I've seen the map. Although I can't read the labeled symbols, at least I understood the words and some of the pictograms. There is a mountain range between Zdis and Lahs, and this mountain range spreads to the vicinity of Kroni City and basically becomes a mountain range, which is not much of an obstacle for our demon soldiers to march from Kroni City to Lahs City.
For the sake of memory and description, I saw the map according to the geographic knowledge on Earth.
The Earl River flows from the sea in the southwest of our Demon Kingdom to the east of Lahs City, which means that the Earl River crosses two countries. The north of the Earl River is in the Human Kingdom and the south is in the Demon Kingdom. The whole river runs southwest to northeast.
That mountain range that straddles between the Zdis City and the Lahs City is named the Valan Mountain Range, which is closer to the Lahs City.
The master drove us early with Cross to a mountain near Lahs City. And we are now on the top of the mountain. The master opened my sixth level of ability, so I can see the demon army that is coming to Lahs City.
By the way, not only can I see clearly, if I put more mental energy to observe more carefully, I can also see how many eyebrows of a certain soldier from the distant demon army, and even hear the people talking in the Lahs City. And I can hear that their talking is not a cloud of noise, and I am able to distinguish each of the words they spoken.
This is the legendary ability that I can see and hear something from the distance and this ability is controllable.
But I am still more concerned about the situation of the demon army.
The vast demon army was like a black dragon stepping through the dense mountain forest, with black-armored soldiers charging at the front, followed by an army of artillery carts, a long-distance magic army, an army of bows and arrows, and cavalries.
The soldiers at the head of the various armies carried the banner of the Demon Kingdom, and the wind tugged the black army banner in a confident and powerful manner.
Turning my head to look at the Lahs City, the gates were closed, and a strong wind swept by, blowing up the yellow sand on the bare ground in front of the gates. The tall gray-brown walls were painted with the traces of black marks of the battlefire, and stood soldiers who were in ready and dressed in brown armor on them.
The first time I came to observe the war, I saw such a grand scene. My fear in my heart has long been overshadowed by a sense of curiosity and excitement .
The trumpet of the war was deafening and resounding like thunder, and the infantries of the demon army roared and charged like mad lions, and they were coming to the Lahs City.
Even though the prelude to the war made my blood boil, I didn't have a desire to fight for some reason.
Sure enough, it was right for my master to bring me here to witness the battle. If I go into battle in this state, I'm no different from a loser.
The human soldiers stationed on the Lahs City, the bowmen pulled up their longbows, the magicians began to chant. The bowstring vibrated the air, the bows and arrows whistled out, many magic arrays appeared in front of the magicians one by one. There was a red light attached to the bows and arrows, and then the tip of the bows and arrows came out of the fire, and far exceeded the range of ordinary bows and arrows, straight to the distant army of the demons.
However, an ice-blue light shield lit up on top of the demon army, and the bows and arrows hit the light shield. Then the arrows’ fire went out, and the bows and arrows fell down weakly like the fallen dead branches.
The long army of the demons was as unstoppable as a lion out of control, and all long-distance attacks by human soldiers stationed on the Lahs City did not work.
Until the demon's army was almost under the city, the resounding trumpet showed the soldiers of the demons had the great desire to fight.
Suddenly the human soldiers stopped releasing offensive magic, bows and arrows at the demon army, instead they shot arrows at the city, and the magicians continued to attach magic to the bows and arrows. So the bows and arrows fell to the ground, and the ground without any combustible material started to burn with fire.
It seemed that the humans wanted to spread a sea of fire to stop the demon army from advancing.
The demon army stopped in front of the sea of the fire and the infantry army shot blue magic beams at the sea of fire, which the fire had a tendency to fade away.
The shells that shot from the artillery carts in the deafening roar shot past in a straight line trajectory in a fast speed.
Finally the shells blasted into the walls, but surprisingly the wall did not have a crack, only leaving a hedgehog-shaped scorched black traces.
With the sixth level of ability, I could see everything in my eyes and my ears could distinguish many sounds. Also because of the sixth level of ability, I could probably tell the approximate speed of the shells, which reached over six hundred meters per second.
I found that the shells did not conform to the kinetic energy theorem because the speed of the shells shot from the artillery carts was surprisingly getting faster and faster.
But with a closer look it revealed that there was a faint red light in the remnants of the shells flying out at high speed. I originally thought it was spark, but it was not. It was a kind of magic that would propel the shells forward. The faster the speed of the shells was, the more powerful this magic would be. So the acceleration of the shells was getting faster and faster, which in turn made the speed of the shells faster and faster.
But the otherworld can't be explained by science. I'd rather not think this problem.
But there was a mathematical problem, like the problem of water intake and drainage in mathematics.
The sea of fire was about 1000 square meters. The extinguishing speed of the demon army was about 19 square meters per second. The fire setting speed of the human army was about 10 square meters per second. The duration of the entire demons' extinguishing ability was about ten minutes. The cooldown was about three minutes. However, the duration of the humans' overall extinguishing ability was about five minutes. So was the cooldown of humans about one minute? So how long will it take for the demon army to put out the sea of the fire?
No. Now human magician reinforcements have been added, so the humans can set fires faster.
I'm too lazy so I can’t do any more calculations. Of course, the cooldown didn't really stop and I just used some people as samples and observed their casting time and rest time. And then I calculated the average as an overall average. But if I really wanted to calculate the time of cooldown carefully, I could not finish counting until the end of the war.
The sea of fire was finally extinguished and the infantry started charging towards the gates.
