Xu San lit a cigarette and took a puff, although it was not a good choice to smoke in a place like a cave with poor air circulation, but Xu San really needed a cigarette to calm down.

There is a way that wealth is moving, and seeing that the things he has been pursuing for several years are about to be seen, Xu San really can't hold back the excitement in his heart - although he doesn't know what will be in the treasure cave, but the things hidden in the treasure cave that will let the ancestors of the Xie family use a whole piece of mutton fat jade as a key should be several times, dozens or even hundreds of times more than that whole piece of mutton fat jade.

Xu San stared at Zheng Zheng and smoked unhurriedly. For a few moments, he felt sorry for this young man, it was not easy to have such an achievement at such a young age, and it was indeed a pity to die like this. But it's even more a pity who let him get involved in this matter, since he has this matter, there is nothing to say.

To apologize...... Then give him a happy death.

Zheng Zheng fiddled with the key inserted into the wall with his back to Xu San, and he held the handle of the key and turned it left and right for a while, but this move was in vain. The "key", as always, did not turn a single inch.

"Tsk......"

Xu San felt disappointed for a while, took a hard puff of cigarette and threw away the cigarette butt, took a step or two forward, and opened his mouth to say something - there was no point in wasting time in vain, it was better to find out what Zheng Zheng knew first and then kill him, and then take some time to find the next person who was good at breaking through the mechanism.

Click...... Click......

The two sounds, which seemed to be circlip starting, and the sound of gears turning, stopped Xu San's pace of progress. His eyes widened suddenly, and he looked at Zheng Zheng, who was kneeling in front of the stone wall, in disbelief: he ...... Really did it?!

Wang Si and Xiao Wu, who were standing behind Xu San, also stood up suddenly, the two soft sounds were not loud, but they could hear them clearly in the small and quiet space of the cave.

When the "click" sound came, Zheng Zheng's heart was also moved, but he was not happy but frightened, and in an instant, the cold sweat on Zheng Zheng's head came down. He subconsciously looked overhead, and the expected situation had not yet appeared, which made him feel a lot more relieved.

"You...... How did you do it?" Xu San suppressed the ecstasy in his heart and asked, "The treasure cave has opened?"

Zheng Zheng turned his back to Xu San, shook his head and said, "There is a small hole down here, and it seems that there is a mechanism that can be pushed into...... I tried it and it looks like it works. But the treasure cave hasn't been opened yet, so I'll have to try again. ”

As he spoke, Zheng Zheng slowly twisted the grip of the "key", and this time, the "key" that had never been turned was gently turned in everyone's eyes with a "rattle" sound.

Zheng Zheng twisted the "key" but felt that the feeling in his hand had changed, he let go of the grip of the "key", but saw that the "key" began to rotate slowly, accompanied by a "bang" and "dong" muffled sound, I don't know what mechanism was involved.

"This ......" Xu San looked at the rotation key, listening to the muffled sound echoing in the cave from nowhere, and was a little clueless for a while. He wanted to ask Zheng Zheng, but remembered that Zheng Zheng didn't know what the situation was. After coming back to his senses, Xu Sanyi grabbed Xie Miao's hair and pulled her face face to himself. Xu San asked sharply, "What's going on?...... Is it normal?!"

"I haven't been in the treasure cave, how do I know. Xie Miao said expressionlessly, and the pain of her hair being pulled didn't seem to be felt at all.

Xu San stared at Xie Miao fiercely, and Xie Miao stared at him with empty eyes. After a while, Xu San let go of Xie Miao and let her still kneel on the ground and kowtow. Looking at Xie Miao's empty eyes, Xu San could be sure that this woman was really dead, and it seemed that she felt that the ancestral treasure cave was finally going to be discovered and was powerless and frustrated.

"Quack quack...... Bang ......"

A muffled sound finally put an end to the tooth-aching sound of the mechanism, and the self-rotating "key" also stopped, silently inserted into the stone wall.

At this moment, the cave seemed extraordinarily quiet.

Xu San took a deep breath softly and walked to the stone wall where Zheng Zheng was kneeling. He looked at the stone wall left and right for a while, but he didn't notice any change, so he asked Zheng Zheng, who was kneeling, "What's the matter? Wasn't that sound just now the sound of opening this gate?"

"It should be......" Zheng Zheng sat on his knees steadily, his left hand still on the ground, and his index finger stuck in a small hole under the stone wall. He looked up at Xu San, frowned, and said, "The next thing should be to pull out this key, this kind of key should not be a one-time consumable, maybe this door can be opened after pulling out the key." ”

As he spoke, Zheng Zheng stretched out his hand, wanting to pull out the key. Xu San on the side frowned, stretched out his hand, hugged Zheng Zheng, and said in a deep voice: "Since this is the case, then let me open this door, and I won't bother you." ”

Xu San did this with his concerns. Now the door of the treasure cave is only one step away from opening, what if Zheng Zheng rushes in first after opening the treasure gate? Or Xie Miao has been pretending to be stupid all along, but secretly told Zheng Zheng the method of locking the door from the inside after entering the treasure gate, wouldn't that be more troublesome? Xie Miao is the real heir of the Xie family after all, and he must know more about this treasure cave than him, and the relationship between Xie Miao and Zheng Zheng is better than the relationship between himself and Xie Miao, it is really difficult to say whether Xie Miao said something to Zheng Zheng. This kind of thing, you can't be unguarded.

"Good. Zheng Zheng nodded and withdrew his right hand.

Seeing this, Xu San reached out and wanted to pull out the key, but before he could touch the handle of the key, his brows furrowed again. He glanced at Zheng Zheng, who was kneeling on the ground, and said secretly in his heart: "Tsk...... There are no mechanisms in the cave, but no one can say whether there are any mechanisms in this treasure cave, and what if as soon as I open the treasure cave, a mechanism will appear and shoot me into a sieve?"

He looked at Zheng Zheng, who was safe and steady, and then at Xie Miao, who had been kowtowing in the direction of the gate of the treasure cave, and his heart was shocked: "What if there is really a mechanism here, and they deliberately want to lead me to open the gate......

Thinking of this, Xu San's face was cloudy, his eyes swirled back and forth between Zheng Zheng and Xie Miao, and his heart was mixed.

"Big brother...... Wang Si saw that Xu San was not moving, and couldn't help but greet Xu San.

"Tsk. ”

Xu San thought about it left and right again, gritted his teeth, and beckoned to Xiao Wu on the side: "Xiao Wu...... You come here. ”

Xiao Wuyi was stunned, put down the things in his hand, and walked to Xu San's side. Xu San pointed to the "key" inserted in the wall and said to Xiao Wu in a deep voice: "You come to open this door." ”

Although he didn't want to admit it, the fact was that Xu San was still cowardly at this juncture. He didn't dare to bet that he had guessed Zheng Zheng and Xie Miao's ideas correctly, nor did he dare to bet on whether his ideas were correct, so he had to let another person open the door.

This Xiao Wu is one of Xu San's subordinates, and he has been running with him for many years, and he can be regarded as one of Xu San's henchmen, so he will only be brought with him when Xu San comes to do this this time. To be honest, the relationship between the two is good, and Xu San doesn't want him to take risks, but now that the future is unknown, he can only let Xiao Wu come to the thunder.

"Hey, this is easy. Xiao Wu didn't think much about it, walked to the stone wall and grabbed the handle of the "key", and pulled the key out of the keyhole with a little force in his hand.

Thundered......

At the moment when Xiao Wu pulled out the key, a sound like muffled thunder came from behind the stone wall. Xu San subconsciously took a step back, his eyes looking around, wanting to find out what kind of reaction this series of sounds had caused.

The sound of muffled thunder faded away, but nothing changed in the cave. Just when Xu San was suspicious, a loud "boom" sounded in the cave.

Horizontal in front of everyone for a long time, blocking the stone wall that everyone could not go further, guarding the gate of the Xie family's treasure cave, opened in response!

The stone wall is divided into a one-meter-wide and narrow hole with the "keyhole" as the center line, and the hole is dark and misty, and I don't know what is going on inside.

Xu San saw that the stone wall was opened, and he was ecstatic: the Xie family's treasure cave, which he had been thinking about for a long time, was finally opened!

"Hey, boss, it's done. ”

Xiao Wu turned around and smiled at Xu San, bent down as he spoke, and put the "key" on the ground. The weight of this set of "keys" is not light, and it is not easy to handle, and it is really tiring to hold it for a long time.

After putting down the "key", Xiao Wu slowly straightened his waist and felt his hand in his trouser pocket, probably wanting to smoke a cigarette.

Xu San, who was facing the cave after the stone wall was opened, was about to laugh, but suddenly saw that something the size of a sea bowl seemed to fly out of the black stone cave, and Xiao Wu, who was facing the cave with his back, didn't know about it, and was about to stand up straight!

"Little Five!" In a hurry, Xu San hurriedly opened his mouth and shouted!

Xiao Wu subconsciously stood up straight and looked at Xu San: "What's ......?"

Before the word "what" could be spoken, a muffled and crispy sound sounded as if it was breaking a watermelon. Xiao Wu, who was facing Xu San, had a stiff expression on his face, although he still maintained the shape of his mouth, but he couldn't say anything.

With a "poof", Xiao Wu fell straight to the ground.

Through the light of the searchlight, Xu San saw that the back of Xiao Wu's head had sunken a large area, and the red and white ones were all flowing "coo-dong", and he saw that he was dead and transparent.

This shocking change only happened in an instant, and before everyone in the field could react, Xiao Wu had already fallen to the ground. Xu San, the only one who saw that something was about to attack Xiao Wu, reminded him, but Xiao Wu also subconsciously stood up straight because of the sentence he reminded, so Xu San's reminder indirectly harmed Xiao Wu's life.

"Hula...... Hula ......"

A black ball that looked like a pendulum in an old-fashioned wall clock swung around inside and outside the cave with the stone wall open, and it was obviously the murder weapon that killed Xiao Wu with one blow.

The ball swung over Zheng Zheng's head, dripping a few drops of blood that was still hot on Zheng Zheng's face.
