Transmigrating into the Uchiha, only to become an orphan after the clan's extermination, with mediocre talent and enduring the Byakugan's disdain?
Just when I thought my life was hopeless, I unexpectedly awakened the [Martial Arts Legacy System]!
"Ding! Do good and uphold justice, reward: Eighteen Dragon-Subduing Palms!"
"Ding! Help others, reward: Lightness Skill, Wave-Treading Steps!"
"Ding! Defeat a powerful enemy, unlock the Mangekyō Sharingan!"
From then on, Konoha had an unconventional "heroic shinobi."
Others formed hand seals to use ninjutsu; he used the Wave-Treading Steps and a single Dragon-Subduing Palm to break every technique!
Others trained hard with Shuriken; he wielded the Six Paths Sword at his fingertips, slaying enemies with invisible sword energy!
At the Chunin Ninja Exams, he faced the Hyuga prodigy with Tai Chi swordsmanship!
When Konoha fell into chaos, he guarded a sanctuary with nothing but his sword!
The Akatsuki? Watch me use Beiming Divine Art to drain your chakra!
Deva Path Pain? Take this combined ultimate technique: Divine Sword Conquest!
Kaguya seeks to destroy the world? I have one punch, named: Heaven-Splitting Earth-Shattering!
As chakra merged with internal energy, and the Sharingan discerned the ultimate principles of martial arts, he became a master whose martial arts reached the divine!
Yet one day, the System would leave. The path he chose was...
To establish a school among the ruins and spread his teachings throughout the world!
This is a story about spreading the "Way of the Hero" through the shinobi world.
