Heavenly Jewel Change - Chapter 349

Hiko Hiko, a worker, traveled through Hokage to become a member of the Uchiha, but the timeline turned out to be three years before the night of the genocide.

It coincided with the peak of the village’s suspicion and defense against Uchiha.

Factions in the family fight for power, high-level surveillance, and villagers’ misunderstandings, everything is just like the original work.

If Yan doesn’t act, the final outcome is that the whole family will be sent to the coffin by the filial son Itachi!

Death starts, it is better to ask yourself than to ask others!

Yan can only start to save himself!

Factional battles? Then cut out the faction!

High-level targets? Then change a group of high-level people!

If the internal rescue is not enough, then tear the opening from the outside!

Uchiha self-help guide begins!

Recast the glory of Uchiha!

Remember, my name, Uchihahiko!
