After killing the spider beast, Li Yao went to its lair. This spider does not build a web, but lives in a dark cave, Li Yao followed the cave all the way inward, and soon, he found the spider's nest.

It was a simple nest built by a pile of bones, and it was filled with all kinds of debris.

"Spirit stones, magic weapons?" Li Yao spread out the pile of debris, and found a pile of spirit stones and magic weapons in it.

Obviously, a monk planted it in the hands of this spider before, and its relics were collected by this spider...... Call!

Li Yao released a dust removal technique to clean up the dirt on the surface of these debris, and then he carefully examined it.

All the spirit stones are put away, and if the magic weapon is not damaged, it is also put away. In the blink of an eye, the total value of the treasures that Li Yao harvested here was tens of thousands of spirit stones, which made him feel a little refreshed, this spirit domain is really full of chances, even a spider and monster can have such a harvest here!

Of course, the premise of being able to get a big harvest in the spirit realm is that the strength is strong enough, otherwise, at this time, Li Yao will not be collecting treasures here, but his treasures will become part of these collections.

"What is this?" Suddenly, Li Yao's hand moved slightly. He pulled out a dark, cold token from a pile of debris.

This token is like gold but not gold, like jade and not jade, a token the size of a palm, but it weighs a thousand catties, if it weren't for Li Yao's amazing strength, I'm afraid it wouldn't be easy to pick it up at this time.

The most important thing is that when Li Yao Shennian searched for this pile of miscellaneous items just now, he did not find this token, if he hadn't picked these miscellaneous items with his own hands now, he would not have discovered the existence of the other party at this time.

"Can't sweep away the mind at all?" Li Yao's divine thoughts swept the token with all his might, but it seemed to sweep through a piece of nothingness, and he didn't feel it at all.

Li Yao instantly determined that the material of this token was not simple! He carefully looked at this token and found that on one side of it was mountains, rivers, grass and trees, sun, moon and stars, and on the other side was carved a simple text, which Li Yao did not recognize.

"I don't know what this token is, but the materials used to make this token are not simple, and if such materials are enough, they can completely build a weapon for me!" Li Yao did not hesitate at all, and directly put the token away.

。。。 After accidentally obtaining a bunch of treasures, Li Yao explored the lair inside and out, and he found nothing other than feeling that the aura here was extremely strong.

However, the strong aura is the biggest feature in itself, and the location here is hidden and the space is large enough, so Li Yao is very satisfied with the location of this lair.

"Let's build a foundation here!" Li Yao had a decision in his heart, he deliberately went to kill the spider demonic beast, originally he felt that the vicinity of this valley was very suitable for breaking through, and now it was normal for Li Yao to choose the lair of this spider demonic beast.

... Li Yao's cultivation can be said to have reached a bottleneck a long time ago, and since he has decided to build a foundation here, he will not hesitate.

He first auctioned him at the Shending Valley auction

The "Yin and Yang Array" was placed nearby, so as to ensure that his breakthrough would not be disturbed. This Yin and Yang Ritual Array can deal with several foundation building period monks when someone controls it, and even if no one controls it, it can generally delay for a while, leaving Li Yao enough time to react, and if an accident happens, it will not catch him off guard.

And in the outermost part

After the "Yin and Yang Two Ritual Arrays" were laid down, Li Yao added another layer near here

"Small Gathering Spirit Array"! This is derived from

"Floating Yuan" formation knowledge in the magic circle, this

The "Small Spirit Gathering Array" is very simple to arrange, but it requires a large amount of spirit stones to gather spiritual energy.

To be honest, the aura concentration in the nest of the spider demon beast was already strong enough, but when building the foundation, the higher the aura concentration, the better, and Li Yao would not be stingy with spirit stones at this time.

whereas

After the "Small Gathering Spirit Array" was also laid out, the next thing was the main event. According to the "Five Elements of Derivation", I want to carry it out

"The five elements build the foundation", it must be used

"Golden Crystal",

"Wood Heart",

"Water Pulp",

"Fire Glass Liquid",

The five spiritual objects of "Earth Lingzhi" are the core, and a set of guiding formations is arranged to extract the power of the five elements of the five spiritual objects when the foundation is built, helping Li Yao to condense the foundation of the five elements.

This set of guidance formations is quite complicated, but fortunately, Li Yaocong

"Fu Yuan" has gained some knowledge of the formation, otherwise if he wants to build a foundation at this time, he will definitely have to postpone a period of time to carefully study the layout of this formation.

...

"There is only this one of the five elements spiritual objects, I'd rather spend more time, but I have to be careful and careful!" Li Yao sat cross-legged on a futon, and in front of him were five kinds of spiritual objects such as golden crystals.

After carefully recalling the steps of arranging the method of guiding the magic circle, Li Yao finally started.

I saw him pinching the trick with one hand, and suddenly, a spiritual light hit into the golden crystal, and in an instant, the golden crystal flew out of the jade box, floating out of thin air, and then, the other four spiritual objects also levitated.

Call! Call! Call! Li Yao continued to play one magic trick after another, and the five spirit objects soon began to revolve around Li Yao, and gradually, their own forms began to blur.

A layer of aperture appeared around Li Yao's body, and the aperture had five colors, namely gold, cyan, blue, red, and black.

These five colors are distinct, but they gradually begin to penetrate each other...... In the blink of an eye, three days passed.

At this time, the aperture around Li Yao had turned into a spherical light mask, wrapping Li Yao in it.

Visible to the naked eye, hundreds of air currents containing five colors are like swimming fish, scurrying back and forth in the multicolored light mask.

And at this time, if you look closely, you will find that these five-colored air currents are still slowly devouring spiritual power, growing little by little!

However, Li Yao didn't care about these at this time, he closed his eyes and crossed his knees, meditating quietly to recover his mana.

I don't know how long it took, Li Yao suddenly opened his eyes. At this time, his mana had fully recovered, and his state had reached its peak.

"It's time to break through!" Li Yao didn't hesitate at all, he directly took out a Tsukidan and swallowed it on the spot.

The Zhuji Dan on Li Yao's body is not only the one he traded from Duan Ming at the beginning, he actually has a lot of it, as for its source...... Naturally, it came from the sinkhole of the Imperial Palace of the Yue Kingdom, and was left by the monk of the Yudan period.

Among the three passages that appeared in the stone hall at the beginning, at the end of the passages that Li Yao and the others entered were many magic weapons and other treasures.

And in the other two passages, the end of one of the passages should be all kinds of pills. The Tsuki-dan is just one of them, and there are many pills that can increase the cultivation of monks in the foundation-building period.

These pills were all obtained by Fu Yuan at the beginning, and later Fu Yuan died, so naturally they were all cheap Li Yao......... Monks build foundations, depending on whether their qualifications are good or bad, whether their mana is high or not, and the number of foundation dan that needs to be built is also different.

Some people may be able to succeed with one Tsukidan, and some people may need several to have hope. Li Yao has absorbed the spiritual roots of several people, and his qualifications are already considered to be middle and upper, plus he is now practicing the thirteenth layer of qi, and his mana is almost close to the foundation building period, so it is very simple for him to build a foundation at this time.

After a Tsukidan was put into his stomach, Li Yao suddenly felt a huge amount of mana pouring into his body. Under the action of Zhuji Dan's strange power, the mana that was originally distributed throughout his body began to condense and compress rapidly, and it didn't take long for Li Yao to transform a wisp of mana into a liquid state.

For Qi cultivators, the mana is gaseous, and it is all over the body. However, for the monks in the foundation building period, the mana became liquid and stored in the lower dantian.

And the most difficult step to break through the foundation building period during the Qi training period is to convert the first wisp of gaseous mana into a liquid state, and now Li Yao has easily completed this step, which means that if he just wants to build an ordinary foundation, then his breakthrough will have no twists and turns, and he will be able to reach the foundation building period all the way safely and steadily.

But Li Yao was obviously not just satisfied with this, he instantly played a trick at this time.

Suddenly, countless five-colored air currents like swimming fish around him began to swim rapidly. At the same time, there was a huge amount of aura around that was pulled over.

Call! Call! Call! Li Yao didn't absorb any of the countless spiritual energy, and at the moment of arrival, he was swallowed and absorbed by those five-colored air currents.

And with the irrigation of a large amount of spiritual energy, these five-colored air currents have also become more and more powerful. I don't know how long it took, but the trick in Li Yao's hand changed again.

In an instant, these five-colored air currents began to move towards the top of Li Yao's head, and they quickly merged together.

In the blink of an eye, a five-color yin-yang diagram appeared above Li Yao. Call! Call! Call! A large amount of spiritual energy was absorbed one after another, and these spiritual qi were first baptized by the five-color yin and yang diagram above Li Yao's head, and then poured into Li Yao's body.

Li Yao used the qi training method in "Five Elements Transformation and Derivation" to continuously refine these spiritual qi and transform them into mana, and with the supplement of these mana, the mana in Li Yao's body began to liquefy again.

Moreover, as more and more spiritual energy was absorbed above, the faster Li Yao's mana liquefied.

... I don't know how long this process lasted, but suddenly, the five-color yin-yang diagram above Li Yao's head suddenly collapsed.

Rumble! A huge pillar of multicolored light blasted directly into his body from Li Yao's Heavenly Spirit Gai, and in an instant, the five-colored yin-yang diagram that had just disintegrated in the outside world actually appeared directly in Li Yao's dantian.

Call! Call! Call! The countless mana that Li Yao had just liquefied was like a young bird returning to its nest, and it quickly surged towards the five-colored yin-yang diagram.

Gradually, the aura on Li Yao's body changed. At this moment, an invisible force was refining his body, and Li Yao could clearly feel that his longevity had increased.

At this moment, he also officially stepped into the foundation building period.

"It worked!" A smile appeared on the corner of Li Yao's mouth. (
