Oh, right, I forgot. You have always been alone, and never sought a cultivation partner, you might not know about the "Mandarin Duck Entangled Secret." Let me explain it to you.
Before the last Minor Era of Inversion of Heaven and Earth, there was a sect named the Mandarin Duck Sword Sect. The Sect Leader was a pair of deeply in love cultivators. Their swordsmanship was unparalleled, known as the "Mandarin Duck Double Unparalleled," and they established the Mandarin Duck Sword Sect, standing proudly in the world.
However, few people know that while their swordsmanship was strong, the true foundation of their standing was the "Mandarin Duck Entangled Secret."
This cultivation technique cannot be practiced alone; it requires dual cultivation of a man and a woman, Yin and Yang, and moreover, both parties must be deeply attracted to each other.
Coincidentally, Qingqing and Little Lou were of one mind and succeeded in cultivating this technique.
