Murim's Weakest Princess

By the time Researcher Ke finished gathering her books, Anji and her assistant were already sitting in the study, poring over the basics of General Relativity while snacking on things Aunt Wine had packed for them.

Eating her meal, the researcher listened closely. However, her frown deepened over time. In just a few hours, this child had enchanted her childhood friend. Assistant Hu barely exchanged more than pleasantries with everyone else after the death of their teacher. However, Anji was a strange one. Maybe it was the innocence of a child, but even Researcher Ke found herself wanting to get involved.

"When we were younger, Keke and I often spent summer nights stargazing and spotting comets. It is difficult to see them past the barrier. Hence, our shifu created a special telescope for us. However, we haven’t used it since we started this huge research project. If I were smarter, we might have found a method by now. It’s unfortunate, but I can’t answer your question. Only Keke would know how gravity is measured."

...

After speaking for such a long time in a long-winded manner, all Assistant Hu could say was sorry. Feeling frustrated by his incompetence, Researcher Ke slapped the chopsticks down on her bowl. Her meal was half finished, but it could wait for now. If anything, Researcher Ke’s patience hit rock bottom while listening to the wishy-washy explanation.

"How can you not understand how gravity is measured?" she barked, storming into the room. "It’s the basic calculation we use when identifying the movement of objects through space!"

Jumping when he heard the researcher, Assistant Hu dropped the lotus seed he was munching on. Anji also jumped visibly on her stool. However, she was more surprised than afraid. Didn’t Researcher Ke say she did not want to be disturbed? Why would she suddenly involve herself?

Walking up to Anji, Researcher Ke took a glance at the messy textbooks and clicked her tongue. While Assistant Hu picked out the correct books, he was not teaching Anji General Relativity in the right sequence. Who in the right mind would start the lesson with gravitational waves? It was like putting a cart in front of a horse. No wonder Anji did not understand anything!

"Gravity is absent in space," the researcher stated, shoving Assistant Hu out of the way and flipping to a different page of the book in front of Anji. "Do you know why?"

Recalling her notes and straightening up, Anji answered the researcher’s questions to the best of her ability. "Because there is nothing in space?"

The answer was half right. However, Anji missed another part of it. Hence, Researcher Ke decided to start with the general concept. The child had some understanding. Hence, it would be easier to continue from there instead of going back to the beginning.

"You’re half correct," pointed out. "However, the sun and the earth also exist in ’space’. How can there be nothing?"
