The Invincible Overlord of Heroes.

The continuous flares left the undead with no chance at all.

During the day, the fearless skeletons couldn't even get close to the walls of Shenmu City. At night, the undead directly dispatched the vampire troops, one of their trump cards.

Although the strength of this vampire army is not top-notch, it is not bad either.

At the very least, they all have titles, and there are quite a few vampire counts.

After realizing that they couldn't launch a sneak attack, the undead obediently withdrew all the vampires. After all, the flying troops of humans and elves had not moved yet.

There was another long pause, and the undead did not move any further during the entire first half of the night.

Lena had no choice. The biggest advantage of the undead was that they didn't need to rest, but humans and elves couldn't do that.

If the soldiers are not arranged to take turns to rest, they will be truly trapped by the undead.

Of course, if they rotate to rest, it is inevitable that half of the players will not be able to enter the defensive position.

In the second half of the night, the undead launched another attack on Shenmu City.

This time the attack was still launched from the air, but instead of using vampires, a large number of ghosts and spirits were used.

The biggest feature of ghost-type undead is that they have extremely strong immunity to physical damage.

Even a level 3 ghost has a 50% chance of being completely immune to physical damage.

There are also gains and losses. Ghosts need to bear additional spell damage, especially fire spells, which will cause an additional 50% damage to ghosts.

Moreover, the health of a level 3 ghost is too low, and it cannot withstand the long-range attacks of a high-level shooter.

The undead simply gave up on the level 3 ghost and sent out the level 4 ghost and level 5 spirit.

In addition to having extremely strong physical immunity, these two things also have powerful life recovery abilities and close-range group attack capabilities.

Although the ghost's attributes are not as good as those of a vampire, it can rely on its strong physical immunity and pose a much greater threat than a vampire.

In Shenmu City, the main magic output is only priests and druids.

These people, in total, number only over a thousand, and if they take turns to rest, there are only over 500 people on duty.

The magic output of more than 500 people has high damage, but it is not enough to block the entire sky.

As for the magic shooters, they are not professional mages and have limited mana.

The battle during the day had consumed too much mana, and Lena had basically arranged for them to rest.

Of course, the elves are not without solutions, they just need to deploy some high-level troops.

Before the high-level undead soldiers appeared, our side had already fallen into a disadvantage by using high-level warriors first.

The 20 fairy dragons left behind by the elves demonstrated their amazing magical skills.

It's not an exaggeration at all. Compared to high-level spells that consume a lot of energy for high-level mages, these purple dragons can use them as easily as drinking water.

For example, they can use spells of level 4 or above, such as Chain Lightning, Hellfire, and Ice Storm, continuously.

The only embarrassing thing is that they might use several high-level spells in succession.

But it is also possible to release several fireballs, lightning bolts, etc. in succession.

It's not that this spell has no effect, but killing a ghost with a fireball is just like sprinkling water to an unknown number of undead.

Even if one is thrown out, it can electrocute hundreds of ghosts. The chain lightning of ghosts is not a big threat to the undead.

However, Zilong's mana is terrifyingly high, and his recovery speed is amazing, especially under the protection of the World Tree.

Especially this kind of naturally grown fairy dragon, one can be used as at least dozens of high-level wizards.

The residence that the elves arranged for Xu Lai was a tree house that was not luxurious but was extremely exquisitely decorated.

But to be honest, Xu Lai was not in the mood to have a good rest at all.

The attack of the undead also concerned Xu Lai. He had been paying close attention to the ghost army in the second half of the night.

Only after he was sure that Reina and the elves were not in any danger did he fall asleep peacefully again.

However, not long after Xu Lai fell asleep, Cuisli's subordinates discovered the undead wizard who had been hiding in the dark sky and casting spells.

But this necromancer had an extremely strong perception ability, and the elves were immediately sensed by him as soon as they discovered him.

The necromancer immediately attacked several rangers, even though these rangers were veteran rangers who had experienced hundreds of battles and life and death situations.

But once locked onto by the undead wizard, he still couldn't escape.

Fortunately, these rangers are not vegetarians.

Although not all of them escaped in the end, two of the five rangers in this team still managed to escape thanks to the selfless protection of their teammates.

These two rangers brought the most crucial information to Xu Lai and the elves.

Just as Xu Lai expected, this undead wizard who could throw bone spears across a distance of thousands of meters was indeed an undead king.

However, this Undead King who claims to be the Undead King Sandro is not Sandro.

He is another undead king, Mordor, known as the Undead Lich.

As the king of the undead, Modo is the lowest among the four kings.

Rather than saying that he is one of the four undead kings, it would be more accurate to say that he is Sandro's personal thug.

Because Modo’s specialty is corpse wizard.

In Modo's hands, the corpse wizard, the corpse wizard king, can exert even more powerful power.

It just so happens that Sandro, who possesses the divine weapon, can mass-produce corpse witches.

However, although Modo is at the bottom among the four kings, he doesn't seem to have any famous artifacts on him.

But he himself is actually a lich with great strength and attainments.

The key is that this guy is extremely cautious. Once he finds any danger, he will immediately retreat.
After the rangers brought back the information, the undead, who had been trying continuously, decisively gave up their attempts and attacks, and all disappeared into the dark sky.

“Undead King Sandro, so far, no one has ever seen him take action.

However, it is said that the undead lich Mordor's attainments in undead magic are even better than Sandro's.

Besides, Mordor is one of the four kings after all, so there is no need for him to use the name of Sandro."

Trisley said in confusion.

Xu Lai stroked his chin and said, “It’s obvious that this group of undead must be plotting something.

Since they are using Sandro's name to confuse us, Sandro himself must be doing other things.

Whatever Sandro wants to do, we'd better not let him do it."

"But we don't even know where Sandro is, how can we stop him?" Giselle asked puzzled.

"Is there any way to dispel the dark sky outside the city?"

Xu Lai did not answer Giselle's question, but asked another irrelevant question.

Cui Sili frowned and said, "The Dark Sky Curtain mainly relies on the smoke it emits to cover the sky. If you want to dispel the Dark Sky Curtain, there are two ways. One is to use wind magic to blow away the smoke.

Inside Shenmu City, there are three druids who are proficient in air magic and can cast gale spells to blow away the smoke.

However, the dark sky continued to erupt, and even with the use of the Gale Technique, it could not be maintained for too long.

Another way is to find the Dark Sky's launcher and destroy it.

Without the smoke-emitting launcher, the dark sky would naturally no longer exist.

Yesterday during the day, my ranger team had already found several Dark Sky launchers.

However, this device is located in the undead camp and is guarded by many powerful undead.

Moreover, these installations are large buildings, and it is difficult to destroy them in a short period of time without using siege weapons.”

Obviously, the rangers had already tried it long before Xu Lai cared about this issue, and it was a failed attempt.

The dark sky of the undead is basically unsolvable for the elves.

Read the error-free version at 69shuba! 6=9+shu_ba is the first to publish this novel.

Long-range troops such as Rangers, especially when their numbers are unlikely to be too large, really have difficulty causing any damage to buildings.

In order to destroy the dark sky, the elves can only give up the advantage of city defense and choose to fight the undead in the field.

And this is exactly what the undead want. After all, the elves' long-range ability is well known, while the undead's long-range ability is a weak point.

The Undead's ranged troops, the Skeleton Archers are half-crippled, perhaps even inferior to the Goblins.

The only one that can be put on the stage is the corpse wizard, but the basic level of this thing is too high, and it is difficult to increase the number.

Even though Sandro can convert a large number of corpse wizards with the power of the artifact, this thing is a long-range magic after all.

The range of magic long-range shooting is far inferior to that of physical shooting, not to mention that the elves have the advantage of city walls.

But if they could use a dark sky to lure the elves out of the city, the undead would be able to take advantage of their huge numerical advantage.

The elves had suffered so many losses in field battles that their morale had long been crushed. Now, they had a completely laissez-faire attitude towards the Dark Sky.

Xu Lai slapped the table and said, "It's good to have the undead guarding us. I was just worried that I couldn't find them.

Reina, you don't have to go, just stay and guard the city, I'll take the people there."

The undead's three attempts were all repelled by long-range forces.

Reina's defensive skills and Xu Lai's god-level offensive skills have not yet been demonstrated.

Of course, Xu Lai had to lead the team out personally, not to show off his god-level offensive skills, but to prevent the undead from making a feint to the east and attacking in the west.

After all, the undead wizard Sandro has not shown up yet.

The rangers who went deep into the dark sky to investigate also reported that they found no trace of the Bone Dragon Legion.

This thing is a high-level flying unit. If it wants to launch a surprise attack on Shenmu City, it can do so at an extremely fast speed.

With Reina around, even if Sandro dared to launch a sneak attack, he might not be able to gain any advantage.

"How many people do you plan to take with you? To be honest, the wilderness is more advantageous for the undead. I don't think the Dark Sky is worth your risk."

Xu Lai wanted to go out of the city to fight, but the first one to disagree was the elf who invited Xu Lai to come.

Both Cuisili and the elf elder Yin Mu expressed their opposition.

If something unexpected happened to Xu Lai, given the current state of the barrier, it would most likely not be able to withstand it.

Xu Lai waved his hand and said, "I'm not heading for the dark sky.

And I won't bring too many people with me. I'll go there quickly and come back quickly. No one can stop me, not even the Lord of Hell, Kerrigan!"

Xu Lai looked around and found that all the elves were avoiding his gaze and no one dared to look him in the eye.

As the king of the human kingdom, he naturally has no subordinate relationship with these elves.

The elves' behavior is entirely due to their own guilty conscience.

Being constantly defeated by the undead had already made this group of elves desperate and fragile.

If the World Tree wasn't so powerful, these elves would have collapsed long ago.

On the other hand, Xu Lai and his men have never been defeated in a battle so far, and the undead are just chickens and dogs.

Once Xu Lai has made up his mind, no one from the human side will stop him, and no one from the elf side can stop him either.

He didn't bring too many people with him, just over a hundred of his own personal knights, plus the Angel Legion and Elvy, totaling less than a thousand people.

Xu Lai didn't even bring the royal griffins.

With the presence of vampires, as long as your defense is a little bit low and can be broken, your life will be sucked away by them and you will become a blood bag.

Besides, although the Royal Griffin is quite fast and can fly, it is still a burden to Xu Lai and the knights.

Instead, he only brought knights and angels, and they really could come and go as they pleased.

However, in addition to the knights and angels, Xu Lai also brought a few more people, namely Cuisili and her team.

There was no way. Although the rangers had drawn a detailed map, it was actually based on their memory of the forest.

According to what the rangers said, as long as you enter the area covered by the dark sky, your vision will become completely dark.

Even people with dark vision can't see clearly when they enter, let alone far.

Without darkvision, it would be pitch black inside, and you wouldn't be able to see anything.

This is also the main reason why Xu Lai is unwilling to bring too many people.

There are too many people with him, and even if Xu Lai has dark vision, he can't take care of too many places.

If someone falls behind for unknown reasons, it would take a lot of time to find the team.

It is also because of these shady dealings that humans who are completely unfamiliar with the forest are completely in the dark even if they have a map and don’t even know they are lost.

Under the leadership of Cuisili and the rangers, Xu Lai and his knight guards marched into the pure black sky in a mighty manner.

The conspiracy was indeed the same as the rangers described. Even in the dim light environment of the dungeon, Xu Lai could see it clearly.

In the dark sky, even for him, it was difficult to see things more than 50 meters away.

This is very rare for Xu Lai, whose physique has been greatly enhanced.

Xu Lai's performance was considered relatively good. Elvy and the others, who only brought night vision goggles, could only see the situation within a dozen meters around them at most.

On the contrary, the undead have no vision at all. They don't see with their eyes at all, so they are not affected at all.

Fortunately, Xu Lai brought rangers with him, and all of these rangers were able to do it without using their eyes to see.

Using only their ears and their familiarity with the forest and the cover of the plants in the forest, they could lead Xu Lai to any place he wanted to go without any mistakes.

Unfortunately, although the rangers are powerful, the undead do not seem to want to see Xu Lai rampaging in their territory. (End of this chapter)
