"Ding! You spied on a master assassin. Observation Points +50. [Rainstorm Pear Blossom Needles] has reached perfection!"
"Ding! You watched the Sword Immortal open the Gates of Heaven. Observation Points +100. You've comprehended the peerless sword intent [A Sword Across the Ages]!"
After transmigrating to the Great Jin, Ye Guan gained the Martial Arts Observation System.
He can study every martial art under heaven and solve cases with uncanny insight!
When the Six Fan Gate was at its wits' end over an attempted assassination of a prince, Ye Guan happened to pass by.
"No need to investigate. The killer used the Wang family's 'Sword of Heaven and Earth.' I happen to know it, so I'll catch him while I'm at it."
From then on,
the martial world had a new legend who played by no one's rules.
Demonic Cult Leader: "I've spent sixty years cultivating my Apocalyptic Demonic Art. How can he watch it once and use it better than me?"
Sect Patriarch: "I warned you all not to fight in front of Ye Guan! The secret arts we've guarded for generations became standard issue for the Imperial Guards the very next day!"
Ancient Clan Patriarch: "Tell every family disciple to stop practicing at once! That brat Ye Guan is coming to visit our estate again!"
Great Jin's Empress: "With Minister Ye by my side, my realm is as secure as a mountain. Wait... did he look at my imperial bedchamber last night too?"
Ye Guan: "I see, I see, I see everything!"
The plot is good, but the battle scenes need to be more polished.
