Lu Yun scolded with a smile: "Now that the master is by your side, you will naturally tell you everything, and you will be alone in the future, who will tell you?" Remember what happened to Tiger Shark Ridge? At that time, with your strength, you shouldn't have been attacked by the blood spirit at all, but you were too careless. ”

The sea girl's face turned red, and she said coquettishly: "Master, the sea girl is still young, don't talk about it." ”

Seeing her appearance, Lu Yun couldn't help but hug her and said lovingly: "The master is teaching you experience, although you are only four years old, but you are different from ordinary people, if you want to be famous in the world, you have to study seriously, you know?" ”

The sea girl hugged Lu Yun's neck and said coquettishly, "I know, master." Let's go. ”

Lu Yun shook his head and smiled, a little relieved, a little touched, as if his thoughts had returned to the past.

Leaving the stone castle where the black charm was, Lu Yun led the sea girl into the second stone castle on the left. The exterior of this place looked no different from the stone castle before, but after Lu Yun entered, he found that the inside was completely different.

As far as Zhang Aoxue had seen before, there had been many demon sharks gushing out here for no reason. Now Lu Yun personally investigated and found that the inside of this stone castle was divided into four stone chambers, and the ground of each place had a special passage made of pitch-black gas.

After careful analysis, Lu Yun found that through these four passages, he could reach another place far away. At the same time, under this passage, Lu Yun also collected the breath of many demon sharks, indicating that there were a large number of troops hoarded inside, and once something happened, those demon sharks would pour out from the passage here, facing the intruders head-on. As for the four passages, due to the maintenance of a large amount of pitch-black gas, they are very dense and extremely corrosive, and non-Black Sea masters cannot cross them.

Retracting the detection wave, Lu Yun glanced around, and said indifferently: "Sea Girl, are you sure to pass through the passage here and enter below?" ”

The sea lady rolled her eyes and said with a smile: "The master has come to test me again, so I won't tell you." ”

Lu Yun looked at her, saw that she looked proud, and a little naughty, and couldn't help scolding: "A little cleverness will be proud, and I will really discipline you more harshly in the future." ”

Seeing that Lu Yun was a little angry, the sea girl hurriedly coquettishly said: "Master, the sea girl will not dare in the future, don't be angry with me." ”

Lu Yun said with a straight face: "Then you answer me, are you sure to go on?" ”

The sea lady nodded hurriedly and said, "Yes, the sea girl has a seven-star dragon ball body protector and is not afraid of any poisonous gas." ”

Lu Yundao: "If you don't rely on this, can you still do it?" ”

The sea girl thought for a moment and said uncertainly: "If you don't do that, you can try to open that layer of poisonous gas and spread a defensive barrier outside your body, but then go in." ”

Lu Yun was expressionless and asked, "Is there anything else?" The ama shook her head and said, "It's gone." ”

Lu Yun glared at her and snorted, "And the most important point, you always forget." Before entering, you must test your defensive barrier to see if it can withstand the erosion of this poisonous gas. If you can, continue, and if you can't, you have to find another way to avoid getting into a desperate situation. ”

Hearing this, the sea lady smiled and flattered: "The master is so smart! ”

Seeing her coquettish expression, Lu Yun scolded with a smile: "Don't make sycophants, remember to study seriously in the future." The ama laughed coquettishly, and the voice should be yes.

Letting go of the ama, Lu Yun approached the passage in the center of the stone room, and after staring at it for a moment, he spoke: "Aenye, what do you say we should do now?" ”

The sea lady was a little puzzled, and Lu Yun's words were not easy to answer. However, since Lu Yun was standing next to the passage entrance, his question was obviously related to this passage entrance, so what did he want to express?

After thinking about it, the sea girl thought of a lot of questions, but she couldn't determine Lu Yun's true intentions, so she had to guess: "Master, do you want to seal these four exits so that those demon sharks can't come out?" ”

Lu Yun glanced at her and said with appreciation: "This time it's quite smart, but this gas is extremely corrosive, how can it be sealed?" ”

The ama shook her head and said, "This ama doesn't know. ”

Lu Yun didn't scold her, but smiled indifferently: "There are many things we don't know in the world, and we need to analyze and observe." As far as the situation is concerned, this gas has been around for thousands of years, and it is obviously impossible to destroy it immediately. In this way, we need to consider. Since it can't be destroyed, is there a way to change its nature and let it actively restrict the demon sharks inside so that they can't pass through. In that case, our goal will be accomplished. ”

The sea lady looked at the entrance of the passage and said thoughtfully, "Is this possible?" ”

Lu Yun shook his head and said, "I've tried, this doesn't work, but it doesn't mean that there is no way." ”

The ama asked, "Is there anything the master can do?" ”

Lu Yun thought for a moment and said softly: "You are still young now, some things can be easily understood, but some things cannot be understood yet." Right now, things here are a bit complicated for you, and the master doesn't force you, and directly tells you how to deal with it. First of all, we have to pass through this level of passage, and under this layer of poison gas, we will set up a new barrier. This barrier is very strict, not to hinder the entry of poison gas, but to prevent the return of poison gas. In this way, when the demon shark encounters it, it will be blocked by it. Secondly, we need to come back to complete this, but we must not destroy the enchantment we have set up, which needs to be considered before we do it. ”

The ama exclaimed softly, "It's complicated. ”

Lu Yun said: "Yes, many things in the world are very complicated. Okay, I'll take you down, and you can observe it yourself, it's better than saying it with your mouth. After speaking, a blue light flashed around him, and a powerful barrier separated the two of them, and then fell towards the entrance of the passage.

When crossing the passage, Lu Yun clearly realized that in the poisonous gas, thousands of microorganisms were frantically devouring the aura outside his body, moving closer to his body.

Lu Yun knew in his heart that the so-called defensive enchantment was actually a cultivator who manifested the aura contained in his body in a gaseous state or similar form to protect his body from harm. The usual virulence is composed of countless microorganisms, which show different characteristics and reflect different states due to different species, so as to distinguish the strength and weakness of the virulence.

After passing through the passage, Lu Yun and the sea girl came to another world, surrounded by ghostly lights, countless phosphorescences like ghost fires, giving people a strange feeling.

The sea lady was a little surprised, and said softly, "Master, it's so strange here." ”

Lu Yun probed the surrounding situation and replied: "It's nothing, this place is just a little more spacious, five miles away in the past, there is a long and narrow passage, hundreds of miles, which should be connected to another important location in the Black Sea." ”

The sea lady said: "Then should we go and take a look?" ”

Lu Yun said: "No need, let's seal this place first." After saying that, he took the ama to the four passages and began to act. This time, the seal set by Lu Yun was very peculiar, and its nature was completely different from the past. He adopted the "method of rebirth" he learned from the sea heart whirlpool, and combined with what he had learned, he laid out a transparent barrier in the form of a whirlpool. In this way, the barrier is extremely tough, and can block the passage of almost all sea beasts.

On the side, the sea girl looked a little dazed, she was in a young grade, obviously knew very little about the mystery of Lu Yun, and could only watch the excitement. But even if she watched the excitement, the ama saw something, but it made her even more confused.

Soon, Lu Yun completed the seal and said to the sea girl: "Let's go, let's go back from the other side." ”

The ama wondered, "The other side? Where? ”

Lu Yun smiled: "There are five stone castles in this stone, I guess it should be symmetrical from them." After saying that, the figure flickered, and in the blink of an eye, he came to the second stone castle on the right.

Looking at the four passages above, Lu Yun knew that he had not guessed wrong, so he didn't say a word, so he tried to seal this place again. Then he took the ama through the seal he had laid and entered it.

Looking around, the situation was exactly the same as what he had seen before, which made Lu Yunjian frown slightly, and said to himself: "With such a distribution, what is hidden in the stone castle in the middle?" ”

The sea lady said: "Let's go and see." ”

Lu Yun said with a smile: "It's not as simple as you think, when I passed below just now, I probed the situation of the middle stone fort and found that it was completely isolated from the other four forts, and I couldn't detect the slightest fluctuation." ”

The ama wondered, "So what? What does it mean? ”

Lu Yun said: "I don't know, I won't know until I enter, let's go." ”

When he came to the middle stone castle, Lu Yun did not enter immediately, he took the sea maiden to hide outside the stone castle, avoiding the sight of the surrounding demon sharks, but began to detect the stone castle. The appearance of the stone castle is not very impressive, but the four stone gates have an invisible enchantment seal, which is obviously different from the other four castles.

Lu Yun analyzed the nature of the enchantment, and the result he got surprised him, it turned out that this enchantment was extremely weird, it was actually composed of special gases emitted by the four stone castles, once it touched it, it would immediately attract the attention of the other four forts, and automatically issue a warning.

Knowing this, Lu Yun began to think. Among the five stone forts, only the stone fort where Hei Li was located did not move, in other words, once the Dao Four Forts were alarmed, he would only be alarmed. At that time, there was bound to be a conflict between the two sides, but Lu Yun didn't want to kill him at this time, and wanted to keep him here. This time, Lu Yun had to avoid him first and find an appropriate method.

Thinking of this, Lu Yun pulled his attention back to his eyes, thinking about why this stone castle had an enchantment, and what was hidden in it? For a moment, Lu Yun thought of a countermeasure, wanting to use the "space jumping" technique to pass through this stone gate.

Of course, there are risks, but Lu Yun has also thought about it, once he is alarmed, he can use the technique of space jumping to shuttle back and forth between the five stone castles, so that he will not be able to find his whereabouts.

With a decision, Lu Yun acted immediately, and everything went smoothly, and he easily entered it.

Looking around, Lu Yun's face changed slightly, this stone castle is quite weird, there is nothing abnormal on the outside, but the inside is extremely spacious, obviously the stone gate is not only a passage, but also a time and space.
