The Swordsmanship Master was Reincarnated as the Greatest Genius

Synopsis

“The most loyal sword is always the first to break.”
Shadow No. 1872 of the Paterion family.
He gave everything, but what returned was only betrayal and death.
Just when he thought it was all over,
he awakens anew as Ruin of the Reinhardt family, a prestigious swordsmanship clan in the North.
“This isn’t God’s mercy—it’s a second chance for revenge.”
Now, there is only one goal.
To erase the Paterion family, and all who abandoned him, from this world.
The broken sword will now become the sharpest blade of vengeance.
