Seeing that the situation was a little out of control, Mo said that it was Lu Feihu, and several other company commanders also hurriedly ran to him and shouted: "Quiet, quiet......"

Lu Feihu watched Xu Zhi come out, his eyes were very complicated, and he also very much hoped that Xu Zhi's results were real. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 info But reason, reason, told him that Xu Zhi's results were impossible. Not to mention that Xu Zhi didn't go to class for a day, he only read the textbook for dozens of minutes, and the last question that was not ready to give students a score, let alone Xu Zhi, even his own level, he couldn't answer it.

"Xu Zhi ......" Lu Feihu stretched out his hand to shake Xu Zhi, and said lightly, "First of all, congratulations on your high score, but before announcing that your results are valid, you have to answer me three questions!"

Suddenly, the whole playground was quiet again, everyone understood what was happening, and Lu Feihu explained one more word. Xu Zhi's back from the night before was still in their minds.

"Okay!" Xu Zhi's expression was even more flat than Lu Feihu's, and he replied with a smile, "I guess it's because the professors at the base don't believe in my grades, right?"

Seeing Xu Zhi so calm, Lu Feihu had confidence in this young man for no reason, his heart was relieved, and he nodded with a smile: "Not only don't you believe it, it's just doubtful! And I also tell you, everyone suspects you of cheating! If you don't answer any of the three questions in my hand correctly, your grades will not only be invalidated, but you will also be criticized by the academy, and as for other punishments, it's not for me to know!"

"Okay!" Xu Zhi replied without hesitation, "I am willing to accept this test to show my innocence!"

"You're serious!" Lu Feihu became more and more fond of this calm teenager, and he waved his hand, "No one doubts your innocence, but your grades are too incredible." ”

As he spoke, Lu Feihu took out an envelope from the bottom of the clip and said to Huang Minghui: "Four companies, one platoon, one squad leader!"

Huang Minghui hurriedly ran over and saluted, "Here!"

"He is your soldier......" Lu Feihu handed the envelope to Huang Minghui and said, "This is a question from Colonel Ji, you will open it!"

"Yes!" Hearing that it was actually Colonel Ji himself, Huang Minghui's expression tightened, and he replied in his mouth and took the envelope. Sure enough, the envelope was sealed, and there were two big characters "Ji Ming" on it.

Huang Minghui took a deep breath, turned his head to look at Xu Zhi, opened the envelope, he looked at it, and said to Xu Zhi: "Xu Zhi, I'm starting to read the question!"

"Okay......" Xu Zhi replied with a clear gaze and a faint look at Huang Minghui.

"This is a ......question of judging right and wrong," Huang Minghui read, "If you think the question is wrong, you need to point out what went wrong!"

Xu Zhi did not answer, and Huang Minghui continued: "The semi-free bolt-type principle is an automatic principle that delays the recoil of the bolt through a specific device, reduces the chamber pressure to a safe degree, and then recoils. Like the free bolt principle, it does not have a real locking device, but only delays the bolt for a certain period of time by increasing the frictional resistance of the bolt recoil and changing the quality of the recoil parts. This type of weapon is more adaptable to guns and bullets than free-bolt weapons, and can be used for both high-power and low-power ammunition. There are many ways to delay the recoil of the bolt, such as using rollers (German G3 automatic rifles), using bevels and friction (American M1918 Thomson submachine guns, M50 Lessing submachine guns), using gunpowder gas pressure (German P7 pistols), etc. ”

After speaking, Huang Minghui put away the paper, looked at Xu Zhi, and waited for Xu Zhi to answer.

Mo said that Huang Minghui was looking forward to Xu Zhi's answer, and on the playground, more than 400 students were waiting for Xu Zhi's answer, and only the naval soldiers training in the distance came from a burst of sounds.

"System, how do you answer this!" asked Vision in a low voice in his heart.

A cold voice came out of Envision's mind: "Sorry, military knowledge is too old to answer. ”

Looking at Xu Zhi again, he smiled slightly, although the smile was faint, it was enough to intoxicate hundreds of girls, although Xu Zhi had not answered, they already had great trust in Xu Zhi.

But I heard Xu Zhi speak: "This question ...... Not true!"

"What's wrong?" Lu Feihu couldn't help but ask, because this question was the first time he had heard it, but no matter how he heard it, he felt that it was correct!

"It......'s very simple," Xu Zhi said with a smile, "The American M1928 Thomson submachine gun is not the American M1918 Thomson submachine gun!"

"Okay!" The girls cheered again, although they didn't know if Xu Zhi answered correctly, "Xu Zhi, Xu Zhi ......"

"I'm sorry......" Lu Feihu said, sending everyone's mood to hell.

"Is that wrong?" everyone shut up and looked at Lu Feihu.

Lu Feihu continued: "The answers to the three questions are all sealed in one envelope, and unless you answer all three questions, I don't know if you are correct or not!"

"No problem!" Xu Zhi nodded, "Please continue to ask the instructor!"

"Vision......" Lu Feihu looked at the prospect next to him, handed him another envelope, and said, "You can ask this question!"

"Okay!" Vision took the envelope, looked at it carefully, raised his hand, and said, "I can testify that this envelope is sealed and has a signature on it!"

After watching everyone finish reading it, Yuanjing tore open the envelope and looked at the question inside, he also smiled bitterly and said, "Xu Zhi, this question is similar to the one just now." The barrel offset locking mechanism is mostly used in pistols that adopt the principle of short recoil of the barrel, such as Browning high-power pistol, Polish Radom TT-33 pistol, Soviet Tokarev ZIS35 pistol, American Colt M1911 pistol, etc. Are you right or not?"

None of the people spoke, and their eyes fell on Xu Zhi's face, the young man's handsome face was set against the background of the military uniform, extremely righteous and calm.

In this calmness, a smile was revealed, and Xu Zhi's voice sounded: "This is also wrong, it should be the Soviet Tokarev TT-33 pistol and the Polish Radom ZIS35 pistol." ”

Yuanjing shrugged, handed the envelope to Lu Feihu and said, "I don't know if it's right or wrong, this sentence is not mentioned in the gun theory." ”

"Report to the instructor!" a voice rang out from the queue.

"What's the matter?" Lu Feihu took the envelope and looked up, only to see a girl in military uniform raise her hand and shout, "I believe that Xu Zhi will not cheat, but I want to open the last envelope with my own hands and let him confirm my trust in him!"

As soon as the girl's words came out, the whole queue of "woo woo ......" howled again, because although she didn't say anything, how could the word trust be easily said from the mouth of a girl, let alone in front of more than 400 classmates?

"Dongfang Hui?" Xu Zhi turned his head and looked at the girl very strangely, puzzled.

"Hmph......" At the same time, I don't know that several girls snorted coldly in their mouths and noses, obviously they were annoyed that Dongfang Hui took the lead.

"Out of the ranks!" Lu Feihu thought for a moment and said secretly.

"Yes!" Dongfang Hui ran out of the ranks. Dongfang Hui is already beautiful, and she is even more heroic in a military uniform, her white military uniform can't stop her convex lines, and the hair scattered on her forehead is even more charming.

"Three rows and three shifts in a row, Dongfang Hui was ordered to go out!" Dongfang Hui said with a salute after running to Lu Feihu and standing.

"This is the third question...... Lu Feihu handed the third envelope on the clip to Dongfang Hui and said solemnly, "I hope you can testify!"

"No problem!" Dongfang Hui bit Sakura's lip, took the envelope, looked at Xu Zhi with a pair of wonderful eyes, chuckled, carefully checked the envelope, then tore it open, and read, "The locking card iron offset locking mechanism, also known as the fish gilll plate locking mechanism, is used more in air-conductive weapons. There is a piece of locking card iron that can be abducted on both sides of the bolt that adopts this mechanism, when the bolt closes the breech forward, under the effect of the bolt frame locking inclined plane, two pieces of card iron are deployed against the locking support surface on both sides of the receiver to complete the locking; when the bolt frame is retreated by the piston, the bolt frame unlocking inclined plane retracts the two pieces of clamp iron again, and is separated from the locking support surface on the receiver, and the bolt can retreat and unlock. This locking structure can be seen on many firearms designed by the Soviet light weapons designer Degtyalev, such as the Dsh anti-aircraft machine gun, the RPD squad light machine gun, the RP-46 company machine gun, the DP/DPM light machine gun, etc. Xu Zhi, is this sentence correct?"

Xu Zhi was stunned for a moment, and looked at Dongfang Hui with some puzzlement, Dongfang Hui's heart "chuckled", and the confusion in her eyes was like a broken grass on the side of the road, which made her heart hurt.

"Can I take a look at this question?" Xu Zhi asked Dongfang Huidao.

"This ......" Dongfang Hui hurriedly looked at Lu Feihu.

Lu Feihu nodded slightly, when Xu Zhi took the letter, looked at it, and said with a smile: "I understand!"

As he spoke, he returned the letter to Dongfang Hui. In a word, Dongfang Hui's mood is like a white dove spreading its wings, taking off with great ease.

"This sentence is also flawed, it should be the Dshk anti-aircraft machine gun, just now Dongfang classmates read it, I didn't understand!" Xu Zhi replied confidently, "There should be an extra K letter in the textbook." ”

"Papapa......" All the students clapped their hands again, and Dongfang Hui's face also blushed with excitement.

Immediately, Xu Zhi said: "These three questions, as well as the last question in yesterday's exam, are all from the "Principles and Construction of Automatic Weapons" published by the National Defense Industry Press, and we are studying the "Basic Principles of Firearms" published by the National Defense Industry Press! Coincidentally, I am a military fan, and I turned these two books through before the college entrance examination!"

Lu Feihu didn't speak, opened the last envelope, he looked at it, and applauded: "Yes, Xu Zhi, you have answered all three questions correctly! Congratulations, your record is valid, and you are a well-deserved perfect score king!"
