Looking around in the ring I saw that a lot of the items are not useable but I did find three things one was a sort of metal which had a strange aura around it. The second thing was a gem and last was a book that said sage art at the cover. Tatsu tried to input chakra and even some of his blood but nothing happens so he put it away.
Looking at the book Tatsu curiously opened the book, which he saw that it was a manual on how to get sage mode and it was the dragon sage mode unlike Naruto's sage mode which came from the toads. Reading through it he found out that if you want to start learning you had to get a dragon chakra seed that would be produced after a dragon died. Knowing that he can't learn sage mode for the time being he put it away and left the secret realm.
After getting back he quickly headed to his hideout and locked himself in his training room. He took out the Hashirama cells and mito cells and started to fuse them with his body which normally would not work because their cells are to powerful but it was to easy for Tatsus dragon body. It quickly devoured it and integrated into the body which made Tatsu have a wonderful feeling of vitality from both of the cells. One of the cells comes from the ninja god and the second comes from one of the strongest Uzumakis in the whole world.
After digesting the cells didn't he feel himself becoming stronger that much, the only difference was that he got more vitality. He didn't become disappointed because the main reason he wanted them was to get their bloodline from them so he could clone them into his clan.
After Tatsu devoured the cells he spent the next week just relaxing and started to think about things he didn't notice. The questions were, how did the Uchiha get massacred if I controlled Danzo and why did Uchiha Itachi still do the same thing as in the anime. He had to investigate that when he comes back to Konoha.
As Tatsu was relaxing and thinking he was that one of his ninjas came and said: master we have collected a thousand orphans from the age 4 to 10.
Tatsu replied: good job let's go and meet them. Walking the the main arena he saw that the kids were nervous and looked around in confusion. Seeing me come in they were a little scared and stared at me. I looked at the them said : I know that you are confused but this for the best, you will have a life better then before were you are appreciated and you will have a home, I want you to stand in a line and come one by one to me, is that understood!
The kids were intimidated by me but they whispered yea sir and started to form a line and started to come to me.
