The clone of Kailigan, who was standing on the city of Ulla, saw the Lockland army in white armor retreating like a tide but did not relax, she knew that the Lockland people were only temporarily retreating, and a phalanx of 10,000 people in the distance was actively waiting.

Looking back at the corpse of a bug on the city wall being dragged into the city, where are there several bases hidden underground that are responsible for converting energy and producing new Zerg bases, but unfortunately the number of bases is too small, and the replenished Zerg can only be described as a drop in the bucket.

He still had 400,000 swarms in his hands when he attacked a few days ago, but as Rockland's army rushed into the city again and again, the swarm in his hands had been reduced to less than 200,000. What worries her even more is that the city gate has been shattered by several sword heroes, and if there are a few more such attacks, I am afraid that the city gate will be lost.

"Woo~" A high-pitched horn sounded, and the 10,000-strong phalanx that had been prepared began to slowly approach Ula City.

Kairigan squinted her eyes and counted, each phalanx was nearly 10,000 people, this was a whole legion launching a general attack on herself.

The city of Ula is located in the remnants of the Gulgas Mountains, a hundred years ago, the vast land north of Ula City belonged to the territory of Jace, but because of the insatiable Locklands, they had to withdraw from this land, and built the city of Ulla, known as the first barrier of the commercial kingdom, which directly turned away the greedy Locklan Kingdom, so that the Locklan people can no longer find any excuse to invade the territory of the Jaces. The existence of Ula City makes it impossible for Locklan to take advantage of it unless he invades the permanently neutral nation on a large scale.

The walls to the north of Ula are twenty meters high, and are magically fortified to make it virtually impossible for the Locklands to be destroyed by unarmed Loclelands. The north wall is 3,000 meters long, and if you attack the city with a dense battle formation, it is already the limit to put 20,000 people at a time, and it is precisely for this reason that the Zerg can still hold the city, but now the city's walls are basically about to be filled, and a hill made of earth and stone is the biggest enemy of Ula City.

Kai Ligan had to admire the imagination of human beings when attacking the city, what crashes, ladders, digging tunnels, poisonous smoke and even filling the city wall with earth and stones were used, but the above methods were all cracked by Kai Ligan one by one, but at present, this hill that is basically the same as the city wall makes Kai Ligan very helpless.

It took two days for the Locklan army to pile up a hill flush with the walls 200 meters outside the walls, which was arguably not difficult in such an era of magic, although Kelrigan harassed several times with bone snakes and bone eaters without success. However, here Kelligan is also very glad that the Rocklanders are not crazy enough to use the level 9 Grand Magister to use the forbidden spell to flatten Ulla City, and it seems that they are also extremely taboo about the high-end combat power of the Zerg. And Lockland's hybrid magic is obviously not as powerful as Saint Ulan's, and they won't break the forbidden spell with a large hybrid system at all, after all, they are the Ice Kingdom and not the Magic Kingdom......

After piling up a 20-meter hill outside the city wall, the Locklan army began to fill in the earth all the way to the city wall, gradually making the hill an earthen wall slowly approaching the city of Ulla, and when this earthen wall was only 100 meters away from the city of Ulla, their fangs were exposed, and they set up a 100-meter siege ladder strengthened by magic between the earthen wall and the city of Ulla, and most of the subsequent time was spread out between the bridge erected by this ladder.

Although Kelrigan ordered some of the remaining magic crystals to bombard a few ladders, the loss of such cheap things was not a problem with Lockland, and they also launched a feint attack under the city, and if they focused too much energy on the ladders, the city gates would be dangerous.

In fact, Kelrigan is not averse to the Zerg and humans in close combat, and the small environment limits the numerical advantage of the Rockland army, which makes the puppy who is very good at melee and the sneak attack expert Stinging Snake perform extremely well in this offensive and defensive battle. And once the Rockland army uses six or seven level high-level warriors or knights to raid, the more than 100 wyverns and soldier ants that Kelligan has hidden in the snow will have something to do, in fact, there are still 20 mammoths waiting for them behind the castles, and once the city gates are breached, they will become new city gates......

"It's become a war of attrition again, you go and tell Hirafu that if his division can't do it, he should withdraw quickly, there are many divisions and regiments that want to make meritorious contributions, and he is not the only one." Tunguska, the commander of the Northern Demon Legion, yelled at the heralds, because the lack of strength in the Azur attack had already caused Brishi's displeasure, and he didn't want to be the next marshal to be reprimanded.

"Boom!" The city gate was split in half by a knight with the title, and the city gate had already been smashed by the fighting spirit in the attack of the past few days, and now the attack of the knight with the title finally became the last straw that crushed the camel.

"Damn, can't you hold on?" Kelrigan quickly ordered a mammoth to rush to the city gates.

The Locleland soldiers, who were rejoicing, suddenly felt that it was dark in front of them, and a huge body blocked the eight-meter-high city gate...... The mammoth's 20-tall body is basically the same as the city wall, so it is natural to block a small city gate.

The Title Knight filled his sword with Fighting Qi, and then a dazzling blade of Fighting Qi slashed into the thick carapace of the mammoth.

"Boom!" The mammoth staggered, and although the blow did not cause it any substantial damage, it did cause the mammoth to take a few steps back and let go of the blocked gate.

"Kill!" The army of Locklan rushed into the city of Ullah.

"Roar!" The mammoth was furious, raised its front hooves and stomped on it, splashing pieces of flesh and blood everywhere on the city walls, and the bloody scene made the Locklan people breathe.

"Look for death!" The knight of the title rushed forward with an arrow step, and with a kick of his feet, he leaped over the mammoth, pouring his fighting energy into the long sword, and after a burst of dazzling light, the long sword pierced the carapace of the mammoth and sank into the mammoth's body.

This knight is obviously not a good kind, and it is extremely difficult for ordinary eighth-level professionals to hurt mammoths, but there will always be some geniuses who are different from ordinary people, just like this knight with the title of the soul of light.

The mammoth roared in pain, and the long sword stabbed at his body, and its proportions were like a normal person being pricked with a toothpick, but the fighting energy of the soul of light directly entered the body of the mammoth with the help of the transmission of the long sword, raging like a blade, in the face of such a special light fighting qi, the mammoth had no way except to sway from side to side like crazy, and its size brought it a huge advantage but also a huge disadvantage.
