In the main hall of the Dan Hall, Du Long was not in a hurry to start refining the pills, but sat cross-legged on a futon in the hall, closed his eyes and began to operate the Xuantian Determination Technique to restore the energy consumed by the previous cultivation.

Just restorative cultivation didn't need to put too much attention into it, allowing the energy to travel along the Xuantian Decisive Gong Method transfer route in the body, but Du Long's main energy was on the bottleneck encountered in today's cultivation.

The wind footwork has reached the peak state of the fourth layer of wind waves, and then it is the fifth level of the realm of breaking the sky, and there is also the fact that he has spent nearly a hundred years in the fairy world, but he is still trapped in the sword realm of Xuanyang's nine stacks of waves, and he has not been able to break through the artistic conception of ten stacks of waves!

Since it had just broken through to the Triple Heaven Soul Realm, it would take decades for the soul power in the soul space to reach the Triple Heaven Consummation Limit!

If the soul power cannot reach the Triple Heaven Consummation, it will not be able to break through to the Soul Realm of the Four Heavens, and Du Long will not be able to break through the Chaos Initial Realm and reach the great level of strength of the Qiankun Beginning!

In other words, if Du Long wants the yin and yang energy group in the dantian space to break through to the Qiankun Initiation Stage, he also needs to let the soul power accumulation in the soul space reach the limit of the Triple Heaven Consummation, and this process will take at least ninety years if there is no adventure!

All in all, Du Long's cultivation now encounters two bottlenecks, one requires a long period of accumulation to make a breakthrough, for him, only the breakthrough of these two bottlenecks is the fastest way for his strength to change qualitatively again!

In the blink of an eye, he also had a plan in his heart, knowing that the growth of soul power was extremely difficult, and he could only pin his hopes on those two bottlenecks, hoping to find a way to break through the bottleneck as soon as possible and make his strength qualitatively improve again!

After summarizing his current cultivation situation, Du Long no longer deliberately thought about those complicated things, but continued to exercise to restore the energy in his body, while allowing his head to think about some inconsequential things casually.

Thinking of whether the relatives in the mortal realm are okay now, thinking of the various encounters on the way to participate in the Immortal Realm Pill Competition, and then thinking of the space ring containing immortal medicinal materials that Lu Qingyun gave him in the Medicine King Valley......

'Wait!!'

Du Long, whose mind was gradually entering a state of emptiness, suddenly had a flash of inspiration in his mind when he was halfway through his thoughts, and the whole person suddenly woke up, and the Xuantian Decision that was running also came to an abrupt end!

"Space Ring...... Space Ring!" Du Long kept repeating these four words in his mouth, and for a moment he seemed to be unable to grasp the aura that had just flashed!

As we all know, after waking up from a dream, people often forget what dream they just had, or they can't remember something that feels very important in the dream!

Just like Du Long now, he was just in a state of semi-emptiness, a bit similar to the state between half dreaming and half waking up!

He only remembered that he flashed a spiritual light after thinking of the space ring, although he felt that he was in a state of mid-emptiness, this spiritual light made him feel that this matter was very important to him, but after waking up, he couldn't figure out what important information the space ring would have!

As a powerhouse who had reached the strength of the immortal rank, Du Long knew very well how important this sudden flash of spiritual light was, and he didn't have the heart to continue to recover his skills, but sat cross-legged on the futon, frowning and thinking about what the spiritual light just now meant!

It's a pity that no matter how hard he tries, he can't think of the key point, and he doesn't know how important the space ring, which is not too precious in the two worlds, will have a significant effect on him!

"Ling'er!" After meditating alone for a long time and not coming up with a reason, Du Long could only ask for help from Lingling'er: "Do you know what happened to me just now?!What kind of special effect and significance does the space ring have for me?!"

'Alas!' Ring Spirit Ling'er sighed softly, "Just now you were thinking nonsense, slowly about to enter the realm of the void and the underworld, I didn't pay attention to what you were thinking, through your memories I roughly summed it up, you were thinking about the problem of cultivation bottlenecks before the aura suddenly appeared, and the appearance of aura through an ordinary item is probably related to these two bottlenecks!"

It is worthy of the existence that has existed for an unknown number of years, and the analysis of the Ring Spirit Ling'er made Du Long's originally somewhat confused gaze instantly become extremely bright!

'Space Ring...... Space Ring ...... Space...... I see!hahaha......' After continuing to chant the spatial ring twice, Du Long's eyes instantly became extremely bright, as if he had grasped the spiritual light that flashed in his previous mid-empty underworld.

With bursts of excited laughter, Du Long's figure disappeared out of thin air, and then in the instrument hall next door, his figure flashed in front of the refining table again!

Without any pause, he waved his hand and an ore flew up from the ore pile and landed in his palm!

This ore is not the best ore in the fairy world, it is just a palm-sized ore from the giant blue planet of the mortal world!

Ore is very famous in those spiritual worlds of the fairy world and the mortal world, and it is actually the main material for refining the space ring!

The Space Ring is very rare compared to ordinary mortals, but compared to spiritual or immortal cultivators, it couldn't be simpler!

As an immortal-level powerhouse who has reached the Triple Heaven Realm, Du Long's refining level has long been able to refine the space ring, but compared to him, there are too many space rings, and there is no need to refine them himself!

Disheveled!

As soon as his mind moved, a red flame flashing with dark gold flames appeared in Du Long's palm, instantly enveloping the piece of stone!

This kind of ore that can be refined even by the existence of spirit level strength, in the face of Du Long's seven-star level flame, it is not an exaggeration to describe it as falling into the fire pit with ice cubes, just in the blink of an eye, a palm-sized piece of ore turned into a mass of molten metal, constantly boiling and bubbles in the flames!

In just a few moments, the molten metal no longer bubbles, but was boiling and wriggling there!

With the passage of time, after seeing that the size of the molten metal had shrunk by more than half, Du Long controlled the flame to lower the temperature, and the molten metal, which was originally wriggling violently, gradually became docile, and the frequency of the creeping decreased a lot!

Under Du Long's control, this mass of molten metal began to deform, and soon turned into a round bracelet shape!

Unlike other people refining weapons, they will desperately carve many exquisite patterns on it when they arrive here, Du Long does not carve any graphics on this ring at all, and directly starts to carve formation patterns on it!

This is the most basic formation pattern for refining space rings, also known as space formations, whether it is the fairy world or the mortal world, it is not rare, but Du Long rarely uses it!

After only two failures, there was a successful result of carving the formation pattern, and the so-called success means that the carved space formation can attract the power of heaven and earth!

The entire process of refining the space ring was very easy for Du Long, although he failed to carve the space formation twice, he didn't care, the moment he succeeded for the third time, his whole mind was all invested in the changes in the power of heaven and earth that were triggered after success!

That's right, Du Long just focused all his attention on the moment when the carved formation attracted the power of heaven and earth, this moment was fleeting, and he didn't seem to grasp the answer he wanted!

With only a frown, he immediately controlled the deformation of the ring formed by the condensation of molten metal, and reverted back to a ball of molten metal that was gently wriggling!

Then condense and transform into a ring again, and then continue to carve the space formation pattern on it, and then at the moment when the power of heaven and earth is triggered, he will concentrate all his attention and find the answer he wants from the fluctuations of the power of heaven and earth!

The result was still a failure, the moment when the power of heaven and earth was triggered was too short, Du Long faintly grasped something, but he couldn't fully grasp most of the information that flashed away.

He didn't hesitate to repeat the process just now, twice...... Three times......

Time passed, and the molten metal was still evaporating and shrinking at an extremely slow rate under the scorching flames that could only keep it liquefied!

With the passage of time, even if the flame intensity required to refine the stone molten metal was not high, it could not withstand the consumption for a long time, and I don't know how many times after repeating that process like this, the chaotic immortal fire in Du Long's body was finally consumed.

Repeating the same operation with such intensity, it is not an exaggeration to describe Du Long as exhausted!

It seems to be a simple process, but it is necessary to concentrate on the moment when the power of heaven and earth is attracted at all times, and during this period, it is necessary to constantly maintain the flame temperature and scorch the molten metal, which is definitely a matter of both energy consumption and exhaustion!

Call!

After exhaling a long breath of turbidity, Du Long flashed to a futon next to the refining platform, sat down directly on it, and began to exercise to recover the flame energy he had consumed!

In order to recover the huge loss of spiritual power by the way, he naturally has to enter the empty state of nothing and selflessness, and only this state similar to deep sleep is the best way to recover his spiritual power!

After about a day and a night, Du Long, who had regained his peak condition, once again began the process that seemed meaningless to outsiders, refining ore, condensing the molten metal ring, and carving a spatial circle on it!

After successfully attracting the power of heaven and earth, it immediately dispersed the molten metal ring, and then formed it again, carving the space circle and then attracting the power of heaven and earth, and so on......

Jieling Ling'er, who originally felt a little confused by Du Long's move, was dumbfounded on the spot when she figured out why this kid was doing such a seemingly useless thing!

'Genius! Sure enough, he is the genius of the sword-shaped primordial god! I can even think of this method, this ...... This is also incredible, isn't it?!' In the space of the Dragon Venerable Ring, a low murmur that Du Long couldn't hear.
