The three-year study abroad life is not long, but it is not short, and when you are immersed in life, it passes away quietly.

Although it may seem like everything is calm and quiet in the past three years, a lot has happened in the world.

Let's start by looking at the front line between Middle-earth and the Cang Dynasty.

After three years of cultivation, the Cang Dynasty once again formed a large army, with a huge number of firearms and firearms, and even a large number of steam armored knights in the newly formed army, made by the steam armor craftsmen of the original Duchy of Turin.

Over the years, they have stepped up their catch-up with various weapons and technologies to strengthen the armament of this army.

The Cang Dynasty army also built a large number of fortifications on the border between the two sides, and criss-crossed trenches linked the fortress groups one after another, forming a steel-like defensive line. Captured fortress guns and various types of artillery were also placed on the defensive line, and the construction of artillery and shells continued, and ammunition and artillery factories were also built in an orderly manner.

And they are carrying out their technological reforms, using the industrial base of the Duchy of Turin itself to carry out a great industrial revolution. The Cang Dynasty, which is becoming stronger and stronger, is a huge threat.

In order to deal with the threat of the Cang Dynasty, the Middle-earth coalition army also did not relax in the past three years, and a large number of battle-oriented trenches conducive to the offensive were built on the front-line positions, a large number of artillery positions were also arranged on the border, and countless supplies came here from various places in Middle-earth.

The city of Frankfork was transformed into a military base for the forward command, and radio communications equipment and various logistical support were being prepared. A large number of troops were sent to the front, and more troops began to train in various places and were ready to go to the battlefield as reserves.

The countries of Middle-earth had begun a limited mobilization for the war, with some retired soldiers being re-drafted and some factories beginning to change production lines. Some women were mobilized to work as paramedics.

The Rhine Kingdom is naturally the country that is most concerned about the movement of the Cang Dynasty, and the current king even does not hesitate to give up some important powers to win over some entrepreneurs in the country and another royal bloodline that he drove away, just to be able to form a strong army.

On the side of the Holy Kingdom, for the goal of the Eastern Crusade, they also began to gradually focus their attention on the war with the Cang Dynasty. More Heavenly Punisers and some secret weapons are being developed and mass-produced.

The Sino-Turkish alliance held several congresses and agreed to the joint management of the railway connection throughout Middle-earth, as well as the formation of a larger coalition army.

As both sides continue to add chips on the border of Frankfork, the clouds of war seem to loom over the place again.

Everyone knows that if there is to be a return to complete peace, then a war, a war that can completely solve everything, must be fought, and this is why both sides are desperately trying to increase their chips.

No one wants to lose this war and be on the side that suffers humiliation.

If Middle-earth loses, it will be a great blow to the self-confidence of the people, and all subsequent strategic plans may be in vain, and more importantly, the prestige of the Holy Kingdom will be hit.

If the Cang Dynasty loses, then it will lose its last foothold, and the entire country will die out as a result.

Then let's look at the Esoteric Institute.

During these three years, with Kirsten's departure, the Institute returned to Dr. Heigl's hands.

For the coming war, the conquest agencies are stepping up the development of mass production of the Heavenly Punisher, while the Institute of Esoteric Research, under the leadership of Hagel, is researching another weapon of war.

It was a weapon that could be used to fight in the complex terrain of mountains and hills, and was designed to meet the needs of the Eastern Crusade to attack the fortresses built on the mountains in the east.

In the war against the Cang Dynasty, there will be them as well.

At this time, Dr. Heigl took Ludwig on the tram and crossed a secret passage to an underground cave that was smaller than the crown of Gaia.

Lying here lies a giant complex with a huge ventilation system running at high speed, sending exhaust fumes to the ground; Countless lights make it look like daylight. It's just that the Gaia Holy Crown, where the Institute of Secret Research is located, still has a special power generation device to maintain a huge power consumption, but I don't know what kind of power generation device is relied on here to maintain the power consumption here.

If you rely on a steam power station to sustain yourself, you can't imagine how much red mercury you need to consume in a second.

Ludwig and Dr. Heiger went to a high-level stand.

"This is my secret weapon, a steel behemoth powered by the latest internal combustion engine technology, the master of future wars."

Rows of armored, steel behemoths with six mechanical legs stood silently in front of the complex. Each machine has two main cannons, and from there, the barrels speak of their deadly and deathly chills.

Their sheer size and devastating firepower make them heavier than four standard steam vehicles, and the use of the latest manganese alloy gives them armor that is stronger than four standard steam vehicles.

Such monsters are naturally born for war.

"Allow me to introduce you to my latest creation, the Multi-Legged Siege Machine, Leviathan I!" Dr. Heigl stretched out his arms and said to Ludwig.

Yes, the Institute has been working on internal combustion engine technology recently. Although their strength is not in this area, under Dr. Heiger's leadership, they also have their own achievements in the area of internal combustion engines

This is because the apostles knew how difficult it was to use a steam engine to drive a humanoid machine without the exotic substance of red mercury, especially since the cost of red mercury was higher than that of rock oil.

In the long run, until the substance of red mercury is thoroughly understood, the use of rock oil is the general trend of the future.

The Heavenly Punisher was an experiment of the apostles, and when they discovered that even the application of the internal combustion engine required the manufacture of machinery more than ten meters high to accommodate the power plant and maintain the performance of a war machine, they understood that the current research on war weapons in the whole of Middle-earth was somewhat extreme.

As a result, the non-human mechanical weapons began to be carried out quietly. However, in order to deceive other countries, the Holy Kingdom still regards the Steam Mecha Knight as the main force of the country. But in the shadows, research into new weapons of war is quietly underway. Leviathan I is one such product.

This is a new type of weapon, and the personnel of the Institute of Secret Studies have secretly trained a group of fighters who can fly behemoths with Ludwig's men in the military department.

However, it is clear that the resourceful Ludwig did not notice this, so he is only now surprised.

You must know that there is a clear gap between the development of a weapon and the mass production of a weapon, not to mention that these weapons can be tested on the battlefield.

He knew that the Apostolic Council was planning to attack the Cang Dynasty, and while solving this scourge around him, he could also open the way to the East. So, these weapons are going to be used in the largest battle in a century.

Someone like Dr. Heigl was so proud of this weapon that it wouldn't disappoint Ludwig.

This will greatly expand his political and military power and suppress his enemies.

At this time, a large number of personnel have begun to debug these mechanical behemoths, and a huge number of transport trains have begun to prepare for the shipment of these war machines. They are about to go to the front lines of war, ready to destroy everything in sight.

Finally, we looked at Kimchi and Kirsten, who were sitting on the school bus.

"You're a hard prosthetic." I grumbled again as I buried my head in helping Kirsten apply alchemy lubricant.

In the past three years, I have gone from being curious for the first time to being bored now. Yes, Kirsten had to get a prosthetic replacement almost every year for those three years, and asked me to help her every time.

Especially every time you ask me to come to the alchemy lubricant, you just treat me like a slave, okay!

"No way, the prosthetic leg I designed is so exquisite. Otherwise, how can it really be like a hand? Kirsten waved his hand and said in a slightly helpless and proud tone.

“。。。” I had nothing to say but resignation. Anyway, it's been three years since I did it, and it's not bad this time.

But it has to be said that the prosthetic limb designed by Kirsten is very ingenious, and through the precise mechanical structure and some neural link technology of the Institute of Secret Research, it can be made like a real arm.

"Alright." I wiped the sweat that wasn't there.

"I'm getting more and more proficient, and it's up to you in the future." Kirsten moved his prosthetic leg and said with satisfaction.

"Don't look for me again when you go back! I am not your servant. ”

"Okay, okay, you've said it a few times, and I don't feel like my mouth is calloused, I feel like my ears are going to have muscle memory."

The bus slowly stopped and we walked down.

Since Kirsten was three years older than me, he was almost the same height as me. I carried both of our handbags, and her reason was that she was disabled and should be taken care of.

Today is a final exam, which requires several students to work together as a team to complete a practical internal combustion engine application machine.

Naturally, Kirsten and I were in a group, and there were only two of us in our group. After all, neither Kirsten nor I are very good at communicating with other students.

Our classroom is taught by Professor Karen, one of the founders of the internal combustion engine. A native of the Duchy of Gaul, he now resides in the Duchy of Lorraine, and occasionally gives a few lectures to the students of the Collège of Gaul at the invitation of the Collège of Gaul.

As a native Gaul, he was a humorous person, often joking with his students, and his classes were very interesting, and he was loved by many students.

However, he has high requirements for the quality of his homework and exams, and he should not want him to let him go.

My work with Kirsten is an engine. According to the engine of the steam airship developed by the Holy Country, the engine has been modified to a certain extent, and the power source has been changed from a steam engine to an internal combustion engine.

While reducing the size, it also increased its output power, which can basically ensure that one engine is enough to complete the liftoff of a small aircraft.

Of course, this is all theoretical, and although the results are amazing and praised by Professor Karen, it is still a long way off to put it into full use.

No one bothered to remember this thing that could change the future, including me and Kirsten. After all, the steam airship can already carry dozens of people into the air and is a large flying machine.

Just like a large steamship has been developed, who would put a lot of effort into developing a small steam engine to make a small wooden ship steam powered?

Even the inventors of the internal combustion engine themselves were somewhat skeptical that the internal combustion engine could really replace the steam engine.

After all, a general steam engine only needs coal mines, while internal combustion engines need to extract rock oil and purify it to a certain extent.

After completing our final exams, Kirsten and I started our old business, taking out chess and going on a killing spree.

So before I knew it, the final exam was over.

In the evening there will be a big dance party. For various reasons, Kirsten had not yet attended the ball, so he took me with him.
