The wizard's eye has been monitoring the movement of the whole grey dwarf city at high altitude. With the help of group invisibility, the army of Zhenbei city slowly and firmly moves towards the grey dwarf city.

The land outside the city is flat. Some edible fungi are planted in many places, which is the main food source of the underground world. An underground river passes through the middle of the city.

The army of Zhenbei city moved forward carefully, and a thousand people acted together. Even if it had the function of invisibility, people would find traces if they were not careful. After all, they were only invisible, such as smell and footprints, which would still be left unless they used spells such as eliminating traces.

The sound of the river obscured Su Lun's advance. After spending more than an hour, Su Lun and the army in the north of the town quietly touched the edge of the grey dwarf city. The grey dwarf's city was first cut out on the rock wall. Later, it was repaired and built with a large number of rocks. It can be said to be very strong.

If you want to capture the city in an ordinary way, you don't have more than ten times the troops and pay heavy casualties. However, for sulun, there is no way to capture here.

Although the wall of the grey dwarf city is high, it is not much different from the flat land for sulun. Several grey dwarf soldiers hide in the leeward of the wall and are sleepy. Su Lun stretched out his hand and pressed it on the rock, ready to use the spell of turning fossils into mud to break a big hole in the city wall.

"Wait a minute," said Hathaway, suddenly holding Suellen's hand.

"Is there a problem?" said Suellen.

"HMM." Hathaway nodded, then stepped forward and groped gently on the wall for a moment.

"This city wall was built with obsidian and element Rune array. The whole city wall is connected," said Hathaway with a frown, "Because of the existence of element Rune array, it is very difficult for these walls to open a gap for mud by relying on fossils, and as long as a pair of walls use magic, the rune array will pass the message to the past at the first time."

"It seems that you can't enter here quietly." Suellen whispered. Then he waved to Karina, "there are several grey dwarves guarding inside. Let's do it together, and then open the gate."

After that, the three simply discussed, and then with the help of flying skills, they successfully flew to the city wall. Because the grey dwarves had no war during this period, their guard was also very lax. On the city wall, there were only two sentries hiding in the leeward to drink and lazy, and several sentries hiding in the next room.

"Vertigo!" * 2

Hathaway gently snapped her fingers, and the two lights flashed away. The two grey dwarfs hiding in the leeward didn't hum, and they would fall down as soon as their eyes turned over. Suellen stretched out her hand to hold them in a hurry, then gently leaned them against the root of the wall, and then waved to them. Karina and Hathaway shot at the remaining grey dwarfs in the nearby small room together.

"Vertigo!"

"Control humanoid creatures!"

Several spiritual lights flashed. The sentry who hid in the room to rest either fainted or was controlled by magic.

Su Lun walked into the room. There was a smell of sweat and a strong smell of wine in the room. For the grey dwarf who liked wine, even if he was on duty, he had to drink a few cups. There were a lot of wine bottles in the room except for some leftover food. Su Lun searched for the key to open the city gate on several people, and soon he found a cloth bag on a strong grey dwarf.

There was a key, two rubies and a book in the bag. Su Lun looked through it and found that it was actually a diary. Does the grey dwarf still have the habit of keeping a diary?

Su Lun looked through it casually. Most of the records are the daily life of a grey dwarf soldier, but some information is revealed in this diary. For example, there are about 1000 people in this grey dwarf city.

And sulun also found out from his diary who was the king of the grey dwarf in the city, and found something better.

"King Thorne is so stingy. We dug out a ruby the size of a fist from the ground. He only gave me 20 gold coins and 10 barrels of wine as a reward. He is far worse than his father soris. We should not support him as king if we knew so..."

"It seems that our grey dwarf king is not loved by their people." Suellen shrugged and put back his diary.

"Karina, let him open the gate with a key."

"Yes, sir." Karina said gracefully, then snapped her fingers. The grey dwarf controlled by her humanoid biological magic came over with dull eyes, picked up the key and walked under the city tower.

With the key, the door of the grey dwarf city is easily opened. The heavy door is opened. Such a big noise must have shocked many people, but it doesn't matter now. Su Lun's army has entered the city. The three-way push tower is close to the highland. How can the flying dragon ride the face lose?

When the city gate opened, the most advanced came barbarians and drow elves. Half of the Centaurs stayed outside the city, and the rest followed in. The large-scale military action immediately woke up more grey dwarfs. Many grey dwarfs had no time to wear armor and come out with weapons.

Su Lun took the lead on a tall black maned horse. It has to be said that the city built by the grey dwarf is very magnificent. The streets of the city are ten meters long, all paved with a layer of stone slabs. In the center of the city stands a magnificent building, which is the palace of the dwarf kingdom.

The building is at least 20 meters high, with a bright magic lamp on the top. Although the whole palace does not seem to have too many gorgeous decorations, it is magnificent and dignified. Next to the palace, there is a temple dedicated to the gods of the grey dwarf, straight and spacious streets, neat stone houses, and simple and practical stone ladders, Dwarf architecture is everywhere.

Before entering the city, sulun had checked the architectural layout of the grey dwarf city through the eyes of wizards, and the drow elves who led the team were also clear. Therefore, after entering the city, they immediately began to implement the plan formulated before. Some people sulun took some people to attack the palace and temple.

The army of other towns in the north city divided all the grey dwarves at the intersection of each street, and then killed or captured them little by little. According to sulun's meaning, the killing of grey dwarves was as little as possible, but they were completely different from those jackals, bear goblins and orcs.

Those jackals and orcs can only work hard or sell to the arena to make money, but the grey dwarves are different. They have exquisite forging technology and are also mining masters. Their combat skills are also good. They are much more valuable than those jackals and orcs. If they can reduce some casualties, they will be reduced.

The grey dwarves were unprepared for the sneak attack tonight. Coupled with the capture of the city gate, many people were panicked. In the face of powerful races such as barbarians, drow elves and centaurs, the grey dwarves had no advantage at all. They were soon killed by the soldiers in the north of the town.

He couldn't fight again. He wanted to escape, but he found that his short legs couldn't run away from the long legs of the barbarians and the drow elves, let alone the four legged centaur. When he saw that there was no hope of escape, he fought desperately and was beaten back directly. Many grey dwarfs had to choose to surrender. These cunning, sinister and selfish grey dwarves have no idea of returning to death.

Su Lun rushed to the palace on a black maned horse with the army. Hathaway and Karina followed closely. All the grey dwarfs encountered along the way were directly pulled out by Su Lun's halberd, and then fainted directly. With Su Lun's legendary strength, there is no enemy of unity here.

Su Lun met some decent resistance when he rushed to the gate of the palace. Fifty dwarf defenders wearing heavy armor and holding axes and hammers have lined up in front of the gate of the palace. The first dwarf wearing gold armor and a sheep horn helmet looked at Suellen angrily with an axe and hammer.

"Humans, you are attacking the city of dwarf King Thorne. If you go back now, I can treat it as if nothing has happened!" the heavily armored dwarf shouted.

"The whole city is going to be taken down by me. I advise you to surrender quickly. I can ensure your life safety." Su Lun smiled.

"You can't think. The people of Dugar are fearless!"

"Really?" Suellen stopped talking nonsense and waved directly, "attack!"

The barbarians and centaurs behind him directly threw the hand axe and shotgun. At such a close distance, the hand axe and shotgun were powerful. Even the dwarf's armor was tough, but it was also hit with dents. Some unlucky people were stabbed by the shotgun, and the gap in the helmet was instantly shot.

Although some were not injured, they retreated two steps after being hit by the huge force carried by the throwing gun and hand axe, and the original neat formation became scattered in an instant.

Su Lun took the lead and rushed directly. The purple dragon halberd in his hand was surrounded by dazzling lightning. Before rushing to the array, the purple dragon halberd swept away. The three dwarf soldiers in the front row flew out directly, and their bodies were entangled by the power of lightning. Although the metal armor had good defense, it had almost no defense against the amount of lightning power, All the enemies lost their combat effectiveness when they were hit by Su Lun's Purple Dragon halberd.

See sullen invincible in the array. The leading dwarf roared, waved his axe and hammer and rushed up, but the dwarf was a chicken thief. He didn't attack Su Lun, but cut back the black maned horse with an axe. If he was hit, even if the black maned horse was produced by the system, it would be finished.

At the critical moment, Su Lun clamped his horse's belly, and the black maned horse retreated. At the moment, he kicked back. He just escaped the dwarf's attack, and a hoof kicked him in the chest and kicked him far away.
