In your very first contract you will have a tutorial on how to use swords, horses and bows. When it tells you to use the Bowmen, do not take control of them. Instead, use the Swordsmen to fight the groups of people. After fighting for about a minute you should gain a level. You can do this as long as desired to better your men, making the beginning of the game easier. You can switch to the Horsemen to also increase their levels. When you feel you have their levels high enough, switch to the Bowmen to finish the tutorial.
This cheat is pretty simple, sometimes in the game you will see a deer running in your battles and if you walk into it it will fill your bladestorm bar (like musou bar in dynasty warriors) quite quickly and will keep re-filling for as long as you are touching it
