Ji Taiping's Divine Sense swept past everyone in Kai Mountain City but could not find the entry jade slip, which suggested only two possibilities.
One possibility was that the person who found the entry jade slip had already fled.
But this possibility was almost nil, as no one could move that fast.
The remaining possibility was that it had been crushed and engraved into the Tao Foundation.
For the moment, he could not determine which possibility it was, as he couldn't possibly inspect the Dantian of every person in Kai Mountain City one by one.
Millions of people, it would exhaust him to death.
Moreover, if it had already been crushed and inscribed into the Tao Foundation, then even if he found it, it would be meaningless.
However...
Ji Taiping looked towards the Capital with a dark expression. When he flew over Kai Mountain City just now, he had faintly seen a giant within the city. There was only one giant in the entire Da Xia, and that was Zhao Yishi of the Caotian Sect.
