While at the Military Academy, Cross's mentor taught the defense of cities and fortresses.

The instructor used the Borean Fortress as one of the real cases, and described the structure of the Borean Fortress in detail.

Because of this, Cross is quite familiar with the Borean Fortress.

Bringing the Hofer Clan's Kubobo is to prepare to clear the level and dig a tunnel to enter the interior of the Borean Fortress.

In this way, Cross and his party completely avoided the threat of the enemy army from the tower.

After deciding on the excavation site, Cross and the others dug the secret passage.

At this time, Britney also changed back to her human form, and her dragon form could not squeeze into the narrow secret passage.

The advantages of the Hofel clan were vividly displayed at this time, the strong and powerful little short legs were cutting the soil rhythmically, and the digging speed of Ku Bo was very fast, and in a blink of an eye, Ku Bobo's entire body was already in the cave that had just been dug.

Of course, his body is not very big.

Ku Bobo poked out his round head, glanced around Cross and the others, and said proudly, "You guys are really slow. ”

"Little Hofer, beware of me pinching you to death. "Britney didn't like Kubo, she thought the Hoffil was too rude.

Kubobo shrank his head back in fright, he had the impression that Britney was not so fierce.

Cross stopped what he was doing and said solemnly, "Kubobo, we are only assisting you, and you are the main force in digging this secret passage." ”

True, they did not carry any digging tools, and digging with weapons was too laborious.

"Hahaha, it turns out that I am the key to this battle, so you will reward me when we go back, Lord Cross. ”

"If you dig the secret passage in two hours, I might as well consider rewarding you. ”

"Two hours...... "Ku Bo tilted his head and thought for a few seconds, then suddenly retracted into the secret passage that had been dug a little bit, and began to speed up the excavation.

"We helped to pile aside the dirt that Kubobo had dug up. Cross commanded.

......

Two hours later, Kubobo had dug a secret passage as Cross had instructed.

After passing through the secret passage, everyone came to a dark and damp area.

This place is a dungeon.

Before the construction of the Borean Fortress, it was originally a dungeon for death row prisoners.

Later, the dungeon was abandoned.

And this dungeon is a top-secret passage to the fortress of the north wind.

After entering the dungeon, Cross lit a torch and walked to the front, only he knew the only right path.

Several rats began to flee when they saw the fire.

This dungeon has indeed been abandoned for a long time.

The narrow passage was flanked by rusty cells, white bones eaten by wild beasts scattered throughout, and broken bottles and jars.

"I hope I can get out of here quickly, I hate it. Link, who was sitting on top of Cross's head, complained.

As a wood elf, he certainly didn't like the feeling of being corrupted.

And Ku Bobo, who was not afraid of the sky at all, was scared at this time.

This environment, combined with the dim light, made him feel very uncomfortable.

"Gollum"

Looking around, Ku Bo accidentally kicked over a jar, and a dense number of insects flew out of the jar, and he was so frightened that he covered his face with his hands and screamed.

"Ah!! help!"

"What's the situation?"

Cross, who was at the forefront, immediately stopped and turned around.

"Lord Cross, it's okay, just kicked over a jar. "It was Gargoyle Isaac who answered.

After saying this, Isaac walked over to Kubobo and picked him up.

"Little Hofer, so you don't have to be afraid. ”

Kubobo didn't want to admit his timidity, but he wanted Gargoyle Isaac to provide him with a sense of security, so he puffed out his round face and didn't speak.

After walking some way inside the labyrinthine dungeon, Cross stopped.

He looked at the cross torture frame in front of him and said, "This is it, the exit is above." ”

Everyone looked up, and there was no exit, and it was completely closed.

However, Nia was aware, her little nose fluttering rhythmically, she was sniffing, "The smell of cooked food, this is the kitchen?"

"Nia, your nose is too sensitive, there is such a bad smell here, you can actually smell the smell of cooked food above. "That's right, it's the barracks kitchen of the Borean Fortress." ”

"And how do we get up?" asked Nia.

Cross looked at the stone wall above, "The stone wall directly above the Cross Torture Frame is the weakest point. With that, he turned to Isaac the gargoyle, "It's up to you next, Isaac." ”

"Yes, Your Excellency. ”

"The rest of us spread out a little. Cross said.

Isaac flicked the hammer in his hand and shook his wings at the same time.

Remaining in mid-air, Isaac picked up a sledgehammer and slammed it into the stone wall above him.

"Boom!"

With a loud bang, the stone wall above collapsed, and stones and dust fell with a "clatter", followed by a bright pillar of light shooting from the crumbling hole into the gloomy dungeon.

Cross pulled out the long sword at his waist and said in a cold tone, "Kill." ”

......

Sheehan's defenders left behind at the Borean Fortress were weak in combat, with a total number of no more than 60 men, and most of them were wounded.

Such a force, in the face of Cross and the others who suddenly appeared from inside the fortress, was simply powerless to fight back.

What's more, the locals of the Borean Fortress, upon learning of Cross's actions, picked up the tools of their work and launched an attack on the defenders of Seajarda.

The Seattas soon laid down their arms and surrendered.

However, Cross didn't have the energy to manage the troops anymore, so he killed most of them and deliberately let a few go.

At this point, the Borean Fortress was also included in Cross's sphere of influence.

To Close's surprise, the inhabitants of the Borean Fortress not only did not reject Hofel people like Kubo, but also quickly accepted Isaac the Gargoyle and Hogg the Gnoll.

They think this multi-racial composition of troops is cool.

They also begged Cross to stay in charge of the Borean Fortress.

Cross informs the inhabitants of the Borean Fortress that he has been made Earl of the Klein Territory by His Majesty the Emperor, and that he must completely drive the Seatta invaders out of the Empire in order to fulfill his responsibilities as Earl of the Crane Lord.

He proclaimed the rules and regulations of the forces and the system of rewards and punishments to the inhabitants of the fortress, and encouraged the inhabitants to take up arms and go into battle.

Local residents are also very active.

Soon, a recruit unit of more than 20 people was formed.

In the end, Cross arranged for Isaac the Gargoyle and Hogg the Gnoll to temporarily manage the Borean Fortress.

He led the rest of the men to the south.
