The bloody stones, bloody grass, bloody ground, bloody sky, and even the green grass were covered with a layer of blood. Everything in the Demon Soul Battlefield was exactly the same as when Ye Zhen first came in five years ago.

However, soon Ye Zhen discovered the change!

That is the Demon Soul Soldier, the Demon Soul Legion!

Five years ago, Ye Zhen had just entered the Demon Soul Battlefield and encountered Demon Soul soldiers. Not long after, he could discover various demon soul legions of different sizes.

But now, Ye Zhen has been in the Demon Soul Battlefield for half an hour and has flew for more than a thousand miles. Not to mention the Demon Soul Legion, he has not even seen a Demon Soul Soldier.

Five years ago, there were demon soul soldiers in the Demon Soul battlefield, but now it is more like a dead domain!

Apart from the two living creatures Ye Zhen and Yunyi Tiger King Kitten, there is no trace of life breath.

"These changes may be caused by the failure of the Battle Soul Blood Flag to return..."

This is the only reasonable guess that Ye Zhen can make. Ye Zhen also wants to hunt the Demon Soul Legion to obtain Demon Soul Blood Crystal to supplement the consumption of the Battle Soul Blood Flag. Now it seems that this idea has failed.

After wandering around the Demon Soul Battlefield for more than an hour, without any discovery, Ye Zhen went straight to the center of the Demon Soul Battlefield - the Demon Soul Palace.

The Demon Soul Hall is as majestic as ever, simple and majestic as ever. The gates of the Eight Demon Soul Hall are distributed in all directions and look extremely bulky.

Ye Zhen was a little curious. How did such a bulky thing become a so-called war fortress?

The gate of the Demon Soul Palace is still closed. Under normal circumstances, it takes 10,000 demon soul blood crystals to open the gate of the Demon Soul Palace. The Demon Soul Blood Crystal is a guarantee of the passage in the Demon Soul Palace.

Now, Ye Zhen does not have the Demon Soul Blood Crystal, but has the Battle Soul Blood Flag.

According to the information in the original imprint in the Battle Soul Blood Flag, the Battle Soul Blood Flag is the control center of the Demon Soul Hall. As long as the Battle Soul Blood Flag can be completely recognized, entering and leaving the Demon Soul Hall is like entering a nobody's realm.

The next moment, the battle soul blood flag flew out from Ye Zhen's arms, and a blood light flew out. The door of the Demon Soul Palace squeaked and dumbly, allowing Ye Zhen to step in slowly.

A brilliant blood-colored passage leads straight to the distance, as if endless, and there are blood-colored starry skyscrapers on both sides of the passage, like a dream.

According to previous experience, as long as the warrior moves along this blood-colored channel and steps out left and right at will, he will enter a room and start to encounter the great fortune.

In fact, according to the information in the origin of the Battle Soul Blood Flag, this dazzling blood-colored channel is actually an extremely powerful illusion array. Once it is fully activated, let alone the strong man in the Buzi Realm, even the king in the Kaifu Realm will be affected by this blood-colored starry sky illusion array.

Because there is no one to control the Demon Soul Palace, the blood-colored starry sky illusion array is waiting to be launched. Otherwise, if there were so many spiritual-guiding warriors in the Black Dragon Realm who could fill in the Demon Soul Palace, I am afraid that I would not be able to explore the Demon Soul Palace.

Turn left casually, Ye Zhen stepped towards the blood-colored starry sky, and his body disappeared into this blood-colored channel.

A single door three meters high and two meters wide appeared again in front of Ye Zhen. There was a blood crystal groove on the left side of the door, which was where the room was opened to place the demon soul blood crystal.

As the battle soul blood flag floating in front of Ye Zhen shot out a blood light, the door automatically opened in front of Ye Zhen, and Ye Zhen stepped in again.

There was still nothing to see in the single room on the first floor. However, there was a teleportation channel in this room, but Ye Zhen did not step into the teleportation channel, but walked straight towards another single door. Blood light flew out, the door opened, and Ye Zhen entered again to explore.

After searching in the next room, blood flashed on the Battle Soul Blood Flag, and Ye Zhen stepped into another room again.

"One hour!"

"I only have one time, otherwise all my previous efforts will be wasted, or in other words, I will start to encounter endless luck..." With a wry smile, Ye Zhen accelerated his pace.

There is actually a reason for Ye Zhen to search for one room at a time.

It’s not that Ye Zhen wants to sweep away the treasures that may exist in the Demon Soul Hall. In fact, during the Five Kingdoms Conference, the treasures that may be found in the Demon Soul Hall have always been rewards given to explorers by major empires, and the sects do not ask for them.

The treasures, secrets, and martial arts found in each room in the Demon Soul Hall are actually suitable for warriors in the Spirit-Induction Realm or the Spirit-Incarnation Realm. Once their cultivation level breaks through to the Spirit-Incarnation Realm, the treasures in each room here are basically useless.

The main goal of all countries is the battle soul blood flag.

Having said that, if Ye Zhen wants to sweep away the treasures in the Demon Soul Hall, it is very simple - when Ye Zhen completely controls the Demon Soul Hall through the Battle Soul Blood Flag, Ye Zhen wants to get the remaining treasures in the Demon Soul Hall, it is just an idea.

The real reason for Ye Zhen’s exploration of this room by room is to find the Cardinal Hall!

The Demon Soul Hall is a mobile fortress of the ancient demon army. The place where senior generals handle military aircraft, the most important place is the ninth floor of the General Hall, which is the place where the generals discuss matters. The Battle Soul Blood Flag is hung there most of the time.

But in addition to the Hall of Constitutional Affairs, there is another extremely important point, that is, the Hall of Cardinal that Ye Zhen was looking for at this time.

In terms of importance, the Cardinal Hall is several levels more important than the Secretary-General Hall.

Because the Cardinal Hall is the center that controls the entire Demon Soul Hall, as long as you hold the Battle Soul Blood Flag and brand the soul mark in the Cardinal Hall, you can control the Cardinal Hall.

On the contrary, if the Cardinal Hall is destroyed, the entire Demon Soul Hall will be paralyzed and become a waste.

As the top priority of the Demon Soul Hall, the Cardinal Hall not only has the most powerful formation protection in the Demon Soul Hall, but also another secret defense method - it is the movement direction.

Every hour passed, the Cardinal Hall would automatically change its direction under the operation of the formation, and the conversion range was any position in the more than one thousand rooms on the ninth floor of the Demon Soul Hall.

Maybe in the middle of the first floor, maybe in the ninth floor, maybe in the fifth floor...

In this case, if the enemy gets information from the Demon Soul Hall, even if he barely breaks in, it will be outdated.

As long as the Cardinal Hall is not lost, you can deal with it calmly.

What Ye Zhen needs to do now is to find the Cardinal Hall within one hour, otherwise, after one hour, the Cardinal Hall will be changed to let Ye Zhen search again.

The only thing Ye Zhen could do was to use a stupid method to quickly search one by one.

Fortunately, the War Soul Blood Flag opened the door. If it was opened with the Demon Soul Blood Crystal, even Ye Zhen would not be enough to massacre a large army of 100,000 people.

If Ye Zhen continues to search for one room after another, he can occasionally gain something.

Low-grade treasure armor, low-grade martial arts and skills. I found several books, but I never found the medium-grade treasure armor like the Black Wind Treasure Armor.

Even though Ye Zhen used a stupid method, things did not go as smoothly as Ye Zhen imagined.

In a blink of an eye, one hour, two hours, three hours, five hours passed. Ye Zhen found the ninth floor of the Demon Soul Hall from the first floor, and still couldn't find the Cardinal Hall.

Even Ye Zhen marked every room he had searched for, but it was still useless.

Soon Ye Zhen found the reason!

Interconnection!

Many rooms in the Demon Soul Hall are actually interconnected. Some rooms have two doors and even more than three rooms, and the next connected room is still the same.

The entire Demon Soul Hall is like a large maze. Every time Ye Zhen searches, he can find unmarked rooms.

There are two rooms with door passages, at least 500, and three rooms with channels, and more than 200. If this is the case, there will be tens of millions of changes in this room, so Ye Zhen can't think of searching them one by one.

Fortunately, the total number of rooms is only more than 1,600. If there are four or five thousand rooms in this room, Ye Zhen would really be dizzy.

After finding out the reason, there was no good solution. Ye Zhen could only use the stupidest method - to hit the fortune!

Searching in these more than a thousand rooms over and over again, try your luck!

Stupid methods sometimes have their own reasons for stupid methods. After a long time, as Ye Zhen stepped into an ordinary door, he suddenly turned around, as if he had entered an extraterrestrial starry sky.

In the room, there are blood-colored light everywhere, and under the blood-colored light are inscribed strange patterns, complex and abnormal array bases, array operation routes, and ring-shaped arrays. If you look closely, the array route can make Ye Zhen dizzy.

At this time, only blood light was flowing slowly in some of the formation routes, and it was obvious that only part of the formation was activated.

However, the most eye-catching thing is the blood-colored crystal platform in the middle of the starry sky formation line. The mysterious blood light flashed from time to time from time to time.

If you observe carefully, you will find that the final end points of all lines in this starry sky formation, or the opening points of all formation lines, are concentrated on this blood-colored crystal platform.

This blood-colored crystal platform is the control center of this Demon Soul Hall.

According to the information in the origin branding of the Battle Soul Blood Flag, as long as the soul brand is left in, you can control the entire Demon Soul Hall, the war fortress.

Walking forward, Ye Zhen followed the method left in the origin of the Battle Soul Blood Flag, and with a divine thought, a blood light shot out from the Battle Soul Blood Flag, suddenly covering the blood-colored crystal platform.

The blood-colored crystal platform, which was previously like a dead object, seemed to be alive in the moment when it was covered by the blood light of the Battle Soul Blood Flag.

The majestic soul wave suddenly rose from Ye Zhen's body, and an invisible and intangible soul imprint suddenly flew towards the blood-colored crystal platform and fell into it in an instant!

Buzz!

Ye Zhen only felt his soul tremble slightly, and an extremely strange feeling suddenly appeared in his heart.

As my mind moved, the distribution map of the 1,608 rooms in the entire Demon Soul Palace, and the situation in each room all appeared in Ye Zhen's mind. The function of every channel and every formation appeared in Ye Zhen's mind.

"It's so easy to mark it successfully..." Ye Zhen was a little surprised.

But just as Ye Zhen was secretly happy, a sudden change occurred.

The entire blood-colored crystal platform was filled with blood, and all the blood-colored light rushed towards the blood-colored crystal platform in an instant. Almost at the same time, on the demon soul battlefield outside the Demon Soul Hall, blood-colored lights also rose from all directions in the Demon Soul battlefield and rushed towards the Demon Soul Hall independently.

In an instant, the sea-like blood-colored light gathered around the Demon Soul Hall!

Wow!

An extremely terrifying blood-colored vortex suddenly formed and increased rapidly!

Ye Zhen was also stunned in the Cardinal Hall!

Because Ye Zhen knew everything inside and outside the Demon Soul Hall through the Blood-colored Crystal Platform!
