Although the parchment looked crumpled, that was simply the nature of parchment itself. Its edges were not frayed, and they had even been hemmed with exquisite gold thread. Clearly, Kael usually took great care to protect it.
But could parchment become a treasure?
Angel cast his gaze over it.
If the parchment bore an emotional letter, that would have been one thing. But it was not a letter; there was hardly any writing on it.
Only a single theorem formula was recorded on the parchment.
Angel took one look and knew that this formula was likely a variant form of some foundational spatial formula. Such variant forms based on established formulas were common in the Wizarding World. At times, they could even give rise to an entire "new world." At that point, the so-called variant form would no longer be called a variant form, but a new theorem.
This was, in fact, the concept of a knowledge tree.
Many new ideas, new fields, even new "frameworks," "branches," and "factions," slowly sprouted and grew from that initial seed of knowledge, spreading outward.
Likewise, beginning with a foundational formula, studying it and extending it continuously until a new formula was derived through variation—this was known as the branching effect.
"Is this a variant form you researched?" Angel pondered for a moment. "The Basil Dual-Phase Formula?"
Kael had originally been clutching the parchment in his hand with some despondency, his eyes dim as though lost in thought. Only when he heard Angel's voice did he raise his head.
Kael forced out a smile. "As expected of you, my lord. You saw at a glance that this was... a variation of the Basil Dual-Phase Formula."
As soon as he finished speaking, Kael felt a gust of hot air from behind. He turned around in
