บท 3808: The legendary heavenly book?

Although LAN Xinyu had a master who was a Grandmaster in array formations, she did not have much talent in array formations. She had been learning a few array formations for nearly a year, but she was still not very familiar with them. Now, she was actually able to integrate the array formations into her domain. If this was not enlightenment, what was it?

"World annihilation, slash!" Just as LAN Xinyu completed her domain, Meng Zheng slowly pulled out his long blade and slashed at the air.

This blade was so slow, yet so heavy. It was not as sharp as the blade wind, nor was it as imposing as a rainbow, but it was so heavy that it made people's breathing slow. It faintly released the power to cut the sky and destroy the world.
