It is also the center of the entire corridor and statue! The bow and arrow statue seems to be able to sense Zhang Yuning's arrival, bend the bow and arrow, and attack.

"Stay sleeping!"

Zhang Yuning avoided the layers of attacks, floated behind the archer, and pressed hard.

Behind the archer, there is a fist-sized button.

The button was pressed, and in almost a second, the entire fourth floor was quiet and became calm.

The city walls slowly dissipated, and all the attacks that were about to fall disappeared.

The green light in the statues' eyes disappeared, they put away their weapons, sank into the stone wall again, returning to calm, as if they had never moved.

I returned the war in the last second, but I was calm the next second.

Seeing them gradually recovering from peace, Tang Kai and Jiang Xue breathed a long sigh of relief and were sweating profusely.

It was really too dangerous just now. If Zhang Yuning was a little slower, they would probably be done.

I have to say that Zhang Yuning made great contributions this time.

Zhang Yuning came over lightly and said proudly: "Master, you can't deny my excellence this time, right?"

Tang Kai nodded and said, "It seems that Miaomiao is really the right choice to ask me to take you with me. If it weren't for you, this layer would probably have stuck us. Thank you."

He looked at the wounds on his body to a greater or less, and felt scared.

Compared with the first three, the fourth floor is not on the same level.

This means that one stage is more terrifying and difficult to deal with.

Now that the fourth floor is just so dangerous, there are the fifth floor, the sixth floor, the seventh floor... As long as you think about it, Tang Kai felt his scalp numb.

Fortunately, this layer is not unsolvable, and they quickly walked to the end.

There is no danger along the way.

After passing the bow and arrow statue, Tang Kai looked shocked and asked, "What exactly is this bow and arrow statue?"

He just saw that these statues had no power source or mechanical clockwork. How did they move?

Moreover, it can attack others. What is the principle?

This statue is much more awesome than many machine artificial intelligence. Iron Man's Mark armor is probably not that awesome.

"I don't know, I just can move anyway."

Zhang Yuning frowned and said that she didn't understand either.

Tang Kai had no choice but to give up discussing this issue, pushed open the door to the corridor lens, and headed towards the fifth floor.

The underground palace here is very strange. Each floor is a downward stone staircase and you must go down one by one.

Moreover, in many cases, there are no night pearls above the stone steps, so the road is completely unaware.

Fortunately, Tang Kai used a backup of the glow stick and flashlight to help Jiang Xue explore the way.

He has a perspective eye and can completely see at night, but Jiang Xue cannot.

"Is this underground palace connected to the outside world?"

Jiang Xue suddenly asked.

"How do you say that?"

Tang Kai was stunned.

"According to normal principles, the deeper we go underground, the less oxygen, the more carbon dioxide we will be, and we will be unable to breathe. However, the more we go down, the more oxygen we feel, in other words, underground, and connected with the outside world."

River Snow Road.

Tang Kai suddenly understood what she was going to say, and his eyes lit up, "That is, we can't go back from the main entrance, we can continue down so that we can find the exit?"
