Chapter 124: A Streak of Crimson

"Brother, what exactly did you do to Shen Tianlang just now?"

As they walked on the street, Zhang Nala recalled the scene from before and couldn't help but ask curiously, "It didn't seem like you used much strength, yet Shen Tianlang fainted just like that. It's really miraculous!"

"It's nothing more than some internal kung fu techniques, nothing surprising," Erniu said with a slight smile, but he had an air of mystery about him.

"Internal kung fu? Brother, you're too amazing!" Zhang Nala, though half-understanding, felt an even greater admiration for Erniu. No wonder her elder brother was so skilled.

Erniu chuckled, but in reality, he hadn't told his sister Zhang Nala that the "internal kung fu" he mentioned using on Shen Tianlang was actually a secret technique from the Dragon God Formula, named "Reverse Yin Yang Technique."

The effect of this Reverse Yin Yang Technique was quite straightforward: the practitioner could turn women into men and men into women.
