Although the Demon Core was indeed very useful, what Chen Nuo wanted to know more was how she had thought to use the Demon Core as a gift.
The staff at Chaos Residence, apart from Tian Peng, really had no use for the Demon Core, not to mention Sun Wukong, who didn't need it either.
The Three Demons, although they were also demons, did not find the Demon Core very important either; after all, their ambition for cultivation was not that great, with the only eligible user being Tian Peng.
However, Tian Peng's whereabouts in the mortal world had always been well guarded by himself; it was either that Yang Chan knew Tian Peng needed the Demon Core for his cultivation or it was just serendipitous.
If Yang Chan had given the Demon Core because she knew of Tian Peng's whereabouts, Chen Nuo wondered how she had come to know, whether Yang Jian had told her or if she had discovered it herself, and whether the Heavenly Realm had any clues about Tian Peng's trail.
