The Rock Kingdom World Artifact Cleaner is a cleaner that can clean artifacts. It is needed when we complete the troublesome research report task. Many players cannot find the location of this item, so they are unable to complete the task smoothly. Below, I will share the specific location of the cleaner to help everyone find it and complete the task. Players who have been unable to find it, please check below.

First, we need to go to the wild and find Senior James, and talk to him. From the conversation, we learn that his research report requires studying artifacts, but he has accidentally lost his artifact cleaner and cannot continue the research, thus needing our help.

After agreeing to help him, do not go too far. The information tells us that the cleaner was lost near James, not too far from him. You can directly head towards the round stone with a window, walk around to the back of the round stone, where you will find a patch of grass as shown in the picture below.

Crouch down and search in the grass. If you don't find it on the first try, you can search multiple times. The cleaner is hidden in this patch of grass. After searching several times and successfully finding it, return to James and talk to him. He will ask if you have found the cleaner.

Click yes, submit the cleaner you found, and he will thank you and give you some rewards. This completes the task. The overall process is quite simple; the only challenge is that although the cleaner is not hidden far away, it is rather concealed in the grass, making it hard to spot.

Above is the guide for the Rock Kingdom World Artifact Cleaner task. This task is not difficult; it's simply about helping James find an item. If you couldn't find it before, following the location provided above should help you find the cleaner, complete the task, and receive the corresponding reward.
