Outside the underground mansion, Yue Ling saw that the whole ghost mansion was shaking and seemed to collapse.

But not after all.

This ghost house is not simple. It contains space.

At this time, the ghost house shook, indicating that there was still fighting inside.

those closely involved cannot see clearly,

Yue Ling is here, but she can't see the war in the ghost house.

On the contrary, those who live in the city of death can see all this.

In the ghost house, the battle between Ning Chen and the purple robed ghost king is extremely fierce.

However, Ning Chen was very relaxed and everything was under his control.

"Die!"

Ning Chen finally killed the purple robed ghost king.

It turned into a purple light and condensed into a door.

At this time, Ning Chen let Yue Ling in.

"Does this door lead to hell?"

Ning Chen's secret way in his heart.

What is it? Ning Chen didn't think much, but continued to move forward.

When you arrive, you will naturally know what the situation is.

Through the purple gate, Ning Chen found that he did not come to hell, but came to a new ghost house.

"What's going on?"

Ning Chen's face changed slightly.

This is a little different from what you think.

I thought that if I killed the ghost king in three states, I could pass through the hell.

But now it seems that he thought too simply.

In the new ghost house, there is a blood color. Two head lanterns are hung on both sides of the gate. This picture is very frightening.

Ning Chen was not affected at all.

However, this situation is indeed somewhat surprising.

Ning Chen did not hesitate and continued to walk into this new ghost house.

"How dare you come here from the shallow world?"

"In the middle-level underground world, no one has been here for a long time. If you can come, it shows that you have great potential. Only when you eat, can you have a price."

At this time, a ghost King appeared in front of Ning Chen.

The ghost king in red is more than a hundred times larger than before.

In the face of such a situation, Ning Chen frowned.

Yue Ling seemed to think of something. Her face was pale and said, "it is said that the underground world is divided into the shallow world and the deep world. Once activated, the difficulty will increase ten times. However, it is said that there is a source heart in the deepest part of the underground world."

"Once swallowed, it can impact an amazing realm."

"Moreover, even if you are on the verge of death and suffer multiple injuries, even if you are injured by the road, you have become a disabled person. A source heart can change everything, so that people can not only return to the peak, but also break through directly."

"The source heart is not available. Unexpectedly, this rumor may be true, but now we are only in the middle-level underground world."

As soon as Yue Ling's words fell, the voice of the ghost king came and said, "little girl, I didn't think you could understand these."

"Then I can tell you the truth. If you want to enter the deep underground world, you must defeat me."

"It's just that this possibility doesn't exist at all."

The ghost king in the middle underground is too arrogant and confident.

However, Ning Chen agreed with him and said, "since there is a deep underground world, we can kill it!"

After that, Ning Chen fought with the ghost king of the middle-level underground world.

This ghost king is really powerful, but Ning Chen's strength is unimaginable.

Ning Chen always felt that he had returned to the peak.

But he found that his strength was still improving without a breakthrough.

After this time, Ning Chen felt that he had broken a certain limit again.

Ning Chen released his strength and fought endlessly with the ghost king of the middle ghost house world.

Gradually, the arrogant and confident ghost king of the middle world was suppressed by Ning Chen. No matter how it struggled, it failed.

It had a premonition that it was going to die.

"I admit defeat and let you pass."

"Don't kill me. Once you kill me, you will enter the deep underground world. There is no doubt that you will die at that time, because the deep-seated ghost king is not what you can imagine."

In order to survive, the ghost kings of the middle world all admit defeat and appear extremely humble.

"My goal is the heart of the source. How can I enter the deep world without killing you?"

Ning Chen said faintly.

Finally, he killed the ghost king of the middle world.

Form a door to the deep world.

Ning Chen went in without hesitation.

This is a bloody world, with blood mist everywhere.

On the ground, there are countless blood grooves. The blood water on them is flowing to one place, where there is a bloody heart.

The heart of the source.

There is no doubt that that is the heart of the source.

However, in front of the heart of the source, there is a figure blocking Ning Chen.

The ghost king of the deep underground world.

That's it.

Kill it and you'll get the heart of the source.

Ning Chen is absolutely determined to get the heart of the source.

Because if the active mind, he can break into a higher realm when he breaks into the condensed Tao realm.

Only when you improve yourself can your safety be guaranteed. At least you can enter a higher-level area.

"The deep underground world, since it exists, few people can come in. Even if they can come in, they will eventually be eaten by me."

"The last person, I still remember a million years ago. Unexpectedly, there are still people who can break in today. However, the fate of your mole ant is already doomed, because I will swallow you eventually."

The ghost king of the deep underground world has the same body as ordinary people.

However, his breath is really powerful and terrible.

Ning Chen must use his real skills at this moment. Otherwise, it will be difficult to clean up the other party or even swallowed by the other party.

Therefore, Ning Chen did not dare to be careless.

But he will not shrink back, but take the initiative to kill the past.

"This time, I will end you."

Ning Chen is also very direct, strong shot.

The ghost king of the deep underground world also shot.

"Ghost tie!"

It whispered.

Ning Chen suddenly saw that the blood ditch and blood water around turned into blood cords, and then interwoven into a net to cover Ning Chen.

"Sword meaning, sharp!"

Ning Chen seems very calm.

The sword is extremely sharp. Now cut forward.

All the blood cords in the front were disconnected, and Ning Chen could not be bound at all.

In an instant, Ning Chen killed the ghost king of the deep underground world.

All this shocked the ghost king of the deep underground world.

Boom!

However, it also responds quickly.

A blood shield was formed in front of him in an instant.

Ning Chen chopped the blood shield with a sword, but his blow was also resisted.

"Unexpected."

"What a surprise."

"You can have such strength, so I can have a good fight."

"I haven't really moved my muscles and bones for too long. As long as you can satisfy me, I will let you choose a more comfortable way to die."

There are some happy tunnels in the deep underground world.

Ning Chen has no nonsense and only responds with a strong attack.

At the beginning, the ghost King's attitude of the deep underground world was still very light. Gradually, its look began to become dignified.
