tales of demons and god season 1 anime
Although he was too weak to defend his home in his previous life, Nie Li, a strong Demon Spiritist, rose to the top of the martial world and became the strongest. However, he was killed in battle with the Sage Emperor and six other deity-ranked beasts.
The soul of his son was brought back to the time he was 13 years old. He is the least talented in his class and has the lowest talent. However, he was able to use the vast knowledge he had accumulated from previous lives to train faster than anyone would have expected. He also wanted to help others who had died in his past lives to train faster.
He wants to save the city from being destroyed by demon beasts in the future. He wants to protect his loved ones, friends and family, as well as fellow citizens who were killed in the attack or its aftermath. He also wants to destroy the so-called Sacred Family, who in their past lives arrogantly ignored their duty and betrayed his city.
