I Really Don't Want to Become an Immortal

Ahaha, I, Chen Changsheng, am indeed the protagonist. I have the system in hand, and the time travel is closely behind me. I want to be the Nascent Soul Ancestor in the new world. As Chen Changsheng laughed, a fugitive Nascent Soul Ancestor was blasted into fireworks by an ion cannon. Chen Changsheng looked around at the accustomed humans and technologically advanced urban construction, and murmured to himself, "Where have I come from?" Good news: Chen Changsheng, a social beast in the 21st century, awakened to the compulsory immortality system and traveled through time. Bad news: We have traveled to a future world where technology is highly developed and immortal cultivators are at the bottom.
