In this guide, you will come to know how to open the Secret Room Gate and how to get items and chests in Genshin Impact. Follow the steps in this guide to open up the gate.
At first, you will need to make your way to the location near Starglow Cavern, as shown on the map below.
After getting there, you will find a gravestone. After finding the gravestone, now you need the Cecilia Flowers; you can buy them from the flower shop in Mondstadt. You have to plant the flowers on a grave, and then you will get the first chest.
The next location is near the Wyrmrest Valley, as you can also see on the map below.
There will be a broken tower at this location. You have to head to the top of that tower, and you will get another chest.
The last one is on the small island near Snow-Covered Path, as shown in the map below.
After getting there, you will find some enemies, and you have to defeat them within a minute. Once you counter them, you will get another chest.
After getting everything from the chests, you have to make your way to the Starglow Cavern. Once you reach there, you need to go to the top of it, and you will have to glide towards the side, as shown in the image below.
Then you will find an entrance, go inside, and you will find a chest. And also, make sure to check the ancient caverns.
