The steel golem stood on both sides, and the bronze metal doors were opened slidingly and now locked. The magicians were silently preparing, and the puppets lifted down the small magic cannon, and they arranged a platform in the passage to install the magic cannon.

This sliding metal door is quite thick, with a mezzanine in the middle, and is hard solid wood. The metal wrapped in it is also more than two centimeters thick.

The solid wood inside the mezzanine must have been arranged with a magic circle. If you want to chop with a knife and an axe, it is impossible to open the door.

Corleon was preparing to use a magic cannon to bomb directly, simple and crude.

Corleon and Xia He went down into the passage first and looked at the metal gate. Xia He said, "Don't you do a pre-attack?"

"It seems that there are chaos magic patterns inside, and pre-attack and magic gun attack cannot complement each other. Anyway, it is to consume power, so just use a small magic gun to save your strength."

Xia He looked at the ground and found that it was hard iron mud and stone, which was treated with magic. The ground-breaking technique was not easy to use. Moreover, this was an underground passage, and if it collapsed, the mage himself would be in trouble.

Although the front is spacious, the magicians cannot be placed there. There is really something unexpected and it is difficult to retreat.

Xia Hedao: "It's not that difficult. This kind of portal without counterattack is indeed the best. But let me do something first, you guys are ready."

"Okay." Although Corleon had his own plan, he agreed happily.

Xia He released a puppet. This puppet is quite simple, obviously an immature work, and has also removed many plug-ins. It looks like it has no combat power. Corleon was puzzled, and then he saw that Marquis Asra took something and handed it over to the puppet.

The puppet held the weapon and approached the metal gate. At the front of the weapon, a drill bit popped up and began to rotate rapidly.

The magicians were speechless. The puppet and the weapon were both normal, but the quality of the drill bit was excellent. In the blink of an eye, the drill bit penetrated the outer metal.

If you chop with a knife and axe or bombard with magic, these attacks can be evenly dispersed. However, when the strange drill bit drilled, a hole was directly made into the outer layer of the metal.

Xia Hedao: "You see, sometimes, it will be much easier to change your thinking."

As he said, he directed the puppet, changed his position, and continued to use the drill to make holes. It didn't take long for a while, a circle of holes appeared on the metal gate. At this time, Xia He didn't need to give a guide. A steel golem walked forward, bent down, and banged it up, and a metal shell was sunken, and the connected holes were completely torn apart.

The steel golem reached out and pulled off the entire circle of metal.

The magicians were stunned. They did not understand the principle. Xia He did not explain. Normal Dao Sect's similar defense methods would have counterattacks, repairs, and all solutions to deal with them. They could really only solve the problem by head-on.

The puppet continued to use the drill bit to destroy the outer metal, and then the steel golem went up to tear off the metal that was initially cut by the drill bit.

The gate is seven or eight meters high, and the puppet only handles the two meters below, but it is enough.

Xiahe made the steel golem retreat and released a broken fire hell, burning directly in the lower half of the gate. After the metal skin of this gate was destroyed, its defense against the flames decreased a little. Xiahe's broken fire hell is known for its long burning time. On the battlefield, it can block the enemy's advance and form a natural barrier.

The wood inside the gate is more than half a meter thick and was refined by magic. Even the violent magic flames like Xia He did not ignite it, but the magic pattern inside was weakened. Xia Hedao: "You can observe it and you can almost shoot the cannon to attack."

"Let's exit first, the aftermath of the magic cannon is not a good time," said Colleon.

Xia He nodded, and the magicians left the passage, leaving only those who controlled the small magic cannons. In addition, the steel golem and puppets also retreated. The magic cannons did not distinguish between enemies and me, and as long as they were in front, they would be smashed into scum together.

The passage is also quite spacious, but there is no safe place in front of the magic cannons. After everyone retreated, six small magic cannons lined up roared together.

The magician responsible for the attack raised his shield and was still blown out.

The entire gate was blown away half of it, and the hot temperature of the hole made people dare not get close to it.

Frost World!

Goth lost an epic magic and the temperature was quickly lowered. In order to invade, everyone was willing to damage the magic cannon itself.

The front row rushed out were four steel golems, then twenty combat mages, followed by two hundred armored infantry and core mage regiments. Behind were more than three thousand elite soldiers following.

The human army entered in an orderly manner, and four steel golems rushed into the ground, and immediately hundreds of weapons were thrown over.

There are stone bullets, arrows, hammers, magic...

The body of the golem was immediately covered with scars. Xia He looked at it from a distance and felt speechless. What kind of attack is this? It just broke the skin of the Iron Golem? It was really a skin, just to make the Iron Golem look more beautiful, and then there was no other meaning.

Twenty combat mages rushed in quickly, and the fireballs fired to all sides. Heavy armored infantry followed closely behind. After entering, they found that this was a small square, with an army in front of them, with about a thousand people. The magician who released the fireballs behind the steel golem was not attacked at all.

The heavily armored infantry held a musket and rushed forward, pulling the trigger at the same time, and two hundred magic muskets roared.

Xia He glanced at Corleon beside him and said, "Is this your information?"

Corleon blushed a little, and he didn't expect that the tough underground world would block the inside and outside, but the army was so weak that it was only more than a thousand people, and they wanted to resist their army.

According to the elite level of the empire's army, it is not a problem to hit ten opponents by one person.

Twenty magicians covered the fireballs, which directly interrupted the opponent's attack. After two hundred muskets opened fire, the opponent was completely stunned. The heavy armored infantry did not charge, and more than a hundred people were knocked down in the front row.

Xiahe saw snowmen, dwarfs, and insects! Cavemen! There were even some bat people.

This army is really a hodgepodge. The dwarves and cavemen inside are quite powerful. The batman was almost burned by a wave of fireballs, and he screamed on the ground.

However, the county prince army did not take it lightly and advanced quickly to find a strategic position.

After entering the gate, there is a small square, with a well-connected passage in front of it, but the passage in front is the most spacious, which is behind the underground army.

There were originally high platforms on both wings, but no one was stationed on it.

The human soldiers behind rushed in and immediately assigned a hundred people on their left and right to occupy the commanding heights.

The auxiliary mage released the acceleration technique, and various shields fell on the soldiers. The human soldiers were like wolves and tigers, and almost at the speed of charge, crushing more than a thousand enemies.

Xia He has participated in many wars, but for the first time, the strength gap between the two sides is so big. And this time, the other side has no reserve means.

What is the guy who seized human businessmen?

"Catch prisoners, interrogate them, and continue to advance." Corleon barely calmed down and issued an order. Later, more human troops poured in, and soldiers and auxiliary mages joined forces to fight into the surrounding passage.

However, what disappointed them was that they did not encounter decent resistance.

There were indeed some enemies in these passages, but these enemies did not even have armor and looked worse than human mercenaries.

Xia Hexin said that it was really easy for him to make money. No matter what the enemy was like, he would have made contributions.

But I agreed that the enemy has a very powerful epic? Why didn’t I see any of them?

Xia He was also strange, but he was worried about this. He hoped to find a place where he could station and stay in the camp himself, waiting for the ghosts and gods to collect gold, jade, wood and stones underground. The magicians of the prince also hoped to hold themselves back and not wander around.

Because of the map, the army will give priority to advancing the caves on both sides, and the middle part is slightly slower. These caves are connected to each other. If the middle road advances too fast, it may be attacked by both sides.

However, all caution became a waste of time. When the army pushed into the underground city, they saw the huge underground city, and there were broken walls everywhere, as if they had just experienced a great war.

The number of troops hiding in the dungeon was less than two thousand, and quickly collapsed under the attack of magic muskets.

"Marquis." Corleon also looked inexplicably.

Xia Hedao: "It should be that an accident here. They have no negotiation conditions, so they have a gamble and blocked the door. We hope we can retreat."

Corleon was amused and cried, and said, "I have the life to be with me. Even the abyss ahead must jump into it. How could I leave?"

Xia Hedao: "What do these underground creatures know, they don't even come together."

Only then did Corleon regain a little thinking ability and know that the Blood Mage was right. The civilization in the underground world was backward, and his view on affairs could not be the same as that of the human empire.

In the underground world, sometimes giving up is the means of survival. But once the human empire has a plan, it will only find ways to complete it.

The people in Xiahe did not experience any battles, so he chose to build a camp near the north of the underground city.

He asked his magicians to flatten the original house and build it separately by himself. He looked like he was going to be stationed here for many years, which scared the mages of Lilac Princes such as Corleon.

Corleon was busy commanding everyone, so Goth was sent over.

When he saw Xia He, he asked directly: "Marquis Marquis, are you planning to stay here for a long time?"

"Of course not. I left after the student's trial mission was completed."

"But……"
Chapter completed!
