Reykjavík's defense system is not like Notting Khan, which took nearly four years to build without even a frame, but like a balloon blown up, relying on the system and "low-quality" material permafrost and rock in a short period of time, it looks very grandiose but is actually a brittle shell.

Despite this, Sun Lin cannot deny that the ability of the skilled craftsmen who never set the sun has indeed reached the level of masters, and in only one month of construction time, the walls of Reykjavík are not only installed with external baffles that can absorb arrows, stone troughs that throw 100 catties of stones under the walls, but even the simple combination of iron chains and steel wheel hemp ropes to form an item lifting platform fixed behind the city wall.

After Sun Lin ordered the use of fire oil, some idle engineers immediately ran down the city wall to extract the open space in the rear, which had been burned into a black oil pot by the fire, and then went up to the wall again, and used a simple crane to pull up the huge iron pot that had been shocked in the city defense battle of the northwest continent before the sun never set and installed it on the tilting device.

"Ready............ Get ready......... Pour! "Seeing the time of the sun, the engineers began to pour from the middle to the outside as the two reindeer cavalry moving back and forth were about to alternate at the gates of Reykjavík. The hot, pitch-black oil flowed like flowing magma down the frozen rock wall with an inclination of about 80 degrees that had been specially designed for the oil during the previous construction, and flowed to the feet of the reindeer cavalry in the blink of an eye.

In the process of this period, the sound of the boiling hot oil eroding the frozen soil and rock and melting it, that is, the engineers who personally hoisted the big iron pot with a pole felt a cold and toothache, and the ground through which the oil passed, not only the snow on the surface was melted, but even the frozen soil turned black.

The reason why Sun Lin used the method of pouring fire oil to solve these reindeer cavalry was not to burn those reindeer cavalry with fire oil, but to make those reindeer groups go crazy.

Animals will always have a stronger sense of crisis than humans, and they are more sensitive, so when the fire oil rushed towards the reindeer cavalry, these armored reindeer began to flee out of the control of the reindeer cavalry out of the instinct of escape. And this change immediately caused the formation of the reindeer cavalry to begin to be confused, and you must know that the reindeer under the crotch of the reindeer cavalry moving on the outside line at this time did not feel the appearance of fire oil, and still kept the formation moving forward. As a result, the reindeer near the city wall suddenly moved outward, not only breaking up the formation of the reindeer cavalry on the outer cloth, but also because of the irritated control of the reindeer cavalry, the two reindeer cavalry were all entangled in front of the city wall, and at this time, the fire oil had begun to contact the four hooves of the reindeer closest to the city wall.

Anyone who has known horses knows that when you use tongs to burn the horse's buttocks, the horse will generally make two reactions, one is to kick the legs backwards, and the other is to run forward in a frenzy, and the reindeer and the horse are more similar animals, they both belong to the mammalian hoof, although one is a cloven hoof and one is a strange hoof, but the reaction to this kind of thing is the same, and from the current situation, it is obviously impossible to kick the legs backwards, then these reindeer can only choose the second way - crazy forward galloping.

At first, nearly a hundred reindeer suddenly went berserk and wounded the other reindeer cavalry with a horn as strong as steel on the top of their heads, but as time went on, more and more reindeer began to go berserk, and more and more reindeer cavalry were knocked to the ground, waiting for the hot oil to flow into their armor. At the end of the day, the surprise attack of the oil caused the reindeer to go berserk in a total frenzy, and among these reindeer that were not controlled by the reindeer cavalry, the lucky ones rushed towards the two wings of the battlefield, while the unlucky ones rushed towards the snow armor soldiers and snow heavy armor soldiers.

At the same time, Sun Lin, who saw that the effect of the fire oil on the city wall had reached his expectations, and even surpassed it, hurriedly shouted: "Quick! Hit all the canister throwers! Hit the tails of those mad reindeer! Drive them to the side of the Snow Armor! ”

On the other hand, the snow armor soldiers and snow hoplites, who had begun to continue moving towards the walls of Reykjavík, had not been happy to take a few more breaths of turbid heat before they could be knocked away by the reindeer in heavy steel armor that appeared in front of them. The soldiers on the city wall and the alliance commanders who watched from afar could clearly see that those reindeer were like a torrent of steel that knocked the scattered coalition soldiers into the air one by one, although in the end the formation of the alliance army was not pierced or crushed, but it was visually seen that at least nearly 10,000 coalition soldiers died in this bloody trampling in the past, especially those snow armor soldiers who only had silver and white steel armor on their bodies, and now there are very few people who can see it as far as the eye can see, and those reindeer cavalry who have also suffered so badly, There are not many reindeer that can be found standing and running after a bloody trampling, and it is a miracle that only one surviving reindeer cavalry can be found on the backs of these reindeer.

Of course, the attrition of these personnel is not the point, the point is that the iron siege ladders that the snow armor soldiers and snow heavy armor soldiers had before have all been damaged, and the same is true of those steel bone siege vehicles, that is to say, now those silver moon archers may still be able to shoot arrows at the city wall, but these allied hand-to-hand soldiers can only stare at the city wall.

However, Sun Lin was not happy about this situation for too long, because ..........

"Boom! Rumble! ”

"What are the engineers of the giant crossbow defending the city for? The boulder machine doesn't fight back! Sun Lin shouted at an engineer beside him. And he was leaning against the wall, finding peace from the previous vibration.

"Hug, sorry, Your Majesty! The operators of the giant crossbow guarding the city had found out that the other party had sent the remaining dwarven centurions, and all of them turned to the dwarven centurions to destroy the machines, but we didn't expect the enemy to use those siege weapons to pull the megaliths, and the result was .........," said one of the engineers with a look of shame

"As a result, you didn't notice that those dwarf centurions had two ropes tied to their hands, and you didn't find that the other end of those ropes was on top of those boulder machines, okay, I know, what's going on now?" Sun Lin asked with a solemn face.

"It's okay, 6 giant crossbows defending the city were smashed, but those giant stone machines that were pulled up by the dwarf centurion have been wiped out........." Before the engineer could say anything, a herald suddenly ran outside the arrow tower of the city gate tower, and rushed in and shouted: "Your Majesty Sun Linmian, you go out of the city and have a look!" The enemy launched a general attack, and all those siege vehicle towers were pushed up by the Mo Forging people! ”
