Gao Wen always pops up some inexplicable sentences and words. Sometimes even phrases that others can understand will be combined into an incomprehensible state in his mouth. Amber has long been adapted to this situation, and her method of dealing with these obscure sentences is also very simple - that is, give up thinking.

"Just say what this is," Amber rolled his eyelids, "New magic machine? Alchemy device? Or the weapon you mentioned last time?"

"There will not be a sign of the Military Machinery Institute on the report of Magic Machinery and Alchemy," Gao Wen smiled and pointed to the top of the report, then stood up, "Come on, let's go and see this brand new weapon."

On the weapons testing ground on the south bank of Baishui River, relevant preparations have been completed.

What was delivered to Gao Wen was a report that indicated that the finished product had been assembled and was waiting for the lord to accept it. While the report was delivered, Heti had ordered the personnel from the Mechanical Research Institute and the weapons testing ground to prepare for the first test. When Gao Wen and Amber arrived at the test ground, this area had been blocked by the soldiers of the Cecil Combat Corps and informed the residents of the northeastern district of the city in advance about weapon testing. The new equipment of Cecil's lord was often accompanied by huge explosions, so under normal circumstances, it is necessary to issue a notice in advance.

This is a weapon that Gao Wen has high hopes for, and it is a "temperature and aggravation project" that was put on the agenda after the second Cecil defense battle. It is naturally very eye-catching. Basically, people who participated in the research and development or were qualified to watch arrived at the scene, including Byron and Philip... The Cavaliers, including technical leaders such as Jenny, Carmier, and Nicholas Egg, and Hetty and Rebecca were also on the scene.

This is the case in the early stage of entrepreneurship. There are only a few people in the top-level team, and because of insufficient staff, they often need cross-soft help, so that whenever any major results come out, they will all come to watch.

As soon as Gao Wen showed up, Rebecca happily trotted up to meet him: "Sir Ancestor! Sir Ancestor! The 'art launcher' you want is ready!"

Last time Gao Wen was chatting with the silly roe deer, he couldn't help but say "Explosion is art", but the girl was directly wrong...

Gao Wen pressed Rebecca's head and his eyes fell on the war machine that had just walked off the mechanical assembly station.

It is very large, with an acceleration track of up to three meters and a total height of nearly two meters. Its shape is very close to the theoretical model constructed by Gao Wen in the "simulation experimental field", but there are very different details.

It has four parallel metal tracks, which are still fixed on the base according to the cross structure. Two acceleration guides, and two directional guides are used to fix the trajectory of the shell and stabilize the ballistic and reduce friction. However, unlike the tracks simulated by Gao Wen in a virtual environment, the entire acceleration-directional structure in front of him has been additionally reinforced. There are three "fixed rings" made of solid steel plates to firmly combine these four guides. Judging from the magic runes shining on the fixed rings, they may also have the function of assisting the rails to release waste energy and reduce magic interference.

The entire acceleration structure is installed on a roughly triangular base, which is covered with steel plates. Although it is still a prototype, the powerful metal control ability of Nicholas egg still makes the base look very standard and precise. On the side, you can see the lines formed by the slightly shiny magic material, and on the back you can see the control joystick and the shaking handle. In the part connecting the triangle base and the acceleration structure, Gao Wen noticed the huge gears and rotation shafts, which were obviously used to adjust the elevation angle of the track.

"According to your drawings and improvement suggestions, I have redesigned its adjustment mechanism so that it can adjust the pitch angle in a larger range. The base also reserves a rotating disc connected to the gun position, which can eventually allow the entire gun to rotate freely," Nicholas Funny Egg floated over and made a metal vibrato sound from the sphere. "The upper positioning guide adds the 'cannon sight' you mentioned. In addition, Carmire has also redesigned the rune arrangement of the acceleration track, which can be more conducive to the release of waste energy, which can improve the overall life of the track."

Gao Wen turned his head to look at Carmier, thinking that this ancient mage was indeed a little obsessed with the "service lifespan"...

"This is the 'cannon shell' it uses," Carmier seemed to guess what Gao Wen was thinking, and made a little embarrassed to break the silence. He controlled the hand of shaping and sent a metal magic device placed not far away to Gao Wen. "I prepared a test bomb without explosives and a complete live ammunition - except for replacing the explosives with the same weight of gravel, the test bomb and live ammunition were completely consistent in all aspects. This was a test bomb."

Gao Wen looked down at it - this magical shell has a completely different shape from the earth shell he remembers.

It has no cylindrical bullets and conical bullets, but it is more like a small, weird obelisk.

Its bullet body is rectangular, with a depression on the top and bottom to match the directional guide rails in the acceleration track. The rear and front end of the bullet body, which looks like a small gold tower, are engraved with runes of "Blessing of the Wind". Those runes are now dim - obviously, they are not charged.

And there is no magic structure connected to the shell body.

"Where is the energy of the wind rune group coming from?" Gao Wen asked curiously.

"Recharge during the acceleration in the orbit," Kamair explained. "The shells are consumable items, so we need to find a way to save costs, because the wind runes on them only need to let the shells fly for a few dozen seconds at most after activation, so there is no need to consider allowing it to carry independent energy. For a basic spell effect that only has one level, as long as some crystal dust is added to the material when drawing the magic array to have basic energy storage properties, the energy accumulated in the magic array is enough to allow the magic to run for about a minute."

Gao Wen was a little surprised: "This is a good idea - what you think?"

"I hope it is, but it's Rebecca's idea," Carmire turned into a humble gray-blue and moved a little away to let Rebecca step forward. "I have to admit that your descendants' talent in invention is simply enviable."

Rebecca immediately walked up with a look of "I'm super awesome" and almost raised her face in front of Gao Wen: "I got inspiration from your magic capacitor - as long as you add some extra magic guide structure to the acceleration track, drain some of the energy in the cannon seat, and then treat the runes containing crystal dust on the cannon shells as weak magic storage crystals, then the entire acceleration track will become an open magic capacitor. Although the shells stay in the acceleration track for a short time, coupled with the contact stage between the shells and the tracks during loading, this charging process is completely sufficient!"

Gao Wen knew it in his heart and felt that this should be the case. Only Rebecca, who had been in poor days, could he always put the concept of "compressing costs to achieve mass production" he taught. How could Kamier, who lived in the era of a rich man, have this idea of ​​racking his brains to reduce costs? If it were the Gondor Empire back then, those tyrants would have had a hard work style without using a whole piece of blue crystal carvings that were shot out...

Gao Wen praised Rebecca for a few words, and then smiled so beautifully that the girl turned her head and looked at the soldiers on standby next to the rail gun: "The technical details will be discussed later. I can't wait to see how it actually performed. Let's start with the test bullet?"

"This is the most in line with the process." Carmier said, controlling the power-shaping hand to deliver the test bullet to the soldiers.

According to the operating procedures that had just been learned, the soldiers immediately began to load this huge war machine.

They opened the loading port on one side of the gun seat, pushed the shell into it, and then used the push rod to snap the shell into the track, then closed the loading port, adjusted the angle of the acceleration track, and activated the charging structure for overload (scientific name is Rebecca Efficiency Module)...

The magic lines on the cannon mount gradually brightened, followed by the runes group on the entire acceleration rail, and a strange, low buzzing sound began to sound.

Another soldier who was operating the cannon was already standing behind the side of the cannon seat and placed his hand on the handle for firing the cannon.

The Byron Knight issued an order: "Fire!"

The soldier then pulled the handle.

The shell was pushed into the acceleration section by the base repulsive mechanism, and then accelerated rapidly under the action of a series of repulsive runes. All sounds gathered into a sharp explosion. As the entire acceleration track retreated violently within the base, a shiny metal device rushed out of the track wrapped in a light green cyclone and flew into the clear sky with a sharp whistle.

Compared to the "cannon" that relies on gunpowder explosion to push the bullet body, the sound of this acceleration rail cannon is much smaller, but the sudden explosion still scared Rebecca and Hetty - Jenny exclaimed softly and covered her ears half a beat slow.

And after a few dozen seconds, on a distant hillside as the target, Gao Wen saw a sudden rise of smoke and dust.

He smiled: "If the gun is fine, we should use live ammunition - that's more intuitive."

Several technicians from the Institute of Mechanical Research immediately stepped forward to check the condition of the rail gun, and soon a report came: "The track is in good condition! The charging structure and overload structure are in good condition! All moving parts are connected securely!"

"Live ammunition!"

The soldiers repeated the process of the first launch again, and this time, the one pushed into the acceleration track was a live ammunition loaded with dozens of kilograms of Rebecca crystals.

Rebecca, who knew how much the crystal he had made, got behind Hetty immediately, immediately, and Hetty subconsciously hid behind Gao Wen. Amber looked at the reactions of the two, thought carefully, and analyzed calmly, and became illusory. When the situation was wrong, he jumped directly into the shadow world.

Then, the rail gun was fired.

There was still a sudden explosion, and a metal device wrapped in a light green airflow rushed out of the track, even Gao Wen and Kamier could only barely chase its flight trajectory - the shell did not explode immediately after it was out of the "bore", its bullet body and the fuse insurance mechanism withstood the test, and the entire shell flew through a long parabola in the air, and after a few dozen seconds, it hit the hillside in the distance.

There was a loud bang, as if thunder exploded, and countless earth and rocks rose into the air during the explosion, and the fire ball generated by the magic explosion rose into the air.

Amber, who was about to drill into the shadow world, stood there in a daze.

She stared blankly at the hillside that was covered by smoke, dust and stones and had a huge fireball soaring into the air, and suddenly understood what "negotiation means" that Gao Wen had previously said.

Under any circumstances, anyone who uses this thing to negotiate with her will definitely cooperate...
