"Well, I'm sure you have that determination! Seeing that formation, you will begin to settle down after you enter. Remember, don't wake up easily after you settle down. The longer you have been in the meditation, the more your cultivation will improve, and the more benefits will naturally be to you!" Cheng Yu nodded, pointing to the formation in the middle and said.

Although the other scenes were expressed through the phantom array, this formation was truly restored according to the formation inside the Immortal Demon Tower.

Because this is the activation array of the Great Yan Inheritance Cultivation Array, without this formation, there is no way for the cultivation array to be opened.

"Yes!" The four of them hugged their fists and walked into the formation excitedly.

Everything they were looking forward to was coming soon, this was the most important day on their path to cultivating immortals, and it was also the day when their path of cultivation really began.

Seeing the four of them sitting cross-legged in the formation, Cheng Yu stepped forward and input the aura into this formation, and the formation suddenly lit up with white light.

Cheng Yu immediately retreated, looking at the extremely similar scene in the Immortal Demon Tower, his heart was also extremely excited.

Xinyun on the side obviously felt that Cheng Yu was a little abnormal, and at the same time, his behavior today also made people feel very different from usual.

Although Cheng Yu is indeed very good to his disciples, he is also a person who pays attention to the rules of things. Since it has been clearly stipulated in the family that only those who have reached the top few in each realm are eligible to get the opportunity to improve their cultivation for them, why did Cheng Yu break this rule?

Moreover, why did he stay here alone for several days, and as soon as he went out, he wanted to improve the cultivation of these four people, this was really unreasonable.

Just now, she had been staring at Cheng Yu, and found that his emotions were obviously a little excited after this formation was activated.

What puzzled her even more was that the formation for improving people's cultivation had always been in Cheng Yu's Immortal Demon Tower? Wasn't this just a disguise? Why is there one here now!

The only possibility is that Cheng Yu is here these days to arrange this formation! In this way, he has made the formation in the Immortal Demon Tower.

In the past, when they were in the Immortal Demon Tower, they had also seen the runes inside, and she had also asked Cheng Yu about the runes in the Immortal Demon Tower, and she only knew that these runes were actually the source of the power of the Immortal Demon Tower.

The reason why the Immortal Demon Tower was able to cast so many powerful formations was because of these runes. I remember that at that time, Cheng Yu also said that he had no way to understand the secrets inside these runes.

She had studied the rune before, and it was absolutely impossible for her to crack the secrets.

But judging from the current situation, Cheng Yu has cracked the secrets in the Immortal Demon Tower, and he has already mastered the power contained in these runes.

If that's the case, doesn't that mean that even if Cheng Yu doesn't use the Immortal Demon Tower in the future, he will be able to exert the power of the Immortal Demon Tower?

Thinking of this, Xinyun admires Cheng Yu even more, this guy will always surprise people.

In fact, Xinyun is not the only one who thinks of this step? Even a guy like Xinhai seems to have discovered something extraordinary.

But he was very smart, because Chen Hongyuan and Ji Yun were there, so although he was curious, he didn't open his mouth to ask the doubts in his heart.

Although Ji Yun and Chen Hongyuan had been here, the two of them didn't know the secrets inside the Immortal Demon Tower, so for the two of them, this was the second time they had come to this place, and the environment here was still the same as before, and there was nothing special.

It's just that they are also a little strange about Cheng Yu's behavior today, and let the four disciples improve their cultivation for no reason, which is really too confusing.

"Now everyone has seen it, I said it a long time ago, there is nothing strange, you just want to come in to see the excitement, now there is no excitement, let you be very disappointed!" Cheng Yu saw that the situation of these four people was very stable, and he was happy in his heart, he knew that his formation was really successful, but he didn't know what the effect would be.

Only after these four people came out of the formation could they simply make a judgment.

"Hehe, how can you be disappointed? Not to mention anything else, we are also very happy to see the realm of our disciples advancing by leaps and bounds one by one!" Xinhai said with a smile.

"In that case, let's all go out!" Xinhe was much smarter and knew that there was indeed something going on, but he didn't say it explicitly, but took the lead in saying it.

"Go out, don't disturb the disciples to break through!" Cheng Yu nodded.

In the past, every time someone came in to improve his cultivation, Cheng Yu would stay inside, so everyone didn't say anything, nodded and all went out.

"It seems that they have seen something!" Cheng Yu shook his head and smiled.

From the way they looked at him, Cheng Yu knew that these people had discovered the abnormality. He may not be at ease with others, but he is absolutely at ease with his senior brothers and sisters, so it doesn't matter if he lets them know about some things.

Chen Hongyuan and Ji Yun, although they have a good relationship, the two of them have always been members of the Chen family and the Ji family. There are still some things that they can't know too much.

Sometimes it's not that Cheng Yu doesn't trust them, but that people's hearts are the most difficult thing to figure out. So in order to avoid unnecessary trouble, it is better not to let them know, in this case, it may be more natural for everyone to be friends.

"Senior sister, have you noticed, that cultivation tower seems to be a little strange!" After separating from the Chen Hongyuan brothers and sisters and Ji Yun, Xinhai and the others returned to their small courtyard, and they asked a little impatiently.

"It's a bit weird indeed!" Xinyun nodded.

"If I'm not mistaken, his cultivation formation seems to be in the Immortal Demon Tower, could it be that Senior Brother Yu moved this formation out?"

"In my opinion, he didn't move out the formation inside the Immortal Demon Tower, but rearranged the same formation according to the formation inside the Immortal Demon Tower!" Xinyun said.

The formation inside the Immortal Demon Tower must have runes to activate, and if there are no runes, there is no way for it to be activated. But today, this formation Cheng Yu did not take out the runes, but directly activated it, which shows that this formation is not the same as the one in the Immortal Demon Tower.

"What? You mean, Senior Brother Yu, he's already cracked the secret of those strange runes?" Xinhai said in surprise.

"There is this possibility, if it weren't for that, he wouldn't be able to find four disciples to try the formation at random!" Xinyun nodded.
