The most eye-catching topics were those concerning cotton, coal, and the Northeast region, which attracted almost everyone's attention.
After some investigation, they finally understood the immense value of cotton and coal, and those powerful families who had not sent caravans to the Western Regions regretted it deeply.

Cao Song then put down his brush and, quite surprised, accepted the invitation from the steward.
"Haha~ This Yuan Feng actually thought of the same thing as me!"
Upon seeing that the handwriting on the invitation was from Yuan Feng, Cao Song couldn't help but burst into laughter.
