The Strongest Training in the City

After a thousand years of dreaming, I experienced ups and downs in my life of cultivating immortals. I never expected that I would return to the time before time travel. I thought that the modern city is a peaceful place where you can cultivate immortals, be popular with girls, pretend to be awesome, and slap the second generation in the face. But who would have thought that his sister's current city is more dangerous than his mother's world of immortality? This novel and its characters are purely fictitious.
