Wang Yong asked Matthew Reagan what they were studying, and Matthew only said that Reagan and the four of them, plus Sophia, Samantha and Lukya, were mysterious every day, and the door of the alchemy room was always closed, so Matthew didn't know what Reagan was doing.

Walking into the cave, Wang Yong went straight to Regan's alchemy room, as Matthew said, the door of the alchemy room was closed, and no sound could be heard inside.

Wang Yong knocked on the door, but there was no movement for a long time, just when Wang Yong was about to give up and turn away, the door was pushed open suddenly, Wang Yong who was standing at the door couldn't dodge being knocked squarely, and after a scream, he squatted on the ground with a bleeding nose, and the corner of his eye saw a figure running at a wind-like speed, ignoring Wang Yong behind the door.

With Wang Yong blocking the disaster, Light Spirit and Shadow Dance were not injured, but when they saw Wang Yong's red nose, they couldn't help but cover their mouths and snicker. After a while, Wang Yong wiped away his snot and tears, turned his head and asked Qingling: "Have you seen who it is?"

Light Ling nodded a little gloating and said, "Well, it seems to be Lukeya, who ran into the bathroom." ”

Wang Yong rubbed his nose and said viciously: "He will be good-looking in a while." With that, he walked into the alchemy room.

As soon as he walked into the alchemy room, Wang Yong was stunned, because in the open space not far in front of him, a hollow cylinder with a thickness of two meters was placed on a sturdy wooden frame.

The hole in the middle of this cylinder is about the thickness of an arm, and inside is a layer of finger-thick surface crystal, and the outer surface of the cylinder is also wrapped in spar, which looks shiny and shiny. However, through the translucent spar, Wang Yong can see that the main body of this cylinder is not a spar, but a black metal three fingers thick inside.

Wang Yong circled around this strange thing several times, except for finding countless large and small magic arrays engraved on the spar, the more he looked at it, the more it looked like an ancient earth cannon.

Wang Yong's arrival did not attract the attention of the others, and at this time, Maureen was controlling her magic flame to calcinate a piece of Mithril. Regan, on the other hand, stood beside Maureen and poured the melted Mithril water evenly into a hedron mold, turning it into a curved and cumbersome thread of Mithril that did not overlap in the slightest.

Samantha and Sophia crouched on the floor of the workbench, constantly making hedron molds according to Rook's request, while Quentin was constantly experimenting with something on a miniature magic circle, and recorded every change in detail.

Wang Yong stood in front of the cannon-like thing and looked at it carefully, but with Wang Yong's understanding of the magic array, he couldn't understand what kind of magic array was engraved on it.

At this time, Maureen had just melted a piece of Mithril. Wang Yong hurriedly leaned over and asked, "Mo Lin, what are you studying?"

Regan raised his head and saw Wang Yong coming, rubbed his two dark circles and said excitedly: "You came just in time, we will finish it soon, let's go outside together to try it later." ”

Wang Yong pointed to something like an earthen cannon and asked curiously, "What is that?" Reagan was very dissatisfied with Wang Yong's use of the word 'thing', but he couldn't think of a better term, so he simply let Wang Yong call it that.

Reagan pulled Wang Yong to the earthen cannon and said with a show off: "This is the magic cannon we have been studying for a long time, how is it?

Wang Yong had vaguely guessed before, so he was not surprised when Reagan said the name of the cannon. Instead, he asked curiously, "What's the use?"

Regan stroked the earthen cannon and said, "Theoretically, as long as there is a magic crystal, even ordinary people can control it to launch magic, and it is a large-scale magic. ”

Wang Yong asked calmly: "What about the range, power and range?"

Reagan shrugged and said, "There are no experiments yet." I don't know about this, but theoretically, the range should be above 800 meters, and the power is about the same as that of mid-level magic. The range is a little bigger, though. ”

Wang Yong thought for a while and asked, "Is it a straight line attack or can it be projectile?"

Reagan asked puzzled, "Does this hate matter?"

Wang Yong nodded vigorously and said, "Of course it's important, this is the environment that determines the application of this kind of earthen cannon." If it can only be fired in a straight line, then it can only be placed in a high place. For example, on a city wall, on a hill, or on a high ground, but if you can throw it, you can also use it to fight the enemy head-on on the plains. ”

Reagan tilted his head to look at Wang Yong, and asked curiously, "Why aren't you surprised at all? What a great invention this is?"

Wang Yong pouted and said, "Did you invent it?" I really want to see it in some book. ”

Regan's face turned red when he heard this, but Maureen said: "Why didn't we invent it?" What you have seen before should be the magic cannon, that thing can't be made without the magic master-level magic attainment, and although we borrowed some theories from the magic cannon and some magic arrays, the main structure of the entire magic cannon and the magic array were designed by ourselves. ”

Rook also pouted and added, "Also, we have added a few formations to it. ”

Quentin concluded, "So, this magic cannon is what we invented. ”

Wang Yong saw that he had aroused the anger of the people, and hurriedly raised his hand in surrender and said, "I said it wrong, can't I say it wrong?" Quentin and Luke snorted coldly, and then continued to bury their heads in their work.

Next, Reagan and Maureen sang and introduced the magic cannon to Wang Yong, the main body of the magic cannon (that is, the black metal) is a high-temperature resistant alloy made of a lot of alchemy materials and several metals, it is said that this metal can not melt in magma, but the toughness is not strong, if this metal is made into a big sword, then the same size of iron sword can easily cut it. And this metal also has a disadvantage, that is, it cannot carry magic arrays and formations, in other words, it has a repulsive effect on energy.

Needless to say, the outer layer of this black metal spar is naturally used to carry the magic array, but the lines engraved on the spar cannot withstand the huge energy after excitation, so it has to be made of the same shape of metal wire with Mithril, which is intended to carry a huge and ferocious energy flow, and this is what Regan and Maureen just did.

As for the bracket of the magic cannon, it is not very important and has no technical content, so Reagan and they have not considered it, and they use a wooden frame as a support for the time being.

Qingling didn't have the slightest interest in alchemy, and after chatting with Maureen for a while, he went to play with Xiaobai, and Shadow Dance didn't have any interest in these, but he still stayed. After Lukia came back from going to the bathroom, Wang Yong also forgot to settle accounts with him, and kept asking his own questions while listening to Regan's explanation of the role of those magic arrays on the cannon.
