"Whoosh! Whoosh! Whoosh!"

From the moment the sword mage took the lead in attacking, the eight thieves standing on the commanding heights of the tunnel on the other side all pulled the triggers and poured poison-quenched crossbow bolts towards Brian, who was standing alone.

"Bang! Bang! Bang!"

When the speeding crossbow arrow approached about half a meter away from Brian, it would either deflect directly and fly in another direction, or it would exhaust its kinetic energy and fall at his feet.

The moment the thieves on the commanding heights finished shooting the crossbow bolts, they didn't waste any time. They all pulled out their weapons, jumped up, and rushed towards Brian, whose protective field was dim.

The moment the four derro dwarves jumped down, they were hit by two consecutive "Arcane Missiles" from Brian. They either died miserably or fell to the ground wailing in pain.

The two derro dwarves who had reached the second level of strength and approached him first with "Shadow Assault" were enveloped by the "Colorful Jet" he had been waiting for for a long time, and fell to the ground unconscious.

——"First-level spell: Krugur Fire Arrow!"

After taking down the six thieves, Brian quickly whispered two spells, and the arcane runes on the staff in his hand glowed with hot red light.

The two short crossbow arrows in his palms, carrying flame energy with tiny crackling sounds, quickly passed through the air and accurately hit the chests of the last two thieves.

"boom!"

With a crackling sound, the flaming arrow exploded in the chests of the derro dwarves, blowing their remains into pieces.

Brian released several more flaming arrows to kill the thieves who had lost their fighting ability.

At the end of the battle, he looked at the explosion damage caused by the flame arrows and nodded with satisfaction.

In fact, this simple and ordinary one-level spell is not as powerful as imagined.

But he obtained this excellent staff in the red dragon's lair, which can comprehensively increase the damage and release speed of fire-attribute spells.

The spell was buffed with additional damage and explosive fire characteristics, and was strengthened by his battle mage characteristics. When released, it was comparable to a weakened small fireball.

The most important thing is that the spell is released very quickly. He can release two flame arrows in succession in almost one second.

If the spell is not released for too long, you must pause to relieve mental fatigue.

He only needs to rely on flame arrows, which is enough to make most professionals with similar strength to him unable to do anything.

As the battle here ended, Hesiah rushed over with his own rune sword.

Brian could tell from the smiling expression she looked at him that the escaping thief leader had been killed.

He no longer hesitated, and immediately took the sword mage with him, ignoring the crazy and hateful eyes of the Derro dwarf civilians who were looking at them in the dark, and walked straight forward.

"This is the Whirlpool Tunnel, and the derro dwarves' 'Sacred Law Hall' is hidden inside."

Brian glanced at Hesiah and pointed to a crack in the stone wall that was hidden by rags, faded canvas sheets and moldy boxes.

The crack is just big enough for a medium-sized human to squeeze through.

They no longer hesitated and entered the tunnel cautiously.

The Whirlpool Tunnel is a group of caves connected to each other at the bottom of King Aldus City.

It cleverly avoids the mines and streets of the city, because the derro who first discovered it did not announce its existence to the public.

To this day, only the Council of Scholars formed by the derro dwarves and a few people among the gray ghosts truly know of its existence.

The tunnels here have gentle curves but are deep and long, and their tunnel dimensions are relatively uniform and smooth.

There are also rare rock formations and rich natural fungus clusters distributed in the tunnel, and its depths are also filled with leyline radiation.

According to the information from Goblin Copper Block's reconnaissance, he knew that there were currently two independent organizations operating in the tunnel for different purposes.

The Gray Ghost built an alchemy laboratory and a fungus cultivation garden here to replenish the organization's poison supply.

Another demonic cult formed by the Derro Council of Scholars is using the energy radiated by the ley lines to spread chaos and madness throughout the city through evil rituals, using a broken spire as a medium.

Obviously, these derro are trying to weaken the city's power through these means, so that they can overthrow the duergar city.

When the two of them walked out of the tunnel and came to a relatively open fungus forest, the figure of the goblin copper block appeared in front of them.

"Excuse me Taimora, you are finally here." Copper jumped down from a mushroom umbrella and came to them happily on his short legs.

His sudden appearance scared Hesiah to the point where he almost drew his sword.

"Bronze, you continue to follow Jeep. I suspect that he is trying to summon the soul of a crazy killer through bloody sacrifices. If you can stop it, stop it. If you can't stop it, just leave." After Brian saw the figure clearly, there was no answer.

Nonsense, immediately said to the goblin:

"Hesiah and I are going to the 'Holy Law Auditorium' to deal with the people of the Council of Scholars. The task is completed. You can leave on your own. Don't go any further."

"Okay." Copper Block was silent for a moment, looked at Brian, shrugged indifferently, and was about to turn around and leave.

"Wait a minute." Brian stopped him, took out two scrolls from his dimensional bag and threw them to him, "One is a fireball scroll, and the other is a protection scroll. Keep it for yourself."

"You are really extravagant, giving me such a precious thing." Copper Block put the scroll away in surprise, "If it doesn't come in handy, I won't return it to you."

"It already belongs to you. You can do whatever you want with it. In fact, with your strength as a ghost walker, you can achieve wealth and freedom if you are willing. There is nothing to envy." Brian teased him with a smile.

"Tch, let's forget it." Tongnuan'er curled his lips disdainfully, turned around and left them with a picture of his back, waving his hand coolly, and said:

"I am a kind-hearted goblin with principles. First, be kind to others, second, do not steal or rob, third, be friendly and make money, fourth, help those in need, and fifth... forget it, wait.

I'll tell you next time I remember it."

Brian looked at the disappearing figure of the goblin, smiled, and then led Hesiah towards the derro dwarves' 'Sacred Law Hall'.
