"Yes!" Orfina shouted, shooting a healing ray at Matilda by the way, "Auntie, sister, what are you doing? Got a whole wound."

"Skin wounds, and another fight with Zhan Po, so it's a little late." Matilda explained, "Don't talk about that, let me see how good you are!"

The method of making the device has always been a secret of various countries.

The relationship between the Nalan Empire, which is also a human country, and the Spirit Summoning Holy State is not bad, not to mention that there is a paper covenant in the trade exchanges, but even so, the Spirit Summoning Holy State has not reached a deal with the emperor on the production method of the instrument.

The reason is very simple, only by strictly grasping the advanced technology in your own hands can you ensure that you will not be smashed open by your own equipment in the future.

The arcane technology of the Spirit Evoking Saint Kingdom is much more advanced than that of the Empire, and the quality of the defense and siege equipment is much higher than that of the Empire.

Unlike the dwarves' large-scale killing weapons made with pure mechanical technology, the instruments of the Spirit Summoning Sacred Kingdom usually use various spirit stones as power, and a variety of arcane devices as auxiliaries, which has a different kind of beauty. ap..

In short, they are elegant killers.

On the other hand, the structure of the empire's equipment is basically wood, and it is moved by human or animal power, or it cannot be moved at all. In terms of power, it is acceptable, after all, the equipment is a little bigger, and the power of throwing a boulder down will definitely not be bad, but it is far from having the power to dominate the battlefield like the dwarven equipment.

The equipment of the empire has not changed significantly for a long time, and it is not easy for the equipment experts of various academies and their abilities to research such a powerful device as the mocking dragon bed crossbow.

They have almost reached the limit of their current technological capabilities, and if they want to break through and innovate again, they need new technology.

As strong as Matilda, there is nothing she can do to update her equipment, so she is very excited when she hears Orfina's bold words.

Orfina wasn't joking.

The extremely curious Orfina visited the mechanical camp there with the status of an honorary saint when she was in the Holy Land of Spirits.

The captain of the team who took her on the tour was excited and proud to introduce the characteristics of each machine in great detail, and when Orfina asked him why he was so passionate, he replied:

"You're so beautiful! Moreover, machines are a man's romance!"

Orfina's eyes lit up, remembering the words, and wondering how Rogge would feel when faced with such a "man's romance".

The team leader only knows the characteristics of the machines and how to use them, as for how to produce them, this is not his specialty, and he can't reveal a thing or two to Orfina.

But it doesn't matter, Orfina has delved into the arcane on her own, and with enough materials and time, it is not difficult to reproduce the machines that seem to be powerful in her mind.

But now there is not enough time, most of the materials are scales, feathers, toenails and other parts on the body of the spirit beast, and it is okay to make weapons and protective gear, but it is not suitable to make equipment.

But it doesn't matter, the clever Orfina has a way.

Everyone came to the equipment camp, rows of stone throwers, ballistas, rushing cars, ladders, siege towers and other equipment were ready to go, and the soldiers were doing the final maintenance work.

The defense of the equipment battalion was very tight, and even if the Supreme Commander Filia and Grand Duke Matilda were present, the guards only took a second look, and still stood at their posts to monitor the camp in all directions.

"Nana, let's get started." Matilda couldn't wait.

The crowd followed in Ofina's footsteps and came to the front of the car first.

The Empire's mechanical technology is not as good as that of the Spirit Summoning Saint Kingdom, but it is several notches stronger than the Orc Alliance.

Almost all of the equipment of the Orc Alliance is made of goblins, and there is only one type of rushing car, and the structure is very simple, with a chassis, wheels, brackets, baffles, and battering rams.

There are three types of Imperial rushes.

The structure of the first type is similar to that of the Orc Alliance's rush; The second type is much wider, mainly relying on dragon horses, and people can stand up and down the baffle, and there is a certain ability to fight back in the face of the attack of the city wall; The third type is a large punch truck, which is about five meters high, which is about the same height as the city gates of some small cities.

Europe

Fina looked at the three types of carts, pointed to the second and said, "Who invented this? It's kind of stupid. The rush is mainly used to attack the city gate and city wall, and it is easy to be attacked. It's okay to bully people with this kind of thing, but don't use it to fight tough battles. It's too late to change everything to that one now!"

The one that Orfina said was the first type of rush, which was simple in structure but the most practical, and the rush of the Orc Alliance caused a lot of trouble for the Empire.

"Do as she says." Filia instructed the commander of the equipment battalion who followed her.

Orfina came up to the giant van and looked up and down for a while, and said, "This big guy is well designed, but it's too bulky, and movement is a big problem. Such a large device as the Spirit Summoning Saint Kingdom is equipped with a powerful power system, which is similar to the furnace thruster installed on the royal airship, but it consumes spirit stones."

"Alas, Lao Cha doesn't even know how stupid it is to put the furnace thruster on top of the siege equipment!"

The more mobile the chariot, the faster it can reach the enemy's walls, and the shorter the time it will be blocked, the less damage it will take.

The power of the giant rush is very great, and it can crash through the strong city wall, but how to get close to the city wall is a big problem.

Orcs can render the giant cart ineffective by simply using an archer or a ballista to target the horses pulling the cart or the dragon on land.

"Nana, do you have a solution to the problem of moving the giant rush?" Matilda asked.

Orfina paced back and forth twice and said, "I know how to do the power system, but there aren't so many spirit stones, and it's still that problem, there is not enough time."

"So there's another way."

The girl took out a pen and paper, quickly drew a set of drawings, and handed them to the commander of the equipment battalion.

"Can you read it? It's a very simple thing, change the wheels, make a set of tracks, and you can greatly improve your mobility."

The battalion commander took the drawings and read them carefully, and asked his question: "It's not that we haven't thought about making tracks, but it is difficult to lay on the battlefield, so I'm afraid it's useless."

"It's good to let the earth mage follow with you, and you can also use the earth wall technique to protect the rushing car at critical moments, and you can also deal with obstacles such as trenches."

"As for the making of the track...... It's definitely too late for the iron ones, so let's use the wood ones. There are so many soldiers in the army, and there are a few of them in one person, and there are quite a few qualified ones, which should be enough for the first two days. Let the logistics troops figure it out in the next few days."

"Do so, and let the whole army cooperate with the equipment battalion." Filia commanded briefly.

"Yes, I'll arrange it."

"Wait a minute." Orfina stopped the battalion commander, "Let's arrange it later."

The girl began to dig out the materials, and in a short time the various materials were piled up into a small mountain.

The battalion commander is a knowledgeable person, and he looked at the large number of rare materials and opened his mouth wide, "This ......"

"If you want me to say, it's better to use the most ordinary rushing car, after all, its duty is to break down the city gates."

Ofina quickly drew a drawing and handed it to the battalion commander: "Follow my method, add the materials to the punching truck. Remember to pack it according to the proportions I wrote, I've done experiments, and this one has the strongest defense."

"The scales of the dragon and the feathers of the feathers of the feathers of the feathers of the sun are not afraid of the flames; There are dragon scales of the Star Dragon and other wurms, and ordinary arrows will never be able to shoot through, and the bed crossbow can be defended. How, is it indestructible in such a modification?"

Orfina crossed her hands on her hips, leaving everyone with a handsome back.

"Yes, yes, yes!" Matilda was overjoyed and took the girl into her arms, "Then you said that you can make the trebuchet run and triple the power of the bed crossbow?"

Orfina "slipped out" into Matilda's arms and patted her beautiful little dress covertly, a little away from Matilda, who was dusty and bloody.

"Of course! Have I bragged?"

The group followed her to the area where the catapult and trebuchet were kept.

Orfina still observed for a while, and after making sure that her plan was correct

Directly took out the drawn drawings: "Sure enough, it's the same as I thought, just take it and change it."

She took out more than a dozen arcane devices and said, "These are the power systems I made, add them according to the drawings, and add them to a full-time driver. However, drivers have to be smart, and they must have cushions and spare wheels!"

The battalion commander was able to keep up with Ofina's thinking when she was renovating the rushing car, after all, he was a professional, and Ofina didn't use any high-end technology just now.

But as soon as the power system driven by this spirit stone was taken out, the battalion commander couldn't understand it, so he could only memorize all of Orfina's orders in his head, as for why he did it...... Execute first, then explore!

There are two drawings, one is for the transformation of the catapult and the other is for the transformation of the catapult.

The stone thrower is a heavy equipment, which is disassembled and carried to the battlefield site for assembly, and does not have the ability to move after assembly.

There was nothing Orfina could do to improve on this, but she designed a frame to properly place the components of the catapult, and put wheels on the frame.

This design greatly increases the assembly speed of the stone throwing machine and makes it more flexible when transferring, which is exactly what heavy equipment needs.

Considering that there were not many power systems, Orfina did not ration too heavy a catapult, and left it all to the catapult.

Everyone didn't understand it, but it felt very powerful.

Combined with the little cutie No. 2 gas bomb that Orfina just made, everyone knew that listening to her was over, and it was right.

"It's easy to use a bed crossbow! Do you know the pulley?"

The crowd shook their heads.

"How stupid!"

Everyone: "...... You're too smart."

"Add two wheels on both sides of the crossbow, and the strings are wound like this......

Orfina pulled out a modified hand crossbow and quickly demonstrated it, except for a few people like Rogge and Filia, whose brains were spinning fast, everyone else only thought she was playing with the rope.

"By the way, the crossbow body chords can be updated with materials, and the power can be increased by about three times, and there is no need to change the main structure of the bed crossbow. Isn't it easy?"

Everyone nodded their heads, "Ah, yes, yes."

"Oh, I know you're stupid, you really can't update the materials directly, and there are improvements. Anyway, I'll use up all those materials, so don't waste them at all! Battalion commander, do you hear that?"

"Yes, sir!"

"Sir...... What kind of pulley, do you have any drawings?"

"Why?" Orfina gave the last drawing, and her face suddenly became serious, "Keep the drawing, and the leaker will cut off his head!"

"Yes!"

"Poof~" Orfina laughed, "It's all trivial. That...... A total of 100,000 gold coins, the battalion commander has to keep a good account, and I have to ask Lao for it when the war is over!"

The battalion commander said, "I think 100,000 is less. What do you think, Your Excellency, Commander-in-Chief?"

"Remember 150,000." Filia's face did not change color.

"Two hundred thousand, Lao Cha has money." Matilda smiled and doubled Offhaena.

When the money arrived, Orfina was very happy, and by the way, she told the battalion commander: "Okay, you can go and give orders." Remember, my drawings are very precise and follow the drawings exactly, and you can't make mistakes."

"Yes." The battalion commander turned to leave, but suddenly stopped, and asked again, "Who are you?"

"Huh." Orfina turned her back to everyone again, grabbed the hem of her skirt and shook it gently:

"Call me 'Nana, the god of light.'"
