Summoning the Spirit, because it has just received an upgrade in equipment, the Spirit can already have the ability to call Belling across the plane at any time. Of course, interdimensional communication requires a lot of giant power from Ryuichi, but this is nothing compared to Ryuichi's possible gains.

Long Yitong Guò Ling Ling told Sù Bei Ling that he had arrived in a safe place, and he was very eager to get help from the Crystal Demon Plane.

It didn't take long for Belling to reply, and she told Sù Ryuichi that because of the limitations of the plane, the crystal demon had no way to directly generate a body in this world to help Ryuichi fight, especially since there was also the sun in this world that the crystal demons didn't like. However, after a series of research, the scientists of the Crystal Demon Clan have produced a batch of Crystal Demon Light Cannons, which use a general protocol and can be placed on any equipment that is powered by the crystal nucleus, and the power of the light cannon fired is related to the output power of the crystal nucleus.

Then, through Guò's reverse research on the catalytic crystal, the scientists of the Crystal Demon Clan obtained a magic circle, which can amplify the output energy of the crystal nucleus in a few subtle times, which will greatly increase the actual output power of the light cannon. Because of the interference, the crystal demons could not use this magic circle, but the humans were not affected. Combining the two, the Crystal Demon scientists have developed a powerful light cannon. The first batch of 100 units had already been built, and Belling asked Ryuichi if he really needed it.

Long Yi was so moved that he was about to cry, and he immediately said that he wanted as much as he wanted! However, Long Yi also euphemistically said that he seemed to have something that could be exchanged as a reward.

It didn't take long. Belling responded to Long Yi with a smile, the harvest that the catalytic crystal crystal brought to the crystal demon clan was more than ten million times that of these light cannons. It's just that these light cannons are nothing at all for the crystal demons, and it is only a matter of minutes to make these things.

Although Ryuichi doesn't really understand the way of life of the crystal demons, it sounds like the crystal demons are best at making things in batches. Because when Ryuichi asked how long it would take to provide the first shipment, Princess Belling told Sù Ryuichi. 10,000 units can be manufactured in less than a month!

Ryuichi went crazy at the time.

Ryuichi originally planned to ask the scientists of the Crystal Demon to help improve the energy-powered crystal nucleus of the battle armor, but after Belling listened to Ryuichi's description, Belling told Ryuichi. The improved energy core of the White Dragon Empire's design of the Undercity is already a structure that maximizes the energy of the crystal nucleus, and there is almost no room for improvement.

Ryuichi and Princess Belling exchanged a lot, until Ryuichi felt that his giant power was almost impossible to resist, and then he stopped. Princess Belling sued her. The Crystal Demon Clan is in a big battle with the mad demon at this time. Looking at the progress, it may not take long to regain the Mad Demon Planet. When the time comes, it may be easier for Ryuichi to go to Princess Belling. Long Yi was looking forward to it, but in Long Yi's opinion, it might not be long before he would enter the upper plane.

Ending the call with the Crystal Demon Princess, Long Yi rushed to the Royal Academy of Science without stopping.

The tractor project is of great concern to Long Yi, if the war cannot become a hammer deal. Then in the end the absolute war will go to the protracted war. And the most important thing in a protracted war is supplies. Without steel, man can live. But there was no food. People are finished. The White Dragon Empire is an empire with an extremely strong commercial atmosphere, once there is no food, you let that group of people run away and farm their own land?

There are no doors!

Therefore, when the delivery time of the light cannon was agreed, Long Yi immediately rushed to the Royal Academy of Sciences. In the underground proving ground, a tractor with a striking and modern appearance is quietly parked there.

But that's just a shell.

Next to the tractor casing, is the heart of the tractor, which is the crystal nucleus drive engine that drives the tractor.

The crystal nucleus engine is powered by a crystal nucleus and connected by a guò array to drive a series of complex gear sets. Of course, there is no precision processing equipment in this world, so there is no need to think about the gearbox at all. Fortunately, the crystal core engine has very good low-speed torque.

There is no rubber in this world, so Ryuichi designed the tractor as a tracked structure. Rough tracks and heavy load-bearing wheels can still be made by dwarves.

Long Yi glanced at the tractor and counted it silently in his heart.

"One, two, three, four, five...... Well, five pairs of weight-bearing wheels, perfect. ”

When Magdeburg and Angel heard that Ryuichi was coming, the two of them rushed out of the next lounge in disheveled clothes.

"Two great gods, am I disturbing your good deeds?" asked Ryuichi with a smile.

"No more nonsense, come and see!I've already sent someone to inform the dwarves!" Magdeburg didn't have the heart to comprehend the subtext of the dragon's language, and pulled the dragon to the crystal nucleus engine.

"Since that day, Dean Angid and I have mobilized three elite teams to tackle the mechanical structure you described, and finally got us to solve the problem of engine power transmission. Inspired by the airship's circle, we set up an inspired circle and bombarded the same circle diagonally with the deflected force by 45 degrees, so that we used two sets of crystal nucleus energy sources, one fixed, one mounted on the axis, and the other rotated. By adjusting the excitation range of the crystal nucleus of the fixed group, you can adjust the power of the output!"

As he spoke, Anjid handed Long Yi a chart on the side, which was a series of graphs, including rotational speed, input mana range, energy loss, and so on.

"The optimum range is between 800 and 3,000 rpm, so we plan to lock the revs in this area. Anjid explained on the side.

When the dwarven elder Morton came to the test site, Magdeburg and Anjid were standing on both sides of the dragon on the left and right, constantly explaining the principles of some places, and at the same time, the materials in their hands were handed over one by one.

In the end, everyone stopped talking and waited quietly for Ryuichi to answer.

Long Yi carefully looked at each piece of paper, and looked at the crystal nucleus engine carefully. At this time, Magdeburg is so good that Anjid doesn't even have an atmosphere. For fear that Long Yi would say something wrong, they had already checked it countless times for this.

"Actually...... At the moment there are no more problems. Of course, we may need to pay attention to water and dust protection, after all, this thing has to work in harsh environments. But it's not a problem, and it can be solved by adding a shell later, but what about the temperature?"

"Temperature?" said Magdeburg and Anjid, looking at each other.

"Yes, any mechanical movement generates heat, and this crystal-nucleated engine uses such a large density of energy and carries a load. The calories are definitely high. Long Yi said.

"This ...... We didn't think about it. Anjid's face was flushed, he didn't even notice such an important thing!

"Forget it, it's not a big deal. Let's install and test it first!"

Ryuyi turned his head and smiled at Morton.

"It's okay, it's okay, we're not in a hurry, the core power is very important!" Morton has a dwarven instinctive love for metal and machinery. He especially likes to listen to Ryuichi talk about this knowledge. I really never get tired of hearing it.

"Let's start with this organism. ”

Long Yi walked to the body of the tractor, the structure of this tractor is far less complicated than Long Yi's previous life, and it is difficult to completely restore the design of that world with Long Yi's knowledge, but the simple structure does not mean that it is not easy to use.

"Yes, no problem. Come on, let's install it. First, install the energy core on the gearbox. ”

Long Yi didn't have the ability to design a gearbox, there was only one gearbox to increase the torque, and the speed was completely controlled by the operator.

The gearbox consists of a series of coarse gears. After the two were combined, Long Yi directly carried it with both hands. Slowly installed on the tractor's floor, locked, installed operating seats.

Then, it's time for the trial.

The fighting spirit played a role in the motivating circle, and with the click of the mechanical gears, the tractor really moved slowly!

After a moment of silence, deafening cheers rang out from the entire test site!

The benefits of simple structure are reflected here, because the structure is simple, so as long as every link is completely in accordance with the design and manufacturing, the original design purpose will be achieved.

Long Yikong turned around the tractor a few times, touched the core and the reduction gearbox, and the temperature was okay.

"Traction test!"

As soon as the dragon shouted, several people from the mechanical courtyard came up and hooked the hook at the tail of the tractor to an extremely thick chain. The other end of the chain is attached to a large device.

"This is our own traction test set. Anjide said proudly to Long Yi.

"Don't get broken. Long Yi said.

"Don't worry, no! the maximum tensile strength of my thing is three tons!" Anjid was full of confidence.

As soon as Long Yi was injected with fighting energy, the core suddenly let out a dull humming sound, and the speed reduction box made a clicking sound. But Morton is not worried, the things made by the dwarves may not look good, but they must be strong!

Suddenly, only a muffled bang was heard, and the chain holding the tractor was broken!

Everyone only felt their eyes twitch, and the tensile force of this chain was a ton!

"Change the chains!"

The chains were replaced, the test continued, and when Ryuichi fully released the power of the core, the tensile gauge was already close to its limit.

"The core energy output is a small half, the pulling force is about one ton, and the full output can be about three tons, which is not bad. "The dragon nodded a little.

Anjid wiped the sweat from his head, he even thought his rally meter was going to break!

"Hang the load!"

Long Yi shouted.

A series of huge iron mounds worn together have already been prepared on the side of the test site.

Long Yi immediately drove the tractor around the test site with an iron lump. As a result, after less than five laps, a spark suddenly burst out of the core, and Long Yi immediately jumped out of the tractor, but there was no explosion.

After waiting for a while, everyone came over. However, it was found that the shafts at both ends of the core had been bent due to high temperatures, so as the power output and the two discs could not be aligned, and the guide energy could not be conducted.

"Alright, now let's get the cooling out of the way. (To be continued......)
