Shi Mu let out a soft sigh, and the expression in his eyes calmed.
The Hundred-Thousand Volcanoes was an extremely dangerous place. So, it was too dangerous to cross it. But, it wasn't an impossible task either.
There was a large city to the west of the Hundred-Thousand Volcanoes. It was similar to the size of the Red Flame city. It was called Fire Prison City. It was connected with the Red Flame City by a large-scale transmission magic spell. One could be directly transmitted to the Fire Prison City through this transmission spell.
Obviously, the people of the Fire Prison City could also be directly transmitted to the Red Flame City.
The location of these two cities — Red Flame City and Fire Prison City was – was very special. They happened to be located on the boundary line between the Demon race and the Barbarian race.
