Origin Convergence Formation?

Standing on the wall of the residence, Zhang Xuan frowned. A grade-7 formation?

This wasn't the largest residence within the entire royal palace, but it had the most formidable formation of all—a grade-7 formation.

A formation of that grade had already surpassed Hongyuan Empire's level.

It seems like that is the most important place in the royal palace. The Bodhi Saint Tree must be inside! A glint flashed through Zhang Xuan's eyes.

According to what Zhong Dingchun said, the Bodhi Saint Tree was the foundation to the royal family's power, so it must be very tightly-guarded. This residence met that requirement perfectly.

Whether it would be able to save Wei Ruyan or not, he would just have to enter and take a look for himself.

Zhang Xuan began studying the grade-7 formation with his Eye of Insight, but a moment later, he shook his head.
