"The stronger the wind, the more my heart is swinging. ”

Before dawn, Yunfeng returned to the academy alone. The cold wind is cold, the old horse knows the way, walks quickly, and hums a little song all the way on the horseback, and the mood is cheerful.

"Blow, blow, my pride indulges ......"

If anyone hears the song of a ghost crying wolf at night, he will be frightened.

"Where have you been going to be chic these days?" As soon as he returned to the academy, he was locked by Chen Ming and asked.

Yun Feng put his hand against Chen Ming's forearm, and said busily: "Where, it's just to scatter your heart." ”

"Scattered?" Chen Ming will be skeptical about this, it should be said that he is very skeptical, "Scattering is not called to us, and the money won is not our share, so please rub it a few times." ”

Chen Ming's request is reasonable, just Yuan Yuan and a few people bother to make strategies for him and collect opponent data, not to mention a few meals, even if the bonus is half of the opponent's award, it is not too much.

However, Yun Feng is currently inseparable, and he has to treat Sheng Nan and Shu Ye at the same time. This time I came back, which is to enter the second part of the book and formulate the next stage of the medication plan for Uncle Night.

Yun Feng had to apologize for this: "Next time, next time, definitely." ”

Chen Ming let go of his hand, Yun Feng was able to breathe, touched his neck, and just as he was relaxing, he suddenly remembered a voice behind his ear: "There is a smell of rouge." ”

Yun Feng was startled, and when he turned around, he found that Yu Mengdie was behind him at some point.

You must know that Yunfeng is extremely alert, but Yu Mengdie can always appear silently.

Chen Ming immediately changed his eyes and said, "It seems that you have been quite busy recently, how are you?" ”

Yun Feng immediately raised his sleeve and sniffed it, but he didn't smell anything, and he had always been very confident in his sense of smell: "Where, Senior Sister Yu said with a smile." ”

Yu Mengdie shook her index finger and said in an unquestionable tone: "There is more than one, believe me, women have a very accurate sense of smell in this regard." ”

Yun Feng wanted to marry no one and couldn't marry a woman like Yu Mengdie, it was too terrible.

"Yo, I can't see that our little strong son is so amorous. Chen Ming believed in Yu Mengdie's judgment very much, and once again used the throat lock technique, thinking that Yun Ji looked honest on weekdays, but he was deceived by him.

"Confess and be lenient, and if you want to refuse and welcome. ”

"Bang!"

Just as a few people were fighting, a wave of steam swept over without warning!

Rao is several people reacted quickly, but they couldn't avoid it and were blown to the ground.

The room was suddenly messy, and the tables and chairs were crooked. Yuan Yuan scolded and got up, and said, "Jiuli!

Several people pushed open the broken door, and the sight of them suddenly made them dumbfounded.

It was originally a three-storey attic, but the upper two floors have been flattened, and the debris is scattered all over the ground, and it is difficult to find a complete building board.

And the cliff behind the building was blown out of a big hole, the broken rocks flew away, and the farthest one was even thousands of meters away, and Yunfeng and several people were almost not stoned to death, and they were almost not bombed into scum.

Shen Jiuli ran from a distance, his face was like carbon, if it weren't for the two eyes rolling around, he wouldn't know that it was a person.

"Misfire, misfire. Shen Jiuli touched his head and apologized embarrassedly.

Chen Ming spat out a mouthful of sand and dust, and scolded: "Take your sister, murder." ”

A few people scolded, surrounded and stepped forward, and beat Shen Jiuli with a fat beating, it seems that this kind of thing happens a lot.

"I won you a few gold coins a few days ago, and today I will take the opportunity to retaliate. Chen Ming said.

"My clothes, these shoes, they were all just bought, the latest this year, and how to calculate the mental damage fee. Yu Mengdie said.

"I'm scared to death of the baby, and I have to eat a good meal to suppress the shock. Yuan Yuan said.

Shen Jiuli climbed to the feet of Yun Feng, tugged on his sleeves and legs, and tears flowed down his eyes: "Brother Yun, save me." ”

Yun Feng smiled, and just when Shen Jiuli thought he was saved, he stepped forward and rounded his fist: "Nima, I almost killed Lao Tzu ......"

......

......

After everyone finished beating up, they were also very curious about what Shen Jiuli was doing, and he had such great power.

Several people followed Jiu Li, and their eyes suddenly lit up.

"Wow Ka Ka ......"

Chen Ming circled around the thing in front of him, looked up and down carefully, and said, "This is...... Artillery?"

In a meadow, there was a long cylinder, as thick as a calf, about six feet, without wheels, fixed to the iron grooves on both sides. However, it is different from ordinary artillery, and the gun body is more complex.

"Haha......" Shen Jiuli smirked, "How about it, I haven't seen it." This is a new type of artillery that I have developed, and the range is three times that of conventional artillery!"

Yun Feng has seen artillery, and there is one in the General's Mansion. But compared to the one in front of me, it is really too simple and rude, whether it is the feeling of the materials or the essence of the structure, just like the difference between a broken mud bowl and fine porcelain.

Cheng Liang's cannon body gave people a sense of coldness, and Yun Feng asked, "Is it this little guy who caused the power just now?"

Shen Jiuli's pride was beyond words, and he was very satisfied with the expressions on the faces of several people: "Don't look at this guy, it's just like that, he can be very powerful." ”

"Even if this little guy took medicine, the gunpowder would not be so powerful. Yuan Yuan also stepped forward to investigate, and there was still gunpowder in the muzzle, but even if the caliber of the gun was doubled, it would not have such an effect.

"It's the Magic Crystal. Yu Mengdie sniffed the muzzle of the cannon and said her own inference.

Looking at Shen Jiuli's appreciation, Yun Feng knew that Yu Mengdie's calculation was correct. I thought to myself that this guy was too perverted, and he could smell it.

Yuan Yuan suddenly said: "Silver Python Blue Dan!"

Everyone was taken aback, and they all looked at Shen Jiuli.

"It's worthy of Yuan Yuan. Shen Jiuli said with a smile.

Everyone suddenly realized that the buyer behind the silver python demon core that day was actually Shen Jiuli.

"Tut-tut......" Several people couldn't help but sigh, Jiuli is really a loser, and a cannonball costs 30,000 gold coins!

"Scientific research, it must be funded. "Shen Jiuli is not distressed, but today's effect is worth it.

A few people came to his lab, which was full of equipment and was like a recycling dump. The walls are covered with drawings, precisely the design composition of the previous gun, which has undergone several revisions from the design to the finished product.

"What is this cannon called?" Through the drawings, Yun Feng more intuitively understood the internal structure of the artillery.

When he saw the final drawing, there were a few annotations: "Kleptural cannon?"

"Why don't you call for a masturbation. Regarding Shen Jiuli's naming aesthetics, Chen Ming did not dare to agree.

A few walked around, and they were interested, but Yunfeng was very interested in the cannon, and there were many interesting things in the laboratory, which seemed useless, but I had to admit that the creativity was infinite and the brain was open.

It seems that Shen Jiuli advertises himself as a genius, which is not unreasonable, Yun Feng feels that to be precise, he is a geek.

Needless to say, the power of the Kebour cannon is on the battlefield, and its lethality is bound to increase by several orders of magnitude compared with traditional artillery, which is enough to have a huge deterrent effect.

"Why do you want to reduce rifling?" Yun Feng looked at the drawings very carefully, and found that there was a draft that was obviously better, but in the end it was not adopted.

Shen Jiuli didn't expect that Yun Feng had a lot of research on this, if he wasn't a person who was proficient in equipment, it would be difficult to see the difference between the two.

"These were two different designs. Shen Jiuli pulled out a thick design draft from the shelf. The walls are just sketches, and the real setup plan is not something that can be done with a few pieces of paper.

Shen Jiuli pointed to a part on the map and said: "According to my previous concept, the shell is composed of a warhead and a shell, the bottom is filled with gunpowder, and it is fired with a firing pin, and the explosion instantly flushes the demon core. ”

"But if this is the case, the impact force at the moment of explosion will be increased several times, and with the existing iron ore hardness, it is not enough to withstand the momentum, and at most three shells, the barrel will be scrapped. ”

"Before that, I had blown up two doors. Shen Jiuli said, his heart was still dripping blood, and the cost of two artillery pieces was already expensive, not to mention the expensive magic core.

This result was expected by Yunfeng, and the reason why he proposed it was to restart the plan: "If you use Xuanbing Iron, is it feasible?"

As for the hardness of the cannon barrel, Yun Feng considered replacing it with Xuanbing iron, and his Xuanbing carriage remained in General Elbis's mansion.

"Do you have it?" Shen Jiuli's eyes lit up when he heard Xuan Bingtie. At the beginning, he put a lot of effort into improving the hardness of the cannon barrel, and he also thought of Xuanbing iron, but the latter was too scarce and could never be found.

I heard from the elders of the family that a customer once used Xuanbing iron to build a carriage, and he asked someone to inquire, but the other party did not leave any information and could not be contacted.

"It's not a new iron mine, it's a refurnace. Yunfeng added.

"I'm not sure it's feasible, but it's worth a try!" Shen Jiuli pondered with his eyebrows, although the hardness of Xuanbing Iron is high, it has not been tested after all, and the result is not easy to say.

"When will your goods arrive?" Shen Jiuli said about the goods, which naturally referred to Xuan Bing Tie.

"It's going to take some time, I'll tell you when it's time. "It will take some twists and turns to pull the carriage from the general's palace.

......

......

The next morning, the clouds and wind tumbled down the back wall, and he was already familiar with this move.

Behind him, several heads poked out, looking at the background where Yunfeng was walking eagerly and whispered.

"This kid, sneaky, must have something to hide from us. It was Chen Ming who spoke.

"I don't admit that I have such a heavy rouge smell on my body, I guess I don't know which gentle township I am in. It was Yu Mengdie who answered.

"Let's go, let's see. ”

A few people sneaked around.
