While the reinforcements sent by Da Liang to the Advance Fortress were still on the way, Shi Fei had already launched a tentative attack on the Advance Fortress.

The Golden Dragon and the Green Dragon led the Pegasus Knights to carry out a deterrent forward pressure from the air, and at the same time conducted high-altitude reconnaissance of the advancing fortress.

At this time, the forward fortress had formed a complete defensive system, with cliffs on three sides and a hillside on one side. The edge of the cliff was built with a high wall, and a castle was built on the top of the hill, and a large number of ballistae of various types were laid out on the platform at the top of the castle and in the shooting holes around it, forming an anti-air defense position, which could provide fire support over the entire advancing fortress.

The hillside has been leveled and leveled, without any dead spots and concealment, and the attacker will be covered by the defender's various long-range fire as long as they walk up the hill.

The dimensional portal is located on the hill wall diagonally below the castle, at the heart of the anti-air defense, and dozens of catapults are arranged in front of it. It is used as a concentrated position for heavy long-range firepower, and is responsible for the fire support of the entire battlefield.

Dimensional portals are fanned down with small defensive strongholds, each with artillery, ballistas, and a large number of skeletons.

Shi Fei observed the entire fortress defense circle from the air, and sighed in his heart: With such a luxurious and intensive use of war equipment, when did the undead clan become so rich! At the same time, he also thinks that he has finally caught a big guy this time.

The tactic that the undead are good at is the Sea of Skulls, but this hill position cannot exert the power of the Sea of Skulls, and if you want to defend it, you must build such a defensive fortress and use war equipment to make up for the weakness of the undead's long-range firepower.

The more the undead invest in this fortress, the more valuable it is that they are protecting. Shi Fei could now determine that the Forgotten Hill opposite the dimensional portal contained the main force of the cyan coalition in the jurisdiction of Sigh City, and they were looking for an opportunity to start a rebellion.

This is the name of the befriending of the sorrowful monarch.

Shi Fei immediately contacted the staff department of the Juggernaut Legion: "Do you have any good plans for attacking such a defensive system?" ”

The staff officer replied: "The position of this undead fortress is easy to defend and difficult to attack, and a large number of war weapons are used, if you attack from the front, you can only rely on war equipment and magic cover, and slowly dig tunnels and build bunkers to advance layer by layer, so that it is the safest to fight...... We can take this fortress at the cost of some casualties.

But this is based on the fact that the other side does not have reinforcements.

We don't know the full strength of this army of the undead, and it's hard to make a more accurate deduction of the war. ”

Since Shi Fei believes that this is the cyan coalition army, then the other party must have reinforcements. Shi Fei didn't think about a full-scale confrontation with this cyan coalition army, his purpose was just to get evidence.

"We don't need to wipe out this undead army, the goal of this battle is to enter the dimensional portal and use the magic ball to record the images inside.

We don't fight a war of attrition with them.

At the beginning of the general attack, a frontal assault, a three-sided sneak attack, and air pressure will pull all the forces of the defenders into battle in the shortest possible time, and then let the air combat unit of the dominant legion assault the plane portal.

As long as the key evidence is obtained, the whole army will immediately retreat. ”

"Yes, Legionnaire! We immediately prepared a plan for this operation. ”

A new battle plan is being formulated, and Shi Fei's dragon star elven army has begun a tentative attack on the advancing fortress.

Elven archers and dwarves cleared the undead sentries and troops outside the fortress, and a brigade of centaurs launched a charge towards the fortress on the hill in five skirmish lines.

The catapult erected in the rear threw the bundled ...... Golden Bomb No. 1.

The Golden Bomb No. 1 spread out in the air, and after landing, it exploded one after another, setting off patches of smoke and dust to cover the charge of the centaur brigade.

The attack launched by the dragon star leader was immediately met by the defenders, and for a while, the cannon rumbled, the arrows rained down, and the same cluster golden bomb No. 1 was also thrown, and the dense explosion blew the charging centaurs to the ground.

What a luxury!

Shi Fei didn't expect the defenders to use such a degree of long-range firepower in the face of the centaur attack, especially the alchemy bombs, the defenders not only used catapults to throw, but many of the spears fired by the ballistas were also tied to the Golden Bomb No. 1 produced in the Misty District of Sigh City.

The centaurs were beaten and retreated, but they did their duty, testing the long-range firepower of the defenders.

It's very strong, it's beyond Shi Fei's imagination. If the Dragon Star Leader is unable to form sufficient fire suppression during the official offensive, it will be difficult to put enough pressure on the defenders and create opportunities for the assault troops.

More siege equipment needs to be added, and these can be purchased locally through negotiation with Palm City, but ...... Alchemy bomb.

At present, the best alchemy bomb on the market is the Golden Bomb No. 1 produced in the Misty District of Sigh City, which is easy to carry and transport, and is an absolute bestseller among players.

The price of a Golden Bomb No. 1 is 500 gold, and 100 pieces were thrown out just after a test attack on Long Xingling, and the total number of Golden Bomb No. 1 brought by Shi Fei this time was less than 2,000. Seeing that the undead on the opposite side threw the Golden Bomb No. 1 so unambiguously, Shi Fei felt that the batch of Golden Bomb No. 1 he brought seemed to be a little insufficient.

At least 10,000 more are needed.

Shi Fei planned to start with a general attack and end the battle within two days. If you want to suppress the defenders' long-range firepower, you need to have enough bombardment.

Catapult throwing, aerial dropping all need to be Jinfeng No. 1.

After the attack time is pressed, the Alchemy Bomb must be replenished.

The origin of the Golden Bomb No. 1 was the Misty District of Sigh City, and Shi Fei immediately ordered his liaison in the Misty District to place an order with the alchemy shop that sold the Golden Bomb No. 1. Alchemy Bombs cannot be placed in the player's backpack, making them a little more cumbersome to transport.

First of all, Shi Fei wants to send a group of players with flying mounts to reach the realm of the dead through friendly player undead territory. Then through the teleportation between cities in the Dead Realm to the Misty Zone of the City of Sighs, the player returns to the Overworld with the Golden Bomb No. 1, and then enters the Dream Realm through the Dragon Star Realm, and finally teleports to Palm City through the city.

If you can use the Clan Gathering Flag well during this period, the transportation speed can be a little faster.

This is also due to the fact that the Golden Bomb No. 1 is easy to carry, and if it is a normal alchemy bomb for catapults, the player cannot carry it and can only transport it by road, which is too slow.

Even so, it will take at least two days for Shi Fei to complete the procurement and transportation of this batch of Jinbang No. 1.

The purchase cost of 10,000 pieces of gold bomb No. 1 is 5 million gold, and the transmission cost during transportation is also hundreds of thousands of gold.

However, the benefits of the war cannot be measured by money, so Shi Fei quickly allocated this amount and urged the logistics department to use the most effective way to transport this batch of Jinfeng No. 1 to the front line.

Monica saw the whole battle in the hilltop castle, and it was obvious that the enemy was just initiating a temptation, but it was a bit surprising that the opponent used the Golden Bomb One in the battle.

Then she received the news that the Black Fire Collar was located in the Misty District, and the alchemy shop had received an order for 10,000 gold bombs.

"It seems that the enemy is preparing to fight a bombing war with us, and we can only accompany them to fight this for the sake of the sales of the Golden Bomb No. 1.

Inform us that all reinforcements are on standby in the Forgotten Hills, and that all soldiers above level 7 in the forward fortress will retreat to the castle.

The siege equipment in front of the city has been doubled, and it is not allowed to use the Golden Bomb No. 2, and all the Golden Bomb No. 1 will be used.

The purchase price of our Golden Bomb No. 1 is 100 gold, and this time someone has paid for this military expenditure, so we will use it hard. ”
