Fully intelligent assistant cultivation system

"Yes, at least an hour." Cang Jun nodded.

"No, no matter what, I must go down with you." Cang Ying made up her mind anyway.

Cang Jun said helplessly, "Wait, I'll think of a way."

Refining device, refining an oxygen cylinder?

This is not suitable, exercises, yes, it is enough to exchange for a book of exercises, but...

But can this exercise be used?

In any case, let's find a suitable exercise first, so Cang Jun clicked on the system to inquire about the exercise of holding one's breath.

Sure enough, after checking, it was easy to find a low-level exercise, but it was very practical.That is the art of holding one's breath.This mental method is very easy, and it is also very simple to learn, and there are no requirements.

But if this skill is exchanged, can they use it?This is a doubtful question. I have never tried it before, exchanging the secret manuals of mental techniques from the system and giving them to others to use and practice.

"Ding, do you want to exchange for the breath-holding formula?"

"exchange."

"Ding, congratulations to the player for obtaining the breath-holding formula, do you want to learn it?"

Of course I don't study it, if I learn it myself, it's nothing more than tasteless, the Hunyuan Jue that I practiced is much better than this Qi-holding Jue, and I need this Qi-holding Jue.

"Can you take out the breath-holding formula?"

Cang Jun frowned slightly, and tried it.With a thought, the breath-holding formula actually appeared in his hand, but after taking it out, the breath-holding formula has become an ordinary mind method, and it no longer has the special ability that people can learn all at once.

But this also made Cang Jun heave a sigh of relief.With this breath-holding formula, the two girls Cang Ying and Cang Yibo can also dive into the water without worrying about time.

"Second Sister, let's see if this can be successfully practiced in a short period of time?" Cang Jun said, throwing the Qi-holding Art in his hand to Cang Ying.

Cang Ying took a look at it, and found this Qi Qi Jue, she was overjoyed in her heart: "This Qi Qi Jue is just a third-rank Huang-rank exercise, there is no problem at all, just give me half an hour and it will be fine."

"Okay, I'll wait for you." Cang Jun nodded.

An hour passed, and the two women had completely mastered the art of holding one's breath.

The three of them came to the center of the lake together and dived slowly.

It's not easy to communicate underwater, which makes Cang Jun feel rather troublesome.It would be great if it could transmit sound. I don’t know if there is one in the system. Of course, I’m just thinking about it. Now is not the time.

The three of them swam towards the bottom of the lake, and soon came to the entrance of the previous cave.

To Cang Jun's surprise, the hole no longer had the effect of isolating the water before. After thinking about it, he probably took the things inside.

Seeing that Cang Ying was about to go in, Cang Jun shook his head, indicating that he had already arrived.

Seeing Cang Jun shaking his head, Cang Ying also understood what he meant, and the three continued on their way.

Suddenly a bright light in front caught the attention of the three of them, Cang Jun motioned for himself to go first, and they followed behind.

When he came to the bright place, Cang Jun was extremely surprised. There was actually a cave here, but it was different from Lin Jiyao's. It was not as luxuriously furnished as there was, and it didn't have that special ability to separate water.

Cang Jun climbed up without hesitation.

Soon the two girls followed.

"What is this place?" Cang Ying asked.

"It's probably a senior's cave." Cang Yibo looked around at some crude stone tables and benches and said.

Cang Jun nodded, "That's right, this is probably a senior's cave, and this place is very old, obviously that senior is no longer here."

"Let's go in and see what's inside." Cang Ying said with a wave of her hand, rather excited.

"Wait." Cang Jun waved his hand.

Cang Ying stopped, looked at Cang Jun puzzled and said, "What's the matter?"

"If you just go in like this, I'm afraid it's not appropriate. There may be dangers inside, so don't act rashly." Cang Jun explained that in some cultivators' caves, there are often some restrictions, formations and other organs.
