The Powerful Minister of the Song Dynasty, I Will Extend the Life of the Song Dynasty for 300 Years

When the protagonist Xiao Yan was reborn, a broken volume of "Tiangong Kaiwu" was condensed in the sea of ​​consciousness. It was neither a book nor a silk, but it could only be seen and touched. This thing is not visible to the outside. You can only read one page with your mind. Every time you read a page, you will get a skill or military strategy from later generations - such as gunpowder ratio, city defense structure, cavalry formation changes, etc. However, you can only start one page per day, and if you do not practice it after reading it, you will not be able to start it again. This volume is incomplete and needs to be completed by "changes in current circumstances". That is, only by promoting changes in major historical nodes can new pages be unlocked. Xiao Yan relied on this to foresee the general trend and secretly devise opportunities without revealing any flaws. This scroll is silent and breathless, like the light of the heart shining alone, and it alone knows it, so it hides the thunder in silence and the mountains and rivers in the heart.
