Two-Line Cultivation: My Sister Ordered a Technology Tree for Me on Earth

[Relaxation + Imagination]/[Hard-core dual-line cultivation of immortality]/[The mastermind behind the sister and brother]/[When scientific methodology breaks into the world of immortality]/[My golden finger is the almighty sister who is online 24 hours a day]/[Multiple female protagonists] Xu You, the author of "Fighting on the Street", turned into cannon fodder who couldn't survive more than three chapters of his book. Fortunately, he remembered all the plots, techniques, treasures... And the secrets of the heroines. Just when he was about to seize the opportunity and make a fortune quietly, he discovered that his portable earphones could actually connect to his real sister across borders. As a result, the most outrageous "immortal cultivation support group" in history was established. "Sister, help me check quickly. How can I optimize the spiritual circuit of the golden elixir stage to comply with the laws of thermodynamics?" "Xiao You, with the spiritual stone you sent me, I made a new energy battery and the company went public." Xu You relies on "spoilers" and "scientific plug-ins" to make a living in another world. My sister relied on "spiritual technology" to quietly build a huge business and spiritual empire in modern times. When the elder sister of the Xianmen takes off her disguise, when the demon princess breaks into life, when the power of the modern country begins to pay attention to the "abnormality"... Only then did Xu You realize that what they had changed was more than just the fate of the two worlds.
