"well!"

Chiba Cheng sighed and pressed and poked in a slightly boring way. He didn't know which one he pressed. The machine suddenly shook imperceptibly, and then a slight "Buzz! Buzz!" came from under his feet.

The sound made Chiba Cheng startled, and then he saw a device the size of a soap box on the left hand side, which lit up.

"This...there's electricity???"

Chiba Makoto really didn't expect that the mecha that had been left for so long would still have electricity, and what was this device made of? It was so strong that it could continue to operate even if it was attacked by a nuclear bomb.

"What is this for?" Chiba Cheng leaned over and looked at the square box. The label on it was in English, which translated means 'echo'.

so...

"What do you mean?"

Chiba Cheng is a little unsure. What is the purpose of installing a device labeled "Echo" on it?

Radar?

But when it comes to radar, just label it as radar. Isn't it a bit abstract to use the word echo?

Any military equipment must be concise and clear, so that even in a tense battle, people can see the specific meaning at a glance. There must be no ambiguity, otherwise if the wrong button is pressed, it may be a disaster.

So this echo...

Chiba Cheng was racking his brains and thinking, when he suddenly felt the mecha under him shake a lot, interrupting Chiba Cheng's thinking, and then again, and the mecha shook even more.

, my ears also heard a loud "dong" sound coming from outside.

This sound reminded Chiba Makoto of the heavy footsteps and shaking he heard before he woke up. It was so weird.

"Monster?" Chiba Cheng didn't bother to study what this thing was for, and immediately walked towards the exit, wanting to see what kind of monster it was.

At the same time, in a remote, half-hidden underground base, the huge control room was full of people, with bright screens everywhere. An operator suddenly shouted loudly into the headset: "The sonar matrix is ​​receiving

Echo waves, contrasting, from Tango Wolf.”
