Siheyuan 1935, I Was Guarding the National Treasure in Peiping

A piece of jade pendant handed down from ancient times sent him back to Peiping in 1935. On New Year's Eve, Shen Nianzu opened a camphor wood box that had been dusty for sixty years in the courtyard where his grandfather died. There is no inheritance in it, only a suicide note, a jade pendant, and a ridiculous instruction—— "Wear it, go back to 1935, and tell my young self: Don't trust that Japanese." He thought it was a joke, but he woke up on the Tukang in the main room and fell into that turbulent era. The man he bumped into was a forty-year-old grandfather with a warm smile, not knowing what he was about to face. The Japanese businessman Ichiro Yamamoto came to the door. On the surface, he was talking about business, but in fact he came for the original copy of "Yongle Dadian". Baiyunguan Underground Palace, Yuan Dynasty culvert, Liu Bowen's Dragon Vein Eye, a national treasure that has been lost for six hundred years... A protection plan that spans time and space quietly unfolded in the cold winter of 1935. The Japanese want more than just a book; In Shen Nianzu's hands, he only had three days of traveling through time, a brain from modern times, and the trust that his grandfather risked his life for. "Hide the weapon in your body and wait for the time to move." This is no ordinary time travel. This is a man, with six hundred years of firepower, racing against an era. The secret war in the courtyard begins tonight.
