novel and its characters are purely fictitious.
