Lu Nan has already gone to explore the way forward. Xiao Lintian had said before that the mechanism of the underground palace is very complicated, so he should not take risks easily.

When Lu Nan walked to the turn, he saw a door and followed Xiao Lintian's instructions and did not dare to go in.

He stood a few meters away from the door, trying to see if there were any traps around him.

But the road at the door is the same as the road at where he is standing. It is paved with bluestone slabs, and there is nothing wrong with it.

And the door seemed to be embedded in an authentic wall, with no gap at all, and the two heavy doors were also closely linked without any gap at all.

Lu Nan moved slowly, and only walked for a meter, suddenly his feet were empty, and the bluestone suddenly separated, and Lu Nan felt his body sinking.

He jumped up in fear, hit his head on the top of the hole, and shot out a few hidden arrows from the walls on both sides.

Lu Nan was still quick-witted and his body slanted, and he slid back almost.

But even so, Lu Nan was still shot in the shoulder.

He quickly turned over and sat up, turned around in shock, and saw that the walls on both sides were closed, and the bluestone slab that he had fallen just now was still open.

With a puff, a hole appeared on the top of the underground palace, and a child fell down, making a giggle and laugh.

Lu Nan immediately raised his sword and looked like he was defensive.

"This is just a preheating. There is no poison on the arrow. It is intended to remind you that the levels in the future will become more and more difficult. You may break your hands and arms, or even die!"

"If you don't dare to challenge it, it's the shore to turn around!"

"Gagaha...it's the shore when you look back!"

The child laughed a few times and then shrank back.

But Lu Nan had already seen it clearly that the child was not a real person at all, but just a puppet the size of a child.

Its mouth opened and closed just now, revealing the metal machinery inside.

This is the mechanism that the old palace master of Xingluo Palace has arranged long ago, and these sounds have also been set in advance.

But how did he do it? After hundreds of years, can he still use it freely?

Lu Nan was curious and wanted to hit the top of the cave again and grab the puppet and study it.

But he dared not take risks easily.

Hearing that the arrow was not poisonous, Lu Nanshu breathed a sigh of relief, pulled out the arrow, and quickly took out the wounded medicine given by Ling Yu and applied it on.

As soon as he bandaged it, Xiao Lintian and the others came over.

"Lu Nan, are you injured?"

Zhao Xuan asked with concern when he saw that Lu Nan had not worn his outer clothes and there was blood on his inner clothes.

Lu Nan quickly told several people what had happened just now.

Qin Shan learned to refine weapons at Qinglong Academy, and Xiao Lintian gave him the mechanisms collected by the Lord of Silver Wings.

Qin Shan studied hard and although he dared not say that he had become a master, he still understood the general mechanism.

"It's a puppet that I didn't see the puppet with my own eyes. If I saw it, I might know how it was made!"

Qin Shan saw that the bluestone slabs below were still open, so he slowly walked forward.

"General Qin, be careful not to fall into trouble!" Lu Nan was worried that he would touch the agency, so he quickly reminded him.

"It's okay, the puppet dolls come out to remind you that the levels that will be more and more difficult, which proves that as long as you are willing to continue moving forward, the next level will be opened!"

Qin Shan walked to the open bluestone slab, looked down and saw a disc rotating hand one meter below.

He was about to reach out and turn the disc, but after thinking about it, he shouted, "Pei Yu, give me your sword!"

Seeing that Qin Shan was not in danger, Pei Yu hurriedly walked up and handed him his sword.

"You back first!"

Qin Shan waited for Pei Yu to retreat before he took his own sword and Pei Yu's sword and stretched it out.

Two swords replaced the hand, and turned the disc, and saw the door in the middle slid open to both sides silently.

"Success!"

Qin Shan excitedly withdrew his sword and saw the bluestone slabs closing.

This level represents passing.
