In this world, all immortal cultivators use spirit stones to assist in their cultivation.

The faster the efficiency of refining spirit stones, the faster the practice will be.

According to different usages, a low-grade spiritual root cultivator can last ten to one hundred days for a spiritual stone.

In the first ten days, the spiritual stones were refined 40% spiritual energy, twenty days were refined 60% spiritual energy, fifty days were refined 80% spiritual energy, and in one hundred days were refined all the spiritual energy in the spiritual stones.

The efficiency of refining spiritual energy in medium-grade spiritual roots is twice as fast as that of lower-grade ones, that is, it takes five to fifty days to refine a spirit stone, and the efficiency of refining high-grade spiritual roots and top-grade spiritual roots is faster.

Therefore, the key to limiting the cultivation speed of those top-grade spiritual root cultivators has become the number of spirit stones.

That is...

resource.

The annual income of cultivators in the early stage of Qi refining is often only one or two spirit stones, and even the annual income of cultivators in the late stage of Qi refining is only ten. Many cultivators who do not have enough spiritual stones to practice by breathing in the spiritual energy of heaven and earth, and their efficiency has dropped by dozens of times.

Even if the top-grade spiritual root cultivator does not use spirit stones, the efficiency of breathing the spiritual energy of heaven and earth can only be equivalent to fifty days after the lower-grade spiritual root cultivator uses spirit stones.

Of course, the external environment, auxiliary objects, magic weapons, exercises, states, and one's own realm will all affect the specific values.

Liu Chengyuan relied on the Vermilion Bird Qi Refining Method and refining spirit stones at a speed that was no less than that of the top-grade spiritual root cultivator who used ordinary Qi Refining Methods.

Then supplemented by Qi-nourishing Pill...

In a hundred days, he can refine 40% of the spiritual power of a hundred spirit stones, which adds up to 40 spirit stones. Forty spirit stones, it takes five and a half years for ordinary middle-grade spiritual roots to refine them normally.

In other words, the same medium-grade spiritual root has an efficiency of one hundred days that is equivalent to that of other people for five and a half years!

It's the price...

Two hundred spirit stones.

It is enough for a middle-grade spiritual root cultivator to practice for nearly 28 years.

If he can really complete these hundred days of cultivation, the door to the third level of Qi refining is equivalent to being open to him.

Everything is ready, just spirit stones are missing.

...

When Liufu went to drive the car, an old man brought five people to Liu Chengyuan's yard.

Among the six people, the middle-aged man came forward and greeted him meticulously: "Young Master."

"Butler Yuan, Yuan Feng."

Liu Chengyuan looked at his housekeeper, the chief guard.

The housekeeper is named Yuan Hai. Although he is of the same surname as Yuan Feng, he has nothing to do with him.

Among the two, Yuan, the sixth floor of Qi refining, Yuan Feng, the chief guard...

Qi refining seventh level.

A late-stage cultivator of Qi Refining.

In the later stage of Qi Refining, he was a person with status and weight in Bai Yuliu's family. Even as the eldest son, he could not enjoy such a guard.

but……

As the head of the Baiyu Liu family, Liu Fengxue arranged a guard at the peak of the sixth level of Qi refining by his side, and gave him resources to help him break through the seventh level of Qi refining.

It was also because of this kindness that Yuan Feng had no complaints about Liu Chengyuan driving him away first and then recalling him.

"I will leave it to you myself and the safety of the yard."

Liu Chengyuan said cautiously.

Yuan Hai and Yuan Feng looked at each other and nodded at the same time: "Please rest assured that we are here, we won't let the little devils hurt you at all."

"Okay, I'll give you an important task."

Liu Chengyuan brought Yuan Feng, Yuan Hai and his six people to the inner courtyard, pointing to the nuclear trajectory that still weighs a lot of flowers and plants so far: "Move it to the side hall and guard it day and night, and no one is allowed to step into the side hall."

The two of them looked at the nuclear bomb in the yard and were a little surprised.

A man behind him changed his face instantly.

This change made Liu Chengyuan's eyes quickly fall on him: "Do you know this thing?"

"No...I don't know it, but I have reached the third level of heaven for practicing Tianji. Under the sensing of Tianji, this thing... seems to contain great danger, just like... the scorching sun in the sky, making people feel anxious..."

The man's face turned pale.

"Tianji Technique? The third heaven's Tianji Technique!?"

Liu Chengyuan's eyes suddenly changed.

Good guy!

The Tianji technique of the third level is even rarer than that of the late Qi Refining monks. When you enter the Inspection and Heavenly Palace, you can be in charge of at least the first floor and become the owner of the landlord. If you make a contribution, it is not difficult to become the vice-chancellor of the Inspection and Heavenly Palace.

Such a person actually came to be his guard?

Is this the treatment of the eldest son?

"Mr. Yuan, this thing... is dangerous. I suggest that Mr. Yuan stay away."

The man said nervously.

Tianji warned him to escape as soon as possible.

"You are called... Fang Daoyan?"

"yes."

"I am quite interested in the magic of heaven. Can I teach me the magic of heaven?"

"This... the young master has a broad future, and he should not focus his precious time on the boring study of Tianji."

"It's okay. I heard that the secrets of heaven can deduce opportunities and even predict good and bad luck. If I can practice it, at least I will have more guarantees."

Liu Chengyuan's way.

In this world, a powerful person once opened up the realm of heavenly secrets, recorded all the information that could be followed, and passed down the sixteenth level of heavenly secret deduction techniques, allowing the originally mysterious and mysterious deduction techniques to flourish.

Any Tianji monk who practices the deduction technique of Tianji can be guided by a little bit of clues derived from the Tianji world that contains countless information.

Those who practice the Heavenly Secret Art to the Tenth Level of Heaven can also open up small realms from the Heavenly Secret Realm, for people to communicate, help others deduce, share information, and even erase the Heavenly Secret Realm for others.

Of course, the price is very expensive.

"Oh well."

Fang Daoyan responded helplessly: "However, practicing the deduction technique of Tianji requires the use of corresponding magic tools..."

"I just happened to go out to sell Yuancheng and buy it together."

Liu Chengyuan's way.

At this time, Liufu had already driven Yuan Cheng to the door and came to ask for instructions.

Liu Chengyuan glanced at the hydrogen bomb and told him carefully: "Master Yuan, I will leave this item to you for your care."

After saying that, he focused on the operation area: "Don't let people touch this area at all!"

"Don't worry, Master."

Yuan Feng looked at some unknown words in that area and said in a deep voice: "I will guard this thing with my life."

Liu Chengyuan nodded.

In the late stage of Qi Refining, he was already a figure in Baiyu City.

The masters who look at the storefronts of several major chambers of commerce in Baiyu City are often at this level, even the Lin Chamber of Commerce, the number one in the city, is no exception.

Liu Chengyuan came to the door.

The wind-chasinger Yuan Cheng was already waiting at the door.

modeling……

It feels like a Harmony EMU front, but it looks even more compact and exquisite.

There were still many people on the street looking at this Yuan Cheng, full of envy.

However, the yard bought by Liu Chengyuan is in the core area of ​​Baiyu City. At first glance, the houses are grand, the environment is elegant, the streets are neat and there is no slight mess.

The pedestrians who come and go are also dressed beautifully, either rich or noble, so they will not lose their composure to watch.

Liu Chengyuan got on the Yuan Cheng, stepped on the luxurious carpet under his feet, and the decorations on both sides were full of craftsmanship.

In addition, this 4.6-meter-long shaft is divided into two layers, front and rear. The driver is located in front and the space is relatively small, but the rear layer is quite spacious. The two seats can be completely lowered and connected to the rear seats to form two single beds, and can also be merged.

"The designer of Yuan Cheng... understands it very much."

Liu Chengyuan touched the seat with a very textured texture: "Although this world is an ancient background, a city where immortals and mortals live together cannot be treated as the previous impression."

...

How huge a city with a population of tens of millions is, and what amazing productivity it requires, transport capacity can supply the daily consumption of tens of millions of people.

These are symbols of background.
