Chang'an Treacherous Vein

Introduction In the 23rd year of Kaiyuan, on a rainy night in Yongchongfang, Chang'an, seven sections of bone bells hung from the beam, and half of the butterfly jade wept with blood. The palace attendant Shili Xinglu, who held a copper ruler, could detect the secret art of general supervision on the bones; the traveling doctor Helangu, who carried a broken needle, sensed the lingering resentment in the Yin veins. A bone bell early warning, a fragmented map, and a dragon-locking game across the Sui and Tang Dynasties brought two tit-for-tat people into the thousand-year-old treacherous vein beneath Chang'an. The Yin point is hidden in the 108th square, the real corpse is buried at the bottom of the turning Yang spring, the twin stars cut their lives to avoid disaster, and the machine soul merges into the formation to guard the pulse. When the false mastermind plots rebellion, An Lushan's soul mark secretly emerges, when the paradox of memory engulfs daily life, and the obsession with the dead turns into Yin Qi, they will eventually discover: Chang'an's lifeline is hidden in the balance of Yin and Yang; and the truth of guardianship is written in the contract between the living and the dead. When the bone bell rings again, is it the return of the resentful spirit or the return of the butterfly jade? A life-and-death situation, with Chang'an as the needle and life as the guide, is slowly unfolding on the Yin and Yang book.
