Video guide on how to destroy all the cannons in the chapter "Sanad's Resolve".

In this chapter, finding guns is not a problem. They are easily destroyed. The main thing is to be sure to shoot each one before destroying it. This is important for getting all the Kodama, since one of them is hidden behind a tower that must be broken with a shot. The main thing is not to forget to return to it later.
Each cannon has a barrel of gunpowder. All you have to do is throw a bomb at it or hit it with a weapon charged with fire - and the cannon is gone. One cannon along the way will be indestructible and one (in the branch into which you get through the hot spring, you will understand where it is) will be destroyed cunningly. She has a samurai sitting next to her, whom you need to kill quietly. This is necessary in order not to aggro the ghost of the mines nearby. After that, switch to a fire weapon and lure a mine ghost with a barrel on its back to the cannon. When he is nearby, hit him and he will explode. You should get the trophy with the destruction of the last cannon. If you reached the last altar before the boss and did not receive a trophy, go back and look for the missed cannon. The altar restores the barrel next to it if you accidentally break it somehow.
