While the southern battlefield was victorious, the northern battlefield was still like a pool of stagnant water - the undead would be weakened in combat effectiveness during the day, and they would all hide in the depths of the caves, and the defenders of the Silent City would simply repair during the day.

It wasn't until the afterglow of the setting sun dissipated that the army of the undead came out of the cave again and launched a second attack.

However, unlike last night's large-scale attack, this attack was more like a temptation, with waves of undead rushing towards the city walls, seemingly immense, but they were all cannon fodder-like existences, and the real main forces were all watching from the rear.

From then on, the offensive on the northern battlefield seemed to have entered garbage time to deal with things, and it was as if the two sides had reached some kind of tacit understanding, the undead army attacked after sunset, retreated at midnight, and retreated to their strongholds during the day, while the soldiers of the Silent City recuperated in the defensive line, and the two undead monarchs summoned new undead in the cave.

However, everyone understands that the undead side is afraid, and they are also testing whether the previous light rain will appear on the battlefield again.

And this protracted battle has been fought for more than a week, but the light and rain of that night has never reappeared, no matter how much pressure on the front line is, even if the new skeleton vultures attack again, there is no light rain to come to the rescue.

It seems that the light rain that appeared that night was just a one-time magic item.

And Isu, the real initiator of the light rain, said that he was also desperate!

He was really having fun that night, and the 30,000 mana crystals said that he would burn them, but when the burn was finished, he remembered that he was distressed, it was 30,000 mana crystals! That's what he saved for half a month, plus his previous savings that he managed to save up!

With his current meditation efficiency, even if he meditates every day except for eating and going to the toilet, he can only condense more than 2,000 mana crystals.

2,000 mana crystals, if they were placed two months ago, they would definitely make him laugh out loud in his dreams, but now...... Put a minimum of [Radiant Rain]?

Don't be funny, what can a rain of light with a diameter of twenty meters do? Is it a shame to take it out?

So after discussing it with Feige, Izuy decided to hide the card until the army of the undead on the opposite side launched a general attack, and then took out the card and played a big one.

Just like on the first night, a rain of light covered the entire defense line, covering an elliptical area nearly 500 meters long (long axis) and more than 50 meters wide (short axis), forcing back tens of thousands of undead in one fell swoop.

Of course, the main reason is that for more than a week, the two undead monarchs have not reappeared, and if these two undead monarchs are not taken down, this war will never end.

"Wait for three more days, three days later, the reinforcements from the southern battlefield will arrive, if the two undead monarchs don't appear at that time, we will go directly to the door!"

Feige also has a fire in his heart, although this battle has completely fallen into garbage time this week, but even if it is garbage time, it is going to die!

Even if the other side is sent up with some cannon fodder troops, but they can't stand the large number, every night there are at least tens of thousands of low-level skeletons and ghouls to join the siege, and the warriors defending the city are only a few thousand, even if the strength of the warriors is stronger, even if the warriors will take turns every time they fight, but there is always a time when there is a mistake, in the face of the endless sea of undead, once there is a mistake, it will be at least a serious injury.

In the past week or so, more than 100 soldiers have lost their lives on the battlefield, and more than 500 have completely lost their combat effectiveness due to disability, and the defenders of the Silent City here have been reduced by more than a fifth.

However, the more than 2,000 gunners and gunners from the Golden Flame Edge did not suffer much loss, and these Golden Flame Blade's troops were all long-range troops, including the reinforcements transferred from the southern front through the portal a few days ago, more than 2,000 people and artillery were arranged to defend on the second high wall, and they were rarely attacked by the undead.

However, although the soldiers of the Golden Flame Edge have not been reduced, the guns have been damaged a lot, and in the past week or so, the Golden Flame Edge has sent more than 500 new dwarven guns and twelve dwarven cannons to this side through the portal to replace those damaged guns.

In this regard, General Jin was also distressed, but he still continued to transfer materials to the northern front, and then transferred a group of "reserves" to strengthen the long-range strength of the northern front.

On the other hand, the army of the undead has already lost more than 100,000 undead in this week, and the data alone seems to be countless times worse than that of the Silent City, but in fact, there is no loss at all.

The loss of these low-level undead was all summoned by the two undead monarchs from the undead plane, the necromantic plane and other half-planes attached to the current world, as well as the soul stone mound, as long as the two undead monarchs did not die, how many such cannon fodder troops would be.

After more than a week of fighting, the strength of the undead army has not been lost in the slightest, but the elite troops in it have accumulated more and more, if you wait for another half a month, maybe the Silent City side will have to surrender unconditionally.

Of course, this is only the worst plan, after all, the control of the two undead monarchs is also limited, especially when controlling the elite undead, even the Nos, who is known as the Awakener, can only control the number of more than 10,000, and a part of the quota must be reserved to control the ordinary undead.

Sure enough, in the next three nights, the attack of the undead became more and more intense, and some elite undead also joined the siege sequence, especially on the third night, after thirty-two skeleton mammoths and more than twenty corpse giants participated in the siege, even the legendary powerhouse who had been unable to endure had to go down in person.

In the battle that night, although the legendary powerhouse on the side of the Silent City killed all the bone mammoths and corpse giants, he was also struck by the two undead monarchs, if it wasn't for the fact that Isu used [Radiant Rain] again and used [Punishment Thunder] to force back the awakened North North, maybe this guardian from the god and demon battlefield would have fallen here.

Although the Awakener North was surprised by the resurgence of the Radiant Rain, he did not pay enough attention to Ysu, and naturally did not guard against Ysu's [Punishment Thunder], but when the thunder representing destruction and purification appeared, North did not resist, but summoned more than a dozen ghosts to line up in front of him, greatly weakening the power of [Punishment Thunder], and he himself was only slightly injured.

Early the next morning, the reinforcements from the Silent City, who had arrived overnight, finally arrived at the northern defense line, and after a short rest, they launched an attack on the cave where the undead were hiding at noon, and when the army of more than 13,000 people arrived at the entrance of the cave, they found that what awaited them was somewhat different from what they expected.
