In the century-old Dajing Dynasty, a "Two Ques Incident" stirred up the situation - the whole family of the Marquis of Jing'an was slaughtered, the regent and his family were sentenced to death, both houses were stigmatized as "treason", and the sunset of the imperial capital was dyed red with blood. Lu Zhaoye, the orphan of the general, survived by chance and entered the palace as a guard to find out the truth. However, in the turbulent palace, he met Jiang Linshen, the step-son of the regent. The two bear a blood feud. From being wary of each other to being forced to join forces, they explore step by step in the secret fights in the palace and the disputes in the rivers and lakes, uncovering the shocking conspiracy behind the two strange poisons of "heartless love" and "bone love".
From the secret letters in the cold palace to the night rain in the rivers and lakes, from the separation on the cliff to the confrontation in the court, they have gone through the test of life and death, and their emotions have been repeatedly pulled between hatred and trust. When the true identity of Emperor Bai Ting (Lu Ting, cousin of Lu Zhaoye) is exposed, and when the mastermind Jiang Chengfeng's ambition to collude with foreign races comes to light, personal grudges finally give way to the righteousness of the family and the country. Brothers recognize each other and close friends join hands to smash the conspiracy and clear up the injustice in the final battle in the imperial mausoleum. In the end, the mountains and rivers returned to the Qingming Dynasty. Lu Zhaoye and Jiang Linshen put aside their disputes over power and status and retired to the world together, leaving only the epic legend of "the mountains and rivers were shattered, which shocked their dreams, and the beacon fires were still burning in the sky".
Intention: the choice between personal grievances and the righteousness of the family and the country
