Ethan Cross was a politician serving as the Secretary of the Department of Energy in the United States of America. He was also an engineer and a scientist prior to his position, to which he was hailed as a “King of Technology” as he was able to invent revolutionary technologies one after the other.But his life was cut short when the vehicle he was in was rammed by a truck from the side, and immediately after, he awakened in the body of a royal prince, Bruno de Elysea, who was a complete opposite of Ethan in terms of knowledge and capability.One thing he noticed is that in this new world, everything was so backward. Technology and politics. He desired to change them but by doing so, caught the eyes of those who opposed it.

After transmigrating from the apocalypse to ancient times, Gu Yundong barely had time to catch her breath when she realized she was in the midst of a journey to escape famine.

To make matters worse, her entire family had been expelled from the group fleeing the famine by her grandparents while others watched on coldly. With her father missing, her mother feeble-minded, and her starved younger sibling, Gu Yundong, who had barely caught her breath, only felt a major headache oncoming.

With no other choice, she rolled up her sleeves and got to work. She engaged in business, opened a shop, and acquired fertile land. Gu Yundong thrived in her daily life.

If it weren't for the people around her eyeing her as a potential wife, she could conquer heaven itself.
