In fact, Roger wanted to take the Elemental Legion to the swamp, not only to test the strength of the Elemental Troops, but also to take all aspects into consideration before finally deciding to take the Elemental Legion into battle.

As elemental beings, the four elemental classes are all excellent soldiers like undead creatures, and do not need to eat, rest, etc., which is quite critical in swamps where supplies are difficult to obtain.

The reason why the undead creatures chose to haunt the depths of the swamp is also because they have a fancy to this natural barrier.

However, I remember that the undead clan that was originally established in the depths of the Swamp had already crossed the ocean to the Far East on the other side of the sea due to the threat of the expeditionary force of the Church of the Gods. The expeditionary force of the Church of the Gods, which had almost failed to return, swept through the entire Everglades, but finally returned with only a few heads of the Death Knight heroes responsible for the severed aftermath, which was very big news at the time.

Could it be that another necromancer crossed the sea to the Everglades and built a city of the dead? Or are there remnants of undead creatures who escaped the encirclement of the church in the first place and rebuilt the undead city? Otherwise, it would not be possible to explain the reduction in the production of medicinal herbs that affected such a wide range.

The lack of information made Roger really unable to judge, so he could only take one step at a time.

In order to ensure the security of the territory, the elves relied on fortress cities such as Shenmu City and Luye City on the border of the northern misty forest, and established a green defense line. In the east, a defensive line has been established on the edge of the swamp, and it is quite difficult to attack the elven mainland from the swamp.

In the middle of the two lines of defense, at the gap in the northeast, that plain is not only guarded by many elven sentries day and night, but also the border city of Danrad guarding there, not to mention the free federation led by the mercenary kingdom, an ally of the elves.

Although most of the slave catchers in the northern Wolf Principality leaked from this side, there have been no large slave catchers who have been able to pass through this line of defense, and there are not even many small and medium-sized slave catchers.

The civilians of the elven race are still very relieved about this green line of defense.

However, if the traces of the undead in the depths of the Everglades are true, then the elven royal family and elders will have a headache.

The traces of the drow elves in the north are true, after all, counting the time, it is also the plundering season of Queen Rose, and at this moment, the defense line in the north must be ready for it.

And if there is an undead attack on the eastern defense line, although the elves facing a two-front battle can still grit their teeth, the elves who are tight on the army will have no troops to deal with emergencies.

In case the demons run out at this time, it is not impossible for the whole line to collapse, and it is no wonder that the goddess of nature will personally issue an oracle.

However, crises often represent opportunities, if Roger can rely on the Elemental Legion to solve this undead invasion, such a great achievement is also difficult for the Elven Royal Family, and the Elven Royal Family's solution is probably only to directly recognize Roger as the new prince of the Elven Race.

After all, until now, Roger's relationship with Luna has never been able to obtain positive recognition from the elven royal family. Luna doesn't seem to mind, but as a man, such a small thing is of course for Luna.

There's no girl who doesn't want a big wedding.

Thinking in his heart, Roger cheered up and carefully inspected the elemental troops.

Although they are all elemental legions, the form of elemental creatures is not necessarily in the first place, and the strength of various elemental creatures is also uneven.

Compared to the elemental heroes who have already touched the origin of the elements, the more abnormal the form of the mid- and low-level elemental troops, the stronger their strength is.

The strength of the sub-elements of the ice element and the thunder element is much stronger than the ordinary water element and wind element, such as the sea element, the storm element, the flame element, the lava element, etc., which makes Roger even more dazzled.

However, after thinking about it carefully, Roger smiled a little wryly.

Tunotuna seems to have really enjoyed the work of a guard lately, and spends her days with Mum following Roger. Then as the direct force of Tuna, the subhero directly under Roger, a large team of earth elements is obviously necessary.

The relationship between Wendy of the Wind and Roger has not been good, and this can be ignored. After all, when it comes to the battlefield, a hero who keeps giving orders is originally a powerful hostile hero, which is very harmful.

This is probably the otherworldly version of a god-like opponent who is not afraid of a god, but a pig-like teammate. Roger really smiled bitterly in his heart.

The water elemental Cornia and the fire elemental Gonys are unexpectedly good friends. It is said that because Gonis, who is a fire elemental hero, is not able to control the flames on his body freely, and the temperature of the elemental fire on his body is so high that he can easily melt the rock armor of Tuna, and directly ignite the body of Wendy of the wind. The other elemental creatures who were also fire elementals did not dare to approach due to the coercion of the high-ranking elemental creatures on the fire elemental heroes.

That's why Cornis, who can't get in touch with other elemental heroes at will, becomes good friends with Konya, the only one who is not afraid of her elemental fire.

Because of this, these two heroes often go in and out together, and if Roger chooses one of the elemental heroes, the other elemental hero will follow. But Roger wasn't going to take too many elemental heroes with him, so there would be no point in testing.

The Hero's Evidence can bless up to seven troops and have seven sub-heroes at the same time, and it is not impossible to bring more troops, but without the blessing and control of the hero's aura, the alchemy troops are easy to encounter various non-combat losses: for example, when the troops without direct control are in the army, they lose contact because they get lost and become directly lost and so on. The frequency of these bizarre losses has made the hearts ache of all heroes who have tried to "super-compile".

In fact, Roger has tried to use the Hero's Evidence to command the troops, this way of directly transmitting orders to the minds of every unit in the same unit is convenient, but the information that can be conveyed is quite simple, and there is a limit on the number of orders in a certain time, and the same unit can only accept two orders in three minutes.

It's enough for ranged troops, but it's still quite troublesome for melee troops, especially high-speed units such as cavalry that need to be moved back and forth frequently.

Therefore, Roger generally tries to use "thousands of miles of voice" to give orders. However, when commanding a large number of troops, such frequent use of teleportation magic can also cause a considerable burden on Roger, who has not yet reached the legendary level.

Now Roger plans to try to combine the two, usually using the Hero's Credential to give orders to the troops, and the "Thousand Miles of Voice" is reserved for emergencies.

Considering that this time he was dealing with the undead troops, Roger planned to bring six official troops with him.

Led by Tuno Tuna and Mum a hundred fifth-order rock elementals as guards.

Rock elements

Race: Elemental

Rank: Fifth Order

Class Traits: Earth Immunity, Infinite Counterattack, Magic Resistance, Regeneration, Heavy Punch.

Perhaps the rock elemental's attack power is not as high as the lava elemental, but the reason Roger is quite interested in it is that the rock elemental has a passive ability that can stun the opponent it hits.

With punches that stun and infinite counterattacks that can counter all melee attacks, this is undoubtedly a class that is not afraid of siege.

The ranged troops are composed of two Flame Elemental troops, one Ice Elemental Unit, and one Thunder Elemental Unit, each of which is also numbered a hundred.

Flame elemental

Race: Elemental

Rank: Fifth Order

Class Traits: Marksman, Fire Immunity, Flame Shield, Incendiary Grenade.

Ice elemental

Race: Elemental

Rank: Fifth Order

Class Traits: Caster, Water Immunity, Ice Bullet.

Thunder elemental

Race: Elemental

Rank: Fifth Order

Class Traits: Marksman, Flying, Air Immunity, Electric Shock, Wind Shield.

The flame elemental incendiary grenade can ignite the undead troops, and when the undead troops are burned until they fall without leaving a corpse, the undead army's undead resurrection tactics have no basis to be used.

Cryo's ice projectiles can freeze the troops hit, and although they are not for a long time and have a chance to be exempted, they are still very effective in control.

As the only airborne unit, the Thunderbolt Elemental is also a powerful unit that can throw lightning in the air and attack the enemy from a distance, which is the focus of Roger's test this time, and its lightning throwing ability and passive electric shock effect can make the Thunderbolt Element cause a lot of damage in a small area. If the performance of the Thunder Element is qualified, then the Thunder Element will become the main air force unit of the Emerald City in the future.

Of course, the tested air class is not only a thunder element, but also a storm element, Roger, is also quite optimistic.

Storm Elemental

Race: Elemental

Rank: Fifth Order

Class Traits: Flying, Air Immunity, Storm Guardian, Wind Bondage, Wind Shield.

Compared to the Thunderbolt, the Storm Elemental does not have the ability to throw lightning, but it does have the passive effect of Storm Ward, which reduces two stacks of ranged damage, while Wind Binding slows down the movement of the hit troops, and makes it difficult for the ranged troops to attack.

These two air force units, one near and one far, and each with its own special effects, really made it difficult for Roger to choose, so he simply brought them out together.

If it's a mule or a horse, you'll know it.

Looking at the small army composed of six hundred elemental troops, Roger was still a little excited. After all, it was the first time he had commanded so many troops.

What's more, the Elemental Legion is all up to the fifth order, and it may not be too strong against the top class of the eighth order, but if it is a sixth or seventh order, with the advantage of numbers and various special effects, it is enough to make the enemy deflated.

Well, no, the Death Knight, the seventh-order class of the undead class, is even more impressive than the eighth-order bone dragon.

If you really run into a death knight, even an eighth-order class is very dangerous.

After thinking for a moment, Roger asked the Druid Elders, who had not planned to be dispatched, to join his command. At this time, Roger noticed the look of dissatisfaction on Ina's face.

"Have you awakened?" Roger was a little surprised.

Ina gave Roger a blank look, and quietly stood behind Roger with Roger's flag, standing with Mom and Tuna.

Roger couldn't help but smile wryly.

"Oh, Lord Jack! Finally found you! A dwarven warrior ran to Roger out of breath, "Grand Elder Ouattara heard that you were preparing to go on an expedition, so he asked me to bring you such a thing. ”

The dwarven warrior took out a crown, and Roger took it, and the dwarven warrior immediately turned and left.

Roger looked closely at the crown in his hand and saw that it was a strategic treasure, and the kind he lacked the most right now.

"A strategic treasure, the crown of wisdom."

"Effect: Light of Wisdom: +4 knowledge for the equipper."

"This crown will fill you with wisdom."

Putting on this [Crown of Wisdom], he habitually changed his appearance with camouflage magic. With this treasure, Roger has more confidence in this expedition.

"I owe a favor." Roger touched the crown on his head, a little helpless.

PS: Customary recommendation! I don't have half of the collection, and I'm drunk.
