"No, we've seen that rune before, Senior Brother Yu seems to be more difficult to crack that thing than to ascend to the sky, it only took him more than a month to crack this secret?

"Do you think everyone is like you? Senior Brother Yu is already very smart, besides, the Immortal Demon Tower is his magic weapon. He must know more about the Immortal Demon Tower than we do, and if anyone can crack the secret of the rune, he must be the only one who can do it!" Xinhe said.

"Oh, if that's really the case, then wouldn't I have worked for my senior sister for half a month in vain?" Suddenly, Kokomi remembered something very important to him.

Before, he made a bet with Xinmei that Cheng Yu must have done something big for so long in retreat, but Cheng Yu deliberately hit him, and he really thought he had lost.

So for more than half a month, he ran errands for Xinmei every day, and she wanted to eat this worldly one for a while, and wanted to buy that one after another.

But now all this is true, so that is to say, he won this bet, but he did it for more than half a month.

"Who told you you won?" said Xinmei angrily.

"Didn't we all say it just now?Senior Brother Yu has now cracked the secret of the Immortal Demon Tower, isn't this an earth-shattering event?"

"What did Cheng Yu tell you when he came out of the customs half a month ago?

"He was just joking!"

"Really? Didn't he tell you at the time? He didn't do anything big, besides, didn't you guess everything just now? Did he tell you that he had cracked the secret of the Immortal Demon Tower? No, right? So, you just lost this gamble, and you have to help me work for half a month!" Xinmei said with a smile.

"No, this bet should be won by me, although we are just speculating, but now the situation is already obvious, Senior Brother Yu has arranged a formation by himself in the cultivation tower, this is already an indisputable fact!" Xinhai said firmly.

"It's a pity you don't have proof!" Xinmei didn't care at all.

In fact, whether she wins or loses, it doesn't matter to her, and Xinhai has been doing something for her for half a month. It's just that she doesn't want Xinhai to go to that kind of place.

"Senior sister, if you insist on doing this, who will dare to bet with you in the future?" Xinhai must fight for this win or loss, because there are still many beautiful women waiting for him in the world!

"Where did I cheat, you just don't have any evidence. As long as you show the evidence, I will admit that you won!" Xinmei smiled.

"You...... Okay, then I'll wait for Senior Brother Yu to come out in a few days, and we'll reveal the truth!"

"Okay, though, you can't win these days, so you'll have to keep working for me!"

"Hmph, that's impossible, I didn't lose at all, I didn't ask you to compensate for my losses, it's already very merciful!"

"Well, let's wait until you get the proof, but if you lose, you'll have to work for me for another month!"

"Why?"

"Because this time our bet is invalid!"

"Senior sister, I suddenly found that you are too shrewd, you are condescending if you don't do business!" Xinhai said with a look of disdain at Xinmei.

"Yes, I prefer to bet with you rather than in business!" said Xinmei smiled.

"Hmph! I'll never bet with you again, I've fallen for you this time!"

"Whatever you want!" said a nonchalant smile.

————————————————————————

Cheng Yu sat on the ninth floor of the cultivation tower, looking at the four disciples of the Qi refining period, everything was normal, and his nervous heart relaxed.

After all, this was the first time he had arranged the Great Yan Inheritance Cultivation Array, and he wasn't sure if his formation was really right.

But now it seems that he understands everything correctly, but he doesn't know how fast they can absorb aura.

It stands to reason that he had made so many preparations, and even used the spirit crystal as the eye of the Ancient Spirit Gathering Array, which could be described as a double guarantee, and it should be very easy for them to break through.

All four of them are in the late stage of body refining, but for ordinary people, it is a very difficult hurdle to go from the late stage of body refining to the foundation building stage.

Without Cheng Yu's help, it might have been a long time or even years before they could break through. Of course, if they can exchange their contributions for a Tsukidan, they may be able to break through some time earlier.

Originally, he thought that the four of them would start to break through the next day, but until the end of the second day, the four of them still did not break through, which made Cheng Yu a little disappointed.

"If it's in the Immortal Demon Tower, with the cultivation of the four of them, it's almost half a day or a day to break through. But it's been two days now, and they haven't broken through yet, it seems that this formation is not as good as they imagined!" Cheng Yu thought in his heart.

There is no gap, there is no gap, and now Cheng Yu has tried it with four disciples, and it is obvious that he can see the problem. Although on the surface, this formation is not much different from the formation inside the Immortal Demon Tower, but in terms of actual effect, this formation is obviously much worse.

At noon on the third day, one disciple finally began to break through! Then, the other three disciples also broke through!

"Congratulations, you have broken through the first hurdle on the road to cultivating immortals. After this hurdle, you can be regarded as a real beginner monk!" Cheng Yu said with a smile.

"Thank you for the cultivation grace of the master, we will definitely swear to protect the Cheng family to the death and live up to the high expectations of the family master!" The four of them were pleasantly surprised when they felt the great difference between the foundation building period and the qi refining period.

Their qualifications are not good, and they thought that they might not be able to enter the foundation building period for more than ten years. But they never imagined that one day they would be smashed by pies falling from the sky.

"As long as you are loyal to the Cheng family, the Cheng family will never give up on you, and you should not be arrogant because of your shallowness. What others can achieve, you can also achieve, and what others can't, you can achieve. The most important thing is to have an unwavering perseverance!

You have now reached the foundation building period, and there will be more family tasks for you to take in the future, and you will have to accumulate more contributions in exchange for the resources you need.

If you encounter any problems in the future, you can go to the elders and stewards, and they will help you deal with them. If you want to find me directly, you can do it!" Cheng Yu looked at the four people and said.
