I Have Been Cultivating Immortality for a Billion Years, but You Tell Me That I Am Just Reborn?

Chen Xinghe traveled through time and space to a wild and ancient era. And the sign-in practice system has been awakened. Sign-in day after day can obtain cultivation level, as well as some rare treasures and magical secrets. Because on the first day he traveled through time, he was almost eaten by a terrifying monster. From then on, he firmly established the code of obscene development. From then on, he signed in and practiced day after day. When Chen Xinghe walked out of the retreat a billion years later and wanted to take a look at this new world, he was sluggish. Looking at the high-rise buildings and the busy traffic, Chen Xinghe suddenly became excited. "Get out of the system! I signed in for a billion years to cultivate immortality, but you actually told me that I was just reborn on earth a billion years ago?"
