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 likely kill someone to silence him.

"Captain Li, what's wrong with you?" the eldest elder asked softly.

Li Yifei was shocked. His heart was just a little change. The elder realized that he was, and the gap in strength could be seen.

"Nothing, I'm just a little anxious."

The elder smiled slightly and said, "Don't be anxious, this is not a matter of urgent."

Li Yifei nodded and said nothing more. He calmed down his breath, and did not look at another guy who might be the leader, waiting quietly for Xu Shanshan and the others.

For more than two hours, Xu Shanshan and the masked woman in black stopped at the same time. The elder immediately asked, "How is it?"

The masked woman in black shook her head, while Xu Shanshan frowned and said, "I didn't understand. That true energy has been circling with my true energy, and it has no effect at all."

The elder nodded, and then 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 expensive. The more difficult it is to open, the more it proves that the things inside are precious."

"So tired! It seems that they are sucking away the true energy." Xu Shanshan came to Li Yifei's side and sat down, and said tiredly.

Li Yifei held Xu Shanshan's hand and said, "Then let's take a break, there is no other problem, right?"

"No." Xu Shanshan nodded, then sat down to restore her true qi. The innate true qi was not as slow as ordinary true qi. It won't take long to recover Xu Shanshan's true qi.

The masked woman in black sat between the great elder and another man in black. The three of them didn't say much, as if they all knew that such a result would be.

After resting for an hour, Xu Shanshan and the masked woman in black recovered, and before going to the stone wall again, they still retreated after more than two hours.

Xu Shanshan said unhappily: "I said you can't cheat people, right? Is this stone wall just a bottomless pit that absorbs true qi?"

The Great Elder said, "Yes, this stone wall can absorb innate true qi. The innate true qi of ours alone is not enough, so we invited you. We estimate that this requires strong enough innate true qi to fill it up, and then you can open the stone door. But this is just our guess. You can use other methods and do not necessarily have to fill it up all the time."

Xu Shanshan snorted and said, "You came first, then you should have tried other methods, right? You have to share it with me, it takes less effort, right?"

The elder sighed and said, "We came first, and we have come here not only once, but now we have never thought of any other way to use innate true energy to pour it into it."

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

Xu Shanshan said unhappily: "But I feel that I can't fill it up no matter how much I fill it up. If this continues, I will exhaust me to death. It's really not fun. Can't you find a few more people with innate true energy?"

The elder smiled and said, "Miss Shanshan, there are too few people in this world who have innate true qi, and even fewer people can be developed and utilized. We have organized so many years, and there are only one. There are also some people who have innate true qi, but because of the premature breaking of the body, the innate true qi is destroyed, so it is even more rare."

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

The great elder said again: "After the innate true qi is truly formed, you are not afraid of breaking your body, but you are afraid of breaking your body before it is formed, and that will be ruined. Now society is developing too fast, and young people try this kind of thing too early, so some good seedlings are destroyed like this, alas..." As he said that, he sighed again, looking a little annoyed.

Xu Shanshan rubbed her nose, smiled and said, "Do I think I'm a shape?"

"Your natural is formed. Once the innate true qi can reach the state of being released, it is formed."

"Hehe, I was shocked." Xu Shanshan stuck out her tongue.

Li Yifei's face turned dark and said this, wouldn't this mean the matter between the two? But this is his own family matter, and Li Yifei is not afraid that they will know.

In addition, I remembered that little girl Jiang Ningxiang again. I have to tell her about this when I look back. Don’t have a boyfriend one day and then she will lose her body in a mess. That’s a bad thing. Nowadays, the probability of such a thing happening is too high.

The other party obviously prepared for a protracted battle here. At this time, they took out the food and water, and then everyone started eating together.

Li Yifei wanted to take this opportunity to see what these people looked like, but whether it was the Great Elder, the mysterious man, or the woman with a face covering, she would lift up her mask at most and not reveal her face at all. However, when the Great Elder was eating, she showed a white beard below.

This can only be regarded as a characteristic. If there are too many white-bearded men in this world, Li Yifei will recognize this elder unless he fights with him, but it is basically useless to recognize him at that time.

After eating, it soon became dark and the hole was dark. Wu Chang took out a light with a battery and the whole hole lit up.

Xu Shanshan and the masked woman tried for another two hours, but it was still futile and they had to come here today.

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

"Is there anything wrong?" asked the Great Elder.

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

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

Xu Shanshan pulled Li Yi and flew away and walked all the way to the entrance of the cave. It was indeed a very strong mountain wind here, and it was a few meters away from the entrance of the cave. It felt like people were about to be blown away.

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

"Yeah!" Xu Shanshan agreed, and made it convenient directly in front of Li Yifei. Then, after packing it up, he leaned into Li Yifei's ear and whispered: "Brother-in-law, this door is definitely weird."

"Hmm?" Li Yifei looked at Xu Shanshan in confusion.

Xu Shanshan said softly again: "I feel that this is not swallowing our innate true energy."

"What is that?" Li Yifei was quite surprised. Since there were people with innate true qi in the Noah's Ark organization, they had tried it, so couldn't the other party notice it? Or did he deliberately lie to him and Xu Shanshan?

"I can't explain it clearly. Anyway, I don't feel that's the case, so I'm no longer injecting innate true energy so I can't be fooled by them."

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

"Yeah." Xu Shanshan nodded, then frowned again, and said, "In addition, I felt that her true energy was very familiar with Ningxiang's innate true energy."

"Ningxiang?" Li Yifei was stunned for a moment.

"Yes, but although that person's height is similar to Ningxiang, he is a little fatter than Ningxiang, and his breasts are also taller than Ningxiang. Otherwise, I would really think she is Ningxiang."

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

"Well, this is quite possible, but no matter what, I can't be fooled by them. We don't help them open the door this time. Anyway, we have also remembered the route. Wouldn't it be better to come secretly to study it yourself in the future? As long as Ningxiang's innate qi is formed, will it still be necessary for them at that time?"

"Just doing this, it saves a lot of trouble. Anyway, they have been studying here for so long. Even if we can't get it out, it's completely normal."

Xu Shanshan nodded repeatedly and said, "Yes, even if we can't figure it out in the future, it's like letting them get benefits."

"By the way, Senior Murong and the others have not appeared, and I don't know if they have followed him?" Li Yifei said with some concern.

"I feel it's very difficult. The formation is so mysterious. When it comes down, it climbed so far. The chances of them keeping up are too small. We won't help them open it anyway. If they don't come, there's nothing they can do."

Li Yifei thought it was the same. As long as he didn't help them open the door, it would be fine if Murong Yuanqing and the others didn't come.

When the two of them talk, they both put their mouths on each other's ears so that they cannot let the other party hear it. In addition, the wind is extremely strong and the sound is loud, so they still have a clear mind when talking.

When they returned to the cave again, the two of them found a place and set up a tent. They were always carrying this thing, and it was the same for use in the cave. Otherwise, they would feel uncomfortable if they were lying directly on the ground.

When Li Yifei and his friends set up a tent, the elder and the others also went out one after another, obviously they also needed convenience.

However, when the masked woman went out, she was not accompanied by Xu Shanshan, but went out alone. It seems that their organization is not messy, at least these masters are quite normal.
