When Lin Huang returned from the third assessment after resting for two days, his combat level had already upgraded to silver-level rank-3.
In those two days, he brought Tyrant along to kill silver-level monsters. His Life Power constantly increased, having nine of Life Power columns in all four duplicate Life Wheels overflow. However, he had only accumulated 200 columns in the ninth column of his actual Life Wheel. Lin Huang intentionally left it at this amount of Life Power, so that he would not accidentally get a Life Light Baptism from killing gold-level monsters.
The upgrade in Lin Huang's combat level resulted in the ability to summon four monsters. The Epic level cards - Bai, Tyrant, Charcoal and the clown had been automatically upgraded to gold-level rank-3 as well.
