Rubik's Cube Building

The story

Lake, a sixth grade pupil, is facing severe exams, and his parents have always been strict in discipline, so he can only study at home, and cannot go to the vast world to play with the children. On this day, Lake was punished by his mother, and he was so angry that the toy Rubik's cube vented his anger. Unexpectedly, the Rubik's Cube that was hit actually emitted light, and became bigger and bigger, and finally turned into a tall and straight skyscraper. By accident, Lake broke into the Rubik's Cube Building, saw the fragile and beautiful Glass City, the Children's Kingdom ruled by children, and also experienced fierce wars in the Insect Kingdom. His adventures go up to the sky and into the earth, and surprises come and go, but how will he find his way home?
