Under the stunned gaze, Yang Jing used a steel cone taken out of his pocket to pry off a small square stone from the middle of the cross on the top of the tombstone.

Judging from Yang Jing's relaxed spirit and the regular shape of the small square stone, this stone has obviously been "intacted" on this cross, but how could this guy Yang Jing know that the middle of this cross is hollow?

This square stone was pried off from the back of the cross. When he was offering flowers just now, he seemed to have never seen the back of the cross!

The princess was very puzzled. She couldn't figure out how Yang Jing saw the tricks of this cross.

After Yang Jing took out a small rectangular box smaller than a cigarette box from the cross and stuffed the stone back into its original position again, Princess then asked the question excitedly and puzzledly.

Yang Jing shrugged his shoulders and said proudly: "My wife, treasure hunting is mainly based on the word "Seeking". Therefore, it is not so easy to become an excellent treasure hunter. He must have a pair of eyes that can see through all the illusions, a strong enough heart, and a courage that has not changed when the mountain collapses before. This is the most basic condition that an excellent treasure hunter should have. For example, your husband, I... As for you, my dear daughter-in-law, you still have to exercise..."

This was a serious and suspicious person, and Yang Jing was immediately suppressed ruthlessly, and he beaten his pink fist and hugged his head and begged for mercy.

Anyway, there is no one here, so they don’t have to worry about being seen after a little trouble from here.

After making a fuss for a while, the discomfort that Princess felt after they arrived here was completely dispelled. Princess panted and asked, "Yang Jing, how did you find that there was something wrong with that cross?"

"Actually, I didn't find any problem, but I felt that this cross was a little tricky. My wife, as a treasure hunter, I had to make bold guesses and carefully verify it. Intuition is sometimes very important in this industry. Just like when I saw this cross, I felt something was wrong. Then the priest said that this tombstone was made by Martin. Bowman himself made it himself before he died of illness, so the cross was even more suspicious, so I waited for the priest to check it out, and the result really made me discover something unusual."

The princess smiled and gestured to Yang Jing, then urged: "Hurry and see what is hidden in this box."

This box is a metal box made of stainless steel, which is a bit similar to the metal cigarette box from World War II, but it is smaller and thicker than the metal cigarette box. However, this box has been stored in the hollow cave, and the square stone used to block the cave is inlaid with the cave. The gap is filled with a substance similar to glue. Therefore, even if this metal box has been in the cave for more than 60 years, and is made of stainless steel, there is no rust on the surface of the box at all, just like a new one.

There is a lock on the lid of the box, but the lock is not locked, so Yang Jing pulled it open with a slight pull.

After opening the box, the two saw a ball of paper similar to straw paper inside the box. This ball of paper stuffed the box full of it. When Yang Jing took out the ball of paper carefully and spread it out carefully, both of them laughed at the caution they had just now.

Both of them thought there was something written on the ball of paper, but after opening it, they found that the girl was a ball of paper used to fill the box. However, Yang Jing did not throw the paper away, but carefully folded it up, pretended to put it in his pocket, and threw it directly into the storage space.

Sure enough, when the paper was taken out, the things inside the box were revealed.

It is a key, a key made of stainless steel. And judging from the key teeth, the corresponding lock of this key should be a relatively complex lock.

"What key is this?" asked Gege curiously.

Yang Jing shook his head and said, "I don't know either. But being able to be hidden in the cross by Martin Baumann is definitely not an ordinary key."

"Is there anything else in the box? Or is there any prompts for the inner wall of the box?"

Yang Jing picked up the box and looked carefully, shook his head again, "There is only this key and that ball of paper. But it is obvious that the ball of paper is stuffed in to prevent the key from colliding in the box."

"Then what's the use of this key? What do you know where this key is to be used."

Yang Jing patted the back of the princess' hand and said, "Don't worry, don't worry. If you can find such a key, it means that the route we are looking for is correct. As for where this key is used, we still need to slowly find clues. My wife, this is the key left by Martin Bowman. If I guess it is good, if I can find a place that can be opened by this key, the things inside will definitely give us a great harvest."

"Is it a ** treasure?" Princess was excited.

Yang Jing shrugged, "Who knows? Maybe it's the ** treasure, or maybe it's other unknown secret. Anyway, this key is very important and a key. So, the clues we need to query next should be around this key."

As he said that, Yang Jing took out a sturdy string from his pocket, then put the key in, tied it up, and hung the key directly on his neck, "Hehe, this is the safest."

After stuffing the key into the T-shirt, Yang Jing said, "Let's go and find the priest and see what Martin Bowman donated to this church before he died of illness, as well as some things left after his death. Maybe we can find new clues in those things."

Princess nodded in a temptation, "Yes, since this Martin Bowman donated things to the church and was finally buried here, there is this key in that cross. My intuition tells me that Martin Bowman donated things to the church was probably of no intention."

This made Yang Jing laugh, and he gestured to the princess and said, "Wife, you are doing well now and now. Be bold and guess and be careful to verify. You are doing this right. Let's go and see if there are any relevant clues in those things."
