Chapter 520

Bang bang...

Continuous gunshots suddenly sounded in the laboratory. Without Tang Yu's instructions, the little raccoon had already controlled the drone to go to the direction of the gunshots.

At this moment, Achia was listening to Tang Yu telling her about the outside world.

"Ah! Really? A big bird emitting fire and lava fights with a mermaid. Is it the kind of mermaid whose lower body is a fish tail?"

Aqiya was very curious about what Tang Yu said.

"Yes, it's that kind of mermaid, and it's very powerful! His weapon is now in the hiding place."

Boom boom.....

Two explosions sounded...

The sound of gunfire disappeared instantly.

Seeing Tang Yu's gaze, the little raccoon nodded slightly.

They soon arrived at the submarine research area.

It's just that a password gate here blocked their way. Looking at the key card reader next to him, Tang Yu frowned slightly. They didn't have the key card here.

Seeing this, Jigula was ready to let Freddy violently break the door.

But at this moment, the originally closed metal door slowly slid to both sides after the key card reader made a clear 'beep' sound, revealing the road into the submarine research area.

this....

Tang Yu immediately understood what happened...

"Thank you, Agia!"

"You're welcome, just think of it as thanks for telling your story."

Behind Tang Yu, Jigula immediately took back Freddy and winked at Wang Bohu.

Jigula: It’s done! ! !

Wang Bohu also raised his eyebrows slightly.

Wang Bohu: Definitely! It doesn’t matter who takes action!

In this way, because of Achia's existence, Tang Yu and the others arrived outside a room without encountering any obstacles along the way.

[Deputy Chief Engineer Office]

This was the office of the mechanic's wife Eva, and it was also the area where the mechanic's safe was hidden.

The door opened automatically again, and Tang Yu walked into the room. It was still as chaotic as ever, with a trail of dried blood on the ground.

This should be the trace left when Eva, the mechanic's wife, was dragged away by the revolutionary army.

"Technician, we have arrived at your wife's office. Where is the safe?"

Following the view of a drone, the technician in the hiding place looked at the familiar office in the picture, and his eyes instantly became moist.

But he knew business was more important now.

He spoke immediately.

"Boss, it's on the right wall, right in the middle of the wall."

According to the technician's words, Tang Yu looked at the empty wall in front of him, confused.

At this moment, Tu Shanxi traded something to Tang Yu.

It turned out to be the mechanic's pair of glasses and a strange-looking silver coin.

"Boss, put on my pair of glasses..."

As the glasses were put on, in Tang Yu's field of vision, densely packed large and small gears appeared on the originally empty wall.

These gears mesh and rotate with great precision.

"Boss, look for a pair of gears of the same size that mesh and rotate. Then place the silver coin where the two gears mesh and press it hard."

In just a few seconds, Tang Yu found the pair of gears of the same size in the lower left corner of the wall. When the silver coin was placed in the middle of the gears and pressed hard, a miracle happened.

In the eyes of Little Raccoon and the others, they only saw Tang Yu coming to the lower left corner and pressing a coin against the wall. The coin seemed to melt and slowly sank into the wall.

Click, click, click...

As the coins disappeared, the sound of gears turning came from the room. As these sounds sounded, the wall retreated directly from the middle to both sides. A wall made entirely of mechanical gears appeared in front of everyone, and this wall The gear wall also gradually appears with a narrow passage in the middle.

"Boss, come in!

The safe is inside. "

The drone had already flown into the passage in advance, and sure enough, a mechanical safe appeared ten meters ahead, and the silver coin that had been stuck in the wall had already appeared above the safe.

At the technician's prompt, Tang Yu picked up the coin again and started twisting it at a specific location in the safe.

Until two minutes later, with a soft sound, the safe opened, revealing a folder inside.

"That's it. Here are the construction drawings of all the supporting facilities of the [Camer Bernards strategic multi-energy submarine]."

Tang Yu briefly looked through it and looked happy.

[Construction drawings of the submersible weapon vertical launch unit] [Construction drawings of the submersible torpedo silo] [Construction drawings of the ecological cabin]....

Tang Yu was extremely surprised to see more than a dozen rare drawings.

The folder was immediately traded back to the hideout via the flea market.

"Tu Shanxi, immediately start collecting construction materials for these drawings."

"Boss, there is a material warehouse in this area. Although it may have been looted by the revolutionary army at first, some things may be refreshed in it now. You can go and take a look."

The mechanic's words rang out in time.

Tang Yu was overjoyed.

Just as he was about to go to the warehouse, he suddenly saw something that seemed to be at the bottom of the safe.

What's this?

Tang Yu looked closer, and then his eyes flickered slightly.

"Tu Shanxi, give this photo to the technician!"

After saying that, he walked towards the warehouse.

In the hiding place, after hearing Tang Yu's words, the technician took the photo handed over by Tu Shanxi in a daze.

Of course, after seeing the content on the photo clearly, his body stiffened instantly.

"This... this... when was this put in?"

The technician's hands holding the photo began to tremble a little.

In the photo, he was still very young at that time sitting on the lawn, supporting his body with one hand and holding Eva who was laughing with the other hand. A black and white puppy was chasing butterflies behind them. Everything was so peaceful.

"Eva... Toronto"

His palm stroked the photo, and a tear flowed from his eye and dripped on the photo.

Tang Yu left the office and separated from Wang Bohu and the other two, and each began to collect supplies.

And Tang Yu also began to put all the mechanical equipment he could see into the backpack space. During this process, Tang Yu paid attention to Aqia's reaction and did not stop as expected.

When the collection of the submarine area was completed, Tang Yu looked at other areas. He first entered the mobile fortress and capsule space area. Just like entering the submarine area, all the password doors would automatically open when Tang Yu passed by.

The actions of several people were very fast, and everyone in the hiding place also took action and began to fully receive all kinds of materials traded by Tang Yu and his friends.

When the other three areas were all looted.

Tang Yu looked at the last [Artificial Intelligence] R&D area.

He paused for a moment, and after thinking for a while, he asked softly: "Aqiya, what about you? Do you want to leave here with me and settle down in my hiding place?"
