"It's nothing, I just accidentally injured my leg, it's not serious.

Little girl, why are you here? Are you cold?"

In fact, the reason why Yao Ruixue was able to appear here is similar to Lu Feng and Shi Hongfei's guess, because they were not the Qi family. After they came in, they had nowhere to escape and could only continue to move forward.

Then I walked here and after I came here, I could never find my way out.

As expected, waiting, the little girl really came.

"It's not cold. I've changed into the thickest down jacket. Before I came in to find you, I also drank hot ginger tea. By the way, I also brought a bottle here. You and Shi Tou drink it separately, otherwise you will get sick.

Brother, are you hungry? If you are hungry, I will have the dry food prepared by Sister Lin Hong."

The snow was too heavy today. Yao Ruixue made preparations before she decided to bring Lin Hong in with her, including hot ginger tea, flashlight, and some dry food.

He took out the lid of the thermos bottle and let Shi Hongfei and Lu Feng drink more than half of it, leaving a small part.

I also ate a little dry food, but I didn't eat too much.

"Then let's go back as the same way. Sister Lingling and I walked like this before."

Yao Ruixue's comments were made without any objection, because they could not find the exit when they returned according to the original route, so they were trapped here for several hours.

I wonder if Yao Ruixue can find the intersection to go out.

However, Yao Ruixue took them back the same way, and was still the same as them. She could not find the way she came. She shuttled back and forth at several forks in the tunnel and returned to the original place. Even if they made marks, it would still be useless.

What surprised them even more was the marks left with a saber, just like someone following them and deliberately erasing them.

It scared Yao Ruixue.

It was Shi Hongfei who told her that the walls on the tunnel had been specially treated and could not be left behind.

No matter what is scratched or etched, it will disappear within a certain period of time.

And I directly used experiments to prove it to Yao Ruixue. I heard that it was the same thing, but it was really amazing intuition!

"Oh my God, what kind of technology is used to make such powerful materials? If it is used in life, it would be so awesome!"

As Yao Ruixue sighed, such powerful technology would definitely cause a lot of sensation if it was used on the right path.

After all, such technology is what China needs.

"Yes, but it's impossible to study."

Lu Feng and Shi Hongfei studied it for a long time, but they could not get the results. They could not tell what they were doing.

Yao Ruixue said with some regret, forget it, and then returned to that room.

After walking back and forth, Yao Ruixue stood up: "No, let me think about it, I always feel that I have forgotten something."

If she had guessed that this was the intersection of entering the Qijia treasury, there should be an agency that could allow them to enter formally instead of staying here and being trapped.

"Wanwan, don't worry, think about it slowly."

Shi Hongfei also thought of it. Maybe Qi Baishi and Yao Ruixue mentioned it, but she didn't think about it carefully or took it to heart.

Qi Baishi can tell Yao Ruixue the precise location of the vault, which means that the method of opening the vault also told Yao Ruixue.

"Yes, little girl is not in a hurry, don't make things too difficult for yourself. Let's walk slowly, and we can always find an exit and go back."
