Gu Sheng's figure had not yet moved forward when he was struck by an invisible force.
He instantly flew backward, crashing heavily into a nearby tree.
"Senior Nangong!"
Gu Sheng called out with some effort.
Nangong Zheng's expression grew serious.
He was no stranger to the strength of this Demon King.
If he continued to heal Ji Ziyue, he might not be able to fend off the Peacock King's attacks.
Left with no choice, Nangong Zheng had to stop the healing.
"Ziyue, your injuries are mostly fine now. You'll need to train diligently from now on."
Nangong Zheng advised.
"Understood, thank you, Senior Nangong."
Ji Ziyue nodded and replied.
Seeing Nangong Zheng's unwavering care for Ji Ziyue, the Peacock King couldn't help but ask, "Brother Nangong, what is this about? Why such concern for the Ji family?"
"Nothing special. Just a promise."
As he spoke, Nangong Zheng stood up and brushed the dust off his clothes.
"A promise? What kind of promise?"
