Which novel protagonist could travel through different spaces to train his abilities and have the plot of the system to exchange items? (But this does not include the Dream Exchange System that I have already seen.)

😋I recommend the following novels to you, I hope you will like them: 1. "Picked up the Main God System by the Road": Wang Qiang, who had many twists and turns in his life, picked up a Main God System memory card by the road. From then on, he began to travel through different spaces to train his own abilities. 2. "The Buddhist Experience of Quick Wear": After the death of the female protagonist, she was accepted by the Experience Department and thrown into a small world to experience life. She became a Buddhist experiencer and experienced all kinds of wonderful experiences. 3. "The protagonist's Halo Crusher: The protagonist who has the ability to quickly traverse through different spaces to train his own abilities and become a variety of characters. I hope you like this fairy's recommendation. Muah ~😗
