Song Wei showed a hint of joy when she heard this, and said happily: "Great! Ruofei, then we should continue to cultivate, right? Why did you suddenly stop?"

Xia Ruofei scratched his head and said, "I feel that the 'Taichu Heart Sutra' is not enough to break the bottleneck of cultivation, and once I break through, my state may be unstable, I am worried that the process of breakthrough will affect you, so I ......"

Song Wei was a little depressed, and said, "It's because my cultivation is too low, not only can't I help you, but I may also cause chaos......"

Xia Ruofei smiled and said, "Fool! Do you know how difficult it is to go from the 8th layer of Qi Refining to the 9th layer of Qi Refining? My cultivation has already reached the peak of the 8th layer of Qi refining, but even that layer of window paper, no matter how much you cultivate, you can't break it." I didn't expect that after only a few hours of cultivation with you today, that bottleneck has actually begun to loosen! You can't help me! You have simply helped me a lot!"

Song Wei turned her worries into joy, opened her eyes wide and said, "Really?"

Her lips curled up slightly in a beautiful arc, and her heart was full of joy.

Xia Ruofei touched Song Wei's hair affectionately and said, "Of course it's true! Weiwei, you definitely have a prosperous life! Otherwise, as soon as I cultivate with you, I will immediately see the hope of a breakthrough?"

Song Weiqiao's face flushed slightly, and said, "Full of nonsense......"

Xia Ruofei laughed, and then said, "Weiwei, I'm going to use the Time Formation Method to retreat and cultivate, and strive to break through to the 9th layer of Qi refining in one go!"

Bing Xue's smart Song Wei immediately said: "You can cultivate with peace of mind, I'll go outside and guard it for you...... Dharma Protector!"

Xia Ruofei gently hugged Song Wei and said, "Thank you for your hard work! I estimate that the breakthrough process should not take too long, and we can continue to cultivate for a while! If I break through to the 9th layer of Qi refining, our efficiency will definitely be much higher when we cultivate, and you are already close to the 4th layer of Qi refining, so we can also make a breakthrough in this cultivation!"

Song Wei nodded heavily and said, "Well, then you should hurry up and cultivate! I'll go out first......

Xia Ruofei and Song Wei stepped out of the time formation together.

Although the two of them had been cultivating in the formation for several hours, only two or three minutes had passed in the outside world.

Song Wei casually took a book from the bookshelf next to her, smiled at Xia Ruofei and said, "I'll just read the book at the door for a while, you can cultivate with peace of mind! No one will come to disturb you!"

"Hmm!"

Xia Ruofei sent Song Wei to the door, then turned back to the house and locked the door again.

He waved back the Time Array Banner and stepped into the bedroom.

The breakthrough process would consume a lot of spiritual energy, and Xia Ruofei naturally wouldn't waste Yuan Crystal at such a time, so he planned to cultivate in the Spirit Map Space from the beginning.

Moreover, the effects of the Yuan Primal Realm and the Time Array Banner are superimposed, and they can reach two thousand times the time flow rate, so that even if the breakthrough process takes a little longer, Song Wei outside will not wait too long.

Xia Ruofei locked the door of the bedroom as well, and then summoned the Spirit Map Scroll from his palm, stuffed it into the quilt casually, and then entered the Spirit Map Space Yuan Primal Realm with a thought.

He came directly to the clearing in front of the Linglong Tower.

Liu Chengfeng is cultivating cross-legged, and the batch of living materials around him has consumed some of the outside time, and Liu Chengfeng has been cultivating here for a month.

Because of the soul seal, as soon as Xia Ruofei entered the space, Liu Chengfeng immediately felt something, and he directly interrupted his cultivation and opened his eyes.

Seeing Xia Ruofei standing not far from him, Liu Chengfeng hurriedly stood up, bowed to Xia Ruofei, and shouted respectfully: "Good master!"

Xia Ruofei waved his hand and said, "I also came in to cultivate, you don't have to worry about me, continue to cultivate!"

"Yes, master!" Liu Chengfeng replied.

There was a circle of open space around the Linglong Tower, Xia Ruofei walked to the other side, casually scattered the time array flag, and arranged the formation in an instant.

Then he stepped into the formation space, sat down cross-legged, stabilized his mind, and began to run the exercises of the first layer of the Great Dao Decision, and the entire Qi refining period stage was actually the exercises of the first layer of the Great Dao Decision.

The majestic true qi was surging in Xia Ruofei's meridians, quickly following the operation route map of the first layer of the Great Dao Break, and a trace of spiritual energy was inhaled into Xia Ruofei's body at a speed visible to the naked eye, and was transformed into true qi after passing through the dantian.

In fact, Xia Ruofei is basically saturated in the dantian now, but every Sunday, the true qi in the dantian will be condensed.

Xia Ruofei ran "The Great Road Decision" over and over again, without any distractions in his heart.

Once he entered the cultivation state, Xia Ruofei would not think about anything else, even if he was facing a breakthrough in cultivation immediately, his heart was still very calm, and his only thought was to control the true qi to continuously run in the meridians over and over again in accordance with the "Great Dao Decision" exercise.

The true qi in the dantian became more and more condensed, and Xia Ruofei even had a feeling of swelling, which was a feeling that would only arise after the true qi had been condensed to the extreme.

There is also a limit to the compression of true qi, which has something to do with the realm of cultivation.

In other words, in the realm of the 8th layer of Qi refining, the limit of his dantian capacity is almost that, and if he wants to continue to progress, he must break through to the 9th layer of Qi refining.

Once it breaks through, not only will the capacity of the dantian expand, but more importantly, the true qi will also undergo a qualitative jump, with the same amount of true qi, the 8th layer of Qi refining monks and the 9th layer of Qi refining monks are completely different, and the density of true qi will further increase.

Wisps of true qi were constantly compressed in the dantian, and the exercises of "Great Dao Decision" did not stop for a moment, and the true qi in the dantian also approached the limit density step by step.

The aura in the Lingtu space is quite abundant, and Xia Ruofei is in the formation range where there is still a seventy or eighty times time flow speed difference relative to the Yuan Primordial Realm, so the consumption of aura per unit time is even more than dozens of times.

In Liu Chengfeng's opinion, Xia Ruofei's cultivation place seemed to have appeared a whirlpool, and all the spiritual energy around him was swallowed up at an extremely fast speed, and even a "vacuum zone" of spiritual energy appeared for a short time.

Fortunately, the energy exchange efficiency between the Lingtu space and the external chaotic space is also very high, and it can still barely maintain such a rapid consumption, and it has not caused damage to the foundation of the space, but the concentration of spiritual energy in the territory of the early Yuan Dynasty inevitably began to slowly decrease, which is the energy formation of the Lingtu space, which is already a little unable to keep up with the speed at which Xia Ruofei consumes spiritual energy.

Liu Chengfeng couldn't help but be dumbfounded, and the admiration for Xia Ruofei in his heart was even more incomprehensible, especially under the effect of the soul seal, Xia Ruofei had become an omnipotent god in his mind.

Although the Yuan Chu Realm and the Mountain and Sea Realm are relatively independent, they are closely related at the same time, just like two interconnected containers, the concentration of aura on the side of the Yuan Chu Realm began to decline, and the energy exchange array could not keep up with Xia Ruofei's consumption rate, so the aura of the Mountain and Sea Realm naturally began to flow towards the Yuan Chu Realm.

The concentration of aura in the space is always in a dynamic equilibrium.

Xia Qing immediately noticed the change, and in a flash, he came to the Yuan Chu Realm.

At first, he thought that Liu Chengfeng had something wrong when he was cultivating, but as soon as he arrived at the Yuan Chu Realm, he saw Xia Ruofei cultivating in the Time Formation.

Xia Qing stood on the shore of the waterhole with a somewhat solemn face, paying close attention to Xia Ruofei's situation.

At the same time, Xia Qing also took a few pieces of Yuan Crystal from Xia Ruofei's warehouse where important materials were stored and prepared them first, once the concentration of spiritual energy dropped to a dangerous value, he would decisively arrange a spirit gathering formation around Xia Ruofei, and use the spiritual energy in the Yuan Crystal to maintain Xia Ruofei's cultivation.

Because of the huge scope of the Mountain and Sea Realm, the total amount of aura in the space is very large, although it has been "replenishing blood" towards the side with a low concentration of aura, but in general, the aura in the entire spirit map space has not decreased too much.

In the process of cultivation, Xia Ruofei couldn't feel the passage of time at all.

He didn't know how much time had passed, he was just immersed in the state of cultivation, and he didn't know that Liu Chengfeng had been stunned by his cultivation method of swallowing spiritual energy, and it also scared Xia Qing.

In fact, if it weren't for the fact that he had already had a sense of the breakthrough, Xia Ruofei would not have made an inch of progress in his cultivation no matter how he cultivated, the reason why the bottleneck was a bottleneck was that it was difficult to break through, and in the end, he might even cultivate for a long time, and his true qi would not change in the slightest, because the dantian was already saturated.

Only when we have felt the opportunity to make a breakthrough can we continue to compress our true qi through cultivation in one go like we are now, and then break through that bottleneck.

Xia Ruofei continued to cultivate in the formation for more than ten hours.

Finally, he felt that a layer of shackles had been broken at once, and there was a hearty feeling.

When that layer of shackles was broken, the flow speed of the true qi in Xia Ruofei's body suddenly increased by a few points, and then the dantian also began to slowly expand outward.

Xia Ruofei was slightly happy in his heart, but he quickly reined in his mind and continued to run the "Great Dao Decision" exercise.

The process of breakthrough lasted almost an hour.

In this process, Xia Ruofei's whole person seemed to be soaking in a hot spring, and he felt that every pore on his body was full of Shutai.

All the meridians involved in the first layer of "Great Dao Decision" have been broadened a lot in the process of this breakthrough, and they have also become more tenacious.

The broadening and strengthening of the meridians means that you can withstand more and stronger true qi.

After the dantian expanded, it seemed to be much emptier all of a sudden.

And the true qi in the original dantian was also extremely compressed in the process of breakthrough, and finally there was a qualitative change.

The true qi of the 9th layer of qi refining was obviously much more condensed than when he was refining the 8th layer of qi, Xia Ruofei roughly sensed it, and the same amount of true qi was at least twice as powerful as before.

In addition to the dantian and meridians being strengthened a lot, Xia Ruofei felt that after breaking through to the 9th layer of qi refining, it seemed that his body had also been tempered and became a lot stronger.

Especially in the process of breaking through, while the true qi was transforming the meridians, it seemed that a part of it had also penetrated into the muscles and internal organs, which made Xia Ruofei's whole body strengthen to a certain extent.

He knew that this would inevitably appear when the Qi refining period was about to reach the peak of the extreme, and the next time it would be to break through the Great Realm, and the strengthening of the body would be more obvious at that time.

Because of the expansion of the dantian and the condensation of true qi, Xia Ruofei obviously felt a lot of emptiness in the dantian, and he had an obvious "hunger feeling".

Xia Ruofei was ready to continue cultivating, on the one hand, he wanted to fill the empty dantian, and on the other hand, he wanted to consolidate his cultivation.

But at this moment, he suddenly frowned.

Xia Ruofei felt that it seemed that the concentration of the aura around him had dropped slightly.

He glanced up and saw Xia Qing standing on the shore with a hint of worry on his face, paying attention to the situation on his side.

Xia Ruofei groaned slightly, then temporarily gave up his cultivation plan, stood up and walked out of the range of the time formation, and appeared by the waterhole in a flash.

Seeing that Xia Ruofei had stopped cultivating, Xia Qing hurriedly bowed down and shouted, "Master!"

Xia Ruofei nodded slightly, and then asked, "How can I feel that the concentration of spiritual energy in the space has dropped somewhat?"

Xia Qing showed a wry smile and said, "Master, the speed at which you absorb the aura in the process of cultivation is too fast, and the energy exchange between the Spirit Diagram Realm and the Chaos Space cannot catch up with the speed at which you absorb, and the concentration of the aura will naturally drop. Fortunately, your cultivation time is not very long, and the total amount of spiritual energy in the Spirit Map Realm is relatively large, so it will not hurt the foundation of the Spirit Map Realm. ”

Xia Ruofei raised his eyebrows in some surprise and asked, "I just absorbed so fast, it is said that the Spirit Diagram Realm supports a few Qi Refining Cultivators to cultivate together, there should be no problem!"

Xia Qing was stunned for a moment, and angrily pouted at Xia Ruofei's Time Array Banner, which had not yet withdrawn.

Xia Ruofei suddenly realized. He knew that this would inevitably appear when the Qi refining period was about to reach the peak of the extreme, and the next time it would be to break through the Great Realm, and the strengthening of the body would be more obvious at that time.

Because of the expansion of the dantian and the condensation of true qi, Xia Ruofei obviously felt a lot of emptiness in the dantian, and he had an obvious "hunger feeling".

Xia Ruofei was ready to continue cultivating, on the one hand, he wanted to fill the empty dantian, and on the other hand, he wanted to consolidate his cultivation.

Xia Ruofei nodded slightly, and then asked, "How can I feel that the concentration of spiritual energy in the space has dropped somewhat?"

Xia Qing showed a wry smile and said, "Master, the speed at which you absorb spiritual energy in the process of cultivation is too fast, and the energy exchange between the Spirit Atlas Realm and the Chaotic Space can't catch up with you
