This is a story about exploring technology in a wizarding world.Probability, electromagnetic induction, nuclear physics and theory of relativity—all of this can be mastered through scientific exploration and learning.Richard had always thought so… until he transmigrates to a world similar to the Middle Ages and becomes a prince. In this world of wizard and magic, he embarks on a journey to explain magic with science. One day, a dragon takes him away.“This is not in line with aerodynamics? It does not satisfy the Kutta condition, Circulation Theory of Lift and Bernoulli's principle either? How can it fly? Is there a special power source in its body?” Richard could not help saying as he glances down at the huge dragon he was riding on. “Well, I need to research this.”“By the way, you said you kidnapped me to find a playmate for your daughter. That doesn't sound like a good reason, right?”“Roar!” the dragon hollers furiously and waves its wings, soaring into the sky.Will Richard be able to continue on his journey of exploration and unravel the mystery of the wizarding world?

In the past, there was a small cannon fodder who wholeheartedly dedicated herself to the medicinal path.

Only after dying once did she learned that even if she was brilliant, she could only be an insignificant side character used to emphasize the female lead’s limelight. Any relationship with the male lead and other supporting male characters would bring her bad luck.

When going out to collect some medicinal herbs in Qingfeng Valley, she kindly rescued a male side character. The man woke up and saw the female lead and became eternally grateful to her instead. He thought that the monster that hurt him was brought by the small cannon fodder so she was punished.

The cycle repeated and eventually everyone she saved blindly loved the righteous female lead. Ultimately she was killed by one of the men who was entangled with the female lead.

……

So after her rebirth, she began to firmly adhere to the principle of ‘pay me first, then I’ll cure you’.

Male cannon fodders who love the female lead, charge them triple fee!

Male side characters who ambiguously entangled with the female lead, charge them 10 times!

Male lead, the most important one, charged him 100 times!

She single heartedly insisted on using money to distance herself from those men and drew a clear boundary between them. But her ability was too high, that the male lead and side characters from all over the world always came to her for help…

She finally became the richest person in cultivation world!

When Jiang Cheng was told to return to a family that he never knew or had a relationship with, he had never expected to end up meeting a young girl, and eventually, her seemingly roguish brother Gu Fei, as a first encounter in the new city.
