The soldier brought the sword purple in, and Ah Jin and Meteor followed. Yuanhang knew that Situ Hao had led a large army to chase after Xiaoliang's soldiers and horses, so he handed over the responsibility of defending the city to Sun Ke.

"Guzhou Fangde, the city must not be slack, ordered the people to close their houses, and not to go out for three days. The marshal goes out of the city to pursue, you need to guard the city in person, and the soldiers in the city must not stop patrolling, and report to me as soon as there is anything. Yuanhang said to Sun Ke with a thousand instructions.

"Your Excellency, just rest assured, if the marshal does not return, the general will not go down to the city." Sun Ke said with his fists clenched.

"Good work general." After returning the salute and sending Sun Ke away, he trotted all the way to find Gu Xin.

In a main room, Gu Xin sent the soldiers away, pointed to an ancient painting and said: "My lord, this is the place where the soldiers have no intention of looking at it, but they see that there is a mechanism behind the painting." ”

"Hmm." Yuanhang answered and stepped forward to take a look. It depicts a scene of several soldiers training. Pick at the painting with the utmost care. I saw that there was a recess inside, and there was nothing else, only a knot, which should be used to pull outward.

"Will there be a mechanism?" Yuan Hang thought that in the past novels, there were always strong crossbows and hidden weapons flying out, and said worriedly.

"This ......" Gu Xin didn't understand, scratching his head and not knowing what to do.

"Go get a piece of rope." Yuanhang was still worried and thought of a solution.

After attaching the rope to the knot, the two of them almost retreated to the door and pulled together. A muffled voice sounded, and a crack opened in the ground, and the two of them threw away the rope and looked down, and the darkness was not visible.

"Sir, I'll fetch the torch." Gu Xin turned around and went out, Yuanhang hesitated, but he still didn't dare to go down alone, so he had to sit aside and wait for Gu Xin.

When Gu Xin came back, he was about to go down with a torch, Yuanhang grabbed him, took a piece of stationery and lit it and threw it down, seeing that it was not extinguished, he let go of Gu Xin and let Gu Xin go down.

"My lord, there is a gate ahead." Gu Xin went down the vertical ladder to the ground, turned around and shone it with a torch, there was only a short passage in front of him, and an iron gate blocked the way.

"I'll take a look." Yuanhang turned and climbed down, and the two of them were already crowded in the small aisle. I pushed the iron door, but it didn't move. Yuanhang knew that this door must not be opened by brute force, took the torch from Gu Xin's hand, and looked around carefully.

Sure enough, on the right side of the iron gate, there is a copper roulette embedded in the wall, which is the same color as the wall, and the corridor is dark, so if you are not careful, you will not find it.

The roulette wheel has four layers from top to bottom, and the middle circle is engraved with four characters, gold, silver, copper and iron. Carved outwards are the southeast, northwest, the third layer is engraved with Chenwu Xuhai, and the outermost is the number three, five, seven and nine. In the middle, an arrow is carved upwards.

"This must be a door opening mechanism, but it's a little complicated and can't be opened for a while." Yuanhang has played this kind of game, but it is a game after all, and there are hints to find the answer, where to find it in the pitch black here.

"Why don't we find soldiers and smash open the iron door." Gu Xin didn't know anything about this, so he could only use some brute force.

"Forget it, let's go out first." After saying that, he handed him the torch and climbed out first. After taking the torch, Gu Xin also climbed up.

"Lock it off and don't let people in." After the voyage was instructed, he withdrew with Gu Xin and went to visit Dao Zi by himself.

Du Wen and Nian You were guarding in the room, and Ah Jin was also in the room, and when they saw Yuanhang coming in, they shook their heads gently.

"He's too tired, he'll be fine after a few days of rest, don't worry." The voyage took a picture of Ah Jin's arm comfortingly.

Ah Jin nodded and said, "I'm here to accompany him tonight, my lord and Meteor are in the same room, let him protect you." ”

"It's okay, there is a guard camp in the house, and there are soldiers patrolling outside the house, you can rest assured to accompany him, I will send someone to bring food later, and you can rest early." After Yuanhang admonished, he winked at Du Wen and walked out of the room, and Du Wen followed.

"Shall we be together tonight? With you, I sleep soundly. "Yuanhang played a scoundrel again, and took advantage of it.

"Humph! I was about to kill you with a single stab. Now Du Wen is familiar with his temperament, but he has taken advantage of it, but he has never acted excessively. Don't you know that it's because she has martial arts, otherwise how could Yuanhang only move her mouth and not her hands.

"By the way, there's something I need you to help me with." Yuanhang remembered the roulette wheel and saw that she was smart, so he wanted to take her to try it.

"What?" Du Wen asked casually.

"Come on." After speaking, he glanced around, reached out and took her little hand and walked forward. Du Wen struggled for a while and didn't break away, her face turned red and she walked out with him.

Jumping into the ground again with a torch, he pointed to the roulette wheel and said, "This is a mechanism, it should be put in place, this door can be opened, have you seen this kind of item?" ”

Du Wen looked at it for a while, touched the roulette, and said, "This should be made by Shang Mu Zhong, the master of Shang Guo's artifact, this person is the best at this kind of object." ”

"Oh?" Yuanhang's eyes lit up, it seemed that she really knew a lot and found the right person. Hurriedly asked, "Is there a way to solve it?" ”

"Yes." Du Wen replied decisively.

"Great, how do you untie it?" Yuanhang seemed to see hope and asked excitedly.

"Find the Merchant Clock." Du Wen replied more decisively.

"You ......" Yuanhang was so angry that he couldn't speak, thinking that he was not her opponent, and endured it.

"It's not that you have to find him, this person will definitely leave a cracking technique to solve the mechanism, and if you can find it, you can also solve it." Du Wen's words brought hope to the voyage, but where to find this cracking technique?

Du Wen picked up the torch and looked around, but there was no clue in the corridor except for the roulette wheel and the wall, so the two had to crawl back into the room.

Du Wen took the torch around the house again, found nothing unusual, turned to Yuanhang and asked, "How did you find this tunnel?" ”

"There is a mechanism behind the painting, and when you pull the rope, it opens on the ground." Yuanhang pointed to the wall and said.

Du Wen turned around and walked to the painting, raised the torch and looked at it. Seeing her so serious, Yuanhang also moved in his mind, could it be that the answer was in that painting? Hurriedly ran over and stood behind her. Du Wen's body fragrance was indifferent, and Yuanhang couldn't help but take a deep breath.

There is nothing special about the painting of a few soldiers training against the sun, and their bodies stabbing their weapons sideways to the right.

"Look at the sun, it's drawn on the top right instead of in the center, why?" Du Wen turned her head to ask Xiang Yuanhang, but found that he was close behind her, if it weren't for the fact that she was a little shorter, she took the initiative to kiss. Immediately said angrily: "Stay away." ”

Yuanhang didn't pay attention to her expression, but was pushed closer by her words, and said: "If this is a hint, it means that it is not noon at this time." ”

The voyage probe looked at it carefully, and silently thought in his heart: up and down, down south, left west, right east. The sun is on the east side, and the sun rises shortly after, and it is the hour of the hour!

Yuanhang happily hugged Du Wen and shouted, "I know, I know, it's the hour." ”

Yuanhang got carried away, hugged Du Wen's softness from behind, turned her neck red, and reflexively turned his left hand and hit Yuanhang in the face.

With a 'snap', the voyage turned around, covered his face and looked at Du Wen in a daze, and asked puzzledly, "Why did you hit me?" ”

To tell the truth, this slap was a little wronged, and I was so excited that I didn't pay attention to climbing the jade peak at all, and I didn't even know what it felt. But how could Du Wen say it, she had to say angrily: "I beat you, how can you get it?" ”

"You...... You're unreasonable. "When did Yuanhang suffer such grievances, but he didn't dare to reprimand him too much, for fear that he would be beaten on this face again.

Seeing his innocent look, Du Wen looked at him in disbelief. Yuanhang just had a little thought, and was slapped by her and lost it, and when he reacted, he forgot the pain, pointed to the painting and said, "This painting is the hour." ”

"Oh." Du Wen also turned around and continued to look at the painting, but her chest felt numb, and her face was hot.

"Look here, all the weapons are pointing to the right, and in terms of orientation, this side should be west." Yuanhang noticed the strangeness in the painting and said with great certainty.

Du Wen glanced sideways at him, and Yuanhang stared intently ahead, not noticing that there was another feeling in Du Wen's eyes.

"But what could it be about metals and numbers?"

"The metal should be iron, only the tip of the gun in the picture is metal." Du Wen was inspired by him and said suddenly.

"Well, it's supposed to be iron, smart." Yuanhang said approvingly, placing his hand on her shoulder. Du Wen opened her small mouth, endured it for a while and didn't reprimand him, but just twisted her body. Yuanhang smiled awkwardly and withdrew his hand.

"Let's go, let's try the rest of the numbers." When Du Wen reached out and grabbed his arm, he said urgently, "No, if this mechanism is wrong twice, it will be locked forever." ”

"Huh?" Voyage to the end, such cleverness? Modern times may not be able to make it.

"I know pull." Du Wen actually jumped up happily, pointed to the painting and said, "Seven, there are seven soldiers on it." ”

"Haha." Yuanhang was extremely excited, and hugged Du Wen and turned around. Du Wen held the torch in one hand and pushed his shoulder with the other. If not, I'm afraid that his face will be on his chest.

"Put me down." Du Wen's face that had just recovered turned red again, this time she was hugged by him, but she was happy in her heart and did not get angry with him.

The two went down to the ground again, and Du Wen was about to flip the roulette, but Yuanhang stopped her, pulled her over, and said, "Beware or there is a hidden weapon, you are behind me." After saying that, he stepped forward and stood in front of her. Du Wen's heart warmed, and she quietly stretched out her hand and grabbed the corner of Yuanhang's clothes behind her.

Aiming all the words of Chen Tie Qixi at the arrow, Yuanhang took a deep breath, pressed down the middle of the roulette wheel hard, and at the same time reached out and back, stopping Du Wen and leaning towards the wall together.

"Quack, quack, quack." A shrill sound came, and the iron door rotated up in the middle, revealing gaps on both sides, and no hidden weapons were seen.

Du Wen knocked his hand off and walked in with a torch. Yuanhang covered his wrists, why did he hit me again? Hey! No, I just touched something, it's so soft. Grinning a little, he hurriedly followed.
