In Inazuma's Genshin Impact, there are six easy tombs that can be entrusted blood-flowering, and get the achievement. They will never grow old.
Simple Tomb # 1
To find this tomb, you need to solve a riddle in the Snake's Head. It is a huge snake skull rock on Yashiori Island in Inazuma. There is a latticed gate inside that can be opened by solving a puzzle.
On the left and right above the teeth of the skull, two Electro fairies are flying - touch them, and follow them until you find yourself at the ceiling of the head. Once you do this, the gate in the Snake Head will open and you can slide down. Along the way, you can collect electrocule.
On the next floor, a gate again blocks the path. All you have to do is go around the corner and pull the lever on the wall. Jump back down to the next gate. Kill the enemy first and go to the switches at the gate. You must interact with them in the correct order to solve the puzzle.
