It has been said that wars are fought in logistics. To put it more bluntly: war is money.

It is also said that the war is fought by intelligence. Knowing yourself and your opponent is the most important thing.

Whatever is right, let's ignore these arguments for now.

Because from the moment he entered the swamp, Roger was clear: he had no advantage at all, both logistically and intelligently.

As living beings, Roger and Mom, as well as the alchemy druid elders, need to eat, drink, and sleep. Although the elemental creatures don't need this, Roger, as the commander, is obviously definitely not comparable to the undead creatures in terms of stamina.

No matter how well Roger prepared the logistics, in this regard, no force dared to claim that it could match the forces of the undead in terms of logistics. The undead don't need logistics at all!

What's more, this swamp is still the other party's territory, and the other party, who occupies the geographical advantage, is obviously more convenient in logistics than Roger and his party from afar.

Roger, who broke into the territory of the undead, is actually completely inferior in terms of intelligence.

Don't look at the fact that he sent out all the thunder elements and storm elements, and the flame elemental, ice elemental, and rock elementals were also constantly probing, but the undead forces with a geographical advantage crushed Roger from the beginning in terms of intelligence.

Unlike the Elemental Legions, which found almost nothing, the Elemental Legions' biggest gain was that the Flame Elemental blew up a few skeletons in charge of reconnaissance when they threw fireballs around.

And Roger, who has been opening the [Eye of True Knowledge], has already discovered more than a dozen "sentry posts" arranged by the undead along the way.

If the few skeletons that sank into the swamp and weren't yet hung up could also be considered sentinels.

Roger said that this journey has really opened his eyes.

For example, the skeleton soldier who was sunk into the swamp and buried, with only one skull hanging from the tree, the burning soul fire in the skeleton was obviously not fake.

The ghosts that also hide in the swamp and pretend to be water ghosts, the bats that have been hiding in the trunks of dead trees in the hollow, and the zombies that have fallen into the mud pond and pretend to be floating corpses......

Almost everywhere you pass along the way, there are sentinels of the undead forces!

Roger really feels that he has learned a lot from the undead, and next time he goes back, he will try to hide the earth element in the ground and the water element in the water to be responsible for reconnaissance.

Since the undead forces knew everything about Roger's elemental legion from the beginning, Roger simply moved forward with great fanfare.

Not to mention the thunder element and storm element flying all over the sky, the flame element that throws fireballs everywhere is the main force! The ghostly class that tried to get close to Roger with the help of the fog was directly knocked down by the flame elements that threw fireballs everywhere, and the actor zombie who pretended to be a floating corpse and stared at this side with big eyes was also blown away by Roger's unceremonious order to the flame element.

Walking vigorously all the way to the depths of the swamp, the rock elements stepped on all the pits that seemed to be formed naturally, and the mud pond that could not be crossed was directly frozen out of a path by the ice elements, coupled with the flying air elements and the flame elements that littered the fireballs, Roger moved forward for two days as if he was afraid that the undead would not know that he was coming.

Then he suddenly died down.

Then on to the reason for Mom's discomfort (in fact, Roger was ready to stop if he didn't), Roger asked the Elemental Legion to forcibly clear out an absolutely "clean" place.

All the undead creatures hiding in the nearby dead trees, swamps, mud pools, and underground were all cleared by Roger.

After ensuring that the large area where the army was stationed was completely devoid of the "eyes" of the undead, Roger began to prepare dinner.

The air elementals are quietly waiting for guests to come to the door.

The enemy army, which had been making a lot of moves under his nose, suddenly fell silent, and hid in the fog that he could not "see", and Roger did not believe that the undead could wait in peace.

The ghost doesn't know if Roger will make any small moves.

If Roger had been replaced, Roger would not have waited so quietly for the enemy to appear again.

But when the crow appeared, Roger, who had been eating curry with his head down, almost squirted rice.

Is there a more obvious hint than the sudden appearance of a living crow in the dead silence of the swamp?

Roger almost looked up to the sky and sighed: he had prepared a lot of small means to detect the enemy scouts who "quietly" arrived, and the other party ran over with such a big grin.

Roger, who was worried that this might be a trap, was truly relieved until the air element quietly followed the crow back to the suspected enemy's lair.

Although the enemy is so stupid that Roger is always a little inexplicably disappointed, it is not in vain that Roger is so fortunate to be able to find a stronghold of the enemy and recover some of the disadvantages in intelligence.

Putting aside this consideration, Roger noticed that the curry rice in his hand was almost cold, and then he took a big bite of dinner.

Due to the overflowing power of the undead, there was not even a living creature in this place, not to mention small insects, so this night, everyone, including Roger, had a rare good night's sleep.

After all, although there are shifts to rest, how can it be possible to rest well on the constantly moving rock elementals, in fact, even Roger is tired enough, just holding on.

In the middle of the night, Tuna quietly got up.

Mom in the same tent slept deeply, completely oblivious to Tuna's movements.

As if fearing that the sound of putting on the armor would attract the attention of the others, Tuna did not put on the heavy armor again, but just walked out of the tent in her thin pajamas.

The surrounding rock elementals who were in charge of guarding did not say anything about Tuna's movements, after all, Tuna was now their immediate boss. Of course, even if she wasn't, Tuna, who was an Earth Elemental Hero, was completely able to ignore these fifth-order rock elements.

However, the other elemental beings in charge of perimeter patrols and air guards did not react to Tuna's departure from the camp, which made Tuna a little confused.

Obviously, Roger doesn't seem to be on guard against Tuna, much to Tuna's baffling.

After all, in the eyes of elemental beings, the Terrans have always been known for their cunning, not to mention that Wendy, the hero of the wind element, is quite at odds with Roger.

Shaking her head, Tuna didn't think much of it and left the camp straight.

At the same time that Tuna left, Roger also closed the system map, scratching his head quite confused, quite puzzled by Tuna's actions.

In fact, among the four elemental heroes, Roger is the most relieved is Tuna, after all, in the mouth of Mum, who has frequent contact with Tuna, Tuna is obviously the kind of "honest" elemental hero.

It's like those hard-working earth elements.

The night passed quickly. In the middle of the night, the undead forces did not seem to know that they had been exposed, and did not take advantage of the night to sneak attack, but just sent some ghost troops to try to approach the camp.

However, the Flame and Ice Elementals had already emptied the fog from the makeshift camp area beforehand, and had also created a reserve area free of fog. At the edge of the range, the Ice and Fire elementals surrounded the entire camp, doing their best to keep the small camp free of toxic fog.

In this case, all ghostly creatures that attempt to pretend to be "lost" and "stray" into the camp are directly shot down by the sentient Thunder Elemental.

The argument that there are ghosts in Roger's hometown is actually plasma. It doesn't matter if this argument is correct or not, but the ghost class that left the fog was indeed knocked down by the Thunder Elemental before the Flame Element and the Ice Elemental.

After nearly ten Ghost classes were wiped out, the undead forces no longer attempted to send Ghost classes to invade the camp.

And near the early hours of the morning, Tuna, who had gone out, also returned.

Under the prompting of the system, Roger quickly dressed in advance and waited on the outskirts of the camp, and was quite surprised to see that the ragged Tuna was carrying a crystal on her shoulder, and she came back unhurriedly.

It was a special magic crystal.

To be honest, Roger was quite moved at this moment.

Just because he wanted crystals, Tuna ran to bring him the entire magic crystal he found by herself, how could he not be moved.

But soon Roger's face became embarrassed, and his eyes were dodgy and did not dare to put it on Tuna's body.

The reason is simple, Tuna may have been attacked by undead forces when she went out, and it is obviously impossible for the magic crystal to be surrounded by those demonic beasts or lost alchemy classes who are attracted by the magic of the crystal.

Tuna must have been through a series of fierce battles, and her pajamas were so tattered that they couldn't cover her body at all.

To be honest, with the white face of Tuna and the tattered pajamas, if there are any more blood stains, at first glance, Tuna may really be regarded as an undead.

Unlike the three elemental heroes, Wendy, who has an electrified body, Cornis, who has a high temperature, and Konia, whose body is close to freezing, Tuna, whose body is closer to the temperature of the human body and does not have those "incidental" special effects, can wear ordinary clothes.

At this moment, the pajamas on Tuna's body should have been given to her by Mom, and the silk pajamas that were originally quite delicate are now completely a rag.

However, Tuna, who was everywhere, obviously didn't understand how tempting her current appearance was, and just tilted her head and looked at Roger with red ears in a strange way.

Although she has become a humanoid and has learned a lot about the daily behavior of humanoid creatures through contact with Mum, it is clear that Tuna has not fully adapted to her new identity.

At first glance, she knew that she didn't feel that there was anything wrong with her almost not wearing clothes, after all, when did the elemental life wear clothes?

His eyes swept over Tuna's face, and Roger, who saw the conspicuous gem and remembered Tuna's identity as a hero of the earth element, could only reluctantly take the magic crystal in Tuna's hand.

As soon as he remembered that Tuna was actually an earth element, and that her body was as hard as steel, Roger suddenly lost all superfluous thoughts. He doesn't have the stupid idea of trying to challenge the strength of steel with his own **, and he's not a sad wind!

As a result, Roger, who didn't catch it steadily, directly missed and let the magic crystal fall to the ground, the magic crystal was far heavier than Roger imagined, and it was not something that ordinary people could move at all, and it was really difficult for Tuna to carry this thing all the way back.

Without trying to move the magic crystal again, Roger directly took out the hero's certificate. Watching the magic crystal turn into countless points of light and be absorbed by the hero's proof, Roger was in a very happy mood after glancing at the "mana +1" prompted on the system panel.

Seeing Roger's smile, Tuna's smiled softly.

After getting the magic crystal, Roger took Tona to his tent, and Tona followed Roger into his room without the slightest doubt.
