Zhenbi Fortress is the largest military fortress located in the northwest of the Beishan Kingdom, which is responsible for reaching the invasion of the Bicao Kingdom, and is also the bridgehead of the Beishan Kingdom's attack on the Bicao Kingdom.

Outside the Zhenbi Fortress, there is a majestic city wall as high as 50 meters high, and 300,000 regular troops of the Beishan Kingdom and various auxiliary units are stationed in the city.

The Bicao Kingdom regards Zhenbi Fortress as a thorn in its side and a thorn in its flesh, and has waged several wars in an attempt to destroy Zhenbi Fortress. As a result, they all suffered heavy casualties in front of the Zhenbi Fortress.

Almost every few years, the Bicao Kingdom would protest to the Beishan Kingdom, demanding that the Beishan Kingdom dismantle the Zhenbi Fortress. Of course, the protest books of the Bicao Kingdom were also treated as garbage by the Beishan Kingdom, and they were casually thrown into the shredder for crushing and flushing into the toilet.

On a hillside far away from Zhenbi Fortress, the eyes of a demon beast Iron Feather Eagle suddenly became more agile, and its wings shook and flew directly into the sky.

"There are a lot of cannon fodder of the Worm Demon Clan!!This is the real Worm Sea tactic, it's really terrifying!"

Yang Fan's consciousness attached to the body of the demon beast Iron Feather Eagle, flew into the sky, and used the [Eagle Eye Technique] to look into the distance.

In the distance, all kinds of demon insects, such as demon beetles, demon scorpion insects, and demon mantis insects, rushed towards Zhenbi Fortress like a tide.

Boom, boom, boom!

The self-propelled guns in the fortress flickered, and countless cannonballs landed among the swarms of demonic insects, blasting countless demonic insects to pieces.

It's just that the demon worms are almost endless, and those pitch-black insect tides that have been destroyed by various artillery fires will soon be filled by countless demon worms.

A terrifying cannonball containing white phosphorus shells was continuously fired into the battlefield and exploded, enveloping the entire battlefield in a white phosphorus flame, burning all the powerhouses of the Demon Zerg Clan.

Although according to the Four-Power Convention, white phosphorus bombs are prohibited weapons for use against people. But against the demon powerhouse, no one cares about this. Those white phosphorus bombs are also one of the best ways to deal with the ground demon insects and cannon fodder!

In the sky, countless flying demon locusts the size of a wild cat with sharp mouthparts flew towards the Demon Suppression Fortress.

From the Demon Suppression Fortress, a series of missiles blasted into the swarm of flying demon locusts and exploded, and the terrifying shock wave spread out in all directions.

Countless flying locusts were blasted to pieces, their wings torn apart by the terrifying shockwave, and they fell from the sky.

It's just that those flying demon locusts are almost endless, and they can't be killed cleanly, and they still frantically rush towards Zhenbi Fortress.

In the fortress of Zhenbi, the various air defense phalanx air defense systems were shining brightly, and countless fires were shining, blasting towards those flying demon locusts, blasting countless flying demon locusts into pieces.

The number of flying demon locusts was too large to kill, and they still formed a terrifying insect tide, flying towards the Zhenbi Fortress.

Once those flying demon locusts fly into Zhenbi Fortress, the entire Zhenbi Fortress will not be far from falling.

"Humph!"

In the fortress of Zhenbi, a handsome man with a tall figure and a white mage robe snorted coldly, and with a wave of his hand, a violent hurricane blew into the sky.

Beside the handsome man stood an ugly man of short stature, ugly appearance, and a bulging face. The ugly man grinned, and with a finger he reached, a yellow poison gas submerged into the hurricane.

The violent hurricane blew towards the flying demon locusts, and countless flying demon locusts immediately fell from the sky as if they had been hit by insecticides, and fell to the ground with painful convulsions.

Yang Fan praised in his heart: "Great Yuan Energy Grandmaster Wind Fang Ning He, Yuanneng Grandmaster Poison Zongtian is nameless!

The Great Yuan Neng Grandmaster Ning He is the Great Yuan Neng Grandmaster cultivated by the King of Beishan, and he is one of the righteous sons of the King of the North Mountain!

Poison Zongtian Nameless was originally an ordinary Yuan Ability, he found out that he was cuckolded as soon as he returned home during an adventure, and then he was framed by the adulterer ** and forced to go to prison. After he escaped from prison, he was lucky enough to swallow a holy fruit to immortalize, and then he had the ability to manipulate the poison, and advanced all the way to the Yuan Energy Grandmaster. He killed the adulterer who framed him**, and affected many ordinary people, but was suppressed by the masters of the royal family of the Beishan Kingdom, and finally took refuge in the royal family.

The skills of Ning He and Tian Wuming cooperated, and they were a perfect match on the battlefield, directly containing the most terrifying flying demon locust.

A burly man in a black robe and armed with a large sword jumped from the fortress and waved his hand.

One by one, summoning magic arrays appeared on the battlefield, and twenty earth-level mid-grade demon beasts with a body length of up to six meters and covered with a layer of cyan scale armor directly appeared.

The tongues of the twenty steel-scaled anteaters burst out and rolled around, directly rolling up the various demon insects that had passed through the fire blockade and swallowing them into their stomachs.

"Yuanneng Grandmaster Xue Heng! Zhenbi Fortress is really as strong as a cloud, it should be able to stop these demon insect armies, right?"

Yang Fan looked into the distance, and at a glance, he saw that the dense and boundless insect swarm was surging towards this side, no matter how the Zhenbi Fortress slaughtered, those demon insect armies seemed to be inexhaustible.

There are all kinds of the most advanced weapons in Zhenbi Fortress, as well as two missile units, and I don't know how many Yuan Neng Grandmasters and Great Yuan Neng Grandmasters are hidden, and their defensive power is extremely amazing. However, once the ammunition of Zhenbi Fortress is exhausted, there is a good chance that it will fall.

After all, the ordinary warriors in the Zhenbi Fortress manipulated all kinds of hot weapons, and they were also the main force to destroy those demon insects. Without the cover of those ordinary warriors, it would be basically impossible for the Great Yuan Neng Grandmaster to defend this fortress alone, even if he had the secret treasure of the Zhenguo.

"No, the most terrifying thing is not that the ammunition is exhausted, but that those demon insects can bypass all kinds of natural hazards and attack the Beishan Kingdom from different places!!"

Yang Fan's heart suddenly moved, a trace of chill swelled, his wings shook, and he disappeared into the sky.

"That's terrible!Those demon zergs are really not stupid!!"

Under Yang Fan's [Eagle Eye Technique], he clearly saw one after another Demon Zerg army bypassing the Zhenbi Fortress, pouring out from the mountains and the sky, and surging towards the heart of the Beishan Kingdom.

The army of those demon insect clans was obviously commanded by a strong man, and they had no intention of storming the Zhenbi Fortress at all, but bypassed the Zhenbi Fortress and went straight to the heart of the Beishan Kingdom.

If this tactic is used by humans, it is undoubtedly self-defeating, and a single logistical pressure can collapse a large army. And the army that goes deep into the hinterland is also easily annihilated by the enemy with superior forces.

However, the army of demon insects is different, they can devour all kinds of plants and corpses as food, and their weapons and equipment are themselves, so they have little need for logistics.
