"But one thing is needed." Shen Nian said with a smile, but there was a trace of evil in that smile.

Shen Nian turned his head and smiled at Chu Yan.

Mu Bai stood in front of Chu Yan, "Little witch, what are you doing, why do you want to come to me." ”

Chu Yan looked at Mu Bai who was blocking in front of him and smiled silently.

Shen Nian rolled his eyes, "My brother Yan is still here, what can I do." ”

Gao Lingyan was very happy about the sentence "My brother Yan" and expressed his happiness.

"Chu Yan, bring me your hair." Shen Nian stretched out his hand.

Chu Yan's expression became even more strange, and he took off the hairband and handed it to Shen Nian.

Shen Nian took the hairband and smiled, "Do you remember who gave this headband?" ”

"It was sent by the elder brother." Chu Yan suddenly remembered and said.

Although the three of them are three different masters, they are very familiar with each other and often come and go, because Murong Xun, that is, the unequaled son, is the oldest, so Shen Nian, Chu Yan and Mu Bai all call him senior brother.

"Yes."

Shen Nian untied the brocade on the belt, and saw that the inside was wrapped together by cloth of unknown material, tightly wound, and inside were elastic threads that were bent together with each other.

Shen Nian shook off all the lines, and it was thirty or forty meters.

"This line is very tough, and the general fire, sword, and sword are constantly moving. And the elasticity is very good, it can be extended for hundreds of meters. Shen Nian tied one end of the thread around Gao Lingyan's waist and the other end around his waist. In case of any emergency, Gao Lingyan can quickly jump back onto the iron plate.

"Alright." Shen Nian tied the thread, straightened his waist and said.

Mu Bai and Gao Lingyan looked at Chu Yan's expression now, as if they were looking at a baby.

The corners of Chu Yan's mouth twitched.

Shen Nian cut off the piece of his hair band hanging down, handed it to Chu Yan, and asked the other party to tie up his hair.

"Brother Yan, be careful when walking from the side wall. I've just discovered that there's a good chance that this side wall also harbors a mechanism. So be careful. Shen Nian's eyes were full of concern.

Gao Lingyan touched Shen Nian's head, and the corners of his mouth raised slightly.

Now there is no way back but to move forward.

Gao Lingyan stretched the thread on his waist to see the elasticity. Then charge up and go straight to the side wall.

So fast. Chu Yan sighed in his heart, what a beautiful figure. The fastest body technique he had ever seen was Murong Xun's, but now it seems that Gao Lingyan and Murong Xun's martial arts are only comparable.

As soon as Gao Lingyan stepped on the side wall, the four of them heard the sound of the mechanism activating. But Gao Lingyan's body technique was too fast, and he had already stepped on this place, and the mechanism in this place and the opposite one shot arrows in an instant at the same time. But they were all just missed. didn't shoot Gao Lingyan, and didn't even touch the corner of his clothes.

Waiting for Gao Lingyan to turn over last, he used the arrows in the air to borrow his strength and jumped onto a small stone platform in front of the stone gate. The arrows stopped.

The four of them looked at the dense arrows on the wall and couldn't help but sigh in their hearts. It's such a powerful organ, if it weren't for Gao Lingyan's fast body, I don't know how the four of them should pass this level, even if they can pass it, I'm afraid they won't be completely unharmed.

Gao Lingyan just stepped onto the small stone platform, looked around, and then gestured from Shen Nian to indicate that it was okay. Shen Nian let out a long sigh. The moment the mechanism was activated just now, she really wanted Gao Lingyan to come back.

Now the threads on the two of them have been straightened, but they are not yet at the limit.

Gao Lingyan looked at the stone door, and then according to Shen Nian's teaching, pressed the protruding place on the stone door, only to hear a click, the stone door opened, Shen Nian and the others only felt that the stone cave began to shake, especially because now they were standing on the iron plate, and the two hooks of the iron plate were on the stone wall, so the three of them felt it particularly obviously.

I saw a path rising from below, connecting the original cave entrance and the stone gate where Gao Lingyan was. The path rises from the water below, and there is still some water.

Shen Nian and the others were all shocked, they didn't expect the organs here to be so amazing.

Shen Nian waited for the path to stabilize, and then listened to the sound of no other sounds around, so the three jumped off the iron plate, the three of them fell on the path, did not move, felt it, and after feeling it, it was indeed fine, Shen Nian took back the iron plate, folded it, and changed back to the appearance of the belt, but unfortunately the silk was broken.

"I'll go back and fix it for you." Shen Nian said to Chu Yan, and then handed the belt to Chu Yan.

Chu Yan had a strange expression on his face, which showed that he was still speechless about this life-saving "belt".

Mu Bai immediately took it, stuffed it into his arms, and said, "I won't take it for you." ”

Chu Yan smiled, looking at Mu Bai's cute appearance, the corners of his mouth raised.

The three of them immediately came to Gao Lingyan's side, the stone door had been opened, completely open, and there was a long corridor inside. On both sides of the corridor are lit candles.

Xu was because he received the air outside, so it ignited in an instant.

Shen Nian first studied the patterns on the stone door, touched the lines, and then took a closer look, "It is indeed a sign of unintentionality." ”

"Then let's go inside. I'm super curious right now. Mu Bai said.

The four of them walked into the stone gate, and then the stone door slammed shut.

Shen Nian had a premonition about this, so he didn't take it seriously.

The stone gate was closed, and the candles on both sides of the corridor were lit. I can't see the road ahead.

"Nian'er, you see there's a mural here." Gao Lingyan asked Shen Nian to come and see.

Shen Nian and the others all looked at the wall, indeed, what was painted on it was the story of the opening of the Eastern Dynasty, the founding emperor and how Wuxin fought and how to settle down. The stories are ordinary, nothing special. They are all stories from picture books that have been circulated in the Eastern Dynasty, and several people know it. Even the children of the Eastern Dynasty Kingdom have a picture album of how the Eastern Dynasty Kingdom was founded.

There are frescoes on both sides of the stone wall, and they are exactly the same.

"Look at the degree of pigment residue and technique of painting, it was painted by one person." Shen Nian said after checking the paintings on both sides.

The four of them walked for a while and found that there was no mechanism. But the four of them still did not relax, still tense their spirits. In this way, the four of them raised their vigilance and walked to the end of the corridor, there was no door, no pattern, no mural, just an ordinary wall.

The suddenly tense nerves of the four of them were stunned for a moment.

"I'm not mistaken." Mu Bai walked up and looked at it carefully, and touched it.

Shen Nian also stepped forward, looked carefully, and knocked on the stone wall. Mu Bai moved out of the way so that Shen Nian could have a good check.

As a result, Shen Nian stood up straight, looked at the three of them, waved his hand, and looked helpless: "It's really an ordinary stone wall."

"But? Why? That's not the same as usual. Mu Bai asked strangely.

Shen Nian shook his head, Chu Yan and Gao Lingyan also stepped forward to check, and then gave up, it was indeed an ordinary wall.

"So what now? We're not going to be stuck here, are we? Mu Bai asked.

Shen Nian began to feel the wall and walked back, "Impossible, so many mechanisms, coupled with the strangeness of Mingyue Lake, there must be a secret here, since it is not an exit, it is estimated that the exit is in these murals." And ......" Shen Nian stopped and looked back, looked at the three of them, and said calmly: "If there is really no way, then it can only," Shen Nian brushed his eyes to the side, coughed twice, "Blow one up."

"Blow one?" Mu Bai said with wide eyes.

Gao Lingyan strode in front of Shen Nian, "Nian'er." The voice was quite serious.

Shen Nian lowered his head and looked away.

"Nian'er." Gao Lingyan accentuated his tone and shouted again. Reach out at the same time.

Shen Nian touched his nose and took out two "Boom Thunder" from his arms. He smiled flatteringly, blinked, and put it in Gao Lingyan's hand with an embarrassed face.

This time, even Chu Yan's face changed.

"Nian'er, you actually brought thunder with you?" Chu Yan asked.

"Little witch, you really deserve this name." Mu Bai covered his face.

You must know that when the two of them saw Shen Nian take out the two thunderbolts from his arms, they were really more shocked than when they saw "Jiao".

Gao Lingyan still looked at Shen Nian with a serious face, angry at him, how could this little girl dare to bring such a dangerous thing on her body. What if it was in case, in case, in case something happened.

Gao Lingyan's eyes became darker and darker.

Shen Nian bit his lower lip, not daring to look up at Gao Lingyan. After a while, he quietly looked up at Gao Lingyan, and saw that Gao Lingyan still had a serious face.

"Brother Yan." Shen Nian tugged on Gao Lingyan's sleeve.

Gao Lingyan didn't speak, but still looked at Shen Nian.

Shen Nian coquettishly, "Brother Yan, I was wrong, I didn't have a good next time." I promise. Shen Nian blinked his eyes wide, pouted, and raised his hand to swear.

Gao Lingyan directly held Shen Nian's hand that he was about to swear, pulled Shen Nian into his arms, and sighed, what should I do with you. That's good, I can't control it now. Alas.

"Alright. Brother Yan. I promise, there will be no next time. Then he added, "Even if there is a next time, I will tell you in advance if it is okay." Shen Nian was coquettish.

Gao Lingyan sighed, "Dare to have a next time." Gao Lingyan lowered his head, his eyes stared directly at Shen Nian's eyes, and his deep eyes seemed to suck Shen Nian in.

Shen Nian's heart was pounding, and he said in a daze: "Okay."

Mu Bai Chuyan turned around when Gao Lingyan hugged Shen Nian just now, and now he heard that Shen Nian and the two of them seemed to be fine, so he turned around.

Gao Lingyan stuffed the thunderbolt into his arms. Shen Nian grabbed Gao Lingyan, snatched the thunderbolt from the sky, and put it on the ground. Just now she saw Gao Lingyan stuffed into her arms, and finally realized Gao Lingyan's mood just now, she was really worried.

Gao Lingyan had a smile in his eyes, but his face was still serious.

"Then, Nian'er, what now?" Mu Bai asked.

Shen Nian touched his chin, paced back and forth, and said, "Actually, I felt that something was wrong just now."

"But what's wrong?" Shen Nian took two steps to look at the murals on both sides, and took two steps to see.

The three of them didn't speak, they just followed Shen Nian, in case something happened, so that they could protect Shen Nian as soon as possible.

Shen Nian lowered his head, touched his chin, and looked at the marble under his feet and fell into deep thought.

The three of them didn't speak, and they all waited patiently for Shen Nian.

The four of them didn't notice how much they trusted and understood each other.

"Ahh Shen Nian suddenly raised his head and looked at the three of them, his eyes flashing, "I finally know that something is wrong." ”

The three of them waited for Shen Nian to explain.

There are the same paintings painted on both sides of the stone wall, but it is said to be symmetrical, Shen Nian walked forward as he spoke, and the three of them followed as usual.

"But," Shen Nian stopped and looked back at the three of them, "I walked somewhere just now, and I found that although the murals on both sides are the same, they are asymmetrical. But it wasn't obvious, so I didn't notice it in the first place. ”

"Asymmetry?" Mu Bai said.

"Yes. This proves that there is an extra stone on one side of the wall. Shen Nian nodded.

"But what's more?"

"This is it." Shen Nian pointed to a stone on the left-hand side, that is, on the right hand side of Gao Lingyan and others, and the four of them looked at this stone at the same time, only to see that Wuxin was painting on the stone as if he was sacrificing on an altar.
