Chapter 659 Dungeon

[Shock Shield] - Use high-frequency sound waves to form a shield around the target, reducing the effectiveness of enemy attacks.

[High Frequency/Low Frequency]: Emits high-frequency sound waves in a small range, causing indiscriminate damage and stun effects to surrounding units; emits low-frequency sound waves in a large range, causing indiscriminate slowdown effects on all units.

【Command Aura】——Enhance the basic attributes of nearby friendly forces.

[Revenge Implosion] - Causes a strong sonic boom inside the enemy, causing huge damage. This skill has a chance to kill the target directly. When this skill is used against a target that meets the "Revenge Condition", the chance of an instant death effect increases.

Compared to Vivian's treatment as a demon king.

Levi's four skills obviously don't have such outrageous effects.

However, apart from the dungeon-oriented command aura, the other three skills are also very consistent with his awakened memory.

Especially the ultimate skill [Revenge Implosion], which is almost a skill specially designed for him to take revenge on the Aberrant.

It is enough to see the hatred this man has for the Deviants.

After using up the two hero quotas of the [Underground Fortress], Lindsay was temporarily out of work.

He asked about Tieyu's care for the wounded.

After confirming that the medical system was functioning normally and that there was nothing she needed help with, Lindsay went to the Zerg to deal with the bodies of the mutants, while collecting prey materials in the flower fields.

On the ground, the sun rises and sets.

The underground world is illuminated by torches, maintaining an unchanging atmosphere.

Wait until a whole day has passed.

The upgrade progress bar of [Underground Fortress] has been completely completed, and the city has officially upgraded to the [Dungeon] era.

Rumbling--

The evolution of this civilization is extraordinary and is not inferior to the [Forest City].

A day ago, the simple rock building structures were replaced with more solid and corrosion-resistant granite. Sculptures and murals such as minotaurs, harpies, or underground black dragons became common in the city.

At the same time, after becoming a [dungeon].

The improvements brought by civilization level are not limited to buildings.

Along with violent underground roars, hard and regular basalt bricks began to emerge on the walls of the cave that originally housed the city.

They form defenses and civilizations, turning this place into a real dungeon.

Rather than the cities in caves like in the past.

Above the dome, at regular intervals, there are fluorescent stones emitting illuminating light.

Unless you are indoors, you can save on torches when walking on the streets of the dungeon.

At this moment.

Lindsay happened to be in the square in the middle of the city.

He felt something and turned his head to look.

"..."

"hehe."

Lindsay's face showed an expression of "as expected".

After the upgrade, the city hall of the [Underground Fortress] also changed its appearance. The smooth and hard obsidian was built into an underground castle!
Right in the central hall of the castle, a majestic, straight, pitch-black staircase extends down and connects with the city streets. Its sword-like straight structure looks like a long sword crossing the earth.

End of field of vision.

Between the thick and majestic Doric columns, under the blood-red flag fluttering in the wind.

A hideous throne made of human skulls sits in the dark castle hall.

The smell of blood and power emanates from this throne.

Lindsay was standing on this side of the square. As soon as he looked over, his instinct told him that this was not a place where serious people would stay.

"This has truly become the Devil's dungeon."

Lindsay chuckled subtly as she opened the building list. [Devil's Castle]

"..."

"Kill enemies, absorb their soul power, and then use it to summon undead and demons."

In the third stage of [Dungeon], the core resource is the soul power after killing people.

It is indeed not ordinary evil.

However, Lindsay has been through so many things that she has long since let go of this problem.

"The key to good and evil lies in the user."

"As long as we can control this power and use it in the right direction, there will be no problem!"

Confirmed the situation.

Lindsay walked to the central square in front of the Demon King's Castle.

He ordered Vivian to call the soldiers and commanders in the city and gave his first speech in the [Dungeon].

"Everyone, you can see the changes in the city now!"

"This is the second city for humans that I plan to build after the Forest City! Your work here will change from conquering and expeditionary forces to maintaining the normal development of the city."

After more than half a year of fighting together, Lindsay didn't need to waste time communicating with the soldiers. He just needed to state his purpose simply.

Only the vengeful Levi in ​​the crowd saw it differently.

He started to get anxious when he heard this, and even took the initiative to ask:

"Lord Lindsay, what about this expedition?"

"We are clearly on the verge of success. We can't, we can't just stop here!"

Lindsay nodded slightly, and then told her own arrangements:

"A week later, I will continue to march north with the Zerg supporters."

"This will be the base camp for the final crusade."

"So, I'm leaving this place to you, and you must protect the safety of this base!"
