At this moment, Xu Changqing could hear that Du Qitian was indeed sincere in cooperating with the invitees who went to the treasure house of the Taishang Qingjing Heaven Dynasty this time, and there was no atmosphere of crossing the river and demolishing the bridge, but he could still feel that what Du Qitian wanted to get when he entered the treasure house was not as simple as the so-called complete Jiuding Zhenyue Qitian**. So he carefully recalled the conversation between Du Qitian and the rest of the Du family just now, and quickly found the key, and was vaguely able to guess what Du Qitian wanted to find in the treasure house of the Taishang Qingjing Heavenly Dynasty.

In the Kunlun Immortal Realm, when it comes to the Taishang Qingjingtian Dynasty, all that comes to everyone's mind is the honorific title of the Taishang Chengtian Houde Dao Saint Monarch Haotian, as for the immortals who built the entire Taishang Qingjingtian Dynasty, few people remember, and only a few ancient books will slightly record the deeds of some other immortals, such as Shao Xun and the ancestor of the Du family, King Xizhen. In the short-lived Taishang Qingjing Heavenly Dynasty. The light of the Haotian Emperor was so dazzling that it covered up all the qiē around him, and all that could be seen by everyone's eyes was his light. However, Haotian's personal strength was only a part of the Taishang Qingjing Heavenly Dynasty. There are still some people around Haotian who will never be much worse than Haotian, and the Quartet Niangniang, who is the emperor, is one of them.

Xu Changqing has read the ancient books that mention Taishang Qingjing Tian Sifang Niangniang, in which some things about Mingxia Niangniang in the West have been recorded, and the focus is also on Mingxia Niangniang's natal spiritual treasure. The most famous spiritual treasure of Mingxia Niangniang in the West is none other than Yunyan Xianxiapa. This spiritual treasure was placed in the inner treasury of the Taishang Qingjingtian Treasure House along with Mingxia Niangniang, but now it has been found out of the treasure house and has become the natal spiritual treasure of Yuxuan Zhenren Yunsheng, the sect leader of the outer gate of Louguan Dao.

In addition to Yunyan Xianxiapa, Mingxia Niangniang also has a set of unknown spiritual treasures, this set of spiritual treasures is composed of three innate spiritual lamps, one of which is the immortal lamp of all things mentioned by Du Junwu just now, as for the names and shapes of the other two spiritual lamps are not found in words and legends. It's just that now it seems that Xu Changqing can guess the location of the other two innate spirit lamps that must have the location of the Pure World Lamp.

Xu Changqing also knew a lot about the innate spirit lamps that appeared in ancient times, but he couldn't know these innate spirit lamps and those that existed from Zhen Yuanzi's memory. In his memory, the Pure World Lamp is one of them, and according to legend, the Tongtian Divine Lamp in the Shangqing Sect's Mountain Gate Hall should also be an ancient spiritual treasure, and the aforementioned Immortal Lantern of All Things is not handed down from ancient times, and is likely to come from Kunlun Immortals. Therefore, Xu Changqing couldn't guess the origin and utility of the last spiritual lamp, and he couldn't guess what the magic of this set of three innate spiritual lamps combined was from the strength of the spiritual lanterns. The only thing he knew was that Du Qitian and his son must have known what the use of these three spiritual lanterns would be when they were gathered together. Because if the ancient books are not mistaken, then the Western Mingxia Niangniang is also surnamed Du. and the ancestor of the Du family, the king of Western Town, are sisters and brothers.

Du Qitian and his son still don't know that their every move is being seen, although Du Qitian is already a supreme immortal, but the time he has been a supreme immortal is too short, and he is not familiar with the power he now obtains from the Great Dao of Heaven and Earth, plus the confidence of their father and son in the surrounding formations. This makes their vigilance drop to the extreme. If it was a demon suppression Tianzun who had become a supreme immortal for thousands of years, even if Xu Changqing had the Great Luo Golden Immortal Divine Thought, he would not dare to snoop so blatantly.

After that, Du Qitian's father and son discussed the plan that should be carried out after Du Qitian left, if Xu Changqing was a person who was hostile to the Du family, the content of these plans he heard was enough for him to completely disappear the Du family in a short period of time. Fortunately, Xu Changqing thought that the Du family's survival was beneficial to his plan, and Du Qitian was this. People are also worth befriending, so when he talked about the details of Ji Zai in the Du family's father and son, he quietly withdrew his divine thoughts, and instead absorbed the surrounding spiritual energy to restore his mana and cultivate.

Wufu Mountain itself is the place where the spiritual veins of the Outer Gate Spirit Mountain gather, and all the spiritual veins of the three elixir mountains together are only one-third of all the spiritual veins of Wufu Mountain. Although there are many spiritual veins in Wufu Mountain, it is also chaotic because of the large number of spiritual veins. The aura is impure and conflicting with each other, and the pulsations that will arise every month will cause the turbulence of the aura, which is no less than a disaster for the vast majority of low-grade immortals. Like the three elixir mountains, the spiritual qi is peaceful and the spiritual veins with weak pulsations, and the other five spiritual mountains are very few, and there are even fewer places suitable for cultivating elixirs.

The spiritual vein where Cloud City is located should be a main vein, and its branches should be the spiritual vein that extends to the Thousand Miasma Forest Sea. The aura in this spiritual vein is also quite peaceful because of the Zhenyun Rending formed by the heads of the families in the ancestral temple of the Du family, so the aura is also a lot calmer, which is very suitable for the cultivation of immortals. Although Xu Changqing's position was not the center of the entire spiritual vein. But it is also around the gathering point of the spiritual veins, where you can absorb the immortal qi for a night. It is enough to restore its cultivation a lot, although it is not as effective as that cup of immortal drunkenness.

In the early morning of the next day, Du Qitian came to the small courtyard where Xu Changqing was staying, and led Xu Changqing to the Du family's collection and took it to Ying Chuan'er's order. Judging from his relaxed expression, he couldn't tell that he had quarreled with his family yesterday.

The Du family collection is located on a small hill on the southwest side of the main house, where nearly a hundred dead soldiers who are only loyal to the Du family are stationed, and the cultivation of each dead soldier has the realm of Jindan Hengfeng, and ten of the immortals of the main array are even more in the realm of returning to the void. Judging from its mana aura, the Dao method cultivated by every dead soldier is the same. And they all use a formation flag as their natal magic weapon, whether it is mana or magic weapon. They are all closely connected to the formation under the hill, regardless of each other. If someone dares to break in, they will not hesitate to kill them, although a single cultivation is not very good, but when they are connected by the formation, and there is a whole spiritual vein as a backing, even if the strongest immortal is here, I am afraid that they will be trapped for a while.

These dead men are also extremely rigorous in their work. Although Du Qitian was the previous head of the Du family, he still needed to show the seal signed by the current head of the family and the elders of the clan before he and Xu Changqing could be allowed to enter, and he also sent ten people to accompany him to enter, and his behavior looked extremely distrustful of Du Qitian.

Seeing this, Xu Changqing suddenly said: "According to legend, the ancestor of the Du family is the famous god general of the Taishang Qingjing Heavenly Dynasty, the king of the western town, and today, when I see it, these children of the Du family are doing things to the point that some soldiers have banned them, and it seems that the rumors have a root!"

Du Qitian was slightly stunned, looked at Xu Changqing with surprise, and said with a straight smile: "I didn't expect that there are still people in the outside world who remember the matter of my Du family's ancestors, which is really a bit surprising to the old man." It's a pity that the children of my Du family are not filial, and the Taoism in the family has been lost a lot. In the end, I just learned a little bit of skin!" he said, sighed, and then looked at the dead man who was opening the forbidden door of the vault and said: "These keepers are the same as my Du family's family, they are all in the same lineage, all the keepers of the library are already destined to be born with an identity, and they will not be loyal to anyone, only to the Du family." Even if it's an old man. If you want to enter the vault, you also need to follow the rules. Otherwise, they won't ask for any reason. will directly kill the old man. ”

Referring to these library keepers, Du Qitian looked with a trace of dissatisfaction and pity, but he didn't talk about it deeply. After the library keeper opened the door, he led Xu Changqing into the treasury with him.

The Du family's treasury was not as messy as Xu Changqing imagined, all the magic weapons were sealed in a box, neatly placed in a specially made zuò spirit wood lattice cabinet, and the name and location number of this treasure were engraved with jade on the outside. All the cabinets are arranged in four rows, each row is in the vertical and horizontal twelve positions of the heavenly and terrestrial branches, a total of 120 cabinets are placed, and the number of wooden boxes stored in each cabinet is different, and the total number of wooden boxes in the warehouse is roughly estimated to be about 10,000.

After Du Qitian walked in, he introduced to Xu Changqing: "Most of the treasures collected by my Du family here are the magic weapons left by the sages of the Du family in the past dynasties, in addition to some high-grade elixirs, ancient relics and Taoist fragments found, although they are much inferior to the treasures of the great sects and the treasures of the Dragon Palace. But it also has its own peculiarities. ”

Hearing Du Qitian's words, Xu Changqing nodded slightly in agreement. In his eyes, the Du family's treasures are indeed very unique, and most of the treasures here are just magic weapons, and there are no spiritual treasures. It's just that because these magic weapons are the natal magic weapons of the ancestors of the Du family, they are integrated into the essence of the original holder's life, so that these magic weapons are no less than ordinary low-grade spiritual treasures in terms of spiritual light and mana alone. A single such magic weapon was nothing, but nearly eight thousand magic weapons of the same origin of mana were placed together at the same time. Even if there is a formation ban, the invisible coercion it exudes is incomparably huge. Even Xu Changqing felt the same sense of restraint the moment he just came in

Xu Changqing's divine thoughts spread out in the vault, and silently penetrated into the boxes. Look for something that works for you. At the same time, he asked: "Elder Du, yesterday I didn't seem to have such a high-grade magic weapon on the children of the Du family, there are so many magic weapons here, why don't you give them to the children of the Du family to use?"

"Brother doesn't know, because these magic weapons are the natal magic weapons of the ancestors, the magic weapons contain some of the habits of the ancestors, and not every child of the Du family can use these magic weapons. Du Qitian smiled and explained: "Actually, my Du family's family, the East and West Mansions, every year, will gather the children who have entered the Jindan realm to look for a suitable magic weapon that can be used. It's just that there are less than ten children who can find a suitable magic weapon in a year. In this way, there are more and more treasures in this vault, and in a few years. Maybe another repository will have to be built. Dedicated to the collection of these natal magic weapons. As he spoke, he quickly looked through the library book in his hand, found the location of the fairy stone from the booklet, and then asked the library keeper to take it out and put it in front of Xu Changqing. Ordered someone to open the seal on the box, and then said: "This is the fragment of the leading immortal stone, I don't know if it is what my brother wants."
