The Emperor of Heaven has ruled the three realms in the heaven for tens of millions of years, and he is lonely and alone. Due to the changes in the laws of heaven, he is able to get married in the heaven, and all the immortals and gods around him are in pairs.
The Emperor of Heaven naturally felt even more lonely. Just because of the great changes in the human world, the Heaven Realm kept pace with the times and added a three thousand world travel system, referred to as the "Travel Office".
Then he took a nine-year vacation with Taoist Hongjun, and the four emperors temporarily took over the heavenly duties. His body was sealed in the heaven, and the soul brought the No. 0 Machine of the time-traveling system to break into the gate of all realms alone.
