Lin Feng stared at the darkness where the pickaxe disappeared and fell into deep shock.

The words "Haozi" said before leaving were definitely from a sincere warning. Whether this pickaxe or the one that Lin Feng and the others were familiar with, Lin Feng could feel that he was really afraid of the weird black box, or even feared.

But Lin Feng is not a reckless person.

Although he had become very interested in the black box at this time, he is different from Pei Yu and he will not have to find out what is going on because of curiosity.

At least he was not going to touch that thing before he was more sure.

This is not cowardice, but reason, and a sense of awe that unknown forces should have.

"It seems that Haotou doesn't want to find it back. Let's tell Pei Yu and the others the truth about this. But Haotou is really a love-like person? The old man is obviously 'dead', so he still told Pei Yu not to touch that dangerous thing."

Lin Feng glanced at the direction where the pickaxe left and shook his head.

"Feng...Brother Feng, what should we do now? Or not?"

At this time, the man who was originally hiding in the distance and his eyes were also leaning forward with his eyes swept away from time to time, as if he was afraid of something.

"Survey, chase you, big-headed ghost, you're a big man. I'm afraid when I should be chasing you at first, but when I shouldn't be chasing you, I'll just be soft."

Lin Feng gave the fierce man a blank look and said angrily, "Don't chase after him. Who knows what's weird about the downstream of the shallows? And even if you chase him, it's meaningless. Go back."

After saying this, Lin Feng walked up the shallow without looking back. The man and the glasses looked at each other, then looked at the darkness downstream of the shallow, and they all shuddered, then quickly took a step and followed Lin Feng in the direction.

Then the three of them returned to the camp.

…………

In the afternoon, Pei Yu came back with the guys who were exploring the way.

Lin Feng immediately grabbed Pei Yu and said about the pickaxe.

"What!? The pickaxe has been... dead for a long time?"

Pei Yu, who knew the truth, seemed quite surprised. After all, no matter who knew that the person who stayed by him was actually the one who killed his companions, he would feel very scary.

"Okay, I don't think it's important to me if he is still a pickaxe. But I think it's necessary to pay attention to the advice he gave us."

Lin Feng changed his tone and his expression became serious. "I think I should not touch that place first. After all, no matter whether the pickaxe is real or not, he must know what it is, so his words are very authentic."

Pei Yu was silent for a while, as if she was not willing to give up a big secret, but Lin Feng had to think carefully about Lin Feng's words.

In the end, she nodded and agreed not to care about the black box for now. After all, they had more important goals for this trip.

Nothing is important to crack the "password".

This matter seemed to be over, and the depressing atmosphere in the camp quickly disappeared because of this incident, and everyone quickly returned to their roles.

After dinner in the evening, Pei Yu pulled Lin Feng back to the tent first, and then began to tell Lin Feng about his situation when he went to explore the way in the morning.

The route is generally not complicated. As long as you cross a shallower place upstream of the underground river, you can see many artificial traces left by the Qin Dynasty coolies here.

Perhaps it was to transport something out of the ancient city, and there was a road paved with stone bricks on the other side of the darkness, which should be used to pull carts.

This road is just a direction guide. As long as you walk along the stone brick road, you can quickly reach the ancient city.

There are so many main situations about the route. The two of them went down to discuss some questions about how to carry out search work and whether they would encounter any dangers in the process.

It was not until late at night that the two of them finished their conversation and went to bed.

No words all night.

Early the next morning, when Lin Feng opened his eyes in a daze, the camp outside was already busy. All the guys were busy packing their equipment and preparing for the next trip to explore.

After experiencing this messy team, the people in the team came and went, plus the two vanguard team members left before, now, including everyone in Lin Feng and his team, there are only eight people left in total.

Although it feels a little tight, if you just explore it simply, the problem should not be big.

Of course, the premise is not to encounter any trouble...

The team quickly packed their luggage and headed towards the underground entrance. Since they had already checked the route the day before, the team did not delay any delay on the road and prepared to go directly to the ancient city in one breath.

After crossing the underground river, Lin Feng's underground space became larger and larger, and it had changed from the space that could accommodate the next three or four floors of small buildings to a huge hole in the basketball stadium that could be placed in. Moreover, the trend of increasing size is still rising.

Lin Feng had no doubt that he would go further, and the underground space would be able to reach the next city that could be placed.

The group of people, about three kilometers away from the bank of the dark river, finally arrived at the legendary stone brick road. This road is twenty meters wide. Even the commonly used trucks can accommodate 4 vehicles driving side by side!

"I'll go, how many things did Lao Ying move out from here? I said, are there any trouble when we go in now?"

When Lin Feng saw this road, he couldn't help but slap his eyebrows.

Indeed, what Pei Yu guessed at the beginning was that due to various technical reasons more than two thousand years ago, even if the First Emperor discovered this place, he did not have the ability to explore in all aspects, or even take away all the useful things.

But now the appearance of the stone brick road under your feet, which is comparable to the two-way four-lane high road, made Lin Feng begin to doubt Pei Yu's inference.

Moreover, along the way of this road, they found many abandoned tools, wheels, and a complete four-wheeler truck!

This is all evidence that large-scale artificial activities have been carried out here.

"After a lot of technology thousands of years ago, it is impossible to achieve nothing by relying solely on manpower. There must be some important secrets in this ancient city, otherwise the Qin people would not have chosen to block the entrance."

Although Pei Yu's words make some sense, Lin Feng sounds like self-comfort.

But since you come, you can rest assured. Before you thoroughly find out the place, you will have no basis for anything you say.

So Lin Feng didn't think much about it, and brought his men and went deeper along the road with Pei Yu.

The next journey, there were no dangers or accidents, and Lin Feng and the others were able to doubt whether they had taken a fake path.

However, as they continued to walk in for about two kilometers, they arrived at the end of the stone brick road.

Of course, they finally saw the mysterious ancient city recorded in the private notes of the historian.
