This is really interesting.
When Joshua crossed over the deep dark tunnel that slanted down all the way into the pyramid, he found that he arrived at a gigantic metallic living hall. That was when he got the thought saying that it was really interesting.
A real world was really vast. The pleasure to explore here in this world was much more exciting and interesting than exploring the world in the game. It was additionally exciting to explore and discover this uncultivated world. Joshua could feel his heartbeat was accelerating involuntarily, just as he was battling.
To him, that was the best praise he could ever receive.
