After the establishment of the Heavenly Alliance and the Earth Alliance, the war between the north and south of the empire was on the verge of breaking out, and the tension of the sword was like a swift wind.

There were hundreds of large and small battles between the Heavenly Alliance and the Earth Alliance, the largest of which was three, which was called the "Three Great Northern Wars" in the history of the Tiansheng Empire.

The First Northern War occurred at the beginning of the establishment of the Heavenly Alliance, when the three major sects of the Northern Empire, Tianyu Sect, Zijin Pavilion, and Wuji Gate, met in Tianyu Mountain and officially formed the "Heavenly Alliance". Taking advantage of the fact that the Heavenly Alliance had just been formed, the Tianyu Sect's army, which was originally defending in the Yingzhou region, was lax, gathered the Earth Alliance army to storm the Yingzhou region.

Due to the ferocity of the Allied forces this time, especially when the Heavenly Allied Forces were not yet fully formed, the troops withdrawn by the three major sects of the Northern Empire from their respective states were still being repaired in their respective state capitals, and were not immediately transferred to the front line of the Yingzhou region, and the logistics materials of the Zijin Pavilion were still being prepared and had not been transported to the front line. This caused the situation that the Heavenly Feather Sect was most worried about before the establishment of the Heavenly Alliance at the beginning - the Heavenly Feather Sect used the strength of one sect to resist the coalition forces of the seven major sects of the Earth Alliance.

It is conceivable how difficult this is, although the Tianyu Sect has the advantage of occupying the Yingzhou Domain, but the number of people is several times less than that of the Earth Alliance Alliance, so at the very beginning of the battlefield situation, there was a "one-sided" defeat of the Tianyu Sect.

Since this is the first "Northern Expedition" since the formation of the Earth Alliance Alliance, the other six major sects except Wan Fenglin have not fought with the Tianyu Sect, so the newborn calf is not afraid of tigers, and all the sects want to "do it" well, especially the Antarctic Gate, which occupies the South China Sea and Yingzhou Island, is even more enthusiastic to play the role of "vanguard", so that the so-called "mainlanders" can see the power of "people from the sea".

Especially under Wan Fenglin's "bewitchment", everyone thought that the alliance army was several times the strength of the Tianyu Sect, and the seven major sects would attack together, even if the Tianyu Sect was the so-called "first major sect" of the empire, but because the Tianyu Sect occupied four major states in the empire, and the Yingzhou domain, the Yunzhou domain, The Dingzhou Domain is bordered by the Earth Alliance, so although the Tianyu Sect is strong, it is impossible to put all the military strength on the Yingzhou Domain, according to the need to defend the strength of the two major states, the Tianyu Sect can only mobilize sixty percent of its entire strength to come to the Yingzhou Domain, so the combined forces of the Earth Alliance should be about ten times the strength of the Tianyu Sect.

The "one enemy out of ten" should be a matter of victory.

For this war, Wan Fenglin can be said to be the elite of the sect, and all the troops in his Linzhou domain were drawn to the Suizhou domain, leaving only a small number of old and weak women and children to guard the state capital of the Linzhou domain-Nanxian City, and he had the courage to make a desperate bet. The other six major sects also concentrated all the troops sent to Suizhou and handed them over to Wan Fenglin for "command".

At the same time, the allied forces also set up a combat command headquarters in Dongsuicheng, the capital of Suizhou, called the "Northern Expedition Base Camp", and also set a slogan called "The Northern Expedition will not be completed for one day, and the base camp will not be withdrawn for one day." Since the leader of the Earth Alliance is Wan Fenglin, and the initiator of the Northern Expedition is also Wan Fenglin, there is no accident, Wan Fenglin's suzerain serves as the "Grand Commander" of the Northern Expedition, and the suzerains of the other six major sects of the Earth Alliance serve as the "Deputy Commander". Since this was the first contest between the Earth Alliance and the Heavens, according to Wan Fenglin's requirements, the sect masters of the six major sects all came to Dongsui City in person to carry out the Northern Expedition.

At the same time, the Earth Alliance also set up a front-line command in Black Stone City under the Hengduan Mountain Range, the north-south dividing line between the Suizhou and Yingzhou regions, and the "offensive department" in Wan Fenglin's "two direct departments" served as the vanguard officer.

The Wanfeng Lin Sect is divided into "four straights, two departments and two rudders", "four straights" refers to the "four non-halls", which are the non-speech hall, the non-silent hall, the non-hearing hall, and the non-listening hall, which are responsible for the three internal affairs of the sect and the special affairs arranged by the sect master, mainly internally, and the "two departments" refer to the "offensive department" responsible for commanding the armed forces of the Wanfeng Lin sect - the "Wanfeng Army", and the "defense department" responsible for the guard of the Wanfeng Lin sect , these two are the core of Wan Feng Fenglin's external appearance, one is responsible for offense, the other is responsible for defense, each performing its own duties, and both aspects can be balanced. In particular, the "offensive department" was developed from the vanguard unit that was the best at fighting wars in the original Wanfeng tribe, and it was also the core force of Wan Fenglin's acquisition of the two major prefectures in those years; the second rudder refers to the "Suizhou rudder" in which Wan Fenglin was responsible for managing the Suizhou region and the "Linzhou rudder" in the Linzhou region.

The head of this "offensive department" is equivalent to the actual commander of the Wanfeng Army, because such a person serves as the person in charge of the offensive of the allied forces in the border area, which also shows that Wan Fenglin attaches great importance to the Northern Expedition, and even has the courage to win.

Since the Heavenly Alliance was just formed, and the Earth Alliance had been preparing for this Northern Expedition for a long time, Wan Fenglin was also eager to make contributions, so the war started quickly.

The Earth Alliance was spearheaded by the Wanfeng Forest Offensive Department, and began to carry out a large-scale attack on the "Gorge Pass", the gateway of the Tianyu Sect's Ying Prefecture, from Black Rock City. Since this is a joint operation carried out by the Earth Alliance Alliance, the number of attacking armies far exceeds the number when only Wan Fenglin's family attacked, and because it was the first joint operation, the seven major sects of the Earth Alliance each used their own offensive methods, which is the so-called "each showing his magical powers". In the face of the tide of Earth Alliance troops, the defenders of the Heavenly Feather Sect, who had been tense all the time, obviously felt more pressure than the previous times.

In the end, due to the huge gap in strength, it only took two days for the gateway of the Tianyu Sect in the Hengduan Mountain Range to be captured by the Earth Alliance, and the passage between the Black Stone City of the Earth Alliance and the Gap Pass of the Heavenly Alliance was opened.

In the face of the first victory of the Northern Expedition, the seven major sects of the Earth Alliance were all excited, especially the other six major sects of the Earth Alliance who had not fought with the Tianyu Sect, and finally felt that the Tianyu Sect, the number one sect in the empire, was not invincible.

For such a victory, Wan Fenglin obviously had to be "calm", because they had fought with the Tianyu Sect many times and knew the true strength of the Tianyu Sect, and this was the so-called Gorge Pass was just an opening to enter the Yingzhou region, and they had to go to the state capital of the Yingzhou region, "Yingqing City", as well as the "five passes and six cards" along the way.

After entering the Yingzhou region through the gorge pass, the combat effectiveness of the Heavenly Alliance Alliance was still strong, according to Fenglin's strategy, the Heavenly Alliance alliance army did not entangle with the defenders of the Tianyu Sect in every town in the state region, and immediately divided into three offensive teams according to the established strategy.

The Chinese army is led by Wan Fenglin, and its military strength includes the armed forces of the three major sects such as Wanfeng Forest, Linggu, and Nanhai Sea, but because the strength of Linggu and Nanhai is weak, this team actually mainly relies on Wanfeng Army, and the Chinese army is still commanded by Wan Fenglin's "offensive department", which is directly into Yingqing City from the front.

The Western Army is led by Lingyun Hall and Huazong, and its military strength includes the forces sent by these two major sects for the Northern Expedition, according to the deployment of the Earth Alliance, after this Western Army enters the Yingzhou Domain, it will go directly to the area bordering the Yunzhou Domain in the west of the Yingzhou Domain without stopping, build a "western" defense line, and prevent the reinforcements from the Tianyu Sect from the Yunzhou Domain.

According to the deployment of the Earth Alliance, after the northern army entered the Yingzhou region, it made a detour from the eastern part of the Yingzhou domain without stopping to the area bordering the Jingzhou domain in the north of the Yingzhou region, building a "northern" defense line to prevent the reinforcements of the Tianyu Sect from the Jingzhou domain.

For the arrangement of Wan Fenglin, the leader of the Earth Alliance, several major sects in the region originally had opinions, according to everyone's thoughts, it should be that after entering the Yingzhou Domain, they should concentrate the force of the Earth Alliance and capture Yingqing City in one go. Instead of carrying out the so-called division of troops and encirclement according to Wan Fenglin's current deployment, it actually dispersed the overall strength of the coalition army.
