The Black Gold Group launched a consumable siege tactic, arranging long-range artillery fire to attack the city at the edge of the defensive artillery fire circle, and then arranging two tank-based shield corps in front to suppress the formation and eradicate the artillery batteries on Wolong City.

After a day, it turned out that the benefits were not large, Wolong City, as the first fortress of the Four Seas, was naturally first-class, and the forts were protected by strong small pillboxes, coupled with the condescending distance, the group's selection of artillery fire was not able to pull out a few for a day.

The management council deliberated and decided to advance the battle line, and only by entering the fire circle could they effectively attack the batteries on the city wall, and they expected to lose three legions in exchange for the siege of the city gate of Wolong City.

Of course, Yu Lihuang is not stupid, as soon as the other party advances, he will send the steel corps out to strengthen the firepower, although it is to fight more with less, but with the cooperation of the artillery fire of the defense city, the tank corps of the group can not be pushed to 500 meters under the city, and they lose their vision advantage when it gets dark, and they are trapped in the urn city to continue to fight or suffer, they can only withdraw outside the fire circle as soon as it is dark, and wait for dawn to continue.

For three days, the siege did not have any significant effect, and the management would be in a hurry.

"Ma's, when did this Yu Lihuang become a turtle, as soon as you hit him, he poked his head and hit you, and he withdrew as soon as you withdrew, but he didn't come out to fight head-on."

"We can't delay it, it's getting colder and colder, although the supply trucks are coming to camp, according to this method, we have to fight for a month, and we must break the city within ten days."

"When all the legions arrive, we will have twenty-five combat legions, then take ten for the city to break, and the ten legions will not believe that the walls of Wolong City will not be beaten into mud!"

"Then increase the troops, he will not send a steel legion out of the city to defend, we will send ten in, and ten for one will have to take the city gate!"

The Black Gold Group launched a fierce attack, and nearly 600 chariots from the ten legions, like a swarm of mosquitoes in the car, entered the urn city and launched a fierce attack on the gates and walls of Wolong City.

Yu Lihuang gritted his teeth and held on for a day, the Iron Legion suffered a lot of losses, so it could only retreat to the city at night, and the Black Gold Group did not withdraw early at night this time and was still attacking the city, Leng Feng continued to go out of the city with a legion to resist, lest the Black Gold Group chariot approach the city gate and lose its defensive advantage.

"Ma, it's too embarrassing to fight like this, is there any news from my brother?!" Yu Lihuang asked Chen Zhenhai.

Chen Zhenhai shook his head and said, "At present, I only know that the city lord and the fortress are still in Lin City. ”

"If you keep it like this, the loss is not small, do you think we should send more legions out to exterminate these people in the urn city?!" Yu Lihuang has been a violent man for a long time, and it is okay to keep it for three or five days, but it is not his temperament to keep it for a long time.

Chen Zhenhai hurriedly persuaded: "Lord Yu must be stable, the enemy conservatively estimates that there are also twenty legions, they have already set up formations in Longtou and Longwei Mountain, we will be attacked from three sides in front of us, so the cost of destroying the enemy of the urn city will be very expensive, the city lord must make sense for us to let us defend the city, and the cold night season will make those more than twenty legions lose half of their combat strength." ”

"Alas, the cold night season is unpredictable, in case we don't enter the deep cold within ten days, our city wall will be worn down by the group, which is too risky." Yu Lihuang is right, if he doesn't enter the deep cold, it will not have much impact on the Black Gold Group, the enemy has many soldiers and vehicles, and the city will always be broken every day, and there will be losses every day to defend the city, and it will be even more difficult to fight if the city wall is lost.

Chen Zhenhai firmly believed: "Lord, the city lord can get out of the cage, and now he has attacked the city and plundered the land with less attack, his tactical strategy has never made mistakes, as long as we consume energy until the deep cold comes, we have Wolong City to recuperate, and then the enemy who loses sufficient power and freezes will be defeated with one blow." ”

"Ah, okay." Yu Lihuang could only continue to defend the city, and the legions in the city took turns to rest and defend the city, but he didn't know how long he could hold on to it.

The Black Gold Group attacked until more than three o'clock at night, and the temperature was very low, so they could only retreat first, they did not dare to completely withdraw from the urn city, and began to attack the city again after a short rest until dawn.

Yu Lihuang is anxious, and Heijin Group is also anxious, one is looking forward to the deep cold, and the other is afraid of the deep cold.

Ding Sancheng was even more anxious to rush to the city wall, the new tactics attacked for three days, but the army could not press under the city wall to attack the city gate and the city wall, and could only rely on the long-range artillery grinding behind.

Yu Lihuang was about to explode when he heard this, if it weren't for Bai Yucheng's persuasion, he would have rushed out with a giant bone.

The temperature plummeted by 8 degrees overnight, reaching minus 30 degrees Celsius at its coldest point, indicating that the cold night was coming, and it was likely to reach below minus 40 degrees Celsius in three to five days, and the temperature could freeze to death in the wild at night.

Yu Lihuang looked at the cold wind in the window and smiled, finally waiting.

The management will be in a hurry, although they have brought a lot of supplies, if there is no cold night to last for a month, it is estimated that there will be a cold night for up to half a month, plus the siege is not conducive to consumption, whether it can last half a month is unknown.

"Attack, don't care about the price, you must capture Wolong City!"

"Tell Ding Sancheng to let the chariot rush down the city, and kill those who retreat!"

"I want to take Wolong City at all costs, so that all the legions are ready, and if one legion is gone, the next one will be on top for me!"

"Yes, I don't stop attacking day and night, I don't believe that I can't take Wolong City in three days!"

The group's combat management will dare to make such a decision because there are many legions in their hands, and more importantly, those soldiers are worthless in their eyes, as long as they take Wolong City and take Zhang Zhen, it is equivalent to getting the old world for them, and they think that they will live like heaven in the old world, and they have never cared about the lives and deaths of their people and soldiers.

The enemy's reckless attack on the city had a remarkable effect, one by one the chariots rushed down the city like a chariot of death, and after a day and a night of fighting, the remains of the chariots were everywhere in front of the city wall, and the legions in the city could not advance out of the city, and could only fight at the city gate for a while.

Since the city gate could no longer be harassed by fire, the enemy established a position on the wreckage of the chariots after losing the chariots of four legions, and hit the head of the city in the fire of the anti-aircraft batteries at any cost, and the batteries on the city wall were knocked out one after another, and the entire city wall began to be mutilated.

Wolong City fell into a situation where it was completely defeated, and the city gate began to crack, so Yu Lihuang could only set up a formation in front of the city gate to prevent the enemy from rushing into the city too early.

"The fortress hasn't moved?" Yu Lihuang doesn't like a completely passive situation, and would rather fight to the death.

Bai Yucheng shook his head.

"What's wrong with my brother, the cold night is coming!" Yu Lihuang was anxious like an ant on a hot pot, and now if he had no external support, he could only wait for the city to break down and start a war in the city. "The walls will last for three days at most, and then the enemy will be able to rush in."

Bai Yucheng pondered: "The cold night only came, and it was not yet extremely cold, and the impact on the Black Gold Group was not very great, the city lord must be waiting, this Wolong City Urn City has no outer city wall, and the outer city wall is gone, and there is an inner city wall, we can still delay it for three more days, it is really not possible to transfer all the legions to the core area, and use the street to establish a defense, so that we can hold out for at least three days, if the second master comes back with the fortress, at least half of the enemy's troops enter Wolong Mountain, this is the real urn to catch turtles." ”

"Eh, that's the only way, there's no way to attack the city now, I'm like a turtle, you go and cooperate with City Lord Chen to establish a defensive line." Yu Lihuang could only hold on at this time, without foreign aid, the outside of the city was stuffed with chariots, and he couldn't fight at all, just like the situation of attacking Wolong City and the Four Seas at that time.
