Chapter 2756: Stone Pillar Zero

In a blink of an eye, nearly an hour passed.
At the golden section point of this basement, which is the origin of the Fibonacci arc drawn by Ye Tian earlier, there was an extra pit about three meters deep.
The stones and soil excavated from this pit were stacked in two basements on both sides of the corridor.
As Ye Tian expected, all around this deep pit, under the floor, are all unusually heavy and strong granite slabs, which firmly support the building above, thus avoiding collapse.
Only this deep pit dug along the origin is filled with a lot of rocks and dirt, which can still be excavated.
In fact, this deep pit looks more like a well at first glance. Although the well head is not large, the more you dig down, the larger the space, and it just happens to be able to unfold.
Seeing this situation, everyone became more excited and full of expectations.
At this time, everyone is very sure that if you continue to dig along this deep pit, it is very likely that you will unearth earth-shattering major secrets or treasures.
"boom!"
Suddenly there was a crisp sound from the pit. It was the sound of an engineer shovel colliding with granite. You have heard it countless times before, and you've long been used to it!
Immediately afterwards, another excited voice came from the pit.
"Steven, I should have dug to the end. There is a granite slab at the bottom of the pit instead of the stone that was dug before. This slab is just above the origin!"
The moment he heard the announcement, there was a burst of excited cheers on the scene.
"Awesome! I finally dug to the end. I don't know what secret is hidden under this stone slab?"
"What exactly is Leonardo hiding here? It's really exciting!"
As everyone cheered and celebrated, Ye Tian had already come to the side of the pit and looked at the bottom of the pit.
as predicted!
Under the illumination of the light, a mottled granite slab appeared at the bottom of the pit, which happened to be located at the golden section. A subordinate working at the bottom of the pit was clearing the soil on the slab.
Seeing this scene, Ye Tian also excitedly waved his fist gently to celebrate, even though he already knew the existence of this slate.
After a short pause, he said to his subordinates working at the bottom of the pit:
"Dennis, after you have cleaned up the soil on the slab, you should come up. Don't try to pry up this slab. No one knows what's under the slab. Maybe there are traps!
After you come up, I will go down to the bottom of the pit to check the situation and make sure that there is no danger. After everyone wears protective equipment, let’s open this stone slab again and see what we can find."
"Ok, Steven, we will be careful"
Dennis responded, and then proceeded to clean up the mud on the slab at the bottom of the pit.
Ye Tian left the pit and told everyone at the scene to put on all the protective clothing that had been prepared, and put on a gas mask, just in case!
At the same time, he also asked Derek and others to turn on two powerful ventilation fans that had been arranged in the corridor to speed up air circulation.
The underside of the granite slab at the bottom of the pit has been closed for more than five hundred years. If the underground space is not connected to the outside air vents, the air must be dirty, even poisonous!
With Da Vinci's wisdom and means, God knows what trap he set up in that underground space, and he has to guard against it.
With Ye Tian's order, everyone at the scene became busy and began to wear protective equipment.
Within a short time, everyone had put on their protective equipment, and Dennis had also cleaned up the dirt on the slab at the bottom of the pit.
Immediately afterwards, Dennis was hung on the ground, and Ye Tian went down to the bottom of the pit himself, pretending to be serious about the situation at the bottom of the pit.
After a while, he said aloud:
"There are no traps here, it seems to be relatively safe, maybe this is not the real entrance, so Da Vinci did not set up any traps.
Of course, this may also be caused by him deliberately. The purpose is to let the intruder relax his vigilance. In this way, the subsequent traps will be even more deadly."
Hearing this, everyone at the scene nodded, and there was no disagreement.
And Ye Tian, ​​who was at the bottom of the pit, checked the situation at the bottom of the pit again, then stood on the wall, then took a crowbar that he brought down, and inserted one end of the crowbar under the stone slab in the center of the pit bottom. .
Immediately afterwards, he violently pressed the other end of the crowbar.
With this action, the square granite slab was immediately pryed up, exposing a gap.
At the same time, a slightly dirty air rushed out from under the stone slab, which quickly escaped, and then was sucked away by two powerful ventilation fans in the corridor!
In addition, there was no abnormal change, neither javelins nor crossbow arrows rushed out, there was no rolling woods, nor did the world collapse!
As Ye Tian said before, there are no traps here and it is very safe.
After prying up the slab about ten centimeters, Ye Tian quickly stretched out his left hand, took a stone placed aside, placed it under the slab, and pulled out the crowbar and threw it aside.
In the next moment, he held the edge of the granite slab with both hands, paused for a while, and then slowly used his force to lift the granite slab little by little!
During this process, every time the granite slab was lifted up a little bit, he would pause for a while, until he was sure that there were no traps or accidents, he would continue to lift the slab!
Fortunately, there were no traps under and around the slate, and no accidents occurred!
"boom"
With a muffled noise, the granite slab was completely lifted by him!
Seeing this scene, everyone staying in the pit above couldn't help taking a breath of air-conditioning.
You know, that granite slab is one meter square and quite heavy, and its weight is less than one hundred kilograms.
Such a heavy and unusual granite slab, the talking room was lifted and lifted easily by one person, can it not make people feel shocked!
Of course, only Giovanni and a few other representatives were shocked!
As for David and the Bishop of Kent, as well as the employees of the brave and fearless exploration of the company, I have seen such scenes many times, and I have long been accustomed to it!
As the granite slab was lifted, a circular hole about seventy or eighty centimeters in diameter suddenly appeared at the bottom of the pit!
Down the hole is a spiral staircase, winding and winding, extending to the depths of the ground.
Ye Tian, ​​standing at the bottom of the pit, and David staying at the edge of the pit, could only see the first section of the spiral staircase. Due to blocked vision, the situation in the deeper part of the staircase is temporarily unknown!
Even so, the appearance of this hole and spiral staircase also caused an exclamation of exclamation at the scene.
"God! There is really an unknown underground space here, it's incredible!"
"No matter what secrets or treasures are hidden in this underground space, the discovery of this secret passage alone is enough to cause a sensation!"
Just as everyone exclaimed, Ye Tian had already set up the granite slab against the wall, and then came to the hole in the center of the pit and began to check the situation here.
After just one glance, he said with excitement:
"Gentlemen, my previous speculation is correct. On the inside of the first step of this secret passage, there is an Arabic numeral 0, which is the starting number of the Fibonacci sequence, which is what I call the origin.
Obviously, the No. 0 stone pillar that was supposed to stand in the corridor was hidden underground by Leonardo da Vinci. This spiral staircase was built around the No. 0 stone pillar, like a python wrapped around the stone pillar!
Another stone pillar engraved with the Arabic numeral 1 is likely to be deeper underground. If you go down this spiral staircase, you should be able to see it. I have to say that this design is really ingenious."
While saying this, Ye Tian also stretched his hand towards the first step of the secret path, but did not touch it.
Following his remarks, there was another exclamation in the corridor above. Everyone was shocked, and everyone became even more excited!
At this time, they wish they could not immediately descend to the bottom of the pit, enter the secret passage built by Leonardo da Vinci more than 500 years ago, and follow the spiral staircase to see what secrets or treasures are hidden deep underground!
In comparison, Ye Tian, ​​who stayed at that secret crossing, was much calmer than them!
After carefully inspecting the situation at the entrance of the secret passage, Ye Tian stood up and let his subordinates pull himself to the ground.
As soon as he settled on the ground, he began to dispatch the next exploration mission.
"Derek, put down two small drones, enter this secret road and explore it, to see how deep the secret road is, where it leads, and what secrets are hidden in the depths of the secret road?
Put a powerful ventilating fan and an air monitor down to check the air quality in the secret tunnel to see if it is toxic, and replace the air in the secret tunnel to prepare for follow-up actions!
When I just lifted the granite slab, there did not seem to be a lot of dirty air overflowing in the secret passage. From this, it can be seen that this underground space must have vents connected to the outside world!
For us ~EbookFREE.me~ this is undoubtedly a good thing, it can reduce a little risk! As for the location of this vent, it is not known for the time being, I guess it may be in the Sforza Castle not far away.
For the sake of safety, we still need to completely replace the air in this underground space before entering the exploration to avoid accidents! "
"Understood, Steven, leave these things to us!"
Derek nodded in response, and then took someone to get the ventilation fan and other equipment.
At the same time, the curator of the Sforza Castle Museum standing aside was stunned.
"How is this possible? Sforza Castle has vents connected to this underground space! Why do we know nothing?"
Hearing this, Ye Tian couldn't help laughing softly.
