The principle was simple. Qin Manjiang could see but not touch, while Xu Yi could touch but not see.
But when both of them touched the Jade Cicada at the same time, the rules of the two space-times would change. In short, someone from only one space-time could not take the Jade Cicada away: they either could not see it or could not touch it.
That was why Qin Manjiang and Xu Yi held the Jade Cicada together, as though holding hands, keeping it in a constant state of switching the rules.
Right now, Qin Manjiang's solution was also simple. Since this ghost was in the ancient world, he could see it, and it could not hurt him. Then couldn't he simply let go the instant before Xu Yi was attacked, leaving Xu Yi alone touching the Jade Cicada and switching him into a state where he could see but not touch?
But then the ghost would definitely turn to attack him. At that point, he could only time it right and catch the Jade Cicada again, since the change in state would make it impossible to hold. As long as they maintained this cycle at the same frequency, both of them could avoid the ghost's attacks entirely.
Qin Manjiang even had some more outrageous guesses...
"It's coming!" Xu Yi said then.
"Get ready."
"I'm letting go!"
"Okay!"
"Release!"
"Catch!"
On the way to the west wing, two people who could not see each other were locked in a bizarre contest with a Vengeful Ghost. They had no room for error.
Tossing and catching, the two ran toward the west wing.
Mei Sijun stood at the entrance to the east wing. He knew this place all too well.
[Southern Branch Troupe]. He had visited countless times since childhood.
