[Genshin Impact] It Doesn't Matter, I'll Go Crazy

If [Contract] requires the stability of 'rock', then [Transaction] is like 'wind', which is everywhere. "The establishment of a contract must be accompanied by a transaction, but the formation of a transaction does not necessarily require a contract as a basis." "How can I see it?" "Whether material or spiritual, as long as [interaction] occurs, the transaction fact is established and cannot be changed." "Speak humanly." "It's mine if you grab it." Astar, the Demon God of Trading, is a Teyvat salesman who is proficient in human nature: I took your treasure and gave you a sweet flower in exchange. What? Are you saying the values ​​are unequal? Not willing to exchange? But the scale in my hand is already balanced. Oh, let me see, there is an extra weight here, the name is... [Your life], hehe. * The traveler read such a book at Xingqiu's home, which said: Astar, the Demon God of Flowing Wind, is a famous evil god. After the defeat of the Demon God War, the defeated Demon God fled Teyvat, went to the dark sea, and became an evil god. The Demon God of Flowing Wind is one of them. Unlike the silence of other evil gods, the shadow of Astar is always active in a corner of the continent of Teyvat. Astal's former territory is unknown, but in a certain folk custom in Liyue, the image of the wind god is not Barbatos, but a young girl, and its description is quite similar to the image in the legend of Astal. Is it possible to think that this area once worshiped Astal, the demon god of flowing wind? He seems to also be present in the Kingdom of Monsters in the Legend of the Seven Kingdoms, and Astal is also called the Lord of Monsters in Mondstadt's fairy tales. However, it remains to be verified whether the Qiuqiu people and slimes are smart enough to establish a country. At the same time, the shadow about Astal also stems from another well-known rumor. The authority of this demon god is [Trade], which is different from the [Contract] authority of the Rock Demon God Morax. [Trade] is more taboo-free, so it attracts many people with evil intentions. Among the many rumors about Astar that have been passed down for thousands of years, the evil ritual about the [Transaction] is one of the most prominent ones. Greedy people give everything they have for what they desire, including money, power, family, emotions, memories, etc., Which can all be replaced, and as long as the conditions are met, the ritual will give them what they want. However, this is often the beginning of tragedy. Be wary of evil spirits, this is the most sincere advice. ——"Research on the Demon God War in Teyvat - Partial Summary of Chapter 9" 1.

The name of the heroine's demon was originally "Astaroth", which comes from the 29th among the 72 demons, Astaroth (I thought I had found a very suitable name, but later I found out that the prototype of [Istaru] is Astaroth...) (Anyway, it fits quite well, so just use it as a variant, so it became Astar) Purpose: Witness the changes and loss of civilization
