Are there any bottlenecks in practice? Just travel through time. Qin Luffy, who possesses the Hongmeng Supreme Treasure Martial Spirit Space, travels through various worlds, looking for martial arts masters, absorbs morality, and subdues the dragon with the Eighteen Palms? Dugu Nine Swords? There is no martial arts or technique that you cannot learn unless you want to. From Zhongwu to Chaowu, he swept through all walks of life and achieved great success.
This feels a bit like Swordsman.
