Inside the study, Jiang Hao held the Pure Jun Sword and tempered it with spiritual power. According to the Sword Sacrifice Technique, he needed to thoroughly refine the magical sword with his own spiritual power, turning substance into incorporeality before storing it in his Dantian. This process was generally very long.
Jiang Hao calculated that even if he diligently refined it every day, it would probably take around a year.
While Jiang Hao was refining it, he suddenly thought of something.
Since he could now use the sword casket to store the Pure Jun Sword in his Dantian, could he refine the Pure Jun Sword within his Dantian through the sword casket?
Once the thought arose, he could hardly restrain himself from trying it.
He summoned the sword casket and placed the Pure Jun Sword inside. After the Pure Jun Sword shrank with a whoosh and flew into the casket, Jiang Hao stored the sword casket in his Dantian.
He channeled spiritual power into the sword casket. Since he had already refined the casket into his magical treasure, his spiritual power flowed inside without the slightest obstruction. Then Jiang Hao sent his spiritual power into the Pure Jun Sword to see whether he could refine it.
Jiang Hao was immediately startled, then overjoyed. He discovered that refining it in this state was more than twice as fast as refining it while holding it in his hand.
Jiang Hao was so delighted he nearly jumped up.
He had accidentally discovered another use for the Universe Sword Casket, and it was an extremely practical one that could greatly shorten the refining time.
The Universe Sword Casket truly was a fine treasure!
As Jiang Hao continued pouring in spiritual power to refine it, his mind began turning again.
