Introduction
Modern young man Lin Yan accidentally acquired the system and the ability to travel through time. He can freely travel to any dynasty in China. He can only carry 3 modern items on each journey. He is bound by the mysterious "Repair System", and his core mission is to make up for those embarrassing regrets in history - from protecting the fate of the Qin Dynasty during the changes before the death of the First Emperor, to Wuzhang Yuan being Zhuge Liang's opportunity to continue the Northern Expedition, to Fengbo Pavilion rescuing Yue Fei and Yanyun Border to help Chai Rong complete his work.
Every item you carry needs to be carefully chosen: should you use modern epidemic prevention knowledge and saddles to save Huo Qubing's good years, use high-yield rice seeds to alleviate the famine after the Anshi Rebellion, or use improved agricultural tools to help China get rid of its weakness? On the way through time travel, he not only had to deal with the survival crisis in ancient times and avoid the inertial backlash of history, but also had to accurately rewrite regrets under limited conditions. From the Xiongguan of the Qin and Han Dynasties to the markets of the Tang and Song Dynasties, Lin Yan used modern wisdom and three "life-saving things" to write a different ending for those dusty feelings at each key node.
