Following the two patriarchs and their confidants along the way, the residents around them gradually disappeared and came to a very desolate place. Then they entered a not-so-wide alley, which seemed so dark and quiet.

The two patriarchs stopped in front of a wall for a while, and Li Feng could feel that they were using investigative methods to investigate whether there were other idle people around. In addition to the two patriarchs, the surrounding confidants were also investigating differently. Among them were mechanical in technology, perception of magic, etc. After these people looked at each other and nodded in affirmation, they believed that there were no people around them to follow them.

Then he did not stop at the wall in front of him, but instead continued to walk forward. These alleys were a bit narrow, and the most appropriate way was to make three people walk side by side.

"Everyone must follow closely. This is a maze. The wrong route has the terrifying trap we set. If you mistakenly enter, even with the skills of several strong people, you may be at risk of serious injury. Others are even more inauspicious."

When moving forward, Bing Ling reminded him in front of him. The strong man in his mouth was the fifth-level vocational agency, while the others refer to the remaining fourth-level vocational agency. It is a kind reminder and a warning.

No one spoke, but continued to follow behind silently. Li Feng felt the elemental aura coming from around him. Bing Ling did not lie. Although the aura was not strong, it did hide a large amount of traps with the two attributes of water and ice.

The hidden method of this trap is very powerful, and it is probably a secret method passed down from their clan. It is even more concealed than ordinary elemental traps, and it is basically impossible to detect the hidden elemental aura.

Li Feng secretly glanced at the other great magicians around him, and saw that they were frowning slightly, as if they were worried about something. As Li Feng expected, they were also looking for the so-called trap like themselves. But they seemed to be unable to sense it, and only Li Feng could barely feel the existence of this trap when he had elemental affinity, and even the other great magicians could not detect it.

Therefore, these people frowned, wondering whether Bing Ling was deceiving her bluff or whether there were really traps to escape her eyes. The great magicians still believed in the latter. After all, such a large Shuihan Island must still be defensive. However, for the magic traps that they could not see, they felt that they were powerless and that their strength was not enough to underestimate everything.

It is really a trap that even a great magician cannot feel. So for those who break in rashly without knowing the right path, it is basically the same as a dead end. Li Feng sighed in his heart that the foundation for thousands of years is indeed not a joke. Shuihan Island has amazing technology in many places.

After passing the winding road like a maze, Bing Ling and Shui Ling stayed in front of the same wall again. There were roads in front and behind, and the monotonous walls in this maze were basically not noticed.

Li Feng closed his eyes and felt that the two patriarchs did not make the same deceptive actions as before, because the wall in front of him was indeed stained with an illusion. Under the influence of the illusion, the area in front of him seemed like other walls, which was a very ordinary wall in a maze.

Shui Ling waved his hand, and a spell of dispersing spelled on the wall. As the dispersing took effect, the illusion slowly disappeared, revealing its original appearance. A huge round steel door appeared in front of him, and the entire door gave people a feeling of thick and majesty.

After a little experience, I used a certain material that can be called one of the hardest alloys. It is said that the forging process is quite complicated and there are also a large number of precious metals in it. Li Feng has only seen this alloy in the book, saying that this alloy is used in the most important core areas of some cities.

The material is hard and can be compared with clay bombs commonly used by hunters. Assuming the thickness of the gate is five centimeters, then the clay bomb is covered with the entire gate, and the detonation is at most a little black, and the entire gate is still motionless. If you use the most commonly used unstable element crystals of Li Feng, then stack fifty kilograms in front of the door, and the distance generated by the explosion can only be broken into pieces. The unstable element crystals of 50 kilograms, Li Feng once faced a monster with super strong strength from the foreign land in the task of following the shadows, and was blown to pieces by this amount of elemental crystals.

The thickness of the door in front of me is definitely more than five centimeters. All objects are ultimately composed of elements, and mages such as Li Feng can measure their depth based on their elements. The harder and thicker the substance can be measured, the less the maximum thickness, and the more common the substances with lower strength, the higher the maximum thickness.

When detecting underground, Li Feng could sense the situation about thirty or fifty meters underground, such as whether there is any substance buried, and it can be found after intentional exploration. For ordinary steel, it can also be explored nearly ten meters. If you dive into some places, you can vaguely feel the internal situation through elemental detection. Whether to dive into or explode is helpful.

As for this super-strong alloy, Li Feng could barely explore it by 20 cm, and no matter how deep it was, he could not sense anything. The only thing that can be confirmed was that the thickness of this gate was definitely more than 20 cm. How terrifying is this? It may not be able to open smoothly after a long time with a magic crystal cannon.

"This is the only forbidden area on our Shuihan Island. Not to mention foreigners, our own people cannot come in. Only the patriarchs and ten confidants of all generations can enter. There is a reason for this, so that everyone can enter this forbidden area. Please keep it confidential. The important secrets about our Shuihan Island and the personal contracts of everyone here. Thank you."

Shui Ling explained to everyone again that the people around him remained silent, while some nodded slightly.

Then Shui Ling and Bing Ling took out an item from their arms, combined the two items together, and spliced ​​them into a whole key.

Clang...

Insert the key into the thick door, and the sound of unlocking comes from the turning door.

The closest confidants around him signaled everyone to retreat, and everyone took a few steps back. The door opened and turned 180 degrees to fit on the wall next to him. At this moment, Li Feng also saw that the door was really thick, about 30 cm. With this thickness and this narrow position, people could break through the door casually, which was not something that could be broken in a short time.

Standing in front of the door, a biting cold air came from inside, penetrated into everyone's bone marrow. Even though everyone present was very resistant to the low temperature, they still couldn't help but tremble in the face of this cold air. Except for the two patriarchs, even the confidants couldn't help trembling.

Then the two clan leaders entered first, and everyone entered one after another, entering the forbidden area.
