The second prince of the Demon Emperor chasing the sun is not a mediocre person, so he will naturally learn the lesson of the seventh prince of the Demon Emperor from the cloud once.

Not to mention the extra cautious march this time, there was also a mobile force mainly composed of Winged Demons, which quickly moved in all directions.

Therefore, this time, Ye Zhen did not take any risks.

Most of the tricks are used when the troops are insufficient.

The current number of troops commanded by Ye Zhenke in the Blood River Fortress is close to 800,000.

This number is already very sufficient for millions of demon elites to defend the city.

Therefore, what Ye Zhen is doing now is to tightly seal the news.

In war, one is to fight logistics, and the other is to fight intelligence.

Now, what Ye Zhen is playing is to play intelligence.

The great defense of humans and demons on the battlefield has a long history.

Therefore, it is quite difficult for both sides to spy on intelligence, but after so many years of arrangement, the two sides still have a certain ability to spy on each other's military intelligence.

However, in wartime, the difficulty of spying on intelligence increases exponentially.

In the past few days when the second prince of the Demon Emperor was approaching the army, Ye Zhen almost issued the harshest intelligence blockade ban.

Without a military order, the piece cannot be lifted into the air.

If it is found, it will be pursued to the end, no matter what the reason, those who send talismans without permission will be immediately beheaded.

If it is found that the rune is lifted into the air, and the person responsible cannot be found, and there is a team in the place where the rune is lifted, the whole team is confined and punished with three hundred lashes per day, and the same is true for those who have guards, and the whole guard is punished, and those who have a regiment cannot find the person who sent the rune without permission, the head of the regiment will be flailed to show the public.

If a private person uses a small communication to move the formation, he will be immediately killed, and the whistleblower will be immediately promoted to the next level.

At the same time, a joint sitting system is implemented.

If it is found that someone in the team uses a small communication to move the array without authorization, or sends a message privately, if no one reports it, it can be verified that it is a demon spy afterwards, and the team will be beheaded, and the chief officer will be pushed down by three levels, and each will be demoted by one level to retain.

As soon as this most severe military blockade order was issued, hundreds of heads were hung in one day, and the entire Blood River Fortress was full of rumors, and everyone was in danger and extremely nervous.

However, it has also borne fruit.

Unexpectedly, he successfully found three bought demon spies, and also found a shadow demon and succubus who had infiltrated.

This made Ye Zhen break out in a cold sweat, and immediately strengthened his confidence.

No matter how harsh the military law was, it was worth it before the war, and a military law was immediately added.

For three days, no one is allowed to act alone, and no one must act in company of his colleagues in any way.

If a lone actor is issued, he will be immediately arrested!

Three days passed in a blink of an eye, and on May 16, the boundless demon army surged under the Blood River Fortress like a wave, and the low horn of attack slowly sounded.

At the same moment, Ye Zhen, who was sitting in the Blood River Fortress, slowly got up and said softly, "Order all departments to act according to the plan!"

Almost at the same time, more than a dozen runic lights rose into the sky and scattered in all directions.

Under the Yangmen Fortress, half of the 200,000 demon army is attacking the city with all its might.

In the intelligence of the second prince of the Demon Emperor, the defenders of this Yangmen fortress are only 100,000, and half of them are militiamen.

According to the plan, as long as the defenders here are in decline, the second prince of the Demon Emperor will allocate additional troops when chasing Hitachi, in order to conquer the Yangmen fortress in one fell swoop.

Stimulated by the order not to seal the sword after the city was broken, the elites of the demon clan rushed to the Yangmen fortress with blood-red eyes and roaring against wave after wave of arrow rain.

Especially those ironclad demons, the aura around them flickered, even if dozens or hundreds of crossbow arrows of beacon fire and crossbow bombarded them, they only flashed in the firelight, unscathed.

Rows of ironclad demons hung huge shields, holding them at the forefront, constantly charging towards the Yangmen Fortress.

Seeing that he was about to climb the city wall, the roar of the sky-breaking dragon crossbow bolts as thick as a child's arm sounded, stringing up rows and rows of ironclad demons, and then exploded into pieces.

This was followed by a covering shot from the Flame Spirit Explosive Demon Crossbow that exuded an astonishing aura of flames, instantly emptying the Iron Armor Demon within a radius of a kilometer.

But as soon as this part of the Iron Armor Demons was emptied, a group of Iron Armor Demons immediately rushed up.

"Assault!"

In the midst of the roar, a group of five hundred Realm King Realm elites, led by two Dao Realms, rushed towards the Yangmen Fortress in the interval between the bombardment of the Heaven Breaking Dragon Crossbow and the crossbow arrows.

"Really, when we're rookies?"

The generals under the command of He Qi, the first fierce general of the Northern Theater who defended the city, sneered, and as soon as the flag moved, it was a salvo of a hundred sky-breaking dragon crossbows, and a thousand fire spirit blasting demon crossbows were fired at the same time, and this batch of elite breakthroughs was immediately repulsed.

The battle was heated at the beginning.

In the first battle, both sides wanted to play morale, banners, and feats, so they worked very hard.

In the blink of an eye, the battle had been going on for more than half an hour, and the corpses were piling up on the Yangmen fortress.

Within an hour, the demons left 10,000 corpses at the bottom, and the Great Zhou soldiers who defended the city suffered at least about 5,000 casualties.

However, the generals of the demon clan are not afraid at all.

Once they attack the city, this casualty gap will quickly catch up and surpass.

In close combat, the sons of their demons are the bravest warriors.

But just when the first wave of ironclad demons forcibly climbed the head of the Yangmen Fortress and launched a tragic bloody city with the soldiers of the Great Zhou Dynasty, the banner on the head of the city suddenly changed, and the big banner of the word "He" began to flutter in the wind.

Almost at the same time, the demon army, the scout's urgent report sounded, "General, ten miles away from the left flank of our army, there is a Great Zhou army, the number is about 100,000. ”

The demon general's face remained unchanged, but he sneered, "Sure enough, as His Royal Highness the Second Prince expected, this surnamed Ye likes to play this hand." ”

"Come on, send a signal!"

Half a quarter of an hour later, the elite reinforcements in the northern theater of the ambush led by He Qi personally started a fierce battle with the demon army.

The demon army that was flanked was not panicked at all, and fought very resolutely, so that the surprise attack did not take much advantage.

In less than half an hour of fierce fighting, the sky suddenly darkened, and a winged demon army with a number of about 50,000 people pounced at high speed, directly rushing to the rear of the He Qi army, and the demon army that attacked the Yangmen Fortress formed a counter-encirclement of the He Qi army.

This made He Qi's face change greatly.

"Send a message to Marshal Ye, just say that the strategy of pincer attack has failed, our army is now being flanked by the winged demon reinforcements that are rushing from the demon clan, the situation is extremely critical, please retreat!"

Soon, He Qi received Ye Zhen's military order reply, but the military order reply made He Qi's face change, "Continue to contain the demon army, reinforcements are coming." ”

"Reinforcements?" This reply made He Qi jump like thunder, "Tell Marshal Ye that if the reinforcements can't arrive within half an hour, just wait for me to collect the body." ”

After a few breaths, the herald brought a military order again, "General, Marshal Ye told us to wait for help with peace of mind!"

"Ready for help?"

These words made He Qi's heart sink vigorously, and suddenly, he had a feeling of being betrayed by Ye Zhen.

He thought, didn't Ye really use his army as a pawn to sacrifice and consume the demon army?

Every soldier under his command is like a brother, and death and injury are inevitable, but if it is.......

In a hurry, a scout who rushed over suddenly cheered, "General, the Winged Demon army has been dealt a fatal blow, and an unknown number of troops have appeared in the rear of the Winged Demon army!"

Hearing this, He Shi's eyes lit up suddenly, "Reinforcements?"

Then, when he lifted off into the air, he opened his eyes and saw a scene that he will never forget.

Ye Zhen stepped out, the silver ripples spread out, and those winged demons who were sweeping like the wind immediately seemed to be drunk, staggering, and their speed became extremely slow.

Then, waves of crossbows of the Beacon Fire Repeater, the crossbow of the Fire Spirit Demon Explosion Crossbow, and the crossbow of the Heaven-Breaking Dragon Crossbow, as if stepping on the rhythm, wave after wave of never-ending pouring down.

The Winged Demon in the sky began to fall like dumplings at this moment.

"It turns out that the battle can still be fought like this, but isn't this a burning of money......." He Qi muttered as he watched this scene.
