Searching for the so-called "base" in the Infinite Sea was fruitless, it took so long to waste, Xu Dong's cultivation had been abolished for a long time, which made him feel upset, just like he had said to Xu Li before, no matter what the result of the reconnaissance in the Infinite Sea was, he had to go back to the Pure Yang Palace to resume his cultivation.

Continuing to leave Xing Yu to escort Xiao Sanqi, Xu Dong gave Xiao Sanqi the only remaining piece of "Bilongju", took the others back to Wuliang Island by Qiankun Yin, and made a short stay on Wuliang Island, and after making a little arrangement for the "Immigration Army" and Wuliang Sect, he went to Chunyang Palace through the teleportation array.

Temporarily give up the ambush of the Infinite Sea Islands, go back to the Pure Yang Palace to calm down and cultivate, this is what the Holy Infant once proposed, Xu Li also had such a suggestion, Xu Dong now adopts this opinion, thinking that it will be more powerful to take back the fist and practice it hard before hitting it.

He could have had four choices, cultivating in Wuliang Island, Pure Yang Palace, Lotus 'Flower' and 'Cave' and Liuli 'Cave', but he chose to cultivate in Pure Yang Palace because he wanted to cultivate the Great Yan Gong this time, he might have to be guided by Xu Li.

After returning to the Pure Yang Palace, he originally planned to retreat in the underground dark room as before, but after thinking about it, he decided to change places this time, he felt that it was more appropriate to cultivate in the underground treasure house, first, for safety reasons, and secondly, there was an important thing in the treasure house, the planetarium, and he could monitor the changes in the national fortune through the planetarium at any time.

When he informed Xu Li of this idea, Xu Li seemed a little surprised, but since the emperor had decided, he was only a courtier and had the role of execution, so he accompanied Xu Dong to the "Essence" Hall located at the southern end of the Chunyang Palace.

The two walked into the "Essence" Palace, and found the entrance of the underground treasure house through a secret passage, and saw that there were two heavy stone vaults at the entrance, and a heavy gold lock was hung on the stone vault 'door'.

"Your Majesty, the minister has to stop here, and he can't accompany the emperor into the underground treasure house, so the emperor will go in alone. ”

Xu Dong understood Xu Li's intentions, because the founding monarch had special regulations on this underground treasure house, and non-successor monarchs themselves were not allowed to enter the underground treasure house, he instructed, "Xu Aiqing, you have to find some masters to guard outside the 'Jing' Palace, and also, during my retreat, you let the two fathers-in-law of the pot and shovel take turns to be on duty here, and I can summon them at any time if I have anything." ”

Xu Li nodded, "Your Majesty, the ministers must do as the emperor instructs, so you can go in with confidence." ”

Xu Dong took out the golden key from the treasure bag, and Zhao Lun's voice suddenly sounded in his ears, "This is the key to the underground treasure house of the Luotuo Kingdom, and now I will 'hand' it over to you, which means that I have completely abandoned the Luotuo Kingdom......

Did Zhao Lun really give up on Luo Tuoguo, Xu Dong thought of it with a strong sense of ridicule.

He opened the golden lock on the 'door' of the stone vault, pushed open the two heavy stone 'doors' and walked into the underground treasure house alone, although this was not the first time he had entered the underground treasure house, but he was still stunned by the dazzling scenes inside.

The space of the entire underground treasure house is not large, the length and width are no more than ten zhang, it is an irregular rectangle, and there are several cabinets made of pure gold against the wall on all sides, these cabinets emit a dull golden light, each cabinet is stuffed with items for cultivation, one cabinet is stacked with exercise cheats, one cabinet is filled with various spiritual weapons, and the other cabinet is filled with many superb pills.

He had opened these exercises casually before, including the magic 'gate' thaumaturgy, the inner pill exercises, and even the Shura martial arts scriptures and some evil 'door' different skills, and then looked at the magic weapons placed in the cabinet next to him, he didn't know most of these magic weapons, let alone the mana and use of these things, including a few magic swords, two copper compasses, and a few magic tools such as banners......

"I have to 'hand' over a few words to you, you can choose a few exercises and cheats in the underground treasure house to cultivate, but before you cultivate to the distraction realm, you'd better not move those few spiritual weapons, because the anti-devouring power of these spiritual weapons is very strong. ”

Xu Dong remembered what Zhao Lun had said emphatically, but this sentence didn't seem to work, because he had already practiced to the distraction realm now, and he was just about to break through the last bottleneck and step into the out-of-body realm in one step, but he had no intention of taking anything in the cabinet.

However, his eyes involuntarily searched for one thing, that is, the planetarium placed on the top of the cabinet, he remembered that there was a button at the bottom of the planetarium, and when he flicked that button, the planetarium could project cloud images on the sky 'flower' board, from which he could see the rise and fall of the country's fortunes.

Xu Dong flicked the button above, the planetarium slowly rotated, and a beam of blue 'color' light flame was projected on the sky 'flower' board of the underground treasure house, forming a starry sky on the top of the dome of the sky 'flower' board, and countless stars shone on it, covering the entire underground treasure house with a pale blue 'color' of starlight.

His eyes were immediately attracted by the starry sky, which was so pure that there was no impurity, countless stars shining in it, a river Han lay across the blue canopy, there were stars as dense as the sand of the Ganges River, and there were a few shining giant stars on each side of the Milky Way, and there was no need to guess that it was the legendary Cowherd and Weaver 'Girl'.

Xu Dong found the constellations he knew in this vault, of course, the first thing he found was the Big Dipper, the seven giant stars were distributed in the shape of a spoon, slowly rotating around the golden nail-like North Star, with the positioning of the Seven Stars Beidou, he was easy to find the constellations he was familiar with, and effortlessly found twenty-eight constellations, all the constellations whose names he knew and those whose names he didn't know were found by him one by one.

Suddenly, there was a strange sound in the underground treasure house, Xu Dong looked back, these strange sounds came from those spiritual weapons, almost every spiritual weapon was roaring, and this sound was like a muffled thunder rolling in the sky.

The planetarium drove the spirit weapon to roar, Xu Dong had seen it before, so it was not as flustered as when he first encountered it, and after a while, the underground treasure house suddenly returned to peace, which spirit weapon no longer made a sound, raised his head to look at the vault above, and reproduced a quiet blue 'color' starry sky.

Xu Dong took out the book of Dayan Gong from the treasure bag, and began to comprehend it from the first page, and he didn't understand it for two days in a row but didn't know the essentials, not that the text on it was obscure, compared to other exercises, it was very simple, but the artistic conception inside was circuitous, making him feel like walking into a 'labyrinth' palace, even if you tried your best, you couldn't get out for a while.

He closed this book of Dayan gourd Gong, opened the 'door' of the underground treasure house, and sure enough, he saw the shovel shovel on duty at the entrance of this passage of the "Hua'jing' Palace", he ordered the shovel, "Quickly call Prime Minister Xu over, I have something urgent to find him." ”

"Yes, Your Majesty. Shovel Shovel hurriedly led the order out of the "Essence" Palace.

Xu Li soon followed his father-in-law to the "Turning 'Essence' Palace", and as soon as Xu Li saw Xu Dong, he guessed why he was looking for him, "Your Majesty, did you have a problem when you participated in the Great Yan Gong." ”

Xu Dong nodded and said, "Exactly, Xu Aiqing, have you ever participated in this exercise, how can I be surrounded by it, 'getting' to be dizzy." ”

"Back to the emperor, the minister began to comprehend this exercise half a year ago, and at the beginning there was also the situation that the emperor said, but now I have a preliminary understanding, this exercise is different from other exercises after all, because it is the culmination of the dual cultivation of the demon and the Tao, and the demon and the Tao are inherently mutually exclusive, but in the end, they can go to the same end and reach the realm of the unity of heaven and man......"

Xu Dong felt that Xu Li's explanation was redundant, so he interrupted him, "Xu Aiqing, you just say straightforwardly, how long will it take for me to understand the realm of this exercise." ”

Xu Li seemed to guess that Xu Dong had such a question, and he didn't think about it, so he said, "Ordinary people can't understand the realm of this exercise for two thousand years, it takes about four or five hundred years for a dragon spirit root practitioner, and it takes two hundred years for a practitioner like Ruchen who has a certain foundation for the dual cultivation of the Demon Dao, and a cultivation genius like the emperor can comprehend it in less than a year." ”

Xu Dong almost shouted, "What kind of bullshit exercises, it will take me a year just to comprehend, if you practice it, it won't take longer, I don't want to practice this bullshit exercises, go to his demonic path double cultivation." ”

In fact, Xu Dong just said the above words in his heart, but Xu Li read it from his expression, "Don't worry, the emperor, now that the emperor's reunification has been completed, the country's fortunes are prosperous, and the world is peaceful, the emperor will be at ease with his own cultivation, and those complicated state affairs will be 'handed over' to the ministers and a group of civil and military ministers." ”

Xu Dong hurriedly said, "Let's go, because the power of the demon, Dao, and demon factions is concentrated in the Infinite Sea, it seems that if I don't practice the Great Yan Gongzigong, it will be difficult to complete the cause of conquering the islands of the Infinite Sea, so I will cultivate according to Xu Aiqing's peace of mind." ”

After Xu Li left, Xu Dong returned to the underground treasure house, he decided to speed up the comprehension of the Great Yan Gong, if it was not possible in the past, but now that he has this condition, he took out the three-in-one accelerator from the treasure bag, and prepared to enter the accelerator to participate in the Great Yan Gong.

But just as he was about to enter the accelerator, the entire underground treasure house suddenly darkened, and everything in the treasure house was hidden in the darkness, and only the spirit weapons began to roar again.

He looked up at the dome-shaped canopy, and in an instant the sky changed, and the original pure blue starry sky was gone, replaced by a dull and chaotic space, as if entering a long dark night.

Lightning flashes appeared in the dark sky, as if the entire vault had suddenly exploded, followed by even more terrifying celestial phenomena, solar and lunar eclipses appeared alternately, tsunamis and hurricanes swept the ground one after another, and even celestial bodies capsized, and many stars exploded to form meteorite rain one after another......

Xu Dong felt that the entire underground treasure house was trembling, and the spiritual weapons continued to roar, and he himself felt as if he was in the midst of one disaster after another, his body rising and falling with the violent celestial phenomena.

Zhao Lun's face suddenly flashed in front of his eyes, that face was like a mask that had been forcefully squeezed and twisted, and the long beard of a ruler was gray and messy, but his mouth could still speak, "There is a planetarium in the underground treasure house, and from the cloud map above you can see the rise and fall of the national fortunes, as far as I can see, five to six years later, there will be a catastrophe in the Ratuo Congress. ”

Xu Dong was taken aback, and he had a comprehension of the projection of this planetarium, it must have been something changed outside, Luo Tuoguo and himself were about to face an extremely severe test, which caused the planetarium to have a vision, he hurriedly took the accelerator back to the treasure bag, opened the 'door' of the underground treasure house and walked out.
