After selling the pills and array disks in his hands, Xia Chuzhao bought some unburned array disks and array flags, of which the array disks were used to burn and sell for money and research, and the array flags were prepared for going out for tasks.

A month later, there was a big competition among the miscellaneous disciples, but most of the miscellaneous disciples' qualifications were very poor, and it was held every five years, so among these miscellaneous disciples, the cultivation of the fifth level of qi cultivation was the highest.

If nothing else, she can be promoted to an outer disciple this time, and after becoming an outer disciple, she can freely take on tasks to earn resources.

In the past few years, the points and spirit stones she has earned have been used to rub the formations in the sect, if the aura is equivalent to electricity in the 21st century, then the formations are equivalent to those electrical appliances.

The role of the formation is ever-changing, and even an ordinary thing, if different formations are engraved on it, then different functions will appear.

And the reason why Xia Chuzhao and Xia Ruojin cultivated so quickly was precisely because they used the Spirit Gathering Array.

The Spirit Gathering Array can gather the spiritual energy within a radius of a hundred miles at one point, which can speed up people's cultivation, but this requires the spirit stone as the cornerstone, and the higher the quality of the spirit stone, the better the effect of the Spirit Gathering Array.

The quality of the spirit stone is divided into four types: the best, the upper grade, the middle grade and the lower grade, the exchange ratio between each level is 1000, and this spirit stone can not only be used for cultivation, but also the currency of the immortal cultivation world.

As a miscellaneous disciple, Xia Chuzhao only had one low-grade spirit stone per month, and the smallest spirit gathering array also needed seven or eight spirit stones.

As the so-called quantitative change causes qualitative change, Xia Chuzhao came up with an item with a trace of spiritual energy to replace the spirit stone, and their luck was not ordinarily good, just that morning when they were doing the task, the two found a hundred-year-old ginkgo tree in a place.

In ancient times, there was a ginkgo town house to ward off evil spirits, not to mention that this is still a century-old ginkgo that grows in the world of cultivating immortals.

After many experiments and reasoning, Xia Chuzhao really found a way, using some other wood or water attribute items, plus one or two spirit stones, so that a small spirit gathering array could be formed.

Although the effect of this Spirit Gathering Array is a little worse than the lowest level, it is better to be frugal!

I have to say that poverty is the original sin!

However, this also shows that this proves Xia Chuzhao's conjecture that the aura in this world can also be captured by other methods.

At the same time, Xia Chuzhao's success also completely inspired Xia Ruojin's determination to learn mathematics.

may be like most girls, Xia Ruojin doesn't like math very much, and thinks that these X, Y, or anything are very worrying, and every time she sees these numbers, she wants to commit suicide.

Especially Xia Chuzhao likes to give her the kind of chicken and rabbit locked together, how many feet and how many heads there are, and then calculate how many chickens and rabbits there are; Or maybe a pool is filled and drained at the same time, when will all the water be drained?

Xia Ruojin really felt that Xia Chuzhao, who came up with this kind of topic, was simply crazy, the chickens and rabbits were so obvious, couldn't they be separated and then counted?

And if the pool wants to release water, why do you need to fill it? It's just full of food and nothing to do!

However, after Xia Chuzhao successfully used these X, Y, and Z to calculate the combination of formations and invent a new Spirit Gathering Array, she no longer disliked these.

But these are really difficult, and Xia Chuzhao said that the binary equations she is currently learning are the most basic things.

(￣﹏￣(￣﹏￣；)

By the time the two of them finished buying the most basic materials, Xia Chuzhao only had about 90 spirit stones left, while Xia Ruojin only had about 20.

Although they didn't buy much, the shopkeeper of Duobao Pavilion still wiped out the odds, and gave the two of them a wooden card, saying that if they came to buy things again in the future, they could get a discount of eighty or five percent, just hoping that the pills and array plates they made in the future could be sold to Duobao Pavilion first.

In this regard, Xia Chuzhao readily agreed, anyway, where is it not for sale?

Although everything is fully bought, it is the first time for the two of them to come to the market, so they naturally want to go shopping, and they also have a psychology of wanting to pick up the leaks.

Xia Chuzhao knew that his luck as cannon fodder was not good, and he couldn't pick up good things. But there is Xia Ruojin, if there is no rebirth of Su Yunxin, then Xia Ruojin is a proper heroine.

It's just that a ruthless person like Su Yunxin is the "heroine", won't this world be destroyed?

.....

Because the two of them didn't have many spirit stones, they didn't go to the store, but came to the place where the roadside stall was set up.

It's a bustling place, with many monks still hawking, just like the 21st-century stalls.

"The best low-level talisman is on sale, pass by, don't miss it!"

"The freshly picked spirit fruit is sweet and delicious to buy and send to your sister and sister, to ensure that you will be ...... beauty."

"Trifolium, green sunflower, ...... of materials for refining Qi Condensation Pills"

"Fellow Daoist, you see that I have bought so many things from you, can you erase the change?"

"Fellow Daoist, this is a small business, it really can't be cheaper, you see, why don't I give you one more material?"

......

Listening to these cries and bargains, Xia Ruojin only felt extremely strange, "It turns out that people in the immortal cultivation world are the same as mortals~"

Xia Chuzhao waved his hand and said very generously, "Buy whatever you like, there are not enough spirit stones to ask me." ”

Hearing this, Xia Ruojin was immediately ecstatic, but the next second, he heard the other party continue, "It's regarded as a reward for your passing in math yesterday." ”

Xia Ruojin: .....

The smile on his face gradually solidified, and he lowered his head and asked in great disbelief, "Chu Zhao, am I stupid?"

Xia Chuzhao raised his eyebrows and asked, "Who said that?"

"No," Xia Ruojin pouted embarrassedly, "Yes, I think so myself." ”

After five years of study, only this time I passed.....

And Chu Zhao also said that the passing grade is only qualified, not even average.

"Don't be sad. Xia Chuzhao raised his hand and touched her head, comforting, "Although you are very stupid, you have self-knowledge and salvation, like those stupid and self-aware people, that is really hopeless." ”

Xia Ruojin: ......

It was not comforted, but even more shocking!

Many of the stall owners are disciples and casual cultivators of various sects, and many of them have entered the secret realm, or have other opportunities, so many stalls have some strange things.

Xia Chuzhao and the two of them have never been out much, so it is rare to see everything, and Xia Ruojin is very happy to look around along the way.

Although Xia Chuzhao hasn't been out much, she has read a lot of books, so she has read most of the things in books, plus she is an adult, so the curiosity in her body is not so strong.

Suddenly, Xia Ruojin stopped at a stall.

The owner of the stall is a tenth-level Qi cultivator, and this stall is full of all kinds of strange things.

She looked at it for a long time, and finally her gaze stayed on a jade pendant.

At the beginning of summer, Zhao Shun looked at it and found that the jade pendant was transparent and glazed, and there was a faint lilac glow in the sun, noble and elegant.
