Apocalypse: After Being Reborn, I Stocked Up on All Supplies - Chapter 20 - Cash is King

What happens when a scientist from a futuristic world reincarnates in a World of Magic and Knights? An awesome MC is what happens! A scientist’s goal is to explore the secrets of the universe, and this is exactly what Leylin sets out to do when he is reincarnated. Dark, cold and calculating, he makes use of all his resources as he sets off on his adventures to meet his goal. Face? Who needs that… Hmmm… that guy seems too powerful for me to take on now… I better keep a low profile for now. You want me to help you? Sure… but what benefit can I get out of it? Nothing? Bye. Hmmm… that guy looks like he might cause me problems in the future. Should I let him off for now and let him grow into someone that can threaten me….. Nahhh. *kill*-

Alternative: Leylin is transported from an advanced technological era into a medieval world— except there’s magic. Equipped with “only” his quick wits and an A.I. chip fused to his soul, he sets out to become the most powerful magus the world has ever known. In a land divided into the Light and Dark Magi, the weak can either be cattle or disposable slaves. Only the strong can determine their lives, and only they have the luxury for virtue. Yet strength is only a tool for Leylin, like any other. His goal, in the end, is his own.

”When I tell you to proceed with Plan A, you can’t just ignore it and go with Plan B,” said the king.

”Sure”, she replied; she’ll just go to Plan C then! No biggie.

”If you were told to go eastwards, you can’t just ignore me and go in the opposite way,” the king added on.

”Yes,” she said while nodding. If she can’t go in the opposite way, North and south work fine too.

”You are NOT allowed to have affair with any other men!” the king then emphasized.

”Sure”. She replied. She never has to be the one having affair with the others. Others have it with her.

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?”

“Rishe Ilmgard Wertsner! I’m breaking off my engagement with you!”
“Okay, I understand”
“Huh.”

The Duke’s daughter, Rishe left the evening party without delay.

In fact, for Rishe, this engagement has been terminated for the seventh time. And that’s where her new life starts, having enjoyed the way of life of a pharmacist and a dressed up knight, she lost her life at the age of 20 and now has gone back to the scene where her engagement was broken off.

Normally, this could have broken Rishe’s heart, but her mentality now is strong.
Her past six lives have been busy and fulfilling, she wants to live longer this time around.
If possible, she wants to live a life of leisure and squander money….

To commence her 7th life, Rishe has set up such a diagonal goal.
However, in this life, she will be married to the Crown Prince of a militant nation, who killed her in her past life.

…….. It’s probably better. It doesn’t matter if it’s a former rival country. In her seventh lifetime, she’ll enjoy loafing off at a castle!!

Against all her determination, she inadvertently demonstrated the skills she had cultivated in her past lives and garnered attention as a brilliant Crown Princess.
