Chapter 819 Stone House and Flint

This successfully refined seventh-level Nine Palaces and Eight Diagrams formation occupies an area of ​​nearly forty miles.

After the formation was completely arranged in the cave heaven spirit domain, Wu Yan sensed it with his spiritual sense, and then opened his vertical eyes to check for a moment, and finally confirmed that although this space formation was arranged in the cave heaven spirit domain with incomplete laws, the opened formation seemed to be an isolated independent world, which was obviously different from the outside cave heaven spirit domain.

However, the number of spirit stones required to maintain this space formation is still relatively large. In almost a year, hundreds of top-grade spirit stones are needed.

Think about the Wuji Suoyuan formation that protected Xuanyuan Island in the Wuliang Xumi Cave Heaven. Although the area was as large as thousands of miles, it only needed ninety top-grade spirit stones every year. Of course, the Wuji Suoyuan Formation was only a fifth-level formation after all, and the Nine Palaces and Eight Diagrams Formation in front of him, although the area protected was far from being comparable to the Wuji Suoyuan Formation, was two levels higher than the Wuji Suoyuan Formation in terms of level. It was reasonable to have such a large consumption.

After arranging this formation, Wu Yan summoned Zhuang Shangui again and arranged for him to carry out the plan to move the medicine garden.

This was the first time that Wu Yan was preparing to move the outside world into the Dongtian Spiritual Realm, so he was very cautious. This was very different from the previous practice of driving the spirit veins into the Dongtian Spiritual Realm. The spirit veins can be collected with special techniques and then driven into the earth veins in the Dongtian Spiritual Realm. However, to move the external mountains, rivers, and earth into the Dongtian, the mountain gods, land, and mountain movers in the Dongtian needed to take action.

Wu Yan's virtual god domain has not yet been completely integrated with the entire Dongtian Spiritual Realm, so naturally he cannot personally move the mountains, rivers, and earth directly into the Dongtian Spiritual Realm. Of course, for such heavy work, most powerful cultivators would also order the spirit gods or guardian beasts in the cave to take action. This is why every powerful cultivator who owns a cave will recruit some spirit gods.

After seeing the Nine Palaces and Eight Diagrams Formation was set up, Zhuang Shan Gui was full of praise. When he heard Wu Yan's order to move the mountain, he immediately patted his chest and guaranteed: "Don't worry, my lord, I know what to do. Since I joined the lord, I and other lands have never had the opportunity to perform in front of you, my lord. This time I will never let you down. You see, our mountain movers are not trained in vain."

Wu Yan nodded, without saying anything more, but released part of the cave spirit domain and covered the entire medicine valley medicine garden.

As the cave spirit domain bordered the entire medicine valley medicine garden, more than a dozen mountain gods and lands and mountain movers, under the command of Zhuang Shan Gui, suddenly appeared around the medicine valley medicine garden.

Zhuang Shan Gui first measured the entire Medicine Valley and Medicine Garden, and then sent several land gods to sneak underground, check it out, and formulate a complete plan for moving mountains.

A few moments later, Zhuang Shan Gui showed a confident expression on his face. He commanded eight land gods to escape underground, and arranged six mountain movers to be stationed in six directions of the entire medicine garden, and began to move the entire Medicine Valley and Medicine Garden into the Cave Heaven Spirit Realm.

With the continuous flashing of spiritual light, the entire Medicine Valley and Medicine Garden was slowly pushed up from below. At this moment, the six mountain movers, all of them flushed red, and their hands grabbed the rising Medicine Valley and Medicine Garden very rhythmically and pushed it up.

A few more moments passed, and a huge circular mound of earth with a radius of several miles and a depth of several miles was wrapped in spiritual light. Under the joint efforts of more than a dozen mountain gods, land gods and mountain movers, it was moved into the Cave Heaven Spirit Realm little by little.

The original medicine garden was left with only a huge pit. At the bottom center of the pit, there is a very strange stone house. It can be seen that if the medicine valley and medicine garden have not been moved away, this stone house should be a hidden secret room several miles underground. There are five fire spirit vein exits around the stone house, each of which emits extremely strong and terrifying high temperatures.

However, because it is blocked by an invisible formation, the five fire vein exits, although there is extremely strong fire power, cannot really spray out fire vein magma.

After watching for a while, Wu Yan nodded secretly. This place is exactly the same as what he saw with his eyes. This stone house is the only teleportation array gate outside the entire volcanic pit valley that can enter the first level of the fairy array below. There is no such teleportation array under the medicine gardens in the other three directions. Otherwise, Wu Yan would not have chosen to seize this medicine garden.

After the Medicine Valley and Medicine Garden were moved into the Cave Heaven Spirit Realm, Zhuang Shan Gui became more and more adept at controlling the Medicine Valley and Medicine Garden, and soon placed the Medicine Valley and Medicine Garden in the Wu Earth Palace in the center of the Nine Palaces and Eight Diagrams Formation.

Although the miniature immortal medicine vein below is small, its role in the medicine garden is immeasurable. Almost as soon as the Medicine Valley and Medicine Garden were placed in the Wu Earth Palace, the spiritual energy in the veins from all directions almost all converged in the direction of the immortal medicine vein.

Even without Zhuang Shan Gui and other mountain gods and land gods taking action, the immortal medicine vein began to slowly merge with the spiritual veins in the Cave Heaven Spirit Realm.

Wu Yan's spiritual sense swept across the entire Medicine Valley and Medicine Garden, and he realized that there was nothing wrong with the immortal grass, immortal fruit and spiritual roots in the entire medicine garden after being placed here, so he breathed a sigh of relief.

Finally, the medicine garden was successfully moved into the Cave Heaven Spirit Realm, making an independent and usable medicine garden in the Spirit Realm.

"My Lord, these are some strange crystals I found when I was moving the mountain. I found them at the junction of the immortal medicine vein and the fire spirit vein below the medicine valley. I can't identify what kind of crystals they are, but I realize that the immortal medicine vein can use these crystals to harmonize the fire attribute spiritual power of the fire spirit vein and nourish the immortal medicine vein, so I dare to take these crystals. Please make your decision." Zhuang Shangui held five fist-sized pale yellow crystals in his hands and reported to Wu Yan.

Wu Yan's eyes fell on the five crystals, and he was slightly startled. Then he raised his hand and collected all the five crystals as if nothing had happened, and smiled: "Very good, you did a good job. Keep this formation flag. I will let you guard this medicine garden in the future."

As he said, Wu Yan handed a formation flag that opened the Wu Earth Palace to Zhuang Shan Gui. Zhuang Shan Gui showed great joy on his face and said respectfully: "Thank you for your trust, my lord. I will take good care of the immortal medicines in the medicine garden!"

"Go!" Wu Yan waved his hand, and Zhuang Shan Gui happily hugged the formation flag and fled to the Wu Earth Palace of the Nine Palaces and Eight Diagrams Formation.

Wu Yan escaped directly from the Dongtian Spiritual Realm, put away the Great Wilderness Yuan Ding, and then took out the five fist-sized crystals he had just taken from Zhuang Shan Gui.

"No wonder, although this place is at the crater of the volcano, the immortal medicine veins under the medicine garden are not affected by the fire of the volcano at all, and the spiritual energy in them is even richer than other places! It seems that the five fire spirit veins below are able to continuously provide spiritual power to the immortal medicine veins without being affected by the high temperature fire veins because of the blending of these five ordinary fire flints."

These five fist-sized crystal stones are the ordinary fire flints that Wu Yan has been looking for. Although he had obtained two ordinary fire flints before, their sizes were not comparable to the five ordinary fire flints in his hand.

Wu Yan did not hesitate at all, and directly took out the flame essence flint from the green clam shell and began to absorb the ordinary fire source in these five ordinary fire flints.

After a while, the ordinary fire source in the five ordinary fire flints was completely absorbed, and the five ordinary fire flints immediately turned into ashes and disappeared. The Flame Flint, which had absorbed the source of ordinary fire from five fist-sized ordinary fire flints, had now reached the size of a fist.

Previously, because of the absorption of a soybean-sized evil fire flint, the Flame Flint had reached the size of a fingernail. This time, after absorbing five fist-sized ordinary fire flints, the source of ordinary fire nurtured in them was obviously not pure enough, so after absorbing the source of ordinary fire from the five ordinary fire flints, the Flame Flint only reached the size of a fist. If these five ordinary fire flints could be as pure as the evil fire flint, I'm afraid this time the Flame Flint could at least reach the size of a human head.

Although the color of the fist-sized Flame Flint was still light yellow, it could be seen that there were already more than ten flames flowing faintly in the entire flint. This meant that he had collected at least more than ten different sources of ordinary fire.

However, thinking about the fact that ordinary fire is known as the source of all fires, the gap between more than ten kinds and ten thousand kinds is too big, and Wu Yan couldn't help but laugh and cry. To be honest, he is still not sure about the real purpose of this ordinary fire. Although it is speculated in the Shennong Pharmacopoeia that this fire is a necessary fire for refining the elixir of the ancestor level, this is just speculation, not certain.

Judging from the fire power displayed by this piece of Yanjing Flint, its power is not even comparable to the fire of the immortal cultivators, let alone the spiritual fire and the immortal fire.

Can this kind of fire be used to refine the elixir? Wu Yan was very skeptical.

While thinking about this, he flew down and landed in front of the stone door of the stone room. Wu Yan flipped his palm and took out a fourth-level moon soul stone. Although he felt a little distressed, he still absorbed the soul power in it crazily without hesitation.

After a while, after the soul power of a whole fourth-level moon soul stone was completely absorbed by the Yuan Shen Divine Eye, the vertical eye between Wu Yan's eyebrows finally opened a gap.

Wu Yan aimed the vertical eye at the small stone house without hesitation.

Under the flashing black Yuan Guang, Wu Yan's body was like a ghost. After several flashes, he had opened the stone door of the stone house and entered the stone house.

The most bizarre thing was that although the stone house was covered by the residual power ban of the first-level immortal formation, Wu Yan did not cause any attack from the residual power ban of the immortal formation when he entered the stone house this time, and he did not even touch the residual power ban of the immortal formation.

After entering the stone house, Wu Yan's eyes fell on a small teleportation array in the center of the stone house.

This teleportation array seemed to be a very short-distance teleportation array. Not only did it occupy a small area, but it did not even require high-level spirit stones to open the teleportation array. I am afraid that as long as six high-quality spirit stones were placed, it would be possible to teleport.

Wu Yan did not rashly put in the spirit stones for teleportation, but looked into the depths of the teleportation array with his vertical eyes stretched out. A strange scene appeared!

Wu Yan actually saw the other end of the teleportation array through his vertical eyes! He had never imagined that this vertical-eyed divine eye had the ability to see through short-distance teleportation arrays!
