A day passed.
Three days passed.
Many more days had passed by since William's disappearance and the Celestial Army's faces had started to get irritable. They had been on high alert for the past six days, and some of them even felt constipated because they were always on guard for William's sneak attack.
It was as if there was an itch inside their body that wouldn't go away no matter how hard they tried to scratch it. While all of this was happening, the Half-Elf that they had been looking for was snoring under the Earth after working hard for the past six days.
William was very tired. He knew that there's no way that he would win against an Army that numbered in the millions if he faced them head on. This was why he prepared a surprise for them, thousands of meters under their feet.
At the start, it was only him working alone, but after a day, Sha decided to join in on the fun and helped him clear the land beneath the earth.
