I Am Cultivating Immortality Scientifically Among Mortals

Luo Hong stood in front of the mountain gate of Yellow Maple Valley. At this moment, he had to admit the fact that he had traveled to "Mortal". Pushing up his glasses that no longer existed, Luo Hong said categorically: "Like Old Demon Han, I have a fourth-grade pseudo-spiritual root, but I don't have a vial. It seems that the only way to go is scientific cultivation of immortality!" Why is there a bottleneck every three levels in the Qi Refining Stage? How to maximize the chance of foundation building? How many factors affect the speed of cultivation? How fast can Old Devil Han run? When cultivating immortality is an objective fact in this world, then science is cultivating immortality, and cultivating immortality is science!
