The central fortress has four floors, with a height of more than fifteen meters, and there are only very narrow shooting holes on the outer walls of the first and second floors, but there are many windows on the third level of the fortress, which, according to Adrian's investigation, is where the captains of the Blackwater Bandits live.

Adrian climbed up the smooth outer wall of the fortress, opened one of the windows, got inside, and pulled the two up with a rope.

Inside the window is a bedroom about five meters wide, which is richly arranged for its time, but the owner is clearly not a hygienic person, and this luxurious bedroom is messy and dirty.

Adrian canceled the stealth, and while she couldn't see Bai Qi and Barrian, she knew the two were right behind her.

She pointed to the bedroom door and made a gesture, and suddenly Barian whispered softly in Bai Qi's ears, it was a spell spell.

With the spell cast, the invisibility effect on Barrian's body was immediately destroyed, and his form was revealed.

The revealing Barian didn't care, low-level invisibility spells couldn't be maintained while using skills, just like the stealth of the Darkwalker.

The sound of the light incantation sounded very simple, only two or three syllables, but in reality the subtle changes were very complicated, and a second later, the staff in Barion's hand pointed towards the bedroom door, and an invisible beam of energy shot down on the doorshaft.

The energy fluctuations quickly disappeared, and nothing seemed to happen.

Adrian pulled slightly, and the door opened silently.

Just now, Barian released a very simple level 0 auxiliary spell "Silent Portal", which is to use arcane power to form a thin layer of energy pad on the door shaft to prevent the door shaft from making a sound when it opens.

Generally speaking, low-level mage apprentices tend to learn offensive spells such as "Scorching Ray" and "Cold Ray", but many experienced full-fledged mages will learn seemingly useless secondary spells, which can be surprisingly effective in special situations.

For example, this "Silent Portal" is very useful when diving in the middle of the night, and it is difficult not to make a sound when the simple wooden door shaft of this world is opened and closed, and the sound of the door shaft will definitely alarm the discerning Chosen Warrior upstairs on such a silent night.

Outside the bedroom was a slightly smaller living room, equally cluttered and filthy in the lavish living room, with stains on the original glossy tung oil wooden floors and food scraps on the dining table and nearby floors, filling the poorly ventilated room with the smell of rancidity.

Once again, Barian cast a "Silent Portal" at the living room door.

Outside the living room is a circular hall with a diameter of 15 meters, and in the center of the hall there is a vertical atrium with a diameter of 5 meters, connecting the various floors of the fortress.

According to the strategy discussed before, Bai Qi, whose stealth effect had not disappeared, took the lead and walked downstairs, and they were going to eliminate the guards guarding the gate of the fortress.

The second floor of the fortress is a circular platform with a width of about less than three meters, the floor of the platform is paved with stone strips and stone slabs inserted into the fortress wall, and the walls around the platform are densely distributed with many trapezoidal shooting holes, the shooting holes are more than a foot wide towards the opening of the inner wall of the castle, while the opening on the outer wall of the castle is only less than two inches wide, such a design not only allows the shooter to have a good line of sight, but also protects the shooter from external long-range attacks.

Under each firing hole hung a heavy pedal crossbow and rows of crossbow arrows.

The circular staircase in the center of the fortress only leads to the second floor, and the first floor is led by two simple wooden ladders, the wooden ladders are very simple tied to the edge of the circular platform on the second floor, it is conceivable that once the gate on the first floor is breached, only need to cut the rope tied to the wooden ladder, the first floor and the second floor can be separated, and the enemies who finally stormed the fortress will find that they are not rushing into the inside of the fortress, but a death trap.

There were four guards on the second floor, all concentrated above the fortress gates, two patrolling with heavy crossbows, and the other two sitting in the corners huddled together and napping.

The first floor is not guarded.

The stealthy Bai Qi and Adrian first quietly touched the platform on the second floor and sneaked close to the four guards, Bai Qi stopped at a distance of seven or eight meters from the guards, he didn't plan to make a move, he wanted to keep the stealth effect, and wait to deal with the two Chosen Warriors on the fourth floor, lurking here, just to prevent Adrian from missing.

When Bai Qi and Adrian were in place, Barian walked down the stairs gently, and since there were only two torches lit in the doorway on the entire second floor, and the two patrolling guards were focused on the outside of the fortress, they did not immediately notice Barrian's presence.

Barian walked briskly down the stairs, and after gaining a good view, he stopped and began to chant a mantra softly.

The chanting was very soft, but it was still clear in the silence of the room, and the two patrolling soldiers immediately turned their heads alertly and looked down the stairs.

Perhaps it was because Barrian's soft chant was not threatening, or maybe they took it as a soft call from some of their companions, but neither guard was the first to make a sound.

The mage casts spells that have already been prepared very quickly, while Barrian, who has the talent for precision, is even faster.

A second later, the staff in Barian's hand flicked towards the location of several guards, and an invisible energy exploded around the guards, turning into a strange cloud of arcane energy that enveloped a radius of six or seven meters around several soldiers.

One of the guards seemed to sense something was wrong and opened his mouth as if asking something, but did not make a sound.

The guard was taken aback by this strange circumstance, and he opened his mouth again, but still did not make a sound, making him think that he was suddenly deaf.

The guard grabbed his companion in a panic and said something loudly, but his companion saw that his mouth couldn't stop opening and closing, but he couldn't hear a sound, and couldn't help asking, "What did you say?" But he was horrified to find that he could not hear his own voice at all.

Just as the two guards were panicking, a black-red light flashed, and a figure suddenly appeared behind them, and the two three-edged bayonets in his hands silently stabbed towards the back of their heads at lightning speed.

The scene in front of them looked like a silent movie, the bayonet was fierce, but it silently pierced the back of the heads of the two, and the surging dark divine power made the two open their mouths and let out a silent scream, but the dark divine power quickly destroyed the nervous system of the two, causing them to fall heavily to the ground, and the violent impact even made a cloud of dust on the ground, but did not make even the slightest sound.

The brutal battle that was close at hand didn't even alarm the two dozing guards a few meters away.

This qiē was the effect of a first-level spell "Silent Enchantment" released by Barrian, although he had heard Barian describe the effect of this spell when discussing tactics before, Bai Qi was still surprised by the magical scene in front of him.

Adrian was already accustomed to this qiē, she held two bloody bayonets in her hands, did not hide the sound of her footsteps, walked to the two dozing guards, both arms flashed a dark red light at the same time, the terrifying power generated by the dark hand skill, the double thorns from the temples of the two unlucky ghosts, fiercely into their cranial cavities, the dark divine power gushing out from the tip of the bayonet quickly destroyed the brains of the two, after a silent scream, the two unlucky ghosts lost their breath for a while convulsions.

Having killed four soldiers, Adrian waved his hand, and the three of them quickly returned to the third floor.

According to the strategy discussed earlier, Adrian, who activated the stealth technique again, was the first to go up the spiral staircase to the fourth floor.

After Adrian walked up for about ten seconds, Bai Qi also walked up the stairs lightly.

The whole fortress is about fifteen meters high, the diameter of the first to third floors is fifty meters, and the diameter of the fourth layer is four or five meters larger than that of the first to third floors, forming a large head at the top of the fortress.

When he was below, due to the dim light and the distance, Bai Qi did not find the reason for such a big head in this fortress, and it was not until he ascended to the fourth floor that he understood the intention of this design.

The entire fourth floor of the fortress is an empty hall, in the center of the hall is a staircase patio with a diameter of five meters, the spiral staircase leads only to the fourth floor, and above the patio is hung with hinges a circular iron fence larger than the patio, and a circle of iron locks is installed on the stone floor around the patio.

Behind the open space four or five meters wide around the patio were densely packed weapon racks, most of which were empty, but a third of the weapon racks were placed with weapons, armor, bows, crossbows, and barrels of arrows, and these remaining weapons and armor alone were enough to arm four or five hundred people.

Behind the weapon rack is a circular passage more than ten meters wide, behind the passage is the outer wall of the four-story hall, on the outer wall of this circle, there are not only trapezoidal shooting holes facing the outside, but also many trapezoidal shooting holes facing directly below on the ground against the wall, because the diameter of the fourth layer is two or three meters larger than the three floors below, from these shooting holes facing downwards can control the entire fortress wall.

On the north side of the hall on the fourth floor, that is, in the direction of the castle gate, there was a table, and three Chosen Warriors with surging qi and blood fluctuations were sitting at the table, talking and laughing in a low voice, and in front of the three of them placed a few plates of leftover food and a large vat of ale.
