For even the artifact refining room that He Song uses nowadays, the situation inside is still better than this one.
First, the artifact refining furnace used by He Song was a mid-grade spiritual device refining furnace forged by his own hands.
Second, most of the devices He Song refines nowadays are already mid-grade spiritual devices.
Therefore, the various spirit mines placed in the artifact refining chamber are also mainly used for the refining of mid-grade spiritual devices.
Their value naturally exceeds that of the artifact refining room right now.
Aside from this,
The spirit devices that He Song left in his artifact refining room
Are not so destitute.
Though most of the spirit Qi in his artifact refining room consisted of low-grade spirit devices,
There were also some mid-grade spirit devices.
And the value of these spirit devices would probably far surpass those here.
