Eternal life begins with saving my clan - Chapter 121: Cultivation Technique and Bottleneck

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!

Hace 24 años, el mundo colapsó. Un virus conocido como Eclipse transformó a la humanidad en criaturas mutantes, llevando a la sociedad al borde de la extinción. Las ciudades se convirtieron en ruinas, los asentamientos luchan por sobrevivir, y la verdad sobre el origen de la infección se ha perdido en el tiempo.En este mundo roto, Kai, un viajero solitario y mercenario de intercambio, sobrevive negociando Obsidianos, la única moneda de valor en la nueva era. Su vida cambia cuando cruza caminos con Lía, una misteriosa joven perseguida por mercenarios. Su única posesión es un antiguo colgante de Obsidiano, cuyo secreto podría cambiar el destino del mundo.Juntos, se ven envueltos en una conspiración que los lleva hasta el Laberinto Ancestral, un lugar prohibido que esconde la verdad sobre el Eclipse. Perseguidos por un ejército liderado por el despiadado Voss, enfrentándose a infectados más allá de la comprensión humana y descubriendo que su pasado está conectado al desastre, Kai y Lía deberán decidir si la verdad merece ser revelada… o si es mejor que permanezca enterrada.Cuando la última puerta del Laberinto se abre y los ecos del pasado despiertan, solo una pregunta queda en el aire:¿Es el Eclipse el fin de la humanidad… o su evolución?

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory?
