When the demon bear figure disappeared into the cave, Lu Yan took a long breath, and then looked down at the ground around him. In the end, Lu Yan still walked to the place where he dug the spirit mine last time.

Ever since I absorbed the purple qi on the cliff in the morning, I had a faint feeling that the breath of the dantian was about to be suppressed. That's why I went to the stone pile to practice, and I vented by the way. However, after taking a bath just now, the aura riot became more and more obvious, so I decided to break through on the spot.

However, this time the breakthrough momentum is obviously much stronger than the previous one, and the breakthrough process is bound to require a huge aura. So Lu Yan thought of the pit where he had dug the spirit mine before.

After a certain amount of heart, Lu Yan waved his hand and shot a strong aura towards the new place.

"Boom"

The energy blew the place into a large crater about a meter deep. Lu Yan struck several more energetic qi one after another, and did not stop until the big pit was about a foot deep.

After adjusting his breath slightly, Lu Yan jumped towards the deep pit.

After arriving below, Lu Yan took out a futon mat that he had roughly made before from the space ring and put it on the ground, and then Lu Yan sat cross-legged on it.

After closing his eyes slightly, Lu Yan let his whole body relax, and he was not deliberately suppressing the riot of the aura in the dantian, but letting it be completely in a natural state.

When Lu Yan let the dantian be in its natural state, the trend of the riot suddenly became very strong, but it did not immediately enter the threshold of breakthrough. Under Lu Yan's perception, the thin film seemed to be constantly expanding, but it just didn't break through. Seeing this, Lu Yan did not panic, but his mind moved, and two more medium-grade spirit stones appeared in his hands, and a powerful suction force continuously absorbed the energy on the spirit stones into his body from the palm of his hand.

The pure energy entered the body, and the true qi in the dantian immediately boiled, and the strong feeling of swelling and pain came instantly. Lu Yan only felt as if the meridians of his whole body were being pulled, and his whole face was hideous. gritted his teeth and endured this grinding pain, constantly guiding the aura into his body.

Soon, the spirit stone in Lu Yan's hand turned into gray-white powder, but the blocking film was still not pierced.

Lu Yan began to feel a little anxious in his heart, but after all, he was a person who had experienced life and death. Soon, with his strong will, he quickly regained his composure, and then took out two medium-grade spirit stones from the space ring, and accelerated the speed of absorbing spiritual energy with strong means.

Soon, the spirit stone in his hand turned into powder again, but the imaginary breakthrough still did not come.

Lu Yan no longer hesitated at the moment, gritted his teeth and directly took out dozens of spirit stones from the space ring and put them in front of him, and then a powerful suction force penetrated through his body, directly absorbing and refining the energy of dozens of spirit stones at the same time.

This was a crazy move, absorbing so much spirit stone energy at the same time, even a martial artist of the Houtian Realm would not dare to do so. After all, the energy contained in so many spirit stones has greatly exceeded the energy contained in the master of the Acquired Realm himself, if he forcibly absorbs it, the final outcome will definitely be to explode and die!

But now Lu Yan couldn't care about it so much, because he felt that after the energy of the four spirit stones he had absorbed just now entered his body, he couldn't make a single wave when he arrived at the dantian, like a cow sinking into the sea. For a moment, Lu Yan wondered if the rebellion of Dantian True Qi was a precursor to a breakthrough. But he has been cultivating for so many years, after all, he has also experienced many breakthroughs, and he still has a little understanding of the precursors of breakthroughs.

In the end, Lu Yan could only understand this abnormal situation as his dantian, which had become more able to accommodate more aura than ordinary people after the restoration of the evergreen true qi!

Therefore, Lu Yan simply gave him a chance and directly took out dozens of spirit stones from the space ring at one time, and he also wanted to see how much energy his dantian could store now.

Soon, under Lu Yan's frantic absorption, streams of thick energy were peeled off from the spirit stone, and then gathered around Lu Yan's body, burrowing into his body from the skin.

As this huge stream of pure energy continued to enter his body, the muscles of Lu Yan's whole body were constantly bulging, and the aura on his body became more and more powerful, even stirring up a whirlwind around his body. Lu Yan's long black hair continued to fly with the whirlwind, and the bangs on his forehead were also blown up!

However, Lu Yan didn't have time to take care of these, he had now gradually felt that the dantian was beginning to gradually show a little change, but it was still very slow. But this has already surprised him, as long as there is a change, it proves that there is a play.

Just when this was Lu Yan's mind, a bright light suddenly flashed, and then an extra red crystal bead appeared in Lu Yan's hand, which was the demon crystal of the Fire Crystal Winged Lion!

Just now, Lu Yan thought that he was cultivating the Heavenly Flame Technique, and if he absorbed the fire attribute aura, the rhythm of this breakthrough would definitely be faster, and then he thought of the demon crystal of the Fire Crystal Winged Lion in the Space Ring.

When the red crystal bead appeared, the true qi in Lu Yan's body was violently agitated, and Lu Yan was overjoyed in his heart. Immediately, Lu Yan stopped absorbing the pile of spirit stones in front of him, and instead focused on absorbing the demon crystals of the Refining Fire Crystal Winged Lion.

When the first wisp of demon crystal energy entered his body, a mutation occurred! Lu Yan only felt a violent and bloodthirsty thought rise in his mind.

Lu Yan's face changed drastically, he didn't expect that the energy of this demon crystal would have the ferocity of the Fire Crystal Winged Lion!

However, when Lu Yan reacted, he immediately suppressed this violent and bloodthirsty thought with his strong spiritual power and willpower. However, he did not stop refining and absorbing the demon crystal, but while absorbing it, he urged the evergreen true qi of the lower dantian to travel around his whole body to suddenly practice the absorbed demon crystal energy, and then guide it to the upper dantian to become a part of the fire flame true qi.

Sure enough, the evergreen true qi could indeed suddenly practice these violent demon crystal energy, and when the first wisp of refined demon crystal energy entered the dantian, Lu Yan could no longer feel that violent and bloodthirsty thought.

With joy in his heart, Lu Yan even accelerated the speed of refining and absorption. And the fire flame true qi in the dantian is indeed easier to fuse these true qi, and Lu Yan has become more and more clearly aware that he has entered the critical point of breakthrough.

Time passed unconsciously, nearly half an hour passed, and Lu Yan's forehead was already covered with fine beads of sweat at this time, his face was flushed, and there were bursts of heat on the top of his head. At this time, he has entered the last critical moment!

"Po"

At this moment, a sound suddenly sounded in Lu Yan's ears, so crisp and loud.

Immediately after that, a loud "boom" broke out, and a powerful momentum suddenly erupted from Lu Yan's body, rushing straight into the sky, bringing a hurricane, blowing the spirit grass and spirit flower above to squeak.

Lu Yan didn't have time to think before he immediately threw himself into the breakthrough, and a more powerful suction force spread from his body to the surroundings, constantly pulling the aura in the surrounding air. And the spirit stones that had not been refined and absorbed before also turned into a puddle of powder in an instant, and all the energy was absorbed into Lu Yan's body.

Even Lu Yan vaguely felt that a majestic energy was surging up from the ground, forming a layer of spiritual mist around Lu Yan's body, and then continuously entering Lu Yan's body.

The red crystal ball in Lu Yan's dantian also rotated, and the color of the surface became darker and darker. After the energy that came in entered the dantian, it was fed back and constantly washed away Lu Yan's body.

At this time, Lu Yan's aura was growing at a violent rate.

Nine Layers of Qi Training....... The pinnacle of Qi training.... The first floor of the acquired realm... The middle stage of the first layer of the acquired realm.. At the peak of the first layer of the Acquired Realm, that strong aura grew until the beginning of the second layer of the Acquired Realm before it began to gradually weaken.

After another quarter of an hour, Lu Yan felt that the growth of his strength had become very slow.

Lu Yan opened his eyes slightly, and a red light shot out of his eyes, more than a foot long. As Lu Yan completed the breakthrough, he also stopped absorbing the surrounding aura, and those mist-turning auras gradually dissipated into the air.

"Is this the strength of the Acquired Realm? It's really different!" Lu Yan felt the surging power in his body, and a smile bloomed on his face. He secretly estimated that his current strength should be more than ten times stronger than before the breakthrough, which surprised him.

At this time, the red demon crystal in the palm of his hand had not been absorbed, but it was less than one-tenth the size of before.
