Genshin Impact: How to Solve Ryuuji Case in Heizou Hangout Long Sealed Mystery Quest

Most of the quests in Genshin Impact revolve around defeating enemies and killing bosses. However, there are some that involve a lot of investigation, dialogues, and conversations. One of them is the Ryuuji case which is part of the Long Sealed Mystery quest in Heizou’s Hangout Event.

In this guide, I’ll walk you through the steps you need to follow in order to successfully solve this quest.

How to Solve Ryuuji Case in Heizou Hangout Long Sealed Mystery Quest in Genshin Impact

In order to solve this quest, you first have to look for Owada and Uesugi. Talk to each of them regarding the investigation of the quest. Doing so will pop up a handful of long dialogues which you need to finish.

After you’re done talking to both of them, head toward the two bookshelves and make sure to read all of the contents. This is a very important step, so make sure you don’t miss it. Reading all notes will give you information that you will need to talk to Heizou. Only do so once you’ve read all 8 notes.

Then, talk to Heizou, and he will ask you if you have come to a conclusion. These are the answers you need to give in the exact order:

1. Yes, I did
2. Shiroyama’s Testament and Takatsukasa Isamu’s Message
3. Yes, I did
4. Yes, I did.
5. The Autopsy Report of Takatsukasa Isamu, Shiroyama’s Testament, and the Toxicology Report.
6. Why is the ‘’Research Log from the Office of Forensic Science’’ blank? Did someone tear out some pages?
7. Based on the ‘’Convictions’’ written by Kujou Sara for Ryuuji and Shiroyama, the two committed the same crime. Why are their punishments different?

As you can see, this is a pretty long-ass conversation, so you have to sit through all of those dialogues. At the same time, make sure you choose all of the correct answers above. There are times when you only have one option to choose, so just choose it.

Once you finish the conversation, you will then unlock the An Ideal Detective I Am achievement. Also, Heizou will point out that you need to change the location for the discussion. After that, the quest is then complete.
