Why did Sadako's father kill her?

There are two Zhen Zi, one is a bad Zhen Zi and the other is a good Zhen Zi. Bad Sadako's father is a sea monster, and good Sadako's father is Dr. Silver Bear. Dr. Xiong killed Sadako because her superpowers were terrible and she wanted to block her body in a dry well forever.

Naoko Waichuan, a female high school student, watched a video of unknown origin with her classmates. Seven days later, she and her classmates died one after another, which attracted the attention of female journalist Reiko Kobayakawa Asakawa (Matsushima Nanako) and she decided to investigate the truth of the incident. Asakawa learned that Tomoko had been hospitalized for watching a video before his death.

Introduction:

It turns out that the image on the curse video is not shot through the camera lens, but vividly reflected on the film through special photography technology. The ability to project the image you want onto the base film without using a camera lens originated from two real clairvoyant geniuses in Meiji period, namely, Imperial Thousand Tombs and Long Tail Yu Zi.

Born in Meiji 19, the Imperial Thousand Tombs are called Thousand Tombs with a Thousand Eyes in Japan. Because of her brother's induced hypnosis experiment, she found a gold ring that fell into the sea through perspective in the summer of Meiji 4 1 year. In the movie, the rumor of the imperial ship Thousand Tombs has also been adapted into Shizuko, a mountain village where you can talk to sea monsters.
