Although he was anxious, this time Roger did not rush at full speed, but took advantage of the destruction of the dark canopy and the mist of the swamp had not yet risen again, and carefully investigated the traces of various strategic buildings.

It has been a long time since the undead forces left the Misty Swamp, after all, the army sent by the Church of the Gods directly turned over the entire Misty Swamp, and it is natural that there will be nothing good left.

But now Roger wants to say that maybe the Church's expeditionary force did scrape the entire Misty Swamp at the beginning, but after such a long time, there are still a lot of new good things.

Needless to say, strategic buildings such as lucky springs, fairy rings, and other blessings, relying on Tuna's elemental perception ability, Roger and his party directly found seven special strategic crystals.

Among them, there are two destruction crystals that bless attacks, and there are also two guardian crystals that bless defense, but unexpectedly, there is not a single crystal that blesses mana, but the revelation crystal that blesses knowledge finds three in one go.

Tuna said that the crystals were of little use to her, and that when she returned to the Elemental Convergence Point, there would be a lot of them in a few more years.

So Roger smiled and absorbed it himself.

Maybe these crystals are really useless for Tuna, after all, as an elemental lord, she actually attaches more importance to the improvement of her own strength, but these special crystals are worth a lot of money to Roger, after all, each special crystal is equivalent to an increase in a hero level, and the aura formed by these hero attributes is quite a big improvement for the troops under Roger's command.

With this favor in mind, Roger and his party continued to a strategic building that had just been discovered.

And the witch's hut that Roger had found before that looked like it was poured out of a mold.

But if you look closely, it's a little different, this witch's cottage seems to be decorated with a lot of flowers and plants?

What made Roger a little laughable was that the witch in this witch's hut was actually a fairly young witch, even a young witch.

The little witch, who looked no more than ten years old, told Roger that she taught logistics, so Roger and Tuna honestly learned the essence of logistics by relying on the strange magic book in the little witch's hand.

With a faint glimmer of light from the spellbook, both Roger and Tuna's Heroics have been given a new boost.

Roger directly promoted the first level of logistics, while Tuna learned the elementary logistics.

At this time, Roger noticed that Tuna had also directly increased by two levels after the battle with Archduke Josephine, and the hero attributes added were all defense, and now the defensive aura had reached as many as 21 points, which made Roger shake his head.

And Tuna's two newly acquired secondary skills are Defense's infinite vitality and holding the position, which also makes Tuna's Earth Elemental troops even stronger.

If there are enough of them, you can try to break your wrists with the Rank 8 troops.

When Roger and Tuna finished learning logistics, the little witch cheered and began to pack her things, and Tuna, who had no scheming, asked directly, and the little witch's answer made Roger really cry and laugh.

"Eh! Because of the young age, there are very few indicators allocated, and this year has only opened the hut for two weeks, and someone has come to the door! After receiving the two of you, you can rest for a year! People have long wanted to visit the famous commercial capital of Wickeld! It is said that there are even artists from the Far East! The little witch's milky answer was really speechless, but Roger still honestly followed the instructions left by many seniors and silently took Tuna away.

"Wait until next year, people will open their doors! Be sure to check out the neighborhood when the time comes! The little witch stood in the doorway and waved excitedly at Roger and Tuna, then slammed the door of the hut, and the hut disappeared out of thin air right under the noses of Roger and Tuna.

Pulling the corners of his mouth, Roger left Tuna with three elemental marks nearby, so that it would be more convenient to get up early in the future.

The reason why Tuna made a move instead of Roger himself leaving a magic mark was because Roger's natural magic mark was not guaranteed to be stable for a year later.

The next two witches' huts were much more normal, and the two old witches with deep wrinkles enough to trap mosquitoes wrapped themselves tightly in black cloaks, revealing only the small half of their faces below their noses.

These two times, Roger respectfully took Tuna to learn strategic skills from the witches according to the instructions of his predecessors, I don't know if it was because of Tuna, the elemental hero, the attitude of the two witches was not bad.

At least it didn't turn Roger and Tuna into frogs.

The second witch teaches attack, and Roger and Tuna successfully learn this strategic skill before being blasted out of the witch's hut by the witch.

However, there was a slight accident with the third witch, who taught the mechanics of war. When the witch stared at Roger for a long time and snorted, Roger thought he was going to be turned into a frog or a lamb.

Thankfully, the witch just ignored Roger and taught Tuna the mechanics of war, blasting the two out of the hut.

Roger, who was not subjected to the witch's strange witchcraft, was very relieved, after all, from the classics left by the heroic predecessors in the hero academia of the elven race, Roger most often saw that the witches were unhappy and directly turned the visiting heroic predecessors into frogs.

Even in the form of frogs, the seniors who wore the certificate of heroism successfully acquired strategic skills, but turning into frogs was definitely not a good experience.

After all, there were even seniors who were turned into frogs all day due to the wrath of witches, and the memoir left this sentence: Believe me, eating bugs all day under the instinct of a frog is definitely not a pleasant experience.

Roger, who was frightened by this sentence, did not complain anything even if he was blasted out of the hut by the witches, but Tuna was a little dissatisfied, but was appeased by Roger's good words.

After converging Merina and the air elementals who were not qualified to enter the hut, Roger, who had collected the core of the misty swamp, took everyone straight to the Blood River Castle.

Mom had been waiting for her to see through it.

Seeing that Roger and the others had finally returned smoothly, Mum and the Druid Elders were busy arranging for everyone to rest.

In fact, Roger is the only one who really needs to rest.

As an elemental hero, Tuna said that it would be no problem to fight for two more days and two nights, but the hurricane element and the heavenly thunder element, which had just advanced, needed to replenish enough elemental power, and at this time they were flying into the sky to absorb the free air element.

Melina, on the other hand, took some of the soul dust left by the ghosts, and after it was decided to evacuate, the spirits were all scattered. The resentful spirits that have now belonged to Roger have no room for resistance at all, and directly turn into piles of soul dust.

Melina was treated with Death Knight Geralt's Death Entanglement, but the damaged spirit still needed some soul dust to repair.

Although he was in a hurry to go back, Roger also knew that his state was really not good, so he honestly rested under the arrangement of Mom.

The sleeping Roger didn't even know when Tuna got into his bed, after all, Tuna, who was an elemental hero, exuded completely elemental fluctuations, as long as Tuna restrained that strong elemental fluctuation, she would never be noticed without looking at it.

This can be regarded as "stealth" to a certain extent.

So when Mom came over to call Roger the next day, there was another burst of chickens and dogs.

After appeasing Mom, who was actually just taking the opportunity to vent his dissatisfaction, Roger dismantled the alchemy core of the Blood River Castle and summoned the Elemental Legion to completely demolish the Blood River Castle.

To be honest, Roger was also a little hesitant to demolish this city, after all, after the forces of the vampire family were repulsed, this misty swamp was actually very suitable for building a city, after all, the natural defense line of the swamp and the various resources here can be said to be very good for the Emerald City and even the elves.

However, even the elven royal family did not have the capacity to build here, and Roger, after careful consideration, also directly demolished the Blood River Fort.

With the Elemental Legion as the backing, Roger could actually try to build a fortress-type city in the Misty Swamp, but the location of this Blood River Fort was obviously not suitable, so Roger simply demolished it.

Having gathered all his troops, Roger opened a portal in time and space on the ruins of Bloodriver Castle.

This kind of strategic magic was specially set up by the gods to assist the alchemy troops after setting up the alchemy city, so only heroes can use it.

Opening such a space gate itself requires a lot of strategic magic, and maintaining the space-time gate while the troops pass through also requires continuous consumption of strategic magic, which also makes the space-time gate a strategic magic that is not usually used passively.

After all, if you choose to open a gate of time and space to teleport tens of thousands of troops, it is enough to drain the strategic magic of a top-level French hero, unless there are other heroes leading the team, otherwise a French hero who has lost all his strategic magic is simply delivering food to the enemy.

The number of Elemental Legions under Roger's command was already small, and after a series of battles, there were only less than five hundred elemental soldiers left, and all of them soon passed through the Gate of Time and Space.

On the other side of the Spacetime Gate is not the Emerald City, but the Frontier Fortress that Roger passed through here in the first place.

After all, in order to prevent the invasion of the demons who are good at raiding by teleportation, the elves have set up many spatial anchors for interference and teleportation in various fortresses and cities on the border, and they are likely to be directly lost in the spatial turbulence if they teleport directly into the elf territory.

Through the solidified spatial fluctuation detection array, the middle-aged elf sentry who had already discovered the arrival of Roger and the others was really relieved to see that it was Roger and his party who appeared from the portal.

At this time, if the undead forces attack, it will definitely be a big bad news for the elves.

Roger asked Mu Mu to take out two alchemy city cores of the undead as proof to inform the news that the elven undead forces had been exterminated, and after he himself passed the level with the elemental legion, he began to prepare for the gate of time and space non-stop.

Even after entering the level, in order to prevent him from accidentally getting lost in the spatial turbulence, Roger still carefully sensed that he had a spatial anchor outside the Emerald City in advance, and relied on the dual positioning of this anchor point and the urban core of the Emerald City to open the door of time and space again.

After recording the experience of Roger and his party with the recording crystal, the middle-aged elf sentry who handed over the core of the alchemy city to Mumu looked at the elemental legion that was quickly passing through the gate of time and space, still a little incredulous.

"With just such an elemental army, we have wiped out the undead forces that can build a large dark canopy, when did such a great Terran druid hero appear in the elven realm?" The middle-aged elf sentry who hadn't been back to his hometown for ten years was really surprised.

After all, even with the alchemy city core of the two undead forces, he still couldn't believe the news.
