It seems that bloodline and strength are indeed something that the dragon clan desperately needs. And these two things, I can just give them. It's so good, and the cooperation with the dragon clan quality inspection will be very pleasant!He thought to himself.

At the same time, Xiao Jiu was thinking that judging from the current situation, the Dragon Clan was definitely a very reliable partner in a short period of time, far more reliable than the twelve princes of the Moon Empire. Since this is the case, then Xiao Jiu naturally won't mind helping the Dragon Clan again in order to maximize the strength of his allies.

So, Xiao Jiu took the initiative to propose: "Since the nobles want to fully equip this weapon, then I will redesign a submachine gun according to the size of the nobles! ”

Youlan and the three elders were actually worried that apart from the three of them, there were no other dragons in the dragon clan who could transform into human form for the time being. After all, it is not difficult to see from the joke He Wei made with One-Eye just now that the submachine gun is too small for their dragon clan, and it is very inconvenient to use. However, it is obviously impossible for people of the same clan to transform into human forms in a short period of time. So, if the structure and size of the submachine gun can't be improved, then even if all the dragons are equipped with submachine guns, there is a risk that they will become a useless pile of scrap metal because they cannot be used.

However, Youlan and the three elders were pleasantly surprised that before they could ask, Xiao Jiu first helped them think of improving the structure of the submachine gun. And it is not difficult to see from Xiao Jiu's confident appearance that this kind of improvement is a piece of cake for it at all, and it is completely effortless!

"Thank you so much, Miss Xiaojiu. It's just that...... Has the power of the modified submachine gun been reduced, and what is the firing speed compared to the current submachine gun?" the Great Elder asked with surprise and concern.

"This Great Elder, don't worry, the power of the improved submachine gun will only increase and not decrease compared to the current one!" Xiao Jiu said as he turned on the scanner and swept the One-Eye and the Third Elder not far away up and down, wanting to combine the size of the two to design a submachine gun suitable for the use of the dragon.

Yu Lan saw that a red beam of light suddenly emitted from Xiao Jiu's body, sweeping around One-Eye and the Three Elders, and suddenly had a flash of inspiration, realizing that this was probably measuring the size of One-Eye and the Three Elders, and then tailor-made submachine guns for them according to the size of their body parts, just like humans make clothes!

So, Youlan immediately let out a low roar, turned into a dragon form again, and then shook her head in front of Xiao Jiu and said, "Give me a measure first, give me a measure first!"

No matter what, Youlan is also a dragon king, and in this case, it is naturally difficult for One-Eye and the Third Elder to compete with her for something. Therefore, the two dragons had a tacit understanding and took a step back at the same time, making way for Youlan. And Xiao Jiu will naturally not refuse this small request from Youlan. After scanning the huge blue body up and down.

Xiao Jiu said: "The size of the nobles is too large, and when they are in dragon form, they can't stretch their arms freely like humans, so I think that the guns designed for the nobles should simply be made bigger and let you use them on your backs, so that they will not occupy the dragon claws of the nobles too much, nor will they hinder the nobles from flying, which can be described as killing two birds with one stone." ”

"Make it bigger and carry it on your back?" After listening to Xiao Jiu's words, Youlan tilted her head and thought about it, and quickly asked, "Isn't the power of a bigger gun even greater?"

Xiao Jiu nodded and affirmed: "The rate of fire may not change much, but if the gun is bigger, the bullet can be made bigger, and the wound caused by the bullet piercing the target will naturally become larger." At the same time, the larger the bullet, the more ammunition the bullet will be loaded, as long as the weight of the bullet and the proportion of ammunition are mastered, the bullet can fly farther, and the killing radius will of course be increased a lot. ”

Although Youlan and the three elders only seemed to understand it, "bullets can fly farther", but the four dragons understood this one! What does this mean? This not only means that they can inflict damage on the enemy at a greater distance, but also means that while killing and injuring the enemy, their own safety has also been improved a lot. After all, there is still a saying that there is an inch long and an inch strong in ordinary weapons, and this kind of weapon that fires hidden weapons from a long distance is naturally no exception!

The successive unexpected breaths made Youlan and the three elders feel unsettled again. Especially the three elders, after listening to Xiao Jiu's words, they have already begun to win Longwangshu!

"Since making the gun and bullet bigger can make the bullet fly farther, can the little ninth girl make the gun and bullet bigger, so that the bullet can fly a hundred zhang away?" The third elder asked with a look of hope, "If the bullet can hit a hundred zhang away, can't we use this gun to shoot a round before we get close to Wuxin Mountain, and injure or even kill the other party?!"

After listening to the question of the three elders, He Wei suddenly felt that although this old dragon was annoying, his brain was quite good, and there were many possibilities from Xiao Jiu's words alone. Of course, Xiao Jiu can design a gun with a killing distance of more than 100 zhang! Moreover, Xiao Jiu can not only design a gun with a killing distance of more than 100 zhang, but can even design a gun with a killing radius of more than 1,000 zhang! After all, if 1,000 zhang is converted into meters, it is only more than 3,000 meters, and as early as ancient times, there were sniper rifles with an effective killing distance of more than 2,000 meters.

Three thousand meters, is it a long way?

"Yes, yes, but ...... If you go too far with the range of bullets, you will upset the balance between the rate of fire and the range. If you want to increase the range of bullets, you must sacrifice the rate of fire of the submachine gun. Xiao Jiu explained while using stereoscopic images to demonstrate the principle of continuous fire of submachine guns, "Therefore, if you want to make the bullet fly farther, the best way is not to make the gun and bullet bigger, but to give up the rate of fire, change from continuous fire to point fire, and at the same time change the internal structure of the gun, so that the impact force generated when the bullet is exploded is all concentrated together, and the bullet is pushed forward, so as to increase the speed of the bullet!"

For Youlan and the three elders, they couldn't understand what point shot, what impact force, and the speed of disemboweling, and so on, and they didn't care at all! The only thing they cared about was whether the bullet could fly at a distance of 100 zhang, okay or not?!
