At this time, Da Liang felt a little confused.

The script opens in the wrong way!

But either way, the undead spawn must be lowered quickly. Who knows how much energy the Wizards Guild has prepared for this magic array, but looking at the refresh speed of the undead at this time, its energy should still be very sufficient.

And the strangeness of this magic array, has it already alarmed the attention of the wizarding guild?

If the letter of introduction of the Holy Bella is not forgiven by the wizard's proclamation, then the Great Light is greeted by a real war.

This was not the time to hesitate, and Da Liang rode Astro to the sky above a refreshed point of the undead.

The "Meteor Shower" is released.

The energy that swept everything swept down from the air, and the meteor fire rain released at low altitude densely covered every corner within a radius of two hundred meters, and in the continuous bombardment of meteorites and fire rain, the undead inside and outside the crater were wiped out, and the fire rain burned everything interrupting the refresh of the undead here, and then a crater was revealed.

A small, glowing magic circle was in the middle of the crater.

The release of the "Meteor Shower" ends.

The undead began to spawn again, but in significantly fewer numbers.

The meteorite's attack had a certain destructive effect on the magic array, but it had not completely destroyed the magic array.

Da Liang landed with three frost dragons, and Astro, Roar, and Hurricane Spit Dragon's Breath quickly wiped out the undead who had just appeared.

Da Liang jumped off Astro's back, and then realized that this magic circle was not improvised, but used alchemy to create permanent fortifications.

The gold and silver metals were refined into wrist-thick strips of metal, which were then forged and welded together following a magic circuit.

The upper layer belongs to the summoning circle, and the lower layer buried in the ground should also have the energy conversion circle and the energy extraction circle.

This combined magic circle is connected to other magic circles through alchemy circuits buried underground, forming a large summoning magic circle.

Da Liang noticed that things seemed to have gotten bigger.

This is definitely not a simple project, and the Wizards' Guild must have invested more in this magic circle than initially thought.

Da Liang felt that he might completely break with the Wizards' Guild by destroying this magic array.

Alas......

I can only take one step at a time and look at one step at a time.

If this magic array is allowed to operate, sooner or later the Black Fire Leader will be attacked by the undead here.

Astro led the frost dragons to quickly eliminate the undead who refreshed from here, and Da Liang took out a shovel to dig down to find the connection point between the upper circle and the lower circle, as long as the energy supply of the summoning circle was cut off, the undead would not come out again.

Da Liang, who doesn't know much about the magic array, can only dig around, and during this time, he has to avoid the attack of the undead who suddenly emerge from his side.

I don't know how many pits he dug up, but Da Liang finally touched a downward metal pipe.

Swing the shovel and smash it desperately at the part where the metal pipe is connected.

one time

Two clicks

……

The metal pipe was finally smashed, and the undead instantly stopped refreshing.

It worked.

A node was destroyed, and the dead pig was not afraid of boiling water, so there was no need to interrupt.

He jumped onto Astro's back, and the three frost dragons flew towards the next node.

The opening of the "Meteor Shower".

After the undead below were emptied, the Frost Dragon pounced into the pit.

The newly refreshed undead were sprayed to the ground by the dragon's breath without any movement, and with an experience, Da Liang successfully found the magic energy supply tube of this node.

Swing the shovel and hit it hard.

A magic node is destroyed again.

Proceed to the next ......

When Da Liang wreaked havoc on this magic array, the refresh rate of the undead in the Buried Bones began to slow down, and when Da Liang destroyed the seven nodes, the entire magic array finally ceased to function.

The undead finally stopped refreshing like a spring, and the undead refresh rate of the entire Buried Bones returned to normal levels.

The sound of the cannon gradually thinned out, and the crisis of the Black Fire Collar was finally temporarily resolved.

The Black Fire Lord's military power became the superior side.

Led by the Skeleton Whipper, the skeletons stepped out of the fortified fortress and went deep into the Boneyard in small squads, tasked with destroying the spawned undead while taking their place to control the entire Boneyard.

In this battle, the skeleton soldiers of the Black Fire Collar suffered 8,000 damage and 200 artillery pieces were scrapped.

Gunpowder consumed 3000 barrels, and shells fired 2000 tons.

The other losses were miscellaneous, and the eyes of the bright ones jumped.

This time, the military expenses were not reimbursed by the university alliance, and they were all paid out of their own pockets, which is distressing!

Enduring the pain in his chest, Da Liang commanded the Black Fire Lord's army to begin to occupy the land of bones.

In order to prevent attacks from the Wizards' Guild, Da Liang continued to strengthen the fortress and build it into a fortress.

The walls of the fortress are ready to be built with five floors.

The outermost wall would be ten meters high, and then five meters would be added to each inward layer, and the innermost wall protecting the teleportation array would reach twenty-five meters.

A large number of turrets and turrets were built between each wall, and there were passages between the walls.

The entire fortress is defended by a drop, and no matter what direction you attack, you have to face a three-dimensional attack from the five walls.

The battle of the Buried Bones made Da Liang realize the power of artillery in the defense of the city, and in this defense system being built, Da Liang is going to place 500 artillery pieces here.

A thousand more light ballistas are also already being manufactured.

In order to prevent a mage from bombarding the fortress from a high altitude with magic similar to the "Meteor Shower", and without the ability to create a magic cannon and a forbidden device, it was decided to use a heavy ballista to deal with those enemies who approached from a high altitude.

In addition to the ten heavy ballistas captured in the outpost manor, there are also 34 lightly damaged heavy ballistas found from the Pudong Fleet Scrap Depot.

This kind of heavy siege equipment, the system city does not sell it to players at all, and Da Liang, who knows the value of heavy ballistas, has been storing these heavy ballistas on Flying Dust Island since they were repaired.

Now that the fortress needs this high-altitude defensive weapon, Da Liang has made Flying Dust Island still maintain the size of ten heavy ballistas, and all the other heavy ballistas have been transferred to the burial ground.

The construction of the fortress is not an overnight thing, Da Liang can only pray, and the wizards' guild will find out later that the magic circle here has been seriously damaged.

Da Liang directs the construction of the fortress, and Astro reports that they have found the Brimstone Mine.

"It's very strange that the location of this sulfur mine is in the center of the entire magic circle, and this is definitely not a coincidence."

When he found that the location of the sulfur mine was really strange, Astro did not rush in, but brought Da Liang to the entrance of the sulfur mine.

It is a downward cavern, about seventeen or eighteen meters in diameter, with a sloping downward passage extending inward.

The inside of the dark cave is not visible, but the pungent smell of sulfur is very strong.
