Shocking.

Feng Tao stood at the podium, he took out a boulder from his space ring and placed it on the podium. He then motioned the first person to climb the podium to place his hands over the boulder and channel his spirit energy inside the boulder. 

The person nodded and placed his hand on the boulder. He channeled the spirit energy inside th boulder. The big boulder trembled a bit as it shone with dim golden light, a few runes formed in the void. Feng Tao gazed at the runes and with a nod, he said, "Bone age 14, the peak of body formation realm. Please stand on the right side of the podium for the further procession." 

The youngster in front of him bowed and skipped down the podium with an exciting smile on his face. After all, he had passed the first round. Following him, a lot of youngsters climbed up the stage and verified their bone age.
