Watch the cutscene with Tsunade, and lets get going.
We can see a new menu here. Let's review it:
After preparing, press Leave Village and a map will be opened. There will be a red dot on the map which indicates your target. Go there and you will notice that on the way bandits will attack you. You need to defeat them all in order to continue.
After reaching to the burning village, you need to extinguish as much fire as possible to get further on. go straight through the corridor. Take the bandits out. Use shadow clones and they will show you which way to go. one of them will point on the house's wall. go there and press
. You will climb to the roof of that building. There's a water tank there. break it to cause squirt water all over the fire below.
Jump to where the first was. go into the building there and break down the door. Defeat all enemies. Inspect with Shadow Clones and go to the house where the clone is pointing. Destroy the water tank again. After you do that, go to the building where you broke down the door. then, turn left on the corridor. Take out the two bandits, and keep going with the help of the arrows. Fight one last time, and your job is complete.
Get back to the village. fight some bandits on your way if you want some exp (don't forget you don't have to go to the village immediately).
Once you are back, your health and chakra will be recovered. You'll notice a new option in the village menu.
Choose Hokage's Room and see the cutscene.
Congratulations! You have completed Chapter 1!
