I Got Stronger By Using Copper Coins Until I Am Invincible - Chapter 542 - I’m really a business genius

Lin Ziyin, modern day mechanical professor especially hired by the school, had the potential for great achievement in her field. However, due to family reasons, she could only treat her mechanical research and teaching as a secondary job, pouring all her energy into the farm and the food business before. Despite her low-key approach, she was unable to suppress her sister's rage, and a furious car crash sent her straight to ancient times.Indeed, she had excellent character, so why did the heavens send her to the sparsely populated Northern Land. Known as the death zone, those who were banished to this borderland would spend their lives and perish there. However, Lin Ziyin was quite satisfied with her own identity. Even if she had lost the protection of her parents, she still had the protection of her siblings and grandfather. Of course, she also had her younger brother and nephew at home who needed her protection. This abundance of familial love was enough to compensate for the hardships caused by poverty at home.Poverty, she wasn't afraid of, as she had experience in farming. With large swathes of uncultivated land, the Northern Land was practically custom-made for her. The heavy workload didn't matter either, she was proficient in designing all kinds of small tools. Whether it was the emperor's absurdity, not providing aid to the border king, or the shameless Tatars that would rob them frequently, none of these posed a problem for her. She could think of solutions for everything. It wasn't uncommon for the border king to tell everyone how lucky he was to have married such a wonderful queen!

This is the story of Kir, who has to thwart the will of Heaven, Hell, and his parents in order to survive, protect the people he loves, and achieve happiness.He just has to make it through life at a magical academy, avoid dying, and survive to find his birth mother, the lost Daughter of Heaven. Or be forced to take his place at the side of his father, a Duke of Hell bent on destroying the way things are.It's a lot to handle for a quiet, brooding angel boy.Fortunately, he has company. A succubus, a foxkin girl, and a half-angel boy to start. And Kir has his own secret: this isn't his first go at life.

She died in her prime as the Queen of Song.

After being reincarnated, she becomes a simple trainee.

Losing her former glory? It doesn’t matter—no one can compete with her voice as a beautiful singer.

Mocked by her lowly birth? It doesn’t matter—her true identity is enough to make the whole world tremble.

She owes huge debts? It doesn’t matter…

A powerful boss once whispered to her, “Your debt will disappear if you become my woman.”

But the proud her would reply, “I’m sorry. I would sell my art, but not myself.”

After choking to death on a watermelon, Rong Jiahui thought that she would enter the netherworld and be reincarnated.

But when she opened her eyes, she discovered, to her very horror, that she had returned twelve years into the past…

Looking at the beautiful and awkward “little brother” that would be conferred the title of Marshal in the future for outstanding military service, she almost let out a snort of laughter.

She firmly decided to hug the thigh of this little brother, and climb to the top of her life!

The plan was beautiful, but it had just one problem.

Why had this little brother… suddenly turned into…

A little sister…
