A dragon groan suddenly sounded, resounding through the sky, and the black dragon turned his head to the mysterious old man and said, "Thank you, senior." ”

After speaking, he took a deep look at Yun Cheng, and then said: "He will see each other day and cloud, I hope you will not be so weak." ”

After the black dragon finished speaking, he suddenly jumped up, directly hit the mountain wall above his head into a big hole, and then disappeared at the end of the sky.

This scene was so shocking that Cloud City was still in a deep shock until now.

After a while, Yun Cheng said to the mysterious old man: "Senior, what is the origin of this bead, why did he promise to help me after seeing the bead." ”

"You'll know when the time comes. Now know that it won't do you any good. After the mysterious old man finished speaking, his body slowly faded away.

What Yun Cheng didn't know was that at this moment, the Heavenly Star Academy was already all shocked, because just now, the Heavenly Star Tower suddenly shook and left, as if it was about to rise from the ground and leave directly, and this process lasted for more than a dozen breaths before it slowly stabilized.

Under the cliff, Yun Cheng shook his head and was about to leave, but was reminded by the mysterious old man: "You stupid fork, you don't take any good things and leave?"

Yun Cheng was stunned, "What good thing?"

Suddenly, he seemed to think of something, and looked at the big chains in the distance, "Senior, you don't mean those chains!"

"What else do you think I'm talking about?"

Yun Cheng smiled and walked to the chain in the distance, he suddenly picked up a broken iron chain, but in an instant, Yun Cheng instantly threw the chain on the ground.

"Senpai?"

The mysterious old man playfully said, "Can't you pick it up?"

Yun Cheng looked at the iron chain, "Senior, this iron chain is a little special, the moment I picked it up, I suddenly felt that my cultivation was suppressed greatly. ”

"Nonsense, this is made of black meteorite, black meteorite is in this realm, you can't see it in the second place at all, it can instantly suppress the release of vitality, and it is also a good weapon advancement material. ”

Weapon advanced materials, as soon as he heard this, Yun Cheng looked at the black iron chain again.

The mysterious old man continued, "It is of great help to cultivate the physical body, and at the same time, integrate it into the Tianyan Sword, because the Tianyan Sword has now been refined by you and belongs to you, so when you use it, he is not suppressing your vitality, and when you use it against the enemy, the opponent will be different." ”

Hearing this, Yun Cheng was instantly overjoyed, and looked at the black iron chains, but there were tons of black iron chains here, and they were big.

Yun Cheng continued to pick up the small section it had just thrown to the place, feeling the suppression of the vitality, it was okay at first, but after a while, basically his vitality was suppressed so that he couldn't release it at all.

Yun Cheng was very satisfied, he put all the black iron chains into the Heavenly Dao Enhancement Tower, and Yun Cheng asked, "Senior, how should I integrate this black meteorite into the Heavenly Flame Sword?"

The mysterious old man was silent for a moment and said: "The black meteorite is a special strange thing in the universe, with the ability of this realm, it can't be melted at all, just put it away first, and when your strength is reached, everything will fall into place." ”

Yun Cheng nodded, did not continue to dwell on this matter, since he did not have the strength, he worked hard to improve his strength.

Feeling the trace of dragon energy left by the black dragon, Yun Cheng thought about it, and he decided to stay here to improve his strength.

Yun Cheng found a place to sit cross-legged, and with a wave of his arm, a bunch of amethyst appeared around Yun Cheng, and Yun Cheng began to absorb frantically, feeling the continuous rich vitality in the Spirit Sea, and Yun Cheng absorbed more and more hard.

The surrounding amethyst began to turn into powder at a speed visible to the naked eye, and when all the amethyst in front of him was absorbed, Yun Cheng swung out a bunch of amethyst again.

In this cultivation continent, what is the most precious? Of course, it is cultivation resources, only if the cultivation resources are sufficient, even if a person with ordinary qualifications, the cultivation comfort will be accelerated, and what can hinder them is only the threshold before breaking through.

Ten days later, when all the amethyst in front of Cloud City turned into powder, a more powerful aura appeared in an instant, and the second layer of the Star Yuan Division arrived.

Yun Cheng did not stop, but became even more crazy, and after another twelve days, another breath of breakthrough appeared, with enough resources, Yun Cheng took twenty-two days, directly from the first layer of the Xingyuan Division to the third layer of the Xingyuan Division, he cultivated the invincible Heavenly Decision, and when he broke through, there was basically no obstacle.

Yun Cheng opened his eyes, feeling the surging aura in his body, and Yun Cheng smiled.

"Yes, barely a little bit of my demeanor. At this moment, a voice sounded, naturally a mysterious old man.

Yun Cheng smiled: "Senior, how powerful are you at your peak?"

Yun Cheng was very curious, he only knew that the mysterious old man was very strong, but how powerful it was, he didn't know, and he didn't have any concept.

The mysterious old man was silent for a moment and did not speak, and just when Yun Cheng thought that the mysterious old man would not speak, the mysterious old man spoke: "Your world, I can destroy it with my hand." ”

Yun Cheng's eyelids jumped after hearing this, "I'll go, won't one day a strong person suddenly destroy this realm, right?"

The mysterious old man smiled and did not speak.

Suddenly, Yun Cheng thought of something, "Senior, since you are so powerful, can you take me back?"

"Go back?" the mysterious old man smiled, he naturally understood what Yun Cheng said about going back.

The mysterious old man said: "Now that I am limited to this tower, it is not impossible, but. ”

"Senior, but what?" As soon as he heard the mysterious old man say that he could go back, Yuncheng was excited, he had been in this world for more than a year, and he missed his hometown abnormally, and he didn't know how sad his parents would be after they couldn't find him.

Of course, in addition to his parents, Yuncheng also has a younger sister who is two years younger than him.

Hearing Yun Cheng's inquiry, the mysterious old man sighed, and then said, "There are two ways to go back, one is to wait for your strength to break the void, find the location of the earth by yourself, and then go back." ”

"The second method is for me to urge the Heavenly Dao Enhancement Tower again, forcibly shatter the void, and lead you back. It's just that even if it's the second method, your realm must reach the Star Emperor level, otherwise, it will be shattered by the space. ”

When Yun Cheng heard this, he was a little anxious, "Senior, even if I use foreign objects to resist, can't I? By the way, I still have the power of the earth." ”

The mysterious old man whispered, "No, without the strength of the Star Emperor, I won't help you urge the Heavenly Dao Enhancement Tower to send you back." ”

Yun Cheng was silent, he knew that the mysterious old man was for his good, and after a while, Yun Cheng said, "Okay, senior, I'll continue to work hard." ”

The mysterious old man smiled, and then said, "Next, you have one more important matter. ”

Yun Cheng was stunned, "What's important?"
