Genshin Impact In Search of a Hidden Heart quest guide

With the release of Genshin Impact version 5.5, Travelers can finally explore the Great Volcano of Tollan, which has been visible since the addition of the Natlan region in version 5.0. After six months, HoYoverse finally introduced the volcano, and it is nothing short of impressive.

Hidden beneath the Great Volcano of Tollan is the ancient city of dragons, known as the Ancient Sacred Mountain. To enter the volcano, you must complete two quests: The Way Into the Mountain and Nahuatzin's Leap.

After entering the volcano, you will begin the Chronicler of the Crumbling City world quest series, which features 10 quests. In this guide, we will go through In Search of a Hidden Heart, a minor quest that is part of the Chronicler of the Crumbling City series in Genshin Impact.
