Fifteen days later.

At night, in a dense forest in the mountain behind the Hidden Dao Sect, Chu Ling sat on a towering tree with his eyes closed, and at this moment, in his mind, a simple Heavenly King Holding Mountain Seal was already clearly visible, emitting a glittering golden light.

Suddenly, the imprint of the last corner was also carved out by Chu Ling through gritted teeth, and the light of the formed ancient seal suddenly doubled, and when the golden light dissipated, the ancient imprint was also quietly suspended in his mind.

"Whew!" Chu Ling exhaled a long breath, it was finally done, after three months of practicing day and night, the Heavenly King Holding the Mountain Seal had finally achieved something.

"Not bad!" Ning Tianshi floated out of Chu Ling's mind lightly, hovering above his head, and exclaimed implicitly.

Ning Tianshi didn't seem to be sad or happy, but he was extremely pleased to touch his beard, this son was able to condense the first dragon seal within fifteen days, although he had the support of the previous foundation, but it also showed talent, the most important thing is that this son worked hard to be twice as hard as ordinary people, this is the key to the improvement of the Great Dao!

Ning Tianshi nodded slightly and said, "You have now condensed the first dragon seal, but in order to become a real dragon seal wrestler and transform the dragon seal into combat power, you also need to cross the underground dragon qi into the dragon seal!"

"When subduing the underground dragon qi, the most important thing is to trap the formation of the underground dragon qi! So in the next time, I will teach the art of carving the formation, every successful earth dragon master, he must first be a formation master!"

Formation Division!

Hearing these two words, Chu Ling's whole body was full of blood, and the formation master and alchemist, as the most mysterious professions on this road, were sought after by all the major sects and holy places.

Naturally, the alchemist didn't need to say much, and compared to the famous alchemist, the formation master was much more low-key.

However, the daily maintenance of the sect's mountain protection array, the daily maintenance of the inter-sect teleportation array, and the various escape formations used to escape a life at the moment of life and death are all inseparable from the formation master, and an excellent formation master can stir up the wind and clouds no matter where it is placed on the mainland.

The classification of formation masters is the same as the classification of cultivation, and it is also from the Juyuan level all the way to the Great Sage level.

However, the formation master is extremely low-key, and the inheritance is extremely strict, and the master and apprentice pass it on by mouth, and the secret method is not passed on to the six ears.

Therefore, a formation of Dao everyone, basically a few disciples in a lifetime, may not have a single one with extremely strict vision, and can only watch their own mastery drown in the dust!

So this leads to the extreme scarcity of formation masters, but it is precisely because of the scarcity that they are precious!

Ning Tianshi continued: "Formations, according to types, are mainly divided into two categories. The first is to use the blood of demonic beasts or other spiritual things on the ground to engrave a formation, which is called a landing formation.

In addition to breaking it with force and waiting for its aura to dissipate and naturally disintegrate, the landing array has almost no flaws, but the disadvantage is that it cannot be easily moved.

Another way to arrange the formation is to engrave the array plate, the array platform, or the sacrificial array flag and other magic weapons used for the formation in advance, and arrange them according to a certain position at a critical moment to exert their power!

The Sleepy Dragon Breaker uses the Star Luo Array, so you learn the Star Luo Array first, and before you officially learn the Carving Array, you first go and buy some Array Discs and Spirit Cone for the Carving Array and come back!"

Chu Ling's brows couldn't help frowning, the materials needed to carve the formation were purchased with a large number of spirit stones, and Chu Ling, as an outer disciple, had no savings at all.

The scarcity of the number of formation masters, in addition to the reason why the formation masters are harsh in their selection of apprentices and the disadvantages between portals, are also inseparable from the huge resources required to train a formation master.

At this time, his cheap master seemed to have grasped Chu Ling's difficulty, and laughed hesitantly......

Three days later, not far from Jiuzong Mountain, the first male city on the northwest border of the Shentang Empire, was in the Axe Mountain City.

Huge and spacious street people come and go, bustling and lively, under a huge archway in the city, a thin figure with a hemp robe to cover the face of the strict thin figure stopped here, hesitated for a while, resolutely walked in, and on the huge archway, "Marbaotong Tianxing" five big characters shining in the sunshine of the golden light......

"Boss!"

An old voice sounded in the store of Wanbaotong Tianxing, Chen Erhai quickly twisted his fat body and sat up from the recliner, he was quite resentful of being sent to this remote branch as a shopkeeper because he had just made a small mistake, but he put out a kind smile according to his profession.

"Welcome, officer, I don't know what you need?"

"Boss, I'd like to change something here with you!" said the old voice unhurriedly.

"Oh!" Chen Erhai clearly heard the change of words, Wanbaotong Tianxing business is very large, and it is also engaged in acquisition business, and most of the people who come to the door are people like this who are unwilling to reveal their identities, Chen Erhai also knows not to inquire about the origin of this old man in linen, and said bluntly: "I don't know what Mr. wants to exchange? What do you want to exchange?"

"Refreshing!" the old man in the linen robe exclaimed, took out two thumb-sized small stones like inferior citrine from his arms, lined them up on the counter, and asked with a grin, "Is this enough?"

Chen Erhai raised his mung bean-sized eyes, picked up the two small stones in his hand and looked at them carefully, an unbelievable horror climbed up his cheeks, his breathing gradually became rapid and said in a trembling voice: "This is ......"

The black-robed old man nodded slightly, Chen Erhai saw that no one on the left and right hurriedly put it in his sleeve, stretched out his hand and made a gesture of please: "Please also talk about it in detail sirs!"

In the attic on the second floor of Wanbaotong Tianxing, Chen Erhai and the old man in the linen robe sat down as the guest of honor, and a cup of hot tea was served.

Chen Erhai took the lead and arched his hand and said: "With all due respect to Chen's bluntness, the items that Mr. used to exchange this time are too incredible, and I am just a branch under the Wanbaotong Tianxing Shentang Empire Branch, and I may not be able to let Mr. get something satisfactory, but if Mr. is not in a hurry, Chen has the courage to be the master, and I will do my best to meet Mr.'s requirements when I take over this business." ”

Although Chen Erhai had tried his best to suppress the excitement in his heart, his voice was still faintly trembling.

"It's okay!" the linen-robed old man waved his hand casually, "I need a dragon tooth engraving cone and a hundred sets of Dao Plates for practice! and a superb soul solid pill!

Chen Erhai's eyelids jumped hotly, and he said happily: "Mr. turned out to be a formation master!" As soon as the words came out, he realized that he was indirectly inquiring into the identity of the guest, and held his forehead with one hand to express his apologies.

The old man in the linen robe stopped and said, "It doesn't matter if you know, it's all for my unsuccessful disciple!"

Chen Erhai nodded in understanding and said, "It's just that these two treasures are too difficult to find, and it is more than enough to exchange these two things, I don't know if Mr. has any other requirements?"

The old man in the hemp robe nodded and said, "I also want a piece of Qiyan Stone on Phoenix Island and colorful glazed sand from Zulong Prefecture!"

"Hiss!" Chen Erhai gasped, as an old shopkeeper of Marlboro Tianxing, he naturally knew what the meaning behind these two things was! These two things were also the things needed to carve a high-level formation pattern, but it was not a formation master above the Venerable Realm, not to mention using it to copy the formation pattern, and it was difficult to even leave a trace on it.

But the old man continued without raising his head: "Although these two things are rare, but when the old man was in Middle-earth in his early years, he heard that Tongtian Trading Company had stations on Phoenix Island and Zulong Prefecture, and it should not be difficult for you to come to these two things! As for the price, you don't have to worry!"

Chen Erhai nodded curtly, a shrewd light flashed in his eyes, and he returned the two dim stones and said loudly: "Since the old gentleman is so refreshing, Chen also has the courage to call the shots, you take these treasures back first, and all the things you need in the small shop will also be taken away first, and after half a month, the remaining things will be presented together, and then we will retrieve these two treasures from Mr. ”

"In addition..."Chen Erhai paused, clapped his hands, and a pretty woman walked up with a professional smile holding a sandalwood box. Lying quietly in the box was a gleaming golden card.

"Since Mr. is a formation master, Chen Mou doesn't want to ask Mr. to accept this golden VIP card, because the level of the small shop is not enough to issue a gold VIP card, this is Chen's usual private use, and I hope that Mr. will not dislike it, in the future, all the materials that Mr. needs to copy the formation pattern, we will prepare three times, but as long as you send us a set of the same formation to Tongtian Commercial House afterwards, I don't know what Mr. wants?"

The old man nodded silently, took the golden VIP card without care, and walked out of the Marbuchi Tianxing without looking back, with a cone stuffed with a copy of the Dao plate and a dragon's tooth engraving cone......

Seeing the nameless old man leave, Chen Erhai quickly walked into a secret room, three spars pressed into a tabletop-sized communication array, cyan light flashed, and an old man dressed in gorgeous clothes appeared in the center of the communication array.

"Xiao Hai, what's the matter with me!" the old man smiled kindly.

"Teacher, there are primordial soul crystals in my store today, or two!"

"Oh, it's a soul crystal!" the old man touched his beard and smiled, and then suddenly came to his senses: "What do you say? soul crystals? Or the primeval period? Impossible, soul crystals are not as stable as bone crystals and blood crystals, if they are primeval periods, they can't be left at all!"

Chen Erhai smiled bitterly, helplessly looking at his teacher, who was shocked into a cold sweat, how could he not react like this when he saw it for the first time? The Ancient Soul Crystal, which has been passed down for millions of years, not only has a great temptation for the spiritual masters above the Dragon Cutting Realm, but it is also too unbelievable.

Chen Erhai had no choice but to tell the truth of the matter.

The old man touched his beard and nodded slightly in admiration: "Xiao Hai, you are doing a very good job, in my opinion, that old gentleman is definitely not only at the Venerable level, the peak of the Dragon Cutting Realm or the Emperor Realm is unknown, you must not neglect the distinguished guest!"

"Hmm!" Seeing that the beloved disciple was gradually on the right track, the old man in gorgeous clothes also smiled and squeezed the folds and said: "Xiaohai! you made a mistake and sent you to such a far place for the teacher, you have done a good job this time, and you will come back when this matter is over! When the time comes, I will push you to the vast and boundless world of Middle-earth, and the young man should also have a good look at the prosperity outside!"

Chen Erhai smiled excitedly and thanked him again and again, and he faintly felt in his heart that his life would be changed because of that mysterious 'old man'......
