Although the cowhide paper looks crumpled, it's actually due to the nature of the cowhide paper itself. The edges are not frayed, and they are delicately sewn with gold thread, indicating Kaier's usual care in preserving it.
But can cowhide paper truly be a treasure?
Angel glanced over.
If the cowhide paper contained an emotionally rich letter, it would be understandable, but there were hardly any words on the paper.
The paper only recorded a theorem formula.
Just one look and Angel knew this formula should be a variation of a fundamental spatial formula, a type of variant stemming from basic formulas that is quite common in the Wizards' Realm, sometimes even leading to the creation of an entire "new world." At this point, such variants are no longer called variants but become a new theorem.
This is essentially the concept of the knowledge tree.
