It felt as though it had reached a balance, any more would result in an explosion.
What's missing?
Without any usable Heavenly Materials and Earthly Treasures at hand, Xu Jin planned to abandon it.
After all, the power had increased, and now this Ink Jade Armor should be considered a top-grade Seven-Star Spiritual Treasure; its defensive power strengthened, with no resources wasted.
But just as he was about to give up, Xu Jin suddenly recalled the Wood Spirit he exchanged for previously.
"Why not give it a try?"
"It's only a hundred points; if it successfully upgrades, it would be a significant gain. An Eight-Star Spiritual Treasure, even a low-grade one, costs two thousand points."
"It might just lead me to a path of fortune."
Xu Jin convinced himself.
