"Bang ——!"

Suddenly there was a crunch at the bottom of the pit, which was the sound of metal hitting the rock.

Immediately after, Derek's excited voice came from the bottom of the pit.

"Steven, we dug up a granite staircase, and it's half smashed, and the knock marks on it are very obvious."

Hearing this, Ye Tian and Bishop Kent immediately stepped forward, came to the edge of the pit, and looked at the bottom of the pit that had been dug to a depth of more than three meters.

At this time, Derek and another company employee were standing at the bottom of the pit, covered in mud and looking somewhat embarrassed.

However, their faces, hidden under protective masks, bloom with bright smiles.

Seeing Ye Tian appear at the mouth of the pit, Derek immediately scraped the ground with the sapper shovel in his hand, pointed to the exposed half of the steps on the ground and said:

"Steven, this is it, this is the remnant of a half-granite staircase, although it has long been smashed, but it is still recognizable"

Ye Tian condescendingly looked at the half of the steps, and then pretended to be excited and said:

"That's right, it's a half-granite staircase, and it seems that my previous guess was correct, there was originally a secret passage to the depths of the earth, but it was deliberately destroyed and backfilled.

The passage to the upper part of the basement was deliberately smashed and backfilled with gravel so that no one could see it.

I don't know who smashed and backfilled this secret passage, but I have to admit that this is a very clever approach, and even if someone pried up these granite floors in the basement, it would not be possible to find this secret passage.

Even if the Germans rebuilt the Temple Palace, in order to maintain the original appearance of the Temple Palace and repair the old one, it would not be possible to dig three or four meters deep underground, and naturally this smashed secret passage would not be discovered.

Judging from the traces of the destruction of this secret passage, it should be no more than a hundred years old, which is the same as my previous prediction, a few decades ago, someone used to manipulate here to try to cover up some secret!"

Hearing this, Derek and the others, who were standing at the bottom of the pit, and the Bishop of Kent and David, who were standing at the edge of the pit, all nodded their heads in unison, and there was no disagreement.

After a pause, Ye Tian continued:

"Derek, you first scan the bottom of the pit with a pulsed metal detector to see if you can scan a metal signal to prevent the existence of traps and make sure it's safe before digging"

"Okay, Steven"

Derek nodded in response, then lowered his sapper shovel.

Another company employee, who was also at the bottom of the pit, stopped digging for the time being.

Immediately afterwards, Ye Tian asked people to put down a pulsed metal detector and put it at the bottom of the pit.

After getting the metal detector, Derek and the two of them immediately began to probe, scanning the bottom of the pit with the detector's probe.

At that moment, Cole's voice suddenly came through the wireless invisible headphones.

"Steven, the Germans in the halls of the Temple Palace have once again approached us, and have pressed to enter the basement to oversee and participate in the ongoing explorations, all of them very eager.

What do you think? Do you let these Germans into the basement, or do you keep them in the halls of the Temple Palace? If you continue to block them and don't give them a chance to participate, maybe it will lead to conflicts!"

Hearing the report, Ye Tian did not respond immediately, but thought about it.

After a little groaning, he whispered:

"It's impossible for us to hide our actions in this basement from the Germans on the ground, the sound of the drilling rig and the sand and dirt that keeps coming out of the basement.

You're right, in this case, if you don't give those Germans any chance to participate in exploration and supervision, those Germans will probably be mad, this is Berlin, Germany after all.

We can give in a little bit, Cole, and you can tell the Germans that they can send four men down to participate in and oversee the ongoing exploration, and we can only provide four hazmat suits.

As for which four people will come down, it's up to them to decide, and when they get here, I can give them a general introduction, and then they'll leave this basement and wait outside the door for news."

"Okay, Steven, I'll tell the Germans what you mean."

Cole answered, and ended the call.

As soon as he finished speaking, Derek's voice came up from the bottom of the pit again.

"Steven, we haven't scanned any metal signals, and apparently there's no metal buried here, and there should be no traps."

Hearing this, Ye Tian immediately looked at the bottom of the pit, and then said in a deep voice:

"You put the Pulse Metal Detector aside, and then dig down the course of that granite slab, scanning the ground with the metal detector for each step.

Although no metal signal was detected at the bottom of the pit, no one could keep it in order, and there were no other traps on these steps, some of which had no metal objects, but they were just as deadly, such as flap traps.

For the sake of safety, when digging down, you must be extremely cautious, watch your step, it doesn't matter if you are slow, safety is the first thing, you tie the safety rope around your waist, just in case"

"Understood, Steven, we'll be careful"

Derek at the bottom of the pit nodded, and another company employee nodded.

Next, Ye Tian asked his staff to put two safety ropes to the bottom of the pit, and Derek and the others immediately tied the safety ropes around their waists.

The end of the two safety ropes is tied to two pillars in the corridor outside the basement door, which is very strong.

After strapping the safety rope, Derek and the others picked up the sapper shovel again and began to dig down.

After digging a few times, they made a new discovery.

"Steven, this is a sloping down staircase, the steps below are all granite texture, basically intact, but the vault above the steps and the walls on both sides have been deliberately removed.

Looking at the direction of this staircase, it should lead to the side of the Spree River, whether there is a bend in the middle, then I don't know, in the depths of this granite staircase, there must be a great secret."

At the same time as Derek introduced, Ye Tian, who was standing at the edge of the pit, had already seen another granite step exposed at the bottom of the pit.

Compared to the previous half of the steps, the second step is more intact, with only one corner missing.

Ye Tian looked at the steps that appeared at the bottom of the pit, then nodded with a chuckle and said:

"You're right, the person or fellows who smashed and backfilled this secret passage are trying to erase it so much, and the secret they want to hide must be no small thing.

I have a hunch that if you dig a little further down, you will see a complete secret passage, and that secret passage is likely to be sealed, and the thing that seals the secret passage may be a large stone slab.

Because of this, the pulsed metal detector can't scan any metal signals, and of course, there is another possibility, the secret passage is so deep that it exceeds the range of the metal detector."

Next, Derek and the others continued to wave their arms at the bottom of the pit and dig down the steps, while Ye Tian and the others stood at the edge of the pit mouth, condescending to look at the situation at the bottom of the pit.

As they spoke, Derek dug up another step, and several large buckets of sand were hoisted to the ground before falling to another basement outside.

At this moment, under the leadership of Cole, four Germans in full protective suits rushed into the basement, everyone was very excited and full of anticipation.

The four Germans were the head of the Temple Palace, a deputy minister from the German Ministry of Culture, the director of the Berlin Museum and a prominent archaeologist.

Seeing them come in, Ye Tian and Bishop Kent immediately greeted them, introduced the general situation to these Germans, and then brought them to the edge of the pit.

When these Germans saw the granite steps at the bottom of the pit, their eyes lit up one by one, as if they had discovered a door to a new world.
