Chapter 1665

This is the same as the medium of sound propagation. The speed of sound propagation in air, liquid, and solid is different. Among them, solid propagation is the fastest and the most clear. This is Because the vibration of the sound is more obvious, the sound can travel so fast and so clearly.

However, air and liquid are not as good as solids. The vibration of sound dissipates more quickly in air and liquid, and the sound cannot be perfectly preserved, so it dissipates faster. The vibration of sound disappears, and naturally there is no sound. the existence of sound.

And Yi Xiaofan's perception is also the same reason, it is the most effective transmission in the pure air, there is not much hindrance at all, so it can go from here to there in a short period of time, Covers a huge area.

However, if the perception is released in the depths of the seabed, where there is liquid everywhere, there will be problems with this kind of transmission and coverage. After all, sea water is also a hindrance, which will prevent the spread of perception, so compared to Spreading in pure air and in sea water, Yi Xiaofan's powerful perception will also be hindered and weakened to a certain extent.

Then there is solid. Compared with air and liquid, solid is the first element that hinders the spread of perception. The material of this thing is more complicated, and it also hinders the spread of perception the most. Therefore, Yi Xiaofan is in a place full of walls blocking Unleash the perception, but still can't detect too many things successfully, this is the result of the weakened perception.

in the depths of the ocean,

Yi Xiaofan's perception can cover a range up to 8,000 meters in diameter. To be honest, this range is absolutely huge. After all, it is 8,000 meters, not 80 meters, 800 meters, or 8,000 meters. Inside, even the slightest clue may affect Yi Xiaofan's senses.

Therefore, in the depths of the sea, as long as he and Li Yan'er cooperate with each other, they can easily cover the entire depths of the sea within the range of their senses. The entrance to the target secret realm.

As he was moving forward, Yi Xiaofan who was inside the bubble suddenly frowned, and he quickly raised his hand to signal: "Yan'er, wait a minute, there is something wrong here."

After hearing the order, Li Yaner quickly stopped her air bubble sailing, and just stood still in the depths of the seabed. Yi Xiaofan's words not only attracted the attention of Li Yaner, but also Tang Jingya, Yang Yinger and others behind her. Li Goudan all focused on Yi Xiaofan, waiting for his next words.

Yi Xiaofan stood up straight, slowly turned the angle of his body, and then looked towards that place, and the rest of the people did the same, all turned their gazes towards the direction Yi Xiaofan was looking at, trying to get out of it. find something.

Everyone's eyes are like a scanner, constantly spreading in the depths of the sea, but, except for Yi Xiaofan and Li Yan'er, the rest, including Li Goudan, can't see their eyes so well. far distance.

While watching, suddenly at the end of Yi Xiaofan's field of vision, a black shadow appeared, it was huge, almost over a hundred meters long, and this

Dao Heiying is more than a thousand meters away from where Yi Xiaofan and the others are now.

"What did you see Xiaofan?" Yang Yinger asked from the side, she was always paying attention to the subtle changes in Yi Xiaofan's expression, just now, she noticed the change of Yi Xiaofan's face, so at this moment Open your mouth and ask.

Yi Xiaofan waved his hand and looked away: "If I'm not wrong, the target we are looking for should be over there, but" Yi Xiaofan's tone paused for a while, he didn't know Do you want to continue talking?

"But what?" Tang Jingya asked, she didn't know, what else would make this man frown and say it's just, isn't there some particularly powerful monster in front of him?

Yi Xiaofan looked around at the people present, and then said lightly: "It's just that there is a big guy waiting for us a thousand meters ahead. If we want to go to the entrance of the secret realm, we will definitely be seen by that big guy." ,
