Naruto: Otsutsuki Beten

After traveling through time and being the descendants of Otsutsuki Yamei, Otsutsuki's original family members are withering away, and only Otsutsuki is scattered around the universe to plunder chakra. Otsutsuki Betsuten came to the system on the way. Unexpectedly, the system's mission was to dominate and transform the ninja world, so he could only come to the ninja world. First, he swallowed the body of Otsutsuki Yamei (completely absorbed it later). At this time, it was the second ninja war, and he took the three little Akatsuki to start the journey to the ninja world. The rewards of the system tend to focus on external items such as technology, and the strength of the protagonist depends on it. The protagonist has white eyes, magatama samsara eyes, and eyes with golden pupils with blue ripples (I haven't decided on the specific name yet, so I'll call them golden blue eyes for short). (The three types of eyes can be switched at will. The red Nine Magatama Rinne Sharingan on the forehead, and the Six Magatama Purple Rinne Sharingan in the eyes. In addition to the basic abilities of the Rinne Eye, the pupil technique is Budou Yuhun, which uses thunder and lightning to form a sword and can release lightning attacks; Izu can sell his life and Oya Biko. The Oya Biko can make people burst out with negative emotions. Izu can sell his life and suppress negative emotions. The god's soul can absorb ninjutsu, record it, and can be reused. Golden Blue Eyes: Kemei Wei Ya Yan Shu Zun, can instantly restore one's own or others' damaged body or disease, or give or take away vitality; Tian Chang Li Zun, attack with the embodiment of thoughts (restrictions apply, other pupil techniques or secret techniques will be revealed later) (The protagonist has the form of Jianyu Lei Zun, the appearance will be explained later) (The specific effects of the technique are explained in the text.)
