Here is how you can barter and negotiate with Seigou in Irodori Festival Deed Part 3, the sub quest of Genshin Impact event Hues of the Violet Garden with Sara and Sayu.
Genshin Impact Actually has a Barter and Negotiation System
Genshin Impact is full of small minigames and gameplay changes, strengthening its position as a JRPG as Final Fantasy for example was reputed for doing this all the time, especially stating FF6. While it's rarely used inside quests, Genshin also has a barter and negotiation system, here's a refresher for how it works.
How Negotiation and Barter works
When a negotiation phase starts, you'll have a set amount of Mora and the opposing NPC will start with a specific mood, represented by hearts. You need to propose a certain amount of Mora and try to see if they'd accept the deal for it. If your price is too low, the NPC's mood will turn sour. That's all there is to it. This should be mainly a refresher for you, as if you have reached Inazuma in the first place then you must have experienced the negotiation system at least once in the Liyue Archon Quest with Zhongli and Childe.
How to negotiate with Seigou in Irodori Festival Deed Part 3, correct price
When I played through the quest, I first proposed 130,000 and then 147,580 Mora, but both prices were too low. I ended up going all up to 170,350 Mora for the deal to get accepted. So when you start the Irodori Festival Deed Part 3 Quest, start by going for a price lower than 170,000 Mora.
