After walking into the darkness, Zhao Xu took off and flew in this dark cave, relying on his constant dark vision, he directly stimulated and did not need to illuminate, and the whole process was constantly advancing rapidly.

At this time, he was blessed with the four-ring "High Atmospheric Wings" spell on his body, and the mobility of his whole body reached a perfect state, like a flexible bee, directly doing various extreme actions in this winding cave tunnel.

It wasn't until he galloped for almost 15 minutes and passed by no less than five forks that Zhao Xu slowed down and re-looked at the huge square he had just broken into.

The tandols are epiphytic to the ceiling, emitting a faint green fluorescence.

No matter how you look at it, this place looks like a playground for large-sized undead creatures like the giant insect Nightshadow.

After Zhao Xu wandered around, he stopped.

This place, connected by no less than twenty or thirty forks, belongs to the kind of place that is easy to attack and uncomfortable, but it is also suitable for him to catch a few intelligent undead creatures to explore.

The current Zhao Xu is waiting for these undead creatures who are not very capable of causing harm to him.

However, he also secretly sighed that the space under the cave was probably far beyond his imagination, and he had just galloped like this, although he was picking up the path and trying to avoid the main road, but he still didn't meet a few players.

Zhao Xu did not stop and continued to carry out his intelligence work.

If you want to find out if there is a gold mine or treasure box buried in the ground of your home, you can also use a metal detector.

And Arthury, the one who can take care of everything, that is "spell".

"Treasure Perception."

An hour-level three-ring spell was released, and in an instant, Zhao Xu's whole body was surrounded by colorful metallic light, as if a mist emitting a glimmer was spinning around him.

Immediately afterwards, these mist took the initiative to burrow into Zhao Xu's nose, making him can't help but sneeze.

The next moment, the breath of the treasure in the air instantly passed into Zhao Xu's nasal cavity-

During the duration of the spell, gold, silver, copper, platinum, and gems within 6 meters will be perceived by Zhao Xu to exist in the direction, and when they are close to within 2 meters, they can judge the exact location.

This ensured that Zhao Xu would still be able to sense the location of some obvious dragon crystals even if he was careless, the only problem was that if the thickness of the rock was more than 30 centimeters, or the lead sheet, or even the soil was more than 1 meter deep, it would be able to block the effect of this spell.

However, Zhao Xu didn't stop there, he directly released a spell that only existed in the "City Domain", a spell that was not on the list of priest magic and mage arcane-

The Fourth Ring "Awakening City"!

10 minutes of spell casting time, but in exchange for knowledge of a city, as if you have become one of the community, know the population, race, proportion, highest level of occupation, type of power center, and the most powerful item in the city.

If Zhao Xu had mastered this spell in the Eternal Sleep Land of the Death Half-Plane, he would have been able to know the details of that undead city in an instant.

However, at this moment, Zhao Xu discovered this spell and found nothing.

It's not a city!

That is, there is no artificial center of power, these undead creatures are just unconsciously gathered!

Faced with this, Zhao Xu was not depressed, because this judgment had told him enough.

Zhao Xu, who took a deep breath, continued to cast the spell "Leyline Exploration" that he had used.

At one point he had returned to the vicinity of the ancient Molin Stone and used this spell to release a green aura, when a map of the nearby terrain appeared directly in his mind, showing cities, villages, and famous ruins.

It's just that now Zhao Xu is still in chaos in his brain, and his aura has been forced back.

"Legends!" - Get legendary deeds about an important person, place, or thing.

"Ask Nature!" - Become a part of the natural world and know the surrounding environment, such as landforms, plants, mineral deposits, water bodies, residents, etc.

In an instant, after these two powerful spells were used, Zhao Xu couldn't help but breathe a little tighter.

Nothing!

In particular, he asked about the spell that could detect the ore vein, but he didn't give a hint, as if this void was suppressed by a mysterious force.

Moreover, it is too strange that the undead creatures that were supposed to arrive could not even see a single figure.

Zhao Xu continued to turn around and look at the situation around him, and he couldn't grasp the clue.

He was even looking at the lines on the strokes that looked like they were cut by a blade, as if he wanted to see through life and death.

Immediately afterwards, Zhao Xu brushed up on his knowledge and skills, and reactivated the professional ability "Learning" of using the level 1 monk priest - learning about local celebrities, legendary items, noteworthy places, etc.

But it's still like a bamboo basket to draw water.

Zhao Xu looked at his knowledge level of more than 80 levels and realized that this was not so simple.

"Young man, don't waste your efforts." Suddenly, an incomparably old voice came from behind.

Zhao Xu turned around in surprise, obviously he had a global vision, but he waited until this moment to find that a mysterious old man was standing behind him, and at the same time, the other party did not have any invisible traces.

Let his "flash explosion" and "see through the invisible" spells be forced back.

The old man in front of him was clumsy, and his head was densely covered with gray hair, even hanging down to his chest, revealing only those bright eyes.

The old man still had a wooden sword in his hand that looked a little broken.

Arthur doesn't have a sword without a sword, grass, trees, bamboo and stone can be a sword, and a wooden sword without enchantment is born to beat a magic sword.

Is there a player who is so old like a beggar?

Or is it undead camouflage?

In an instant, Zhao Xu's eyes silently cast the "Detect Immortality" spell, sweeping over the old man in front of him, but in exchange for a confusion - he was blocked, or the other party was the same as him.

"Funny little ghost, actually meeting is detection." The old man shook his head and smiled.

"When you go out, be cautious, and I have to judge whether you are a lich in disguise, old man." Zhao Xu explained.

Everyone has heard the story of the farmer and the snake, and Zhao Xu also knows that these evil undead creatures will also use the goodness of human nature to attack.

When the old man heard this, he immediately burst out laughing, which also made Zhao Xu see that even if he was old, his teeth were still white, which was in stark contrast to his sloppy body.

"Aren't you surprised that you can't see half an undead creature wandering around in this big hall?"

Saying that, the old man's gaze stared at Zhao Xu who deliberately attracted the undead, and only hung a simple cloth bag containing dragon crystals around his waist, "Especially, you also appeared here with this kind of divine object that attracts the undead." ”

Hearing this, Zhao Xu turned pale, and the "Rapid Burst" in his hand, or the "Elastic Magic Ball", "Force Wall Technique" and the like shot out at any time.

The old man in front of him was exuding an aura that made him feel extremely dangerous.

"Who the hell are you?" Zhao Xu continued to ask.

"It's the star cloak of physical immunity, Antinoia's girl?"

At this time, the old man smiled frustratedly, "But what does this matter to me, what is in front of you is a lost person." ”

"Or, you can call me another name—Ying Undefeated, one of the founders of the Nine Swords System."
