Reversing History: Starting from the Desperate Situation in Anxi

Newbie, new book, first of all thank you for your support! I saw some book friends criticizing the fact that historical texts should not be systematic. I deeply agree with this and also give a brief explanation. First of all, we solemnly promise that the system will never interfere with the plot, let alone help with any tasks! Only after the protagonist makes positive feedback independently, a reversal point is provided so that the protagonist can exchange for a certain technology that can be achieved through existing technology in the current historical time and space! For example, making salt, or soap, etc.! Although these can be made under the current conditions, after all, the protagonist, as an ordinary person, generally does not understand these craftsmanship, so the system exchange may not be so abrupt! In addition, according to the plan, in addition to the Anxi chapter, there will be several historical stories that are difficult to resolve, and they will all be completed one by one through the system by traveling to the past! Once again, I hope to get your support so that I can have the opportunity to tell everyone the story in my heart! Thank you

Can historical texts be written without the system? I immediately didn't want to read them.
