The two complemented each other.
However, what exactly was the origin of this Immortal Furnace?
About this question, Zhang Jing had also explored it before, but unfortunately, no matter how much he pondered, he couldn't figure it out.
To this day, it was still shrouded in mist.
Although he claimed to have refined the Immortal Furnace, it seemed that a certain necessary condition was still missing, so he couldn't be considered to have completely refined it.
It was also for this reason that he wasn't even clear about the specific rank of the Three-Eared Bronze Immortal Furnace, only knowing that it must be high; otherwise, he wouldn't be able to craft even acquired Spiritual Treasures.
If he couldn't figure it out, then he simply wouldn't think about it anymore.
Zhang Jing's eyes flickered slightly.
Hold breath! Concentrate!
With a sweep of his large sleeve, the Bronze Immortal Furnace opened accordingly.
