Powerful Minister of the Great Song: I Extend the Dynasty's Life by 300 Years

When Xiao Yan is reborn, a tattered copy of The Exploitation of the Works of Nature takes shape in his sea of consciousness. It is neither paper nor silk, and only he can see or touch it. It cannot be seen from the outside. Only when he wills it can he turn a page, and each page grants him a later-era technique or military stratagem, such as gunpowder formulas, fortress designs, or cavalry formations. However, he can open only one page a day, and if he does not put what he reads into practice, he cannot open another page.

The volume is incomplete and can be restored only through “changes in the course of events.” In other words, new pages unlock only when he alters major turning points in history. Using the volume, Xiao Yan foresees the broad course of events and secretly lays his plans without giving himself away. The volume is silent and unseen, like a light shining only within his heart. Since only he knows of it, he conceals thunder in silence and the fate of the realm within his mind.
