Konoha Orphans: Started by swallowing Tsunade’s rations

He traveled to Konoha and became an orphan. He had no parents and no one to adopt him. His body was extremely weak and he had to be placed in an orphanage.

Danzo Shimura asserted that he would die young, but he grew up and even awakened the Wood Release Bloodline.

Danzo Shimura regretted his decision, but was unable to take it away because it was adopted by Tsunade and given the surname Senju.

But no one knows that he has a talent development system:

As long as you achieve various growth goals, you can unlock various talents and rewards.

Complete a breast milk intake and gain the immortal body.

Complete ten somersaults and obtain the Wood Release Bloodline.

Complete 100 long jumps to gain a natural spirit body.

Win 100 Ninja Games to gain incredible insight.

How can an orphan get breast milk? It seems that we can only ask Tsunade, she must have a way.
