"But I'm always a little worried, can they really stop the Netherworld from attacking the human world?" Xin Yao looked at the five soul marks on Cheng Yu's palm, but she was always not so relieved in her heart.

Think about it, the safety of their human world is now placed on a few ghost kings, which makes it difficult for her to accept. And after they returned to the underworld, Cheng Yu didn't know what they wanted to do, so there would be a lot of variables.

"I can understand your thoughts, but don't overcomplicate things, sometimes things are far less complicated than you think. Sending these ghost kings back is just one of the ways to deal with this catastrophe, maybe they can't stop those ghost kings from attacking the human world, but I believe that these guys still have the ability to delay time.

As long as they can delay the time for the Netherworld to attack the human world, we may already have the ability to solve this disaster by that time, so senior sister, don't worry too much!" Cheng Yu persuaded.

"Maybe you're right, and I hope things are as you think. I won't blame you anymore for cultivating ghost cultivators. But you have to be careful not to make such a mistake again. Fortunately it's me this time, if someone else discovers this secret, then you're really finished!" Xin Yao looked at Cheng Yu and said seriously.

Originally, she would never allow Cheng Yu to cultivate ghost cultivators, but when she came in and saw everything here, coupled with the fact that Cheng Yu learned from the ghost cultivators that the netherworld was going to attack the human realm, she suddenly felt that cultivating these ghost cultivators did not seem to be completely useless.

At least Cheng Yu's approach is still very right, first control the life and death of these ghost kings, and then let them go back to go undercover to prevent the underworld from attacking the human world.

If it weren't for the fact that Cheng Yu happened to be able to cultivate and control these ghost cultivators, I believe they wouldn't have learned the news that the Netherworld was about to attack the human world.

Now that they know the news, they can prepare early. Coupled with the fact that those five ghost kings went back to obstruct it, I believe that there is no way for the Netherworld to end the civil war in a short period of time.

It's best to let them fight for a long time, especially if they let their ghost cultivators suffer heavy losses, in this case, they won't have the strength to attack the human world at all. And even if the civil war was over, it would be impossible for them to gather a large number of ghost cultivators to attack the human world for a while.

However, although she did not object to Cheng Yu cultivating an army of ghost cultivators now, she was still worried that this secret would be discovered by others. After all, this is not a joke, she can understand Cheng Yu, but that's what others think.

"Senior sister, you can rest assured. I'm not stupid, if I hadn't sent them back to the Netherworld this time, how could I have let you find out?" Cheng Yu said with a smile, as long as Xinyao didn't object to it anymore.

As for others, he will naturally be more careful, and if he really lets others find out, he will not admit it. After all, he is not like the man in black, who cultivates ghost cultivation by using himself as a host, in that case, he will become the same as ghost cultivation.

And even if he cultivated more than 80,000 ghost cultivators, he didn't have the slightest aura of ghost cultivators on his body, which was fundamentally different. So even if someone finds out that he has something to do with ghost cultivation, there is no way for him to admit it to others.

"What do you mean, if I hadn't found out on my own, you would never have told me about this?" Xin Yao said as she stared at Cheng Yu.

"Senior sister, don't get me wrong, I thought about telling you, but I think telling you about this will only make you more worried, so I can't help but not tell you!" Cheng Yu said embarrassedly.

"Then I won't be clear if you explain it to me well? Look at you, don't you explain it to me clearly now! You obviously don't want to tell me!" Xin Yao said dissatisfiedly.

When Xinyao also had a little woman, as Cheng Yu's woman, she naturally wanted her sweetheart to share everything with her. Although she could also understand Cheng Yu's thoughts, she couldn't help but lose her temper.

"Senior sister, this is a great wrong, when you helped me suppress ghost cultivation many times, I actually wanted to tell you, but I never had the opportunity. Isn't it the providence of God that you bumped into me this time? And if you think about it, I didn't even say anything about them, and now only you know, and this is a secret that only the two of us know. Cheng Yu took Xinyao's hand and said with a smile.

"Then who else knows about this matter except me?" Sure enough, the thoughts of a woman in love are difficult to describe in words, listening to Cheng Yu's explanation, her heart suddenly felt much better, especially when she heard that several other women didn't know.

Women are like this, although they are used to having so many women around Cheng Yu. Usually everyone gets along very well and is very harmonious, but there are some things that we always want to compare.

It doesn't matter if all the women don't know. But now that Xinyao is the first to find out, she naturally has to compare with other women. When Cheng Yu told her that the others didn't know, her heart suddenly felt a lot more comfortable.

It's as if Cheng Yu is telling her that she is the most important of these women.

However, for Cheng Yu, it is not so complicated. He didn't want to tell everyone, he just didn't want everyone to worry about him, and it wasn't that he told which woman was more important.

Moreover, Xin Yao was also discovered by her by mistake, so Cheng Yu had no choice but to tell her everything. But in Cheng Yu's heart, these women of his are all equally important, and they will not be less than any other.

Of course, Xin Yao doesn't care what Cheng Yu thinks, she just needs to think what she thinks in her heart, and she is comfortable in her heart.

"How can I say this casually, except for you, there is no third person who knows!" Cheng Yu couldn't see Xin Yao's careful thoughts, and said with a smile.

"In that case, you can't tell a third person about this matter, and you can't tell them about it!" Xin Yao felt much better, although Cheng Yu didn't take the initiative to tell her about it, but at least she was the first person to know about it.

"Okay, Senior Sister has the final say, I promise not to say it to anyone again!" Cheng Yu said with a smile.

How could he talk about this kind of thing casually, not that he didn't trust his women, but this kind of thing, the less one person knows, the more safe, the more one person knows, the more worried.

"In that case, let's get out. Xin Yao nodded.

Out of the Immortal Demon Tower, the two tacitly found an antelope, slapped it to death, and the two took the antelope back with a smile.

Although Xin Yao discovered this matter, Cheng Yu's heart was much more relaxed, perhaps because someone could discuss the matter of ghost cultivation with him in the future!
