The Urban Dao Child.
Yang Dao is an orphan. He does not speak much. He is so introverted that if not for his grades no one would have even known about him. One day it all changed. A red helicopter landed in front of him and a black-haired beauty walked up to him. She spoke in a joyful and emotional voice, "Young Master, this servant finally found you." ... Follow Yang Dao, a boy blessed by the heavens. A guy who was given four familiar spirits by the heavens. DISCLAIMER: THE COVER IMAGE DOES NOT BELONG TO ME.
Humming.
Yang Dao's humming surprised the reporter but she noticed the shock on Viktor's face. The old man suddenly started to laugh. He turned his head to a man standing a few pit stops away and yelled, "Sylvan, the humming is back."
His loud voice attracted the man and he had a strange expression on his face. He did not clearly hear what Viktor was saying. Suddenly a technician came and said something to the man. His strange expression turned into a shock. Soon, the pit crew turned on the secondary listening channel and they heard a humm sound being broadcasted by the commentators.
...
On the track, Yang Dao was humming as he drove. His humming was not useless and neither was it just for his entertainment. As he hummed in sync with the vehicle, he started to notice the slight time-lapse in his control. Even after Micro-control, he was not completely at the peak of his skills.
