As the entrance to the secret passage was opened, a stream of filthy air immediately rushed out from the depths of the secret passage.
In the blink of an eye, this wave of filthy air rushed to the ground and was blown away by the wind.
Upon noticing this situation, Xiao Ran immediately waved his hand back to stop others who were trying to approach the tomb.
"Samuel, Jack, please stay away from this tomb to avoid any accidents."
"The secret passages and chambers under the tomb have been closed for too long, and a lot of dirty air has accumulated."
"When the dirty air is discharged, it won't be too late for you to come over and check the situation."
Upon hearing this, Samuel and Jack immediately stopped and did not continue to move forward.
The other people who tried to come forward to check the situation also stopped and looked here curiously.
Xiao Ran looked at the newly opened hole on the back wall of the tomb, and then said to his two men:
"You continue to expand the hole, but don't enter this tunnel. No one knows whether there is danger inside."
"One more thing, when taking out the red bricks from the wall, you must have a steady hand. Don't let the red bricks fall into the corridor, which may trigger the mechanism."
The two guys working at the bottom of the tomb nodded immediately.
"Understood, Sean, we will be careful."
With that said, they continued to demolish and expand the entrance to the corridor.
The bricks they removed from the walls were hoisted to the ground and piled on the grass next to them.
After instructing his two men, Xiao Ran immediately turned to look at Professor Baker.
"Beck, let's go over and take a look at what's inside the coffin. Maybe we'll find something surprising."
"Okay, Sean."
Professor Baker nodded in response.
Then, they left the entrance of the tomb and turned towards the oak coffin.
Not only them, Samuel and Jack also followed.
When they came closer, Professor Adrian immediately began to introduce the situation.
"Gentlemen, this oak coffin contains a corpse that has lost its left leg."
"Judging from the remaining linens in the coffin, as well as some copper buttons and crosses, etc."
"The body is indeed that of an American militiaman who was supposedly killed at the famous Battle of Bunker Hill."
"In addition to these things, there is a dagger in the coffin with the name of the militiaman engraved on it."
"The name on the dagger is consistent with the name on the tombstone. The British colonists paid great attention to details."
While Adrian was introducing the situation, Xiao Ran and the others had walked to the coffin and looked up into the coffin.
In this coffin lies a skeleton of white bones, but without a left leg.
There was a rusty cross placed on the chest of the corpse. The cowhide rope tied to the cross had already completely rotted.
On the remains of the already tattered linen coat on the corpse, there were still a few rusty copper buttons.
Some buttons had fallen off the clothes and fell onto the coffin board along the gaps between the bones of the corpse.
On the right side of the waist of the corpse, there was a rusty dagger and some other things.
Through these things, it can basically be determined.
The skeleton was indeed that of an American militiaman, and was likely killed at the Battle of Bunker Hill.
To Xiao Ran, the contents in the coffin were not of much interest. He had already seen them clearly through perspective.
But for Professor Baker and Professor Samuel, this coffin is a small treasure.
Without exception, the history professors at Yale and Harvard all had their eyes shining with excitement.
After seeing clearly the situation in the coffin, Xiao Ran immediately said:
"Gentlemen, please study this oak coffin and its contents slowly. I'm going to the tomb."
After saying that, he left here and walked towards the tomb.
Samuel walked up to Professor Baker and whispered in a consultative tone:
"Baker, can you also let us participate in the research of this treasure?"
"We are not pursuing dominance, we just want to understand the relevant situation."
Professor Baker answered very simply, shaking his head and rejecting the other party.
"I'm very sorry, Samuel. Our cooperation with Sean is exclusive and we do not accept any third party to join us, including Harvard."
After hearing this, several professors at Harvard felt their teeth itching, but there was nothing they could do.
There is no way, who let others discover this treasure? I can only look at it with greed!
Xiao Ran just smiled and said nothing more.
He had no intention of getting involved in the dispute between Harvard and Yale.
For him, both Harvard and Yale are partners he can use and cooperate with, and there is no need to offend either party.
In particular, he has long been coveted for the large number of Chinese antiques and artworks and various rare ancient books collected in the Harvard University Museum and Library.
As long as there is a chance in the future, he will definitely find a way to exchange those treasures and make them his own.
In three or two steps, he had reached the entrance of the tomb and looked at the bottom of the tomb again.
At this time, the entrance to the secret passage at the bottom of the tomb has become larger.
Standing above the tomb, you can see the steps in the secret passage.
On the steps made of red bricks, there was a layer of dust and patches of pale green moss, which looked slippery.
This situation is normal and not surprising.
You know, this is Boston by the sea, and underground in the Boston Common, the humidity is naturally very high.
In order to expel the dirty air deep in the secret passages and chambers as quickly as possible, a powerful ventilation fan was set up at the bottom of the tomb, which was rapidly replacing the dirty air underground.
Instead, there is fresh air from the outside world.
After a while, the air in this secret space deep underground has been completely replaced, and there is no threat anymore.
In a moment, a hole about 60 centimeters wide appeared at the bottom of the tomb.
Seeing that the cave entrance was about the same size and that he could enter and exit smoothly, Xiao Ran called his employees to stop.
"Okay, guys, the hole is as big as it needs to be."
"The space at the bottom of the tomb is limited, so we need to leave some places to stay and place things."
"Clean the hole, then come up and prepare for the next step."
Upon hearing this, the two guys working at the bottom of the tomb immediately stopped demolishing it.
"Okay Sean, we'll be right up"
With that said, the two guys packed up the newly removed bricks and then climbed up the ladder.
At this moment, Jack, who returned to the entrance of the tomb, couldn't wait to ask:
"Sean, are you going to enter this underground secret passage and explore the secret room deep underground?"
"If possible, I would also like to enter this underground tunnel and see with my own eyes what secrets are hidden here?"
Xiao Ran turned to look at the other party, and then shook his head.
"Not so fast, Jack, we still have some preparation work, we have to do it step by step!"
"Only after preliminary investigation and confirmation that this corridor and the secret room underground are safe, can we enter the corridor and explore."
"For example, it is necessary to determine whether the structure of the corridor and the secret room is strong, whether there is water accumulation, whether there are fatal traps, etc."
"After we finish these tasks and make sure it's safe, it's not impossible to take you into the underground secret room to see what's going on!"
Before he finished speaking, Jack and the others were all amazed.
"Wow! You are indeed the top treasure hunting company, you are so thoughtful!"
"It seems that everyone has to wait a little longer to know what secrets or treasures are hidden deep in the land beneath our feet."
Xiao Ran nodded slightly, and then began to plan the next move.
He called a few of his employees over and started assigning tasks to these guys.
"Guys, you first use a small drone to fly this underground tunnel to check the situation in the tunnel."
"At the same time, small drones are used to carry some lighting sticks into the corridor to illuminate the corridor for observation."
"Next, we need to use the robot to do some safety tests to determine whether there are any traps in the corridors and secret rooms."
"In addition, we must also determine whether the structure inside the corridor and the secret room is safe, whether there is water accumulation, etc., and deal with it one by one..."
While he was assigning tasks, everyone else on the scene was secretly amazed.
Especially the three professors from Harvard University, the more they listened, the more frightened they became, and the more they listened, the less confident they became.
It wasn't until this moment that they truly realized it.
Xiao Ran and the others are so professional and capable.
They were becoming increasingly pessimistic about the game of discovery that had begun.
If this situation continues, Harvard University has no hope of winning!
In the blink of an eye, Xiao Ran had completed the task.
After receiving the mission, several exploration team members immediately took action.
They walked to the place where the equipment was placed, took out the exploration equipment they needed one by one, and started setting it up.
Soon, a small drone with a searchlight and a high-definition camera took off.
Then he slowly landed at the bottom of the tomb and flew into the newly opened entrance to the secret passage.
In addition to the high-definition camera and searchlight, there are five or six fluorescent lighting rods that are folded and lit under the belly of this small drone.
As the small drone flew into the entrance of the secret passage, the situation inside the corridor was immediately displayed on the monitoring screen.
On the grass next to the tomb, a large-screen TV had been set up. The equipment had just been shipped from the Ritz-Carlton Hotel.
Xiao Ran and the others stood in front of the TV, watching the real-time exploration scene on the TV screen with great interest.
As soon as it flew into the underground tunnel, under the control of the drone pilot, the small drone immediately released a lighted fluorescent lighting stick.
The fluorescent lighting rod immediately fell down and landed on the steps in the corridor. Then it rolled down two steps and stopped on the third step.
At the same time, the searchlights carried by small drones also brought light to this underground tunnel that had been closed for more than 200 years.
The same situation as previously detected using deep ground-penetrating radar.
This underground tunnel is built very regularly and can be called an underground building.
Both the steps and the walls on both sides are made of red bricks and granite, which looks quite solid.
The vault above the corridor is built with granite strips, and everything is perfectly jointed.
However, this corridor was empty.
There was nothing but dust and moss everywhere.
In the first half of the corridor, there are only two round holes for torches, located on the walls on both sides.
Even so, the situation in this corridor still shocked everyone.
"Oh my God! It's unimaginable that there is such an underground building deep underground in the Central Cemetery!"
"Obviously, the British colonists must have spent a lot of manpower and material resources to build this underground structure."
"But for more than two hundred years, no one knew about this underground structure. It's incredible!"
Professor Baker said in amazement, his eyes shining with excitement.
Hearing this, everyone else nodded in agreement.
At the same time, everyone is looking forward to the secrets or treasures hidden in this underground building.
While he was talking, the small drone deep in the corridor had flown to the corner of the corridor.
The next moment, the surveillance picture suddenly changed.
An even more shocking scene suddenly appeared on the surveillance screen.
