Chapter 938

"Refining space rifts into mustard spaces? This heaven-defying secret technique has already appeared in the world." Han Li's face showed a faint look of shock, and he said somewhat incredulously.

Anything involving spatial secret techniques is earth-shattering and of great significance. Speaking of which, the most common magic tool in the cultivation world, the storage bag, is actually one of the most common applications of spatial secret techniques. It's just that no matter how high the tier of the storage bag is, the things it can hold are limited, and it cannot be called a true mustard space at all.

Many cultivators even believe that higher-tier spatial secret techniques cannot appear in the mortal world at all and should be supernatural powers that only immortal world cultivators have the ability to display. This kind of saying is almost an accepted fact in Tiannan.

But now, hearing Elder Wang's words, the Great Jin actually had a secret technique for refining space rifts more than a thousand years ago. How could Han Li not be greatly shocked?

"Brother Han, you don't need to be so surprised. This so-called 'mustard space' is not as profound as you think, and its appearance is just a coincidence." The old man surnamed Fu suddenly smiled and said.

"Brother Fu is right. For most people, the mustard space is actually a chicken-rib existence. Not only is it extremely difficult to refine, but its use is also limited. It cannot be promoted and applied at all. Speaking of which, there are only a dozen such mustard spaces in the entire Great Jin, and the one in our pavilion is the earliest one to appear." Elder Wang also smiled bitterly and said.

"The earliest? Could it be..." Han Li's eyebrows moved, feeling somewhat suspicious.

"That's right, this secret technique was actually created by several artifact refining masters of our pavilion unintentionally. In the world, only two artifact refining masters of our pavilion can refine this kind of mustard space. In fact, the Heavenly Mystery House and Heavenly Mystery Mansion, in a sense, are also secret techniques researched separately based on this mustard space refining technique." Elder Wang did not intend to hide anything and actually told everything one by one.

"Hehe, so that's how it is. I really want to see the magic of this mustard space." Han Li recovered his composure, smiled, and said.

"Brother Wang, take Fellow Daoist Han there. I have been to that mustard space, so I won't go. I still need to deal with this Red Essence Ganoderma, so I will take my leave from you two fellow Daoists first." The old man surnamed Fu cupped his hands and said goodbye to the two with a solemn face.

"Since Brother Fu has other important matters, I won't keep you. See you another day, Brother Fu." Elder Wang cupped his hands in a salute.

And Han Li's ears heard a few words of exhortation from the old man, telling him not to miss the last day of the underground trading assembly. Han Li naturally nodded to the other party inadvertently.

Then the old man did not hesitate to walk out of the hall and thumped down the stairs.

"Brother Han, let's go too. The mustard space is behind the pavilion, and we will be there in a blink of an eye." Elder Wang then turned around and said to Han Li with a smile, then brushed his sleeve across the table inadvertently, and the larger jade box immediately disappeared from the table.

Han Li naturally would not refuse and immediately followed Elder Wang through a layer of strict restrictions to a small open space behind the pavilion. In the middle of this open space, there was a strange teleportation array that Han Li had never seen before.

It was obviously much more complicated than an ordinary teleportation array and was also a circle larger.

Han Li frowned slightly, feeling somewhat surprised.

"To go to the mustard space, one can only reach it from this teleportation array." Seeming to see Han Li's confusion, Elder Wang explained.

"Need to use a teleportation array? Could it be that this refined space rift is fixed in a certain place?" Han Li's mouth moved, feeling secretly surprised inwardly. But he couldn't ask directly about such matters involving refining secret techniques. When he saw the other party walk into the teleportation array first, he hesitated slightly and followed him in.

Only then did he discover that the seven or eight spirit stones around the teleportation array were all mid-tier spirit stones. Not to mention anything else, just entering the mustard space would cost seven or eight hundred low-tier spirit stones. If one needed to teleport back, a round trip would cost more than a thousand spirit stones. This expense was really not something an ordinary cultivator could afford.

Just as Han Li was thinking, white light surged from the spirit stones around the teleportation array, and the two disappeared in a flash.

After a dizzying spell, Han Li and the other appeared on a gravel slope, with a teleportation array similar to the one they had teleported in from under their feet.

Han Li steadied himself and raised his head to look around.

Looking at it, a space of over a thousand zhang appeared in front of him. The ground was full of white stones, but it was covered with many stone pits of different sizes, the large ones being over ten zhang and the small ones only a zhang or so, distributed in a chaotic manner.

Han Li took a deep breath and muttered inwardly. Not only was there no green color in this space, but he also didn't sense the existence of spiritual energy. The sky looked gray, clearly a place of death.

"Brother Han should be able to see that this space is actually a place of death. After all, it is one in ten thousand that a space rift can naturally contain a spiritual vein. As for finding the legendary holy land like the Spirit Garden where the spiritual energy is even better than the mortal world, it is even more impossible to think about. Since our Great Jin cultivation world discovered space rifts, only three or four places with slightly spiritual energy and spiritual veins have been discovered, and they are far less dense than the spiritual energy of the mortal world. But even for these space rifts, the sects that discovered them have successively asked our pavilion to assist them in refining them into mustard spaces." After walking out of the teleportation array, Elder Wang smiled and said to Han Li.

"So, besides being able to save some space and being able to enter and exit freely, this mustard space seems to have no special use. No wonder I have never heard anyone mention the mustard space since I arrived here." Han Li rubbed his chin and said with a strange expression.

"That cannot be said either. If some sects want to store some large secret items, store a large amount of materials, or simply build a secret room to hide when encountering enemies, these mustard spaces are the best choice. Even like our Heavenly Mystery Pavilion, it is not bad to use it as a trial space for magic tools and treasures. The reason why mustard spaces are rare is that suitable space rifts are really not easy to find. There are not many space rifts in the world whose accurate locations are known, and among them, there are even fewer whose locations are suitable and only known to some sects. Plus, the cost of materials for refining such a mustard space is truly astonishing. These many reasons combined have caused the mustard spaces to be so few." Elder Wang was somewhat embarrassed and explained hurriedly.

"Even so. This kind of mustard space of your pavilion is too far from the idea of being able to manipulate it at will or even carry it with me that I originally imagined. Entering and exiting actually requires setting up a teleportation array. This really cannot be called a Sumeru mustard." Han Li sighed and said somewhat regretfully.

"Hehe, to be able to carry such a large space with you, perhaps only those with great supernatural powers who have ascended to the Spirit World or true immortals of the Immortal World have this ability. In our mortal world, there is absolutely no such heaven-defying ability. Being able to borrow a large amount of rare materials to stabilize and fix the existing space rifts is already an amazing breakthrough." Elder Wang, however, disagreed.

"Can stabilize space? Could it be that space rifts that are about to collapse can also be reinforced?" Han Li felt a great shock in his heart, and his gaze flashed rapidly.

"This is naturally possible, as long as the space rift has not truly collapsed, we can use materials to stabilize this space again. What, Fellow Daoist Han also knows of such a rift?" The silver-robed cultivator's expression moved, and he asked somewhat surprised.

"Hehe, I did discover such a rift somewhere overseas. As for whether it has collapsed, I don't have the ability to enter it, so I don't know. I just feel that the entrance is somewhat unstable." Han Li then smiled and said vaguely.

The silver-robed cultivator naturally saw that Han Li didn't want to mention more about this matter, so he naturally wouldn't be tactless and ask more, but flipped his palm, and the jade box containing the Heavenly Mystery Mansion appeared in his hand.

"I will release this Heavenly Mystery Mansion now, and you can enter the mansion to see if you are satisfied with the settings inside, Fellow Daoist. If you feel it is okay, we will discuss the transaction of this item." Elder Wang said with a smile.

"Good, please proceed, Fellow Daoist Wang." Han Li nodded and replied.

Seeing Han Li say so, the silver-robed cultivator did not hesitate, reached out to grab and open the jade box, revealing a piece of milky-white spiritual light, vaguely looking like something inside.

Before Han Li could see clearly what was in the box, Elder Wang muttered words, shook the jade box lightly, and suddenly a cluster of white light shot out from the jade box. After a spin, it expanded wildly in the wind and turned into a large cluster of white clouds several mu in size in the air, inside which white jade buildings and pavilions were vaguely visible.

Elder Wang pinched the formula with both hands, gave a low shout, and pointed at the air. After a low hum, the white clouds suddenly fell to the ground.

After a loud "rumble" sound, amidst ten thousand rays of spiritual light, a complete cave abode built entirely of beautiful jade appeared on the open space below the hillside.

Han Li narrowed his eyes and sized it up carefully with his hands behind his back.

This cave abode, which looked extremely exquisite, was obviously a size smaller than ordinary cave abodes. However, it had everything from pavilions and courtyards, and its surface was covered by a layer of white light curtain, making it even more ethereal and dreamy like an immortal's villa.

After gazing for a moment, Han Li's figure flickered and turned into a green rainbow, shooting toward it.

Seeing this, Elder Wang hurriedly flipped his palm, and a white jade token appeared in his hand. After shaking the token at the cave abode below a few times, the light curtain outside the cave abode suddenly disappeared and collapsed, and the green rainbow transformed by Han Li shot into the gate of the cave abode without any obstruction, and his figure disappeared for a time.
