掂了掂手里两个沉甸甸的碎银袋子，费伦脸上泛起一丝笑意，脚步都快了三分。手里的活儿不算难，就是爬上爬下的功夫花了不少，钱倒是挣得实在。矿脉虽然不大，但挖出来的灵石品质不错，卖了个好价钱。他一边往家走，一边琢磨着，这钱是得赶紧换成灵石，不然放久了硌手也没用，而且碎银 Transformation into high-grade spirit stones is not convenient at all.

In the immortal world, resources are a big problem. They are limited in supply. This is something that Fei Lun knows very well. Relying solely on part-time jobs to accumulate spirit stones will take a long time. He has to think of something else, he has to think of some other way.

The idea of the demon beast mountain floated into his mind again.

The demon beast mountain is about a hundred miles east of their town. Inside the mountain, there are many types of demon beasts. Some low-level demon beasts, their hides, bones, and internal organs can all be sold for money. If you are lucky, you may even stumble upon some good materials. Of course, the mountain is very dangerous, not ordinary people can enter.

Fei Lun is an ordinary immortal cultivator, but he also needs to eat, and he also needs to practice cultivation.
