"Newster College is mainly based on biotechnology, while my college, Blufowley College, is mainly based on mechanical technology, mainly to restore those science and technology before the war, and we have now restored some of the remaining historical records of the Second World War technology and the technology after it, including some military weapons. However, there are also some technically demanding requirements that cannot be fully restored even now. Xu Yiyi sighed a little, "The technology of that era is even much stronger than our current technology......"

"Huh? Has your technology collapsed to that extent? You can't even restore the technology of World War II? Dai Huadong was stunned for a moment, "How long has your solar system war been since World War II?" ”

"It's probably only about one or two hundred years."

"Maybe it's special in your world, right? Although our world has experienced two world wars, it is not yet capable of waging a war in the solar system. Dai Huadong said, "But what is in this box?" ”

"I don't know, there is only a number on it, and according to the number, it is military equipment from the World War II period restored by the military industry." Xu Yiyi looked at the string of capital letters and said.

"You guys from World War II?" Dai Huadong's eyes revealed a hint of excitement, something that could not be restored by a civilization that could have space folding technology, and it was only a hundred years away from them, how high was the technical content?

"Right? However, looking at the sign above, it is a defective product that has not been completely restored. Xu Yiyi touched the box.

It turned out to be just a defective product...... However, after dismantling, you can still get some of the technology, and that's enough. Dai Huadong nodded and said, "Then how do you open this?" ”

Xu Yiyi thought for a while, straightened the box, and then cut it from a 45-degree angle with a hand knife, and then a blue light screen appeared on the surface of the box.

"Then enter your password." Xu Yiyi said, and then turned the side with the light screen to Dai Huadong, "You can enter the password." ”

“……”

Suddenly cold......

"Do I still have a password to go here?" Dai Huadong wants to lift the table, isn't it true that the protagonist in the fantasy novel can use it immediately when he grabs someone else's ring? Or you can use it immediately after erasing some marks on it, how can there be such a thing as a password!

Xu Yiyi said as a matter of course: "This is to prevent the students from tampering with the experimental objects and causing unnecessary harm." ”

"......" Dai Huadong silently looked at the icon of the Sogou input method in the corner of the keyboard on the light screen, "How many digits is your password?" ”

"Not sure."

"Is your password still text entered?" Dai Huadong pointed to the input method in the corner of the light screen and said.

Xu Yiyi shook his head: "Generally, words plus letters and numbers, this is ...... There may also be symbols. The possibility of a specific vibration frequency or a specific pressure as a hidden password cannot be ruled out. ”

...... "What's the matter with your academy getting a password and making it so frustrated?" What the hell is that particular vibrational frequency? Can this kind of thing also be used as a password? Even nuclear weapons don't have such a difficult password to deal with!

"That is, we can't open it at all right now?" Dai Huadong looked at Xu Yiyi.

Xu Yiyi turned her head: "Yes...... Yes......"

Dai Huadong looked at the sky blankly, ah...... Sky is blue...... What a fart! It's in the room! How is it possible to see the sky! Made, that traverser has been in this situation! Finally bought a good thing, but it couldn't be opened?

Dai Huadong slapped the box: "This is still a fart!" Who the hell can hit this thing! ”

"The password is correct." A cold, mechanical sound came from the box, and with a click, the box opened.

“…… In other words, this thing is voice-typed? Dai Huadong was silent for a while and said.

"Uh...... This is probably the latest secrecy measure. Xu Yiyi said with some uncertainty.

"%@#$&#@##" Dai Huadong thinks this academy has to be so painful to get such a password? First, the keyboard light screen is displayed, but it is actually a voice password......

"Forget it, let's see what's in it first." Dai Huadong looked at the box.

Inside the box is a very small tank that feels like a model.

"Is this a remote-controlled bomb?" Dai Huadong remembered that the bomb could be mounted on a remote-controlled toy to kill and injure the opponent after reaching the target, but this is what it contains? Wait, it seems to have been said before that the shell of this box uses space folding technology, so this box is ......

"It's using space compression technology, and it looks small, but it's actually huge." Xu Yiyi explained.

Dai Huadong nodded: "I'll just say it." Is this a real tank? ”

"Hmm...... I'll take a look at ......" Xu Yiyi looked at the letters in the box, "The Sherman M1 standard tank, because it does not meet the corresponding standards, is stored as a defective product." ”

"Sherman...... By the way, what does your Sherman look like there? "Things with the same name in different worlds are not necessarily the same, so Dai Huadong thinks it's better to understand what Sherman in Xu Yiyi's world is like first.

Xu Yiyi thought for a while and said, "I've just heard that it is said to have a rate of fire of six rounds per second, which integrates blasting, armor piercing, and burning. I drove a replica during military training, but the rate of fire was far from enough, only one-sixth. ”

"......" the corners of Dai Huadong's eyes twitched fiercely, what the hell is this? Are you sure you're copying Sherman rather than turning fantasy into reality? Is there still 59 and 38 big covers?

"But this seems to have been developed later, and the rate of fire is twice as high as the imitation." Xu Yiyi pointed to the string of English and said.

"What weird stuff is your weapons department working on, why do I think your tech tree is getting crooked?" Dai Huadong said helplessly.

Xu Yiyi tilted her head: "Is there one?" At that time, the technology in our world was really advanced. The footage that remains behind proves this. They even developed a fruit that can be eaten and thrown out to explode. ”

“…… I can be sure that your technique is completely and completely crooked......" Dai Huadong was a little helpless.

"But Dai Huadong, you haven't been to our world, how do you know?" Xu Yiyi said.
