Legend has it that the Gray Orcs were not native to the Angry Flame Plane. Their ancestors seemed to come from other places. The Gray Orcs also came from other places. They have only lived on the Angry Flame Plane for countless years and have developed to the present No one in the other Orc races of the Raging Flames feels that the Gray Orcs are aliens.

The fortress in front of it clearly did not match the style of the orcs. Their fortress was a neat square.

From a distance, the city walls look like they are cut from a huge piece of graystone. The city walls are also glittering with the luster of metal plates, and there is a wave of magic wave spreading. It can be clearly sensed several kilometers apart. .

Lin Yun couldn't help but be a bit surprised. The inside of the city wall didn't know what materials were stacked, but the outside was covered with a layer of magic metal forging.

And each metal plate is covered with a small alchemy array, dense patterns, combining powerful defense effects.

And after this gray metal plate is combined, a huge alchemy array will be formed. This city wall is a huge alchemy array. The defensive effect brought by it is very terrible. Spells below level 6 Fall on the surface of the wall, don't even think of any effect.

And you can see that there is a huge and weird alchemy urn standing on the wall, which looks like a huge magic crystal cannon with long legs.

Sure enough, when the fleeing gray orcs entered the fortress, there were violent magic fluctuations on the huge alchemy urns on the wall. It can be clearly sensed from a long distance.

In the huge muzzle like a magic crystal cannon, the dazzling flames began to converge, five seconds later. With a loud noise, a huge fireball with a diameter of more than ten meters blasted out and blasted towards the chasing army of alchemists.

Each alchemy urn blasted a huge fireball with a diameter of more than ten meters, and fiercely hit the ground hundreds of meters away in front of the fortress.

Rumble ...

As if the thundering sounded and the earth began to be lifted up, a huge ditch ran across the front of the Alchemy of the Blade.

And just when the alchemists started casting. Lin Yun had let the mage army and the alchemist army stop chasing.

If not, these few huge fireballs. Can destroy at least a dozen blade alchemists ...

"Master Merlin, what do you do now?"

The off-duty glanced at Lin Yun with a sorrowful look. The gray orcs were too brittle. I accidentally shot it ...

Lin Yun waved his hand.

"Fence around ..."

As soon as Lin Yun's words fell, the team's alchemy urn and grey orc appeared on the metal-like wall on the opposite side.

The surface of the tall city wall, like a mirror surface covered with patterns, also exposed black holes, and a strange alchemist like a magic crystal cannon protruded from the hole.

Suddenly, a large number of gray orcs on the city wall began to cast spells on Lin Yun's side. The overwhelming spells were like four-colored rain, and sprinkled down this side.

The alchemy urn like the long-legged magic crystal cannon on the wall continued to cast. The alchemy puppets in the cave openings exposed on the wall surface also followed the cast.

The dazzling flame of light burst out. Huge fireballs with a diameter of more than ten meters burst from the inside and flew towards Lin Yun's side.

The gray orcs combined their advantages to fight back unexpectedly powerful.

And here, the cast alchemist and the mage army cast spells together, and the torrent of spells rushed over the walls of several Gray Orc fortresses, the patterns on the bright metal plane on the surface of the wall. Suddenly a large block lights up.

A faint light film covered the wall surface, and a large number of spells fell on it. The range of lightening patterns on the surface of the city wall has only been enlarged, and the wall cannot be damaged at all.

On the contrary, the Gray Orcs were able to cast unscrupulous attacks, and a large number of spells fell. After half a minute, Lin Yun took the person back and started to retreat. When the Gray Orcs' offense began to slow down, it began to slow down. .

This distance is very difficult to have such a large range of attack unless the magician of the titled magician level casts. Those alchemists are only those who are five or six meters tall, like magic crystal cannons with long legs. Alchemist can have such a large range of attack.

However, the frequency of these alchemy cricket attacks is too low. After releasing a huge fireball with a diameter of more than ten meters, it will take at least a minute to stop casting again. Each time the cast, the time to gather strength is too long. Already.

After the attack direction was determined, it could not be changed at all. There were too many defects, which could not be compared with the magic crystal cannon. Although the power was huge, except for facing the situation of defending the city, there was basically little effect. Gray Orc It seems that the defects of these alchemy urns are also known, so they don't make many, only a dozen.

The huge fireballs with a diameter of more than ten meters are comparable to the strongest seventh-level spells. When facing a large group of enemies, they cover a range of more than ten meters. After being exploded, they can cover a range of tens of meters. Deterrence is the greatest.

Lin Yun led people back and did not continue to attack, just surrounding the Grey Orc fortress.

Before coming, Lin Yun knew that the Gray Orc's fortress must be a very difficult hard bone, and did not expect that the Gray Orc was so afraid of death.

The wall was over thirty meters high, and the surface of the wall was covered with a whole layer of magic resistance metal.

Those metals are all magic metals with excellent texture. They can be sold in the alchemy store in the human kingdom, and they can be used as city wall bricks in the gray orcs.

And if you want to achieve this effect, the thickness of the alloy metal plate is definitely thicker than the thickness of the plate armor. Coupled with the alchemy process, you can describe the leveling matrix, lay down the alchemy lines and runes, and even let each metal The board can be integrated with the metal plate next to it, at least all the formal alchemists can barely try it.

Looking at the wall, it is several kilometers long on one side, and the number of metal plates needed is a very large number. Even if the Grey Orcs almost know all about alchemy, the number of alchemists is even more heinous. In order to complete these magic resistance metal plates on the surface of the city wall, it will take several decades for the entire race to start together with sufficient materials.

The time it takes may be hundreds of years of accumulation to complete this scene ...

Lin Yun couldn't help but sighed, it was a luxury ...

The resources spent by these gray orcs to build this wall almost made a large family bankrupt directly. All the forces in the entire Kingdom of Andalusia were clamped together. It is estimated that they could barely make up the resources needed for this fortress wall.

And those alchemy circles are obviously a very rare non-level alchemy circle. A metal plate is the most common alchemy circle, but when a sufficient number of them are stacked together, the level of the alchemy circle will increase. The stronger.

Theoretically, as long as it is large enough, the rank of the magic circle will be infinitely increased, and the power will be infinitely increased. For hundreds of years for these Grey Orcs, they will continue to expand the city wall that protects them and the number of metal plates More and more, finally converging together to form a heavenly alchemy, it is not impossible.

At that time, even if the Heavenly Order's strong man comes in and shoots himself, I am afraid that they will not break the walls of these gray orcs!

The stronger the attack, the larger the range of alchemy activated on those metal plates on the surface of the city wall. As long as the reaction limit or load limit of these metal plates is not exceeded, it is impossible to destroy a brick on the city wall.

This desperate method is rare even when Northrend's world has reached its peak. How terrified is death and how insecure it is ...

I knew that the gray orcs had a weak body, so they valued their protection. This is why the alchemy technique has been imprinted into their lives and bloodlines, but they didn't expect these guys to make such a turtle shell.

Lin Yun took people back and did not make unnecessary sacrifice. The magic energy array has captured the lines of the alchemy circle on the city wall, and then constantly combines those alchemy lines and runes to see how this alchemy circle can be cracked. .

Lin Yun stopped attacking, and the Gray Orcs didn't dare to attack, so they froze.

After two days, this situation was still maintained. As long as Lin Yun's men were a little closer, the gray orcs who were patrolling at all times on the city wall would be attacking like crazy immediately.

Unless you can break through the door of the Gray Orc fortress, such a strong attack will not have much effect. It will only increase the casualties. It is even more important to fly from mid-air. There is a huge air defense tower every few hundred meters on the city wall. A few hundred meters apart can clearly sense that the air defense tower is operating at all times ~ lightnovelpub.net ~ As long as anything is close to the defense range above the fortress, it will be hit with terror like a live target.

The main defense object of air defense towers is the sky. In order to strengthen this, basically all air defense towers are unable to attack people who are close to the decent or on the ground.

Flying over is not enough. Basically don't want to break through the wall on the ground, you can only find a way to attack from the gate.

On the third day, the Gray Orcs were holding on to their plans to stay dead, and they didn't come out at all. Lin Yun began to turn around the Gray Orcs' fortress.

Such a large city, and the entire race of the gray orcs are in contact with the alchemy of alchemy, so they need a lot of water resources. In addition to normal drinking and washing, the demand for water in other places is several times more than this.

The whole fortress was blocked. What water do they use?

The fortress is adjacent to the junction of two rivers. If it is normal, they do not need to worry about water. Now the fortress is closed. They are not nervous at all, and they can see that there are many chimneys in the fortress. The black smoke indicates that they are all working hard to build the alchemy urn. (To be continued)
