"Refining the spatial rift into a mustard seed space? The look of shock on Han Li's face was faintly visible, and he said with some disbelief.

Anything that involves the secret art of space, which one is not earth-shattering, is of great significance. Speaking of which, the most common magic weapon storage bag in the immortal cultivation world is actually one of the most common applications of space secret arts. It's just that no matter how high the level of the storage bag is, the things that can be accommodated are limited, and it can't be called mustard seed space in the real sense at all.

Even many monks thought that it was impossible for higher-level spatial secret techniques to appear in the human world, and it was completely necessary for the monks of the upper realm to have the ability to perform magical powers. This statement is almost a default thing in Tiannan.

But now, when he heard Elder Wang's words, the Great Jin Dynasty had already appeared more than a thousand years ago with the refining secret technique of the spatial rift, how could it not surprise Han Li.

"Brother Han doesn't need to be so surprised. This so-called 'mustard seed space' is not as advanced as you think, and its appearance is just a coincidence. The rich old man suddenly said with a smile.

"The rich guy is right. In fact, for most people, the mustard seed space is simply a chicken-like existence. Not only is it extremely difficult to refine, but it is also very restrictive to use. You can't promote the app at all. Speaking of which, this kind of mustard seed space is only a dozen places in the entire Great Jin, but here in this pavilion is the first mustard seed space to appear. Elder Wang also said with a wry smile.

"The earliest. Could it be ......" Han Li's eyebrows moved, a little surprised. "That's right, this kind of secret technique was actually created by a few alchemists in this pavilion by accident. There are only two refining masters in the world who can refine this kind of mustard seed space. In fact, in a sense, the Heavenly Machine House and the Heavenly Machine Mansion were also secret techniques that were studied separately based on this mustard space alchemy technique. Elder Wang didn't mean to hide it, and even said it all.

"Hey, I see. I really want to see the magic of this mustard seed space. Han Li regained his composure and said with a smile.

"Brother Wang take Han Daoyou to go, the old man has been to the mustard seed space, so he won't go.

This red essence mushroom has to be processed first. I said goodbye to the two Taoist friends first. The rich old man clenched his fists at this time. The two of them said goodbye.

"Since the rich brother has other important matters. Wang didn't keep much. See you another day. Elder Wang bowed his hand.

However, there were a few words of exhortation in Han Li's ears. Let him not miss the last day of trading at the underground fair. Han Li naturally nodded at the other party inadvertently.

Then the old man walked out of the hall without hesitation. Wow went downstairs.

"Brother Han. Let's go too. The mustard space is just behind the loft lot. In the blink of an eye, it was to the ground. Only then did Elder Wang turn around. Chong Han Li said with a smile. Then the sleeve robe was casually flicked on the table. The larger jade box immediately disappeared from the table.

Naturally, Han Li would not refuse. Immediately followed Elder Wang through a strict prohibition. Got to a small open space behind the attic. In the middle of the open space here. There was a strange teleportation array that Han Li had never seen before.

It's obviously much more complicated than the ordinary Tsumatsu Formation, and it's also a big circle.

Han Li's brows furrowed slightly, a little surprised.

"If you want to go to the mustard space, you can only get there from this teleportation array. As if he could see that Han Li was puzzled, Elder Wang explained.

"Do you want to use a teleportation array? Could it be that this refined spatial rift is fixed somewhere. The corners of Han Li's mouth moved, and he was secretly surprised in his heart. But this kind of thing that obviously involves refining secret arts, he didn't want to ask directly, and when he saw that Fu had walked into the teleportation array first, he followed with a little hesitation.

At this time, he realized that the seven or eight spirit stones around the teleportation array were all middle-grade spirit stones, not to mention anything else, just entering the mustard seed space would cost seven or eight hundred low-grade spirit stones. If you also need to teleport out when you come back, it will cost more than a thousand spirit stones for this round trip, and this cost is really not the energy consumption of ordinary monks.

Just as Han Li was thinking about it, the white light of the spirit stones around the teleportation array suddenly rose, and the two of them disappeared in the teleportation array.

After a dizzying and dizzy moment, Han Li and the others appeared on a gravel slope, and below them was a teleportation array similar to the one that had been teleported in.

Han Li froze and looked around.

At a glance, a space of more than 1,000 zhang appeared in front of me, the ground was full of white stones, but there were many stone pits of different sizes, the big ones were more than ten zhang, and the small ones were only zhang xu, and they were very messy.

Han Li took a deep breath and muttered something in his heart. Not only is there no trace of green in this space, but there is no aura sensed, and the sky looks gray, which is clearly a place of execution.

"Brother Han should have seen that this space is actually a dead one

The spatial crack can naturally contain spiritual veins, but there is no one in ten thousand, and it is even more difficult to think about it to the holy place where the aura of the Lingyu Garden is rumored to be better than that of the human world. Since our Great Jin cultivated the current space crack in the immortal realm, there were only three or four places where there was a little bit of spiritual energy contained in the spiritual vein, and it was even far less dense than the spiritual energy in the human realm. But it was these spatial cracks, and those current sects had successively begged the Pavilion to assist them in refining into mustard seed space. After Elder Wang walked out of the teleportation array, he smiled and said to Han Li.

"In this way, this mustard space doesn't seem to be of much use other than saving some space and allowing you to enter and exit freely. It's no wonder I've been here for so long, and I've never heard anyone talk about the mustard seed space. Han Li touched his chin and said with a strange expression.

The same cannot be said of this. If some sects want to store some large hidden things, store a large amount of materials, or simply create a secret room to hide from enemies, these mustard seed spaces are still the best choice. Even like our Tianji Pavilion, a trial space used as a magic weapon is also good. The reason why mustard seed space is scarce is that it is still a suitable space crack is really not easy to find. There are not many spatial cracks in the world that know the exact location, and there are even fewer of them that are in the right location and only some sects know the secrets. Coupled with the space for refining this mustard seed, the cost of materials is really staggering. The combination of these reasons makes the mustard seed space so small. Elder Wang was a little embarrassed, and quickly explained.

"Even so. This mustard seed space in your pavilion is really far from the idea that you can manipulate it at will and even carry it with you. In and out, there is even a teleportation array. This is really not much about Sumeru mustard seeds. Han Li sighed and said with some pity.

"Hehe, to be able to carry such a large space with you, probably only the great divine power of the Ascending Spirit Realm or the true immortal of the Immortal Realm have this ability. In our human world, it is absolutely impossible to have this ability to defy the sky. Being able to borrow a large number of rare materials to stabilize the existing spatial cracks is a remarkable breakthrough. Elder Wang disagreed.

"Can the space be stabilized, can the space crack that is about to collapse be re-strengthened?" Han Li's heart shook violently, and his eyes flashed a few times.

"This is natural, as long as the crack in the space hasn't really collapsed, we can use materials to stabilize the space again.

Why, Han Daoyou also knows about such a crack?" the silver-robed monk's expression moved, and he asked with some surprise.

"Hehe, Han is in such a crack somewhere overseas. As for whether the block has collapsed, I don't have the ability to get in yet, but I don't know. I just feel that the entrance is a little unstable. Han Li immediately smiled and said vaguely.

The silver-robed monk naturally saw that Han Li didn't want to mention this matter more, and of course he didn't want to ask anything more without interest, but as soon as he flipped his palm, the jade box containing the Heavenly Machine Mansion appeared in his hand.

Wang will release this Tianji Mansion, and Daoyou can enter the mansion to see if you are satisfied with the settings inside. If you think it's okay, we'll negotiate a deal about it. Elder Wang said with a smile.

"Okay, Wang Daoyou, just cast a spell. Han Li nodded and replied.

Seeing Han Li say this, the silver-robed monk no longer hesitated, and reached out to open the jade box, revealing a milky white aura inside, faintly looking like something was there.

Before Han Li could see the contents of the box clearly, Elder Wang said something in his mouth, shook the jade box slightly, and suddenly a ball of white light flew out from the jade box, and in the blink of an eye, it swelled wildly in the wind, and after a circle, it turned into a large cloud of white glow in the air that was several acres in size, and there were faint houses and pavilions and other white jade carved buildings looming inside.

Elder Wang pinched the trick with both hands, and with a low cry in his mouth, he pointed a little into the air, and after a low hum, Bai Xia suddenly fell to the ground.

After a loud "boom", in the spiritual light, a complete cave mansion made of beautiful jade appeared in the open space under the hillside.

Han Li's eyes were microns, and he looked at them carefully with his hands upside down.

This exquisite-looking cave house is obviously one size smaller than the ordinary cave house. However, the pavilions and courtyards are all complete, and the surface is also shrouded by a layer of white light curtain, which makes it like a fairy courtyard.

After staring at it for a moment, Han Li's figure flickered, and he suddenly turned into a blue rainbow and shot away.

Seeing this, Elder Wang hurriedly flipped his palm, and a white jade token appeared in his hand, and after shaking it lightly with this token at the cave mansion below, the light curtain outside the cave mansion suddenly disappeared and collapsed, and Han Li's blue rainbow shot into the gate of the cave mansion without hindrance, and his figure disappeared for a while.
