Xin spoke to Ning Rongrong, who was practicing boxing in the nearby training ground. Although his voice was light, as if speaking to the air, it reached Ning Rongrong's ears.
Ning Rongrong's skin was bronze, and her toned, lean muscles gave her a sense of deterrence. The sharpness in her fists evoked an inexplicable sense of awe. When she walked up to Qian Renxue and the others, her skin had just returned to its normal color. She simply made a gesture of invitation:
"Two Junior Sisters, I am Senior Sister Ning Rongrong. You can call me Senior Sister or Senior Sister Rongrong. Follow me."
After returning from Slaughter City, this Senior Sister's personality had become increasingly reserved.
Initially, she didn't understand what Teacher had told her that night under the starry sky.
After returning to the academy, she sought advice from her father, Ning Fengzhi. Her father only taught her this one passage, which she benefited from for the rest of her life:
[Generous and composed, undisturbed by waves, Xin's countenance astonishes the world. He has likely seen hundreds of thousands of young girls startled by his youthful face. If you can behold Teacher's appearance and maintain self-control, not letting your emotions show, truly with the steadiness and dignity of a Senior Sister, you can stand out among Heart of Fire students and be favored by Teacher.]
…
[Ding~]
Just as Qian Renxue and Hu Liena followed Ning Rongrong to their accommodation, a System reward appeared in Xin's mind:
[Detecting Host has accepted Hu Liena as a Disciple, rewarding Host with a 0.1 level increase in spirit power, a 5% increase in the cultivation years of all spirit rings and Spirit Bones, and a 5% increase in unique skill proficiency — reaching Grandmaster Peak.]
[Extracting Heavenly Fox unique skill…]
After reviewing the unique skills he possessed and the number of students in the academy, Xin felt both joy and pressure.
Currently, the academy's students had reached twenty, including:
[Ning Rongrong, Xiao Wu, Zhu Zhuqing, Dugu Yan, Meng Yiran, Ye Lingling, Yao Zi, Mu Yunteng, Mu Yunzhu, Shui Bing'er, Shui Yue'er, Xue Wu, Qiu Ruoshui, Shen Liuyu, Gu Qingbo, Yu Hairou, Qian Renxue, Hu Liena, Bell, Xiao Chenyu.]
Xin had created a Spirit Master's path for these Disciples, allowing them to surpass their own limitations.
Similarly, they had brought Xin hundreds of unique skills and creations of varying quality, enabling Xin to Breakthrough the Super Douluo Realm within a few short years, becoming the youngest Titled Douluo and Super Douluo in Spirit Master's history.
Likewise, the more Disciples there were, the more effort Xin needed to invest.
