After Ye Changsheng broke through the ninth layer of Qi cultivation cultivation, this time, the green sparrow that was often churning in the gourd space finally began to shed its hair for the fifth time. The sparrow, which had lost its green feathers, was like a white chicken, which was extremely fun, and could not fly up when standing on the ground, so it ran over with two small feet.

Ye Changsheng sat down cross-legged and began to continue to swallow the pill to improve his cultivation.

He planned to raise his cultivation to the bottleneck of the ninth layer of Qi cultivation in one fell swoop, and then swallow the Zhuji Dan to see if he could build the foundation.

Once he has cultivated to break through the Qi cultivation period and successfully build a foundation, he should be able to use the third layer of the Little Five Elements Divine Light at will, and he can use the fourth layer of the Little Five Elements Divine Light, and even take the risk of swallowing multiple pills to use the fifth layer of the Little Five Elements Divine Light.

The fifth layer of the Little Five Elements Divine Light, the third layer of the Little Five Elements Divine Light that Ye Changsheng often uses now is already infinitely powerful, and it can withstand the blow of the thin sword of the Jindan period monk, and the fifth layer is really exciting.

It's just that everything is not so simple, and the spiritual power accumulated by the ninth layer of Qi cultivation far exceeds that of the eighth layer of Qi training. Half a year later, Ye Changsheng was disappointed to find that there were few entries.

With such a cultivation speed, I don't know how long it will take to reach the realm of the Great Perfection of the Qi Cultivation Period, and Ye Changsheng can't even estimate that time.

So Ye Changsheng finally realized that if he didn't try to refine the Spirit Pill, it would be too slow to improve his cultivation with the Returning Spirit Pill alone.

Anyway, he also had accumulated a lot of Naling Pill materials on hand, and Ye Changsheng decided to start trying to refine Naling Pill.

At this time, he had already comprehended all of Xiaoyue's alchemy experience, and the rate of refining the Guiling Pill had reached sixty percent, so there was still some hope for refining the Naling Pill.

The refining method is similar to the refining of the Guiling Pill, but the heat and details are different, and the purity of the spiritual liquid is also much higher.

Ye Changsheng was ruthless, counted the more than 100 copies of the withered blood vine and the other three spirit grasses that he still had, and immediately put his mind at ease.

The refining of the first furnace of Na Ling Pill took four hours, but it still failed as always, Ye Changsheng was not discouraged and began to refine the pill frantically.

At this time, there were only four pieces of rust left on the alchemy furnace, and the alchemy felt much smoother than at the beginning, I don't know if it was Ye Changsheng's own hallucination or the fact.

After a month, there were only seventy-three copies of the withered blood vine in Ye Changsheng's hand, but the Na Ling Pill had not been cultivated.

The main reason is that the purification and condensation of the withered blood vine is too difficult, and although Ye Changsheng's spiritual power is grand, it is still a little insufficient.

After persisting like this for another month, when there were only thirty parts of the withered blood vine left, the first furnace of the Naling Pill was finally refined.

The number of Cheng Dan of Naling Pill is much less than that of Qi Replenishing Pill and Guiling Pill, and there are a total of 19 Dan in the first furnace.

Ye Changsheng looked at the small bottle of Naling Pill in front of him, and suddenly had an impulse like a cow, it was not easy, this alchemy was too expensive.

After the remaining thirty withered blood vines were consumed, another month had passed, and Ye Changsheng had a total of seven furnaces of Cheng Dan, one hundred and fifty pills, and the Cheng Dan rate was more than two percent.

When taking the Naling Pill to enhance cultivation, it is not to take only one type separately like the Guiling Pill and the Qi Replenishing Pill, but to take it together with the Guiling Pill or the Qi Replenishing Pill. There is a character in the name of the Naling Pill, which in addition to the spiritual power it can provide, it will also improve the efficiency of the monk in absorbing all kinds of spiritual power.

In the following period of time, Ye Changsheng swallowed one Na Ling Pill and several Gui Ling Pills every day, and his cultivation began to grow rapidly.

There are no years in cultivation, and most of the time is fleeting. Ye Changsheng, who had improved his cultivation with the Naling Pill, finally touched the bottleneck of the ninth layer of the Qi cultivation period at this time, and the growth of spiritual power began to stagnate. In other words, Ye Changsheng had reached the realm of the Great Perfection of the Qi Cultivation Period.

Next, it is time to hit the foundation building period.

In order to prepare, Ye Changsheng relaxed and wandered around the city for a few days, every time he walked around and smiled. After practicing in retreat for so long, when I went out again, I felt like I was in a different breath, and it seemed that the sky was a little bluer.

There seemed to be more monks from the Fire Cloud Sect in the city than before, and all of them had grim expressions, not knowing what major events had happened. It's just that these have nothing to do with a small casual cultivation like Ye Changsheng.

When the state is adjusted to the best, Ye Changsheng sits cross-legged and meditate, preparing enough Naling Pill and Guiling Pill, and the Qingxin Baoyu is also full of spiritual power, and then begins to impact the foundation building period.

The foundation building period, as the name suggests, means laying the foundation. The first step in building a foundation is to operate the spiritual power in the body, introduce the spiritual power scattered in the various meridians into the dantian, and then compress it to the extreme, and finally form a stable liquid state, and the foundation building period has been completed since then.

What Ye Changsheng is doing now is to first use his own strength to attract the spirit into the dantian, and when the spiritual power is insufficient, he will use the spirit pill to replenish the spiritual energy, and wait until the final spiritual power cannot be compressed before trying to take the Zhuji Dan.

In addition to being able to provide a large amount of milder spiritual power, Tsukidan can also speed up the liquefaction of gaseous spiritual power, so for monks, if they want to build a foundation, if they have Tsukidan, the success rate will increase a lot.

Large groups of gaseous spiritual power poured from many major meridians and branch meridians up and down Ye Changsheng's body to the dantian, and the concentration of spiritual power in the dantian was also constantly increasing, but it was still far from the liquid state.

After a few breaths, all the spiritual power that could be mobilized in Ye Changsheng's body had been sent to the dantian, and the empty meridians began to frantically absorb spiritual energy from the outside world.

At the same time, Ye Changsheng swallowed a Naling Pill, and then after a breath, he swallowed several more Guiling Pills, and so on.

After a few days, the spiritual power in Ye Changsheng's dantian was already extremely thick, and it was almost dripping water, but it still maintained a gaseous state. Fortunately, Ye Changsheng had prepared a lot of Na Ling Dan and Gui Ling Pill, and the aura in this Far East City was strong, and the meridians were still transmitting spiritual power to the dantian.

After another while, there was still no sign of liquefaction in the gaseous spiritual power, but it was a few points thicker. However, at this time, it had become extremely difficult for the meridians to transmit spiritual power to the dantian, and the extremely thick spiritual power that had already existed in the dantian had even begun to disperse outward.

After another two days, the inflow and outflow of spiritual power in the dantian has reached a balance, such as how to swallow the pill, the total amount of spiritual power dissipated and transported is still similar, but the spiritual power has still not been liquefied.

Ye Changsheng knew that if he didn't build the foundation pill, this impact on the foundation building would be a failure. Next, if the strong gaseous spiritual power in the dantian is not properly dissipated, the spiritual power will surge, go crazy, and even die.

Ye Changsheng picked up the vial, uncorked it, and swallowed a Zhuji Dan.

After the Zhuji Dan was in the stomach, it exploded in an instant, becoming a large mass of liquid, and then dispersed to the meridians of the whole body, and then countless spiritual power suddenly came out of the meridians, and continued to surge into the dantian.

The spiritual power in the dantian entered the balance and was instantly broken, and a large amount of spiritual power poured into the dantian. The large mass of gaseous spiritual power that had been silent for a long time began to slowly circle, and then as the spiritual power continued to pour in, the air mass swirled faster and faster, and it became smaller and smaller.

Ye Changsheng was overjoyed in his heart, and said secretly: "There is a door!"

In a short time, the air mass had shrunk from the size of the bowl to the size of a fist, and as the speed of rotation increased, a fiery red droplet finally formed at the center of the vortex where the pressure was at its highest.

As soon as the droplet was generated, it began to desperately absorb the surrounding spiritual power, and I saw that the fist-sized spiritual power vortex was actually absorbed by the red droplet, and finally formed a red droplet the size of a thumb.

The effect of Zhuji Dan in the meridians has still not dissipated, and a large amount of spiritual power keeps pouring into the dantian from the meridians, and the red droplets are getting bigger and bigger, and in the end, when it is about the size of a fist, it finally no longer absorbs spiritual power, but is quietly suspended in the dantian.

If it was an ordinary monk, at this time, the foundation building would be considered completed, but Ye Changsheng was cultivating the "Five Elements Creation Sutra", but this big red droplet was clearly a fire-based spiritual power, what was this? If he continued to cultivate based on this, it would inevitably lead to an imbalance in spiritual power, and he would explode and die.
