Crystal Marrow is a very important character breakthrough material in Genshin Impact game, especially when cultivating Aloy and Sayu, it needs to be collected in large quantities. This issue will share some of the most efficient routes to collect Crystal Marrow, hoping to help you!

[Brief analysis of Crystal Marrow ]
Locations: Crystal Marrow is a Local Specialty of the Inazuma region and can only be collected in the Inazuma area. There are no special requirements for collection, just collect in the wild.
Refresh time: Crystal Marrows are refreshed once every 48 hours, so they can only be collected once every two days.
Suggestions for running maps: It is recommended to take Gorou and Kazuha, which can make the collection efficiency greatly improved, in addition, you can also add the double Anemo combination to the team, and carry a good amount of food and items that can reduce stamina consumption.
Function: The Crystal Marrows are mainly used as breakthrough materials for the character upgrade of Gorou and Kazuha. A single character needs 168 breakthrough materials to reach level 90, so the material demand is great. Secondly, in the world quest [Three Thousand Miles of Hope], 12 Crystal Marrows need to be given to the little boy Chouji 3 times, so a total of 36 Crystal Marrows need to be prepared.

[Collection route]
Route 1- Tatarasuna [13]
It is recommended to start from the upper anchor point, use the Anemo character skill to fly to the platform on the left, pick up two on the platform, and then go to the area where the Crystal Marrows are concentrated as shown in the picture. The collection efficiency of this point is very high, and it is relatively simple to collect.

Route 2- Serpent's Head [20]
The Crystal Marrows in Serpent's Head are quite dense, but some places are more secretive, such as on and inside the serpent's head, which requires careful searching. It is recommended to start from the anchor point at the bottom of the diagram in two ways and collect along the marks shown.

Route 3- Jakotsu Mine [12]
This point is generally recommended to start from the middle anchor point and walk along the route to the seaside. It should be noted that there are four Crystal Marrows in the sea on the right, so you have to jump into the sea from the position shown in the picture to collect them. There is also 1 Crystal Marrow in the Jakotsu Mine, but it is not cost-effective and can be abandoned. If there is an urgent need, you can start from the bottom anchor point to explore.

Route 4- Musoujin Gorge[8]
The Crystal Marrows at this point are generally on the surface of the serpent's bone, and parts of them are located between the two segments and above the bone. This point is relatively simple, go up in the direction shown in the picture, and you can see them along the way.

Route 5- Fort Fujitou[13]
It is suggested to come from the Statue of The Seven, collect along the route and go to the river. The Crystal Marrows at this point are basically on the surface of the bone.

[Summary]
In general, the collection of Crystal Marrows is relatively easy. They are all in one large area, and the collection points of each route are relatively concentrated, they are very dense and can be searched very quickly. Except that there is only one in the Jakotsu Mine, which is not very cost-effective to collect, other points should not be missed. Collect as many as possible. It should be noted that if you want to go to the area with the densest Crystal Marrows, you must first complete the side quest of Tatarasuna, because only in this way can you move on. When running maps, if conditions permit, we suggest you take Gorou and Kazuha to improve efficiency. In addition, if Crystal Marrows are not enough, you can also go to the world of friends and rub some! Well, the above is the collection route of Crystal Marrows. I hope it can help you collect more efficiently!![]()
