As for why She could recognize that Shi Hao is from the Stone Race.
Because of the bloodline.
The Stone Race's bloodline is special, especially for a plant life like Mu Yingchun. The aura that's extremely close to the essence of wood makes them particularly easy to connect with.
And the aura on this fellow named Shi Hao in front of her is even more intense than that of the master, which makes Mu Yingchun very fond of Shi Hao.
Hmm, if Chen Zhixing were here, he would realize that this little creature is fond of the aura of the newly regrown Longevity Bone on Shi Hao.
The Stone Race is special.
Because this race is suspected to inherit a bloodline far above Longevity, peculiar things like Longevity Bone or heavy pupils, different from the Celestial Profound Human Race, will grow in their bodies.
