"Mr. Karl, what are you listening to?"

Little Lucy, who was collecting fluorescent moss, saw that Carl seemed to be listening to something, and couldn't help but stop the collection and asked in a low voice.

"Shh

Karl gestured quietly to little Lucy not to speak, and then listened more intently.

“...... Barceló, I know you're on your quest for the secret of the pirate king Roselik's treasure. What if I said I knew a clue about the treasure of the pirate king Roselik?"

"You know?"

"Barceló, although your Blood Skull Pirate Regiment is strong enough, and although there are many eyes and ears, it is only limited to the sea and various ports and docks! There is not much information about the land, about the nobility, and even about the church, you don't have much access to it!"

"Hmph, Sir Sterling, what do you want to say, if it's to show off your connections, you don't have to ......"

"No, no, no, dear Mr. Barceló, I don't have any sense of showing off, I just want to say that although you are powerful, well-informed, and well aware of what is happening on the sea, the land is a strange territory for you, and the fall of His Excellency the Pirate King Roselik was caused by the joint efforts of the lords and churches who rule this continent, and many of His Excellency Lotsellik's legacies have also fallen into the hands of many big people on the land, and some news can only be known by the nobles......"

“...... Think of how tempting it is to think of Mr. Barceló, the treasure of the Pirate King, the route of the New World, the legend of El Dorado, and the secret of His Excellency Roselik's growth from a small sailor to a legendary powerhouse......"

"You're trying to trade my secret clues about the Pirate King's treasure in exchange for my attack on your enemy, the Knight of Hanbania?"

"Yes, I can tell you the secret, but I must help me get rid of Hanbani Robec, and as a matter of sincerity, I can first tell you a small clue that the key to unlocking the Pirate King's treasure has fallen into your hands - did you find an obsidian gold coin that the Pirate King brought from the New World not long ago?"

"Obsidian coins?"

"Yes, it's the strange coins that the Pirate King brought back from El Dorado, one of which is a real obsidian gold coin, containing the Pirate King's treasure and the secret ...... of the New World's route."

Obsidian coins?

Hearing this, Karl couldn't help muttering, it can't be such a coincidence! The robbers in front of him seemed to be this Barsabo's men, and he also got a trophy from a robber that looked like a gold coin and a badge.

Thinking of this, Carl couldn't help but take out the trophy from his pocket, looked through it carefully several times, and rubbed it with his fingers a few times, and found that the gold coin like this badge was cold to the touch, not gold or jade, and it did look like it was carved from a piece of obsidian.

I went, it seems that I accidentally got into a terrible thing!

Carlton couldn't complain, feeling that after he crossed into this world, he suddenly became a mother system, and he could get into a lot of trouble by picking up one or two loot at random.

Thinking of this, Carl couldn't help but listen more attentively, trying to find out more secrets.

However, I don't know if it was out of caution or something else, the next conversation between Sir Sterling and Barcelona seemed to be blocked by some force, and he suddenly couldn't hear anything.

Carl couldn't help but lift his spirit, put all his energy into hearing, tried to use the mage's meditation skills, mobilized the power of the vegetative soul, and went all out to expand his perception of the wind.

Unconsciously, Karl's spiritual power spread out, following the wind flowing everywhere, like a huge spider web, widely spread in all directions, and all the movements within a radius of miles were all incorporated into the perception of mental power and hearing.

In an instant, countless messages were transmitted to Carl's mind and mind through the ubiquitous flowing wind.

This is a very peculiar experience, the combination of the ubiquitous wind and the spreading spiritual power, as if the hearing function of the ear has been expanded a thousand times, and countless sounds and movements are transmitted to his perception at the same time in an instant.

The sound of the air rubbing against the walls of the sewers, the activity of countless tiny bugs lurking in the dirt, the collision of dust and water droplets floating in the air...... Endless subtle sounds come together to create a colorful and lively world.

Carl suddenly discovered that people can see the world through "hearing", and the ubiquitous wind and water feed back countless information flows for him all the time, so that he can sketch a three-dimensional world in his perception without seeing it with his own eyes.

After the awakening of the dragon vein, Carl suddenly realized that his observation of the world did not rely on the traditional five senses. With the power of wind and water, his spiritual power directly increased his perception efficiency by ten million times.

This feeling, as if he suddenly grew a thousand eyes, a thousand noses, and a thousand ears, was able to receive more and more information in an instant, and in an indescribable angle, all the sensory organs were integrated into one, forming a new way of perceiving.

And just after Karl entered this new state of perception, the first thing he noticed was not the conversation between Sir Stirling and the pirate Barsabo, but a figure that had been following them closely and hiding in the shadows.

The faint fluorescence emitted by fluorescent moss only provides a faint amount of illumination, and darkness and shadows are everywhere in the sewers.

And a pitch-black figure is quietly hidden in this ubiquitous darkness, its shadow blends with the darkness of the sewer, its breath converges without a trace, and there is no sound in its actions.

Along the way, Carl and little Lucy both vaguely felt a feeling of being watched, but they searched several times but did not find any stalkers, and once thought it was their own delusion.

However, as Karl was engrossed in improving his hearing and wind perception, the figure that had been following them was finally revealed.

Although the stalker's methods were very skillful, and the aura was unflawed, the ubiquitous flow of wind, and the slight disturbance of the air brought by its movements, still revealed its presence.

Like the reflected waves of radar, the ubiquitous wind feeds back to Carl everything it touches, and naturally, it also allows Carl to see the tracker who has been behind them.

"I was able to discover my whereabouts, and it seems that the rumors of your defeat of Crassus are not all rumors!"

To Carl's surprise, the moment he noticed the stalker, the stalker also spotted his exposure from his undisguised expression, and took the initiative to show his figure.
