Lu Zhou had long lost interest after looking at the Nine Twist and Turn Formation. He could see the end of it with just a glance; it was not challenging at all. He guessed it was just a small ordinary formation that Lu Tiantong left behind. However, just as he was about to leave, he felt something was amiss when he saw the young cultivators being sent flying.
Just a moment ago, the cultivators were still very relaxed. However, the fluctuation of the formation was slightly abnormal just for a brief second, which was unlike an ordinary formation.
Lu Zhou was quite familiar with formations. Based on his experience and intuition, he decided to take a look.
Bang! Bang! Bang! Bang! Bang!
The force of the formation increased. Many cultivators were flung out before they were even halfway in. The invisible force had undoubtedly grown stronger. Even some of the cultivators who made it to the finish line earlier were sent flying out before they were even halfway in.
