Empress Reincarnation: My Master is the Philosopher Pluto

Jiang Ning transmigrated to the fantasy world and became an elder of the Supreme Solitary Sect. After taking in a good-for-nothing disciple, he received a strong acting card and started playing the 200,000-year-old Nether King.

...

My name is Beigong Qianxue. I’m a reincarnator. In my previous life, I was killed by my enemies and reincarnated from the upper realm to the lower realm.

"Before I reincarnated, I had already reached the Martial Monarch Realm. After I reincarnated, I wanted to return to the Upper Realm to take revenge. However, in order not to let others discover my secret, I concealed my talent and entered the Supreme Solitary Sect. I was accepted as a disciple by an extremely handsome master."

However, why did this master often say things that she, as a quasi-emperor, could not understand?

"Only when you experience the seventh level of loneliness can you become a true expert. Our world was born from this.”

"Beauty is only a momentary feeling. Reality is eternal, but reality is never beautiful!”

Other than these words that she could not understand, what the hell was the Holy Radiant Nebula that her master had taught her?
