As Ang gradually caught up with the academy's coursework, he began devoting himself fully to an in-depth study of two runes. After a period of experimentation and reflection, Ang finally deciphered the function of the first rune—Mass Contraction. This rune could cause an inscribed object's mass to contract, greatly reducing its weight. Although its effect resembled that of the traditional Weight Reduction Rune, Ang soon discovered that the Mass Contraction rune was far more complex.
The principle of the Weight Reduction Rune was to create a repulsive force that reduced weight, and such runes had long been widely used both inside and outside the academy. Mass Contraction, however, was far more mysterious. It showed no external force at work and caused no visible changes to the object. Through repeated tests and comparisons, Ang confirmed that its weight-reduction effect far surpassed that of the Weight Reduction Rune. In theory, mass contraction should have increased density, and increased density would usually be accompanied by greater weight. Yet under the rune's effect, the object became lighter instead. Ang realized that conventional physics could not explain this phenomenon. It was related to the supernatural power behind the rune.
Although he had not yet fully grasped all the rune's secrets, Ang was certain that it had immense practical value. Especially in the production of weapons and equipment, the Mass Contraction rune could greatly reduce an item's weight without sacrificing its strength or performance. Ang was thrilled by this and began considering how to apply it to Enchanted Weapons, creating lighter yet sharper weapons.
However, research into the second rune had hit a bottleneck. No matter how often Ang inscribed and tested it, the rune showed no response and no noticeable effect. This left Ang perplexed. Though he tried all manner of combinations and experimental methods,
