After Her Majesty's order was delivered, the craftsmen once again introduced trebuchets that had been restored again with great difficulty. The soldiers took over the trebuchets and, when they were ready, aimed at the city walls and began to bombard them violently.

Ignited boulders streaked across the sky like meteors, illuminating a large area of the sky between the Imperial camp and the city walls, and the boulders followed the parabolic trajectory and slammed into the walls with heavy force.

The tribal defenders who were holding a bonfire were singing ancient songs passed down from the tribe around the bonfire, and the gathering reached its climax.

Unexpectedly, a flaming boulder landed on the campfire where they were dancing around, and in an instant flames flew everywhere. Some of the warriors who were standing far away were immediately shocked by the shock wave outside the walls, and the sound of their fall from the walls to the ground was so loud that the people of the entire section of the wall could hear it clearly.

The rest of the people were not unscathed, their hair and bodies were generally burned by the splashing flames. These days the weather is very dry, and the slightest spark on a person's body can quickly spread into a fire.

The slightest spark on their bodies quickly turned into a fire, and they cried out in pain as they rolled on the ground, trying to extinguish the fire on their bodies. There were also lucky soldiers who carried buckets of water and poured water on their comrades, but all efforts were in vain.

In the early years, in order to study the method of killing the enemy on a large scale in war, the Imperial Academy developed a special fire oil that is flammable and difficult to extinguish, which has never had the opportunity to come in handy, and now the Academy can finally test its effectiveness in this war.

The academy professors who accompanied the army were excitedly recording the tragic situation of the tribal barbarians, these were precious experimental data, and in the eyes of many people in the academy, human life was far less important than experimental data.

The fire quickly spread to most of the city walls, and the banquet held by the Snowfield Tribe to celebrate the victory coincidentally provided a good opportunity to make the special fire oil more powerful, and the bonfires stacked in patches were simply the best trigger, and the fierce flames burned more and more vigorously on these bonfires.

Gladys quickly noticed movement on the city walls, and the materials for these special oil preparations were expensive, and they were not much for the sake of the nature of the experiment. She had just had the idea of experimenting with the soldiers pouring the oil on the surface of the boulder, but she didn't expect to have an accident.

Seeing that the city wall was already on fire. The defenders of the city are now too busy to extinguish the fire, and now is a good opportunity to siege the city!

The Empress ordered the scouts to keep an eye on the city walls, and the defenders of the city must have been exhausted from the long fight against the fire. When the fire is extinguished, it is the time when the enemy's defense is the emptiest, and then it is the best chance for the city to be breached!

But before Gladys's order could be heard, a rain cloud gathered in the sky near the city walls. It's unbelievable that this rain cloud can cover a terrible small area, and it can't even take into account the location of the Imperial camp.

The climatologists in the academy stared at the rain clouds gathering in the sky with wide eyes, and muttered, "This is simply impossible! How could such a small rain cloud suddenly appear without warning?"

And yet such a spectacle happened in front of everyone's eyes. The rain clouds soon gathered together, and there was a faint thunder in the clouds, and after a lightning and thunder, a torrential rain fell from the sky, and the raindrops as big as beans fell on the fierce city walls, and even the stubborn fire oil could not withstand such rain, and soon the fire burning on the city walls was extinguished by the torrential rain.

The rainstorm was not over, and gradually some tiny pieces of broken ice fell from the rain clouds, which soon melted together when they fell to the ground, and the walls of the city wall were soon covered with ice. After the flames were completely extinguished by the torrential rain, the rain clouds gradually drifted away from the sky.

Gladys stood froze, like many others who didn't understand what was happening. Why is it that at this time, it rains heavily in the sky above these walls? Is it just a coincidence?

No one could answer her question, because this was not the phenomenon that should exist in this world in the first place.

At this time, in the square of the city, Gale was still immersed in the shock of the moment, and in front of him a group of minotaur priests and gnolman priests were slowly leaving a huge magic circle.

They had just worked together to cast their magic, and he watched as the strangely shaped priests summoned a rain cloud, which he controlled to extinguish the flames on the city walls and save the city in distress.

Poppy walked up to him with a hint of smugness and asked deliberately, "Your Highness Gail, the magic of our priest of the abyss is very powerful, haven't you seen it?"

Gail slowly recovered from the shock, he nodded and replied, "Indeed, the magic of your priests is very strange, I can't understand this magical power at all, if your priests can control more powerful forces, then it will be easy to defeat the imperial army!"
