This rapid cultivation method indeed has drawbacks, as it often leads to an unstable foundation. Once this happens, achieving breakthroughs to Enter the Path becomes an unattainable dream. Especially with the Smelting Furnace Method, the danger is extreme. If the foundation is unstable, not only does it hinder entering the path, but it might also lead to one's demise, completely obliterating oneself.
Yet, the various races in stellar space have accumulated Sun Blaze cultivators over countless years. Although it was difficult to advance previously, the foundation is solid due to this difficulty. Under these circumstances, rapid cultivation doesn't pose much problem.
Take Gu Sheng for example; despite his outstanding talent and being dubbed the brightest rising star in the Yellow Dragon World, under normal cultivation speed, he would at most be in the Sun Blaze Early Stage.
