Entering The Hidden Fen Clan
Lin Mu started to find the nodes of the Formation array and managed to do so in about two minutes. Once that was done, he found the linking runes that connected it to the lower layers of the array.
Since this was a formation array, there were multiple layers that worked together and if one wanted to stop it, they would need to deal with the layers that either functioned as the connective layer, or the layer that supplied the spirit Qi to the formation array.
This was the basic method of dismantling a formation array and was the two pronged approach that was used often. Either one removes the power supply, or the circuitry to stop it from working.
Of course, Lin Mu could go the direct and more crude route by using an attack to break the formation array. But they were here for an alliance with the Fen clan and not a war. Plus, Lin Mu didn't want to break the formation array either and only wanted to open a path for him and the other two to enter.
