"What is going on?" I thought to myself, as I lay in bed enjoying my leisurely slumber, but now I'm wearing heavy armor and my brain can't seem to wrap around the situation. Kidnapping? I immediately denied this possibility. As I looked at the strange plants on both sides of the winding mountain road, I realized that although I am not a botanist, these leaves are clearly not ones that could grow in reality. If I were in a dark room and someone threatened me directly, forcing me to make a phone call and demand one or two million yuan from my family, I would still be able to confirm that this is a kidnapping.

But now, after walking for seven hours and covering fifteen kilometers, I confirmed that I am in a different world, and in the midst of an army in this world. My body is covered in a suit of tightly fitted steel plate armor, protecting my vital organs. My knees are supported by springs and wear-resistant steel knee pads. The shiny metal helmet sits on my head, and my initial estimate of the weight of this clattering protective gear is at least twenty kilograms. Of course, this does not include the flintlock rifle in my hand, which is about nineteen millimeters in caliber.

So far, I have been able to endure due to my relatively thick thighs. Although my feet have blistered heavily, I still strictly abide by the discipline of this unit and carefully serve as a soldier in this otherworld. With a steel gun in my hand and a full set of armor, it's not a reason to be arrogant after crossing over. Because I'm not entirely clear about the combat mode of the military in this world, but as long as it's a military, it's strict with discipline. From the strict marching of the army, it can be seen that I must be honest in the Legion of the Fanasa Expedition. Being a deserter or anything like that is purely suicidal in this 3,000-strong army.

The loud clanging sounds drew my attention as a gigantic, fifteen-meter-tall robot made of seemingly metallic bars passed by me. From the strange text written on its combat regulations, I could tell that this was an electrically-powered robot. I put aside my confusion as to how I could understand these characters that I had never learned before. The tactics manual had mentioned that in dealing with these large robots, troops should form a slanted line and use incendiary bullets, as these machines relied on dense firepower.

As for what to do if one of these mechanical beasts charged at me? The manual stated, "We are the glorious Miaana Royal Riflemen, fighting for the honor of our kingdom. Maintain formation and open fire." I glanced at the giant robot that had just passed by me and its electric sparks jumping off its arms, which were twice as thick as my waist. I swallowed my saliva. The kingdom's honor and glory were now classified in the same category as pyramid schemes, in my opinion.

I've criticized the technology of this world countless times. They have electricity and can use natural information storage rocks to create combat-ready artificial intelligence robots. They have artillery, but all of them are steam-driven vehicles with tracks and boilers. I've heard of steam tanks and the like, but I've yet to see them. However, the basic infantry soldiers wear bulletproof armor and are inspired by classical militarism, engaging in hand-to-hand combat with heavy front-loading rifles.

This is definitely not Earth's technology tree.

The only thing that gives me some peace of mind in this unfamiliar and daunting world is that I am not the only unlucky kid forced to be a soldier in this world. When I arrived in this world, I was promoted to a platoon leader of 80 soldiers. I had no idea how to lead troops, so I simply followed the rigid rules and regulations. As for whether this army is reasonable or not, I just waited and observed.

But three days ago, a fellow platoon leader of the same rank as me expressed his military views and suggested that we should discard our heavy armor and go into battle lightly armed with guns. However, he was demoted to a private by General Calini, who claimed that the army didn't need someone who was pampered and talked big.

From the suppressed talent's face and tone, I could tell that he was from the same world as me. He may have only been a high school student, but he made the mistake of trying to apply the system from our original world to this one. Although I cannot confirm the effectiveness of light infantry wearing armor in this world's army, I am certain that the atmospheric density of this world is different from that of Earth. The different atmospheric pressure means many things are different, such as oxygen content. In the era when giant arthropods flourished on Earth, dragonflies were one meter long and a millipede was the size of a car. At that time, the oxygen content on Earth exceeded 30% of the atmosphere, creating a world of giant insects.

The story has been illicitly taken; should you find it on Amazon, report the infringement.

However, now I am sure that the atmospheric pressure in this world is not right. When I first arrived, the surrounding atmospheric pressure felt like being submerged five or six meters deep in water. In this high-pressure environment, the worst feeling is several days of insomnia and difficulty breathing out. As for the benefits, walking for such a long time without getting out of breath is one of them, but the side effect is that the muscles in my thighs ache from walking.

The feeling of not being able to sleep well makes me want to curse at anyone, but unfortunately, I cannot vent my frustration because of the uncertain future. The situation of the high school student who couldn't help but persuade me was just the result of being pushed to the limit in this environment for a person from a peaceful era.

However, it was this high school student who made many other time travelers who were previously alone realize the existence of others like them. That night, six East Asians, three Black people, and seven White people, all of whom had assumed they were natives of this world, gathered around a campfire and discovered each other's presence. "Hey, there are quite a few of us," they thought.

The flames of the bonfire rose, and among the sixteen people gathered around it, including me and the young student who had been dismissed, were several junior military officers. One bearded White man pulled out a tactical manual, and as several people recognized the gesture, they also pulled out their own tactical manuals to discuss team tactics. I was a bit slower to react, but after thinking for a moment, I understood. It was suspicious for a group of junior officers to gather together without a clear reason or purpose.

Of course, it was already suspicious for a group of low-ranking military officials to gather together in the first place, but this just gave bystanders a plausible reason. After all, every time traveler's replacement identity in the kingdom was that of a minor noble.

"Formation line, with twenty-seven variations based on terrain..." After reading a long passage, the bearded White man calmly said, "Andrew, 2016 Olympics in London." The Black man next to him said, "Jace, Somalia." One by one, the time travelers quietly reported their names.

But as the other five East Asians reported their names, my good mood at encountering fellow time travelers in another world was shattered. Daichi Inoue, a man in his thirties, from the 2008 Osaka Olympics. Chiharu Takeshita, a middle schooler with chuunibyou syndrome from Tokyo. Ryouko Nakamura, a sixteen-year-old female student from Kanagawa. Chiharu Niizuma, a twenty-year-old man from Kobe. When these obviously Japanese names were reported, my eyes went blank in shock. I looked at the last person, hoping for a teammate.

Li Zuncheng, from Seoul.

"More than half of all East Asians in the world are Chinese. Why did they send me here?" I used various dialects to vent my frustration and complaints about the being who had sent me to this world.

But under the scrutiny of everyone's gaze, he said expressionlessly, "Li Di, China." The other few Asians also frowned, and I hesitated for a moment, then leaned towards my side. "Korea is better than Japan!" Four out of six Asians were Japanese, and I didn't think I had the ability to beat three Japanese and win a Japanese girl. So if I allied with Japan, I would have to compromise and express my pro-Japanese stance. Well, I don't think I can pretend that. So the only option left is to be friendly with Korea.

I smiled friendly at Li Cuncheng. But in the corner of my eye, I saw a hint of disdain in Andrew's eyes. I knew what this British man was looking down on. Isn't it just an internal conflict between Asians? If you throw a few Chinese people in according to the true mathematical probability, how could this situation occur?

Andrew said lightly, "It seems that we are all victims of this mysterious incident. In the current situation, I don't want us to have any internal conflicts."

After saying this, Andrew swept everyone with his eyes. A few white people nodded, and a young Greek man shrugged and said, "I just want to go home. The rest is up to you." Andrew looked at a few black people, and they looked at each other and silently nodded.

Then, the elder among the Japanese, Ono Inoue, spoke humbly in Japanese, "You make sense. We will follow your arrangements."

Looking at Andrew's seemingly sincere and persuasive eyes, I said, "I want to live, just like you all. This is the basis for our cooperation, but trust cannot be established in a day."

Andrew looked at me and said, "Chinese, it's not time for internal conflict."

I shook my head and said, "I won't harm anyone, but I will defend myself." Upon hearing my typical Chinese diplomatic response, Andrew slightly frowned but seemed satisfied.

Li Cuncheng glanced at a few Japanese people and said, "I agree to cooperate, but if someone deliberately wants to harm me, I will retaliate at all costs."

After all opinions were discussed, Andrew said, "How do you all see this world?"

I wanted to speak, but Li Cuncheng spoke first, "This world is like a game I used to play called Rise of Nations Continuation."

As soon as he finished speaking, a bright light enveloped everyone. We stood up in surprise and slapped the light, but found that the people around us seemed to have not noticed the situation here. The whole team ignored the appearance of the light shield and the surprised reaction of the people inside.

"Welcome to the battlefield of time and space." A mocking voice appeared in the light shield.
