Traveling Back in Time to Change My Life, I Can Only Save My Mind.

I am a student of history. I cannot bear to see loyal ministers die unjustly through the ages, and I cannot see famous generals and talented people die young. In an accident, my soul traveled back to various historical nodes and became a nobody, a soldier, and an official. I tried my best to change the rise and fall of the dynasty and reverse the trend of history. But every time I come back and open the history books, everything is still the same, not changed at all. It turns out that the general trend of the world is irreversible and the trajectory of history is immutable. Since I can't change the world, I will only save people. Fusu, Han Xin, Yue Fei, Yu Qian, Yuan Chonghuan... I will make up for your regrets. I'll protect your lives. History can continue as usual, but you cannot die in vain. In this life, I only do one thing - Take the person away before the knife falls!
