Jumping Levels.

Shi Lang did not know about the movement around him and kept channeling spiritual energy through his body. The changes were quick, and his foundation was deepening with every second. The disciples around him were all paying attention to his changes. 

Shi Lang's skin was turning transparent, and his blood was turning golden. This was the second level of the immortal physique realm: Jade skin and golden blood. The people watched for an hour and gradually saw that the bones were turning golden too. Although the change was subtle, it was evident.

One of the disciples said, "Why are his golden bones looking so glassy?"

The man from earlier said, "You all probably do not understand. He is turning his jade bones into golden jade bones." 

The people were shocked and exclaimed, "Senior Brother Kang, are you kidding? Look at this kid. He is just stepping into his twenties, and his strength is not that big. How could he have survived this much pain?"
