(Today's small seal pushes the first day, please all book friends to collect, red ticket ~ Tata now go to the third more ~ )

Kara ran to the front covered in sweat, grabbed Han Feng's arm as soon as he grabbed it, and his beard was about to rush into the sky. He shouted loudly, "My lord, if you don't come back, I'm going crazy!" ”

Han Feng looked at this dwarf with a frenzy in his eyes, and said with a smile: "Looking for me in such a hurry, it must be forging things and lacking materials, right?" ”

"Hehe~ It's still the adults who know me best, but the materials that are missing this time are a bit special, even the lord may not have them..."Kara said with a gloomy expression, and fiddled with the parchment roll in her hand depressedly.

Seeing that he was so abnormal, Han Feng waved his hand and said generously: "Kara, she is usually very bold, why did she become a mother-in-law this time?" What do you need, but what do you need? ”

Kara didn't even bother to wipe the sweat dripping from her forehead, quickly opened the parchment roll in her hand, pointed to the dense parts on it, and said excitedly: "My lord, this is a portable magic cannon that I researched based on the magic cannon you seized, and I named it 'Dragon Cannon'!" ”

Han Feng took the parchment scroll and looked at it roughly, there was a long barrel weapon that was somewhat similar to the rocket launcher in the previous life, about two meters long, twenty centimeters in diameter, and the inscription engraved on the outer wall of the cannon barrel was also inlaid with some demonic beast crystal nuclei. There is a trigger-like device under the front end of the dragon cannon, and at the end of it there is a shoulder carriage, and the interested ask: "How is this dragon cannon performing?" ”

At the mention of this, Kara said proudly: "The range is about eight hundred meters, and the power is about one-fiftieth of the power of the magic guide cannon, it should be no problem to kill the fourth-order horned demon or severely damage the fifth-order evil god king, and theoretically this weapon should have the characteristics of the magic cannon, which can not only break the physical defense, but also break the defense of all magic except the fire system!" ”

"Devisnia! The range of 800 meters is almost twice the range of bows and arrows, coupled with such a strong attack power, as long as the number of dragon cannons goes up, wouldn't it be invincible? Han Feng said with a twinkle in his eyes.

Kara replied with a complicated expression: "My lord, this is theoretically the case, but please take a look at the list of processes and materials needed to make the dragon cannon..."

"The cannon body is all made of Cole steel? No problem with this! The barrel liner is plated with Mithril to reduce the loss of mana? That's no problem! The outside of the barrel is an engraved inscription, and it should be plated with a layer of pure gold?! That's a bit of a tricky question. What the? Energy filling, each dragon cannon is equipped with a minimum of six or more Demonic Beast crystal nuclei? (e.g. the crystal nucleus of the scorpion), in order to reduce the high temperature emitted by the barrel, the shoulder-mounted base should be made entirely of Yuno alloy with good thermal insulation? Miso silver additionally filled high-explosive shells? ”

After reading this list, Han Feng's excitement just now disappeared without a trace, and he asked with a somewhat ugly face, "Kara, are you sure you're not joking?" We have a little bit of these materials in the list, according to the design drawings, the cost of each dragon cannon will reach at least hundreds of thousands of gold coins, not to mention the establishment, even if you make ten, you can't afford to build it. What's more, these dragon cannons are consumables in wartime, and the loss of one is equivalent to the loss of nearly a hundred iron puppets or half a large magic cannon, and we can't afford such a price! ”

Karane said: "My lord, when I developed it, I took care of the dexterity and performance, and when I developed it, I found that the cost was too high, so as soon as you came back, I rushed over to see if there was any way you had here to solve it..."

Han Feng's brows tightened together, and he became silent, and the alchemy master Shante next to him took the parchment scroll and tried to put forward an improvement suggestion, at this moment, the armor on Han Feng's body squirmed, and it automatically broke away from his body and transformed into Gaia's original appearance.

The pale golden light flashed in Gaia's eyes, and a beam of light shot out from her eyes, and the three-dimensional drawings of the parts described on Kara's drawings were quickly drawn in mid-air, and then she saw that with a wave of her hand, the various parts automatically began to combine, and soon, a golden dragon cannon appeared in front of the three of them.

Gaia pointed to the dragon cannon floating in the air and said in admiration: "Kara, I have to admire your creativity and alchemy level, you can actually use the materials of this world to build such an ingenious energy weapon, but you seem to have mistaken its development direction!" If it's just a solo or elite squad combat mode, a high-level magic scroll or a magic wand with a high attack sealed is more suitable, but it's even less realistic to fight with a large army..."

Gaia was already the second leader in the Bottle Sanctuary after Han Feng, although everyone didn't know what form of life she was, but they were all in awe of her, and after listening to her words, she explained the shortcomings of the Dragon Cannon, Kara hurriedly and humbly asked: "Lord Gaia, how can I change it to make it more practical?" ”

Gaia didn't answer, her pale blue eyes began to flicker rapidly, and soon a list and drawings with new materials written on them were engraved in mid-air, and then Gaia's voice sounded again: "Kara, take a look at this list of new materials, replace the original Adamantite Gold, Mithril, and all of them with magic metals of several grades lower, and the shoulder base can be directly changed to a cheaper Phil Iron, as for the Warcraft crystal core that is used as the driving energy, you can change it to a third-order Warcraft..."

Kara hesitated for a while, and then asked weakly: "My lord, although the cost has been reduced to more than 10,000 gold coins per piece, the range and power will be greatly reduced, plus the energy generated when the dragon cannon is fired, it is impossible for ordinary soldiers to stand it..."

"Haha, I see!" Han Feng suddenly laughed and said, "It is inevitable that the production cost will be reduced, and the power and range will be reduced, but the number can be increased by dozens of times, which is enough to make up for these two shortcomings." As for the high temperatures, it's better to send these simplified versions of the Dragon Cannons to the Fullmetal Frenzy Legion. This will not only solve the problem of high temperatures, but also make up for the shortcomings of the steel golem that cannot attack from a distance..."

Kara excitedly took out the pen and parchment roll from her bosom, and quickly recorded the changes Gaia had made. Without hesitation, Han Feng handed over all the low-grade magic metals and a small bag of third-order demonic beast crystal nuclei that he had stored.

Lampard, who rushed to hear the news, just heard the last paragraph, and hurriedly said flatteringly: "The master and Lord Gaia are too wise, so that the combat effectiveness of the Allmetal Frenzy Legion will be increased geometrically, and we no longer have to fear those ranged and flying classes!" ”

"Hehe, don't be a sycophant, you will do your best to assist Kara in making a simplified version of the dragon cannon in the future, and strive for every steel golem to be equipped with one! This ring also contains some Adamantite Gold, Mithril and some materials necessary for the full version, please ask Kara to make you a full version of the Dragon Cannon..."Han Feng smiled and threw over a spatial ring.
