On a rainy night in Zhenguan, the mysterious stranger Yu Dou came to Chang'an with a mechanical dog and a blue spark, waving his hand to save the people, shocking the emperor's heart! Controllable nuclear fusion creates an "artificial sun", nano clusters purify turbid water, and a magnetic giant arm controls the giants - the amazing technology of Gewuyuan crushes the ambitions of the Turks, defeats the army, and scares the grassland! There are also giant webs woven in the sky to annihilate assassins, sparks of fire and sweet rain to break the severe drought, and thoroughfares and sluices running from north to south! The traitor poisoned? The disease is instantly purified! Aristocratic family obstruction? The queen's recovery from serious illness impressed the court! Wherever the spark struck, all the people knelt down, and the enemy chieftains were terrified. The Tang Dynasty used science and technology as its blade to create a glorious and prosperous era, and the power of starting a prairie fire was unstoppable!
