Li De stood on the wall of this city named Gray Stone Fortress and looked into the distance with a solemn expression, as if he was waiting for something to come.

The underground world is dimly lit, as if a veil has been cast before the eyes.

In the wetland in front of the gray stone fortress, all the twisted plants half as tall as a man have been cleared away by the army.

The dark ground, like a rotting corpse, was filled with the smell of rotting plants, which made people sick.

The wind blew from afar and roared away from the cave behind. The whistling sound was like the whisper of a devil.

The gray stone fortress where Li De is located is the main fortress. The city wall is 35 blades high and 15 blades thick. It is enough to accommodate a large number of troops to guard it.

Every 30 meters or so on the city wall, there is a 10-edge tall tower made of gray rock. The tower is divided into three floors, and each floor has dense shooting holes. It seems that deadly arrows may be designed from inside at any time, so that

It scares people.

Through the gaps, you can faintly see the repeating crossbows designed and manufactured by the Magic Industrial Research Institute placed behind each shooting hole.

Most of these modified war machines are controlled by the warriors of King's Blade. The rough-handed orcs don't like this kind of delicate work. Rushing to the front line and bathing in the enemy's blood is what those warriors with hot tempers like to do most.

.

The crossbow arrowhead, which is as thick as a baby's arm, is forged from fine gold mixed with low hills and hills. The concave blood grooves on all sides can increase the lethality and are very aerodynamic. Fine gold, a metal that is easy to break but is extremely sharp, is forged.

Best items for arrows.

Because fine gold is so expensive, few people are willing to waste it.

But Dawn City, which has a rich mine of adamantine, is never stingy in this regard.

The quality of each of these arrows mixed with fine gold has reached perfection★, and even a monster with thick armor cannot withstand it.

At this time, the city tower was almost filled with such expensive crossbow arrows, except for the passageways for people to walk.

In addition to the continuous crossbows, the slinging convoy behind the towering city wall is also surprising.

These catapults have strange green symbols painted on them, and even the switches and various creations are in the shape of pointed ears, giving off a strong goblin style.

The weird catapult is one size smaller than the normal catapult, and the catapult is not loaded with boulders, but alchemy bombs the size of human heads, with green symbols and pointed ear tabs.

Goblin catapults are products of the goblins of the Gray Mountain tribe. Different from ordinary catapults, the only function of these goblin catapults is to throw their alchemy bombs.

These miniature catapults, which are 3 blades long and 1.5 blades high, have a throwing distance of an astonishing 800 blades.

It is a full 300 blades farther than an ordinary catapult - even though it is throwing light alchemical bombs.

But the power of alchemy bombs cannot be compared with ordinary stones. These hundreds of goblin catapults are enough to scare the enemy.

This is the second line of defense of the Greystone Fortress.

In addition, there are twenty tall towers built behind the walls of Greystone Castle.

These high towers happen to be about 10 blades higher than the city wall, forming a staggered gap with the towers on the city wall.

These towers are the third line of defense of the gray stone fortress.

Spellcaster.

Each tower is guarded by a team of twenty spellcasters. These spellcasters can provide powerful fire support for each city wall section, and these towers are carved with magic circles that allow mages to recover magic power faster.

There are not only mages on these twenty towers, but these spellcasters are accompanied by repeating crossbows with greater power and longer range.

These perfect ★★★ quality repeating crossbows have a range of 1,500 blades, which is 300 blades farther than the 1,200 blade range of ordinary repeating crossbows, and the arrows they are equipped with are also perfect ★★★.

Even the three towers in the core area each have an extraordinary-level repeating crossbow, each equipped with 20 crossbow arrows of the same extraordinary level.

These extraordinary repeating crossbows, which are expensive to manufacture, have only one goal, hunting those powerful monsters, and the target level is - level 15.

The tower's firepower point is composed of high-quality repeating crossbows and spellcasters, which can be said to be insurmountable.

Behind these three lines of defense, in addition to large open spaces and rest areas, is the entrance to the underground world.

The originally narrow entrance has been widened and rebuilt, and has now become a huge passage with a height of 20 blades and a width of 50 blades.

The distance about 500 blades inward from this passage was originally an underground space with a width of 1,000 blades. The construction department used this as a basis to expand it again. Currently, the length and width of this irregular underground space exceeds 1,500 blades.

This huge space is used by Tibetan soldiers. In the eight months since Li De was away, the breeding farms have been expanded to 10. Based on this, the number of magic bats has also increased to 6,000.

Among them, 4,000 Magic Bats were classified as Wings of Dawn, 2,000 cooperated with human soldiers to become Magic Knights, and the other 2,000 wore the third version of the bomb-carrying armor-Air Force Three, as bombers.

Used by troops.

At this time, the Wings of Dawn are all in place under the command of Ollie. As long as Li De gives the order, these selective troops will smash the enemy with the most ruthless iron fist.

Next to the armory, the Construction Department built 10 warehouses for storing materials with underground passages extending in all directions.

Food, weapons, armor, alchemy bombs, crossbows and other logistical supplies are neatly arranged according to strict classifications. These reserve supplies are enough for 10 fortresses to consume for a month.

Thanks to Li De's emphasis on the underground world, Dawn City has been working hard to build these military facilities during his absence for the past 8 months. Otherwise, he really would not have been able to prepare such complete preparations in just a few days.

.

After three years of development, the current Dawn City has accumulated a number of talents who can be reused.

Especially the intelligence command center and think tank, these two large-scale staff organizations can often identify and correct deficiencies and come up with very good plans.

That's why this amazing scene appeared before us.

"Your Majesty, all soldiers are ready."

Garp, the level 18 orc king, stood behind Li De and reported respectfully. The huge lion's head had been protected by a sturdy extraordinary helmet, and only a pair of cold eyes were exposed.

The tone was deep and solemn.

"There are currently 20,000 orc warriors stationed in the underground world, 10,000 on the front line, and 10,000 warriors in the cave as supplements."

Li De's deep black eyes continued to look into the distance, and he nodded slightly but did not speak.

He was waiting for the enemy to arrive.

The tactics implemented this time were not complicated, luring the cave spiders to attack, and relying on the sharp edge of the gray stone fortress to kill the cave spiders to the greatest extent possible.

The strategic goal in the early stage is to kill as many cave spiders as possible and obtain enough death power for the Bone Burial Ground to hatch bronze eggs.

Of course, this is just the beginning of the plan, his ultimate goal is to occupy the magic crystal veins.

But the number of cave spiders occupying half of the plane is too terrifying. If we just let it go so recklessly, the consequences will be unpredictable.

The City of Dawn is not yet capable of crushing the cave spiders that use half of the plane as their nests, especially when it is unclear how many high-level cave spiders the opponent has.

Therefore, the role of the Gray Stone Fortress is to lure the opponent's high-level combat power to attack, thereby hunting down those high-level cave spiders that may pose a huge threat to the City of Dawn army, and preparing for the next attack by the City of Dawn army on the magic crystal veins.

.

Cave spiders can quickly hatch ordinary spiders in batches, but high-level combat power above level 15 is not so easy to grow.

In Li De's opinion, this is the greatest role of Greystone Castle.

Once this plan is carried out, Greystone Castle will become a veritable meat grinder, where the two forces will face off in the most direct way.

On one side is the primitive and fierce cave spiders that occupy half of the plane and have countless cave spiders, and on the other side is the highly developed City of Dawn, which has super magical scientific research capabilities and production capabilities.

The tip of a needle is facing the wheat awn.

Suddenly, Li De seemed to notice something and narrowed his eyes slightly.

A gray line appeared at the end of his sight, like a sandstorm sweeping in from a distance, covering the entire wetland.

The wind in the air quietly carried a fishy smell that made people feel panicked.

The cave spider is coming.

The closer the line got to the gray stone fortress, the stronger the smell became. All the soldiers' expressions had become solemn at this time. The arms holding the swords and shields were slowly tightening, and the muscles were as clear as steel.

What is particularly eye-catching is that in mid-air ahead, a giant beast with a wingspan of 16 blades and covered in steel armor is flying wantonly in front of a sandstorm composed of countless cave spiders.

Castro, the newborn king, a behemoth wearing extraordinary armor, serves as the key figure in this seduction.

Hiss~hiss~

After entering the distance of Thousand Blades, the cave spider's stinging scream, like a sharp knife scratching across the glass, began to echo in the air.

The orc warriors wearing dwarf armor on the city wall felt a strong pressure coming towards them. Along with the sound that sent chills down their spines, everyone finally saw the gray line clearly.

Spider, a huge spider.

Although these newly transferred orc warriors were mobilized before the war, they had seen cave spiders that were specially captured to introduce them to their weaknesses and tell them how to kill them.

But seeing the magnificent scene of hundreds of thousands of giant spiders running and roaring on the ground is still a kind of heartfelt shock.

At this moment, even human soldiers who had never been on the battlefield felt that their hands were shaking unconsciously. It was an instinctive reaction of the body and could not be controlled at all.

The gray stone fortress was built on the edge of the underground world against the mountain. The wetland in front of it was the outer area of ​​the silt swamp, and the ground was flat.

When this vast land is full of hideous and terrifying cave spiders, the impact on the senses is enough to shock people's hearts. Even a determined warrior will feel tremendous psychological pressure when seeing such a scene.

.

Especially when everyone stands at a high place and can see the scene intuitively, it adds to the feeling.

The cave spiders were like crazy, screaming and chasing Castro desperately.

The distance between Thousand Blades passed in an instant, and Castro accelerated his speed sharply. A wave of air exploded directly behind him, and he reached the city wall in an instant at supersonic speed.

Swipe~ The moment it flew towards the city wall, the body of this giant steel beast suddenly turned into a mini bat.
