The fourth floor.

When Su Yu stepped into the fourth floor, he felt a special feeling.

The five internal organs are like ovens!

The internal organs are burning!

Su Yu took a deep breath. He felt a kind of power of the five elements at this level. He practiced a path and often said that the five internal organs were about the five elements. Su Yu instantly realized that this level might be where the five internal organs were!

In other words, the four, five, six and three layers may be in the entire abdominal cavity, the areas where the five internal organs are distributed, including the area where the navel is located.

"Where are those arms?"

Su Yu thought to himself that he didn't seem to see his hands. If someone really put them on the ground, his arms might be hanging down. Could it be that they are also on the underground level?

Have you inserted your arms into the undead world?

There is still a possibility.

Not to mention anything else, the concentration of vitality is beyond imagination!

"The lungs and heart are all in this area, right?"

Su Yu muttered in his heart, heart... this is still very important to any cultivator. Even if Su Yu really explodes his heart and is unable to regenerate his flesh and blood, then he will die... his body will die.

At that time, his only way was to preserve the sea of ​​will and rebuild his body.

However, if the heart has not been completely destroyed, whether it is reborn with blood or reborn with flesh and blood, you can reorganize the body, but it is a little weaker, but the physical body level is still there and you don’t need to start from scratch.

"If the heart is on this level... I have to go and look for it!"

Su Yu thought to himself, and looked at the passage below, his eyes were changing, and the river map was sweeping layer by layer. This time, it was really a disaster!

At least I am not considered a scattered grass, but the river map is better, so I really don’t leave any one.

Now, I'm afraid many people have died.

Thousands, there are definitely some.

"This is a tragic term!"

Su Yu shook his head, I can't blame me for this, at least, the human race cannot blame itself. If the human race dies, it has nothing to do with Su Yu.

He killed so many thousands of races, and in theory, human races can have some advantages.

Unfortunately, this guy from Hetu killed indiscriminately and rushed up one by one... If this continues, the weak will soon join forces, otherwise the higher-level people will not be able to go up.

The higher the number of layers, the more dangerous it is. In the fourth layer, Su Yu had already felt a flame burning in his five internal organs.

The weak will probably not stay for long and will be burned to death.

"Wu Lan and others are very weak..."

Su Yu frowned slightly. These people were just flying in the air. It would be fine if they stayed on the lower third floor. Even if they were just staying here, it would be a torture.

"I don't know how many people there are on the fourth floor and whether there is a Sun and Moon Realm."

When you reach this level, there may be some powerful Sun and Moons.

Those who are not too old and those who are not too strong are probably on the fourth floor, including Liu Wenyan and others.

Of course, three days have passed, and this is the fourth day. They may have left the fourth floor and advanced to a higher floor.

...

Just as Su Yu arrived at the fourth floor.

On the fourth floor, there is a treasure land that is very special.

You can actually see the entire fourth floor. You can see two huge mountains standing on both sides of the fourth floor. There is a V-shaped canyon between these two mountains. If you look at it backwards, Su Yu can probably tell that it is the pipe connecting the lungs.

However, here, an extremely huge canyon was formed.

There are people on the two giant mountains at this moment.

The lungs are responsible for breathing.

It has the effect of exhaling and absorbing the essence.

The fourth level of struggle is less, because the fourth level is very suitable for some people to practice. Cultivate on the tops of two high mountains to strengthen the qi and blood, strengthen the body, and the efficiency of exhaling and absorbing the essence is hundreds or even thousands of times that of the outside world!

On the fourth level, the internal organs are burned, but as long as you persist and practice on the mountain, you will soon feel a sense of coolness, resolving this crisis.

The fourth floor is also an area where many people strengthen themselves.

On the fourth floor, almost all the strong men under the sun and the moon gathered. The first three floors are almost done. Now, almost all the living sun and the moon gathered on the fourth floor.

There are many people spreading on both sides of the mountains.

There are about 2,200 people in the entire Xingyu Mansion, and the number of people gathered on the fourth floor is close to 1,500.

Even the human race has about 300 people on this level.

Xia Huyou and his team entered the fourth floor with a group of people, and quickly joined the other human races, occupying the mountains to the east, with almost 300 human races, which were probably all living people under the sun and moon of the human race.

Including some guys who left early, some are still on the third floor... dead!

A few people have been on the fourth floor and are now excluded by many people.

...

On the eastern mountains, the human race gathered together. Everyone was practicing. While practicing, they listened to Xia Huyou and the others talking about the experiences of the lower third level.

Many people's faces changed.

The undead is here!

The invincible undead!

The strongest person here is not someone else, but Zhu Tiandao's son Zhu Guangshen, who is Zhu Hongwen's father and Zhu Hongliang's uncle.

He stepped into the sun and the moon, but it was just a first level and had been here forever and had not been up.

At this moment, when hearing Xia Huyou and the others' stories, Zhu Guangshen frowned slightly and said, "Nephew Huyou, do you say that the dead spirit used a book to kill hundreds of people, and the book carries the sacred power?"

"right!"

Xia Huyou nodded and thought in his heart, could this person know it was Su Yu?

Books are rare.

Of course, it is not uncommon, some are still there.

As for Su Yu's book, everyone also saw some projections during the last forging, but it was very illusory. No one knew what it looked like, let alone Su Yu just forged the ground soldiers last time.

But the book you see is at least at the level of a heavenly soldier, and is extremely powerful.

Zhu Guangshen said again: "That undead can speak, saying that he is the pioneer under Hetu?"

"right!"

"River map..."

Zhu Guangshen murmured, someone didn't understand and asked, "Your Highness, who is Hetu?"

"Who is Hetu?"

Zhu Guangshen thought about it and said, "I don't really know who the Hetu is. Didn't Su Yu mention it when he allocated the quota last time? He said he was forced to learn from the Hetu... After that, the human race did some understanding."

Zhu Guangshen thought for a while and hesitated: "Some things were told by my uncle to me..."

As soon as these words came out, everyone suddenly pricked their ears!

If you have a good knowledge, there is definitely Zhu Tianfang, the world of heaven and all races. He is the Minister of the Huang department who has the information. There is probably no news that can be hidden from him.

"Hetu, the human race's strong man who changed the first tide!"

Zhu Guangshen explained: "Before us, after ancient times, there were actually nine tide changes! The so-called tide changes are the battlefield of the heavens, the war broke out, the war of all worlds, each war ended, the battlefield of the heavens was closed, this was a tide change!"

"Once, counting the opening and closing time, lasting about ten thousand years!"

"So, strictly counting, the River Tu is a person from almost 100,000 years ago. It can leave some legends countless years later, and it is also the pride of that era!"

"Hetu, in ancient times, the descendant of a peerless powerful man was born after the destruction of ancient times."

"The first tide change began, and the River Map made a name for itself on the battlefield of the heavens...it can be compared to Su Yu..."

He looked at everyone and smiled bitterly, "Don't say, Hetu is very similar to Su Yu! He is also a talented monster like Su Yu, who has made rapid progress. In a short period of time, he entered the invincible realm... But he can cause trouble just like Su Yu. Not long after, he was attacked by a half-emperor-level strongman... In desperation, he had just proved invincible, and had to choose to become the lord of the Hongmeng Ancient City and save his life."

"This path... is really similar to Su Yu!"

When everyone else nodded after hearing what he said, they were all a little surprised, they really looked like it.

Zhu Guang took a deep breath and said, "After that, the River Map was dormant for a while. In the middle of the first tide change, the battle between all races actually had forgotten the River Map because he was restricted to the ancient city."

"However, Hetu is unwilling to be a supporting role in that era, and is unwilling to spend the rest of his life in the ancient city... So, in the middle and late stages of the first tide change, he came out again, and swept across the heavens and the worlds with his army of necromancers, and a war that lasted for hundreds of years broke out..."

"Until the end, the undead lost control, Hongmeng guard closed the undead passage, cut off the source of the dead energy, cut off their retreat, and took action to kill the Hetu, which ended the first tide battle."

When he said this, Xia Huyou couldn't help but say, "How could he bring the dead spirits outside? Also, aren't there any rules in the ancient city? Why didn't you stop it at the beginning, but then you took action to stop it?"

"I don't know this."

Zhu Guangshen shook his head, "It's too long, even the Lietian Pavilion has no more records. After that, I heard that the Hetu has always existed in the undead passage in the ancient city of Hongmeng. He has taken the fruit of life and death, retained some memories, and has been unwilling to fail... These are all records of the Lietian Pavilion. Countless years have passed, and he has actually come out again."
To be continued...
