"What's the secret of this piece of black iron?" Ling Yun muttered to himself without thinking.

"You'll find out later, but I'll have to get ready first. The old man said quietly in the dantian.

He put the black iron aside and continued to read the exercises.

"Give me your black iron, and I'll see what it's about. The old man said softly.

Ling Yun sent the black iron into the dantian, and the old man took the black iron, his heart full of excitement.

"I can't think of a solution to this piece of black iron. He asked again.

"It's so fast, you better hurry up and rest!"

"When I have attained enlightenment, I will wake you up. The old man said softly.

Ling Yun's face darkened.

Then he closed his eyes again, and carefully adjusted the Xuan Qi in his body to give full play to it.

It's late at night......

Everyone spends their time in dreams, and as a practitioner, it's normal not to sleep, and even some people stay in retreat for decades.

The Xuan Qi in Ling Yun's body was fully sublimated, which was also due to the effect of the Heavenly Punishment Spirit Seal, after all, it had the power to devour the Xuan Qi of Heaven and Earth.

With such power, it is easy to break through the Triple Heaven.

"I've found it, come and watch it with me! The old man of Zhu Aya held the black iron in the dantian and laughed.

"Well, you've found the secret to unlocking the Black Iron. Ling Yun asked excitedly.

"Yes, this piece of black iron is already related to us, isn't it normal to open it? Otherwise, I wouldn't have asked you to spend a lot of money to buy this piece of black iron. A glimmer of light flashed in the eyes of the old man Takeya, and he waved his long hair slightly.

"Then let's get started! I'd like to see what secrets are hidden in the black iron. He closed his eyes and carefully experienced the technique of the old man in the dantian.

Black iron looks very ordinary, just an ordinary piece of iron, which does not attract anyone's attention in the slightest.

But because it is so commonplace, the secrets contained in it are even less known.

Takeya first cast a forbidden spell, and the seal in the black iron gradually began to disappear.

However, it still resisted stubbornly, giving the intruder no chance.

"I'll see how long you can hold out. The old man cast another forbidden technique. At this time, the black iron was constantly rioting.

However, Black Iron was not so easily defeated, and at this moment, the two sets of forbidden spells she cast were all devoured.

"As I expected, this piece of black iron has the power to devour, and now it's even more interesting. The old man said.

"You're saying that this piece of black iron may be the secret of another spirit seal. Ling Yun suddenly came to his senses.

"It's quite quick, and you can say that, but you won't know until you unravel it. Her fingers lightly pressed on the black iron, and a majestic Xuan Qi poured into the black iron.

Heitie wanted to encounter some familiar feeling, and immediately stopped the riot.

Suddenly, a text appeared on the black iron, and these eight words appeared on it.

"Lord of Devouring, among the stars. ”

These four words represent a very deep meaning, which makes people think a little unthinking.

"Sure enough, it's Devouring Spirit Seal, it looks like you have another task, but this task is a bit difficult. The old man said solemnly.

"You have to reach the Sixth Heaven and open up another space in the dantian, otherwise you won't be able to absorb this Devouring Spirit Seal. ”

Hearing the harsh conditions proposed by the old man Zhu Aya, Ling Yun's heart suddenly sank.

"Oh the Sixfold Heavens! That might have to wait six or seven months!" he sighed softly. However, as for the search for the spirit seal, he had already thought about it from the time he took over the seal trick, and the future road may be to collect and complete the thirty-two spirit seals.

How to understand these eight words. Ling Yun asked.

"It can be considered that on the night of the full moon, the change of the stars, the Devouring Spirit Seal will appear. The old man said lightly.

"The night of the full moon is only seven or eight months. He was a little unwilling. Although his previous cultivation speed was indeed very fast.

However, with each Heavy Heaven after that, the difficulty will increase a lot, so it is not certain whether you can cultivate to the Sixth Heaven within seven months.

"This time is a bit rushed!" Ling Yun scratched his hair a little embarrassed.

"It's not up to me, let it be!" After speaking, she disappeared into the dantian again.

"It's a toss-up. "Lingyun has never been relaxed. He exhaled a sigh of cold air.

"Is this the way of the strong, since it is, then go on!" He is not afraid of all hardships, but if there is a result, all the efforts are worth it.

It's getting brighter......

Ling Yun opened the door, and the two maids outside the door also came to him.

"The prince is early. ”

The two maids said in unison.

His first choice was to go to Yi Sheng's room.

"I haven't gotten up for so long, it's such a big sleeping bug. Ling Yun covered his mouth and sneered softly.

Suddenly, a finger pinched his ear from behind, and Ling Yun cried out in pain from time to time.

"Who are you! let go, let go. Ling Yun screamed in pain.

"Dare to say that I am a big sleeping worm, I see if you dare in the future. Yi Sheng appeared directly behind him.

Ling Yun was stunned for a moment, and explained: "I thought you were sleeping, so I said it." ”

"You still dare to quibble. Yi Sheng screwed his ears again.

"I was wrong, I was wrong. Ling Yun smiled bitterly. Only then did Yi Sheng let go.

"Anyway, why are you going so early?" the former touched his ears lightly, a little hot.

"You didn't even know there was an event today. It is the four major mountain ranges of the Cangyuan Continent that have begun to enroll. Yi Sheng said excitedly.

That's true. Ling Yun was also shocked by this news.

"Really, I was looking for you to sign up?" she grabbed Ling Yun's hand and flew away directly.

"Where are you going to take me?" Ling Yun didn't have such a fast speed, which made him a little overwhelmed.

"Of course, I signed up, but I have to go through the assessment first. She let go of Ling Yun's hand.

They didn't fly long, but at this moment, there was a black crowd in front of them.

It looks very lively, and some of them have even reached the strength of the Four Heavens.

"Wow, how come there are so many people. A flash of alarm flashed in Ling Yun's eyes.

"It's time to sign up, so go sign up!" she whispered.

However, Ling Yun sensed that something was wrong, and looked back at her and said, "Then why don't you go." ”

"I got up earlier than you, and I signed up a long time ago. "Yi Sheng was also ridiculed as a big sleeping bug before. Now I feel that Ling Yun has been slapped in the face.

There were four people sitting in the crowd, and their strength seemed to have reached the Golden Xuan Realm.
