Sonar itself is a way for marine animals to explore the way in the deep sea.

For example, large whales such as sperm whales, they go deep into the sea to hunt, but there is no light in the deep sea and the sun cannot shine on the deep sea. The vision is completely useless. How can they hunt?

The answer is sonar, which emits ultrasound waves from their mouths to judge the size of prey and its movement trajectory. Do they look familiar?

Submarines imitate these marine creatures. In the dark deep sea, where nothing can be seen, submarines use sonar to judge the surrounding terrain and the size of the enemy.

If you want to avoid sonar detection, unless the giant beasts lie motionlessly in the deep sea like stones, even if they move, they can cause ultrasonic waves to fluctuate.

In this world, after the giant beasts appeared in the deep sea, it began to gather scientists around the world to develop more advanced sonars to judge and find giant beasts hiding in the deep sea.

Now that the research and development has been completed, it will be invested in the oceans spread throughout the earth, so that the giant beasts will be unable to hide.

With modern submarine technology, it is not realistic to kill a giant beast in the sea.

Although they cannot dive into the deep sea and kill them, before they dare to appear on land, humans can gather mechanized troops and ambush them in advance.

Hearing this good news, the representatives applauded, especially the great powers and coastal cities attacked by giant beasts, which were extremely miserable.

"Next, let's take a look at a edited video that only has three minutes, and then continue with the next topic meeting-"

On a projection, the wonderful fighting process of the evil spirit Avenger and the giant beast that day began to be played.

When the giant beast landed, there were already many spy satellites in the sky locking its figures, constantly shooting, and there were always some surveillance on the scene without fear of death or roadside surveillance.

The projection is completely divided into two sides, one is taken by satellites in the sky and the other is taken by ground.

Less than three minutes after the giant beast landed and the general situation was destroyed, a mecha giant suddenly appeared at the scene and saved a pair of human mother and son who were about to be trampled to death.

A giant mecha with a modern science fiction style, but what is puzzling is that the cracks in the joints of the other party are all experiencing flames, a giant robot combining magic and science fiction style.

As soon as the flame mecha appeared, the giant beasts could not be found in the east, west, south and north. Then a series of extremely beautiful actions threw the giant beasts into DJ Bay.

Finally, it was a beautiful backflip, interrupting the giant beast's feet, then latching its throat and twisting its neck, clean and neat, with beautiful and violent aesthetics.

"Three minutes, it ends in less than three minutes, and when you are bare-handed, do you know what this means?"

The introducer said excitedly, "Countless aircraft, tanks and warships, giant beasts that can only be killed by bombing wildly. A giant mecha can be solved in three minutes. No, if you have weapons, it may be faster. This shows that large mechas are the most effective way."

More importantly, save money—

"I suggest that we join hands with existing technologies to accelerate the development of giant mechas-" a middle-aged man with white hair stood up and said.

"We agree, and we are more willing to contribute the existing mecha technology-" A smiling fat Korean nationality stood up and agreed.

Others looked at him with contempt. Who doesn’t know what kind of mecha research in their country has not invested in it and has contributed technology?

So, based on many votes of approval, we unanimously decided on the research and development of large mechas. The next thing that was clamoring was who paid more money and who contributed more money, and constantly quarreling.

I guess it's impossible to divide it in a few days or nights. After all, no one is willing to contribute money and effort on their own, but others are lying down to receive the results.

Roger didn't know that his first appearance of the Evil Avenger directly promoted the birth of Gundam in this world. Unfortunately, after Gundam was born in this world, they realized that they were wrong. Only the Evil Avenger was the only one who quickly defeated the giant beast.

He was watching the TV news depressedly. On TV, Sydney was invaded by an even larger giant beast, and the planes on the news were bombing the monsters regardless of city casualties.

There is no way, I don’t know the time and space spells, so it’s hard to go over and help.

There are some magic runes of Kama Taj themselves, which does not mean that they will. When each rune is combined together, different spells will appear, just like program code.

I have never learned systematically, and I just want to infer complete spells in reverse based on a bunch of codes, and dream.

This made Roger feel extremely sad, and another opportunity to pretend to be arguing is lost in front of him-

At the same time, what made him feel sad was the soul of the giant beast, as if a newborn baby had no impurities and did not need to take a long time to digest like a human soul and directly integrate it.

"Oh, why don't the island country come to see a few giant beasts? Didn't monsters like to come to the island country to find Ultraman the most? I've been waiting for several days-"

In the middle, I couldn't help but go to the custom shop again, but I didn't see the kimono girl Yuriko that day. I asked the store manager and said that the other party was going back to study.

As for the contact information, their store has a confidentiality agreement and cannot be said.

I wanted to flirt with other girls, but I couldn't find that feeling, so I gave up.

[Major news from this station, jointly developed by many countries, the global marine sonar network has been put into use. Now the sea is like land, and all humans are monitored, and the giant beasts will have nowhere to hide—]

Next, the host excitedly introduced this Dahai Sonar Network, which is like Skynet.

According to the latitude of the earth, each area is placed, and the world uses ultrasound to detect the sea for 24 hours, leaving huge giant beasts without any escape.

The following report shows the location where all monsters are distributed, and the host directly introduces red dots.

[These are giant beasts that are not inferior to marine creatures based on super sonar. As we all know, giant beasts are very easy to identify in the deep sea because they are far superior to whales]

[At present, the global joint fleet has begun to gather to eliminate single monsters first, but I don’t know if they will rescue each other]

———

In Pearl Harbor, located in Hawaii, the Pacific, warships gathered, and the Mid-American army demonstrated the strength of a military power. After investing in global sonar, it can now take the initiative.

The only worry is what if the giant beasts can't defeat the deep sea? After all, there are only a relatively single weapon like torpedo in the sea, and the deeper the sea, the stronger the sea pressure.

The powerful deep-sea sea pressure is impossible to withstand, so if you want to attack them, you can only lead them to land or shallow sea areas before you can gather a large number of human mechanical troops to eliminate them.

In fact, humans have long detected a space-time wormhole in the sea, but there is no way to destroy it.

Fortunately, it seems that there are only giant beasts invading opposite the wormhole, and no alien fleets or the like come.

With the current human technology, it can still kill giant beasts. Instead, Roger's evil spirit Avenger appeared, leading humans to the giant mecha—
