Firstly, go down the cliff and talk to a guy down there. Then, jump across to the bridge and start killing. Find a Carp Scale, on one side of the bridge. Then go inside the water to kill two more Treasure Carps for their Scales. The reason you need these scales is for trading purposes.
There is a guy around there, who exchanges Carp Scales for other items you may need. Just get the withered red gourd for the moment. Next, go to the other side of the bridge for the Estate Path Idol.
Now, this next area is full of enemies, so give your best to kill everyone. Continue killing including the two bandits outside the small building inside of which is the Shinobi Axe of the Monkey.
Next, go to the dilapidated temple. Go to the sculptor and equip your new shinobi tools: Loaded Axe and Flame Vent.
You’ll probably need to go back to Ashina outskirts to make some more gold just in case. Then travel back to the Estate Path in Hirata. It doesn’t hurt to rekill those guys as long as they give you more XP.
Kill, kill and kill until you make your way up to the Shinobi Hunter. Now, this one is a bit difficult, because after you get hit by him you have to heal yourself. So, take care!
Tip: take some time learning how to upgrade your skills and how to use the collected items properly
Then, go to the last area. Kill everything you find and pick up some items. Finally, go to the burning place. His injured father is inside.
Jump, jump, jump and then go down the cliffs. This way you can go earlier towards one of the bosses.
From here you can pop up the Homeward idol. Head back to the temple and put on your Mist Raven.
