There was no doubt that this was the focus of everyone on the battlefield, and perhaps this was the turning point of this war, but the moment the hammer landed on the city wall with all its might, there was another loud bang.

This time, however, the sound was different, this time it was more muffled, like a mallet on a drum, and the walls were not as destroyed as expected.

After withstanding such a huge impact, no matter how you think about it, it should have collapsed, and it is obvious that what the human side has done.

It is not difficult to see why the walls were not destroyed, and now the entire wall has changed, and from a distance, the walls have turned completely green, shining in the sun.

If you look closely, it is not difficult to see that the surface of the city wall is covered with a layer of green things, this thing is crystal clear but extremely strong, obviously a kind of ore, people who really know the goods will immediately recognize it, this layer is jade rough!

Like Mithril, this is also a special ore, and Mithril is the opposite, Emerald Stone is used to resist physical damage, and the hardness of Emerald itself is actually very average, and it can be cut by a sword, but the peculiarity of this ore is that it can be cut by sharp objects but is difficult to be destroyed by brute force.

It's like cutting through cotton easily with a sword, but it's definitely hard if you want to break it up with brute force.

It is precisely because of this layer of jadeite covering the outermost part of the wall that the city wall actually blocked the blow of the battering ram, of course, the jade that came into direct contact was still shattered, revealing the cracked wall inside, which is definitely not so strong here.

The question is, where did this jade come from?

Obviously, as long as you are not a fool, you will be suspicious of the last of the three major fortress cities of the "Day Do Not Fortress" - the Emerald City.

The city is completely made of jadeite, the smallest and strangest city, the most ordinary people do not see clearly, but in the high place of Andula can see very clearly, in the underground of the Emerald City carved a special magic array.

It is impossible for Jade to directly turn the entire city into a huge magic weapon like Mithril, but it is still possible to carve a huge magic array under the city, and this magic array is still a very special "refining magic array".

This kind of magic array has neither attack nor defense power, and its only role is to refine materials, and many priests, pharmacists, and other professions are proficient in this kind of magic, and they are often used when refining weapons.

Now that the entire Emerald City has also changed, the Demon King Army, who was originally crowded in front of the city wall, was surprised to find that there was some distance between themselves and the city wall.

Of course, it wasn't that they retreated, but that the Emerald City shrunk.

The whole city has shrunk and become a whole circle smaller, but due to the peculiarities of the city's structure, the city's defense function has not been affected much, and it is clear that this situation was taken into account when it was built.

Just a moment before the hammer landed on the city walls, the city finally played its special role.

The alchemy magic array under the foundation of the city was activated, and such a huge alchemy magic array had never appeared before.

And the material sacrificed by refining is naturally this "Emerald City", and the object of refining is the entire "Sun Don't Fortress" city wall!

In principle, it is really simple, that is, the entire city of jade is re-refined, and it is refined to cover the city wall to form a layer of defensive wall, and I don't know who came up with such a crazy idea to carry out such a large-scale refining on the battlefield.

But judging from the results, the effect is simply great, the original city wall is strong enough, the linkage magic array can resist long-range attacks and a lot of magic damage from a distance, and now this layer of jade can withstand the physical damage after close combat, it is simply invulnerable.

And it was only refined at the most critical time, which really caught the Demon King Army off guard, so it was really difficult to destroy the city wall.

Everything happened in the lightning and fire, but the Demon King Army still did not give up, after a short period of shock, the Demon King Army pulled the battering ram again, even if this jade wall can block an impact, it is impossible to block the next time, there must be a time interval for the huge refining magic array like the Jade City to be cast.

But contrary to their wishes, the soldiers who were attacking Silverlight City found that the city had moved again, and a force quickly erupted from it.

If you look at it from a high altitude, it is exactly the same as the shot that killed the red dragon last time, the silver light began to flash from the outermost part of the silver light city, and quickly concentrated on the crystal in the center of the city, but the difference is that the silver light this time is much weaker than before, even after the final concentration, it is far from being compared with the last time.

This cannon should have been forcibly launched without completely gathering energy, after all, the "Silver Light City" has not yet completed a complete cooldown, and it can only be used to reduce the power in this way.

The silver light traveled through most of the battlefield and landed on the siege vehicle with unmistakable accuracy.

The speed of the silver light was amazingly fast, and even Andura, who saw all this, had no time to stop it.

There was no explosion, and where the silver light landed, everything was evaporated, and even the battering ram that the magic crystal cannon could not destroy was completely melted into a pile of scrap metal in this silver light, and the demons within the range of the attack were all turned into ashes and dissipated.

Even the power of the reduced version has such terrifying power, this "Silver Light City" can really be called the ultimate weapon of mankind.

At the moment of releasing the light, the linkage magic array did stop running again, but this time there was almost no loss, after all, the city wall is still wrapped in a layer of jade, which can ensure the defense of the city wall in a short time, and this kind of cooperation is very suitable.

With the destruction of the siege engine, a burst of cheers suddenly resounded on the human walls, and a great crisis had been resolved.

And at this time, the Demon King Army finally showed fatigue and began to struggle, which was not caused by low morale, but because of the lack of stamina.

Restricted by the teleportation ability of the "Demon Gate", the number of demon king troops who can set foot on this land is still limited, and this is not the demon world after all, fighting here can be regarded as an away battle, and the longer it drags on, the more disadvantageous it will be for the demon king army.

This war has been carried out so far that it can no longer be described as corpses all over the field, although many human soldiers have been killed, but the dead demon army is simply a terrifying number that cannot be counted.

If you don't change your strategy, I'm afraid this will be the turning point of the defeat of the Demon King Army......
