The group of divine emperors walked up to a gate that had a simple title on it "Ying Yang Valley" and as they push the gate open as a gusting wind lightly fluttered as they saw a thriving forest with majestic tall trees interwoven with many primal beasts large and small that roam this valley and many would not be able to tell that this was the fear Ying Yang valley.
However, the divine emperors were not pleased because they now realized that they now have two big problems to deal with.
One of the problems was that they realized that they have underestimated how many heaven beasts would be in the valley because the other problem was that it was larger than originally thought making going to the center of the Ying Yang valley far harder than originally thought.
Right now they only had one option and that is to run straight down the through the valley to the middle where Ying and Yang intersect but it would be way shorter by about 10 times.
The original plan was to go through the left side of the valley as the Heavenly Ice Yin phoenix was weaker than the Yang God Dragon so they could slowly fight them off as they went through the Heavenly Yin Field to the center of the valley.
However, they could only scrap that as it was 10 god paces and 1 immortal pace when they originally though the valley to be 5 god paces as that was the size of the city and they thought it surrounds the valley, now that they know they can throw out resisting the Heavenly Yin Field and fending off the Heavenly Ice Yin phoenix because they will die halfway there!
1 God Pace = 1 trillion miles
1 Immortal Pace = 1 billion miles
