The flames of war in two generations are witnessed by Xuanji; mountains and rivers weep with blood, but the love and affection will never be extinguished.
In Shanghai during the Republic of China, revolutionary general Jin Yunshen (Gu Hong) carried out the top-secret "Xuanji" mission and met Lin Shuying, the daughter of a banker. She was actually a hidden stake in "Spark" and was ordered to monitor her. In the financial game and the spy confrontation, love secretly arises. However, Lin Shuying was shocked to realize that the online "Zhulong" had rebelled and colluded with the foreign enemies of "Guixu" to set up a dead end. In order to save Jin Yunshen and keep the flame of revolution alive, she detonated explosives and died together with the enemy. She died on the bank of the Huangpu River. Although Jin Yunshen broke through, he was stigmatized as "treason" and went into exile. He only held the "Xuanji Core" pocket watch she left behind, and he regretted it for the rest of his life.
A hundred years of reincarnation, a technological battlefield. Jin Yunshen was reborn as Jin Heng, a top scientist, and presided over the national important "Xuanji Project". Aerospace engineer Lin Xi (Lin Shuying reborn) was involved in the project because of cracking abnormal data. A dusty "Xuanji Core" and fragments of past life memories set off a reunion across time and space. They discovered that "Guixu" was still there and was stealing cutting-edge technology. The old hatred of family and country has turned into the current mission of protection. The two teamed up with Guoan to break the situation with wisdom: Jin Heng understood the enemy's plan, and Lin Xi's skills shocked everyone. Finally shattered a century-old conspiracy and became an important weapon to protect the country.
When the smoke cleared, they used irrefutable evidence to wash away the stigma of Jin Yunshen and Lin Shuying, and let their loyal souls shine. The green blood of the past life blends with the starlight of this life. "Xuanji" is no longer just a token, but also a fire of faith that illuminates mountains and rivers and never goes out. They stand side by side, guarding this prosperous age that was bought with blood and fire.
