The so-called foundation building is actually a deeper level of scripture washing, and only when the foundation is built can the monk lay a solid foundation in order to go further on the road full of difficulties and dangers in cultivating the truth. However, the foundation building itself was a sad hurdle, and this hurdle tripped over more than ninety percent of the peak Qi Refining Stage cultivators.

"It's been more than ten years, and I've finally come this far!"

Tang Mianpan sat in the practice room, recalling the bits and pieces of being a slave in the mine, more than ten years had passed, and his still young body made it difficult for him to believe that he was a middle-aged man in his thirties.

The aging of Qi refining period cultivators is much slower than that of mortals, and their lifespan is relatively stronger, and they can basically live a long life of 100 years while ensuring their physical functions.

"If I fail, I'll be getting old by the time I'm fifty. ”

Tang Mian laughed to himself, he began to arrange the prohibition and magic circle for himself unhurriedly, he understood that every step from now on must not be sloppy.

At this time, his cultivation had just broken through to the twelfth layer of the Qi refining stage, and he still needed to consolidate his cultivation before taking the Tsukidan, and through condensing mana, his cultivation would gradually increase to the level of the peak of the twelfth layer.

The Chalcedony Pill had already been consumed, and Tang Mian had other intensive cultivation pills in his storage bag, but at this time, he didn't plan to take the pills to increase his cultivation.

"It's good to spend more time, I also need to increase my comprehension of the realm. ”

The One Hundred and Third Cave Mansion was closed again, Tang Mian also slowly closed his eyes, and the twelfth layer of the "Thunder Fire Technique" was running in his body, and the surrounding heaven and earth aura was pulled towards his acupuncture point to converge.

Half a year passed in the snap of his fingers, and the aura naturally emanating from Tang Mian's body had grown a little stronger, and at this time, he was already standing at the final stage of the Qi refining period, the peak of the twelfth layer.

"Sure enough, even if we have come this far, we are still far from building a foundation. ”

Tang Mian smiled bitterly and opened his eyes.

Legend has it that those geniuses who possess the best spiritual roots will basically not encounter bottlenecks at the beginning of their cultivation, and when they cultivate to the peak of the twelfth layer of the Qi Refining Period, they will be the first to appreciate some of the scenery of the Foundation Building Period, and some of them don't even need to take the Foundation Building Pill when they are building the Foundation, and Tang Mian obviously does not belong to such a genius.

The Blazing Fruit brought Tang Mian a fire-attribute spirit root, but it didn't bring him a higher spirit root qualification, but for Tang Mian, there was nothing to regret, he was lucky enough.

"It's time for you to show your value!"

Tang Mian's divine sense poked into the storage bag, and two jade vials sealed by rune paper appeared in front of him.

There are many types of Tsukidan, but the efficacy of the medicine is uneven. In the territory of the three counties, the Qingling Pill is the one with the best medicinal effect in Zhuji Dan, and it is the treasure medicine that all Qi refining period cultivators dream of.

It is rumored that refining the Qingling Pill requires more than a dozen elixirs, and there are extremely strict requirements for its year, and this alone greatly limits the number of Qingling Pills. In addition, even if the materials are sufficient, alchemists who have the ability to refine this pill are extremely rare, which leads to the fact that the Qingling Pill has always been a rare thing, and it is extremely difficult to seek this pill for its descendants even during the foundation building period.

Of the three Zhuji Dan in front of Tang Mian, two of them came from the disciple surnamed Cao of the Ice and Fire Sect who was killed in Cangmang Mountain more than ten years ago. In the battle of Huangshiling, Yan Lei, a fake Dan stage monk, recognized the silver and white flying sword at a glance, and threatened to avenge this person, which can be seen that this person has a high status in the Ice and Fire Sect.

There was also a Qingling Pill that was a reward from the City Lord's Mansion, which was basically an unexpected joy, because Tang Mian didn't expect that those Qi Refining Stage cultivators who he killed casually at that time would actually be recorded as merit points.

Holding three Qingling Pills in his hand, Tang Mian didn't dare to take it lightly at all, because if the first foundation building failed, the success rate of the second foundation building would decrease to varying degrees, and as for the third foundation building, the success rate was almost zero.

Tang Mian repeatedly scrutinized the red makeup and Chen Li's foundation building experience in the sea of knowledge, and then picked up the pill bottle in front of him and poured out a yellow and clear pill from it.

"Let's get started. ”

Tang Mian swallowed the Qingling Pill into his abdomen, and then closed his eyes. At the same time, the divine consciousness stored in the center of the eyebrows spread out to the hundreds of limbs, which allowed Tang Mian to perceive every change in his body extremely clearly.

When the Qingling Pill entered the abdomen, it turned into pure medicinal power and entered the depths of the body, and after coming into contact with the flesh and blood meridians, this extremely pure medicinal power immediately disappeared without a trace.

With the passage of time, the dantian suddenly became warm, and it seemed that the medicinal power that had disappeared in the flesh and blood just now had come to the dantian.

However, this comfortable feeling did not last long, and the temperature in the dantian rose extremely highly, and soon came to the point where it was unbearable for Tang Mian.

After cultivating the "Leaving the Fire Forging Body Technique", Tang Mian was already accustomed to the burning pain of the Leaving the Fire Forging Body, but at this time, the blazing heat of the dantian still made him unable to bear it, and the scorching of the high temperature made him feel that the dantian was about to be burned.

While the temperature of the dantian was rising, the rest of Tang Mian's body was surprisingly cold, and the blood in his limbs seemed to be frozen.

These two sensations, one cold and one hot, existed in the body at the same time, and lasted for a long time, Tang Mian gritted his teeth and forcibly kept his consciousness in a state of wakefulness.

I don't know when it started, the meridians around Tang Mian became unbearable, and there seemed to be tens of thousands of ants in the flesh and blood. At the same time, his skin was covered with a foul-smelling gray substance, which was an impurity produced by his body after washing the menstrual marrow.

The appearance of gray matter is only the beginning of foundation building, and the reshaping of the dantian is the most important level of foundation building. At this time, the temperature of Tang Mian's dantian had risen to the limit that his body could bear, and the mana stored in it was like boiling water surging wildly, even with Tang Mian's spiritual power, he could no longer bear the pain from the dantian at this time, and his eyes were black and he fainted directly.

Just after Tang Mian fainted, the flesh wall of his dantian finally couldn't withstand the high temperature and began to fall off like wallpaper. At the same time, the boiling mana in the dantian turned into a little mist and spread out to the surroundings, attaching to the severely damaged flesh wall of the dantian.

When Tang Mian woke up again, there was a tingling sensation in the sea of consciousness in the center of his eyebrows, but at this time, he didn't care about the exhaustion of his divine sense, and directly looked inward to check the situation of the dantian.

"Holy!"

Although Tang Mian had been mentally prepared, the tragic situation of the dantian still shocked him a little.

"It's not enough!"

Tang Mian forcibly squeezed out some divine consciousness from the sea of consciousness, shrouding the dantian in it, he found that the destruction of the dantian was not complete, and those manas had already begun to repair the work, if it was allowed to continue, I am afraid that it would be difficult to succeed in building the foundation this time!
