The battle between the two great empires, was even more spectacular, vast, and cruel than the small fight between Wu Gang and the Blood Illusion Valley.

The two sides' big weapons were not on the same level at all, let alone in the same realm.

First of all, defending the city on one side, because they had been fighting with the Profound Nether Empire for a long time, had become the norm between the two large empires. However, because of this, the northernmost large city of the Honglong Empire not only had extremely tall walls, but also had extremely sharp defensive equipment.

All kinds of large and medium-sized crossbows were counted in hundreds, and as for the number of giant crossbows used, there was an uncountable number of them. Other than the records of the logistics department, perhaps no one would be willing to spend so much time to count those countless metal crossbows.

In addition to the crossbow, only the oil of fire and giant stones could be seen rolling down the city walls. Although these weren't common weapons, they had extraordinary effects in a true defensive battle.

Imagine, while waiting for the enemy to climb up the rope or bamboo ladders to the city, using a rolling log or a giant rock would immediately smash the enemy down the towering city wall. Even if they didn't die from the fall, they would definitely no longer have the strength to fight.

As for the fire oil, not only could it be used to deal with the enemy, it could also be used to burn the corpses of the enemies that had accumulated under the city.

The infinite sublimation of human intelligence in war is one of the necessary means of human evolution.

Now that he had the kerosene, he quickly associated it with the wondrous uses of boiling water and boiling oil. If he was going to be drenched from head to toe in boiling oil or boiling water, then it would basically be 'expensive'. Of course, it would also be 'boiling'.

Other than the swelling and lacerations on his body, the taste of the cooked meat was also indispensable. Of course, one should not think that this taste was very good, this was not the usual pig or sheep, but real human meat. The smell was both pungent and nauseous at the same time.

Of course, it was impossible to avoid aseptic isolation due to the lack of medical treatment, and there wasn't any modern nutrition liquid to describe it. Therefore, any soldier who was severely scalded would only have a certain death ending, but unlike those who died on the battlefield, they needed to suffer seven to fifteen consecutive days of pain, then slowly die from organ failure.

Fortunately, it was the turn of spring and summer, and the weather was getting hotter and hotter. Even the northern regions no longer felt chilly.

If it was winter and the north was freezing cold, even if a pot of boiling water was thrown under the city, it would quickly turn into ice. If he wanted to take off his armor, even if he kept pouring hot water on it, he would have to tear off a layer of skin.

War was this cruel. It had nothing to do with methods or methods, but rather, it was for the sake of survival.

On the defensive side, there were hundreds of moves, and there was an advantage in being on high. However, the attacking side was also fearless, and their siege equipment was also superior.

What was attacking a city? Attack the top of the city, break through the city gates, and take down the city.

Thus, apart from those who were scheming against the city, almost all of the generals would use this method of attacking the city that required a lot of effort, time, effort and effort.

Of course, for a large city that had stood in the border for so many years, wanting to break through it with just a plan to attack the heart was no different from wishful thinking. It was better to just attack the city from the ground!

Therefore, the direction of the siege ended. First, they had to climb to the top of the city walls and then break through the city gates. Only through these two methods could they successfully lead the army into the city.

The soldiers in charge of climbing up to the top of the city walls were also the most tragic part of the dead and injured in siege warfare. Before they managed to climb up to the top, they had to passively take beatings, whether they could survive or not.

Of course, even if all three points were prepared, if they were successful on top of the city walls, it did not mean that they would survive. After all, it was a different type of 'sheep into a tiger's den'.

It was not that the siege attackers lacked any defensive measures. Usually, these soldiers would be equipped with heavy shields and short crossbows, which would allow them to protect themselves to the fullest extent and also allow them to attack from close range.

At the same time, there was also the cover of fire from the arrow feather under the protection of the city's army, which suppressed the rain of crossbows above the city walls.

As for the troops responsible for slamming into the city gate, they didn't rush into the gate in a flurry right from the start of the battle. Instead, they were simply sending the enemy's heads away.

Smashing the door also depended on the opportunity. They had to wait until the enemy's fire had been suppressed to a certain extent, and also to ensure that no cavalry would come out of the city to bother them. Only then could they bring up the logs that had crashed the door, under the cover of their shields, and launch an attack on the city gate.

Putting aside these two melee classes, the other thing worth mentioning was the long-range firepower support.

As long as the crossbow was placed at the right angle, it could also launch long-distance attacks. Although its lethality was not as high as the top-down attacks, its lethality and destructive power was still far higher than the rain of arrows released by archers.

Therefore, after special modifications, the crossbow was also used as a weapon to attack the city. However, in order to lessen the resistance, the metal body of the crossbow was changed to a metal arrow and a wooden arrow. This way, the arrow wouldn't fall before it reached the top of the city because of its weight.

As long as there were enough people and they dared to fill the city with their lives, then besieging a city wasn't a particularly difficult thing. It was just a matter of time.

At the moment, the Profound Nether Empire was releasing an endless stream of fierce attacks towards the Honglong Empire. These attacks had never stopped since morning, and since the last time the Profound Nether Empire withdrew its troops, just two days had passed.

Raising their heads and looking at the sun which was gradually setting from the west, Situ Qingyun and Lei Sheng immediately felt chills run down their spines.

Profound Nether Empire did not take human life seriously, it was definitely not possible in the past. He did not know which part of Xianyu Hetu's mind was at the wrong place, and even after fighting for so long, he still did not show any signs of improvement. Why did he still continue attacking at all cost?

"Brother Qing Yun, Profound Nether Empire has always been this reckless in the past, sending herself to her death? "If this is the way you attack the city every time you come here, it will be difficult for you to stay in the north for so many years!"

"Hehe, Old Lei, you must be joking. If we attack like this every time, no matter how hard I defend and defend, I'm afraid the Northern Frontier will not be able to survive!" Today's situation had never happened before! I can't really figure out Xianyu Hetu's thoughts! "

"I think this old boy is here to take revenge for the scam you cheated him of that day? Didn't we purposely leak some information to that old brat later on? "

"I reckon so! This old fellow still holds a grudge! "

"Alright, I'll go and prepare. It's time for us to go on stage. Since we're here to support you, we can't let you guys face it alone!"

"Not good enough, the opponent is in the middle of a vigorous battle. If we suddenly change our defense, there will be a mistake. Wait a while longer!"

"What are you waiting for!"

"Wait until the gap between the attacks is met, I estimate that this attack will be the last one the other party will attack, after a series of failures, not only did they cause huge casualties in the Profound Nether Empire, but they have also dealt a blow to their imposing manner, I am afraid that they will withdraw their troops, and the next attack will be at least an hour later!"

"Fine, I'll listen to you!" You are the most familiar with this place. The marshal wants me to support you! If you want to do it, do it! "

"Slick!" Don't think that I don't know, the ace heavy cavalry unit in your hands is currently hidden outside the city. It would not be in keeping with the marshal's style to defeat the old man just because the old man had shown mercy. Are you trying to take the opportunity to take the enemy's cavalry? "

"You guessed it?"

"My appetite is really big!"

"The cavalry may not be able to be completely annihilated, but the enemy's heavy cavalry must be eliminated! This way, we will be able to win the upper hand in the following battle, and won't have to continue to stay in the city and wait to be beaten! "

"You guys are ??" Situ Qingyun suddenly had a strange and shocking thought, it suddenly popped out in his mind. He faintly felt that with Gongsun Ze Tian's temper, the possibility of such an idea happening was high.

"Don't ask me, I'm the same as you. I'm just guessing!" You don't know about our marshal, he always likes to hide everything and never reveal anything until the very last moment! "A pure human spirit!"

"Enough!" Just follow the plan! No matter what, he had to teach the other party a lesson this time! Otherwise, they really would not know that being reckless is also a price to pay! "

Lei Sheng left. He wanted to take his men to change clothes, and instead of saying that they were changing, it would be more accurate to say that they had put a beautiful layer of silver armor on the surface of the black armor. Although the weight did not increase by much, the degree of delicacy had increased by leaps and bounds!

Adding on yesterday's estimated release of news, most likely Profound Nether Empire already knew that the group of bright armored troops that they saw that day were just a decoration, an existence that did not even have the slightest bit of fighting strength.

Thinking about it, with Xianyu Hetu's personality, some things would probably be completely destroyed, and he could only hope that he would bring some vases with him during the upcoming battle. Otherwise, it would not be enough for him to fall.

Of course, if he knew that the troops that were specially used to decorate the area had been replaced with fierce beasts that had temporarily concealed their abilities, he would probably be on the verge of tears.

No one could have imagined that it was originally a cute and silly little white rabbit that could be bullied by anyone. However, just as it was about to make a move, it discovered that the other party was not an ordinary little white rabbit, but a ferocious and terrifying hare.

But now, Lei Sheng and his elite Black Armoured Army were preparing to play the role of a hare who was hiding under its' docility '. They would use their actions to tell the other party that not just any hare's ears could be reached out and soaked, but a tiger's butt couldn't be touched, and hoodlums' ears couldn't even be touched.
