Thrown into a Parallel World by a Dragon

On a rainy night, Xu Feng witnessed the appearance of a "dragon" under his persimmon tree - horns, snake body, black scales, long beard, and his eyes met in the lightning. The next second, the world line was quietly rewritten: he woke up and found that his "mother"'s temperament had changed drastically, the old house had turned into a strange old house, the bluestone alley, the old tree hugged by two people, and Xiao Chen Lin's laughter and curses all told him that this was not the original world.
