The summoning talisman itself is not ineffective.
The main issue is that these people don't know how to use it properly.
Collecting soul aura with the summoning talisman doesn't necessarily require personally killing monsters.
If there are monsters dying somewhere, you can take out the talisman, and it will automatically collect the soul aura. The stronger the monster, the more aura is collected. However, even so, collecting aura in the Spirit Realm is still quite slow.
After monsters die in the Spirit Realm, their souls are instantly released, leaving very thin aura. It's different in the real world; the soul remains for a long time, so collecting soul aura after returning to the real world is the correct way to use it.
Yes!
This thing is very useful!
It can be used alongside the Spirit Gathering Lotus!
In the real world, the Spirit Gathering Lotus can convert the spiritual energy inside monsters into absorbable spiritual qi.
