Slowly leading the troops to climb the hillside of the volcano, the scenery in front of Yang Yu turned from lush forests to sparse bushes.

Immediately afterwards, the shrubs disappeared, and only some low vegetation could be seen. In the end, Yang Yu only had various colors of gravel in his sight, which completely turned into a deserted area.

Given the special nature of Chihuo City, the fortifications built by Chihuo Clan are also very different from ordinary cities.

Apart from regular grazing and going out for a few things, the Fire Clan rarely leaves the city where they live.

They would stack stones at the entrance of the cave, making the entrance of the cave integrated with this deserted area covered with gravel.

If it was the first time someone came here, there would be no way to know where the entrance to the Chihuo Clan city was hidden in these gravel piles.

The Fire Clan will use volcanic rocks that fit their abilities, like cave-dwelling spiders, to lay invisible magic networks around the entrance of the cave.

As long as a large creature step into the magic network, the Fire Clan guarding the entrance of the cave will immediately sense it.

If those large creatures are judged as enemies, the warriors of the Fire Clan will use their abilities to induce the stones blocking the hole to explode, causing the hot stones to splash out and burn the surrounding enemies.

At the same time, they will ignite the magic power arranged on the ground, and then create a large sea of ​​fire on the hillside, making it difficult for the enemy to escape.

Celebrating that the volcano will become bare halfway up the mountainside, there are some reasons for this.

If the enemy is very fierce, crosses the vast sea of ​​fire and leads to the city of Fire, it is also very suitable for the use of flame magic.

The rules set by the dragon protect those who are clearly involved in this battlefield.

The Fire Clan did not intend to participate in the war at the beginning. It was a relatively independent race and had no organization.

Therefore, they do not have to be bound by the rules of the dragon, and can use large flame magic to defend and counterattack and resist aggression.

Even so, the Luoze Empire captured their city.

The Chihuo clan, who was forced to fight with the world, could only seek organization.

How did humans know the exact location of each hole and how they used to break through the defense of the Fire Clan? People from the Fire Clan did not know.

Many of the Fire Warriors guarding the entrance of the cave were captured by the Luoze Empire and their whereabouts were unknown.

There is a very likely hidden secret weapons that the orcs don’t know about in the Luoze Empire.

Yang Yu and Jerky Mu quickly formulated a combat plan, first dispatching troops to conduct a tentative attack on the hole identified by the Chihuo clan, and then make countermeasures based on the situation.

Soon, the first tentative attacking force was assembled.

Since the feet are covered with sharp stones, this tentative attacking force is mainly composed of agile hunter-shaped orcs.

They used their agility to approach the entrance of the cave in one breath.

Suddenly, Bai Jin felt a large amount of magic power gathering at the entrance of the cave.

Magic arrays formed without warning in front of several piles of gravels, and countless flame magic shot towards the vanguard of Wansheng Kingdom.

Bai Jin and other orc magicians hurriedly sang magic and protected the orc troops together.

In an instant, several different powerful magics collided together on the hillside, and majestic energy poured out, inducing strong explosions on the mountainside.

Accompanied by roars, countless stones were lifted up by powerful magic and turned into powerful black bullets, slamming into the bodies of the orc vanguard troops.

Blood scattered on the dark stones, and several beast soldiers fell.

The orc magicians quickly transformed magic and no longer launched magic hedges, but used defensive magic to cover the vanguard's troops to withdraw.

The vanguard suffered such a swift and precise blow that Frozen Mu frowned.

Humans clearly do not have the excellent hearing and smell as orcs as orcs, but they sensed their approach through the pile of rocks and launched such an attack on them.

How did they notice that we were approaching?

Could it be that among the gravel, humans have arranged small surveillance magic to monitor the situation on the hillside at all times so that they can attack as soon as possible?

Or can they also be like the Fire Clan, able to spread the magic gods around the cave entrance without realizing it, and through the vibration of magic, they can learn the direction of the orc troops' movement?

Frozen wood dared not make a conclusion lightly.

After the vanguard troops completely retreated, Jerky Mu immediately ordered the magicians and archers to attack the entrance of the cave. However, their attack was completely intercepted by a light blue light shield spreading from the entrance of the cave.

It's a barrier.

The Luoze Empire installed barriers on each cave entrance after occupying the Celebration Volcano.

Looking at the unbreakable light blue barrier and blocking the orcs' attacks again and again, Yang Yu knew that this would be another tough battle.

When congratulating the cities around the volcano, Yang Yu found that some cities had surprisingly little supplies and did not support long-term combat at all.

However, under Yang Yu's guerrilla tactics and the strategy of surrounding the cities in the countryside, there was no obvious lack of material resources.

After careful investigation, Yang Yu basically found a small teleportation device in each city.

Those teleportation devices are only the size of a box, and it is difficult to use to transport people, but it is easy to use the magic scrolls used to transfer stored items.

There are several specialists in charge of the transmission device. When they see that the situation is not good, they will take the initiative to shut down the transmission device.

The city that stores materials will not distribute materials to the magic device after receiving this message.

Once, Yang Yu tried to sneak in, and when the soldiers were not paying attention, he took away the teleportation device and intended to get the other party's supplies for free.

However, Yang Yu did not expect that if you want to exchange materials, you must use the crystal ball to match the password that the Roze Empire regularly switches.

From Bai Jin, Yang Yu learned that the magicians used in this small transmission device mainly use one-way transport, and several equal small transmission devices cannot be interconnected.

If you want to deliver supplies to the army regularly, you need a more complete and powerful teleportation device.

There is no need to say much about where this device is.

Even if the teleportation device established in Chihuo City cannot fully cover the surrounding area of ​​the Celebration Volcano, it is enough to cover most of the time.

In addition, Yang Yu also learned from Bai Jin that if the large-scale transmission device is completed, it can not only transmit objects, but also people can transmit them.

By simply using teleportation magic near the teleportation device, or building another teleportation device directly within range, the Roze Empire can simply place soldiers around the Celebration Volcano.

As long as the Chihuo City of the Chihuo clan is not captured, the Luoze Empire will still have the opportunity to celebrate the Volcano's big-name writing.

Such an important location is naturally guarded by heavy troops.

This city has no walls, but this siege is perhaps the most difficult thing in history.

The fire city is under the pile of rocks, and no one can tell what strange things are waiting for them under the pile of rocks.
