Because he had just tried it, he deeply sensed the presence contained within that plaque.
The Dragon Knights couldn't recognize it, so why could he? Because he had encountered a similar presence before!
Contained within that plaque was not the ability to amplify the ice element and fire elements. It was similar, but absolutely not that. It was clearly, Yin and Yang! The Two Qi of yin and Yang!
Yes, to truly unleash the power of that plaque, it's not the ice element and fire elements that are needed, but the Two Qi of yin and Yang.
This immediately reminded Lan Xuanyu of Tang Yuge's Yin Yang Chaos Bird. It was the only being he knew that could simultaneously possess the Two Qi of yin and Yang.
