Luo Hong stood in front of Huangfeng Valley Mountain Gate. At this moment, he had to admit that he had traveled to 'Mortals'. After pushing glasses that no longer existed, Luo Hong said firmly: Like Han Laomo, he is a fourth-grade pseudo-spirit root, but he does not have a small bottle.

How many factors affect the speed of cultivation? How fast does Han Laomo run? When cultivating immortals in this world is an objective fact, science is cultivating immortals, and cultivating immortals is science!
