NOTE:

the novel is written by: Ye Nan Ting Feng who also wrote the strongest hokage and one piece talent system.

his work was translated by: TranslatinOtaku who have done an amazing job with two of his work that is God of soul system and the strongest hokage you can go read the whole novel in their site by the same name :TranslatinOtaku.

if you want to read the strongest hokage in webnovel instead of a Web format you search in Webnovel for: HolyOniiSama who have uploaded the novel here by the name of naruto: the Godlike hokage.

as for his other work that is not translated by: TranslatinOtaku that is one piece talent system you can go to DM translation in Web format or here in webnovel that was uploaded by: Franxiscus_Siregar.

As for this work that is God of soul system you can find it in here but up to only 347 out of 709 chapters or other ones that not even more then 50 so I will try my luck and do the whole thing in here.
( I owe nothing of the following work nor its characters or anything of like the rights of book goes to its author and its translator, any anime mentioned in this belong to its respective owner)
