Li Jiancheng seemed to know that Ning Cheng would say this, he said with a smile, "I also know that to set up a teleportation array that directly spans across realms, probably not even in the Taiyi Realm can you find such an array grandmaster. My current thought is to first set up a teleportation array that teleports to the place closest to another realm, and then set up another array in that other realm. Once we have the strength, I will ask Brother Ning to set up an inter-realm teleportation array."
Ning Cheng instantly understood Li Jiancheng's intention, which was like two places being separated by a river in the middle. To connect these two places, those building the road could only construct two roads, one reaching up to this side of the river, and the other starting from the opposite bank. How to cross the river has nothing to do with his formation setting. Of course, when he had the capability, he would build a bridge over the river.
