The Fake System Cultivated a True Emperor

Yi Xiaoyao is a time traveler who came to this world of immortal cultivation. He has a system like everyone else, but his system seems a bit ordinary. The system's rewards do not include techniques or panacea, but only spiritual stones. Hundreds of years later, "Ding, congratulations to the host for entering the Nascent Soul Realm and a reward of 200,000 spirit stones." "It's only 200,000 spirit stones... It's of little use to me now. Forget it, it's better than nothing." System Yi casually stuffed the reward given by the system into the storage bag. "By the way, system, the rewards you have released recently are a bit low, and the rewards for this mission are not very good... Will you upgrade?" Hundreds of years passed... "Me, the Immortal Emperor? The strongest person in the world?" Yi Xiaoyao felt the power in his body, but he always felt that something was missing. By the way, it's the system. Since the Mahayana period, my system seems to have disappeared and has never given me any tasks. Although the reward is not worth mentioning to me, I still miss it a little. "Yes, I think you have heard it. In fact, there is no system at all. The system was pretended by me. I am also a time traveler, but I traveled earlier than you. When I picked you up, I saw that you are also a time traveler. I want to train you, but I have no experience in raising children, so I pretended to be a system and gave you some goals. As for those spiritual stones and rewards, I earned them by working until your Mahayana period. I never expected that the fake system would cultivate a true emperor!"
