"They went in because I needed their help with something, what are you going to do when you go in?" Cheng Yu said.

"We can go in and help you too!" Xinluo said as a matter of course.

"No need, you can't help with this favor, you can only help them!" Cheng Yu said.

He didn't dare to experiment with someone with such a high realm, after all, his senior brothers and sisters were waiting to help them directly break through to the merger stage.

If there was really no problem with his formation, and the effect was the same as that of the Immortal Demon Tower, then of course he would not object to using them for experiments.

But if you don't even know yourself, then of course you don't dare to ask them for help, if you don't succeed, it will be troublesome.

After all, this formation can only be used once in each realm, but they have not yet reached the edge of breakthrough, and it would be a pity if they were used like this.

However, these disciples were different, they themselves relied on their contributions to obtain such an opportunity for advanced cultivation.

They are still only in the Qi refining stage, but judging from the conditions of these four guards, it is very difficult for them to get such an opportunity by contributing.

That is to say, if they want to reach the foundation building stage, they can basically only rely on their own cultivation, and it is impossible for them to have the opportunity to directly improve their realm.

Now he is using the four of them to do such an experiment, even if the effect of this formation is not as good as that in his Immortal Demon Tower, but for the four of them, it is a very fortunate thing.

"No, what's the help they can help, but we can't help?" Xinhai They obviously didn't believe Cheng Yu's words.

"Believe it or not, you just can't help anyway, you either keep waiting here, or go back quickly!"

"No, I'm going to go in and see how I want to go in today, you've been working on it mysteriously for a month or two, and I don't believe that you're really just meditating, you must have made something new. "Xinluo is not dependent.

He really wanted to see what Cheng Yu was doing during this time, and locked himself in his room all day.

"You all want to see it?" Cheng Yu looked at such a large group of people gathered here, including Chen Hongyuan's brothers and sisters and Ji Yun, who also looked curious, and asked speechlessly.

"Hey, yes!" said Xinhe laughed.

"Okay, let's all come in!" Cheng Yu thought about it, anyway, it won't be a secret here in the future, so it's okay to let them in.

"Hehe, I know that Senior Brother Yu is actually very reasonable!" Xinluo smiled proudly, and slapped Cheng Yu on the back.

"Alright, don't put a top hat on me, I can't afford it!"

The four disciples were very excited to see so many high-level figures of the family who were usually difficult to see, and the head of the family personally ordered the door, so they were even more nervous.

However, although they guarded the entrance to the ninth floor, they had never entered the ninth floor themselves. Now they walked in, saw everything inside, and finally satisfied their curiosity.

In fact, they were very much looking forward to it, the head of the family let them enter this place, did it mean to raise the realm for them? After all, this place would not have any other purpose except for the master of the house to raise the realm for people.

Therefore, almost every disciple of the Cheng family hoped to be able to enter the ninth layer of the cultivation tower under the guidance of the head of the family.

Now that they have got their wish, they are deliberately looking forward to it, only hoping that the world will really fall out of the pie.

With excitement and apprehension, they slowly followed Cheng Yu to the center of the ninth floor! The environment here looked a little strange, it was pitch black in front of them, and the surrounding walls looked a little strange, even a little weird.

It's the heart of them, and as soon as they enter this place, they feel very familiar.

"Senior Brother Yu, how is this place ......?" Xinhai said with some doubts.

This is obviously inside the cultivation tower, but how can it be exactly the same as the inside of the Immortal Demon Tower, this is really a bit strange.

But after all, Chen Hongyuan's brother and sister and Ji Yun were also here, so some of them he didn't say explicitly, but others could understand what he meant.

Cheng Yu smiled and didn't answer his question.

"What do you command, master?" said one of the guards nervously.

"The four of you are guarding such an important place for the Cheng family, although you haven't made much contribution, but for the entire Cheng family, it is a great contribution.

Therefore, in order to reward you today, I am going to deliberately upgrade your cultivation once, as for whether the four of you can break through the realm, it can only depend on your own creation!" Cheng Yu said with a smile.

Cheng Yu's words were very beautiful, and when these four disciples heard the head of the family say such things to themselves, the excitement in their hearts was even more inexpressible in words.

"Thank you for the cultivation of the family master, it is our honor for the family master to let us guard such an important place, and we are willing to sacrifice our lives for the Cheng family!" the disciples said excitedly

They didn't expect that there would really be pies falling from the sky in this world. They guarded such an important place every day, and they had dreamed that they would one day be able to enter it and get the help of the head of the house.

But today, with such a big pie in front of me, everything that is happening now feels like a dream, and it has really come true.

But what they don't know is that they have just become Cheng Yu's guinea pigs. But for them, even if they knew that Cheng Yu was treating them as guinea pigs for experiments, they would still be willing.

After all, this kind of thing is not common, as long as they succeed, their realm and strength will be improved, why not do it?

"It's not as exaggerated as you say, no matter what your cultivation is now, what your realm is? These don't matter, the important thing is that as long as you are loyal to the Cheng family, work hard for the Cheng family, and contribute to the Cheng family, then the Cheng family will not forget you.

As long as you work your own, you don't need to envy others, because what others can have, you will have in the future, even more than they have!" Cheng Yu said seriously.

Although it may be a little unkind to let them do the guinea pigs for experiments, it is indeed a great good thing for these four people, it is not bad for anyone, and it is indeed good for themselves.

"Thank you for the teachings of the head of the family, we will definitely live up to the expectations of the head of the family, strive to improve ourselves, and make more contributions to the Cheng family!" said the four excitedly.

After all, Cheng Yu is like a god to them, and it can be said that Cheng Yu is definitely the idol in the hearts of all the disciples of the Cheng family. How could they not be thrilled to hear their idol owner say such things to themselves?
