Sometimes, a stupid idea was a good one. This was what the extraterritorial race did. Yuan Rong believed dagger's words because he was dagger. He believed that Zhao Hai was hiding underground. He split the Army and used earth-type spells to dig down.
Their method was honestly very stupid, but it was also the most effective method. Because teleportation arrays couldn't be used in the trash world, when Zhao Hai and the others entered the underground world, they didn't use the teleportation array. Instead, they used a spell to slowly enter the underground world.
