There is another mystery on the top floor of the Yaoshan Technique Building, and Lu Yi only learned about it after he came back as a spiritual cultivator this time. According to the instructions, Lu Yi found a middle-aged monk in an inconspicuous small room on the top floor of the Shuji Building, Lu Yi respectfully explained his intention to this monk who was already a complete spiritual building, and the other party smiled and stared at Lu Yi for a long time before breaking open a space and letting Lu Yi walk in.

Inside is a space fragment that has been captured and fixed here, the area is not large, only about a thousand zhang, but five small buildings have been established, each small building has a separate prohibition, corresponding to the early stage of spirit building to the consummation of spirit building and the heavenly level monks, only when you reach the corresponding level can you enter the corresponding small building and a small building one level higher than yourself. Because Lu Yi was highly valued by the high-level, he was allowed to enter the small building at the level of a late-stage monk to read the information inside, but he only had one chance to enter the late-stage building of the spirit-building stage. Lu Yi chose to directly enter the small building in the late stage of spirit building, he held a jade plate in his hand, and when he arrived at the door of the small building, Lu Yi poured some spiritual power into it, and the jade card suddenly shattered, forming a spiritual aura that completely enveloped Lu Yi, under the protection of the aura, Lu Yi raised his feet and stepped into the small building, he could clearly feel that when he passed through the prohibition at the door, the aura was attacked, and after Lu Yi entered the door, the aura disappeared. Lu Yi looked at another jade plate in his hand that was exactly the same as the jade plate just now, this is what he needs when he goes out, otherwise without its protection, Lu Yi will also be attacked and trigger the alarm when he goes out, and at that time, someone will come to see what is going on here, and impose sanctions on the trespassers.

This is one of the most important places in Yaoshan, otherwise the spiritual consummation monk will not be used to personally control the door, the contents are not allowed to be taken away, not allowed to be copied, can only be watched in it, and each entry shall not exceed three days, and each person can only enter once within ten years, and the strict control is the only thing Lu Yi has seen since he entered Yaoshan. Lu Yi's purpose in coming here was to find information about the half-demon, so after he entered the building, he quickly took out jade slips from the rows of shelves, and probed his spiritual power into it. I have to say that the collection of Yaoshan is still very rich, and there are thousands of jade slips in this small building, including all the materials such as exercises, spells, pills, formations, etc., which are equivalent to the cultivation of monks in the late stage of soul building, as well as some cultivation experiences and even doubts left by the ancestors, etc., and there are also some rumors and conjectures related to the late stage of spirit building.

Lu Yi looked through every jade slip in the building, and sighed in disappointment, there was nothing he was looking for here. Calculating the time, he has been in this building for almost twelve hours, Lu Yi quickly took a few jade slips that he had noticed before in his hand, and looked through them carefully, these jade slips recorded a tenth-order magic array, although Lu Yi can't comprehend it now, but he can say it to Venerable Li Tian, let him help him forcibly memorize it, and then slowly study it in the formation of the extension after he goes out. Because there were two other small buildings to check, Lu Yi didn't waste too much time, after all, the tenth-order magic array was not enough for Lu Yi's current strength to set foot in, so he asked Venerable Li Tian to memorize it and left in a hurry.

Crushed the jade plate again, and left the small building under the protection of the jade plate, Lu Yi turned his head and entered the small building of the monk in the middle stage of spiritual building, and there was no need for protection when he entered here, and there was no change after the prohibition at the door swept Lu Yi. Lu Yi raised his eyes and scanned the items stored in this small building, and found that there were as many as two or three thousand pieces, Lu Yi was afraid that there would be not enough time, so he was busy devoting himself to the work of finding half-demon information. This time the workload was much larger, so Lu Yi looked at it more roughly, almost took the jade slip and scanned it briefly, and found that it had nothing to do with the information of the half-demon, so he put it down and looked at the other one. Rao is like this, when Lu Yi went through the inventory in the small building, it was already twelve hours. Lu Yi, who had found nothing, had to quickly withdraw from the small building that came to the early stage of spirit building, and he felt that there might be more things here. Sure enough, when Lu Yi saw a room full of jade slips, his head was a little big, there were nearly 10,000 jade slips! Not to mention one day, even if you spend three days here, you can't finish it!

Lu Yi didn't have time to sigh, he could only look at it at a faster speed, in order to save time, Lu Yi didn't even have time to put the jade slip back in place, and after reading one with one hand, he put it down casually, and immediately put his energy into the jade slip in the other hand.

Lu Yi had forgotten the concept of time and space, and everywhere he walked, Yu Jian was thrown everywhere in a mess, until a sudden voice sounded and startled Lu Yi, which pulled him back to reality.
