In the known world, there are four typical climates. From the middle line of the world to the south to the north: tropical, subtropical, temperate, and cold (i.e., polar climate).

The tropical climate is relatively stable with the polar climate, which is slightly affected except for about 2 months a year, and the rest of the year is the same ice and snow and scorching heat.

The temperate climate is the most suitable for human beings, and the year is divided into four distinct seasons, spring, summer, autumn and winter, completely different weather.

The subtropical climate is the cleanest, with two seasons a year: hot and rainy summers and dry, dry winters. A rain in the second half of the year, followed by a drought and another half a year.

-- "Continental Climate" Chapter 39 Three-Front War Magic Calendar 6 years, the offensive and defensive transformation of the continental war has always developed at a relatively rapid speed.

After the last offensive and defensive battle of Hamburg ended with the retreat of Dahaino's legion, the base camp temporarily abandoned its plan for the Messisian Mountains - even if Marshal Dahaino still had the idea of continuing to fight, the headquarters would have ordered the withdrawal from this asymmetrical and serious war of attrition.

In this icy and snowy land, to maintain a normal supply of 10,000 people, it is necessary to use at least 20,000 migrant workers to transport it, and at least 5,000 regular troops to escort it. If it is changed to summer, the materials consumed during transportation will be reduced by at least 65%. Supporting such a war would undoubtedly add insult to the supply system of the Western Emperor Group, which was already overstretched.

Of course, the staff base camp is not idle, the best staff officers of the pan-continent set their sights on the largest forest in the hinterland of the continent, and on January 20, the sixth year of the magic calendar, the base camp customized a new combat target: the boundary forest war zone. In the past year or so, this small theater ranked sixth in strength among the seven major theaters, like a tenacious iron thorn, jumped out from time to time to remind the Holy See and the Burmese Empire to pay attention to his existence.

Each of the seven major theaters of the empire has its own superior troops, the strongest in the Northern Federation is the infantry, especially the glacier infantry, the most powerful navy in the ice harbor theater, gathering 80% of the armed fleet of the empire, the most famous ironclad heavy knight unit in the Gyeonggi theater, the light knights in the Tongyunguan theater, the pikemen in the Lion River theater, the only swamp infantry in the empires in the Sanggan River theater, and the strongest jungle knights in the seven theaters in the Jielin theater.

The supposedly elite Jungle Knight mounts are all war horses, which may be a misnomer, a cross of horses, not very tall, and very thin and dry.

The Jungle Knight never participated in the imperial military parade, in the history of the empire, the third general of the Jielin Theater of Operations, Qi Mingwu, once took his most proud troops to the imperial capital to restore his life, and ran headlong into the three commanders of the Tongyunguan Theater, the Northern Federal Theater, and the Gyeonggi Theater, so there was the following dialogue.

"Hey, old Qi, you've been living too hard these days, why are your knights all riding donkeys back to their posts?"

"How do you say this, where is there a donkey? I obviously saw a group of black long-haired goats, not to mention, this breed is really good, I have never seen such a big goat, each of which I have to see 100 catties, this is a new breed of Huayu Plain. General Qi, when will you send me some? We can't eat anything in the Northern Federation, and after you black goats arrive, we can eat meat every day. "Is this shabu mutton or shabu shabu...... I don't know.

"Old Qi, when will the Jielin War Zone be equipped with police dogs? You soldiers are too disagreeable, why the fuck are riding on dogs. I'm going to the Small Animal Protection Society to respond to this serious question!"

Ridicule is ridicule, in that debriefing, the angry General Qi Mingwu specially arranged an internal exercise, the protagonist is this group of soldiers known as riding donkeys, riding goats, and riding dogs, the jungle knights easily passed through the 50-mile-wide forest on the north side of Scambrai in a battle formation within an hour, and then faced with the impact of the superior forces of the Colorful Dragon Knights, the jungle knights quickly escaped into the woodland, a group of four or five, constantly attacking everywhere, beating the heavy knights to the point and finally having to take the lead in withdrawing from the battle. This kind of result made the generals of the other six major theaters of the empire shut their mouths.

After the fall of Scambrai, Marshal Chi Datong sat in the town of Jielin and personally commanded the soldiers, and started a tug-of-war with the Sect soldiers on the territory of the Holy See, and the jungle knights conquered one unfortified village and town and even smaller cities one after another, and the soldiers immediately dismounted and went to work - levy taxes. Whether it is gold, grain, livestock, or even hoes, plows, and other means of production, as long as they are valuable, they must be taxed at the poll rate. The Marshal knows quite well that the Boundary Forest Theater may not be able to last until the end of the war, and once the enemy has free hands, he will definitely give priority to solving this place, and instead of retreating at that time, it is better to weaken the Holy See's national strength as much as possible now.

For more than a year, with the Jielin as the dividing line, 100 miles to the east and 50 miles to the west, it basically became a no-man's land under the repeated tug-of-war between the Jielin Theater and the Holy See troops. Large tracts of farmland have been barren, and farmers who could have produced have become refugees who are begging for food. Near the Boundary Forest, the Jungle Knights on donkeys had already cost the Holy See a full six thousand men.

The failure of the siege of Hamburg City and the sweep of Chi Aotian's expeditionary force across thousands of miles in the Huayu Plain made the General Staff Headquarters of the Western Emperor re-understand the powerful combat power of the imperial army, so when planning the Battle of Jielin, all the most powerful armies in the eastern and western theaters of Jielin were included in the battle cluster.

The General Staff Headquarters of the Western Emperor Monarch chose this place as a new combat target with three major advantages: 1. The Boundary Forest Theater is surrounded by two major war clusters, the Holy See and Scambrai, which can be said to be 100% of the internal operations, and it is very easy to supply or increase troops.

2. The latitude of the Jielin Theater is low, and the temperature in winter is above 0 °C, so there will be no more and more difficult requirements for the supply line. Moreover, this is still a period of slack for the Holy See, and it will not affect the continuity of the war in the following year.

3. At this time, it can be said that the stars are shining in the territory of the Holy See, and more than ten high-ranking generals such as Mengton, Norton, Iron Hand Barricade, and Han Han are undoubtedly the key to ensuring the victory of the war. Nearly 100,000 ironclad troops took advantage of the majesty of the Aotian Expeditionary Force that had just won the whole victory, and the arrogance of the battle was high. Although the Dahaino cluster did not accomplish the set combat objectives, the appearance of the floating city still gave the soldiers and junior officers confidence. In addition, the Xuanqing Earth Dragon Knights were also put into action at the same time.

At the same time, with the right time, place and people, the Staff Headquarters of the Western Emperor has considerable confidence in this battle.

Of course, things didn't go so smoothly either.

In the autumn and February of the 6th year of the magic calendar, the 100,000 troops under the command of General Chi Hantong had recovered to their best condition after about two months of repair. On February 29, Chi Aotian's brother, Major General Chi Changyun, led an army of 30,000 ironclad led by the Black Dragon Knights and the Fire Lion Knights.

The base camp of the Western Emperor originally thought that this army would follow the route of the Chi Aotian Expeditionary Force and once again bloody the Huayu Plain to achieve the dual purpose of containing and weakening, and the base camp even made psychological preparations for exchanging space for time again. However, to the astonishment of more than forty scouts of the Holy See, Fanos, and the Khan Blood Mercenary Regiment, the direction of this army turned out to be south!

The south side of Tongyun Pass is a dense forest, the east side is a fairy forest, the west side is the woodland at the eastern foot of Shengxue Mountain, and there is a mainland road in the middle. 200 miles to the south, there are no human villages to be seen, except for the post station. Even if you walk on the mainland road, you can't see the sun when you look up - the rainforest is so dense that an adult banyan tree has a canopy of more than 100 meters in circumference.

Half a month later, the General Staff Headquarters of the Western Emperor finally understood the true purpose of General Chi Hantong's move - to build a city!

After the capital of the mercenary empire was conquered, except for some mercenaries who surrendered to Fanos, the other mercenaries, led by the surviving mercenary Heavenly King, entered the eastern foothills of the Holy Snow Mountain and the woodlands on the outskirts of the fairy forest to resist stubbornly.

The tenacious fighting consciousness of the mercenaries far surpassed that of the elite knight legion of the Xiusi Empire, which was also lost. This is also a subject of study for future generations.

Later scholars generally believed that the mercenary empire was the only commercial empire among the seven empires at that time, and that mercenary groups and merchant groups, large and small, had their own cities, and the inhabitants of the cities could move to other cities at any time if they were not satisfied with the city lord. This federal state structure gives citizens greater freedom and rights, especially for mercenaries who have made great achievements.

Even if the high-level mercenary group defects to Fanos, it will not necessarily be able to obtain greater benefits than the original, so most of the high-level mercenary groups and high-level mercenary fighters choose to resist.

Unfortunately, the mercenary group has a poor sense of cooperation with each other, and the mercenary group has a single class, and in the six years of the magic calendar, the mercenary group often sets the combat target at a small group of enemies with less than 100 people. In addition, these mercenary groups have lost their own cities, and there are no logistical supplies at all. This situation has led to the deterioration of the situation of these remnants of the defeated army every day.

The reason why Chi Hantong gave up the northern offensive and chose the south was to help these mercenaries build a city that would allow them to develop sustainably.

Chi Hantong believes that in the next few years, the direction of the Amy Empire's operations will definitely choose to be at home and in the Holy See, in this case, once the Eastern Legion of Fanos clears the remnants of the original mercenary empire, it will definitely become a new base for this pan-continental war, and it will continue to provide Fanos with food, money, recruits, equipment and other strategic resources. If the Holy See invests more manpower here to continuously brainwash the local population, the former mercenary empire may provide millions of soldiers to Fanos.

Therefore, His Excellency decided to plant a few nails on the south side before letting go of the attack on the Holy See. Build a city, send instructors, provide weapons and equipment for all arms, and provide food and grass supplies...... At least let the mercenary kings be able to create a virtuous circle on their own.

By the time the Western Emperor's staff base camp understood General Chi Hantong's true purpose, two Earth Cities 30 miles apart had already been established, and more than 300 mercenary groups, large and small, were coming in the starry night when they heard the news.

Another good and bad news also appeared in the autumn and February of the 6th year of the magic calendar, and the leader of Amy, one of the five mercenary groups known as the golden brain, actually made a stupid move - gave up and completely destroyed the city of Hamburg, which is of course on the good side. On the downside, the only mobile force in the northern mountains was released, and the army lingered in Scambrai for several days, and a small force of knights even attacked the mainland highway posts, tearing down several mainland roads to the imperial capital in succession to cut off support. Several dragon knights even soared above Scambray every day, and once they saw an air raid, they would always come down and do something. This forced the base camp to transfer a legion from the Boundary Forest Battle cluster back to the imperial capital. Unexpectedly, Amy, who was in an offensive posture, actually shook a shot and viciously pounced on the Sangan River war zone.

The jump of the small mercenary group cluster scared Earl Raybarton, the current general of the Sangan River Theater, enough. At this time, the elite combat forces in the Sanggan River Theater were concentrated in the troops defending Yi Hailan on the south bank, and except for a small number of swordsman troops in a few major cities on the north bank, the rest of the place was simply empty.

Earl Raybaton didn't expect that he would be so unlucky, just less than half a year after taking over, the black dragon blonde boy in the south came to inspect with his demon troops in three days and two days, and finally placed enough defensive forces in several main cities on the south bank, and now the north is also ......

While secretly cursing Marshal Dahaino's ability to use troops, the Earl sent four successive envoys in one day to ask for Scambrai's support.

Now that the Imperial Capital only has His Majesty's direct legions, less than 10,000 men, even the head of Scambrai City is not satisfied with this amount of troops. Besides, scattered light snow had covered most of the north bank of the Sangan River, and before the war, there had always been large-scale caravans on the mainland roads, and there were swordsman troops at the post stations, and the snow on the roads could be cleared quickly. Now after entering the state of war, people are panicking, just two light snowfalls, the mainland highway has already appeared in some places of silt and ice, and there are even similar man-made collapses in many places. In this case, the mobility of the knightly units was greatly reduced, not to mention the infantry units.

The reinforcements did not wait for the Earl of Raybarton, but the order was one - abandon the city on the south bank, shrink all the forces on the north bank, and hold on to the reinforcements.

With such an order, Lord Earl almost attacked the leader of the scout squadron in the base camp on the spot!

The 25,000 soldiers, except for the 15,000 elite troops who are directly controlled by the general, have long been split into various cities, and these soldiers are nearly 100 miles away from the farthest part of the Sanggan River Bridge, and it will take at least a week to evacuate all these soldiers to Heyang. In order to defend against the Yihai Blockade Corps, the Sanggan River Theater dismantled all the catapults and other war resources on the north bank and reassembled them on the south bank. Now to bring these supplies back, and to transport them under the nose of the enemy, not the enemy of one side, the young man who came from the north is the genius officer who defeated all the generals of Fanos, and he can make the boys of the Sangan River cross the river smoothly as big bags and small bags?

Earl Raybarton's question was answered accurately that evening, and the answer was, of course, no.

Amy now has six or seven dragon knights in her hands, how can Amy, who is extremely rich in resources, not take advantage of it? On February 3, the sixth year of the magic calendar, four dragons attacked the Sangan River Bridge under the cover of night, and that night, two of the three bridges were completely burned by the dragon's breath. The dragons had apparently had too much energy and enthusiasm, and considering that the humid weather in winter would be extremely unfavorable for the maintenance of the hull, they used the dragon's breath on the way home to roast the boats moored on both sides of the river. Originally, the dragon knights also wanted to sneak attack the base camp of the naval army in the Sanggan River Theater, but they were forced out by the crossbows of the company on Hanyang City. Even so, that night, the Sangan River was engulfed in flames.

Subsequently, the news that the Holy See's decades-long plan* had ended in failure also reached the headquarters of the Western Emperor's staff, and the news of the rekindling of the Zoroastrian flame that had been sent to him changed the color of all the senior priests of Scambrai. It is a pity that because the battle of Bombay City was quite clean and neat, the news of the reappearance of Chi Aotian's expeditionary force was not known by the peripheral informants.

In the autumn of the sixth year of the Magic Calendar, the situation on the continent of Eminole changed three times a day.
