Just after noon on this day, the sky in the Twin Towers City was clear, and the streets were still bustling, and the Yizhi Pavilion, which had moved to the most central area of the city, was crowded with people.

Suddenly, the wind and clouds surged, and in a blink of an eye the thick clouds had completely covered the sun, and the sky was very quickly overcast.

After Wu Gang sent away a monk in the foundation building period, he took out a pill of Bigu Dan from the storage bag and threw it in his mouth, stretched his waist, and was about to go back to the house to take a nap, he had advanced to the ninth floor in the past few years, and his body had gained a lot of weight, and his expression was becoming more and more like the second shopkeeper in the shop.

Seeing the dark clouds in the sky, he muttered unconsciously: "It's going to rain? You deserve to be in the rain Cheng Fan, let you take Xiao Si'er to set up the formation, if you have to be able to set up the stone slab by yourself, don't you want to earn two more spirit stones?"

Righteous thoughts, but the dark clouds in the sky suddenly dispersed in an instant, and he was about to send out the white clouds and dogs, the impermanence of the world of life realization, when he saw a smiling man walk out of the main room in the backyard, this person looked like he was twenty-seven or eighteen years old, wearing a purple robe, his eyes were bright, and he had a short beard half an inch long on his chin.

"I've seen Shopkeeper Shi. Wu Gang was about to bow down, but suddenly felt that the person was a little different from before, "Shopkeeper, you ......" and looked at it carefully, and suddenly lost his voice and said: "You...... Are you in the foundation building period?"

The person who came was Shi An, he was stunned at first when he heard this, and then smiled faintly, "Exactly," and asked a little strangely, "How do you know?"

"Your aura is suddenly much stronger, how can I feel that it is stronger than the original Lao Li's mid-stage foundation building?" "Lao Li is the former shopkeeper Li, since he got Shi An's ten medium-grade spirit stones, the guys have called him Lao Li. Now he's back, but he's no longer a shopkeeper, but just an ordinary array mage.

"Really?" Shi An didn't pick up, but was still immersed in the joy after the foundation was built.

In the first three years after the establishment of Yizhi Pavilion, since the water spirit stone was no longer a problem, except for regularly going to the front hall to ask about the progress of Wu Gang's business and taking a little time to "produce" the attribute spirit stone, the rest of the time was completely immersed in the spirit gathering array without sleep. After cultivating to the tenth layer, the new wood spirit root had matured, and he no longer absorbed a trace of water aura, plus he took two more golden pills obtained from Liu Chen, and his cultivation during the consummation period was extremely smooth, and it only took less than two years to reach the peak.

At this time, Shi An's sea of qi was already the size of an adult's fist, and the dark blue spiritual mist in the middle was getting thicker and thicker. In the past five years, he has also read some thread-bound books written by the foundation building monks, and the similarity of these experiences lies in the role of the foundation building during the foundation building period, most of the Qi refining consummation monks' qi sea is too small, resulting in insufficient endogenous pressure, unable to liquefy the spiritual mist by themselves, so most of them use the function of the Zhuji Dan to generate huge pressure, so as to repeatedly compress the spiritual mist until it is all liquefied. The difference is that some monks emphasize the need for peace of mind in the process of liquefaction, some emphasize the need to constantly increase their understanding of life like Wu Gang, and even some emphasize the need to constantly accept the stimulation of great joy and sorrow. Shi An naturally understood a little in his heart when he saw this, the problem of mood is that the benevolent see the benevolent and the wise see the wise, and compressing the spiritual mist into liquid is the core.

Mother said that he didn't need to build a foundation pill, he only needed a combination of yin and yang, but all the cultivation in the consummation stage was yang water, where did the yin water come from? The sea of qi was saturated, and he couldn't absorb a little bit of yin and water qi at all, so how could he combine yin and yang? He thought about this question for a long time, and finally realized it three days ago.

In fact, Yin Water and Yang Water both belong to the water aura, there is no essential difference, but in the operation of a prominent and strong, one is prominent and delicate, now if the potential energy of the Yang water in the sea of qi is weakened, it becomes a very weak but extremely permeable Yin water, isn't it?

This process is a great challenge to Shi An's divine sense, and now he has thirty-two divine senses, placing all his divine senses in the sea of qi one by one, decomposing and weakening the dark blue yang water spiritual mist bit by bit, and sure enough, the transformed spiritual mist has changed from dark blue to light blue, but the two have not fused, but are clearly separated.

In this way, it took seven days and seven nights of work to transform without sleep, and the dividing line between light blue and dark blue in the spiritual mist became more and more centered. When the number of yin and yang water aura is just the same, the dividing line is no longer straight, but begins to bend slowly, the upper part to the left and the lower part to the right, and actually forms a yin and yang fish. Then the yin and yang fish began to spin, at first it was very slow, but as the spiritual mist churned violently faster and faster, and finally the dividing line between the two disappeared, and the yin and yang water aura completely fused together, and it was no longer possible to distinguish each other. The newly formed blue mist began to condense and liquefy, and in less than a quarter of an hour, it completely turned into Dan liquid, and at this time, there was no trace of spiritual mist in the sea of qi.

This result made Shi Anxin suspicious, this was liquefied? Could this be regarded as the advanced foundation building period? If it weren't for the black and shiny dirt that appeared on his body again, he really couldn't believe that the advance was so simple, so when Wu Gang asked him if he was advancing to the foundation building stage, he was stunned for a moment.

Back in his bedroom, he lay lazily on the bed, and he began to appreciate his changes, and he did have a little villainous look.

First of all, I found that my divine consciousness had changed, to be precise, it had become stronger, and the number of divine consciousness was still thirty-two, but each one was more than twice as large as before, so that the divine consciousness that had not been divided for a long time would soon usher in the critical point of the next fission.

The space of the sea of qi has also expanded by about thirty percent, and there is no longer a spiritual mist in the middle, but there is a thin layer of thick blue liquid at the very bottom of the sea of qi, if you touch it with your divine sense, it will flow with the touch, but it flows very slowly, grab a drop and lift it, you will find that there are filaments, and after breaking, it will quickly bounce back, and the viscosity is like honey.

Looking at his water spirit root again, it is a little thicker than before, and the number of branches seems to be more, which may be the evolution of the spirit root after the foundation building period that the master once said. After a closer look, he found that another change in his spiritual root was that some green spiritual roots appeared near the blue water spirit root, and the thickness was similar to that of the water spirit root that had been opened at the beginning, so it didn't mean that this was the newborn wood spirit root. Shi An casually took out a small wood spirit stone, he was not aware of the wood spirit qi before, and this newborn wood spirit root was also receiving and releasing the wood spirit qi in and out.

There is basically no change in physical appearance, and Shi An, who is twenty-seven years old this year, does not plan to restore his body to the appearance of thirteen or fourteen years old, so he does not nourish his body with aura.

Now that it's the foundation building period, I should be able to see my mother again, and I can also expand the space of the Cave Stone. Thinking of this, Shi An couldn't help but be excited, even though his mother couldn't see him, he still dressed himself up.

Entering the Cave Stone, he didn't notice that there was anything different in the cave, except that there was an additional fluorescent passage on the left stone wall near the first mountain room.

Shi An remembered what his mother said, "When you enter the next mountain room, all things that are not the original of the current mountain room will no longer exist", Shi An first entered the first mountain room, and put all the items stored in it later, such as several piles of spirit stones, a pile of stone slabs, and the spirit gathering array of the Qi refining period into the storage bag, and then walked to the aisle, still according to the method last time, probed his divine sense to that layer of light, and with a light touch, the enchantment hole opened, and he dodged in.

This chamber is twice the size of the previous chamber and the roof of the cave is a bit higher than the previous one. The furnishings are simpler, there is no bed, just a stone table and a stone chair. There were only three jade slips on the table, and there were no magic artifacts or anything like that he particularly wanted. And in this corner of the mountain room, there are still traces of things buried.

Just as he was about to get closer to look at it, the light screen appeared on the wall of the mountain room again, and the beautiful woman appeared again.

"First of all, son, congratulations on your advanced foundation, and from then on you will no longer be a mortal, but a true monk. ”
