I recommend the book, The Long Wind Doesn't Know the Distance. Although it was a romantic novel about the pain of youth, the main character also had elements of rebirth. At the same time, the protagonist's grandfather was an old revolutionary, and the protagonist's parents also had conflicts with his grandfather. I hope you like my recommendation. Muah ~
This was an urban novel where the protagonist and his grandfather depended on each other. His grandfather was a veteran who taught him Bajiquan. Later on, when his grandfather died, the main character reunited with his parents.
It was quite common for the old chief to be his grandfather in novels about rebirth because the background of the characters and the historical background were often reconstructed. In this case, some novels might set the old chief as grandpa because grandpa was a very common title in traditional Chinese culture to express respect and care for the elders. At the same time, maternal grandfathers were usually regarded as important figures in the family with a certain amount of power and status.
They might be similar in appearance. For example, they could have the same eye color or the shape of their nose.
The moral could be about respect for the elderly. In the story, perhaps the grandson learns to value his grandfather's wisdom and experiences.
The male lead of Hegemon of Heaven was called Yang Tian, which matched the description of the title. In the novel, Yang Tian was besieged and killed by seven elders before he was reborn as the Young Marquis of the dynasty. I hope you like this fairy's recommendation. Muah ~π
His grandfather could be a very strict and traditional ninja. He might have high standards for Naruto in terms of ninja skills and discipline.
It could be an old and powerful wizard who has been in hiding for years. Maybe he was a friend of Dumbledore's but had some differences with him, so he stayed away from the main events in Harry's life until now.
The book 'Battle Break's Strongest Villain' met the requirements. The main character, Hun Tianchen, was the young clan leader of the Hun clan. His father was Hun Tiandi. I recommend this book to you, I hope you like this fairy's recommendation, muah ~ππ
πThe novel that I strongly recommend to you is "I am the heir of a consortium after rebirth". The protagonist of this novel returned to his infancy after his rebirth. His grandfather's lifespan had come to an end, but he had successfully bought a week for his grandfather. This novel was a novel about the rebirth of the city. The ups and downs of the plot and the ingenuity of the protagonist were admirable. If you like this kind of theme, don't miss this novel! I hope you like this fairy's recommendation. Muah ~π
The main characters are obviously the old grandfather and his grandson.
