The inexplicable palpitations coming from the endless white clouds surprised Xu Tui, but he was also very vigilant. As he suppressed the fluctuations of the main planet of mind power, he carefully extended his mind power. At the same time, he prepared the Mountain Seal and his left eye.
The Mountain Seal could attack and defend. If a powerful enemy attacked, the black eye in his left eye could allow Xu Tui to instantly teleport and escape. He did this because he felt an inexplicable sense of fear. It was a form of danger.
This danger might be caused by the spying of an expert or the attention of his mind power. Therefore, Xu Tui was exceptionally careful at this moment.
It would have been fine if Xu Tui did not use the Mountain Seal. He had just used the Mountain Seal when the feeling that made his heart palpitate from the endless white clouds instantly increased exponentially.
