Zhang Yi can take a closer look and see that this elder seemed to have an ability similar to his technique of ignoring restrictions and had an intermediate understanding of the laws of time and supreme understanding of the laws of space.
He was a very talented elder of this sect who was assigned to protect elder Su Lian and the other elders who were taking longer also wanted to protect elder Su Lian who was very important to the sect.
This elder was at the peak of the emperor's realm and was already using the phoenix dignity technique to come to help elder Su Lian more quickly, yet Zhang Yi's technique using the supreme understanding of the laws of time was not so easy to break into.
