With a plug-in, I can kill through the dungeon world

"Okay." Mu Chengqian nodded slowly.

Immediately, Mu Rufeng left the Dali Palace directly.

When Mu Rufeng appeared again, he had already appeared at the entrance of the Netherworld, the territory of the demon dragon clan.

Below, there is an open space, and the ground is made of dark rocks, the material of which cannot be seen.

In the center of the open space, there is a huge crack.

It is hundreds of meters long and dozens of meters wide, and a large amount of negative energy is emerging from the crack.

There hasn't been much change here since he left.

No, the only thing is that the yin energy here seems to be more intense.

In other words, all the ghost energy in the entire third forbidden land has been transformed into yin energy.

The ghost energy in the underworld began to sublimate and transform into ghost energy. The third forbidden land, as a famous forbidden land in the entire underworld, was naturally the first batch.

When he met Mu Chengqian before, he also noticed that Mu Chengqian's strength seemed to be weakening.

I think it’s because the ghost energy turned into yin energy.

If Mu Rufeng had not come here, perhaps after a few years, Mu Chengqian's cultivation might have broken through to the level of a God.

There are a lot of strange books and monsters around.

The last time Mu Rufeng came, the human breath instantly woke them up. After some communication, he gave him a lot of powerful props and asked him to pass them on to his descendants.

But this time, when Mu Rufeng appeared, he did not leak any aura at all, so naturally he did not wake up these monsters.

Mu Rufeng went directly into the netherworld.

The yin energy in the underworld is even more dense, about ten times denser than that of the outside world.

The surroundings were not barren, but some black grass grew there.

These are soul herbs, which are relatively rare spiritual medicines.

After consumption, it can enhance the cultivation of the strange Yin energy. For practitioners, it can also be used as medicine to make pills, as if it is the main ingredient of a pill that enhances the soul.

If he had come before, Mu Rufeng would have pulled out all the plants without leaving a single one, but now, Mu Rufeng doesn't care much about them.

Mu Rufeng would not look down on even a thousand-year-old soul grass. But if it was a ten-thousand-year-old soul grass, Mu Rufeng would accept it with a smile.

After a slight sense, he flashed and appeared in front of Ao Zhi's huge corpse.

At this moment, Ao Zhi was lying on the ground without any movement, and looked as if he was really dead.

But Mu Rufeng could sense that Ao Zhi was actually practicing.

The next moment, Ao Zhi opened his bloody mouth, and with each breath, countless negative energy was sucked in, and then the foul air was exhaled.

Then Ao Zhi became silent again, breathing about once a minute.

“In terms of strength, he has become much stronger, and his cultivation has reached the late stage of the Divine Lord.” Mu Rufeng nodded slightly.

When Ao Zhi was reborn, he was only at the initial stage of the God Lord's cultivation. Later he was killed by the God Lord Wufo. After his death, he turned into a strange dragon and still had the cultivation level of the initial stage of the God Lord.

However, another consciousness was born in the dragon's corpse. With the help of Mu Rufeng, Ao Zhi devoured the strange dragon's consciousness and broke through to the middle stage of the Divine Lord.

Because the world has undergone tremendous changes, the ghost energy has transformed into Yin energy, and Ao Zhi's cultivation has directly broken through to the late stage of the Divine Lord.

Just as Mu Rufeng was sighing, Ao Zhi's huge dragon body slowly moved.

Then the huge dragon's eyes suddenly opened.

A violent momentum suddenly surged in all directions.

"Ah, Mu Rufeng, Mu Rufeng, you are here." A familiar voice sounded in Mu Rufeng's ears.

The next second, a faint light appeared on the dragon's body and then it quickly changed into the appearance of a woman.

Ao Zhi was wearing a black robe with a dragon pattern, a pair of black deer antlers on his forehead, and a mark between his eyebrows.

"Ao Zhi, long time no see." Mu Rufeng greeted with a smile.

"Hmph, you haven't come to see me for so long, I thought you had forgotten me." Ao Zhi snorted.

"How could I forget you? I'm here again." Mu Rufeng said with a faint smile.

"By the way, I feel like you seem to be different than before. I can't sense your cultivation level yet. Have you also broken through to the Divine Lord?"

"Now that you have broken through to the level of a God, can you make a contract with me and take me away from here?" Ao Zhi said excitedly.

She had stayed in Mu Rufeng's soul space before and followed Mu Rufeng around the outside world. The prosperity and novelty there really attracted her.

If she hadn't encountered the dragon body that had given birth to a new consciousness, she would definitely have stayed in Mu Rufeng's body forever.

Later, with the help of Mu Rufeng, he successfully devoured the consciousness of the strange dragon, took control of his own body, and was looking forward to leaving here.

"I'm not here to sign a contract with you this time." Mu Rufeng said slowly.

"Ah? If you don't want to sign a contract, then why did you come to me?" Ao Zhi's face suddenly darkened.

She was angry, so did he just come to see her?
"Although I won't sign a contract with you, I will still take you out." Mu Rufeng said with a smile.

"Mu Rufeng, after not seeing you for so long, you've learned to make jokes now, right?" Ao Zhi said angrily when she heard that.

Although Ao Zhi is tens of thousands of years old, Ao Zhi's main soul has long since died.

Ao Zhi is now just a remnant soul, and even a remnant soul that has lost all its memories.

Later, with the help of Mu Rufeng, he slowly repaired his remaining soul, and finally swallowed the strange dragon to regain his memory.

However, even though her memories returned, she did not regard those memories as herself, but as a new person.

So, judging from her personality, she has the mentality of a girl in her teens or twenties.

If it weren't for those memories, Ao Zhi would probably have the same mentality as a child now.

"But how are you going to take me out? Even with my current cultivation level of the middle stage of the Divine Lord, I cannot leave here." Ao Zhi said.

"Don't worry, my cultivation has improved a lot, and now I have control over the strange world." Mu Rufeng said with a faint smile.

"I eat beef without thinking, do you think I'm a fool?" Ao Zhi rolled his eyes at Mu Rufeng.

"By the way, please bring me some food first. I know you must have it. I've been craving for it for a long time. Anything will do." Ao Zhi said hurriedly.

"Hehe." Mu Rufeng didn't explain, let alone take out the things. He continued: "Ao Zhi, do you want to go out as you are now, or do you want me to help you rebuild your body and come back to life?"

"Huh? Come back to life? How? Can you let me reshape my body and turn into a real dragon?" Ao Zhi said with a sneer.

"Of course, as I said, my cultivation has improved a lot, and I can do this now."

“However, there is one thing that your cultivation may regress and you will need to practice again. Of course, not from the beginning. It will probably make your cultivation regress to the early stage of the Godly Lord.” Mu Rufeng said.

"Are you serious? What is your current cultivation level?" Ao Zhi saw that Mu Rufeng did not seem to be lying, and asked hurriedly.

"Daluo Immortal." Mu Rufeng said, releasing the aura in his body.

In an instant, Ao Zhi sensed the divine aura on Mu Rufeng.

"Daluo Immortal? You actually broke through to Daluo Immortal? How is this possible?" Ao Zhi was horrified.

Ao Zhi also knew about the realm of Daluo Immortal. After all, this was not rare information tens of thousands of years ago.

She thought Mu Rufeng's cultivation level was at most the level of a Divine Lord. How long had it been? How could he have directly become a Daluo Immortal?
"So, do you want to go out as a strange dragon or do you want me to reshape your body for you? Now the strange world has turned into the underworld. I created the underworld and control the entire underworld." Mu Rufeng said.

"I want to rebuild my body. I want to live. But, what is going on? Has something big changed outside?"

"Starting from the past few months, I have felt that there have been great changes here. All the ghost energy has turned into yin energy." Ao Zhi chose to reshape his body and at the same time asked Mu Rufeng about what was happening outside.

"Well, I used the Chinese world to swallow up multiple worlds and merge them. The strange world is one of them. Now, the strange world and a small underworld have become the underworld of the Chinese world."

"The Chinese world is the world of the living. Now the world is still continuing to merge, the territory of the continent is still expanding, and the upper limit of the world is also constantly increasing." Mu Rufeng explained.

"So, so many things happened outside. Come on, help me reshape my body. I want to go to the outside world." Ao Zhi said immediately.

"Yeah." Mu Rufeng nodded slightly.

Then Mu Rufeng put his hand on Ao Zhi's head.

In an instant, divine light bloomed around Ao Zhi.

Soon, waves of sound were heard all around.

Then, a big river appeared faintly in the sky.

The surrounding space was instantly frozen, and Mu Rufeng casually summoned the river of time.

As long as Xuanzun does not come out, Daluo Immortal will be standing at the pinnacle of all heavens and worlds.

Mu Rufeng can directly reshape Ao Zhi's body, but Ao Zhi's cultivation will become nothingness, and he will have to start practicing from scratch as a dragon.

However, Mu Rufeng chose to reverse time and space, directly returning Ao Zhi's body to her state tens of thousands of years ago.

In this way, Ao Zhi's body directly became that of a real dragon, but his cultivation was only at the initial stage of the Divine Lord.

Soon, the mysterious power of time and space was seen flowing through Ao Zhi's body, and the next moment, Ao Zhi's body began to undergo amazing changes.

Time is going backwards, and there is only Ao Zhi's body.

However, there is another force that protects Ao Zhi's current soul, preventing it from being affected by the power of time and space.

Ao Zhi's breath began to weaken, and the strange flesh and blood that had grown back began to collapse, and finally turned into dry bones.

Time passed minute by minute, and every second, it seemed that dozens or even hundreds of years had passed for Ao Zhi.

In just a few minutes, Ao Zhi's dry bones began to become shiny and alive, and then flesh and blood began to grow rapidly.

Finally, a real dragon body appeared in front of Mu Rufeng.

"That's almost it." Mu Rufeng loosened his arms and withdrew his own strength.

The looming river of time in the sky disappeared in an instant, and the stagnant space around it recovered.

Ao Zhi slowly opened her eyes, raised her hand and looked at her delicate little hand.

"I-I'm alive." Ao Zhi couldn't believe it and quickly began to touch her cheeks with her hands.

Then she felt something was not right and immediately sensed her body. She jumped up on the spot with excitement, like a naughty little girl.

"Mu Rufeng, Mu Rufeng, I'm alive. Look, touch my warm flesh." Ao Zhi came forward, grabbed Mu Rufeng's arm and moved his hand towards her own face.

Mu Rufeng only felt a warm, soft and delicate feeling on his hands.

"Hehe, just touch it yourself. If I don't touch it, I will be overstepping the boundaries." Mu Rufeng coughed twice and immediately pulled his hand back.

"Great, great, I'm alive. I'm finally not that rotten, smelly corpse anymore." Ao Zhi didn't care at all and was still excited.

"Okay, come on, I'll take you to a place and I'll make you even happier later." Mu Rufeng said.

"Hmm? Even happier? Are you going to take me out? Take me to the outside world to eat delicious food?" Ao Zhi immediately looked at Mu Rufeng with anticipation.

"Well, that's not the case. It will definitely make me happier than going out into the world to eat delicious food." Mu Rufeng replied after a pause.

"No? Then where are you taking me?" Ao Zhi was a little confused. Is there anything more joyful than going out into the world and eating delicious food?
"You'll know when you get there." Mu Rufeng smiled slightly, and then with a wave of his hand, he took Ao Zhi and tore through space and disappeared on the spot.

……

There was a huge snowstorm blowing across the endless snowfield.

However, in such a huge snowstorm, there was a canyon where not a single bit of wind or snow could blow in.

The density of Yin energy in this canyon is more than ten times higher than that outside.

On both sides, there are densely packed old Netherworld flowers, each of which is at least a thousand years old.

And in the depths of the canyon, there is a cold spring emitting white mist.

Just at this moment, a space crack emerged, and Mu Rufeng and Ao Zhi walked out of the space crack.

"It's so cold here, what are we doing here?" As soon as Ao Zhi came out, she felt the coldness all around her and instantly mobilized her own immortal power to dispel the cold.

"You'll know in a moment." Mu Rufeng smiled, and then released his breath slightly.

"Hey, those over there seem to be Netherworld Flowers. I didn't expect that Netherworld Flowers would grow here." Ao Zhi also discovered those densely packed Netherworld Flowers at this time.

Just at this moment, the cold spring suddenly moved, which instantly attracted Ao Zhi's attention.

For some reason, she suddenly felt a familiar breath, but even though it was very familiar, she just couldn't remember whose breath it was.

At this moment, the cold spring was constantly surging, and a large number of cold spirit fish kept jumping out of the cold spring, as if they were in panic. (End of this chapter)
