Tsunade had actually been following Uchiha Yin and Uzumaki Kushina since they left school, and along the way, she had encountered several Root ninjas.
When she met these Root ninjas, Tsunade didn't hold back, letting one go to report to Danzo while dealing with the rest.
Of course, Tsunade didn't kill them, they were all from Konoha, and Tsunade wasn't that ruthless.
She just gave them a good scolding.
After dealing with the Root ninjas, Tsunade became the only one tailing them.
The Telescope Technique could only target a fixed location, and required the user to reapply the technique whenever they moved.
So Hiruzen Sarutobi had stopped monitoring Uchiha Yin and Uzumaki Kushina.
Hiruzen trusted Tsunade completely and had recalled the other ANBU.
Besides, as the Hokage, Hiruzen was busy with official duties and didn't have much time to monitor Uchiha Yin and Uzumaki Kushina.
So only Tsunade, an outsider, witnessed what happened.
And it was precisely because she saw this scene that Tsunade's opinion of Uchiha Yin changed.
The reason was simple: what she saw contradicted the information she had read.
Or perhaps it wasn't a contradiction, but a significant difference, the information was too 'superficial'.
Like Uchiha Yin's supposed bad personality.
In Tsunade's opinion, Uchiha Yin's personality wasn't bad, just extremely tsundere.
Otherwise, he wouldn't have helped Uzumaki Kushina deal with that incompetent genin.
But after defeating the genin, Uchiha Yin didn't accept Uzumaki Kushina's thanks like a normal person, instead acting awkwardly and telling her not to mind.
That's the definition of tsundere!
His bad personality was just a facade, his heart was warm.
No wonder, Uchiha Yin wasn't an important character, and the ANBU's information was likely superficial, so it might not be entirely accurate.
Tsunade found a reason for Uchiha Yin's supposed bad personality.
If Uchiha Yin knew what Tsunade was thinking, he'd probably laugh out loud.
The previous Uchiha Yin really did have a bad personality, but the current Uchiha Yin was a completely different person, so his personality had changed.
"His strength is among the best for a genin, maybe even at the chuunin level, otherwise he wouldn't have defeated that genin so easily."
"How can his strength be so different from the information? Has he been hiding his true abilities?"
Tsunade frowned, thinking.
The information stated that Uchiha Yin had low talent, but Tsunade clearly saw otherwise.
Although that genin was likely among the weakest, he was still a genin, not comparable to a 7-8 year old ninja academy student.
Yet Uchiha Yin defeated him effortlessly, without using his full strength.
This contradicted the information.
"Interesting, Uchiha Yin."
At this point, Tsunade became interested in Uchiha Yin.
Actually, when the system told her to become Uchiha Yin's wife, Tsunade had already become interested in him.
A system that could grant strength so easily wanted her to marry a stranger, which meant this stranger must be of great significance to the system.
That's what Tsunade thought, but the information about Uchiha Yin's bad behavior made her instinctively dislike him.
After all, no one wants to associate with someone with a bad personality, let alone marry them.
But now, seeing that the information was completely wrong, Tsunade naturally became interested in Uchiha Yin.
"Uchiha Yin, why does the system want me to become your wife? Why is the information so different from reality? I'm really curious."
Tsunade laughed heartily and followed them again.
