The copper wall array and the earth wall array are only low-grade spirit arrays, and the array flags do not need to be refined with spirit silk, but the ordinary silk in the secular world is not good.

Ding Buqun said that he would give Chang Shan twenty sets of materials for refining the array flag, but in fact, there were not so many materials for refining the array flag in Chongtian Fort.

Chang Shan waited in Chongtian Fort for a month, and Ding Buqun collected twenty sets of materials for refining the array flag.

In this month, Chang Shan became acquainted with Ding Haoran a lot, and also saw Chongtian Castle's secret technique Chongtian Ring from Ding Haoran.

The Heavy Heaven Ring is the name of a secret method, and it is also the name of a magic weapon.

The secret magic Heavy Heaven Ring can only be used to trap the enemy, while the magic weapon Heavy Heaven Ring can be used to kill the enemy.

By feeling the power of the secret method of the Heavy Heaven Ring, Chang Shan could be sure that there were at least a star array for cultivating the power of the dragon elephant and a star array for cultivating the power of Xuanwu in the Chongtian Castle.

Knowing that there was a star array in Chongtian Fort that cultivated the power of the dragon elephant and the power of Xuanwu, Chang Shan had the idea of cultivating the power of the dragon elephant in the Chongtian Fort.

After Ding Haoran sent the materials collected by Ding Buqun, Chang Shan began to refine the array flag in the secret room of Chongtian Castle.

Ding Buqun didn't ask Chang Shan what kind of material he needed to refine the formation flag, but the jade silk he collected was an excellent material for refining the lower spirit array flag, obviously, even if Ding Buqun didn't know the formation path, at least he knew that the jade silk was the best material for refining the lower spirit array flag.

"No wonder he didn't ask me what materials I needed to refine the Array Banner!"

Looking at the jade silkworm cocoon in his hand and pondering for a moment, Chang Shan began to compile the array flag.

Refining the array flag for others is different from refining the array flag for himself, after Chang Shan made a formation flag with jade silk, he didn't drop essence blood on it, and directly condensed it with real fire.

After the formation flag was condensed, Chang Shan began to draw the aura of heaven and earth to condense the runes in it.

The difference between refining magic weapons and refining array flags is that refining magic weapons does not need to understand the mysteries of those runes, nor does it need to understand the mysteries contained in the formations composed of those runes, but only needs to understand what the role of the formation is.

For refiners, what they are studying is that smelting those materials together can fully exert the power of a formation.

Due to the frequent study of various materials, the refiner is very sensitive to the materials, and if they are given a method of refining weapons or magic weapons, they can quickly refine them.

It is because of this that many cultivators can refine a certain magic weapon themselves, and in most cases, they will often ask the refiner to help them refine it.

Most cultivators ask a refiner to help them refine weapons and magic weapons, because the speed at which refiners refine weapons and magic weapons is very fast;

Although Chang Shan hadn't survived a single Heavenly Tribulation, his Yuan Shen power was stronger than many cultivators who had cultivated to the Orange Pill stage. Using the power of the primordial gods to attract the aura of heaven and earth to condense the runes in the array banner is not a difficult thing for Chang Shan. For him, the more difficult thing was to familiarize himself with the array flag made of jade silk in front of him.

It took three months for Chang Shan to successfully condense the first rune in the array flag in front of him, and then it took Chang Shan another seven days to refine the array flag in front of him into a formation base of the copper wall array.

After becoming familiar with the characteristics of the array banner refined by jade silk, Chang Shan's speed of refining the formation base became faster and faster.

It only took another twenty days for Chang Shan to refine the remaining seven formation bases.

"It seems that I still have some talent in refining the array flag. ”

Chang Shan smiled slightly, poured a True Yuan into the eight array flags, and then threw the eight array flags out.

The eight array flags flew out more than half a zhang away, and at the same time released a piece of yellow light. After these yellow lights were connected together, they absorbed the aura of heaven and earth, condensing a yellow shield that wrapped Chang Shan in the middle.

Chang Shan shot a True Yuan towards the yellow shield, felt the power of the Copper Wall Array, and said secretly: "If you want to forcibly break this Copper Wall Array, only use the lower grade spirit soldiers, a cultivator in the late stage of the Red Pill will need at least half an hour. ”

After pondering for a while, Chang Shan's mind moved, and eight array flags flew into his hands.

These eight array flags had not been refined, and when Chang Shan was refining them, he inevitably left a trace of his own breath in them, so he was able to withdraw the copper wall array so easily.

If this set of array flags was refined by other cultivators, then it would take a little time for Chang Shan to break through the copper wall.

"Eight jade silkworm cocoons have six hundred spirit stones, and a set of copper wall array flags can sell at least one thousand two hundred spirit stones. In the future, there will be no spirit stones, but you can refine several sets of array flags in exchange for spirit stones. This is probably what my father said back then, with a skill in hand, the world is easy to go!"

After thinking for a while, Chang Shan thought again: "Even if the strength of Chongtian Castle is stronger than that of the Earth Spirit Sect, 12,000 spirit stones is definitely not a small amount for them. Why did Lord Dingbao ask me to help him refine sixteen sets of array flags? Is it of great use? Or is it to exchange spirit stones from other cultivators? Most of the scattered cultivators in the Red Dan stage can't afford to buy formation flags, and the cultivators in the Orange Dan stage can't look down on the upper and lower grade spirit arrays, if they want to exchange spirit stones from other cultivators, who can they sell them to?"

"These things have nothing to do with me, why do I want to do so much?"

Muttering to himself, Chang Shan began to refine the second set of copper wall arrays.

It took almost four months and wasted two jade silkworm cocoons, and Chang Shan refined seven sets of copper wall arrays.

After refining eight sets of copper wall array flags, Chang Shan did not immediately start refining earth wall array flags.

When he was in Juyingtang, Chang Shan fully understood the mystery of the copper wall array, but he did not fully understand the mystery of the earth wall array.

Therefore, it took him nine months to fully comprehend the subtleties of the Earth Wall Array, and then he began to refine the Earth Wall Array Banner.

Although Chang Shan was already familiar with the characteristics of the array flags refined by jade silk, it still took him a month and a half to refine the first set of earthen wall array flags.

After refining the first set of Earth Wall Array Array Banners, Chang Shan also tested the power of the Earth Wall Array.

The power of the Earth Wall Array is comparable to that of the Copper Wall Array, except that the Copper Wall Array has a little stronger defense against spell attacks, while the Earth Wall Array has a stronger defense against physical attacks.

It took another three and a half months for Chang Shan to refine the other seven sets of earth wall arrays that he needed to refine.

Coincidentally, when Chang Shan was refining the first set of copper wall arrays, when he was refining the first set of earth wall arrays, he didn't waste a single jade silkworm cocoon, and when refining the other seven sets of jade silkworm cocoons, he wasted two jade silkworm cocoons.

After meditating for another three days and summing up the experience of refining the array flag, Chang Shan walked out of the secret room.

Guarding the secret room in front of the door of the secret room were the two Dharma protectors of Chongtian Fort who cultivated in the late Hongdan period, and after Chang Shan came out, one of the Dharma protectors walked with him to Ding Buqun's residence, and one of the protectors went to inform Ding Buqun first.

When Chang Shan and the Dharma Protector came to Ding Buqun's residence, Ding Buqun was drinking tea in the living room.

Seeing Chang Shan coming in, Ding Buqun put down the tea bowl in his hand.

"Lord Dingbao, the younger generation is fortunate not to be dishonored!"

Chang Shan bowed to Ding Buqun, and then took out all the five hundred and twelve array flags that had been refined.

Ding Buqun's eyes flashed, first glanced at Ding Haoran who was standing beside him, and then smiled at Chang Shan: "It's hard work!

"Thank you!"

Chang Shan replied with a smile, handed the array flag to Ding Haoran, who walked in front of him, and then sat down in the guest seat on the left.

Ding Buqun took the array flag from Ding Haoran's hand, and first checked it carefully, and then received the storage ring on his hand together.

"In addition to these two formations, does Xiaoyou know other formations?"

Chang Shan smiled bitterly and shook his head slightly.

Ding Buqun nodded, pondered for a while, and asked in a deep voice, "Does Xiaoyou need to meditate for a period of time before entering the Star Array to cultivate?"

Chang Shan's face was happy, he shook his head, and said with a smile: "No need!"

"In that case, Haoran, you take Chang Xiaoyou to the underground palace. ”

"Yes!"

Ding Haoran responded and said to Chang Shan: "Brother Chang, please!"

"Please!"

Chang Shan replied to Ding Haoran, turned back and saluted Ding Buqun, and then walked out with Ding Haoran.

Leaving Ding Buqun's residence, Ding Haoran took Chang Shan to a corner and walked to a rockery.

Ding Haoran clapped his hands in front of the rockery, a rock in the middle of the rockery moved, and a stone cave for only one person appeared in front of the two of them.

Chang Shan followed behind Ding Haoran and walked less than two zhang away to the depths of the stone cave, and then walked to a stone step that went down.

Walking down the stone steps, Chang Shan came to a stone room surrounded by runes.

Chang Shan stared at those runes and pondered for a moment, his heart moved, and he asked Ding Haoran, "Should these runes be used to prevent the spread of star power?"

"Brother Chang has good eyesight!"

Ding Haoran praised Chang Shan and explained: "The spiritual vein under the Chongtian Fort is just a low-grade snake spiritual vein, if you don't use these runes to control the star power in this stone room, the concentration of star power will not reach the current level." ”

Since most of the spiritual veins are in the shape of a snake, some extremely high-quality spiritual veins will give birth to a divine dragon, and in the cultivation world, the spiritual veins are divided into three categories: dragon spirit veins, Jiao spirit veins, and snake spirit veins from high to low, and each category is divided into upper, middle and lower grades.

After explaining, Ding Haoran turned to Chang Shan and asked, "The star power in those star arrays on the Giant Sword Peak must be much richer than here, right?"

Chang Shan nodded and replied, "The star power in those star arrays is not only much richer than here, but the star arrays themselves are much larger than this stone room. ”

After a pause, Chang Shan sighed, "If all the star arrays were placed on the high-quality spirit veins, then the cultivation world would definitely be much more prosperous than it is now." Unfortunately, people have selfishness and greed, and this situation may not appear in thousands of years. ”

Ding Haoran nodded, was silent for a moment, and then left.

After Ding Haoran left, Chang Shan sat cross-legged on the futon in the center of the secret room and began to cultivate.
