In the chaotic times of the late Yuan Dynasty, dragons and snakes rose from the land. The great vitality is about to be exhausted, and the dragon veins are turbulent, causing the vitality of heaven and earth that has been dormant for hundreds of years to revive again. The world ushered in a prosperous era of martial arts, sects and rebels intertwined, martial arts and Tao strategy collided, and the change of dynasties came with the era of martial arts innovation.
Xu Tianye was originally the son of a minor official in the Yuan Dynasty. His family was wiped out overnight, and he was saddled with a blood feud. He obtained the secrets of the pre-Qin military strategists in the sea of blood on the Corpse Mountain, and since then he has embarked on a path to become a hegemon by killing and conquering, and using power and strategy as his weapon. Han Jiangyue, a fisherman by the Yangtze River, whose life experience is a mystery, was born with a Taoist fetus. By fate, he will receive the supreme inheritance of Taoism. He can measure the world with the sword in his hand and ask about immortality with a pure heart.
One is calm and tenacious, with a heart that is in danger of mountains and rivers; the other is free and uninhibited, with a mind as leisurely as flowing water. The two met by chance and became brothers in life and death. In this broken mountain and river, they were involved in the torrent of the times, from the rivers and lakes to the battlefield, from the mortal world to the secret realm. Together, they will face the hero's conspiracy, the invasion of the demon sect, the ancient secrets, and the destiny that hangs above all living beings.
This is the legend of two dragons standing side by side. This is a huge disaster related to the fate of the world and the ultimate martial arts. When the righteousness of brothers encounters important issues between kings and ministers, when personal paths collide with the fate of the people, can they join hands to open up a new era that belongs to them in this broken mountain and river?
