But he is an N card, and all his skills can only reach the power level of an N card, and can only be enhanced by krypton gold! As long as you spend money to become an SSR, you can recover your abilities and become a registered game player again! Looking at his mother who was still alive in front of him, Jiang Feng shouted excitedly, "Mom!" Snap—a slap on his head. Eighteen-year-old Jiang Ning said fiercely, "What do you call your n-card mother? Call it master! Who is your mother!" Ever since he knew that krypton gold could enhance his strength, Jiang Feng's DNA started to move. "Mom! Let's spend some money!" "Mom! The weather is nice today. Why don't you spend some money?"
