Lu Yuru brainstorms.
She is a Heavenly Pride, she is not foolish.
With the unique "Wisdom Eye," combined with the changes in the treasure light on Yan Chuan, she can easily deduce some things with her swordsmanship to about seven or eight.
Then combine with the oddity of the 'Gathering Treasure Basin.'
Then combine with Yan Chuan's prior adamant refusal to exchange the 'Gathering Treasure Basin' with her for the clearly more beneficial 'Sun and Moon Colored Glaze Bottle' for cultivation.
Combine the above points.
Considering all together.
Lu Yuru has every reason to suspect—
"Yan Chuan!"
"Can enhance the rank of exotic treasures?!"
...
Lu Yuru's eyes widened, this shock is indeed extraordinary.
"The 'Gathering Treasure Basin' was a Fourth-Rank exotic treasure at the time of the court, but in Yan Chuan's hands, it became a Fifth-Rank exotic treasure."
