The Martial Saint rose to power starting as a substitute bridegroom.

Li Yuan transmigrated to a martial arts world, his consciousness containing a page from an ancient book. "Holding the Heavenly Book of Evolution: Your sweat is the ink on this page; your perseverance is the path of evolution. Action will lead to success, and doing will surely bring achievement." Martial arts, once mastered, will inevitably lead to success, with no bottlenecks to overcome. However, he soon discovered that this "heaven rewards diligence" was ridiculously powerful. One unit of effort yields tenfold rewards! Yet, before he could even unleash his full potential, his biological parents had already devised a plan: to send him as a substitute for their genius younger brother in a marriage alliance with the impoverished Zhou family. "A marriage alliance is fine, but money is required." He initially thought it was a bottomless pit, but upon facing his stunningly beautiful and gentle wife… Li Yuan smiled. From then on, Li Yuan's life took off, flourishing ever more. A gentle breeze stirs the water, creating ripples on the surface. When he finally ascended to the Martial Saint realm, looking down upon all living beings, his genius younger brother knelt at his feet: "Brother, please, help me!" His biological parents wept bitterly: "Yuan'er, we were blind back then..." And beside him, the "impoverished" daughter had already become famous throughout the land. "My man is the Martial Saint who will suppress all in this world."
