In the second stage of the Northern Expedition, the Eagle Banner wolf pack attacked Shimen and destroyed its baggage. On that day, the Republican Red Army crossed the river in an all-round way, the autumn wind swept away the leaves, and the torrential rain destroyed the city, breaking the rebels in the two provinces of Jin and Lu. When the enemy heard this, his five bodies were chilled, and he was frightened, and he summoned his generals to discuss moving the capital to avoid the edge. The kite is powerful and shocks China. - The Republican Chronicles

...

In the first year of the collapse, the most brilliant general of the Republic fell at the age of 39.

Because he was too young and devoted his life to the military, he failed to leave behind books and works that would affect future generations, and he was buried with him.

In fact, Leng Luan was quite interested in ordnance and equipment during his tenure, and personally designed a 29-ton light tank, but military experts felt that the reliability was not as good as the main battle tank at that time, so they did not agree with it.

However, after the cube invaded and the beasts roamed the country, the scientists of the Republic of the Glory stumbled upon this drawing, and after further discussion, they were shocked by the design, and launched a special research project to build this type of tank.

Named the "Defender of the Fatherland" by Leng Luan, this type of tank weighs 29 tons, has a maximum speed of 80 km/h, can cross trenches and climb over vertical walls, in addition to weapons such as 12.7mm machine guns and 35mm grenade launchers, the most eye-catching is undoubtedly the 125mm main gun.

The cannon of this caliber can penetrate any known armor and is generally used in heavy main battle tanks, which appear bulky to load on a light tank.

But in response to this, Leng Luan very boldly abandoned the frontal composite armor of the Defender of the Fatherland in the design, and on the basis of ensuring that it could withstand conventional firearms, all the excess armor was removed, and the load was freed up for the 125mm main gun and a powerful fire control system.

According to Leng Luan's concept, she believes that in modern tank warfare, the leading position of main gun technology has far exceeded that of armor technology, in fact, it is also true, no matter which country's tank you are, which country's armor, encountering the most advanced tail stabilized shelling armor-piercing projectile is a cannon paralysis, unless the armor can be increased to 2000mm, but then the weight will increase greatly, one is that the engine is not up to the level, and the fuel consumption is huge. The second is that the tank directly became a target and was completely scrapped.

In response to this, Leng Luan put forward the core idea: "find first when encountering, hit first after discovery, and break down after hitting"

Therefore, Leng Luan vigorously improved the power of the main gun and the fire control system on the basis of abandoning the thick armor, ensuring that one of the three points in the core idea was not missing.

This line of thinking was not very realistic in tank warfare in the old era, because it was easy to be destroyed by anti-tank troops, and the gains outweighed the losses.

But in the Honkai Era, when the opponent turns into a fierce beast, this line of thinking suddenly changes from "mediocre" to "advanced".

The battle in the first year of Honkai Impact has proved that the main battle tanks of the old era are very vulnerable in the face of fierce beasts, even if they kill a few first, because their mobility is too slow, once they are surrounded, there is no place to run, and no matter how thick the armor is, it will be torn, not to mention encountering large mutant creatures, it is really impossible to fight, and it is impossible to run.

However, the two core characteristics of the Defender of the Fatherland tank, mobility, firepower, and mistakenly broke through such a dilemma.

The high speed and mobility of the Fatherland Defenders make it difficult for them to fall into the encirclement, and their powerful firepower and precise fire control make it easy for them to destroy the beasts from a distance.

The Federation has a lot of money, and directly took the reward points to the cube to exchange for materials, and made the "Giant God Tank", a steel monster that is beyond the times, and dares to fight with the face of the fierce beast.

The Radiance of the Republic does not have such conditions, so it can only avoid hand-to-hand combat as much as possible on the materials and foundations of the old era, ensuring that it can kill the fierce beast from a distance of thousands of meters, and the Defender of the Fatherland is the most suitable choice.

Therefore, after the potential of the Guardian of the Motherland was discovered, it was mass-produced in the Radiance of the Republic, replacing the heavy tanks of the old era as the main battle equipment, helping the Radiance of the Republic to survive the most difficult days, and it was also known as the "only legacy" left by Leng Luan to the Radiance of the Republic.

In the Northern Expedition, especially in the current battle of crossing the river, the defenders of the motherland have become the most dazzling protagonists on the battlefield.

As the news of the fall of Shimen spread throughout the north and south in an instant, the morale of the rebel defenders in the two provinces of Jin and Lu was greatly shaken, and the Defenders of the Fatherland were known for their mobility, and after crossing the Yellow River, the tank assault clusters composed of the Defenders of the Motherland divided the rebels' front like sharp knives.

If Leng Kite used the crude theory of large-depth battles in the first stage, then in the second stage, she used the "interspersed division" that the generals of the old republic had played badly, carried out a "surgical" precise division of the rebels' strategic base areas, and concentrated superior forces to annihilate them one by one.

For this kind of rotten tactics, Jiang Zong should have been able to play with ease, but as the old saying goes, "the army is defeated like a mountain", the fall of Shimen is too big a blow to morale, even if the gods descend to earth, they can't imagine that the wolves will actually start a coastal landing battle.

Therefore, even if the general Zonglian, who was at the head of Beijing, issued several military orders, the front line was out of control, and the military orders could not be carried out, and all theaters began to fall apart.

There are even rumors that the paratroopers of the Republic of Huihui will be airborne in Beijing, causing chaos in the whole city, you know, Leng Kite's slaughter in Xuchang happened not long ago, who dares to guarantee that the butcher's knife will not cut his head?

In the face of such a momentum, the general Zong, who was in the head of Beijing, really tried his best, but as the saying goes, punch the master to death, and fight it into a pot of porridge like now, no matter how powerful a commander you are, no matter what tricks and tactics you are proficient in, no matter how many years of military experience you have, it is useless!

Now it's a matter of who has the bigger fist and which side of the soldier is more ruthless.

Jiangzong even sent a large number of special operations troops one after another, preparing to behead Leng Kite's command and assassinate this former beloved disciple, but all the killers sent out have lost contact.

In the end, in desperation, Jiang Zong summoned all the senior commanders in Beijing and held a secret meeting to discuss whether to move the capital to avoid Eagle General, but there were serious differences of opinion.

Some people suggested moving the capital north, because in the current war situation, the capital of Beijing is already very close to the front line, and it is definitely a disaster to really burn the flames of war here.

But there are also people who swear to defend the head of Gyeong, after all, every rebel is a republican people, and the capital of Gyeonggi is the highest symbol in their hearts and cannot be violated!

In modern history, Beijing fell three times, from the Anglo-Chinese War, to the invasion of China by the Eight-Nation Alliance, and then to the bloody war of resistance against Japan, this Chinese king was taken away by foreign enemies several times, but for the dignity of the motherland, how many martyrs have been sacrificed one after another, forgetting their lives, charging bravely in the rain of bullets, going crazy and killing into the enemy formation, and piling up the road for their partners with their lives, which made the red flag rise again in Beijing.

In the first year of the collapse, in the face of such mountains and rivers and the destruction of the country, the fierce beasts were rampant, the 38th Group Army of the Republic fought to the death, and none of the whole army flinched, and the deputy commander Liu Duyi was martyred, and he saved the head of Beijing from the sea of blood in the mountain of corpses and prevented the fourth fall!

In the eyes of the rebels, this is faith and glory, and now that they are guarding the head of the capital, how can they allow it to be taken away by the hawks of the Republic!

In the end, the two factions were deadlocked and ended in nothing.
