"Hu…"

In the midnight, in the dormitory of Huaxia university campus, Yun Che suddenly sprang up from the bed, his chest heaving violently in his thin pajama and his bare chest covered with fine thin sweat. As if a drowning man suddenly got air, he gulped greedily for fresh air.

"Where am I…"

The school dormitory?

Welcome to all Young Military Rarities on Flying Lines.

Without knowing how long it had passed, Yun Che gradually calmed down. What fell into Yun Che's eyes was neither a dim research room nor a lifeless eschatological scene. Through the bright moonlight, the bunks, gray walls, shoes and socks on the floor were faintly visible. Yun Che was very familiar with this picture, which was his dormitory before the eschatological period.

Mobile phone!

At that time Yun Che suddenly remembered his phone. Following the memory, he stretched out his hand and pulled out the mobile phone that should be put on the inside of the pillow. He clicked on the screen and on it displayed the date, February 15, 20XX.

In half a month, doomsday would come.

In other words, he didn't know why he went back to the days before doomsday.

"Ha ha!"

Silly sitting on the bed and being dazed, Yun Che suddenly fell down. In the last days of the world, he had experienced four years of human sentiment changes, finding his sister having got killed and his brother changed into a zombie. He even encountered the betrayal of brother-in-law and the so-called lover at the same time. Killed under the rubble of the institute, he just returned to four years ago. Did god see his misfortune and specially give him a chance to start over?

The blindfolded hand slowly moved away and the dark eyes looked especially bright in the dark night. Since he had returned to the day before the last days, his fate was not at the mercy of God.

The outstretched hand suddenly clenched into a fist. Yun said, "This time, I would rather owe the world and never let the world owe me!"

Under such kind of circumstances, he was doomed to be unable to continue sleeping. Yun Che got up, took a cold shower and changed into a clean suit. He felt completely sober now.

Yun Che thought he must be prepared. The first was to ensure the safety of his sister and brother. But he could not tell them the doomsday was coming; otherwise they would panic. He could only cheat them to stay in the dormitory at home, or to be with him together. This could not be implemented for the time being; he had to wait for two days before doomsday.

Then he had to consider the storage of goods and materials. Before doomsday, the storage of goods and materials could only be bought with money. His parents died young. The elder sister left school early to earn money to support him and his twin brother Yun Cheng. Four years ago, although the elder sister married a so-called rich and powerful family, no one in the family respected them three. The elder sister's money was barely enough to pay the tuition fees for him and Yun Cheng. Therefore, he and Yun Cheng worked hard to earn living expenses in the school. He didn't have much money in hand. However, thanks to advanced network technology, it was very convenient to borrow money on the network. Yun Che borrowed nearly 200,000 yuan from various platforms. The identity of college students was also quite useful this time. The doomsday would come in half a month anyway and he didn't need to repay the money.

200,000 yuan was enough for him to prepare the materials in the early stage. As for the materials in the later stage, he would slowly collect them after the coming of doomsday. The most troublesome thing now was the storage of materials. He owned thunder superfunction and space superfunction. He tried just now, realizing he still had thunder superfunction there, but lost space superfunction. Therefore, materials could only be stored in a hidden warehouse first.

Of course, he did not forget the most important thing, revenge! Yun Che was not a saint and he would revenge those who owed him in the past life. Of course, the first one was Han Mingzhe who taught in this school.

As far as he knew, Han Mingzhe's family was not very rich and had no background, but he had become an associate professor at the university since he was no more than 30 years old. In China where seniority was valued, Yun Che did not believe at all that there was nothing fishy about human affairs. He just felt silly that he didn't realize it before. There were actually loopholes everywhere.

"Without seniority, one could only rely on the background, and Han Mingzhe could rely on…"

Yun Che touched his chin and lost in thought. His mind kept filtering the top leaders of the school. He was quite familiar with the top leaders of the school because he often helped professors clean the office. In the end, he noticed a person, Yang Biqin. She was the president of Huaxia University. She had a beautiful name but was not beautiful herself. She was 40 years old, divorced and single.

Han Mingzhe had neither money nor power, but he was handsome, learned and physically attractive, too. Han had treated him very well in the last four years in order to survive. Therefore, it was not strange that he would hook up with Yang Biqin.

Then, before doomsday, why not give him a delicious appetizer first!

In the dim light of night, Yun Che's thin face was covered with naked strange smile. Returning from the doomsday, he was destined to make turbulent waves.
