Cheng Bo didn't say anything. After all, no matter how much they wanted to learn Guwu, the final decision on this matter was still in Hua Shu's hands. As long as she didn't nod her head, they would say nothing more.

"Do you have any concerns?" Song Zihao is not stupid. Seeing her hesitation, you know that this might not be feasible.

Hua Shu sighed, and said in a serious tone: "What I and Chang Chang are practicing is not the ancient martial arts you think, but the more advanced techniques, human greed, we can't teach things about our cultivation, if you want to join us To cultivate, you must be aware of the absolute confidentiality of your parents and relatives."

"A more advanced technique? Not Gu Wu?" Song Zihao was a little confused, and Gu Wu still had advanced techniques, what kind of exercise was that?

"No."

"Can't you tell your family at all?" Song Zihao was a little unacceptable. After all, he loved his parents. He didn't know why he couldn't tell them.

Hua Shu shook his head firmly, "No."

"Why? Can I know the reason?" Cheng Bo also couldn't understand. What is human greed can't be known, what is the amazing technique?

Looking at them deeply, Hua Shu let out a long sigh. The two men were still young, and they were very curious. If they didn’t tell them the reason, they might not be able to understand the seriousness of the matter at all. Maybe this is just one thing. Opportunity, she can take the opportunity to test them.

"I can tell you, but you must swear that everything today will never be known to anyone other than the four of us present."

Hua Shu didn't hesitate anymore. If the two of them didn't control their mouths, she would just erase their memories. She can still do such a small thing now.

"Okay, I swear." Song Zihao agreed without hesitation.

Cheng Bo nodded, "I can swear too."

Therefore, the two swear an oath together, regardless of whether they both took the oath seriously, since they took the oath, Hua Shu will give them the answer.

"The answer you want to know is very simple, because Dong Chang and I are not ancient martial artists, but immortal cultivators. What we practice is the method of immortal cultivation." Hua Shu smiled slightly, "I believe that even if I don't explain, you can understand. What is Xiuxian?"

"Xiuxian? This..." Song Zihao looked weird, "Isn't this something in myths and legends? You won't tell us that Xiuxian really exists, right?"

Hua Shu raised his eyebrows, "The ancient martial arts exist, why can't Xiuxian exist?"

"Uh..." Song Zihao was speechless. Indeed, just as she said, Gu Wu is also something in the novel. Since it exists in reality, why can't Xiuxian exist?

"The life of the cultivator during the refining period is two hundred years. When reaching the foundation period, the life span is increased by three hundred years, while the golden core period is increased by five hundred years, and the subsequent stages are even longer. Shou, do you think, how many mortals can withstand the temptation of longevity?" Hua Shu looked serious and glanced at them lightly.

"Human nature is greedy, for the sake of profit, you can do nothing to fight for you to die or die. If you know the existence of a cultivator... Before you have enough ability, let people know your identity as a cultivator, it is no different from a child holding gold. Brick, you are a second-generation official and a third-generation rich. It shouldn't be difficult to imagine the consequences, right?"

Cheng Bo was born wise. He immediately understood what Hua Shu said. Even because of his childhood education, he knew more about the conflicts and secret struggles that occurred under the interests of Hua Shu, and therefore it was easier to understand Hua Shu’s. Scruples, and the importance of the secret of the cultivator. But in the same way, he also heard another meaning from Hua Shu's words.

"You mean that if we are strong enough, we can tell our family members, or even let them practice together?"

Hua Shu smiled slightly, and was able to immediately hear the meaning of her words, which is indeed a good brain wave.

"You guessed it right. As long as your cultivation is high enough, strong enough, and able to protect your family, then someone knows that you are a cultivator, and those mortal methods are no longer useful to you, so naturally you don’t need it. No matter how cautious it is, of course, what I'm talking about is only for the secular world, and for other monks in the immortal world, you still have to be careful."

"The world of cultivating immortals? Is there any realm of cultivating immortals?" Song Zihao was shocked again, is this world still what he saw?

At this moment, he felt that his worldview had undergone earth-shaking changes. The world suddenly became so unfamiliar, as if he had lived in this world for more than ten years.

"Yes, there is another world of cultivating immortals besides the secular world we are familiar with." Hua Shu replied affirmatively, not at all surprised seeing the shocked appearance of the two of them.

When she was just reborn, she was also shocked when she saw the Xuan Tianzhu Space and Mo Jue. At this moment, she understood their feelings very well.

After a while, the two of them finally digested the amazing information they received today. Although the idea of ​​learning from Hua Shu has not decreased but increased, it is a matter of great importance. They also pay more attention to them, and they think they need to think carefully before doing it. Make the final decision.

"I need to think about it. I can't guarantee that I can be tight-lipped about my family now." Song Zihao spoke first.

Of course he can't wait to learn the exercises, but after all he gets along with his parents day and night, and he has such a personality. He really has no confidence in himself. He thinks he should think carefully and make a decision after he has a thorough understanding.

Cheng Bo has almost the same idea, "I also need some time, and I will make a decision after I clarify my thoughts."

"I have no opinion. This is a major event related to your life. Of course you need to consider it seriously." Hua Shu didn't care about their final decision. Whether they were worried or worried, she would wait for them to make a decision. It's not too late to think about it.

"By the way, I would like to remind you that the oath is not empty talk. Breaching the oath is to bear the consequences. Even if nothing happens when you are alive, you will bear the consequences after you die. Therefore, it is best not to forget the oath you just swore. !"

Hua Shu chuckled his lips and chuckled, looking at them with crooked eyebrows, with undisguised cunning in his eyes.

Song Zihao and Cheng Bo looked at each other, their expressions were a little weird, and then they felt helpless.

They were calculated by her? To be honest, they really didn’t take the swear seriously. Although they didn’t intend to break their promises and tell others what happened today, they always thought that swearing was nothing but nothing at all. Now I listen to Hua Shu’s It seems that this is not the case?
