Space Door: One day, Toutou and Arya were playing a chessboard brought by Heaven-Kid. Toutou by accident opened a device that transformed the chessboard into a Space Door. Through this Space Door, they could become anything they wanted, going anywhere they wished. Toutou and Arya having been thrown into this fictional world fought with each other while playing out many different roles. According to the principal regulation of the Space-Time board, they would be locked within, unable to escape. Heaven Kid used his magic to awaken them teaching them the book Di-Zi-Gui. Finally, Toutou and Arya having learnt their wrongs, corrected their ways, averting the crisis. Heaven Kid: The book Di-Zi-Gui was written based on Confucius, a wisdom of ancient China. Di-Zi-Gui outlines the standards for being a good student and child. Confucius believed that moral principles, virtues, and discipline should be the very first lessons taught to a child, and that a child needs to practice them daily.
