A few days later, in the underground crack outside the undying city.
Looking from above, the underground crack looked like a huge Canyon. On both sides of the canyon were steep mountain walls and jagged rocks.
Some fluorescent stalagmites with a faint green light were hidden among the rocks, decorating the dark Canyon. There were tall underground fern plants growing in the canyon. From the cracks and hot springs in the canyon, a hot air with a sulfuric smell would occasionally spray out. Beside the canyon, there was a River of dark red lava slowly flowing.
There were also some cracks in the canyon, which were dozens of meters wide and even hundreds of meters wide. It was dark and endless, leading to an even deeper and bottomless underground.
The Mantis blade bugs crawled out of the cracks in the canyon and rushed to the surface.
