While she was communicating with Wei Na, Qian Jiyun had already paid 40 inner cores for both of them to spend two hours here.
"You paid so quickly?" An Jiuyue was shocked by his speed.
She had the urge to take back all the inner cores.
"Let's go in." Qian Jiyun held her hand and walked in.
It wasn't until she entered the Building of Years that An Jiuyue realized it wasn't as simple as she had imagined. After a few steps, a female attendant emerged and handed them each a sandglass.
An Jiuyue looked at the sandglass in her hand, confused, before looking at Qian Jiyun.
Qian Jiyun looked at her and explained patiently, "This is an hourglass. Every time you pick up a book, this hourglass will activate. When you return the book to the bookshelf and look for another, this hourglass will stop automatically."
