This discovery made Li Shiming want to add a few more Lifebound Spiritual Treasures, but unfortunately, his standards were too high, and the Fourth-grade Refining Materials that caught his eye were extremely rare and precious.
With his nano-sized rune engraving technique, if the refining materials do not reach Fourth Grade Top Quality, they simply cannot withstand the presence of billions of runes.
Li Shiming now has three Lifebound Treasures; increasing performance for the IBMz15 is impossible. He has no plans for its enhancement, as the IBMz15 has been completely energized and is bound to his soul.
Each performance enhancement of the IBMz15 is due to his cultivation realm upgrade triggering soul enhancement, which in turn upgrades the IBMz15.
Just as when he advanced to Nascent Soul Middle Stage, his soul and spirit were greatly enhanced, leading to a performance increase in IBMz15. Of course, for IBMz15 to achieve maximum enhancement, his major realm advancement is required.
