In the summer of 2018, Lin Yuan, a computer graduate from Yuejiaqiao Town, Yiyang, returned to his hometown to participate in the digital surveying and mapping of ancient bridges. When he touched a blue brick with strange patterns engraved under the foundation of the bridge, the world was spinning - he woke up five years later in Shaoxing, Southern Song Dynasty, and he was lying in an unnamed ditch covered in mud.
In the distance, the flag of the Yue Family Army was roaring.
Lin Yuan cannot ride a horse or understand martial arts. His only weapons are the algorithms, logic and engineering thinking in his mind. He relied on a copy of "Eight Strategies for Pinghu" to crack open Yue Fei's big account, used path planning to defeat Yang Yao's water village, and used binary semaphore to rewrite battlefield communications. Everyone in the army called him "Mr. Bridge Counter" - because the stone bridge he presided over the construction convinced the soldiers more than any sword.
However, history can never be easily tampered with. He could not save Yue Fei, nor could he prevent the bridge from collapsing several times in the thousands of years of wind and rain. On the eve of his departure, he encrypted all his memories into a libretto and gave it to the Yiyang fisherman's flower drum troupe.
Nine hundred years later, Lin Yuan returned to 2018 and sat under the ancient stage in Yuejiaqiao Town. An old Huagu Opera artist on the stage was singing a piece of "Yuejiaqiao" whose origin no one knew -
The "young man who counts bridges" in the play is exactly the same as him.
He suddenly understood: This bridge has never been forgotten. It keeps singing.
