During the Qian Dynasty, Emperor Li Yi indulged in pleasure and neglected government affairs. The country was in crisis under his mediocre rule. One mysterious night, a strange light flashed, and Li Yi traveled to the distant modern lighthouse country.
When he first arrived in the Lighthouse Country, Li Yi was isolated, unable to speak the language and penniless. In order to survive, he bravely ventured into the dangerous black area, cleaned toilets in restaurants, and was bullied. But the desperate situation inspired his fighting spirit. With tenacious perseverance, he studied English hard and worked hard all the way. He successfully obtained a master's degree and a doctorate, and achieved a counterattack from a loser to an elite.
An accident caused Li Yi to return to Daqian. Relying on the knowledge and insights accumulated in the Lighthouse Country, he vigorously promoted reforms, developed industry, innovated education, and reorganized armaments. Daqian gradually became prosperous and its national power grew.
Later, Li Yi discovered a way to travel back to the Lighthouse Country. With his wealth and wisdom, he ruled the gangs in the Lighthouse Country, vigorously popularized Chinese culture, and made Chinese language and Chinese culture widely spread locally.
However, frequent travels have broken the balance between the two worlds, and strange changes continue to occur. Standing at the crossroads of destiny, how will Li Yi make a choice, and what changes will it bring to the future of the two worlds?
