Frontier Island, become an island guard after being discharged from the army!

I saw a small probe appeared together.

This is the ultrasonic detector that the system rewarded when it rescued the mother whale.

Ultrasound is not only emitted by dolphins.

And some marine life will also have it.

Whales also emit ultrasound every time they communicate with other whales.

Lin Tian was still thinking before that the system rewarded this ultrasonic instrument for its usefulness.

But look now.

TMD

It is very useful!

This thing can not only check the movements of dolphins.

And it can also capture the sound waves of intelligent creatures such as whales.

In this way, Lin Tian can even easily meet his "neighbors".

play.

And with this thing, Lin Tian can also find the whale mother, so that he can also see the migration picture smoothly.

This is simply, oh Sidisi open the door for Makabaka, Makabaka is home!

Take out the instrument.

Lin Tian could sense that this instrument, if placed in the whole world, would be like a treasure.

Moreover, this kind of instrument is difficult to invent, if it is exposed to the public's view.

It will definitely be noticed.

Therefore, Lin Tian does not intend to expose this ultrasonic instrument.

Look at the instrument.

Lin Tian was a little surprised.

This instrument is not big, very small.

It's like a tablet.

And there is an antenna on it, and there is something like a radar on the display.

This thing seems to be able to receive ultrasound.

And brain waves.

Lin Tian was dumbfounded.

Is this thing so crude?

It's really unpretentious.

But Lin Tian is very satisfied with this thing.

At least it is small and easy to carry.

Most importantly, it is easy to operate and easy to understand!

Lin Tian looked at the radar range.

Sure enough, there were four red dots around him.

These four are the little shark and the little sea eagle, Tuanzi and himself.

Shown above are brain waves, fluctuations.

And there is no ultrasonic wave on it.

It is very difficult for human beings to have ultrasonic waves, and they must reach that range.

For example, some singers may reach that critical point, but that must have a strong lung voice ability.

Naturally, the little idiot, Little Shark, would not have such a thing.

But the group may have a chance.

After all, tuanzi can be regarded as intelligent creatures.

Lin Tian looked at the detection on the instrument. …

Almost all brain waves, but, fortunately, they are normal.

Lin Tian played with the things in his hand.

Then put it on the table.

I don't need this thing now.

Use it later when you want to find the mother whale.

Lin Tian then took out the live broadcast drone again.

This thing is rewarded twice by the system.

The picture quality was not so good before.

Now rewarded with another one.

Lin Tian looked at the drone.

His first impression was that it was huge.

Twice as big as the previous one.

Moreover, the propeller of the drone was replaced with an iron sheet.

The overall body is black.

There is a display screen on it, similar to a submarine.

"The second-generation drone can last for five days, supports 9m Blu-ray live broadcast, supports noise-free flight, and can withstand nine-level winds!"

"There is a super signal inside, you can use the signal anywhere!"

System sound came.

Lin Tian swallowed.

He has been through storms.

The nine-level gust can blow trees, but this drone is indifferent.

Just outrageous!

However, Lin Tian was very happy to have this ultra-clear live broadcast.

I also have a monitor.

At that time, if you have difficulties, or say something else, you can also ask netizens for help.

But the only thing missing is that Lin Tian can no longer communicate with netizens.

The drone is flying in the sky, and he can't see the barrage!

"If there is a wireless headset, it would be great if you can read the effective barrage by yourself."

Lin Tian sighed.

system:"????"

Chapter 74 classic forever

Lin Tian put the drone on the table.

Tomorrow, he plans to use this drone to live broadcast, and he will definitely be able to surprise netizens.

The drones rewarded by the system all have an autonomous follow system.

So there is no need for Lin Tian to operate with the remote control.

Just turn it on.

"Good guy, the master has turned magic again!"

Watching Lin Tian take out two things out of thin air.

The little shark's eyes were straight.

Wouldn't it be great if the master could conjure up a beautiful female shark? ?

The little shark thought in his heart, and the saliva almost flowed out of his mouth.

Lin Tian frowned slightly when he saw the silly look on the little shark's face.

It's not menopause yet, the little shark has Alzheimer's?

Sure enough, it's not good to be too smart, it will be backlashed.

For a moment, Lin Tian showed some pity and pity.

Little Shark: "!!!!"

Master, what kind of look is this!Seems like a fool again!

"Humph!"

He yelled twice in dissatisfaction.

The baby shark plopped into the pool.

He is already missing Bai Xue now.

Wait for Bai Xue to come and bring back the female shark, then he will have a girlfriend!

At that time, the status of the family will rise in a straight line!

Lin Tian watched the little shark jump into the pool, but he didn't look at this guy again.

Instead, lie directly on the bed and go straight to sleep.

soon.

Twelve in the morning.

Lin Tian stood on the watchtower on time.

He looked at the calm radar and felt very comfortable.

He would rather never have any suspicious blips on this radar.

In this way, no fishing boats will be killed, or animals will be killed.

Tonight, there is no wind.

very warm.

Lin Tian looked at the stars in the sky.

Big and bright.

The sea is not just side by side with the sky.

Also side by side with the night sky.

Standing on the watchtower, Lin Tian seemed to be able to touch the stars in the night sky as soon as he stretched out his hand.

Those stars are very big, like shining gems one by one.

Lin Tian watched for three hours unknowingly.

After confirming that there was no problem, he turned off the radar and went back to sleep.

The next morning.

The sky is bright.

Lin Tianba sent back the sea level data detected recently to the base.
