This is the typical undead attack pattern.

There are no schemes, tactics, reconnaissance, or temptations, and the army is directly attacked.

Now Da Liang has encountered the attack of the Sea of the Undead, and the higher and higher corpse wall reminds Da Liang of the scene when he attacked the entrance of the stone cave.

The undead must be prevented from continuing to pile up the wall, or they will be able to jump directly into the teleportation circle from above when they gain a height advantage.

However, Julian and the Frost Dragon were only able to maintain a line of this range, and had no energy left to push the battlefield outward.

"The skeleton soldiers came in two thousand-strong teams, and then sent all the stored stones inside."

Under Da Liang's order, a large group of skeleton soldiers emerged from the teleportation array.

Da Liang quickly threw the first brigade of skeleton soldiers into the battlefield, and cooperated with the archangel and the frost dragon to push the battle line outward thirty meters, past the corpse wall that had just formed, and formed a ring of defense with a diameter of 80 meters.

Daliang's skeleton soldiers are also low-level soldiers, even if the team is equipped with a lot of skeleton whippers to improve the combat effectiveness of skeleton soldiers, skeleton soldiers are still cannon fodder consumables after all.

A brigade of skeletons thrown into the battlefield was rapidly consumed.

A group of skeleton soldiers followed in with a batch of stones.

"Build a wall around the battle line just now, and another skeleton brigade will come in."

Da Liang assigned a team of 1,000 skeleton soldiers to carry stones to build the city wall, and at the same time, a group of skeleton soldiers built forts and arrow towers in the inner circle of the city wall.

A team of 1,000 skeletons was also sent in to replenish the damaged skeletons on the front.

Then let those temporarily idle people drag back the corpses of the dead and throw them into the teleportation array, and the personnel on the Black Fire Lord's side will transport these corpses away and throw them directly into the sea.

However, the skeletons were not able to keep up with the number of deaths on the front line, and new corpse walls were piled up again.

Julian and the Frost Dragons have reached their limits to maintain their current line with skeletons, and if they push outward, it is easy to have holes that the ultimate creature cannot fill in time.

"All the combatants stepped back five meters, and another squad of skeletons came in."

In this short encounter, Da Liang could feel that these undead were not led by heroes, and their combat effectiveness was not high, and the same skeleton soldiers, the skeleton soldiers of the black fire collar were under the bonus of their respective commanders, and there was no problem in fighting three or four skeleton soldiers of the same level at a time.

But the real horror of the Sea of the Undead is their number, all of them are undead, I don't know how many there are, no matter how big the difference in combat power is, as long as the opponent is counterattacked in one blow, very few become many, and it also makes Da Liang's skeleton soldiers quickly consume.

A brigade of skeletons, a brigade of skeletons into the battlefield.

In the resistance of the refueling tactics, the skeleton soldiers behind finally raised a circle of walls two meters high.

The fort was connected to the city wall, and the artillery that came in later was pushed up the fort and pushed against the outer extension of the city wall.

"Boom, boom, boom......"

The fury of the artillery resounded throughout the battlefield, and the scattered bullets fired from the muzzles of the guns swept away the undead.

More and more artillery began to cover the tide of the undead, and soon a blockade was formed on the perimeter of the city walls.

The charging undead suffered a large number of casualties on the blockade belt, and the troops fighting the undead on the front line suddenly felt a lot less pressure.

Immediately afterwards, the six-meter-high arrow tower was also completed.

Da Liang scanned the entire battlefield, and for the time being, he found no enemies with long-range attack capabilities, and he did not see flying classes.

"Monica enters with a magic mage."

Monica enters the battlefield with the Black Fire Lord's ranged troops, and the Magic Mage climbs the towering Arrow Tower, and groups of demons roam around the Arrow Tower, providing the Magic Mage with energy tides to enhance their attack power, and beware of possible attacks from flying undead creatures.

Raise the entire battlefield arrow tower, allowing the magic mages inside to attack the undead farther away.

The basic lethality of the magic mage is used to kill these low-level undead, which is a great waste, not to mention that with various blessings, the damage dealt to the low-level undead is exponentially overflowed.

With archangels, frost dragons, and skeletons in the near range, and artillery scatter in the midrange, Da Liang did not let the magic mages attack those low-level undead creatures.

Now that the war has been fought, the giant undead that had been refreshed in the distance have approached the center of the battlefield.

These are the necrons of large beasts, larger and stronger than low-level skeletons and walking corpses.

Necromantic bears and bone mammoths, all kinds of large undead, are moving at full speed, and all the undead in front of them are knocked into the air or trampled over.

In the Wave of the Undead, the large undead violently slammed into a path, and then let out a "hiss" roar and charged at the "invaders".

However, they were greeted by bundles of energy balls.

Even the strongest undead creatures could not withstand more than two attacks from the magic mage, and those undead who seemed to be so powerful that they had reached the height of their bodies fell one by one.

However, death does not threaten the undead, and no matter how great the damage is and the strongest enemy is faced, they will not stop attacking once they are attacking.

This war of invasion and counter-invasion continues to be fought, destined to end in the defeat of one side.

Melee, medium-range, long-range, the Black Fire Leader army has preliminarily completed a defense system, and the better the medium-range and long-range fighting, the lighter the pressure of melee combat.

Several more batteries were built, and new artillery was pushed up the walls.

The gunners assigned by Da Liang have all served in the Black Fire Fleet, and they are very skilled in handling artillery.

Clearing, charging, loading, and firing cannons, there is no time wasted in between, and the places where the artillery attacks are all places where the undead are concentrated, and a piece of the cannon is like cutting wheat.

The number of undead who rushed through the artillery blockade was greatly reduced, and Da Liang threw himself into a skeleton brigade, pushing the battle line forward by 50 meters.

Then a large group of skeleton soldiers drove the skeletons out of the city wall with stones, and continued to build the new city wall in the circle painted by Da Liang, and the gun emplacements and marksman towers under the protection of the new city walls also began to be built.

And the original walls began to be raised.

The war continues, and the indefatigable undead meet the indefatigable undead, and the two armies of the undead start a non-stop offensive and defensive battle.

The Black Fire Leader fleet, which has multiple strike capabilities and construction capabilities, relies on the city defense system to expand the scope of its occupation step by step.

During the three-day war, Daliang took the teleportation array as the center and established three sets of internal and foreign city defense systems.

The inner ring wall is six meters high, the middle ring wall is four meters high, and the outer ring wall is two meters high.

The entire city wall was densely placed with roaring artillery, and the 200 artillery pieces that Da Liang had reserved for himself from the eliminated artillery of the Pudong fleet were all put into the city defense system.
