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

Little girl, why are you here, cold or not? ”

In fact, Yao Ruixue's appearance here is similar to Lu Feng and Shi Hongfei's guess, because they are not Qi family, and after coming in, there is nowhere to escape, so they can only continue to move forward.

And then I came here, and when I came here, I couldn't find my way out.

As expected, waiting and waiting, the little girl really came.

"It's not cold, I've changed into the thickest down jacket, and before I came in to look for you, I also drank hot ginger tea, by the way, I also brought a bottle here, you and the stone drink it separately, otherwise you will get sick."

Brother, are you hungry or not, if you are hungry, I still have the dry food prepared by Sister Lin Hong here. ”

The snow was too heavy today, and Yao Ruixue had made preparations before deciding to bring Lin Hong in, hot ginger tea and a flashlight, as well as some dry food.

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

I also ate a little bit of dry food casually, and I didn't eat too much.

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

Yao Ruixue's suggestion, Hongfei and Lu Feng had no opinion, because they couldn't find the exit at all when they returned the same way, so they would be trapped here for several hours.

I don't know if Yao Ruixue can find the intersection to get out.

However, Yao Ruixue took them back the same way, still like them, they couldn't find the way they came, shuttling back and forth at several forks in the tunnel, and would come back to the same place, even if they made a mark, it still didn't help.

What surprised them even more was the mark carved with a saber, as if someone had followed them and deliberately erased it.

scared Yao Ruixue a lot.

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

Whatever is scratched or carved on it will disappear within a certain period of time.

And directly use the experiment to prove it to Yao Ruixue, I heard that it is the same thing, and the intuition is really amazing!

"Oh my God, what kind of technology is used to make such a powerful material? If it is used in life, it is so awesome! ”

Indeed, as Yao Ruixue sighed, such a powerful technology, if it is used on the right path, it will definitely cause a lot of sensation.

After all, such technology is what China needs.

"Yes, but I can't study it at all."

Lu Feng and Shi Hongfei studied for a while, but they couldn't get results, and they couldn't see what they were doing at all.

Yao Ruixue said with some regret, and then returned to the room.

After walking back and forth for a while, Yao Ruixue stood up: "No, let me think about it, I always feel that I forgot something." ”

If, as she had guessed, this was the gateway to the Qi family's vault, there should be a mechanism that allowed them to enter officially, instead of staying here and being trapped.

"Wanwan, don't worry, you think slowly."

Shi Hongfei also thought about it, maybe Qi Baishi and Yao Ruixue mentioned it, but she didn't think about it or take it to heart.

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

"Yes, the little girl is not in a hurry, don't embarrass yourself too much. We walked slowly, and we always found the exit, and we went back. ”

Lu Feng also comforted Yao Ruixue, really, watching her pat his forehead, he really felt distressed.
