It became a national treasure after being bound to the treasure hunting system.

Qiu Yunzheng didn't rush in, but observed at the entrance first, and waited until the system sent her the second half of the map before she was ready to act.

However, Qiu Yunzheng didn't let Gu Hanfeng and them go, but planned to try it himself first, because this mechanism is quite simple.

According to the method given by the system, as long as a person weighing no more than a hundred walks over and closes the mechanism.

"You wait for me here, there is a mechanism in the passage here, it is an ordinary gravity mechanism, except for me, your weight does not match, and walking over may trigger the mechanism.

Everyone didn't say anything when they heard this, they just stared at Qiu Yunzheng very seriously, to prevent any accidents from happening to Qiuyun Zheng, and they could rescue them in time.

And the current Qiuyun Zheng is not the same as before, after being strengthened by the enhancement liquid, under the training of Gu Hanfeng's high-intensity training plan, and now he has awakened the water ability.

Except for Gu Hanfeng, everyone else present was not her opponent, and this was also because the others had not used the enhancement liquid, but it was almost over.

Although the matter of the ability is still semi-secret, the enhancement liquid has been disclosed internally, and the enhancement liquid has been successfully developed.

It is estimated that when they return to the capital, these people will all have to use the enhancement liquid, and if they compare with Qiuyun Zheng at that time, the winning rate will only be about five or five.

"Wait, put this on first.

Qiu Yunzheng was about to walk over directly, but was stopped by Gu Hanfeng, who was observing the surrounding situation.

Of course, Gu Hanfeng didn't think about stopping Qiu Yunzheng from taking risks, and this mechanism was not a risk, he just found that the mechanisms that hurt people were all on the wall.

However, this floor seems to be movable, if Gu Hanfeng didn't guess wrong, it might fall short, and that point might be a knife mountain that can hurt people's lives.

Gu Hanfeng took a bundle of safety ropes, walked in front of Qiu Yunzheng, and carefully put the safety rope on Qiu Yunzheng.

"It's okay, go now, this floor should be movable, and if there's any danger, I'll be able to pull you directly."

Gu Hanfeng tugged a few times again, and after making sure that the rope was safe and strong enough, he explained to Qiu Yunzheng who was looking at him in surprise.

"Well, okay, thank you Coach Gu.

Qiu Yunzheng nodded quickly when she heard this, she said, she was worried about herself, but in her heart, it was inevitable that she was a little warm.

Qiu Yunzheng has her own system, and she doesn't think there is any danger in this mechanism, even if there is any danger, this system can't watch herself die.

But people don't know about it, and Gu Hanfeng doesn't know either, I have to say that although Gu Hanfeng is usually a bit like a teaching director and is also very cruel, he is still a good person.

Qiu Yunzheng followed the safest route given by the system, and slowly moved to a stone sculpture on the far left of the middle room step by brick.

Carefully reaching out to avoid the sharp teeth of the stone carving, in the middle of the stone carving's mouth, gently turning the mechanism to the right.

"Boom!"

At this time, the floor of the entire middle room was turned from the original blue brick floor into a large bluestone slab, and Qiu Yunzheng also saw that the mechanism at the bottom was also changing.

After a while, it stopped, and under the prompt of the system scan, Qiu Yunzheng knew that this mechanism was solved.

"It's okay now, come here, and when you dig later, you may have to pay attention to it, and don't touch it here again."

"If this mechanism hadn't been closed just now, there would have been a dense stream of arrows from the walls at both ends as soon as someone walked by. Even if someone dodges, the stone slab at the bottom will disappear in an instant, and then the person will fall into the knife mountain below.

Qiu Yunzheng waited until everyone came over, and then explained to everyone seriously.

This trap is quite dangerous, and after people think they have escaped the trap and relax, the stone slab at the bottom suddenly disappears, and I believe that few people can escape this death trap.

Even if they dodge, they will definitely be injured, and the dense arrows above and the mountain of knives towering at the bottom are all with venom that has existed for a long time.

Even if it's not poisonous, these arrows and knives have been around for so long, and if you get a tetanus infection, or if you get incurable bacteria or something, it will be troublesome.

"Understood.

Gu Hanfeng nodded when he heard this, he didn't say anything more, and his expression didn't change much, but his eyes became more serious.

Gu Hanfeng first walked to Qiu Yunzheng's side and helped her untie the rope first, but at this time, his eyebrows seemed to be wrinkled, and he didn't know what he thought.

But soon it returned to its normal appearance, Gu Hanfeng looked at the mechanism in the mouth of the stone carving, lowered his eyes and thought for a long time.

"Professor, if the mechanism here is destroyed, will it affect the archaeology in the later stage?

Gu Hanfeng turned his head to look at Bai Lishen and asked.

"No, we also have video recording of the whole process, and for safety reasons, we usually destroy the mechanism.

Bai Lishen heard Gu Hanfeng's inquiry, shook his head and explained.

Since this is the case, it will be easy to do, Gu Hanfeng turned around and reached into the mouth of the stone carving, and with a force in his hand, he broke off the mechanism inside, and then used his ability to jam the inside.

The current mechanism is basically useless, unless someone damages the stone carving and exposes the mechanism inside, but even so, you have to find a way to destroy Gu Hanfeng's metal ability.

"That's okay, and you don't have to worry about getting hurt if someone comes in later.

Gu Hanfeng handed the broken machine stone bead to Bai Lishen, Bai Lishen turned off the flashlight in his hand and put it away, and carefully took the stone bead.

Bai Lishen looked at it carefully, and found that it was just an ordinary stone bead, so he packed it in a sealed bag, wrote something on it with a pen, and carefully put it on the ground on the side.

There is still a long way to go, so heavy that it is not convenient to hold, it is good to put it here, and then put it away when it comes out.

"Next, we'll need to go around the corridor on the left to the back, behind the two backrooms, where the real entrance is, and the door here is meant to confuse outsiders.

"If we open the door from here, we'll be attacked again by the mechanism we just closed, and even if we destroy it, it's useless.

Qiu Yunzheng looked at the bright gate in front of him, as well as the overly conspicuous mechanism next to the gate, and explained with a serious face.

The wisdom of the ancients is really quite high, and this has calculated the hearts of the people in their original form, and normal people have closed down when they see this mechanism.
