Chen Xuantian didn't realize at the time that the Princess, Imperial Relatives named Yu Zao.
The Emperor's Yu Zao refers to the silk rope with mixed colors, threaded with jade and decorated with jade, thus called Yu Zao. In plain words, it's the five-colored silk rope with pearls and jade suspended before and after the emperor's crown.
In a place like the Immortal Palace, someone using such a high-level name is surely not a benevolent soul. Seems like it would be wise to rethink and recalculate this matter later, but first, tuck the Sword Box into the sleeve.
Bu Shiren was also curiously asking,
"Why don't you open it and have a look?"
Chen Xuantian smiled,
"What's the big deal about looking at it? She said it's a treasure sword. The two I have here are quite sharp, enough to deal with you. Come! Fight!"
As Bu Shiren didn't have any more words to spend, he nodded and said,
"Alright, I'll learn from you!"
