Seeing Tong Yunshu's look of surprise, Qin Yanyang smiled slightly and looked at Yang Fei.
She knew that Tong Yunshu would be amazed upon seeing her.
Yang Fei transmitted sound to Tong Yunshu, explaining the mysteries of the Extreme Fire Demon Pearl, making Tong Yunshu both astonished and delighted upon hearing it.
With this, if she wanted to return to Earth, she could have Yang Fei take her.
The most crucial aspect is that the Extreme Fire Demon Pearl has such magical effects, enabling Yang Fei to escape back to Earth in case of unexpected events, unless faced with a much more powerful enemy, otherwise, it would be hard for him to die.
In the following days, Yang Fei noticed that as Tong Yunshu's Realm broke through, her comprehension in talismans and formations also took a significant leap forward, with her distance in using Rune Tao instant teleportation reaching one and a half times that of Yang Fei's.
