Lin Yi smiled and nodded in agreement. The Tianxing path was indeed lucky. If the invisibility formation wasn't damaged, he wouldn't be able to find this place even after a hundred years of searching.
The level of the formation in front of them had also reached the standard of a level Seven formation, and it was a very rare technique. Just as Tianxing had said, it required two people who cultivated the creation battle technique to activate their true Qi at the same time in two directions to open the entrance.
"Brother Tian, don't you think it's a little strange? Why did that person need to set up such a formation when he was in seclusion to advance? He's alone, so is there a need for two creation battle technique users to join forces to enter?" Lin Yi walked back and forth a few steps, pinching his chin as he looked at Tian Xing.
