Rule 1: You have to save people, starting from the time of Qin Shihuang, in order, and you cannot skip a dynasty.
Rule 2: The historical finale? Don't even think about changing it! You can save someone, but you want to be the savior? There is no way!
Rule 3: Good work is rewarded – how many more days will you stay? Bring more modern gadgets? Look at your performance!
College student Chen Yanxiu found a bronze lump in his grandfather's shabby attic. He thought it was an antique, but it turned out to be a deceptive "History Didi Beating Machine"! From then on, his summer vacation completely went astray:
Qin Dynasty: Having just escaped the knife of burning books and entrapping Confucians, we have to figure out how to save a "tech geek" who is about to be beheaded without making Ying Zheng suspicious... (Rating: A, reward: Junior pretending to be dead skill?)
Yashan of the Southern Song Dynasty: One hundred thousand soldiers and civilians jumped into the sea, and I could only hold back one scribe... (The rules are cold: saving one is the limit! I burst into tears!)
From the initial attempt to commit suicide, to being crushed by the torrent of history and doubting his life, through dozens of time travels, Chen Yanxiu danced on the tightrope: Save Yue Fei? The only thing we can do is to protect his youth from losing his fortune; see Han Xin fall? We can only grab the remaining manuscripts of his Art of War! The system score was cold and the wheels of history rolled over him mercilessly. What he saved was just a grain of sand in the torrent...
Until the last time the coordinates were locked: 1937, Shanghai, Sihang Warehouse! Under heavy artillery fire, he saw the figure jumping down loaded with grenades - his great-grandfather, Chen Shusheng!
"Rules? Reward? Go home?" He roared and rushed towards the hail of bullets, "I won't go back! I will guard this history with my life!"
