"What is this?"

Fengyun saw a large amount of blue smoke coming out of the small wooden bottle that was thrown into the air by Miao, spreading out, like a big net covering it downward, his expression couldn't help but change, subconsciously like dodging.

"Benefactor, don't panic. It is harmless. ”

Miao Piao obviously noticed Fengyun's actions and cast a reassuring look at him.

Fengyun's body that had already begun to move stopped, but it wasn't because of what Miao Piao said, at least not entirely, he found that the blue smoke spread a very large area, and if he couldn't get out of the cave, he couldn't really avoid it.

Fengyun believed that there was a passage to the outside, otherwise Miao Piao and the other people of the Floating Water Tribe who had entered here would not be able to leave.

It's just that Miao Piao's movements are too fast, so fast that it's too late for him to find out the way out from him.

Soon, the blue smoke completely spread, occupying the entire cave, and the wind and clouds were also shrouded in it, and if you looked closely, you would find that the fog around him was a little thicker.

However, even though the blue mist around Fengyun's body was thicker than the other enemies, it was not able to actually touch his body.

Before the blue mist approached him, he unhurriedly activated the power of the totem and released it outside his body, forming a protective shield that protected him inside.

Although Miao Piao assured him that the blue mist would not cause any harm to him, for some reason, it was still reluctant to let it touch his body.

Urging the forces of nature to protect himself, although it will produce a certain amount of consumption, but he feels that it is worth it to let something unknown touch his body.

More importantly, with his current situation, the power of the totem will be released, as long as it does not take a long time, the burden on him will not be too big, and he can fully afford it.

"Benefactor, you ......"

Miao Piao noticed Fengyun's small movements, and his lips moved, but he didn't say anything after all.

The blue fog appears quickly, and it disappears not slowly.

It took less than ten minutes from the time it just came out of the bottle to the time it disappeared completely.

Fengyun did not remove the power of the totem that was released, and it took another moment.

In the process, Fengyun began to observe the situation in the cave, wanting to see if the appearance of the blue mist had any effect.

He was disappointed.

After looking around, he didn't find anything abnormal, but he still didn't give up looking, he didn't believe that Miao Piao was doing useless work.

When releasing Lan Yan, Fengyun once showed a look of regret on the face of its owner, and it was not easy to want.

In this case, Miao Piao should waste it casually, he must have used him for some purpose.

After observing for a while, there was still nothing to discover, Fengyun had to set his eyes on Miao Piao, although he seemed a little reluctant, but he also understood that this was the best choice for him to figure out the blue mist.

As the owner of the blue mist, he should know exactly what it can do, and staring at him, he can lead him to discover.

It turns out that the choice was correct.

Just when Fengyun cast his gaze on Miao Piao's body, he found that he was staring at something.

Fengyun immediately followed his gaze, and his instincts told him that the place Miao Piao was looking at was what he was looking for.

"Footprints?"

When Fengyun saw clearly what Miao Piao was looking at, she couldn't help but be stunned for a moment, but soon she showed a look of chagrin.

He should have thought of it a long time ago.

In fact, Miao Piao once gave him a hint. He said that he could know if there were outsiders in the space, and then he released the blue mist, and it was clear that there was a relationship between the two, but when it came to the end, he thought about it.

Fengyun stared at the footprints carefully, and soon found that he seemed to be familiar with them, but he couldn't remember them for a while, but after a while, he seemed to understand where his familiarity with them came from.

The soles, those shoe prints came from him, how could he not feel it.

However, not all of the footprints revealed by the blue light came from Fengyun, and some of them came from another person who entered the space, and she recorded all the footprints left by the people who entered the cave.

"Is this how you confirmed that you had entered this space?"

"How's it going? Not bad, right?"

Miao Piao looked at Fengyun and tilted his head, revealing a proud expression.

"It's really good, so that as long as someone has entered here, it will leave clear traces, as long as you look at it, you can see it at a glance?"

"That's true, but developer powder is very rare, and I use a little less. ”

Speaking of this, he suddenly sighed, and then said faintly: "But there is no use for the developer fans to stay." If you use it, you can use it. ”

Fengyun knew that Miao Piao thought of the tragedy of the destruction of the floating water tribe, but he couldn't say anything, if the persuasion was good, if it deepened his sadness, it would not be good.

Miao Piao behaved more freely, and soon shifted his attention from the tragedy of the floating water tribe to the blue mist IQ that Fengyun was interested in.

This time, Miao Piao made a detailed briefing, and through this story, Fengyun also had a further understanding of the blue fog, that is, the developer powder.

It is a bit of a way to show the footprints of people in a certain area, even if there are no traces left in the first place, which is very magical.

However, there are two sides to everything, and developer powder is no exception, and it also has disadvantages, such as the time limit for intruder detection.

After a long time, to be exact, more than a month, and then you want to use developer powder to reveal the traces left by the enemy, you can't do it.

In this regard, Miao Piao did not lower his evaluation of the developer powder, and it is quite good to be able to clearly show the footprints within a month.

Fengyun once wanted to ask Miao Piao for a developer powder formula, but he still held back.

He has seen the magic of developing powder, how can such a good thing be hated casually?

The footprints shown by the developer powder didn't last long, only lasted for about an hour, which may seem like a short time, but it was quite remarkable, and it was enough to provide a very great help.

I put the developer powder for a while, and I went around and around, and I paid attention to the missing treasure again.

Since no outsiders entered through the display of the developer powder, how did the treasure disappear, which made Fengyun's heart confused and even more curious.
