The stellarsky domain used star crystals as the currency. Star crystals contained elemental star power, and a standard star Crystal could be exchanged for fifty spirit stones. This was not very friendly to cultivators from other domains.
Luckily, Chen jingzhai had a lot of spirit stones, so he wasn't afraid.
Led by han Xianzhi, he came to the largest Chamber of Commerce in the city for the exchange. He exchanged a total of One Million Star crystals, and no one was allowed to exchange more than that without the Chamber of Commerce.
A living first grade star demon would cost three star crystals, and a second grade star demon would cost at least ten star crystals. Third grade star demons were basically impossible to find, and even if they were on sale, they would be very weak.
Other than the star demon, Chen jingzhai did not let go of any other treasures.
