Yun Ziliang's worries weren't without basis.
Nobody had seen how intense the backlash from Zhou Xuan's three tattoos could be. If the intensity was too low, it would merely result in being plagued by nightmares, achieving nothing substantial.
If the intensity was too high and relied on Gu Ling's own soul to repair the damage but failed to do so, things could end disastrously.
But Zhou Xuan had his own trump card.
He revealed his right hand and said to Yun Ziliang, "There's no need to worry about this. This hand can pull the tattoo out of the skin. If I keep a close eye on her and things go sideways, I can simply pull the tattoo out to stop the backlash."
"Your right hand, that miraculous?"
Yun Ziliang, though surprised, felt the plan was foolproof.
"With this backup, it's fine to use it on Gu Gexing."
"But I still feel there's something off about it."
"What feels off?" Yun Ziliang asked.
