Shi An sat on the chair and pondered, smelting this material that no one else could do for the second son, his gratitude to himself was very sincere, which was fully revealed from Wu Wei's clear eyes, but this still did not allow him to allow himself to enter and leave Wu Luobao freely.

It seems that this is not that the second son does not want to help himself, but it must be an iron law in the castle. Then if you want to enter and exit Wuluobao freely, it will not work, then the next way is to take the opportunity to enter the Tibetan Scripture Pavilion more than a month later to enter the inner gate, to see if you can find out the archway formation at the entrance of the sect, or to find out if there are other secret passages that can enter the inner door.

In the cave stone, Shi An was once again immersed in reading the jade slips. "The Continuation of the Essentials of Formations" has been read in full, including the common formations of the middle and advanced levels, and he has also memorized and deduced them many times. But like the Wuluobao archway, the formation that directly sacrifices thunder and lightning is not introduced in the jade slip, but there is a very similar formation.

This is a high-level formation called "Mixed Yuan Array", as far as Shi An knows, except for the intermediate formation of the "Qiankun Enchantment" in the Prison Tiger Cave in the Four Elephant Temple, other intermediate and above formations have not been seen in this realm, and even the formation level is very high, and there are only a few intermediate and high-level formations.

Shi An suddenly thought that if the Four Elephants, the Jihai Sect, and Wu Luobao were all built by one person, then it was not impossible for a mid-to-high-level formation to appear, and the ancestor of the Three Sects must also be a formation master.

Looking carefully at the introduction of the "Mixed Yuan Array", Shi An found that except for the thunder and lightning attack launched on the archway, and the Mixed Yuan Array launched the Five Elements Spell Attack, the rest of the attacks such as the trigger state and attack range are exactly the same. The spirit source of the mixed element array relies on attribute spirit stones, and using different attribute spirit stones will produce different attack spells, so what if the spirit source is placed with thunder spirit stones?

Thinking of this, Shi An suddenly had a realization, yes, it must be the transformation formation of the mixed yuan array, and the spiritual source must also be the thunder spirit stone. But after thinking about it again, Lei Lingshi himself was also completed with the help of the Spirit Gathering Array under the prompting of the well-informed An An, so where did the ancestor of Wu Luobao get it?

Regardless of this, it is imperative to study how to break it.

Shi An clearly remembered that the method of breaking the mixed element array in the jade slip was to first resist with a spell that matched the attributes of the formation, until it could reach the vicinity of the formation eye, and only need to use the boundary array disk to open the formation, and if the spirit source could be removed, the formation would be paralyzed immediately.

This method of cracking is not difficult to understand, the difficult thing is that the attributes of the five elements all have attributes that can be restrained, and what the attributes of thunder are Shi An does not know, let alone use the spell of restraint to resist. So although there is an idea to crack it, there is no way to crack it.

The only thing you can do after entering the inner door is to look and see if there are any other ways to enter.

In fact, Shi An did not wait for the outer disciple to enter the inner gate more than a month later.

On the fifth day after taking away Shi An's smelted Lei Qi throat and the water and fire dual-attribute lancet, Shi An followed Wu Wei into the inner gate of Wu Luobao.

"Senior Brother Zhao, I told the castle lord about your situation four days ago, the castle lord is very concerned about you, let me take you into the inner gate today, he wants to meet you. Early in the morning, Wu Wei went to the hardware store and said this to Shi An.

Shi An was stunned in his heart after hearing this, a castle master would personally meet an outer disciple, which he had never expected. What could be the reason, is it because his refining skills have reached the level that even the castle master is amazed? Shi An shook his head secretly, he was not so narcissistic. There must be other reasons, since I can't figure it out, I simply don't think about him.

The two walked and chatted all the way, and when they saw that they were about to reach the mountain gate, Shi An remembered the archway that would be struck by lightning, and his pace couldn't help but slow down.

Wu Wei saw Shi An's very nervous expression, smiled slightly, handed him a jade plate and said, "Don't be nervous, you only need to put the waist card in the storage bag now, and then hold this thing to get started." ”

Shi An took the jade card and looked at it carefully. This is a yellow jade plaque two inches wide and one inch long, which is only engraved with the three seal characters of "Ke Mao Zichen", and there is no other pattern. According to what Wu Wei said, he removed the waist card and held the jade card, and cautiously approached the archway.

It was easy to step over, and there was no lightning strike. Shi Anzhong moved, and released his divine sense to observe the archway and the formation on the archway, and when he was less than a foot away from the foundation pillar of the archway, his divine sense was like being pricked by a needle, and suddenly there was a sharp pain at the sea of knowledge, and he snorted unconsciously.

Seeing this, Wu Wei smiled and said to him: "If I were you, I wouldn't use my divine sense to see that archway." There is a formation on the archway, there is an identification function, recording the existing breath of all kinds of waist cards, and for the existence of the breath that is not its acquiescence, it will directly send out a thunder strike. So if you don't have this jade card in your hand, don't say look, you will be killed by lightning within ten zhang of the archway. This jade plaque is for the guests who come to the fort, there is no obstacle in entering and exiting the mountain gate, if you use your divine sense to watch the mountain protection array, although you will not be attacked by the thunder and lightning of the formation, but you will also be punished by the formation. You must know that it is very rude to observe the mountain protection formation of his sect, and the punishment of my fort is light. ”

As soon as Shi An heard this, he broke off the idea of continuing to investigate. After thinking about it, I took out my own waist card to compare, the same material, the same size, and the same engraved font, so why is there such a difference?

"Hehehe, don't you think it's strange? The difference between these two signs is the inside, you can use your divine sense to see them separately. Wu Wei prompted.

Shi An probed his divine sense into the two jade plates, and then he suddenly realized: the two jade plates contained a divine consciousness, the waist card and the jade plate were completely different, indicating that the identity of the holder was an outer disciple and a visitor.

Putting the divine sense into the jade slip, as long as the monk can read the jade slip, will do this, but placing the divine sense in the jade tablet as a way to identify the identity of the holder, Shi An has seen it for the first time. It seems that the use of divine consciousness is not only as simple as reading, probing, and imperial objects, but also has many uses if you think about it carefully.

"Okay, you should return that jade plate to me, and you won't need it when you go out in a while. ”

The aura inside the fort is far from comparable to the outside, and the further you go inside, the stronger the aura concentration becomes. According to the introduction of the second son, the mansion of the castle lord is in the center of Wuluo Fort, and it is also the place where the aura is the strongest.

The two of them walked on the central avenue, and Shi An quietly released dozens of divine senses as he walked, and slowly sneaked into various locations in Wuluobao to check. The exploration range of more than 150 miles is the limit of his current divine sense, which can basically cover the entire sect, but he is still very careful, and he does not dare to easily probe his divine sense directly into those caves with strong spiritual energy, he knows that the better the residence, the higher the cultivation of its owner, and the more likely it is to find his voyeurism.

When they walked a few feet away from the castle lord's mansion, a fierce quarrel came from the mansion and interrupted the conversation between the two of them.

Just when the two of them were surprised who dared to quarrel with the castle lord so boldly, a black fat man rushed out of the door, still shouting: "If you let me go, I will go, if you don't let me go, I will go!"

The second son, Yi Shi An, let him go to the side of the road, bowed down and saluted, "Hello, big brother." ”

When Shi An heard this, he knew that it was Wu Jian, the eldest son of Wu Luobao, and he hurriedly bowed down, but did not speak.

When Wu Jian passed by the two, he did not return the salute, but glanced at Wu Wei with slanted eyes, and the word "hum" came out of his nostrils, which was regarded as an answer to him.

After he walked away slowly, Wu Wei got up and introduced to Shi An: "This is my eldest brother just now, he usually looks like this, don't care." ”

"Look at what you said, I'm a little outer disciple, how can I care if I don't care about it. Shi An said. However, from Wu Wei's words, Shi An can also see that the second son respects him very much, although his status is very humble, which also moved him very much.

"Xiao Wei, come in. An old, slightly tired voice came from the mansion.

"The lord of the castle is calling us, so let's go and see us. Wu Weiwei pulled Shi An, who was still pondering.
