This tripod is a middle-grade Dao Artifact, categorized as a space-type Dao Artifact, capable of accommodating living people, containing a small world within. Of course, its space is definitely not as large as Shenxiao Sect's Profound Spirit Mirror, and the True Qi inside isn't as dense.
This pill cauldron is called the Heaven-Melting Tripod, with no defensive properties, no offensive properties. However, during alchemy, it is twice as effective, capable of absorbing Heaven and Earth True Qi. If you are refining a low-level elixir, you don't need to do it yourself; you just need to throw the required herbs inside, and the Heaven-Melting Tripod can refine the elixir on its own.
You ask how Chen Mo knows this; it's what the golden ancient book says.
The owner of the Heaven-Melting Tripod is called Daoist Rongtian, a member of the Jie Sect, and a strong practitioner in the Void Realm.
