Toaru Majutsu no Index: New Testament - Volume 3, Chapter 1: Which Side Will Deliver a Preemptive Strike? First_Contact.

An alien race invaded the Earth on June 6, 2128. At the midst of this war, many nations allied with the alien threat and the war nearly wiped out the rebelling humans of the planet. At the edge of mankind's survival, the United Nations Army launched its forces to eliminate the immediate stellar threats that loomed over Earth.

General Seeker Carlean, commander and leader of the mission, risked and gave his life to destroy the immediate stellar threat. The battle was won though Earth lay in ruins. Perhaps mankind will live to see a few years of peace before the alien threat returns to wipe out their existence.

At the immediate aftermath of the stellar battle, the fallen Seeker Carlean awakens and finds himself at aged 17, living the peaceful life he lived 16 years before he died.

So begins a new game in the battle for humanity's survival.

“The useless daughter of the Su Family, Su Ye, had gone crazy after being rejected by the Bo Corporation’s President!

On the first day, she touched her father’s head. “Nephew, I think this project I found is good. You can go auction for it tomorrow.”

The next day, she dug up the Su family’s ancestral grave with a shovel and muttered, “I remember that it was buried here?”

On the third day, she patted the shoulder of a certain clean freak CEO. “Little Bo, even if the marriage didn’t work out, we still have feelings for each other. I’ll give you a discount on this medicine, just give me six million.”

…

Su Ye, the most ambitious woman in the business world who had died 40 years ago, had coincidentally been reborn into the body of his grandniece.

Thus...

In the department of inheritance notarization, a large inheritance that had been shelved for 40 years was claimed.

The museum was surprised to see that a mysterious person had donated an astronomical antique that disappeared 40 years ago for free.

Hacker Alliance. An account that no one had been able to identify who was behind it for more than 40 years suddenly came online.

Mysterious Sister became popular online. K.O. Stone Gambling Master, Reincarnated God of Medicine, Big Sister Carrier, Taekwondo Grandmaster…

Tens of thousands of people wanted to pamper her, and the Su family’s doorstep was frequented by the seventy to eighty-year-old childhood friends of hers who were big shots of various fields.

A certain ex-fiancé was filled with jealousy. “Make it hot. Don’t affect my fiancée’s college entrance examination.”

Zhen Xiang might be late, but he would never be absent.

Bo Yunli never looked at her in his eye before marriage.

After the divorce, Bo Yunli suddenly asked, “Which project do you like? I’ll bid for it and give it to you.”

“These are the gold shovels and keys to the Bo family’s cemetery. Dig whichever you like.”

“That’s true. The prescription is priceless and six million RMB is too little. How about exchanging it for the position of the Bo Corporation’s Young Madam?”

After suffering from a heat stroke while working under the scorching heat of summer, Lu Zhou, a hardworking but poor university student, somehow becomes the owner of an advanced technological system. With the cheat given by the system, his university life changes overnight.

A Master’s degree? Easy.

PhD? Not a problem.

From a nobody, he quickly becomes a huge celebrity in the world of science. With the missions given by the system, he is on his way to winning a Nobel Prize.

“System, can points be exchanged for money?”

“No.”

“F**k, what use are you then!?”

“This system will make you the ultimate scholar, the kind that lords over all of humanity. What use will money be to you?”
