Ning Yujing was surprised because she understood that the contemplation diagram in the Heavenly Demon Nether Dragon Scroll was not merely a heirloom, but rather, it was analogous to a holy artifact made from the twenty-four ancient materials, incredibly durable.
The demon chart itself could superimpose the powers of all the contemplation diagrams and unleash a staggering force, which could send shivers down the world's spine!

After the demon lord ascended, no successor appeared. To truly control the demon chart, one could only showcase part of its power through the special secret technique of the Demonic Cult or by taming the spirit of the demon chart.
But how on earth did Han Ye manage to do that?
