The underground passage was very deep! Ye Xiu estimated it to be over two hundred meters below the surface.
After descending into the passage, he was surprised to find that it was dozens of meters high and a hundred meters wide. The floor, walls, and tunnel ceiling were all exceptionally clean and smooth. It was clearly not the work of human hands; it must have been forcibly excavated using Earth System Totems and Formations.
I could use these underground and undersea passages to build a subway connecting all the islands of the Eternal Islands in the future. The thought suddenly occurred to him.
Then he asked the surrounding Mutated Beasts, "Who is the Beast King?"
Instantly, a wolf even taller than Pipi Pig ran over and prostrated itself before Ye Xiu.
"Take me to the other two exits on Biluo Island," Ye Xiu commanded, jumping onto the Wolf King's back.
