Lu Chen forgot about it and thought about it at this moment.

The death knot of the Flying Immortal Swordsmanship, the most headache since ancient times, in that year, the system owner got this exercise, after research, found the inappropriateness of this set of exercises, and wanted to change it, but he has not found a suitable method.

In the end, because of the sudden turmoil in the Nine Realms, the matter was put down.

Originally, he planned to study this set of swordsmanship after quelling the turmoil in the Nine Realms to find out the cause of the dead knot.

As everyone knows, the turmoil in the Nine Realms was too huge, and the system owner did not expect it in advance.

In a hurry, the owner of the system put the porcelain set of swordsmanship in a secret and dangerous place, intending to go here to overcome this difficulty after the turmoil is over.

However, what the system owner did not expect was that this Nine Realms turmoil had been fought fiercely for a whole thousand years.

That great battle swept the entire Nine Realms into it, and the entire Nine Realms were almost crippled and turned into a wasteland.

It was also during that period that by chance, the young Flying Immortal Ancient Emperor stepped into that secret realm, obtained the Flying Immortal Swordsmanship, and achieved great cultivation, starting his legendary life.

When the turmoil in the Nine Realms fell into a bitter battle, and the two sides were evenly matched, a peerless god king appeared, which was enough to turn the tide of the battle.

Discovering the young Flying Immortal Ancient Emperor and performing the Dacheng Flying Immortal Swordsmanship, the system master suddenly realized, so he accepted him as a closed disciple, and helped him get through the death knot with his own supreme means.

The name of the Flying Immortal has also spread throughout the Nine Realms, making countless people admire and revere him.

In the memory of eternity, all kinds of situations came to mind, making Lu Chen suddenly understand why Nie Cang needed the Phantom White Worm so much.

You must know that the master of the system back then used the Phantom White Worm as a guide, and used supreme means to steal the sky and change the day, so as to open the death knot of the Flying Immortal Ancient Emperor, so as to make his Flying Immortal swordsmanship go to the next level.

"It's right to ask for the Phantom White Worm, and it's not wrong to use it!" Lu Chen nodded, "It's just that with you, you can't get out of the dead knot of the Flying Immortal Sword Technique at all, and in the end it's a void after all!"

You must know that although the owner of the system used the Phantom White Worm back then, he also used other things, and each one was no worse than the Phantom White Worm.

"How can you know if you haven't tried!" Although Nie Cang knew that the success rate of this kind was very small, he still had a glimmer of hope for luck.

Once he succeeds, then he will go one step further and become a generation of quasi-emperors, and he will be one step away from the Flying Immortal Ancient Emperor, and he will not be his successor in vain, and he will fall into his name.

You must know that with the realm that Nie Cang has now, with the addition of the Flying Immortal Sword Technique, he can walk sideways in the entire Nine Realms, even the supreme existence of some forbidden areas, and he does not dare to test his edge.

With his strength, he has long been famous in the Nine Realms, which is the envy of countless people.

However, he didn't, just because of the dead knot of the Flying Immortal Sword Technique, he didn't want to ruin the reputation of the Flying Immortal Ancient Emperor because he didn't go to the dead knot, so he never made his identity public.

Instead, he went incognito and kept looking for a solution.

In the entire Nine Realms, the people who knew his identity were also guessed like Lu Chen, not told by Nie Cang.

"The descendants of the Flying Immortal Ancient Emperor, speaking of which, we can be regarded as having a relationship, I can help you get through the knot of death!" Lu Chen's eyes looked directly at Nie Cang, the eyes of life and death were bright, and his eyes fell on Nie Cang, making him seem to be completely naked in front of Lu Chen, as if in his gaze, he could see through the ancient and modern future.

"The emperor has conditions, right?" Nie Cang said.

"Yes!" Lu Chen nodded.

"Sure enough!" Nie Cang smiled wryly, knowing that there was no such thing as a free lunch in the world.

Even the guardians behind the Nine Realms of Eternity are the same.

"You can choose to agree, or not, I won't force you!" Lu Chen said slowly.

"Do I have a choice?" Nie Cang said dejectedly.

I have a hundred years left in this dead knot, and if I don't succeed, I can only die.

Let him choose, of course he chooses to live, and to live is to agree to Lu Chen's request, any request.

This was his helplessness and had to compromise.

The times create heroes, and at the same time, the times will also create villains, and in this world, there are many things that you don't have to choose.

"No matter how you choose, I will help you get through the dead knot, you don't have to be entangled!" Seeing Nie Cang's entanglement, Lu Chen smiled slightly and said.

"Really?" Nie Cang raised his head abruptly and looked at Lu Chen with a shocked expression.

"Words must be practiced!" Lu Chen said solemnly.

"I believe it!" Nie Cang nodded, for thousands of years, the emperors of the past dynasties have been a promise, and this will not be fake.

"Emperor, please speak!" Taking a deep breath, Nie Cang showed a posture of listening.

"I don't need you to do much, just let you promise me one thing!"

"What?"

"At this time of the Great Turmoil of the Nine Realms, I hope you will be the vanguard!"

"The Great Turmoil in the Nine Realms?" Nie Cang's expression was stunned, and he suddenly changed color.

"Is there really going to be another turmoil?"

Every time the emperor appears, there will be a great turmoil in the Nine Realms, and the legends of the ages linger in his ears, immediately bringing Nie Cang back to his senses.

"I promise!" Nie Cang nodded solemnly, the safety of the Nine Realms is everyone's responsibility, even if Lu Chen doesn't say it, he will do his best to protect it.

This is the responsibility of every being of the Nine Realms.

What's more, if he passes the death knot, the Flying Immortal Sword Technique will definitely go further, and at that time, even if he doesn't take the lead, he won't be able to.

"Okay, happy!" Lu Chen had long expected that he would agree.

"The Phantom White Worm is for you, I won't leave immediately after the Medicine Dao Conference, when the time comes, you come to me, and I will help you open the dead knot!" After speaking, the light in Lu Chen's hand flashed, and three Phantom White Worms fell into Nie Cang's hands.

Immediately, Nie Cang felt the space around him for a while, and suddenly the boiling voice came, and he hurriedly put away the Phantom White Worm.

Glancing up at Lu Chen, Nie Cang clenched his fists slightly, bowed his head slightly, and then turned around and walked into the crowd.

On the edge of the medicine field, an old Taoist priest appeared again.

Lu Chen glanced at it slightly, and at a glance he recognized that it was just a puppet stand-in secret technique.

"Let's go, find a place to rest for a while, and wait for the Medicine Dao Conference to start!" Lu Chen beckoned to Ming Yi and the others, and then took the group away.

"Hey, why are you leaving, master, don't go, you still haven't confiscated me as an apprentice!" The surrounding people saw that Lu Chen and his party were gone, and hurriedly chased after him, and said in pieces.

"If you really don't want to take me as an apprentice, give me a phantom white omen worm and send me away, I'm very content, one worm is enough!"

"Yes, yes, for a bug!" a group of people called out unashamedly.
