Unscientific! Who Cultivates Immortality Like This?

Is this the world of cultivating immortals? Strange, very strange. Wei Feng felt that his trip to time travel was a bit redundant. Before the Qi training period, you have to temper your body and challenge the limits to create a spiritual fetus in order to feel the spiritual energy. Understandable. But... Who challenges the physical limit by staying up late, drinking, puffing... You even have to sleep upside down! It's unscientific! Who cultivates immortality like this? It's almost like breaking down your body and ascending to heaven! Tired of living? And... Did you get your identity wrong? The evil cultivator is actually an upright person? There is no intrigue. The so-called righteous monks take injections and take drugs every day! If you lack spiritual energy, you will be fined if you are reincarnated! Demonic monks are diligent and never take shortcuts. Is the monster clan the enemy of the whole world?
