Xia Li took out the password suitcase her father left for her.
The entire suitcase is black and made of metal. The seams are tight and only a combination lock can be unlocked.
Xia Li held the box in his hand and looked around, frowning unconsciously.
I have some doubts in my heart, is this really what those people are looking for?
The combination lock sounds very high-end, but in fact it is not difficult to solve.
Even if the combination lock on the box fits perfectly with the box itself, there is no way to violently remove it by tightening the screws.
Xia Li wasn't sure what those people were looking for, so he didn't think too much about it.
He took out a flashlight from the space and pointed it at the gap in the code disk.
Sure enough, a small groove was found in the gap of the code disk. Although it was not very obvious, it did exist.
The numbers corresponding to the three code disks are nine hundred and twenty six.
Xia Li pulled the lock button, but it didn't open.
Turn all the numbers on the digital dial one digit to the right and pull the unlock button again, but it still doesn't open.
After trying this for five times in a cycle, when Xia Li pulled the button open again, the button was pulled open.
Xia Li:......
I feel more and more unreliable. Is this lock too simple?
Because it was too simple, Xia Li's defensive mentality instantly rose to a higher level.
Being behind in science and technology does not mean that China is falling behind in the inheritance of its ancestors.
What if the lock outside is just a cover-up, and as soon as the box is opened, a bunch of arrows pop out and head straight for the front door?
Xia Li was worried, stood up, walked to the side of the box, stepped back a little, and slowly opened the box with a small wooden stick.
"Crack!" The box was opened like a clam shell, and the top lid hit the table, revealing a stack of white A4 paper inside.
However, nothing happened.
Xia Li:...?
For a moment, she didn't know whether she was looking in the wrong direction, or the person who hid the thing was too perfunctory, or the current level of password locks was just like this, it was all the fault of later generations being too developed.
When Xia Li saw this scene, his first reaction was that this pile of paper was probably poisonous, and whoever touched it would die.
Otherwise, is this anti-theft system a bit too "low-key, simple, and useless"?
But after thinking about it, I realized that she was overthinking it. This possibility was extremely small. Normal people would not smear poison on paper to prevent others from seeing it, instead of tampering with the anti-theft system.
Even if you poison one person to death, can't others still wear gloves and continue to watch?
Silently lighting a candle for himself who had been frightened for a long time, Xia Li picked up the pile of paper from the box and read it carefully.
This stack of paper is a sketch, with various mechanical structures and assembly methods drawn on it.
Whether it is in terms of material notes or how to fit them together, they are all clearly drawn and detailed.
After Xia Li read it once, he could basically confirm that this was a document for manufacturing close-range defense cannons.
Although it is only a semi-finished product, it has already begun to show its scale.
Xia Li remembered that the close-in defense gun mount was the last line of defense on a warship, used to intercept incoming anti-ship missiles.
Historically, the world's first short-range defense weapon system was the AK-630 six-barreled 30mm gun produced by Mao Ziguo in 1970.
China started the project design in 1985, and it was only applied to battleships in 1990.
If this information really existed in history, the time for China to create close-in defense artillery would never have been delayed so late.
Xia Li looked a little ugly when he saw this information.
So this is what her dad always wanted to protect?
If she traveled through real history, then why did China have this close-in defense artillery design that had begun to take shape, but the close-in defense artillery it produced was only used in the 1990s?
It’s easy to imagine why.
Thinking of her parents, Xia Li's eyes felt a little sore, and she didn't dare to think about it at all.
He pursed his lips, put the entire document on the table twice, rolled it into a pile, and put it into the password box again.
The moment his hand touched the bottom of the box, Xia Li's hand suddenly stopped.
