Vol 2 Chapter 1217: . Isn’t it the only way?

"This is the tunnel that people dug underground during the War of Resistance Against Japan..." The baby began to speak.
But Long Ying is the same as Feng Che, do you understand it, but you probably know the meaning of tunnel war...
The three of them were walking and chatting, but they didn't feel particularly bored, but Feng Che found that the place where they came in should be on the left side of Heijing just now. The three of them have walked for almost three hours, and the road ahead is still endless. They are not walking in a straight line, they have encountered several turns...
Feng Che couldn’t help but began to observe the surroundings carefully. They said that the secret road that they walked was about two meters and five meters in height and one meter in width. The blue marble was added, and the sides and the top of the head were black marble. Feng Che I feel that this is definitely not congenital, it must have been built by someone...
After walking another distance, Feng Che suddenly said, "Master, we are not walking right!"
"Huh? No? What's the matter? Isn't it the only way?" Long Ying said, looking at Feng Che when he heard the words, and even the baby looked at Feng Che in confusion.
"It looks like there is more than one way here, either I misunderstood, or there is another way here..." Feng Che said with squinting eyes.
"What's going on, daddy?" The baby looked at Feng Che curiously and asked.
"Just now I felt that we had been walking for so long before we reached the end, so I always felt something was wrong, so I was looking around carefully. Look, the surrounding area of ​​our location cannot be congenital at first glance. It should be Someone trimmed it out the day after tomorrow, and I saw this scratch here just now, but now it has appeared again. Either it may be that there are many scratches like this, very common, or it may be that we have been spinning around in place..." Feng Che looked at the baby and Long Ying and explained.
Long Ying and Bao Bao looked at where Feng Che was pointing, there was indeed an obvious scratch on the wall...
"We didn't think so much before. We thought that there was only one way, and we just walked all the way. Now it seems that we are careless. We make a mark around and then walk around..." Long Ying frowned and thought.
Feng Che and the baby had no objection, so the three of them made a few marks around, and then continued to move forward. After an hour, the three of them returned to their original place...
"It seems that we are really trapped, and we have been spinning around, but what is going on? There is clearly only this way..." Long Ying looked at the mark she left before, very depressed. Said.
"Baby, is there a formation?" Feng Che also looked carefully for a long time, but found no problems, so he looked at the baby and asked.
"I'll take a closer look, I haven't seen the traces of the formation for the time being..." the baby said after hearing the words.
So the three of them continued to stop in place and began to look for it earnestly. The baby looked carefully for a long time, but did not find the formation, so he frowned and said, "Daddy, there is no formation, is there any mechanism? It will be fine if my mother is here..."
"Organization? What do you mean, baby?" Long Ying asked curiously.
"It's a mechanism, my mother said before that there are some treasure vaults and so on, there will be mechanisms that can confuse the enemy after opening! It is similar to the formation method, but not the formation method..." The baby thought carefully after hearing this. Said, every time she encounters a problem, she misses her mother...
