After leaving the forest, what you can see is a basin topography that extends diagonally downward, the bottom of the basin is flat, and a wide river meanders through the basin, nourishing the water and grass along the banks of the river are fertile and lush.

In such a rich grassland, you can see groups of animals running, especially those wild pegasus, when their white bodies gallop in the grassland, like a swimming white line, very obvious, and when they are tired of running, the pegasus will collectively spread their wings and fly into the sky, hula la occupy a large airspace, frightening those lonely wild griffins to dodge in a hurry, and then angrily roar towards them in protest.

Some low fruit trees are scattered scattered on this grassland, and the berries produced on the trees attract some small animals to come to feed, and these small animals also attract predators to attack and ambush, and on the banks of the river, there are a large number of large animals such as antelope and bison to drink, they are cautiously alert to the possible presence of crocodiles in the river, and they will raise their heads to observe the surroundings every time they drink.

Countless flying insects, butterflies and bees flutter over the flowers in the grass, startling other animals when they pass by......

This is a place full of life, and Roy, who had just come out of the desert of death, looked at this scenery with some surprise.

"It's a nice place!" Roy said: "I can't tell what kind of border area it is. ”

"Master, the fortress is there!" Kassandra had fallen to the ground by this time, and she pointed ahead, "Just follow the river." ”

Roy looked up and saw that the meandering river stretched all the way forward, and after crossing the basin grassland, it gradually converged into the interior of a wide canyon, which was surrounded by cliffs on both sides, and above the cliffs, a huge city was embedded in it!

The fortress is at least a few dozen kilometers away from here, so it looks quite small, but Roy assessed it, at least it is a large city that can accommodate about 100,000 people, even if you look here, you can see the high smooth city walls on the periphery of the city, if this city is about 100 meters from the foundation to the top of the city, then the walls around the perimeter of the city are at least fifty meters high!

This fortress built on the cliff is equivalent to firmly guarding the entrance to the canyon, and any ground troops who want to pass from the canyon to the Iorfu realm will be discovered by the fortress, and above the fortress city, Roy saw countless dense flying black spots, which are gargoyles patrolling day and night, and a small number of griffons and green dragons are mixed forces.

However, judging from the main direction of the city wall, Roy found that this fortress may be mainly aimed at the interior of the canyon, that is, the precaution is just the direction from which it comes, and it seems that after the demon army has gained a foothold in the Ioufu realm, it has really made the nerves of all races on the continent tense, for fear that when the demons will rush out again.

After observing for a while, Roy found that the flying troops flying over the fortress were replacing them regularly, indicating that the fortress was just on routine alert, and the elven rangers killed in the forest before did not transmit the information back to the fortress, otherwise, it might not be such a scene.

Roy sensed the location of the demonic eyes he had unleashed earlier, and saw that they were already approaching the vicinity of the fortress and were on standby.

"This is the fortress city of Dendra set up by the Kingdom of Bradaca!" Giovanni introduced in a loud voice: "Another elven fortress Agran is on the other side of the canyon, these two fortresses are large fortress cities with more than 100,000 people, even if the demon army wants to fight out, it will have to pay a great price, with all due respect, Lord Osiris, it may not be a good idea to attack directly." ”

"I'm not stupid!" Roy glared at Giovanni and said, "You don't want to look at how many troops I have, the vampire troops you promised to support haven't seen yet, so why should I use such a small number of troops to attack such a fortified city?" ”

After being scolded by Roy, Giovanni shut up stupidly, and Juliel asked next to him, "So what are you going to do?" Will there be another dark snowfall? ”

Roy shook his head and said: "It's useless, it's different from using it in the forest, there must be a large number of magicians in the fortress city, once the dark snowflakes fall, they will immediately find out that something is wrong, and then those magicians will have a way to get rid of these snowflakes, so that not only will it not have any effect, but it will expose us." ”

What Roy said, Juliel actually understood, but she really couldn't figure out what kind of method Roy should use to conquer such a fortress city, even if Roy was strong enough, Juliel was also a high-ranking demon, and Fat Tiger, Giovanni and Kassandra were assisted, and they were also helpless in the face of such a large number of troops.

"Otherwise, let's set up a summoning array here first!" Juliel proposed, "Open the door to the abyss, and even if it is a little simpler, we can summon a lot of demons." ”

"Don't worry, the demon army will definitely summon it, and if it does, it's best to make a larger abyss gate!" Roy grinned and showed a hideous grin: "But not now, when we have a stronghold, the demon forces will be used against Serren at that time!" Now I have a better way to storm this fortress. ”

Seeing that Roy was so confident, Juliel didn't ask, and Roy himself first controlled those invisible demon eyes, and began to cautiously approach the fortress Dandra and began to conduct close reconnaissance.

In fact, with Roy's current quasi-lord-level strength, it is not impossible for him to destroy this fortress city alone, but it is foreseeable that in such a fortress city, there must be a large number of leading heroes stationed in it, and those low-level troops may be okay, but those high-level combat forces such as the Green Dragon Titan, under the leadership of the leading heroes, may cause huge trouble to Roy.

When fighting with Arrantiel, Roy understood that the characters who can be called heroes in this Yashan world basically have the strength of not weaker than the average high-ranking demon, and even some famous heroes with great achievements are stronger than the higher-ranking demons.

Even Roy had to be glad that this was not the fortress of the Kingdom of Erathia, otherwise, there might still be a large number of angelic troops, and for demons, the angels were more difficult to deal with than the dragons and titans.

As the Demon Eye approached, the situation in Dendra City gradually revealed itself to Roy.

The reason why it is said to be a fortress city is because there are no civilians in this city, and almost all of the troops in the city are deployed, and it is estimated that the Kingdom of Bradaka is also worried that in case of a demon invasion, it will be difficult for the civilians in the city to evacuate, so they simply stationed all the troops in it.

In this fortress, you can see iron golems moving neatly everywhere, and the number of these iron golems is estimated to be the largest, at least about fifty or sixty thousand, and everywhere in the city, you can see the factory workshops that make iron golems, and a large number of goblins shuttle through it, building and enriching the golem troops according to fixed drawings.

On the city wall, there are a large number of mage towers and crossbow cart embratos, as well as a large number of catapults and other equipment, which are used for defending the city, Naga snake demons with scimitars patrol the passage of the city wall, and some elven rangers who have come to support the elves are carrying longbows and stomping between the bricks of the city wall to look out.

A little further inside, there is the interior hall of Dandra City, where there are hundreds of Titans guarding it, including the Lightning Titans with lightning entwined in pitch black, and the Storm Titans entangled in hurricanes, they are the most powerful force in this fortress.

The Titans and the Dragons have never been on the right path, and they don't like each other, so some of the green dragons and emerald dragons supported by the elves don't bother to go to the center of the city to deal with the Titans, and these green dragons and emerald dragons either fly up to the sky to patrol, or occupy the top of some buildings in Dendra City, lying on them with their wings folded to rest.

The gargoyles would not come near the dragons, and even the few griffons in the city that were used to deliver messages and letters could bully them, but these gargoyles were arguably the most industrious and loyal troops, working tirelessly day and night to follow the orders given by the mages, and to monitor any movement in the canyon while the griffons and dragons rested.

When the Demon Eye transmitted this scene back, even Roy couldn't help frowning, under normal circumstances, if you want to take down such a fortress, you need at least twice as many troops to be possible.

Roy controlled the Demon Eye to fly towards the location of the Internal Affairs Hall, because he was worried that he might be discovered by the Titans, Roy deliberately raised the height of the Demon Eye, and then he saw through the Demon Eye that there were many heroes who appeared to be heroes, coming and going in the government affairs hall from time to time, just for a short while, the number of people who were suspected of being heroes found by Roy was six or seven.

And at the back of the House of the Interior, Roy finally found what he was looking for.

It was a silver arch, made of all metal, it looked about four or five meters high, very huge, this metal arch was placed on the ground, connected to a large area of magic array on the ground, each stripe of the magic array emitted a faint light, and on the periphery stood more than thirty magicians with magic staffs in their hands, they seemed to be providing magic power for the magic array and the metal arch.

And in the center of the arch, a large white vortex of light was slowly turning......

This should be the space portal, such a huge space gate that can be used to teleport troops, it is quite difficult to set up, and it costs a lot of money, but with it connected to another elven fortress Aglan, the forces of the two cities can be communicated, that is to say, if this space portal is not removed, Roy will be equivalent to fighting two fortresses at the same time, which is simply impossible.

Roy didn't rush to let the Demon Eye get closer, because he didn't know if there would be something similar to a magic shield in the location of this spatial portal, and if there were, even if the Demon Eye was invisible, flying over it might crash into the shield and be discovered.

Once the location was confirmed, Roy controlled several Demon Eyes to search for the city, and soon found what he was looking for most.

That's a mouthful...... Deep well!

Although the city of Dendra is located on the bank of the river, the people in the city cannot go to the river to get water, and the possibility of the city being besieged must be considered, so it is necessary to have well water like this, and the Bradakas and elves are not undead, they also need water to sustain their lives.

After discovering the water, Roy smiled, remembered the locations of several of the city's major deep wells, and sent the Demon Eyes back.

"Alright, let's wait for now!" Roy said to Juliel.

"What are you waiting for?" Juliel was puzzled.

"Wait for the evening!" Roy gathered his wings behind his back and found a rock to sit down on so that his tail could hang as well......
