The most powerful thing about the Winter Fortress is that it can continuously draw lava from the earth's core as a replenishment.
As long as the face of the earth's core is not cut off, the protective shield of the entire Winter Fortress can continue to operate.
Of course, this protective shield has a threshold. As long as it does not exceed this index, it can maintain a continuous defense.
It is not easy for a Jindan powerhouse to break through, which is why the Winter Fortress is so confident.
In order to build this city defense formation, Li Tianyu used a lot of his resources.
This city defense formation was not created by one person, but by multiple formation masters at the Jindan level. Master Li was one of the people who created it.
Master Li is a very powerful formation master among the Jindan powerhouses. Many princesses' kingdoms in the entire Shenzhen Linhai and even the seven major countries have hired him to create city defense formations.
However, Master Li's personality is also very strange. Some of the formations he made are very good, while some of them are very strange.
The Winter Fortress was a formation he had created when he was just playing around.
This formation is extremely similar to the one in Beihua City, but the biggest difference is that the protective shield of the Winter Fortress is weaker than that of Beihua City, but its replenishment ability is stronger.
As long as the opponent's attack speed decreases, the replenishment force will increase rapidly, and then the protective shield can be quickly replenished.
The defensive capabilities of the Winter Fortress are obviously stronger than those of the North China City, and its weaknesses are not obvious.
Feng Jiutian knew this, so he knew that if he wanted to take over the Winter Fortress, he would have to pay a price. There was no other way but to use a brute force attack.
The defense of Winter Fortress was indeed very fierce, but it showed its strength from the very beginning.
Almost at the first moment when the demon army launched an attack on the protective shield, countless ribbons appeared around the city defense formation. These ribbons fell towards the Yao army like meteorites falling from the sky.
The center of the demon clan’s huge army suddenly exploded, with flames and smoke everywhere.
The entire battlefield suddenly became chaotic, and all that could be seen was the soldiers on the city wall continuously shooting arrows towards the people below.
The demon army below was launching continuous fierce attacks on the human city as if they were not afraid of death. Many large demons in front of them were killed or injured.
However, this could not stop the monsters' attack at all, perhaps because the lower-level monsters were not very intelligent.
This caused great trouble to the human city wall. Even if the demon army in the front suffered heavy losses, the demons in the back would soon rush up, stepping on the piles of corpses in front.
"How come these monsters are so brainless and so fearless of death?"
Li Tianyu frowned slightly as he looked at the battle situation in front of him, feeling a little uneasy.
Just from the current situation, it can be seen that the opponent must have very strong combat capabilities.
The ferocity of the army was also very strong, which was enough to show that the attack they suffered this time was very terrifying.
The demon army is indeed an elite force specially trained by the Demon Alliance, and they are indeed fearless of death.
Then at this moment, Li Tianyu suddenly saw a very huge spiritual power fluctuation coming faintly from behind the demon alliance not far away.
The range of this spiritual power fluctuation is very wide, covering the entire offensive battlefield of the demon army, but at the same time this fluctuation is not particularly obvious and is difficult to detect.
If I hadn't been observing it all the time, it would have been difficult to notice this situation.
When Li Tianyu thought of this, he quickly turned his gaze to Mu Tianhai next to him.
"You should have felt it too, right? There seems to be a magic circle forming behind the demon tribe, and this magic circle seems to be covering the entire battlefield."
Mu Tianhai's strength is even stronger than his. Li Tianyu naturally knows that the other party must have noticed this situation a long time ago.
As expected, after hearing Li Tianyu's words, Mu Tian just nodded lightly, and then explained.
"I had already noticed this situation a long time ago and was able to determine what they were doing."
"If I'm not mistaken, the reason these monsters are so fearless and charge so fiercely is because this magic formation can enhance their physique and speed, allowing them to enter a state of hyperactivity."
"The demons are also made of flesh and blood. It's absolutely impossible for them to have such strong willpower. So if we want to destroy their morale, we must first find a way to get rid of this magic circle. But so far, I have no idea."
The opponent's magic circle can cover the entire battlefield, helping the demon clan improve their combat effectiveness and morale.
If it were a normal battle, they would definitely solve this problem first, but it is obvious that it is unrealistic for them to solve this problem now.
The demon army is just ahead. If you want to attack the opponent's magic circle, you must have a force that is strong enough to break into the opponent's position.
But it is obvious that they do not have such powerful strength now.
Being able to use all your strength to defend against the opponent's attack is already using all your skills. As for the rest, there is no need to think about it at all, there is no possibility.
Li Tianyu shook his head helplessly, knowing in his heart that even if they knew the opponent's weaknesses, they would have no chance to attack.
The Demon Alliance will definitely deploy a large number of troops around the political and legal system, and it will cost a huge price to break through there.
Rushing forward rashly will only bring more losses to our side, so it is better to defend the city.
However, this information was very important, and Li Tianyu remembered it in his heart.
The demon tribe is still attacking the entire city. The defense of the Iron Legion's city walls is indeed very powerful and is constantly consuming the demon tribe's strength.
The protective shield was constantly breaking and repairing itself.
Thanks to its powerful recovery ability, the facial protection shield is still glowing red until now.
The demon tribe has already launched a second round of attack.
The attacks of the demon tribe have always been extremely fierce, and every attack they launch will cause huge casualties to the entire Winter Fortress.
Some of the demons in the distance were able to spray energy shells at extremely long distances, continuously launching fierce attacks on the city walls.
The protective cover also suffered a lot of damage as a result.
