Driven out of my home in the apocalypse, I built a fortress in return.

Chapter 285 Transmitting Sound Across Thousands of Miles! Ultrasonic Waves!

"And the reservoirs, they're so many times larger now, we'll have to build several more..."

Previously, Longcheng was not very large, so building one or two reservoirs would suffice.

There is a small reservoir in the residential area that supplies water to hundreds of residents;

Another large reservoir is located in the planting area, which supplies water to both the planting and aquaculture areas.

The reservoir in the residential area remains unchanged.

However, if Xiao Yu wants to expand the planting and breeding industries, he can build several more large reservoirs.

"If all these farmlands are planted with crops, the planting area will need to be divided into two zones!" With a thought, Xiao Yu divided the entire planting area into two regions.

The current shell area of ​​the earth dragon turtle is only about 20 million square meters.

The area of ​​cultivated land and aquaculture areas alone has reached more than ten million square meters!

The partitioning method is very simple.

The eastern section is located on the left side of Longcheng Avenue, where corn, tomatoes, and cabbages are grown.

The western section, located on the right-hand side facing the outer city, is mainly planted with Jerusalem artichokes.

This is also to prevent Jerusalem artichokes from spreading and causing harm to the entire planting area in the future.

There was a ten-meter-wide road blocking the way, and no matter how domineering Jerusalem artichoke was, it couldn't get through at all.

"As for the outer city... everything else will remain the same for now, but let's add three hundred more forges!"

With several hundred more blacksmith apprentices added to the forging area, naturally more forging rooms need to be added.

As for the commercial street, it remains basically unchanged.

Just then, a strong wind swept through, sending sand and stones flying everywhere. Xiao Yu frowned slightly.

"Dragon City has been renovated; we must restore the crystal shield immediately." He flashed again, appearing in mid-air, and together with the crystal beast, enveloped the entire Dragon City once more.

At the same time, dozens of crystal pillars, each several meters thick, were built to support the light shield.

Even if the crystal mirror is broken, as long as these crystal pillars remain.

Xiao Yu and the Crystal Beast could teleport there instantly and restore the entire light shield in a very short time.

In addition, leave round holes with a diameter of about two meters on all four sides.

To allow for air circulation, a flock of pheasants can freely come and go.

"Is it already evening?" After drastically transforming Dragon City, Xiao Yu looked up at the sky and found that the sun had set, with colorful clouds rising on the horizon, which was quite beautiful.

"But... it's finally all done!"

With everything finished, he surveyed the vast city lord's mansion, feeling completely satisfied.

"Wow~"

Just then, a piercing cry of a child rang out.

And there's more than one place.

Before Xiao Yu could even wipe the sweat from his forehead, he frowned.

He knew that the child was frightened by the noise made by the earth dragon turtle.

Thinking of this, he immediately transmitted his voice, "Chenlong, Tienan, weren't you ordered to maintain order? Quickly notify everyone that the Dragon City renovation is complete, and reassure everyone!"

"Lord City Lord!"

Upon receiving the order, Chenlong and his companion rushed over immediately, but they said with a wry smile, "Lord City Lord! The city walls and the ground where everyone is are cracking rapidly. Only a few people are still gathered together, and most people have been separated by the cracks. We need to gather the lost brothers first before we can maintain order."

"Forehead..."

Hearing this, Xiao Yu was speechless.

But then I understood.

After all, there aren't many people in Dragon City who can fly.

Not to mention, when the Earth Dragon Turtle evolves, it's like the sky is falling and the earth is cracking, as if the end of the world has arrived.

Even a seventh-tier peak expert like Niu Dali was so frightened that his face turned pale.

Other sixth and seventh-tier experts, even if they could fly, were in extremely poor condition and dared not fly recklessly.

Just now, after the earth dragon turtle grew to its size, it instantly tore the earth apart, forcing most people to scatter.

“Before, the Earth Dragon Turtle wasn’t too big. If we shouted from the east of the city to the west, everyone on the west side could hear us. But now… even if we shout ourselves hoarse, the people on the other side can’t hear us!” Tie Nan said with a wry smile, his face full of helplessness.

"That is indeed a problem!"

Hearing Tie Nan's words, Xiao Yu shook his head with amusement.

Now, the earth dragon turtle has become too big.

Interaction and communication between the various teams have also become very difficult.

Once the Earth Dragon Turtle had finished evolving, Chenlong and the others busied themselves gathering their forces.

Therefore, it was impossible to immediately appease the residents, leaving them in a state of constant fear.

"If only we could invent a walkie-talkie, but unfortunately, the conditions don't allow it!" Thinking of the difficulties they might face later, Xiao Yu couldn't help but frown.

Effective communication between teams is a crucial part of defense.

If communication is not timely.

If the enemy attacks the east of the city, the west of the city will be completely unaware, resulting in delayed rescue efforts.

This would give the enemy the opportunity to defeat them one by one.

"In any case, this hidden danger is indeed very serious! It must be resolved as soon as possible!" Xiao Yu flashed back to the city lord's mansion in an instant, pondering countermeasures.

"Oh no, how could this happen?" At that moment, a cry of pain rang out.

His voice was mournful, filled with extreme sadness and grief.

"What's wrong? My little kitty?" Hearing the crying, Xiao Yu teleported to her side, reached out and held the white-furred catgirl's small hand, and asked gently, "Did someone bully you?"

"No, it's this little guy..." June sniffled and sobbed.

As she spoke, she showed Xiao Yu her palm.

"What is this?" Xiao Yu asked, puzzled.

There, on the white-haired catwoman's palm, lay a small insect.

It looks like a ladybug, with a few small green dots on its body.

If you look closely, you'll notice that these little dots seem to be glowing slightly.

"This is called a sound-transmitting bug!"

June wiped her nose and said sadly, "This was given to me by Wu Weier when we parted. She said that as long as we weren't too far apart, she would hear me if I talked to this little bug and then come to find us. But now..."

At this point, her eyes reddened again.

I finally reunited with my two best friends, but we had to part ways again.

I thought that with this communication insect, I could continue to contact them.

But now, for some reason, the little bug doesn't respond at all when I talk to it.

"There are actually creatures like that?" Upon hearing the catwoman's words, Xiao Yu instantly became interested.

He gently reached out and touched the ladybug's shell, a thought forming in his mind.

[Ding! 1 energy point consumed, successfully taming the Messenger Bug!]

[Ding! Copying the Sound Transmission Bug talent - Hundred-Mile Sound Transmission! Fusion in progress... Fusion complete.]

As the system notification sounded, the ladybug in June's palm instantly grew several times larger, reaching the size of a thumb. At the same time, the light spots on its body shone even brighter.

"Bai Li Chuan Yin?"

Upon hearing about this talent, Xiao Yu's eyes lit up.

This is a transmission from a hundred miles away.

This is not the kind of telepathic communication that's touted in martial arts novels.

It means exactly what it says: "a sound can travel a hundred miles!"

Within a radius of 100 miles, as long as a target is locked, you can transmit your voice to it.

This method of transmitting sound is somewhat similar to telepathy between immediate family members.

For example, if this little insect wants to transmit sound, it can only do so to its mother and its siblings. From a hundred miles away, the transmitting insects can sense what the transmitting insect is saying through the blood connection between relatives.

Then, copy it over exactly as it was.

However... with this method of sound transmission, the farther the distance, the longer the transmission time.

Originally, it would take at least a day for the offspring and the mother insect to communicate.

In addition, communication with the mother insect is the fastest and most accurate, while communication with sibling insects is less effective.

"Hahaha... It's like finding a needle in a haystack!" After digesting the innate ability of the sound-transmitting worm, Xiao Yu burst into laughter, his eyes filled with surprise.

The next second, he gave the order to evolve the system.

[Ding! 1 million energy points consumed! The Sound Transmission Bug has evolved to Tier 7! Its talent has advanced to "Ten Thousand Mile Sound Transmission"! New talent gained - Ultrasonic Wave.]

[Ding! Copying the Sound Transmission Bug's talents - 1. Long-distance sound transmission; 2. Ultrasonic waves! Fusion in progress... Fusion complete.]
