It's impossible to produce minerals from a plant, which is why the crown prince needs such high-tech pickaxes to get the job done. But there's no way to get to the bottom of the pyramid without going through the underground tunnels, which are connected to the top of the tree by a huge "levitation array" . He wonders where he should go to find some life ores, but he can't figure out a way out of the tunnel. He asks if he could cut a piece of tree trunk to get some minerals out of it. The underground tunnels are connected by a series of doors, and the trees trunk is connected to these doors by a tunnel. If you go through these doors, you'll get minerals of higher quality, but if you go lower, you won't get as good a quality of minerals. The higher you go in the tunnel, the more difficult it is to find the minerals, so you have to go all the way up to the 25th level to find them. He's surprised to find a stone fire, but it's too big for him. He also finds a fish, which he gives to Luotianxing.
