The first breath.
As Su Ming was shocked and caught in a daze due to the four Great Arts of Divine Source, they repeated themselves before his eyes. In that short span of a breath, they repeated themselves thousands of times.
As the first breath passed by, Su Ming realized that he was no longer Sui Chen Zi. He seemed to be able to see a faint layer of black smoke coming from the white-robed and white-haired Sui Chen Zi. There were one hundred thousand faces within that black smoke, and all of them belonged to Su Ming.
When the second breath arrived, the one hundred thousand faces formed by black smoke spread out from Sui Chen Zi's body. Once they gathered together behind him, Su Ming could feel that he now possessed a body, and he was no longer a lost soul in the world.
