Chapter 1518： Dark secret road

Seeing that it was about to dig to the iron gate buried in the soil, Ye Tian suddenly stopped digging and stepped up from the pit.

Seeing his actions, Anderson asked puzzledly:

"Steven, you're about to dig into the iron gate below. Why do you stop? Is there something wrong?"

Ye Tian looked at the kid, then smiled and gave the answer.

"Of course there is a reason why I will stop digging. No one knows the situation in the secret room deep underground. Whether there is a ventilation system is yet to be known.

If there is no ventilation system, it means that the air inside has not circulated for more than two hundred years. It must be dirty and even toxic.

To be safe, we must now wear gas masks before we can dig out the last layer of soil and then open the iron gate under the soil."

Suddenly, Anderson nodded hurriedly, expressing his approval.

Immediately afterwards, the two picked up a gas mask each and put it on their faces, and Ye Tian also put on gloves.

After taking protection, Ye Tian jumped into the pit again and began to dig.

It took less than a minute, and the last bit of dirt was dug out, and the iron gate that was originally covered with dirt was immediately exposed!

It was a rectangular iron door about one meter two to three meters long and about one meter wide. It looked very thick and solid. There was a huge lock hanging on it. Both the iron door and the padlock were rusty.

The iron gate is surrounded by a circle of granite, the material of which is the same as the two granite bars just pried apart, obviously from the same place of origin.

The first time he saw this iron gate, Anderson celebrated with joy, but it was a pity that he couldn't talk or cheer. It was a bit of a pity!

The same is true for Ye Tian. Although he has seen all of this before using perspective many times, seeing this rusty iron gate again at this time still made him excited!

After celebrating silently, Ye Tian began to clean the dirt around the iron gate.

In a blink of an eye, the cleanup work has been completed, and this iron gate that has been closed for more than two hundred years can be opened, and the treasure hidden in the underground chamber can be seen again!

Ye Tian jumped out of the pit again, put the folding engineer shovel in his hand on the floor, then took out the hydraulic clamp from his handbag, and then jumped into the pit again.

"Snapped!"

With a crisp sound, the rusty padlock on the iron door was directly cut by the hydraulic pliers, without any effort!

However, Ye Tian did not immediately pull up the iron gate to find out!

He waved his hand at Anderson and told him to withdraw a little bit to avoid any accidents.

This is a secret room door that has been closed for more than two hundred years. God knows if there is any mechanism behind the door that hurts the moment the iron door is opened.

Of course, Ye Tian knew better than anyone about whether there was any mechanism behind the iron gate, but some performances were still indispensable.

Anderson took a few steps back according to the instructions, stood three meters away, stretched his neck forward, fixed his eyes on the iron gate and the movements of Ye Tian, ​​full of anticipation, and a little worried.

Ye Tian also changed his position. He came to the side of the iron gate and stood still, and then exerted his force to pull up the heavy iron gate that had been closed for more than two hundred years.

That iron gate was almost completely rusted to death, even Ye Tian took a little effort to pull it.

"Crack!"

There was a toothless metal rubbing sound, which sounded uncomfortable.

In Ye Tian's hands, the iron gate was pulled up a little bit, very slowly.

This was done intentionally by Ye Tian, ​​and it was done for Anderson and for others to see. If there is any mechanism in the secret path, he will immediately let go and instantly close the iron gate to ensure the safety of the people standing outside the gate.

No bullets, no crossbow arrows, no poisonous smoke, monsters, etc., nothing!

Some are just a dark hole, a string of steps that are covered with moss and go straight to the depths of the ground, the darker and darker they go down, until nothing can be seen!

"boom!"

Ye Tian opened the iron gate completely, leaning on the granite next to the pit, and making a loud noise.

After opening the iron gate, he didn't immediately look into the dark tunnel, but paused for four or five seconds before looking at the dark secret tunnel that led to the depths of the earth, although he had already understood the situation inside!

The result can be imagined, except for the steps covered with moss and the bronze candlesticks from the early 18th century on the walls of the underpass, nothing else can be seen!

An arc-shaped curve at the end of the dark road blocked Ye Tian's line of sight. He didn't know whether there was a mechanism behind that arc-shaped curve!

After scanning the situation in the underpass, Ye Tian stepped across the excavation pit, came to the handbag, took out the glare flashlight and air detector from it, and returned to the underpass entrance again!

At the same time, he also waved his hand to let Anderson come over. The entrance of the underpass was safe and there was no mechanism.

Seeing his gesture, Anderson rushed over immediately, looking like he couldn't wait.

When he came to the entrance of the underpass, this guy immediately looked inside the underpass with an expression of excitement.

At this time, he wished to have two wings and flew directly into the secret tunnel, into the secret room deep underground, to see what secrets were hidden inside, whether it was a valuable treasure!

The lights came on, and this dark secret passage was closed for more than two hundred years, and for the first time there was light!

Ye Tian turned on the bright flashlight and shone into this dark tunnel that slanted downward, and the situation in the dark tunnel was immediately revealed!

Everything was the same as he had seen before, there was no abnormality, and the secret tunnel was very quiet, revealing a mysterious atmosphere.

After scanning the situation in the dark tunnel, Ye Tian handed the bright flashlight in his hand to Anderson, and asked Anderson to hold the lighting.

He himself took the air detector placed next to him, hung it into the dark tunnel, and began to detect the air quality in the dark tunnel to see if it was dangerous!

The test results were quickly released. Except for the slightly higher humidity, the air quality in the dark tunnel is not much different from the outside world, and there is no toxic gas.

This is undoubtedly good news. The feeling of wearing a gas mask is not as good as that. Of course it is best to not wear it.

Ye Tian looked at the air test results again, and after confirming that the air quality in the secret tunnel was good and there was no danger, he immediately took off the gas mask and placed it on the floor next to it.

Seeing his movements, Anderson took off the gas mask and put it aside, and let out a breath.

As soon as he took off the gas mask, this guy couldn't wait to say:

"It seems that the air in the secret tunnel is not bad. This is really good news. It doesn't feel much to wear a gas mask, especially when you can't speak, it's too uncomfortable to hold back!"

Ye Tian nodded lightly, and then continued:

"Obviously, this underpass and the secret room below were equipped with a ventilation system at the beginning of construction, so the air quality is so good, there is almost no difference from the outside world.

According to my inference, the ventilation system of this underpass and the secret room below is likely to be connected to the ventilation system of Notre Dame Cathedral next to it, or directly lead to the Seine River not far away! "

"I think the same is true. This building is very close to Notre Dame Cathedral and used to be an annex of Notre Dame Cathedral. It is normal to share a ventilation system.

Moreover, it is only one or two hundred meters away from the Seine River, and the ventilation system connects to the Seine River. Maybe there is a dense road directly leading to the Seine River, which is used as an escape route!

Can we enter this secret passage and underground secret room? I look forward to seeing the situation in that secret room and see what treasure is hidden there! "

Anderson said with excitement, eager to try, wishing to step into the secret room and discover the treasure immediately.

Ye Tian shook his head gently, and said solemnly:

"Don't worry, Anderson, the specifications of this underpass and the underground chamber are very high. It must have taken a lot of thought and cost when it was built. We must not enter it rashly!

Secret passages and basements like this, in all likelihood, have deadly organs or traps to prevent enemies, treasure hunters, or other people from breaking into secret passages and secret rooms.

Therefore, we must be careful, and we must not rush in without knowing the situation. It is undoubtedly a joke of our own life, which is a very stupid behavior."

Hearing this, Anderson immediately shuddered, and even stepped back half a step, lest he suddenly shot bullets or crossbow arrows in the secret tunnel, and killed himself, then he would lose out!

Seeing his behavior, Ye Tian couldn't help laughing softly.

"There is a Beetle drone in that handbag. Let's use the Beetle drone to explore first. This is the safest way. Even if there are traps in the secret tunnels and secret rooms, it is impossible to do anything with the Beetle drone!

After using the Beetle drone to find out the general situation of the dark tunnels and secret rooms, and basically confirming the safety, let's enter the dark tunnels to fumble forward bit by bit, and completely reveal the secrets hidden deep underground! "

After speaking, Ye Tian stepped out of the dirt pit, came to the handbag in the center of the basement again, took out the beetle drone and control equipment from it, and then returned to the underpass entrance!

Soon, the small beetle drone flew into the underpass, flew straight down along the underpass steps, and began to perform the exploration mission.

The infrared camera it carried immediately fed back the situation in the dark tunnel and displayed it on the control device in Ye Tian's hand.

In just ten seconds, the Beetle drone flew over the curved curve and entered another corridor connected to it.

It was a corridor that was about five or six meters long and inclined downward, about two meters high and one meter two or three meters wide. At the end of the corridor was a wall, hidden in darkness.

Almost at the same time that the Beetle drone entered the tunnel, Ye Tian's face suddenly changed, and he exclaimed.

"I'm going! This is too exaggerated, it's a big deal!"
