That Year, That Sword, That Mute Boy

[No system, time travel, slow heat, single female protagonist, ancient detective, swordsmanship] Lu Liansheng, who accidentally traveled through time, was imprisoned for no apparent reason simply because he was the only practitioner in the county. When he first entered the cultivation path, he had almost no fighting power at all. What's even more tragic is that I obviously have a lot of grievances and want to complain, but I am mute... At first, he only wanted to be rich and content, but after seeing the injustice of the world and finding the girl he liked, he became more determined to practice hard. Fortunately, there is such a sword, spanning a hundred years, just for Lu Lian. More than ten years later, the boy turned into a young man in the blink of an eye. When he stepped into the hot and churning sea of evil fire clouds with his sword in hand, he suddenly discovered that the history of this world is always repeating itself... Helpless people pass away, and the sword of déjà vu returns.
