Physically, he might gain new powers or abilities as mentioned before. But there could also be negative effects. His body could reject the foreign blood, leading to internal pain and weakness.
It could be the result of Naruto's own inner demons. Maybe he discovers some dark secret about his past, like his parents being involved in something he can't accept. This self - realization could be so traumatic that it makes him cry blood as he struggles to come to terms with it.
Perhaps in this fanfiction, Naruto is in a situation where he has no other source of sustenance. He could be trapped in a desolate place with no food or water, and the blood becomes a last - resort option for survival. This would be a very dark and extreme take on the character, as it goes against his usual values.
In the fanfiction, it might be that Naruto's poison blood is a result of the Nine - Tails' influence. The Nine - Tails is a powerful and malevolent force. Its chakra could have interacted with Naruto's blood over time, gradually turning it poisonous. This would also add an interesting layer to their relationship. Naruto would not only have to deal with the power of the Nine - Tails but also the consequences of its influence on his blood, which could change how he approaches training and his relationship with the other villagers who might fear his now - poisonous blood.
Naruto might also use his blood control to enhance his physical abilities. For example, he could increase the oxygen - carrying capacity of his blood to boost his stamina. Or he could control the blood flow to his muscles to increase their strength momentarily. This would make him an even more formidable opponent in combat, and these applications would make for some really interesting scenarios in the fanfic.
