[Use the array flag to arrange the array, the array eye can be hidden, the array is very flexible, the array plate is dead, it's just a ready-made tool, take it out and use it, and collect it when it's used up, the center of the array is where the array plate is, once it is thrown out, and no one presides over the formation change in the center of the formation, if someone or a demon beast breaks through the heart of the formation, the array plate may have to change hands. 】

[But this is an attack array, I will be attacked when I take a step, how to find the heart of the formation? ] 】

[It's still the old way, the strength of the formation master is a known condition, this is the array plate made by herself, the highest is the first grade, the upper is not the second grade, and the shroud range of the first-grade array plate is also limited, but because you don't know your location, you have to find the boundary first. 】

[Well, find the boundary. Lu Xiaoman squatted on the ground again and groped, [Is it okay to throw stones? 】

[Yes, find a few more pieces and throw them out, there must be a gap between attacks and attacks, it can't be so dense that there is no place for it, this is not a talisman array for killing, that is an indiscriminate attack, this is not, I guess it may be used in hunting and fighting with the enemy, but now no one is presiding over the change in the center of the formation, so you have to find out this safe path yourself. 】

[I come, I come. 】

Lu Xiaoman lay on the ground like a toad and picked up all the stones within reach, regardless of size, and threw them out in turn in the four directions of southeast, south, northwest, and north.

As soon as the stone was thrown, the formation reacted, and five kinds of spells appeared in the four directions, but there were several safe paths between the attacks, and within the path was the safe place for one's own people to stand, and outside of it were traps for prey or enemies.

Lu Xiaoman saw the nearest trail to her and ran with her feet, the shortcomings of the short legs seriously prevented her from escaping, and when she was about to step into the trail, a sharp Gengjin qi chased behind her, and with a pop, Lu Xiaoman became the fairy whose face landed first, but fortunately, this time also allowed her to finally roll into the safe area.

Ye Zhou glanced at Lu Xiaoman's face and wagged his tail, [It's okay, the skin is traumatized, it's good to have a little injury, tomorrow's alchemy class, go to Fu Xi and cry. 】

Lu Xiaoman touched his torn face, got up and walked along the path to find the border.

In order to sue tomorrow, I must win this formation today.

The safety trail was crooked, Lu Xiaoman didn't know where she was spinning around, she walked with a sore back, and finally touched the border, and an invisible wall blocked her way.

It's easy to do with the border, the circle of the border is a safe path, because this is the angle where you don't have to worry about being attacked from behind, if there is prey or the enemy is trapped in the formation, it is safe to attack with your back to the border.

Lu Xiaoman took out a plant branch for refining tools from the ring and inserted it on the ground, took out a box of needles and threads, took a roll of thread and tied the thread to the branches, and then touched the invisible wall of the border with one hand, and put the thread with the other, and began a new round of trekking.

The array disk can be a variety of shapes, rectangle, square, diamond, pentagon, hexagonal, octagonal, no matter what the shape of the array disk, the excited formation is an equally proportional enlarged array disk, the position of the array disk is always in the center of the array, go to the center of the array, destroy the array disk can break out of the formation.

Lu Xiaoman didn't know what the shape of the array disk trapped in her was trapped, she had to rely on her own exploration, according to the simplest rectangle to imagine, there is a boundary and there is an angle formed on both sides, and if there is an angle, it can be marked to measure the length of each of the four sides, with length and width, you can use the Pythagorean theorem to calculate the diagonal length, and the position of one-half of the length is the center of the array, and the array disk is there.

After walking for a while, Lu Xiaoman touched the corner of the formation, made a mark and continued to walk, and after going around, Ye Zhou reminded that he had finished a circle and returned to the position of the cuttings.

How many lines were used in this circle, how long are the four sides of each side, and you can know if you take a ruler, it is indeed a rectangular array plate, and then it is all simple, and the rest is to calculate, how to break Qin Jingyuan's array last time, and how to break this array plate this time.
