Early the next morning, the Zhu merchant group left Heiquanji. Because some sand bandits were subdued during this time, the team that came out was still slightly stronger.

The direction in which they are moving forward is to continue deep into the "Mingsha Valley" of the desert.

In the desert, the place where monks are most concentrated, there is a high cave mountain in the east, a white camel mountain in the west, and ten oases, seventy-two valleys, and eight hundred springs.

If the desert is divided into areas according to the strength level of the gathering place, the first layer is the edge of the desert, and the active ones are Qi cultivation stage cultivators, and even some mortal warriors can survive here.

The second layer is a place like the Black Spring Collection, which has officially entered the desert, but it is not deep enough, and the foundation building monks are already the top force here. There are more than 800 settlements like the Black Spring City Walled City in the desert.

The leader of the third layer of power has to be a Jindan period monk, and the destination of the Zhu family's merchant group, "Mingsha Valley", is one of them, and there are a total of seventy-two settlements at this level.

The fourth layer is the hinterland of the desert, where large forces are entrenched in the desert, and it is said that there are twelve in total.

The fifth layer is a super-large settlement, which is distributed in the east and west of the desert, which are the high cave mountain in the east and the white camel mountain in the west.

And in the core of the desert, there are some forbidden places that monks cannot set foot in, and it is said that even the Yuanying monks have fallen in it.

The current leader of the Zhu Clan's business group is Xu Fu, how to choose a route, how to exterminate and subdue the sand bandits, how to find a station, how to avoid the beast group sandstorm, these are all things that Xu Fu has to worry about.

In this way, Zhu Youdao is very comfortable.

He and Li Yunniang hid in the huge beast cart to cultivate, read, play chess, study the formation path, etc., except for occasionally coming out to check the progress of the disciple clan's cultivation, he would never step out of the beast cart.

At this time, Zhu Youdao was holding a roll of animal skin paper and carefully studying something, while Li Yunniang was staring at a formation plate, and from time to time he moved the small flags on it to deduce the changes in the magic circle.

After a long time, Zhu Youdao said: "I didn't expect that Jin Wuda still has this kind of treasure raising secret technique in his hands, when I was in the Vientiane Secret Realm, from the inheritance of the Yashan Sect, I also saw a kind of treasure refining secret technique to speed up the growth of magic weapons, but unfortunately at that time, building Kievan was more important to us, so I gave up the treasure alchemy secret technique, I have been regretting it all these years, and I plan to let the children at home try it when the Vientiane Secret Realm opens again!"

Li Yunniang looked at it when she heard the words and asked, "Is it the secret technique of cultivating magic weapons?"

"Yes, this secret technique is called 'Blood Spring Sword Cultivation Technique', which is a secret method for raising treasures in a different way, but it is also very restrictive, and it can only cultivate magic weapons such as swords.

This kind of secret technique needs to be combined with alchemy, with the blood of high-level demon beasts, supplemented by a variety of precious spiritual herbs, refined into a special spiritual liquid, and in using this spiritual liquid to refine the sword, you can slowly improve the level of the magic weapon!

For example, the Flying Knife I used to use, even if many people relay and practice uninterruptedly, it will take twenty or thirty years to refine from the magic weapon Yuan Fetus Sacrifice to the first-order peak magic weapon; to refine to the peak of the second order, it will take a hundred years of hard work; it will take five or six hundred years to refine to the peak of the third order!

In fact, monks spend most of their time improving their cultivation, so how can they have so much time to practice magic weapons?

But with this kind of treasure cultivation secret technique, as long as you take a little time to practice with spiritual liquid every day, the magic weapon can slowly increase its level, saving a lot of time!"

Seeing Zhu Youdao with a look of joy, Li Yunniang asked, "Since this secret technique is so precious, how can Jin Wuda be willing to exchange it for you?"

Zhu Youdao said with a smile: "This kind of secret technique is extremely precious to us, but for the Jinsha Gang, it is actually a chicken rib!"

There are dozens of spiritual herbs needed to refine the spiritual liquid of the magic weapon, and most of them are not produced in the desert, so they can only be purchased through foreign caravans, and the price is ridiculously high!

Jin Wuda's long knife has not yet reached the second order, and it almost makes the entire Jinsha Gang unable to afford it! Therefore, without strong financial support, this kind of treasure raising secret technique is just a look!"

Li Yunniang nodded: "What did you get it for?"

"A promise!"

"Promise?"

"Yes, Jinwuda made me promise to help him explore an ancient monk's cave in a few years!"

"Then this cave must be very important to him!"

"Yes, Jin Wuda has already said that this cave is related to his knotting, and the 'Blood Spring Sword Raising Technique' was obtained in that cave, and in that exploration, Jin Wuda's father, grandfather, uncle and other blood relatives all paid the price of their lives! According to his description, I concluded that the cave house has a powerful magic circle to protect ......"

Zhu Youdao and Li Yunniang chatted about the secret technique of raising treasures for a while, and then heard Xu Fu say outside: "Lord, there is another team of sand bandits who are ready to attack us, and we have to bother the master mother to take action!"

This is the practice of the Zhu family's business group, Li Yunniang's cultivation needs to kill, and she mainly solves the problem when she encounters sand bandits.

Zhu Youdao nodded, and Li Yunniang got off the beast cart and went to kill the sand bandits.

After she left, Zhu Youdao studied the "Blood Spring Knife Cultivation Technique" for a while, and then put it away and began to cultivate.

The merchant group walked in the yellow sand for a month, and encountered many troubles during this period, which were solved by Xu Fu and others.

During this period, Zhu Youdao walked out of the beast cart a few times, but was still pulled by Li Yunniang to see the moon in the desert.

On this day, Zhu Youdao was talking to Li Yunniang about the matter of the magic array, and only heard Xu Fu report outside the car: "Lord, our business group may be targeted, in recent days, there are people secretly peeping, and today there are even scouts of sand bandits blatantly roaming around, obviously they are about to make a move!"

Zhu Youdao pulled the curtain and said: "Along the way, we have destroyed no less than ten sand bandits, and we have already spread some reputation in the desert! The ordinary sand bandit group not only did not dare to trouble us anymore, but wanted to avoid us. The sand bandits dared to attack us this way, they must be very confident in their own strength!"

Xu Fu bowed: "Yes, among the sand bandits we subdued before, some people pointed out that the scout's costume seems to be a person from the famous sand bandit group 'White Sand Pirate Group' who is active in the desert!"

"White Sand Pirates?"

"Yes, I have collected some information, there are nearly 100 members of the core main battle of the White Sand Pirate Regiment, and the weakest ones have the middle and late stages of Qi training, and each of their members is riding a white sand wolf, coming and going like the wind in the desert, and it is difficult to find their whereabouts. Its head is said to be a monk of the Jindan period, and there are many monks under his command......"

"There is a Jindan monk!" Zhu Youdao nodded, "Then we have to entertain this White Sand Pirate Troupe well! It just so happens that Yun Niang and I just researched a set of magic circles some time ago, and the power is not bad! Xu Fu, you see what terrain is easy to defend and difficult to attack nearby, let's station down first, and wait for them to do it!"

Xu Fu thought for a moment and said, "According to the map we collected, adjust the direction and walk for two hours, there is a Zhuma Pass, where passing merchant groups often hide from sandstorms......"

"Okay, notify the merchant group, go full speed, and set up camp after arriving at Zhuma'ao!"

Half a day later, the Zhu merchant group was stationed in Zhuma'ao, and Zhu Youdao first sent people to arrange a magic circle outside, covering the station with wind and sand, so as not to be seen by the scouts of the sand bandits.

Then Zhu Youdao summoned the Zhu family, the core of Yuxiu Sect and Shenxiu Sect, and ordered: "There are powerful sand bandits coming, we have to prepare early! You obey Yun Niang's command, cooperate with her to set up a magic circle, let's let the sand bandits attack!"

Everyone listen in unison!

Zhu Youdao took out sixty-four array flags, asked each person to take a few, and followed Li Yunniang to set up the formation.

Zhu Youdao liked to watch "Romance of the Three Kingdoms" in his previous life, and he once saw a kind of military formation in it, called "Eight Gates Golden Lock Array". He liked to study these Shinto things, and he studied them at the time.

Although he has forgotten all these years, the monk's memory is very magical, and even if he forgets something for a long time, as long as he thinks about it deliberately, he can still remember it slowly.

Zhu Youdao recalled that after the Eight Gates Golden Lock Array, he studied it himself, but he didn't come up with any famous names, so he drew this gate array and handed it to Li Yunniang to see.

Li Yunniang was very interested at a glance, and whenever she had spare time, she took out the formation diagram and slowly deduced it.

Later, according to the principle of the formation path of the cultivation realm, she slowly figured out some doorways, and asked Zhu Youdao to refine a set of formation flags that were specially applicable to this formation, and deduced and practiced the specific application of this formation.

It took twenty or thirty years before the method of using this array was successful.

Because the formation diagram has already involved the operation of the cultivator's formation, it is no longer a mortal military array, Zhu Youdao named the magic array "Eight Gate Lock Immortal Array"!

Some time ago, they also did an experiment, laying an eight-door lock immortal array in the sand, after Zhu Youdao himself entered the formation, he only came out in three days, this is still Li Yunniang did not manipulate the changes of the magic circle, otherwise he would not be able to get out in his life!

And to forcibly break the formation, Zhu Youdao invited Sun Wudao and Lei Kedun to do the tests respectively.

Sun Wudao has only been in the Dan for a few years, and its combat power is equivalent to the early stage of Jindan, and it has not attacked this formation with all its might.

However, Lei Ke Dun, a demon general in the late stage of the third order, had tried his best to attack for a quarter of an hour, and the Eight Door Lock Immortal Array was already in danger!

But if someone is holding it back when it is attacking the formation, and then changing the formation to run the formation gate, it will not be easy for Lei Ke Dun to forcibly break the formation.

Lei Kedun is equivalent to a monk in the late stage of Jindan, even he can't forcibly break the formation in a short time, Zhu Youdao believes that if the leader of the Baisha Bandit Group had this ability, he would not be a bandit.

Under Li Yunniang's deduction, the Eight Door Lock Immortal Array is composed of eight array gates, each array gate is equivalent to a small magic circle, and each small one is composed of eight array flags.

This array requires a total of 8864 array flags to be arranged.

Zhu Youdao made a bloody investment for this, and the grade of each array flag was as high as a second-order, which was equivalent to a second-order magic weapon.

The spirit stone that supports the operation of the magic circle, Zhu Youdao gritted his teeth, and used a high-grade spirit stone.

Every day that this array operates, it will get eight high-grade spirit stones, and the consumption is not small.

But it is worth it to let the monks of the foundation building period fight the golden pill according to this formation.
