Toaru Majutsu no Index - Volume 6, Chapter 2: After School. Break_Time.

When they first met, Tang Wan sighed, “The fifth young master of the Jiang family is just as the rumors said. He’s celibate, aloof, prideful, and is a man to be revered. Unfortunately, he’s so smart that he no longer has any will to live, which made him sickly, and he’s going to die soon…Later on, the fifth young master brought her into his room. When she came out, everyone stared at her in shock.Why was she crying?……Later on, it was said that the fifth young master returned after he recovered from his illness, and he brought a girl back.She appeared pure and harmless, but underneath that harmless appearance, she was actually a spitfire that offended quite a number of people.But the fifth young master just said, “I brought her back, so I’ll let her do whatever she wants. If… anything happens, I’ll take responsibility.”His best friend gave him a reminder. “You’re going to be responsible for someone from the Tang family?”“Since she came back with me, she’s mine. She’s just a young girl and is spoilt. I have to take responsibility.”After Tang Wan married into the Jiang family, she only had one mission. She must give birth to his children before he died!Meanwhile, the fifth young master was puzzled. “You’re a gentle and shy girl during the day, so why are you so different during the night?”Tang Wan thought. ‘I have to make every second count. He won’t be able to live long.’After she gave birth to his son and he became one year old, Tang Wan was prepared to become a widow.However…‘Why isn’t he dead yet?’Much later, the fifth master of the Jiang family asked her, “I heard that you’ve been looking for my death every day. Do you want to kill me by sucking me dry?”

The moment Kazuma arrived in the world of Jujutsu Kaisen, a cursed spirit knocked on his door, making him panic.Fortunately, he awakened the mission selection system.[Mission Option 1: Look into Gojo Satoru's eyes for ten seconds.Reward: Mangekyo Sharingan][Mission Option 2: Change Mei Mei's hairstyle to twin ponytails and have an in-depth communication with her~Reward: Tsukuyomi!]During the Shibuya Incident, Sukuna went crazy.Chibaku Tensei, Infinite Tsukuyomi, Susanoo...Yuji: “I thought that Gojo-sensei was already invincible. I didn't expect Kazuma to be even stronger than him.”Since he had arrived in this world, Kazuma vowed to make a happy ending.Gojo becoming Go/jo? That won't happen in his presence.Yuki, Nanami, Mai, Junpei...?He's going to save all of them.***This is just a translation. All credit goes to the original writers.Raw: 咒回：人生选择，开局万花筒！

The past life Ji Anran: “Geng Yan, let’s get back together.”

Geng Yan, who was dumped: “I refuse. You have powers anyway, and you can live well without me.”

After rebirth, the weak chicken Ji Anran: “Geng Yan, let’s get back together.”

The dumped Geng Yan: “I refuse.”

Ji Anran, lying dead: “I have no power, you don’t care about me, just let me get cold1.”

Geng Yan: “… …” The unsuccessful Geng Yan can only take away the weak chicken, one cannot put sand on the wall2 Ji Anran.

Later… what about the ordinary person without the strength to truss a chicken?! Who’s the guy in the day?

This novel is also known as Lady Is a Dragon

Five years ago, she left an egg and said, “This is the son I gave birth to you. When he grows up, it’s my return date.” He thought she was joking, but the son broke out of the egg a few months later. She looks like a baby, but there are two shiny, cute and cute little dragon horns on her head, but she has no return date.

*

Later, she disappeared for five years, and he also went crazy for five years, until Xiaolongzai brought back a woman, and he sobered up on the spot… But Xiaolongzai said: “Father, although you don’t have a wife, you will soon have a daughter-in-law. She saved me, and I want to make a promise to her!”

*

Since then, the father and son have fallen into open and secret struggles for favor.

“Your Excellency, Ms. Si’s medical skills have amazed the world, and big shots from all walks of life are fighting to spoil her. Your hero is useless to save the beauty…”

Mo Yinhe suddenly fell to the ground, coughing profusely: “Quick, call her to save me!”

“Your Excellency, the seven rivals who were tortured to the point of death by you are all Miss Si’s own brothers, and they want to take Miss Si back to inherit the throne…”

Mo Yinhe announced his abdication on the spot, and dragged his son to live on the street: “Son, from now on Dad can only follow you to your wife.”

The little dragon cub shook the shiny, cute little dragon horns on the top of his head: “Father, I have already contacted you with a nursing home, so that you can spend your old age safely~”
