In less than half a day, the seventh prince Congyun and his generals agreed on a strategy to attack the Blood River Fortress.

I have to say that Ye Zhen's previous surprise attack still played a certain role.

Originally, the strategy of concentrating all his efforts, first breaking through the Blood River Fortress, and then crushing the slaughter of the other two garrison fortresses, was slightly changed by the Seventh Prince Congyun and the other generals.

It was mainly Ye Zhen's previous surprise attack that scared them.

Originally, according to their plan, their main force would be concentrated under the Blood River Fortress, and as for the other two fortresses, each fortress would send 100,000 troops to maintain a low-intensity attack, and wait for the main force to break through.

But now, Ye Zhen's three surprise attacks swallowed up the 180,000 troops of their advance army and more than half of the elite, which made the Seventh Prince raise his vigilance from Yunqiu.

If it is said that the advance corps was attacked by a surprise attack and lost three times, it can barely be said to be the pot of the advance corps commander Yuedai.

So if he waits for the soldiers to join forces and succeeds in such a surprise attack, then he, the face of the seventh prince, will really be lost.

In this battle that may decide the successor to the throne of the Demon Emperor, he will lose a lot of points.

Therefore, the Seventh Prince became extra cautious from the clouds.

The very large army that went to the two fortresses separately was still a little weak in the eyes of the seventh prince from Yun.

As a result, the army sent by the Seventh Prince from Yun to the two fortresses increased from 100,000 to 150,000.

In this way, the number of the main forces of the Seventh Prince Congyun was reduced by 300,000 at once.

In fact, if it were possible, the Seventh Prince Congyun would prefer to send 200,000 troops from each fortress, which would be safer.

What made the seventh prince Congyun angry was that the advance army was reduced by 180,000 at once, which made the seventh prince Congyun's originally sufficient troops become nervous.

Especially if there is to be a division of troops.

After the division of troops, the army left for the seventh prince Congyun was only 520,000.

Moreover, the old battalion in the rear needs to send a certain number of soldiers to stay behind, and establish a stronghold in the middle to guard against the surprise attack of the elite troops of the Great Zhou.

In the end, the army that could be concentrated under the Blood River Fortress was only 450,000.

According to their information, the total number of troops in the Blood River Fortress is between 150,000 and 180,000, and if it is an ordinary demon army, even if there is a number of 450,000, it is very difficult to capture a military fortress like the Blood River Fortress.

Fortunately, this time, the army brought by the Seventh Prince from Yun was all the elite of the elite.

In terms of combat power, it is at least twice as large as the advance corps.

In this way, it was able to make up for the battle losses of the 180,000 advance army before, so that the seventh prince Congyun had the confidence to conquer the Blood River Fortress.

The Seventh Prince's army from Yun came from afar, and he was also a little tired, so he needed to rest and recuperate, but at most, it only took half a day.

But what's even worse is that the advance corps has lost three games in a row, losing troops and losing generals, and the soldiers are sluggish, so they also need to adjust and improve their morale.

Therefore, as a last resort, the army of the Seventh Prince Congyun could only rest in place.

And this is also the meaning of Ye Zhen's previous surprise attack.

The first is to buy time for reinforcements, the second is to weaken the enemy's forces, and the third is to increase the pressure on the enemy, so that the enemy has to increase the division of troops and weaken the defensive pressure of the Blood River fortress.

These are the three strategic goals that Ye Zhen set for himself before the surprise attack.

Now, it's all done.

On January 17, the demon army under the command of the Seventh Prince Congyun was divided into three rolling oolongs, and they pounced on the Blood River Fortress, Yangmen Fortress, and Cairo Fortress respectively.

For a time, in the defense area of the Blood River Fortress, warning signs flew all over the sky.

The Great War is coming!

At the same moment, in the large mountain ravine to the left of the Cairo fortress, the north wind was whining, blowing the snow foam on the ground and bringing a whirlwind of snowflakes.

If you look closely, this snowflake whirlwind is still changing.

One moment it will change into a grimace, another will change into a fat and unshapeable human face, and another will change into a slender figure like a yaksha.

This snowflake whirlwind is like a living one, and if someone comes here alone, I'm afraid the soul will be scared away.

Extremely suddenly, within the snowflake whirlwind, there was a sudden sound of a dense explosion of whip twitching.

The moment the dense explosion of the whip twitched sounded, the snowflake whirlwind twitched violently like a human, and then disintegrated in an instant.

"Ugly, are you itching?"

"Let you set up a little illusion, you are going to make some trouble? If your skin is itchy, just say it, I'm bored these days!" The little demon's cry mixed with fire rang out.

"If someone happens to see through it and ruin my father's plan, see if I don't kill you!"

The voice of the little demon made the entire illusion tremble slightly, "Big sister, I'...... Am I not bored?"

"Besides, if you and Big Ears don't monitor the enemy's movements, how can it be exposed?"

"Dare to slam your mouth!"

The little demon's screaming voice made the mirage Yuanling Ugly extremely reluctant to sue Rao, "Big sister, I know that I was wrong, I won't dare in the future!"

This guy has a stinky mouth and a lot of bad ideas, but he is still quite practical.

"Don't let me find out next time!"

With a cold snort, the little demon's breath disappeared in an instant, leaving only the ugly to maintain the illusion rather bored.

However, inside this snow-capped, windswept mountain illusion, it is a different scene.

There are many military tents, and there are soldiers everywhere who are resting or cultivating.

But the most eye-catching thing is the crowd surrounded by three circles inside and three circles in front of the tent.

In the middle of the crowd, two warriors from the Xuangong Realm were fighting each other.

One is the deputy commander of the First Army, the seventh-fold cultivator of the Xuangong Realm, and the other is the fifth-fold warrior of the Xuangong Realm with a two-winged fire wolf phantom rising behind him.

This warrior with the two-winged fire wolf phantom rising behind his back was the demon spirit warrior who had just completed the fusion and refining.

This time, the more than 4,000 demon spirit soldiers of the Xuangong Realm that Ye Zhen exchanged were all fused with the Beast Blood Demon Spirit Pill refined by the Fire-winged Wolf Demon in the late stage of the Xuangong Realm.

The Fire-winged Wolf Demon is a social demon beast, which is most suitable for refining the Beast Blood Demon Spirit Pill of the Xuangong Realm.

At this moment, this demon spirit soldier looked as hideous as a wolf, and the whole person seemed to be instinctive, lying on the ground like a wolf, and with Ye Zhen's order, he immediately made a flame and pounced.

"Well, the short-range burst speed is comparable to that of a martial artist in the early stage of the Realm King Realm. ”

"The strength should exceed that of a martial artist of the same level by more than fifty percent!"

"The reaction is faster than before!"

"It seems to be more belligerent!"

......

A pair of freshly baked demon spirit soldiers kept stepping forward to practice with normal Xuangong Realm martial artists, while Ye Zhen kept making assessments on the side.

made a comprehensive assessment of the strength of the demon spirit soldiers, and the joy in his eyes became stronger and stronger.

The demon spirit soldiers fused with this transaction were even more powerful than Ye Zhen imagined.

Especially in close combat, the strength is comparable to that of a martial artist in the late stage of the Xuangong Realm, and this is still just fused into a demon spirit warrior, and he is not too familiar with strength and speed.

Once you master this power, you will become even stronger.

If it is paired with higher-grade standard armor, it can definitely become an elite army that invades like fire.

And another good news is that except for a few generals, all the soldiers have completed the refining and fusion.

In the space of a day and a half, these soldiers who had cultivated in the Mirage Dragon Ball had completed the transformation of demon spirit soldiers in a way that seemed fantastic to them.

The most amazing thing is that the success rate of refining and chemical fusion is as high as 99%.

Of the more than 4,200 beast blood demon spirit pills, less than forty failed to fuse and transform, and none of them died.

The dragon essence blood given by Ye Zhen is the most important reason.

However, the commander who can provide the dragon essence blood for the big head soldiers under his command, I am afraid that in this world, there is only Ye Zhen.

"From today onwards, this army, independently organized into a battalion, will be called ...... Wolf Battalion!"

Almost the moment Ye Zhen's voice landed, Niu Er quietly appeared beside Ye Zhen, and eagerly handed over a few pieces of jade slips, "Marshal, urgent military situation!"
