"Hong Huang, it's really difficult now!" The Netherworld Demon Lord shook his head, then looked at Lu Zheng, and said, "You are coming to me this time, it must not be a whim, where I am, only those old guys know, tell me, what is the matter with you coming to me." ”

Lu Zheng felt a little embarrassed, the Netherworld Demon Lord was here to guard the Ghost Spirit State, if he just called him away like this, not to mention whether he would agree or not, first of all, in a sense, this practice is very selfish.

However, Wen Qian was really worried, and after thinking about it, Lu Zheng still told the truth and told the Netherworld Demon Lord the ins and outs of the matter, and then said: "I know that the matter here is very urgent, so how to choose, I completely follow your opinion, if I can't leave here, I can also go to find Shi Zheng and the others." ”

The Nether Demon Lord laughed, stood up and patted Lu Zheng on the shoulder, and spoke: " If it was before you came here, I really couldn't leave here, not because I didn't want to leave, but because I was eroded by the power of darkness, and there was no way to leave, but now, you have solved the physical problem for me, of course I can leave here at any time, but before leaving, I also hope that with the help of your eighteen purgatory, the dark aura here can be completely devoured, although it is impossible to block the entrance, but at least in the last few hundred years, so that it can not be in danger of erupting. ”

Lu Zheng nodded: "I am willing to serve this." ”

"You are really good, at the beginning, we had a few ideas to build the Eighteen Purgatory, but in the end because it was too difficult, we had to give up, I didn't expect you to succeed, and you have evolved to this point, I really want to know what kind of scene it will be when your Eighteen Purgatory evolves to the peak. The Nether Demon Lord said with a smile, his eyes full of hope, as if he was a teacher who saw the joy of his disciple's success.

"I also fought crookedly, and only condensed the Eighteen Purgatory by accident, in fact, if there were no various materials such as the Eighteen Purgatory Ancient Tower, I would not have been able to let the Eighteen Purgatory appear. Lu Zheng said truthfully that the construction process of the Eighteen Purgatory, which is really complicated and unrepeatable, that is to say, it is absolutely impossible for Lu Zheng to recast an Eighteen Purgatory now.

This situation is very peculiar, because throughout the ages, no matter what kind of magic weapon it is, there are always many imitations, even if it is the treasure of the Immortal Emperor, there are countless people who imitate it, but when it comes to the Eighteen Purgatory, this point seems to be a little unworkable, because the structure of the Eighteen Purgatory is too precise, too complex, and interlocking, and there can be no mistakes.

The Eighteen Purgatory, which seems to be just a patchwork of components from several worlds, is actually composed of countless runes, and even a mistake in one rune may lead to the loss of all the previous efforts, and the entire Eighteen Purgatory will be completely scrapped.

"You can condense the Eighteen Purgatory, it is already very powerful, it proves that your luck is far stronger than a few of us old guys, perhaps, when you fight against the Netherworld in the future, you will also need to take action, and your Eighteen Purgatory will be together with several other magic weapons to guard the desolate land!" The Netherworld Demon Lord laughed, then looked into the distance, and said: "We can go, from here to Tongguan, although it is not too far, but it will take at least two or three days, so it is better to leave early." ”

"Two or three days......" Lu Zheng was stunned, according to his thoughts, even if the Netherworld Demon Lord has now been promoted to the realm of the Immortal King, if he wants to go from the Ghost Spirit State to Tongguan, it will take at least three or four years, but now it only takes two or three days to reach the Netherworld Demon Lord's mouth!

The Nether Demon Lord laughed: "Do you think that I am just an ordinary immortal king? I have also embarked on the path of a saint, if the holy fetus reaches the Nine Heavens, my own cultivation has become the realm of the immortal king, if it were not for the fact that there are still many things that have not been solved, I would have been in retreat and ready to break through to the realm of the immortal emperor, the distance from here to Tongguan may seem far to you, for me it is just a thought, just because I want to take you over, so it is troublesome and will be a waste of time." ”

Hearing the Netherworld Demon Lord's explanation, Lu Zheng finally understood, the Netherworld Demon Lord was a supreme powerhouse in the Saint Realm, how could it be comparable to an ordinary Immortal King? A monk in the Immortal King Realm, even if there were a hundred, was not an opponent of a Saint.

Moreover, what we are talking about here is still that kind of ordinary saint, not a saint like the Nether Demon Lord, a powerhouse of the Nine Heavens!

"Let's go. The Netherworld Demon Lord didn't say much, as soon as his figure moved, a golden light appeared in front of him, he grabbed Lu Zheng, the golden light flickered, and it disappeared in an instant.

Lu Zheng only felt that the infinite space around him was condensed, as if the original road of 500,000 miles was directly compressed into fifty centimeters at the moment, so naturally he could easily step over it.

"This is the great magic power of shrinking the ground into a ruler, and the real shrinking of the ground into a ruler, but the Immortal Emperor Law, which is circulated in the outside world, is all incomplete, and there is no way to compare it with the complete law. The Netherworld Demon Lord sent a message to Lu Zheng, which was the cultivation method of shrinking the ground into a ruler: "I know that you have cultivated a kind of two-winged supernatural power, if you cooperate with the shrinking of the ground into a ruler, the speed should be faster, I can't always be by your side, this is also equivalent to giving you some necessary means to defend yourself." ”

Lu Zheng felt the changes in shrinking the ground into a ruler, and understood that this was indeed the Immortal Emperor Method, because it was really mysterious, without hundreds of years of practice, it was difficult to understand the various changes in it, because it not only involved space, but also time.

It is equivalent to the moment you take your step, the surrounding time falls into a standstill, and it is precisely because of this that you can shrink the ground into a ruler and travel faster than the speed of light.

At the beginning, a man named Albert Einstein on Earth said that when the speed reaches or even exceeds the speed of light, it is possible to travel back in time and space.

However, Lu Zheng now wants to tell him that no matter how fast the speed is, even if it is thousands of times, tens of thousands of times the speed of light, the most that can be done is the relative stop of time, not traveling through time and space.

In other words, when the speed surpasses the past, the time about yourself and the time around you will enter a state of near stopping, since there is no time passing, then the effect of speed on time is naturally zero.

Of course, it is not impossible to travel through time and space, but it is not in this way, some great powers can directly rely on their own cultivation and their own understanding of time to successfully travel through time and space and return to the past.

However, even so, they will not easily change some things in the past, similar to the kind of direct shuttle back and kill the enemy in the weak period, it is simply nonsense, and few people will do this, because they will be burdened with great cause and effect, and the greatest possibility is that both sides will fall together.

The speed of the saint is really incomparable, especially after the 'unity of spirit and flesh', the Netherworld Demon Lord has reached a terrifying level, although on the surface, he is just an ordinary immortal king, but in fact, whether it is the physical body, the supernatural powers, or the mastery of the laws, etc., he is too much more than the ordinary immortal king, not a level at all.

In less than two days, the Netherworld Demon Lord had already descended into Tongguan, and took Lu Zheng to the center of Tongguan in an instant, and the breath of his whole body emanated, making the entire galaxy tremble, at this moment, the entire Tongguan knew that there was a great big man coming!

"Saint, this is the breath of a saint, and only a saint can shake the entire galaxy!" someone exclaimed, his eyes were hot, it seemed that there was a holy spirit coming down among the gods recently, and in the flood wilderness, there was no saint coming, everyone knew that most of the saints in the flood wilderness had entered the abandoned land, and some of the remaining ones were either in retreat, or their longevity was about to end, or they were too far away to come, they didn't expect that just when they were worried, there was really a saint coming!

"Saints are eternal!" someone shouted loudly, and soon, the voices were joined together, and the whole Tongguan was filled with this sound of cheers.

The Netherworld Demon Lord was calm, staring at the neutron star in the center of Tongguan, and two brilliant divine lights burst out of his eyes: "Where is the Tongguan Immortal King, this saint is coming, why don't you worship?"

Brush, the neutron star shone brightly, and soon, a figure appeared, and then the second and third paths all rushed out of the star where they were, and saluted respectfully to the Netherworld Demon Lord: "I don't know that the adult is coming, and I will miss the welcome, and I ask the adult to forgive me." ”

"It doesn't have to be like this, which one is the Nine Heavens Immortal King?" said the Nether Demon Lord slowly.

The Nine Heavens Immortal King sighed in his heart, he didn't know why this saint who suddenly came up mentioned himself, but in front of the saint, he didn't dare to hide anything, so he could only step forward and clench his fists at the Netherworld Demon Lord, and said, "Junior Jiuxiao, I've seen an adult!"

"Well, you're welcome. The Nether Demon Lord said calmly, "You...... Do you remember a monk named Chu Jun?"

"Chu Jun?" The Nine Heavens Immortal King was stunned, his face changed drastically, and he hurriedly said: "If you go back to your lordship, I do know Chu Jun, he is my disciple, but some time ago, he had already become a deserter and left Tongguan." ”

"Deserter?" "Nether Demon Lord laughed, suddenly stretched out his hand, and grabbed the Nine Heavens Immortal King with one hand: "You told me that Chu Jun would be a deserter? Do you treat me as an idiot? Also, just by you, you are also worthy of being his master? Even I, I am just teaching, I dare not be called a master and apprentice, what kind of thing are you? You dare to say such arrogant words!"

The Nine Heavens Immortal King was bitter in his heart, he never thought that behind a little ant, a huge dragon actually jumped out, if he had known that Lu Zheng had a saint behind him, he would never have done anything to Lu Zheng unless he was full!

Ask for a monthly pass at the end of the month!
