Qin Lang's plane was from the capital to Liaoshen Provincial Capital, and at noon, Qin Lang arrived at the Provincial International Airport.

Without making any stops, Qin Lang directly found a car rental company at the airport, rented a Guangben off-road car at a price of 1,500 yuan a day, and drove straight to Shaohu Mountain.

The place of earth and fire is located in the Shaohu Mountain.

Qin Lang was already quite familiar with the route, after all, he had been here several times before.

Parked the car at a farmhouse under Shaohu Mountain, the boss there still knew Qin Lang, saw Qin Lang, smiled and asked Qin Lang if he was going to Shaohu Mountain to walk through the mountains again, Qin Lang smiled, even if he acquiesced.

Qin Lang put on his backpack and sped up all the way, and he arrived at the destination that others would take three hours to reach, but he arrived in forty minutes.

The place of earth and fire is still the same as when he left, the Tang Sect, which used to dominate the place of land and fire, has long been lost in Liaoshen Province because most of the elite, and now it can only shrink in the Sichuan and Shu area.

No one bothered, which was exactly what Qin Lang wanted.

Qin Lang took out the necessary materials for refining the Wisdom Pill such as the Zhuji Grass, and took out the Purple Cloud Pill Furnace again, and with a thought in his mind, the Purple Cloud Pill Furnace was spinning in the air, and those alchemy materials also flew into the Dan Furnace.

The Determination Pill is a low-grade pill, and with Qin Lang's current alchemy strength, it can still be refined.

It's just that for the sake of insurance, Qin Lang still divided all the materials into two, so as not to fail in alchemy once, and all the materials would be consumed.

Half an hour later, the first alchemy was over, the result was not very good, although the pill was formed, there was a difference in the key step, and the grade of the Dingzhi Pill refined by the guide zhì could not reach the level of the lower grade pill, and the medicinal effect was also greatly reduced.

Fortunately, there is one more chance.

After a short rest, Qin Lang remembered the mistakes made in the previous alchemy process and started again.

This time, Qin Lang controlled the mistake within an acceptable range, and half an hour later, a green pill with bursts of fragrance was successfully refined.

The Dingzhi Dan was only about one-fifth the size of a pigeon's egg, so Qin Lang carefully put it into the porcelain vase along with the one he had refined before, and then got up to leave.

The non-stop trek for a moment can be described as very tiring for ordinary people, but for Qin Lang, his super physique makes him not feel tired now.

Return, pick up the car, return to the airport, get on the plane, have dinner on the plane, and at half past seven in the evening, Qin Lang returned to the capital.

It almost only took ten hours to go back and forth between the capital and Liaoshen Provincial City, and Qin Lang really didn't waste any time along the way.

When he got home, Qin Lang didn't rest immediately, but took out the top-grade spirit stone that had been consumed about the same, as well as the heart of agarwood, and continued to meditate and practice qi.

Half an hour later, Qin Lang felt that the true yuan in his body had frozen for a moment, as if he had been cast the time stop law, but immediately after, those true yuan surged wildly, almost uncontrollable, and the entire room was shrouded in the fluctuations of the true yuan.

Click, click.

The strong air flow driven by Zhenyuan blew the lighter items in the living room to the ground, and several sofas also made a clicking sound, which was blown by the strong wind, and the wood inside the sofa sounded.

Qin Lang was excited.

Breakthrough, finally about to break through!

Originally, it was estimated that he should be able to break through to the foundation building period in these two days, but now that the breakthrough has happened, I am still very excited.

However, Qin Lang was not carried away by the joy, the most important thing now was naturally to control his mind and concentrate on completing the breakthrough process.

Qin Lang didn't have any worries.

Anyway, the Determination Pill is in his pocket, and if there is an accident during the breakthrough process, the Determination Pill will help him resolve the danger.

The breakthrough of the Qi cultivation period to the foundation building period marks the road of cultivation, and it has reached a new level, and the world faced by the foundation building monks is undoubtedly invisible to the Qi cultivation monks.

And the breakthrough process is naturally huge.

The things hanging on the wall were all brought down by the strong wind caused by the fluctuations of the true yuan, and the living room was in a mess, Qin Lang sat in the middle, letting the true yuan surge, and always controlled the calmness of his mind.

The true element in the body is frantically impacting the acupuncture points of the whole body, and all the meridians in the body are bearing the baptism of the true element.

Qin Lang clearly felt this qiē, and his expression was very calm.

Because, opening up the meridians and cutting the hair and marrow is the most important change that will occur when the qi training period enters the foundation building period.

The original intention of building a foundation is to lay a solid foundation, specifically to lay a solid foundation for cultivating truth.

Don't look at the Qi cultivators, there will be some small spells, it seems that the Qi cultivators have also embarked on the path of cultivation, but in fact, the real cultivation will not be counted until the foundation building period.

The foundation building period is over, and the real door to cultivation can be regarded as open.

When you first enter the foundation building period, there will be a process of true yuan opening up the meridians of the whole body to help cut hair and wash the marrow, and after the meridians are opened, the speed of absorbing the aura of heaven and earth will be doubled, and the meridians will be opened, and the true yuan can also be stored in it more, which is also the main reason why the ability of the foundation building monk to use the true yuan will far exceed that of the qi cultivator.

Qin Lang felt that his meridians were undergoing a baptism.

This is thorough, and it is completely different from the previous configuration of Chinese medicine for medicinal baths.

However, because the true element is very unstable both inside and outside the body, Qin Lang needs to rely on his divine sense to stay awake and control these true elements, and the loss of divine consciousness is really very large.

About ten minutes later, Qin Lang felt that his head was experiencing dizziness.

This is a sign that the consciousness has reached a dangerous stage.

For other monks, this is actually nothing, they can grit their teeth and carry it, but Qin Lang has the hidden danger of foreign Yuan Shen in his divine consciousness, once his divine sense is weak to a certain extent, the foreign Yuan Shen will definitely launch a counterattack regardless of a qiē!

Sure enough.

Qin Lang only lasted for half a minute, and then he felt a boom in the sea of consciousness, and the small group of foreign primordial gods belonging to Xuan Qingzi frantically impacted in his sea of consciousness.

Pain!

This was Qin Lang's only feeling.

It was as if someone had forcibly shoved his hand into his head, and then the hand was still stirring in his head desperately.

That kind of pain, if he could, Qin Lang didn't want to endure it a second time.

However, Qin Lang still remained sober.

The mutation really happened, Qin Lang took out the small porcelain bottle from his pocket in a hurry, uncorked the bottle, and swallowed the two Determination Pills into his mouth.

Suddenly, a refreshing sweet taste, accompanied by the rapid dissolution of the Determination Pill, dissolved in his tongue and throat, and at the same time, his weak consciousness seemed to be suddenly added with a solid layer of armor, and it suddenly stabilized from the wind and rain.

This feeling is like a person staying in an eight-level gale and being blown around by the strong wind, but suddenly a closed house falls from the sky, and the person stays in the house, although there is still an eighth-level gale outside, but the person does not have to be blown by the wind again.

"Dingzhi Dan, it really lives up to its name. ”

Qin Lang smiled and said to himself.

Now his divine sense is extremely stable, and the small group of foreign primordial gods in the sea of consciousness was expelled to a corner at once, and obediently fell silent.

Qin Lang was glad that he helped Lin Xinru treat Lori disease yesterday, in exchange for a foundation building grass, which led to the Determination Pill.

If Dingzhi Dan was not there, Qin Lang did not dare to guarantee that there would be no accidents when he broke through the foundation building period this time.

The next breakthrough process became much more stable.

While opening up the meridians, Zhenyuan is also refining the meridians, making the width and toughness of the meridians significantly improved, different from the heart-rending pain when the meridians are forcibly opened, Qin Lang feels warm all over his body, and every pore is comfortable.

After another half an hour had passed, all the True Yuan had returned to their places, the living room had returned to peace, and when Qin Lang opened his eyes, the depth in his eyes had increased even more.

And Qin Lang felt that his control and mobilization of true qi was much stronger than when he was in the qi training period!

"Test the speed at which True Qi runs in the meridians. ”

Qin Lang's heart moved, and after doing so, a satisfied smile appeared on his face.

It is good to enter the foundation building period, the true yuan in his body is much thicker, and his strength has increased by at least three times compared to the qi training period, and the same fireball technique in the past is now sent out, and the power is much more terrifying.

And with becoming a monk in the foundation building period, the spells that can only be used in the foundation building period naturally increased.

However, Qin Lang didn't have time to inspect it, because with the removal of hair and marrow, his skin was stained with a layer of black dirt, which was the impurities in his body that stuck to his skin after being discharged.

After cutting the hair and washing the marrow, his spirit was also several times better than that of the Qi cultivation period.

Qin Lang went to the bathroom and took a comfortable bath.

Becoming a foundation building monk, if you use the means of cultivating the truth, a fireball technique will pass, and the powerhouses in the later stage of Wuzun will be killed in seconds!

This is the terrifying strength of the foundation building period, and the strength during the qi training period is completely incomparable!

After Qin Lang took a bath, he didn't feel any tiredness, but was refreshed, and with excitement, Qin Lang looked for the memories related to the foundation building spell in Xuan Qingzi's memory.

In the foundation building period, the power of the fireball technique, thunder blast technique, golden thorn technique and other spells used before was naturally doubled, and in addition, there were some new spells.

For example, the fire-attribute spell "Fire Vine Hundred Miles", the metallic spell "Cave Alchemy", and so on.

Although there is no magic weapon in his body, some spells cannot be cast, but as far as the types of algorithms do not increase, it doesn't matter to Qin Lang.

After all, now even the powerhouses of the late stage of Wuzun, he only needs to use a fireball technique to let the other party finish playing, and the spell is used on the body of the earth warrior, and he is still worried that the power is too great.

In addition, in Xuan Qingzi's memory, there was actually a small spell that a foundation building monk could cultivate, and the name was "Perspective Technique"!

As the name suggests, after having a fluoroscopy, the Tsukiji monk can see a lot of things.

Like using perspective, a woman's clothes will automatically peel off in his eyes.

Of course, the reason why he thought of this was also natural for Qin Lang, after all, who didn't want to have abilities like perspective and stealth in their youth?

Qin Lang took a look at the description of the "perspective technique", it seemed that he could not learn until the middle stage of foundation building, although he could not practice it now, but it would only take a year and a half or even less to reach the middle stage of foundation building, and he was not in a hurry.

What made Qin Lang happy was that the stealth technique, which was as famous as the perspective technique, could be possessed immediately!

After becoming a foundation building monk, according to Xuan Qingzi's memory, he could refine a kind of rune paper called an invisibility talisman, so that before the rune paper was used up, his body would be invisible and not seen.

After all, Qin Lang is the aboriginal of the earth, and sometimes he likes to pursue scientific solutions when looking at problems.

However, for the invisibility talisman, he really couldn't find a reasonable science.

According to scientific principles, there is only one way for people to achieve invisibility, and that is to eliminate all the reflected light projected on people.

You must know that others see you and see things because the objects you see are reflected by the light and reflected into the eyes of the people who are looking at them.

For example, in the dark night, the light reflected from the object cannot cause the person's visual cells to react, and the person will naturally be unable to see the object clearly in the dark night.

The reason why animals such as dogs and wolves have much better night vision than humans, and they can see things clearly at night, is because the visual cells of these animals are far more sensitive than humans.

It's not that there is no visible light at night, in fact, there is also light shining on objects at night, the difference is just that human visual cells have limited discrimination and cannot be recognized.

And to be invisible, not to be seen, is to create a normal reflection of light.

To put it bluntly, it is an application of the principle of reflection.

The principle of reflection is used to create blind spots in vision.

It's like the people who don't have a body, the people who are only big, they are reflected in the mirror, and then create a visual illusion: this person is only big, or "invisible".

Like the invisibility cloak that appeared in the movie, the invisibility cloak, is theoretically based on this principle.

Of course, the current scientific research has not yet studied that it is possible to make invisibility clothing to make people stealth.

And the invisibility talisman is a spell that directly makes people disappear out of thin air, and it has nothing to do with the principle of light reflection, Qin Lang wants to find a basis from science, but there is no way.

It can only be said that the cultivation of the true spell is a unique existence.

Perspective can not be learned until the middle stage of foundation building, but as long as the invisibility charm is refined and consumed, you will get the stealth effect provided by this invisibility charm.

Thinking about it, Qin Lang found it interesting.

When I was young, I was more enthusiastic about stealth than perspective.

After an hour, I thought that people could be invisible, so I could knock down the fat classmate who bullied me unconsciously, and I could go to the store and secretly get some snacks I liked to eat.

When I was in adolescence, I thought that if people could be invisible, then they must follow the girl they like home and go to the girl's room to see.

Even if you enter the society, you will think about using stealth, you can become a big hero, go in and out of secret places, hoe and help the weak, and so on.

In short, if people can choose one superpower, they will definitely choose stealth the most.

Qin Lang thought that after refining the invisibility talisman, well, it should be a very fun thing to scare Tang Xue, Ye Xiaorui, and Liu Zhenzhen in the future.

There are many more wonderful uses, obscene ones, just ones, in fact, there are many more.

"Tomorrow, I'll go buy all the materials for refining the talisman, and then refine the invisibility talisman. ”

Qin Lang muttered to himself.

The refining of the invisibility talisman is relatively difficult, and it consumes a lot of true qi, which is the main reason why he can't refine it during the qi cultivation period.

Qin Lang cleaned up and began to sleep.

The next morning, Qin Lang took a taxi to some places in the capital that specialized in selling incense and rune paper, and after shopping there for a full hour, he finally bought all the materials he needed.

When he came back, because the car was in bad condition, the taxi driver changed to another road, which happened to pass through the Nalan family's sphere of influence, Qin Lang just saw a few luxury cars stop, and Li Lengfeng led people and walked towards the depths of the Nalan family.

Qin Lang asked the driver to stop the car, and he got off here.

Now that he has seen this, he will definitely take care of it.
