"This is the identity token of the little sister, senior brother, you can get this thing to enter the first layer of the Mu family's library pavilion, although the first layer only has a variety of records of knowledge in the immortal cultivation world, and does not involve some cultivation exercises and spells, but it is also collected and sorted out by our Mu family after hundreds of years, this time I was called by my grandfather now, I'm afraid I can't take you into the library pavilion" Li Daoyuan took the jade pendant and said thank you,

"Senior brother, you are too polite, it should be the little sister who thanked the senior brother for saving her life twice" Mu Ying'er said with a reluctant smile, it seemed that she was still very worried about suddenly facing the patriarch next. Pen, fun, and www.biquge.info

Li Daoyuan nodded to Mu Ying'er with a smile, and then said to Mu Qing on the side, "Senior Brother Mu, I don't think there is any need to trouble the two senior brothers Wuren and Ma Liang, I also know the way to the Welcome Building, so I'll take Lu Qi over by myself."

Lu Qi also echoed on the side, "Don't bother the two senior brothers so much"

Seeing this, Mu Qing had no choice but to nod and agree, and immediately gave Mu Ying'er and Jia Yuan a look, and took the lead to leave the garden.

At the entrance of the seventh floor of the Welcome Building, Li Daoyuan was standing behind Lu Qi, who was watching Lu Qi for the fifth time and was mercilessly bounced back by the thirteen layers of paper-thin blue light in the staircase.

For the first time, Lu Qi's five fingers became claws, and one claw was wrapped in white true qi and penetrated the blue light formed by the ban, Li Daoyuan thought that he had passed the ban on the welcome building, who knew that the blue light was not as broken as Li Daoyuan imagined, but in a breath, Lu Qi's five fingers through the blue light were wrapped in the blue light and rebounded back, which made Lu Qi take a few steps back unnoticed, and when he looked at the blue light in front of him, it was intact again. Next, Lu Qi changed several methods that made Li Daoyuan feel dangerous, but they were all easily blocked by the few thin pieces of blue light in front of him.

"This welcome building should have thirteen nodes, when you attack any place, you will be rebounded by thirteen layers of blue light, even if I attack with all my strength, I can only penetrate the twelve layers of blue light, if I want to fight again, it will definitely attract the inspection of the Mu family" Lu Qi looked at the prohibition in front of him and said helplessly

"Why, Senior Brother Lu still has research on the way of formation" Li Daoyuan couldn't help but ask curiously, Li Daoyuan himself didn't know anything about the way of formation,

"Little brother, I also learned a rough idea from the books, the power of each formation is measured by the number of nodes in the formation diagram, but the formation is also divided into various categories, there are attack, auxiliary and defensive these most common categories, this should be the second-level formation in front of us that is known for its defensive power, mille-feuille" Lu Qi then set his eyes on the thick solid mahogany pillar in the middle of the welcome building.

Li Daoyuan also looked at Lu Qi's eyes, but the dense notches on the mahogany pillar, Li Daoyuan had no clue in his eyes, and he didn't know which line was the starting point and which line was the end, just like the feeling when he first looked at the meridian route map, the meridian route map!

Simply give it a try, Li Daoyuan walked to the mahogany pillar, raised his right hand, and pressed his palm on the red pillar, the spiritual power of the Huangshan Jue in his body was slowly injected into it, and after a few breaths, the lines carved on the red pillar were emerald green blue light and disappeared quickly.

This method is useful, although the blue light is as fast as lightning, it was still captured by Li Daoyuan and Jia Yuan,

"The node of the sixth layer is here?" The two of them walked over to the gathering place of the blue light that flashed just now, and a formation line pointed by Lu Qi asked Li Daoyuan curiously.

"I just happened to have some similarities between the path map of the sensory formation formation and the operation diagram of the meridians, so I tried it randomly, whether this is the node of the sixth layer, I am not sure, by the way, Brother Lu, I have heard the master talk about the white flame volcano-level large array in Xilan City before, this mountain-level large array is considered to be a few levels of large array" Li Daoyuan also looked at the node on the sixth floor of the suspected welcome building, but Li Daoyuan still couldn't see a reason at this time.

"Brother Li made a joke," Lu Qi no longer paid attention to the formation map line on the mahogany pillar, and continued,

"Formations below ten nodes are referred to as first-level formations, and so on, to ninety-nine nodes of ten-level formations, there are one hundred nodes of formations can be called mountain-level arrays, and the position of the center of each formation is the spiritual power center of this formation, also known as the eye of the formation."

"Oh, I see, how do you have to do the way of the formation to crack it?" Li Daoyuan is now more and more interested in the way of the formation

"Let's take this thousand-layer emerald second-level formation with thirteen nodes as an example, there are two ways to crack it, the first method is like what I just did, use brute force to crack this array, and one force to reduce ten thousand methods is the truth of the past, the second one is easier, but it is also more troublesome, to find out all the nodes of this array, and then attack these thirteen nodes at the same time, when the time comes, you only need to easily break through the first layer of cyan light prohibition, and this thousand-layer emerald formation will be completely invalid." Lu Qi snapped his fingers and told Li Daoyuan everything he knew.

Next, Lu Qi honestly found a guest room on the sixth floor, Li Daoyuan chatted with him in his room for a while, and after a quarter of an hour, the time was not early, and he immediately said goodbye and left.

Li Daoyuan did not stop when he reached the ninth floor, but walked towards the entrance to the tenth-floor building, Li Daoyuan had seen Lu Qi attack the Thousand Layer Emerald Formation, and now he also wanted to try the power and effect of the formation.

I saw Li Daoyuan open his five fingers with one hand, and his slender five fingers slowly pushed towards the ten-story staircase, but the expected cyan forbidden light curtain did not appear.

Li Daoyuan's first reaction at this time was to unknowingly enter the tenth layer of qi refining, Li Daoyuan hurriedly looked inside the spiritual power in the dantian with his divine thoughts.

"It's weird, it's clearly the total amount of aura at the ninth layer of qi refining" Li Daoyuan muttered in a low voice at the moment,

Ignoring it, Li Daoyuan raised his head and strode towards the entrance of the tenth floor, when Li Daoyuan calmly stepped over the stairs without encountering any obstacles, and came to the tenth floor of the welcome building.

That's when he remembered why.

Li Daoyuan shook his head and smiled, he wanted to test the power of the formation twice, but he was interrupted by accident both times, Li Daoyuan retreated to the guest room he had chosen on the ninth floor, and took out the identity token given to him by Mu Ying'er from the clothes belt.

It is this thing that makes Li Daoyuan unimpeded in the welcome building.
