Just as the situation in the European region was reversed, the army of the undead on the American side finally began to attack the fortress built by the North American coalition in Nicaragua.

At this moment, the North American coalition finally got a glimpse of what the Sea of Skulls was.

Although as a human being, I have seen the so-called Sea of Skulls in movies or games before, but compared to the scene in front of me, it is completely pediatric. This kind of shocking scene is not at all something that movies or games can show.

The head of the North American coalition was a high-ranking member of the Rand family named Louis. Rand.

Louis is definitely the top ten masters in the Rand family, his own rank has reached the late second order, and his actual combat power is comparable to the peak of the second order.

Now Louis's eyes were grim, looking at the army of skeletons swarming all over the mountains, and his will did not waver in the slightest.

"Luis, I think we should send more masters from the country." Du Men, the three leaders of the Angel Alliance, frowned and said.

Louis said: "There is no need for the time being, the current sea of skeletons looks extremely powerful, but their strength is not very strong, most of these skeletons are only second-order strength, with the defensive ability of our fortress, these skeletons cannot be attacked." ”

Louis is right, most of these skeletons are indeed second-order, because many of them are transformed from humans or demonic beasts, and their strength before their death is basically at the second-order level, and now they are transformed into skeleton soldiers, and they are also only second-order.

However, the second order also has the benefits of the second order, because the border passage does not have any restriction effect on the second-order alien race at all, and the undead clan can send out as many as they want. This is also the greatest advantage of the undead.

Of course, at this moment, the army of the undead outside the fortress is not only second-order skeletons, but also other powerful undead, but now these undead have not yet been dispatched, and they are still watching from a distance.

As soon as the countless undead approached the range of the fortress, countless arrows were immediately shot down on the city wall.

For a moment, the undead were like a storm of death. One by one, they turned into dry bones.

But the undead are not afraid of death, especially these low-level undead, who even lack basic wisdom, which is inferior to demonic beasts of the same level. Ignoring the white bones on the ground, they rushed towards the walls of the fortress like waves of the sea.

The arrow towers on the city walls played a huge role, harvesting the lives of the undead one after another.

A few hours had passed, and the ground had been covered with a thick layer of white bones, but the death of these skeleton soldiers was not in vain, and they advanced the battle line to a position only a hundred meters from the fortress.

As the battle progressed. Skeleton archers of all sizes began to charge, suppressing the humans on the walls from a distance.

The defenders of the fortress suddenly felt the pressure increase, and the soldiers of the war continued to die under the bone arrows.

Fortunately, the mercenary masters in the Arrow Tower and the Magic Tower played a huge role, and the high-ranking undead mixed in the army were shot by the mercenaries before they could rush close.

If it weren't for that, I'm afraid this fortress would have been breached by the army of the undead.

Seeing this scene, the undead in the distance also knew the threat of those arrow towers and magic towers to themselves, and the high-level of the undead army did not dare to act rashly at this moment, the main reason was also to be afraid of those defense towers.

The low-level undead have no wisdom and are not afraid of death. It doesn't mean that the high-level undead don't have intelligence.

Where the undead army commander's tent was, a black warrior covered in darkness rode a ghost bone horse, and he was not at all distressed by the death of so many skeleton soldiers under his command. In the hearts of the high-level undead. Skeleton soldiers are pure cannon fodder, and they are of little use except to send them to death.

Besides, these skeletons are all transformed from killing humans or demonic beasts, even if they are all dead. It will not hurt the roots of the undead.

"Grand Commander, my subordinates think we should find a way to pull out those towers first." A skeleton shelf covered in black robes next to him said, This is a skeleton mage. It is an advanced variant of skeleton soldiers, and its combat power is not at all comparable to ordinary skeleton soldiers. The most important thing is that once a skeleton soldier becomes a skeleton mage, its growth level will be much higher.

The skeleton mage in front of him is the right-hand man of the Black Warrior Commander, and he is also a think-tank figure, with a pivotal position in the entire army of the undead.

The Grand Commander said: "I naturally understand, but the defense tower is not so easy to push down, and we have no other way but to rely on the army to push it through. ”

The skull mage's jaw twitched continuously, and he said, "Grand Commander, have you forgotten the ghost we have? As long as the ghosts are out, aren't those arrow towers still handy? It's just that the magic tower is a little troublesome, and the ghost is naturally restrained by magicians. ”

The Grand Commander's heart moved, he really didn't think of using the ghost just now. Wraiths are also a type of undead, and although their status among the undead is not as high as that of the Black Warriors, it is also comparable to the Bone Warriors. Most crucially, Wraith has a very important trait, which is immunity to physical attacks, but it also has a weakness, which is a tenfold increase in magical damage.

In the fortress in front of him, although the number of magic towers and arrow towers is about the same, there are four or five, but in terms of the actual role, the arrow towers are much higher, after all, each arrow tower can attack dozens of targets at the same time, if there are no these arrow towers, their suppression will be greatly reduced.

"You're a good one, let's destroy the Arrow Tower first. Immediately mobilize a team of Wraiths and be sure to knock down all the towers. The Grand Commander said.

The skeleton mage went down immediately, there were only 50,000 ghost troops in their army, and the lowest rank of each ghost was the peak of the third order, which definitely belonged to the elite of this army of the undead. Such an army can only be mobilized by the commander or by himself.

After a while, 10,000 ghosts floated over, and the temperature around them instantly dropped a lot.

Under the order of the Grand Commander, this 10,000 ghost troops directly launched an attack, aiming directly at each arrow tower. It's so fast that it's much faster than the skeletons.

……

"What the hell is that?" Dumen watched the black mist sweeping in the distance, and was shocked, they had never seen such a mysterious thing.

Louis's eyes widened as well, but he reacted very quickly, and immediately said, "It is said that there is a class called Spirits in the undead army, so this may be it." We're in big trouble. Organize the mages at once, and be sure to intercept these ghosts. ”

"Oh no, the other party's target is the Arrow Tower." Dumen exclaimed.

Louis immediately got up and ran in the direction of the arrow tower. At the same time, he shouted: "Gather the magicians among the mercenaries to guard the arrow tower!" ”

The defenders in the fortress are all the elite of the North American coalition army, and the order is naturally issued very quickly, as for those mercenaries, all of them are early fourth-order existences, and after hearing Louis's roar, they rushed directly to the direction of the arrow tower.

There are seven or eight thousand mercenaries in this fortress, which is almost all the mercenaries hired by the entire North American coalition army, and there are naturally many magicians among them, as many as two or three thousand.

There are three fortresses here, each of which is guarded by nearly a thousand magicians. This is also the main force of humanity to defend against the attack of the undead.

In just a few seconds, nearly a hundred magicians stood under each arrow tower, including mercenaries and the warriors of each faction.

"Kill!" The wraiths finally made their way to the fortress, their losses negligible, and all the arrows they shot passed through their bodies as if they were shooting through the air. The only ones who had done some damage to them were the ordinary mages on the city walls, but they had killed no more than a thousand or two thousand spirits.

The ghost rushed under the city wall and floated directly onto the wall. Those human warriors who were in front of them suddenly fell into bad luck, and many of them were killed in an instant, this is the gap between the third-order peak alien race and the second-order warriors.

Fortunately, these ghosts did not deliberately kill the warriors on the city walls, and their goal was very clear. That is to destroy the arrow tower. Therefore, after gaining a foothold on the city walls, they pounced directly on the arrow tower.

However, the magician over there gave them a blow in the head, and a large area of group attack magic covered them. Under the tenfold damage inflicted by these spirits, a large number of ghosts died on the spot.

The ghosts that rushed to the front were the first to dissipate, but they also created an opportunity for the ghosts behind. They rushed in front of the magicians in an instant, and the shadowless and invisible claws attacked indiscriminately, causing some damage to these magicians.

Fortunately, these mages are all small masters in the early stage of the fourth order, and their strength is equal to or even stronger than that of ghosts, so they will not be killed in seconds.

Suddenly, all the ghosts near one of the arrow towers erupted into a sharp roar, and the sound seemed to come from the Nine Hells, causing an infinite chill to arise in people's hearts.

At the moment when the roar was issued, the movements of the magicians around the arrow tower stopped instantly, and those ghosts passed directly through these magicians and reached the top of the arrow tower.

This group of ghosts seemed to have taken the lead, and the ghosts in several other directions also began to follow suit, and for a while, there were loud whistles one after another, and the situation on the scene suddenly changed greatly.

Almost all of the mages beneath the tower were in a state of stupor, and the spirits entered the tower unhindered.

Although there is also a heavy wooden door underneath the tower, it is impossible to open this door by conventional means. But for the shadowless spirits, it only takes a tiny crack to get into, and it can't hinder them too much.

Louis rushed over from a distance, and when he saw this scene, his face suddenly changed, and he immediately ordered personnel to urgently mobilize archer mercenaries from the fortress in case of accidents.

It is true that the individual strength of those archers on the arrow tower is stronger than that of the ghosts, but those are all archers, and with the characteristics of the ghosts' physical attack immunity, those archery books cannot cause the slightest damage to the ghosts at all, and it is estimated that it will not be long before those archers will be killed by the ghosts one by one.

Sure enough, when the magicians under the arrow tower woke up from the roar of the ghost and rushed to the arrow tower, the battle inside was nearing the end, and the eight fourth-order early archers stationed inside were all killed.

This is true not only of this tower, but of the rest of the towers.

This is definitely the largest number of mercenaries killed by the North American coalition in a short period of time, and it is definitely enough for the leaders of these forces to feel distressed for a while. Although the mercenaries are not counted as members of their forces, they are hired by them, and if these people are killed and injured too badly, they will have to pay a lot more if they want to hire mercenaries in the future.

Now on these arrow towers, each arrow tower is crowded with at least a hundred ghosts, which is the main reason why the battle can end so quickly, to bite more elephants, not to mention that the gap between ghosts and archers is not as huge as that of ants and elephants.

The mages who rushed up were furious, believing that the archers' deaths were entirely self-inflicted, and that if they could stop the ghosts, they wouldn't have died.

Many of these mages knew the archers on the towers, and some were even friends. After all, many of them were hired from a mercenary camp, and it was normal to know each other.

The angry mages were not relentless, and they used their strongest skills to quickly take out those ghosts......

At the same time as the ghosts rushed to the arrow tower, the undead in the distance also began to launch a general attack, and countless skeleton soldiers frantically pounced on the three fortresses, including many powerful skeleton warriors. As for the masters of the undead clan, they didn't have all of them, because the magic tower still existed, and they didn't want to be killed by the magic tower when they charged.

Without the help of the arrow tower, the pressure on the warriors on the fortress walls suddenly increased, especially those powerful skeleton warriors or black warriors, who even needed mercenaries to attack two or three times before killing. As for the ordinary fighters in the coalition, it is even more difficult to kill the skeleton warriors, and with their reaction speed, it is difficult to even hit the opponent.

In just over ten seconds, the undead at the forefront rushed under the city walls, and some skeleton archers had already begun to suppress the warriors on the city walls from a distance.

"Block! Be sure to block it! The officers on the walls were roaring, and they knew that they could not retreat at this time, for it was impossible for them to build a line of defense like the one they were now.

The North American Coalition has tens of millions of troops, and they will stop at nothing to keep the undead in South America.

At this moment, the death rate of the fighters in the fortress has increased dramatically, and at least hundreds of fighters are dying every second, and this casualty rate is enough to make people despair.

But now the human coalition will not even have the idea of despair, because they do not have time to despair, in their consciousness, there is only fighting, fighting, until the last breath is swallowed.

The battle on the walls became more and more fierce, and at some point there were already undead spirits rushing up to the walls, engaging the warriors or summoners on the walls.

More and more human warriors are dying in battle, but in exchange for the death of the undead cannon fodder skeleton soldiers. You must know that it is the elite of the human side who are dying now, and if this war continues like this, it will only be the human race that will perish in the end. (To be continued.) )
