With such a location, under the current peaceful environment of the Wenhua Divine Dynasty, trade and commerce are naturally flourishing.
Lu Changsheng arrived at the Sui State City, what was the first thing he did?
Of course, he went to the Academy library!
Maybe he could find some records about "patterns" in the Academy library in Sui City.
The Academy library is not accessible to ordinary people.
But money can grant access.
Lu Changsheng spent silver coins and smoothly entered the Academy library.
Inside, many academicians were flipping through materials.
The library housed tens of thousands of volumes, and Lu Changsheng had no idea which book contained the clues.
Therefore, he decided to flip through every single one.
Lu Changsheng picked up each book and quickly flipped through them.
His speed was so fast it couldn't be described as just skimming; his consciousness could roughly grasp the content with a quick scan.
But he still needed to open each book.
