On the way here, President Anduin had explained the exact arrangements of this test to Chu Nan in detail.
Due to what Chu Nan had said in the previous trial, the Elder Council had decided after some discussion that this test aimed at whether he had secretly learned the Exterminating Heart Technique would be publicized to the entire Declan royal family.
If Chu Nan could not use facts to convince everyone in the royal family, he would still be suspected of secretly learning the Exterminating Heart Technique.
The content of the test was actually very simple. The Declan royal family would send the corresponding candidate to test Chu Nan. If Chu Nan could learn the other party's cultivation method through the battle as he had said, then the test would be successful. If not, it would be a failure. It meant that he had still learned the Exterminating Heart Technique from Princess Pamela.
