Urajimaru: "Megumi, don't you think Senior Lu went too far?"

Muzan: "Demons see him as if they've seen a demon."

Xiao Jie: "This is the first time I've ever seen someone chase after Hisoka and beat him up."

He was Minato Namikaze's classmate, but the class's quietest member. He had no particular skills, and his lazy chakra prevented him from learning any ninjutsu. If nothing unexpected happened, he would become cannon fodder on the battlefield.

But—he has a cheat code! His chakra increases by 0.5% every day, and now he has one-tenth of a chakra, so the future looks promising!

I'll just focus on wielding my sword; the rest is up to the chakra!

When the Ten-Tails was born, he carried an invincible chakra and slowly raised his sword—Do you also want to dance?

Under my chakra, all ninjutsu is just flashy nonsense.

Thanks for the invitation. I'm currently in Konoha, just started playing a villain, and my salary is calculated based on screen time. My name is Yagyu Masahiko, my profession is a ninja academy teacher, and my side job is playing a villain in the Naruto world. My job: to deliver a heavy blow to Naruto, collude with Orochimaru, and lead Danzo to overthrow the ninja world. As long as I play the villain well, any form of ninjutsu, secret techniques, bloodline limits, etc., is possible for my salary. My career goal: to be an outstanding villain who can survive until the end! But now there's a small problem—even though I'm the main villain, the successor to the darkness of the ninja world, Tsunade insists that I'm the Hokage! How can this continue? Urgent, waiting online!

[Peerless Tang Sect] [Refreshing Story] [Anti-Three] Ten thousand years after the Tang Sect was founded, the young Li Yan inherited the legacy of the Bright Dragon King, then picked up a Silver Dragon King along the way and returned home... As time went by, he realized something was amiss. Why are they looking at me strangely? My spirit is a dragon, not a succubus. Ultimately, Li Yan gave up and chose to play it down.

As everyone knows, the mainstream chakra attributes in the ninja world are wind, fire, water, earth, and lightning, with yin and yang being hidden attributes. There are only seven chakra attributes; this is common knowledge in the ninja world. Only a few know that there is an eighth, hidden, special attribute: the space-time attribute. This is a power that even the most overpowered can barely master! Having transmigrated to the Naruto world and entered the same generation as the perfect ninja, Minato Namikaze, Gojo Yoru initially intended to become stronger by any means necessary. However, after a period of palpitations, he discovered that he had refined a special chakra and awakened a space-time bloodline limit. From a hellish start to an incredibly favorable one, Gojo Yoru decided to show this bloodline-obsessed ninja world what it truly means to be a superior ninja.
