πI recommend the following novels to you. They are all science fiction novels similar to the Matrix: " An Unlimited Journey Begins from a Demon Hunter ". The protagonist of this novel was on a mission in different nightmare worlds. " Mecha Crisis: Starting from the Matrix." The protagonist of this novel also came from the Matrix world and faced the Mecha Crisis. Real World Simulation. The protagonist of the novel could experience different worlds through the simulator, including the Matrix. I hope you like my recommendation.π
