Dao aura was pouring out from the stalagmites, and the thick aura even briefly formed bursts of spiritual mist before slowly dissipating into the air.

After staying here for a day, Xu Wen has discovered the law of this spiritual acupoint, which erupts every day in the eight hours of Zi, Chou, Yin, Mao, Wei, Shen, You, and Xu, and the concentration of spiritual energy is very strong.

If you only talk about the concentration of spiritual energy, it is not even below the ordinary spiritual spring.

However, the spiritual spring has the opportunity to produce some special spiritual objects, which the spiritual acupuncture cannot compare to in any way.

Xu Wen's cultivation had already reached the peak of the third layer, and after staying here for a day, even if he didn't cultivate, he was tempered by the abundant spiritual energy, and he was like a spring, as if he could break through on his own at any time.

Everything was over, Xu Wen couldn't hold back any longer, jumped on top of the stalagmite, and sat down cross-legged.

Without urging, the Qinghuang Gong automatically flowed, and the aura that had been accumulated in the cave for a long time suddenly swarmed in, rushing straight into Xu Wen's body.

The process of cultivation is a process of constantly climbing to the peak, and every time you ascend to the realm, there will be many obstacles.

There are from the first layer of gas refining to the second layer of gas refining, from the early stage of gas refining to the middle stage of gas refining, and from the beginning of gas refining to the foundation building, the more complex and low the strength of the spiritual root, the greater this obstacle will be.

The difference in qualifications is a huge gap, and the difference will be very big in the process of cultivation, and it is even more different when facing the levels, without ten times, a hundred or even a thousand times the external force, it is impossible to cross it at all.

The worst Five Spirit Roots, cultivators for a lifetime will not be able to cross the second layer of Qi refining.

If it was the original spiritual root qualification, Xu Wen's cultivation limit in this life was the early stage of qi refining, and there was no hope of breaking through the middle stage of qi refining.

However, with the help of the Heaven Replenishing Root, his spiritual root strength is enough to 24 points, and the five elements are balanced, which is already comparable to the ordinary Four Spirit Roots.

The Four Spirit Roots already had a slight chance to touch the foundation building, and the bottleneck in the middle stage of Qi refining would not be very strong.

Three days later, the aura erupted again, and after three days of penance, Xu Wen's spirit and spirit reached the optimal state.

Faced with this moment of intersection of the old and the new, the transformation of yin and yang, he did not hesitate, and the surging mana rotated rapidly, incorporating the rich aura into his body, which actually made his body feel a certain feeling of fullness.

Too much aura didn't have time to refine, and he ran around in the meridians, impacting many cracks, and tiny blood streaks began to appear all over his body.

Xu Wen was unmoved, and continued to frantically incorporate the aura into his body.

There were more and more bloodshots, but the blue light between his eyebrows was getting stronger and stronger, and at a certain moment, he suddenly sighed:

"Open it for me!"

The invisible shackles burst open, and a bit of blue light rushed out from between his eyebrows, rotating around his body, removing all injuries one by one.

At the same time, the black bead rice accumulated in the body finally had a place to vent and was completely integrated into the body, and the spirit that had already reached the limit suddenly rose a lot.

With a crackling sound, his body rose two inches higher, and he was in his early eights.

With tough and shiny skin and muscles full of strength, he finally got rid of his emaciation and was full of indescribable health and beauty.

The bright eyes under the thick eyebrows flashed with a majesty that was completely absent before.

After absorbing the vitality of the black bead rice, his divine soul was much stronger, and his coercion was no less than that of a monk at the fifth level of qi refining.

With a long roar, Xu Wen flew up, feeling the surging mana in his body, and his heart was extremely happy.

The middle stage of Qi refining is a watershed for low-level casual cultivation, and it is difficult for most helpless casual cultivators to break through this level.

In the ghost market, most of the monks are in the early stage of qi refining, and a few are considered masters in the middle stage of qi refining.

And today, he is finally among them, and the time will be less than a year.

Compared with the third layer of qi refining, his mana has increased by more than thirty percent, and he can finally support a battle of a certain intensity, instead of running out of mana after a few spells like in the early stage of qi refining, and he can only fight hand-to-hand.

It was precisely for this reason that ordinary Qi Refining Early Stage cultivators rarely went out on adventures, and their mana could not cope with the endless dangers of the outside world at all.

And the cultivators in the middle stage of Qi refining can already try to get out of the familiar place and explore the unknown land.

Promoted to the fourth layer of qi refining, the Qinghuang Gong has dozens of more spells, both wood and fire, and some earth attribute spells.

Wood gives birth to fire, fire gives birth to earth, and the mana of the monk in the middle stage of qi refining has been able to transform twice and cast earth-attribute spells.

After carefully figuring out one of the spells for a while, Xu Wen suddenly pinched the spell with both hands, and the Dao mana continued to transform in his hands, first from wood to fire, and then from cremation to earth.

Finally, with a wave of his hand, a yellow light fell on the rock he had just filled the passageway.

The rocks fall in a slump, from petrified powder, and finally turn into dirt, firmly bonding the surrounding rocks together.

The spell of fossil to mud came at a very timely time, not only to completely solidify and block those passages, but also to clean up the cave and expand the passages.

For the next few days, he stayed underground, casting spells such as turning fossils into mud to completely level the cave into a convenient place for walking and cultivating.

It also leveled and expanded the entire underground passage, so that he could easily travel back and forth.

After a few days, the spell of fossil to mud has become very familiar, and the speed at which it can be cast is no less than that of ordinary wood-attribute spells.

Looking at the suddenly new cave, Xu Wen's heart suddenly rose with countless longings, with this spiritual cave, his cultivation would no longer have any obstacles in a short period of time.

And the source of all this is undoubtedly the Heavenly Eye Treasure Light Technique.

Without this magical power, even if the opportunity is right in front of him, he probably won't be able to find it, let alone seize it.

Thinking of this, Xu Wen's heart suddenly moved.

In the past, every time he was promoted to a realm, there would be some changes in the Heavenly Eye Treasure Light Technique, but this time he advanced from the early stage to the middle stage, and there was no reason why he would not be promoted.

However, it used to be once a day, but now it is twice a day?

Although the effect is huge, this magic power is not an offensive spell, and there are not many times when it is used every day, once a day is enough, and any more is just a waste.

With the thought of it, the Heavenly Eye Treasure Light Technique suddenly spread, and the colors of the surrounding things instantly became blurred, only a bright gray light appeared on the stalagmite where the spirit cave was located.

Soon, Xu Wen noticed something different.

Before, the effective range of the Heavenly Eye Treasure Light Technique was only half a zhang, but now, the stalagmite was obviously half a zhang away from him.

He immediately took a few steps back, and the treasure light on the stalagmite was still there, and it was not until he retreated a foot away that the treasure light disappeared.

After a few times, Xu Wen finally determined that this time the Tianyan Treasure Light Technique was promoted by distance, not between intervals.

Distance is actually just as important as intervals, cultivators have a strong sense of vigilance, and no one likes to be too close to them.

The previous Heavenly Eye Treasure Light Technique was very troublesome to use, and it had to be within a distance of half a zhang to take effect.

This distance is already very close, and if you can touch each other by raising your hands at the same time, if it weren't for the ghost market, which is similar to a stall, it would have caused a dispute long ago.

Now, there is no such hidden danger at a distance of one zhang, and the efficiency of observing things will be greatly improved......
