In the small cave, Du Long sat helplessly on the stone platform, frowning and staring at the spatial cracks that flashed outside the cave from time to time, and whispered softly: "Nine years have passed, can those three guys eat enough and have nothing to do?!

"Hehe, nine years is nothing to these immortal cultivators who have lived for hundreds of millions of years!" replied with a smile.

"How is this good?!If those three guys want to stay at the entrance of the cave, will it be possible that I will shrink into this small cave forever?!" The soul strength has reached the Five Heavens Perfection Realm, and Du Long is in the bottleneck stage in terms of cultivation, and he doesn't know how to pass this boring time at all.

"It's very simple!, or enter the Xuanling Small Cave Heaven World to meet your confidantes, or continue to cultivate the Perception Space here!"

"Feel the space?!" Du Long replied in confusion.

Ring Spirit Ling'er said with some hatred: "Nonsense! I think at the beginning, you successfully used the refining of the primary space ring to understand the mysteries of the primary space, and now, your soul realm has reached the fivefold heaven perfection realm, it's time to start refining the intermediate space ring, and then take the opportunity to comprehend the mysteries of the intermediate space!"

"Comprehend the mysteries of intermediate space?!" Du Long's eyes suddenly lit up, blooming with dazzling light.

After he first comprehended the mysteries of the primary space, he had been unable to comprehend the mysteries of the higher-level space because the soul realm was too low, which made him feel depressed for a long time!

He really didn't expect that the opportunity to practice the mysteries of the intermediate space would come so quickly, how could this not surprise him?!

He was not in a hurry to start cultivating immediately, and Du Long, who had been ignoring the fact that he had thrown the girls in the Cave Heaven World for nine years, disappeared without a trace, and had already entered the Xuanling Small Cave Heaven World!

In a corner of the back garden of Xuanling Palace, two little girls with pink makeup were playing in the garden, and a delicate figure sat on the stone chair next to them, holding a book in her right hand, but her eyes were not on the book, but she looked at the two little girls in the garden playing and frolicking there!

These two little girls are none other than Hua Xiang'er, the little princess from the Flower Fairy Spirit Clan, and the other is Ga Qing, the little princess from the Fire Ape Demon Clan!

Of course, the two of them are not royal princesses in the strict sense, but just the tribal patriarch has a thousand gold!

These two little princesses have a similar experience, because of their naughty willfulness, the black killing will discover the secret stronghold of the tribe's seclusion, and in the end, it almost affected the clansmen!

The most beloved Hua Xiang'er's own uncle Hua Wuming fell because of this, Ga Qing's mother used the secret method of the fire ape demon clan and finally fell, the two little girls blamed themselves for this for many years, and recently finally came out of the pain of losing their loved ones.

For many years, Du Long has been in retreat and penance, in addition to cultivation, Du Lian'er will stay with these two little girls in her spare time, and this is the case today, looking at the two little sisters who have regained their innocence, Du Lian'er has a faint smile on her face.

Airplanes!

With a flash of golden light, she saw a figure suddenly appear in front of her, Du Lian'er was stunned and shifted her gaze from the two little girls to the person who came, after seeing his appearance clearly, she who had always been as elegant as a fairy couldn't help but be surprised and screamed Daddy, and then dodged into Du Long's arms.

Gently hugging his beloved daughter's thin waist with a smile, Du Long reached out and patted her shoulder dotingly: "Haha, let Daddy take a closer look, it's only been a few years, my baby daughter has become beautiful again!"

"Daddy!" Du Lian'er showed the shy posture of her little daughter, and stomped on her lotus feet and said in a coquettish voice: "How did Daddy retreat and practice for so many years this time? !

"Hehe, no wonder I didn't see them in the three cave worlds, so it's no wonder that my father neglected a few of them in his long-term cultivation!" Du Long shook his head helplessly and chuckled.

"Daddy's words are serious, if it weren't for Daddy's desperate hard cultivation outside, how could we have such a peaceful and leisurely life?! It's Daddy who has been fighting hard outside for many years!" Du Lian'er obediently excused Du Long.

"Haha! Daddy is the head of the family, and the bloody fight outside naturally has to be borne by one force! Lian'er, who has been stuffed in the cave world in recent years, will she feel too bored?!"

"Lian'er doesn't feel bored, in addition to cultivating, she can also wander around the newly built town of the Flower Fairy Spirit Clan and the Fire Ape Demon Clan in Qinglang Cave in her spare time, and Xiang'er and Qing'er accompany you, life is very comfortable and freehand, Daddy doesn't need to worry about me in the outside world, just take care of your body!" Du Lian'er responded obediently again.

"Haha, Lian'er is really Daddy's most intimate little padded jacket!" Du Long replied with a smile of relief.

"Xiang'er (Qing'er) has seen Uncle Du Long!" The two little girls who had stopped frolicking a long time ago only then opened their mouths to say goodbye, Du Long let go of the baby daughter, stepped forward with a smile and hugged the two little girls with pink makeup at the same time, and said with a little surprise: "I haven't seen each other for a few years, why haven't we seen Xiang'er and Qing'er grow much taller?!!, or two little girls?!"

The two little girls were blushing by his shock, and Ga Qing said coquettishly: "Uncle Dulong...... You're comparing us to Terran children again?!"

Du Long was stunned for a moment, and then suddenly realized: "Haha! Yes, the growth rate of the demon clan children is relatively slow, looking at the memory of the uncle, he actually forgot this stubble!"

In the garden, Du Long chatted with the three little girls like this, facing him who was approachable and didn't have the slightest, Hua Xiang'er and Ga Qing easily got along with him, and didn't regard him as the master of these cave worlds and the savior of his two tribes!

Afterwards, Du Long explained to Du Lian'er again, telling her that he was going out for a long time to retreat this time, and asked her to tell Qin Huofeng's daughters, so he said goodbye to the third daughter, and went back to the small cave to retreat and practice!

Facing the spatial rift that flashed in the sky, Du Long sacrificed Huoyun Ding in the cave, got out the ore materials for refining the medium-grade space ring, and then began to repeat the penance of refining the medium-grade space ring!

Condensed the ring-type ordinary space ring again and again, and then engraved the intermediate space circle on it, and then attracted the power of heaven and earth to resonate, and after successfully refining the medium-grade space ring, it was immediately returned to the furnace for re-refining!

Refining a medium-grade space ring is not his primary purpose, at the moment of attracting the power of heaven and earth, it is the key to comprehend the mysteries of space that flash away!

Time passed slowly, and this time, the cultivation progress of comprehending the changes in the power of heaven and earth from refining the medium-grade space ring, and then comprehending the mysteries of space, was not very smooth!

Each time you raise a level of heaven and earth mysteries, the difficulty of cultivation doubles, and if you want to comprehend the mysteries of the huge intermediate space at the moment of attracting the power of heaven and earth, its difficulty will increase geometrically!

It was precisely because it was too difficult that Ring Spirit Ling'er would let him wait until his soul strength had improved to a certain level before he comprehended the mysteries of cultivating the intermediate space, instead of immediately cultivating the mysteries of the higher level of the space after he had successfully mastered the mysteries of the primary space!

Time passed day by day, one nine years passed, Du Long was still cultivating in the cave, two nine years had passed, but he was still the same, no one knew how long it would take him to cultivate this time!

In the blink of an eye, it was already the ninth ninth year, and Du Long had actually spent more than seventy years in this small cave, in order to cultivate and comprehend the mysteries of the intermediate space!

Call!

One day in the seventy-eighth year, Du Long, who had been cultivating for many years, finally stopped, and while opening his eyes, he exhaled a long breath of turbidity, and a blazing light flashed in his eyes!

"After seventy-eight years, I have finally approached the consummation of the intermediate spatial mysteries, but how can I break through this consummation in the end?!" his eyes blazing as he looked at the spatial cracks that flashed outside the cave from time to time, and Du Long muttered softly in his mouth.

This time, the Ring Spirit Ling'er, who had been silent for more than seventy years, did not speak, regarding the cultivation of the mysteries of heaven and earth, she could only provide some cultivation directions at most, but she did not have any practical experience to tell Du Long, this aspect will always be the shortcoming of their kind of life!

"Intermediate Spatial Mystery......" Du Long secretly evolved his cultivation achievements in the past seventy-eight years in his heart, muttering something softly, but his eyes fell on the spatial cracks that kept flashing outside the cave!

Boom, boom, boom......

The originally silent space, because of the constantly flashing spatial cracks, there was a light sound like tearing jade silk, and the strange sound of the space being torn apart by irresistible force continued to resound in this space!

Swish!

Among the many spatial rifts, a huge spatial rift that was more than ten times larger than the usual spatial rift suddenly appeared, just like a big fish eating a small fish, where the huge spatial rift passed, those small spatial rifts were instantly swallowed and assimilated, and the size of the huge spatial rift also increased by one point!

Looking at the huge spatial rift in front of him, looking at the moment when it fused with each other when it devoured other small spatial rifts, the scene where the power of countless heaven and earth gushed and merged, Du Long's originally puzzled eyes lit up, and an irrepressible smile of excitement appeared on his face!

"Haha, I see! I see, I see!" After laughing excitedly, Du Long's whole person disappeared from the cave in an instant, and when he reappeared, he had already come to the sky above the lava river outside!

Boom, boom, boom......

The spatial cracks in the sky flashed one after another, and in the cracks of these spatial cracks, a figure kept flashing like a ghost!

It was as if he could sense the location of the spatial rift, and Du Long actually dared to use the ability of teleportation unscrupulously in such a dangerous environment!

In addition, the spatial fluctuations generated by his teleportation were many times more subtle than before, if it weren't for the existence of a particularly powerful being, his immortal sense might not be able to detect the spatial fluctuations caused by this teleportation, and even if he did, he would be mistaken for a normal spatial fold, right?!
