"There is evidence. We based it on historical records and combined it with Qin Shihuang's temperament. Some of his buildings liked to use mechanisms and so on. It may be because the craftsmen's skills at that time were very powerful, or maybe there were many of them like you.

He is a special person..."

Professor Huang said neither quickly nor slowly.

"Although the rock wall of the gate looks like a whole, due to the passage of time, some of the gravel on it will inevitably fall off. You can see that there are two concave shallow holes here, which should be where the mechanisms on both sides of the gate are located, and in the middle

There is a gap that is not easy to detect, which should be where the door is closed."

Professor Huang continued to explain.

Upon hearing this, Zhang Han immediately stepped forward to check and found that it was exactly what he said, but the marks were very shallow, and there were many similar ones next to the two recessed holes.

"Because the experience has been too long, and this door has never been opened since it was closed, we can only analyze it based on years of experience."

Although the content of Professor Huang's words was uncertain, his tone was very certain.

Zhang Han looked at Yunsu and found that she nodded slightly towards him, so he said: "Okay, let's try it from here!"

After hearing this, Lin Fusheng was about to ask the people in the team to bring the explosives over and blow open the door...

"Team Lin, don't be so violent...even if I agree, Professor Huang won't..."

Zhang Han's mouth twitched and he said.

If explosives were really used to blow it up, the door would probably be blown open, but the damage caused cannot be measured in terms of money. After all, they are not tomb robbers...

"If it doesn't explode, even if you guys are born with supernatural powers, you probably won't be able to push them away..."

Lin Fusheng looked at the thick rock wall. He estimated that the gate was at least one meter thick, and he didn't know how high it was. Who could push it open with such weight...

"Didn't Professor Huang just say that this gate should be controlled by a mechanism? That's exactly what I think."

While they were talking, Zhang Han carefully stroked the rock formation.

"Xiaohan, is there any way?"

Yunsu stepped forward and asked.

"Well, Sister Yun, the words I got in the Tower of Merit are exactly about the principles of agency ambush and how to crack it. As the saying goes, one reason is the same, and all principles are the same. Even if you don't have the energy to support it, as long as you find out the other

Where the center is, it can be cracked."

Zhang Han explained.

Immediately afterwards, he stopped talking nonsense and compared them one by one according to the content in the Dunzi Pian. If there were similarities, then he could give it a try.

Half an hour later, Zhang Han touched the rock wall all over, and the smile appeared on his face again. At this time, he already knew it in his heart.

"Crazy battle, Da Zhuang, you stand on one side, and then expand the hole in front of you. I guess the center of the mechanism is here. After all, the mechanism of the gate is not very sophisticated. This is just the first hurdle..."

Zhang Han finally spoke.

"good!"

Both of them have been waiting for a long time, and now it is finally their turn to play, and they both feel a little impatient in their hearts.

"Be careful, I'm worried there will be arrows or something like that."

Although the chance of this is very small, Zhang Han still wants to remind you to be careful when sailing the ship of ten thousand years.

The two nodded, and then each came to the depression. The depression there was only the size of a fist, very shallow. If Professor Huang hadn't mentioned it, it would be difficult to think that it was the mechanism of the gate.

Since they couldn't use magic, the two of them could only rely on physical strength to dig. They took two engineering shovels from the team, and then carefully began to clean up the surrounding gravel.

If it were the other two people, it would definitely not be as easy as them, because these rock walls are very hard, and it is difficult to pry without a lot of strength.

After a while, the two men dug a hole the size of a fist to the size of a washbasin.

"Dig in there."

Zhang Han saw that the two men only expanded the hole without digging deeply, so he spoke.

After hearing this, the two men immediately swung the engineering shovel and dug deep. As the saying goes, skilled people are bold. They relied on their physical strength and regardless of the danger, they dug the hole to a depth of more than 20 centimeters in a few clicks.

.

Suddenly, there was a sound of metal collision, which shocked everyone present, and then they fell silent instantly.

"I found something!"

Kuangzhan said in surprise.

At the same time, there was a sound of metal collision from Da Zhuang's side, and it seemed that the bottom had been dug.

"First clean up the area around the hole to see what it is."

Zhang Han breathed a sigh of relief, knowing that the entrance to the ancient tomb was here.

The two nodded, swung the engineering shovels and started working. After a while, the originally fist-sized depression turned into a large hole more than one meter wide and half a meter deep.

The things inside also revealed their original appearance. Two iron chains as thick as arms were lying quietly inside. Although they had experienced the baptism of time, there didn't seem to be much rust on them.

"Is this Xuan Tie?"

Lin Fusheng blurted out in shock.

"Xuantie?"

Zhang Han didn't know what it was, so he asked.

"It shouldn't be wrong. Black iron is also a type of iron, but it is extremely hard and difficult to rust. Their weight is much heavier than ordinary iron. Some of the best weapons in ancient times were made of them.

, both sharp and well preserved.”

"I didn't expect that this place would be used to make iron chains. Only the emperor can do this kind of craftsmanship..."

After Lin Fusheng finished his analysis, he sighed with emotion.

"Let's not talk about this for now, Xiaohan, what should we do next?"

Yunsu saw that the iron chains on both sides were clearly visible, so there must be some way to touch them.

"It's very simple. Just pull the chains on both sides at the same time. When they are pulled to a certain extent, the door will open automatically..."
