Tang Moli became a vampire while studying abroad. She finally adapted to the "inhuman" life under the guidance of her "father", but fell into a rift in time and space and arrived in a strange dynasty. Tang Moli, who grew up under the red flag of socialism, could not accept the setting of sucking the blood of a living person, so she tried every means to sneak into the battlefield to drink the blood of the dead. Because of the kindness she received from a young border army general, she could only hug him for the first time when he was dying. She also had to fulfill her responsibilities as a "mother" and teach him how to be a "non-human".
Yin Mucheng was the prince of Daxuan and was sent to the border. Starting from a small soldier, he finally became a frontier general. Unexpectedly, during a war, he was betrayed and on the verge of death. When he woke up again, he became a "non-human" and achieved the "immortality" that many emperors dreamed of. In addition to facing the problems of being able to only suck blood and sparkle in the sun in the future, the girl in front of him who claims to be his "mother" is also a big trouble.
