Letting out a breath, Li Su relaxed slightly.
Engraving the core had been a tiny bit harder than he had imagined. As expected, there was quite a gulf between thinking something through and putting it into practice.
Fortunately, his realm was high enough. As a Great Luo realm cultivator, not only could his thoughts transcend the shackles of time—even his actions could do the same.
Over the entire process, there had been twenty-four node errors. Of course, these had not been errors in his control, but differential errors caused by the incompatibility of the nodes themselves.
After all, what he was working on was not a standalone thousand-rune diagram, but a composite multi-rune diagram.
It had leaped directly from a thousand runes to three thousand. On top of that, he was not building from scratch, but designing a structure atop an already damaged foundation that could accommodate every problematic node.
The difficulty of this could practically be called hellish. If someone else had been doing it, even a certified alchemist with practical experience would have had a headache. It was far more difficult than an ordinary three-thousand-rune diagram.
Putting away his engraving pen, Li Su looked at it and said, "Give it a try. Check whether the core circuit is functioning properly, and see how it runs."
"Okay!"
He could sense the emotional turbulence in its voice. This was not surviving a catastrophe—it was being reborn from the brink of despair.
It could feel itself changing. It was not merely advancing; something deeper had been stirred. The runes this person had engraved into its core possessed a powerful growth sequence. Their ultimate potential was far from limited to merely three thousand runes.
The vessel itself was expanding.
Excited, it backed away slightly and began operating its core at full capacity.
