Ye Mo found that after he set up the spirit gathering formation, the seal indeed was suppressed a lot more. He rejoiced and threw out all sorts of formation flags, suppressing the seal.
15 minutes later, Ye Mo and everyone else found that the rumbling sound grew quieter until it was almost unable to be heard.
That seal seemed still a little wobbly. Ye Mo looked at the ring on the stage and hardened his heart, putting an immortal crystal on it.
After that, the seal immediately quietened down. The formation around the stage seemed to be exerting great power. All the spirit chi rushed over to empower the formation.
"Ye Mo, is that stage a seal?" Tang Mengrao asked.
Ye Mo nodded. "This is indeed a seal, a level 10 seal too. Although I can't set up a level 10 formation, I can repair it a little."
