Jiang Fengwu, Li Shiqing, and Li Shilian's reactions weren't much better, but it was the little fellow Li Chengsheng who calmly said, "Dad, let's start the test."
Li Zhirui let out a long breath, casually condensed his mana into a fine needle, and drew a drop of essence blood from Li Chengsheng's fingertip to drip onto the Spirit Measuring Ruler.
Hum——
Instantly, the Spirit Measuring Ruler released an immense Spirit Light, turning completely red and dazzlingly bright.
"Yang Spirit Root?!" Li Zhirui's face showed a hint of surprise, his son's talent was actually so outstanding! Not only did he have unique spiritual roots, but they were also Heavenly Spiritual Roots!
Joy filled the eyes of the three, Jiang Fengwu and others, as their hanging hearts finally settled back down.
"Dad, there's also a bit of white light at the tail end," said Li Chengshuo in his childish voice.
