"Relax," on a flat area of land, Chen Heng had an amiable look on his face as he looked at the group of children in front of them and spoke softly.
"Just put your hand on it, no need to be nervous."
The children nodded, but looking at Chen Heng, they could not help but feel a bit nervous.
There were people in the surroundings maintaining order.
The children walked up onto the stone slabs.
As they went onto the stone slab, the formation on the stone slab was activated.
Faint light covered the surroundings and slowly spread out.
Looking at that light, Chen Heng gave a slight smile and said, "Very good, continue."
Hearing his encouragement, the children continued to slowly walk up.
Following this, the stone slab continued to light up, giving off different reactions.
Soon, these children had all been tested.
Chen Heng picked up pen and paper and wrote down the results from this experiment.
