Li Xiaole, an ordinary student, accidentally traveled to the Zhenguan period of the Tang Dynasty and turned into a dwarf only one meter tall, with a mysterious head drop on his body. At the critical moment, the "I Want to Seal the Sky" system is activated, allowing him to learn various head-lowering techniques. Li Xiaole thrives in Chang'an City with his lively and cute personality and weird head-lowering skills. He first gave the wealthy businessman who laughed at him a "laughter" to make him look embarrassed in public; then he used a "love trick" to make the proud princess fascinated by him; and he even used a "amnesia trick" to resolve the court conspiracy. As his abilities improved, he discovered that his head-dropping was actually related to the Dragon Vein of the Tang Dynasty, and a battle for hegemony between the head-dropping and sealing the sky was about to begin. Li Xiaole must use the head-lowering technique to smash the conspiracy, protect the Tang Dynasty, and at the same time unlock the secret of his dwarf origin.
