In his past life, although too weak to protect his home when it counted, out of grave determination Nie Li became the strongest Demon Spiritist and stood at the pinnacle of the martial world. However, he lost his life during the battle with the Sage Emperor and six deity-ranked beasts. His soul was then brought back to when he was still 13 years old. Although he's the weakest in his class with the lowest talent, having only a red soul realm and a weak one at that, with the aid of the vast knowledge which he accumulated from his previous life, he decided to train faster than anyone could expect. He also decided to help those who died nobly in his previous life to train faster as well. He aims to protect the city from the coming future of being devastated by demon beasts and the previous fate of ending up destroyed. He aims to protect his lover, friends, family and fellow citizens who died in the beast assault or its aftermath. And he aims to destroy the so-called Sacred family who arrogantly abandoned their duty and betrayed the city in his past life. (Source: Goodreads)
This is the first anime that made me look for the manga, then the light novel. The plot is captivating for my preference and easily made me look pass the flaws of the animation. Unfortunately, the author did not complete his story and has decided to drop it… which is severely depressing it’d take years for me to move on.
Animation wise, 7mins episode, this shit is undeserving to the story. 3D animation does look good but not very smooth. Doesn’t have unnecessary flashy scenes and keep to the plot, which is something i cannot find in many anime. First few episodes move at a very slow pace, since 5min playtime each. However, after completing all 40 episodes. I wouldn’t want them to replace the animation since i find it rather appropriate. However, i urge them to standardize an episode to 20mins+
All in all, the animation is weak but the plot and world of this show is boundless. And it was an extremely sad moment to find out the author stopped writing this series from lack of motivation; and started a few other series. I cannot think of any other anime that are similar to this other than Reikenzan, imo 8:10 compared to yaoshenji. There are not many plots that as deep and detailed compared to this in their universe other than Harry Potter. IMHO.
Some animes that i loved before finding this are Overlord, Mahouka Koukou no rettousei, youjo senki and NGNL.
