But Li Yifei didn't dare to observe the person carefully. If the other party knew that he had such an idea, and if he really guessed it, the other party would probably kill him.

"Patriarch Li, what's the matter with you?" the elder asked softly.

Li Yifei was secretly horrified. It was just that his heartbeat had changed a little. This great elder realized that he was aware of himself, and the difference in strength was evident.

"Nothing, just anxious."

The elder smiled slightly and said: "Don't worry, this is not an urgent matter."

Li Yifei nodded, and stopped saying anything, calmed his breath, and did not look at the other guy who may be the leader, quietly waiting for Xu Shanshan and the others.

For more than two hours, Xu Shanshan and the black masked woman closed their hands at the same time, and the elder immediately asked, "How is it?"

The black-clothed masked woman shook her head, while Xu Shanshan frowned and said: "I didn't understand, that zhenqi has always been turning around with my qi, and it has no effect at all."

The elder nodded, but at this time he seemed calm, and said, "That's normal. If this stone wall is so easy to open, it means that the things inside are not very valuable. The more difficult it is to open, the more it proves the things inside. precious."

"It's tired! It seems that the true qi is about to be sucked away by them." Xu Shanshan came to sit next to Li Yifei and said a little tiredly.

Li Yifei took Xu Shanshan's hand and said, "Then take a rest, there are no other questions, right?"

"No." Xu Shanshan nodded, and then sat down to recover his true qi. Innate true qi does not recover slowly like ordinary true qi. It won't take long before Xu Shanshan's true qi will recover.

The black-clothed masked woman sat between the great elder and the other black-clothed man. The three didn't say much, it seemed that they all knew that there would be such a result.

After an hour's rest, Xu Shanshan and the black-clothed masked woman both recovered, and before going to the stone wall again, more than two hours later, they still retreated.

Xu Shanshan said uncomfortably: "I said you wouldn't be a pitman, right? This stone wall is simply a bottomless pit that **** real breath."

The elder said: "Yes, this stone wall is able to absorb innate true qi. We are not enough innate true qi, so we invited you. We estimate that this requires strong enough innate true qi to fill it up. Then you can open the stone gate, but this is just our guess, you can also use other methods, and you don't have to keep filling in the true energy."

Xu Shanshan snorted and said, "You came first, so you should have tried other methods? You have to share it with me. It takes less effort, isn't it?"

The elder sighed and said: "We came first, and we didn't come here just once, but now we don't think of any other way except thinking of instilling innate true energy."

When Li Yifei heard this, he was surprised. It turned out that the other party had come here more than once, but there was no news from China, which shows how powerful the Noah's Ark organization is.

Xu Shanshan said uncomfortably, "But it feels like I can't fill it up at all. If this continues, I will be exhausted. It's really not fun. You can't find more people with innate anger?"

The elder chuckled and said, "Ms. Shanshan, there are too few people in this world who have innate instincts, and there are even fewer people who can develop and use them. We have organized for so many years, and there is only one. Some people, even if they have innate qi, but because of their premature break, that innate qi is also destroyed, so it is even more rare."

Xu Shanshan said "Ah" and then looked at Li Yifei.

The elder said again: "After the innate true energy is truly formed, it is not afraid of breaking the body. I am afraid that it will be broken before it is formed. Then it will be ruined. Now the society is developing too fast, and young people try this too early. This kind of thing, so some good seedlings are destroyed in this way, sigh..." He sighed and looked a little annoyed.

Xu Shanshan rubbed her nose, smiled, and said: "Then I am considered to be formed?"

"Your nature is formed. Once the innate true Qi can reach the state of exuding, it is formed."

"Hey, it scared me." Xu Shanshan stuck out her tongue.

However, Li Yifei's face turned black. When he said this, wouldn't it be a matter between the two, but it was his own family affair, and Li Yifei was not afraid that they would know.

In addition, I thought of that little girl Jiang Ningxiang again, and she had to confess this matter to her. Don’t let her make a boyfriend someday, and then she broke down in a daze. That would be a bad thing, young people nowadays, it happened. The probability of such a thing is too great.

The opponent obviously made preparations for a protracted battle here. At this time, they took out food and water, and then everyone ate together.

Li Yifei wanted to take this opportunity to see what these people look like, but whether it’s the elder, the mysterious man, or the woman with her face covered, she wears a mask at most when eating. When he lifted it up a little, he didn't show his face at all, but when the big elder was eating, he showed a white beard underneath.

This can only be regarded as a characteristic. There are more men with white beards in this world. Unless they fight against them, Li Yifei can recognize this great elder, but at that time, it is basically useless.

After eating, the sky soon darkened, and the inside of the cave was also dark. Wu Chang took out a lamp with a battery, and the whole cave lit up.

Xu Shanshan and the masked woman tried for another two hours, but in vain, they can only get here today.

"Brother-in-law, you go out with me." Xu Shanshan pulled Li Yifei.

"What's the matter?" the elder asked.

Xu Shanshan rolled her eyes and said, "I was puzzled. You eat and drink too. Why don't you want to go to the bathroom?"

The great elder was speechless and said: "Be careful, the mountain wind is very strong outside at this time."

Xu Shanshan dragged Li Yi to fly out and walked to the entrance of the cave, where the mountain wind is indeed very strong, and a few meters away from the entrance of the cave, it feels like people are going to be blown away.

Li Yifei immediately said, "Shanshan, right here, it's too dangerous outside."

"Yeah!" Xu Shanshan agreed, and went directly in front of Li Yifei for some convenience, and then gathered up and whispered in Li Yifei's ear: "Brother-in-law, this is definitely weird."

"Huh?" Li Yifei looked at Xu Shanshan suspiciously.

Xu Shanshan said softly again: "I don't feel this is swallowing our innate true qi."

"What's that?" Li Yifei was a little surprised. Since there are people in the Noah's Ark organization who are innately innocent, they have tried it too. Could the other party not notice it? Or deliberately lie to him and Xu Shanshan?

"I can't tell, anyway, I don't think it's that way, so I don't enter the innate anger so much now, and I can't be fooled by them."

Li Yifei thought for a while, and said, "You are right. You know this matter better than me. Just make the decision."

"Yeah." Xu Shanshan nodded, then frowned again, and said: "In addition, I also felt that person's true qi just now. I actually felt that she was very innocent and very familiar with Ningxiang's innocence. The anger is somewhat similar."

"Ningxiang?" Li Yifei was taken aback.

"Yes, but although that person's height is about the same as Ningxiang, he is a bit fatter than Ningxiang, and his chest is taller than Ningxiang, otherwise I really think she is Ningxiang."

Li Yifei thought for a while, and said, "That's impossible, it should be that the innate true qi is not much worse. If you feel her innate true qi, then it feels similar to Ningxiang's."

"Well, it's quite possible, but no matter what, I can't be fooled by them. Let's not open the door for them this time. Anyway, we also remember the route. We will come and study it by ourselves in the future. It's not better. As long as Ningxiang's innate true energy is formed, they are still needed at that time?"

"Just do it, it saves a lot of things, anyway, they have been researching here for so long, even if we can't fix it when we come, that's completely normal."

Xu Shanshan nodded repeatedly and said: "Yes, even if we don't understand it in the future, it's better than letting them benefit."

"By the way, Senior Murong and the others haven't appeared, and don't know if they followed?" Li Yifei said with some worry.

"I find it very difficult. The big formation is too mysterious, and when it comes down, they climbed so far sideways. The chance for them to follow is too small. Anyway, we won't help them open it. They won't come. Nothing."

Li Yifei thought about it, as long as they didn't open the door for them, it wouldn't matter if Murong Yuanqing and the others didn't come.

When the two talked, their mouths were attached to each other's ears so that they could not be heard by the other party. In addition, the mountain wind was extremely strong and the voice was loud, so when they spoke, they still had a bottom in their hearts.

When they returned to the cave again, the two of them found a place and set up the tent. This thing had been carried on their backs, and it was the same for use in the cave. Otherwise, it would be uncomfortable to lie directly on the ground.

When Li Yifei and the others set up the tent, the Great Elder and the others also went out one after another. Obviously, they also needed convenience.

However, when the masked woman went out, it was not like Xu Shanshan accompanied by someone, but went out alone. It seemed that their organization was not messy, at least these masters were quite normal.

When they got into the tent, Li Yifei and Xu Shanshan hugged each other and fell asleep. The other party wanted to clean them up, so there was no need to use sneak attacks, so they didn't need to worry at all.
