The light above his head disappeared, and there was no sound around him. The moment the marble slabs closed, he seemed to be the only living person in the whole world. Fear spread in his body in that second, becoming stronger and stronger. What he was thinking about now was not how to explore the underground world, but how to get out!

Xia Lei's first thought was to call the members of the Zodiac War Team and let them use explosive devices to explode the two stone slabs on their heads. But after he took out his cell phone, he found that even if the satellite phone had a signal, he began to regret not allowing the members of the Zodiac War Team to come with him. If the members of the Zodiac War Team came with him, they would definitely have a way to get the two stone slabs on their heads and save him. Judging from the current situation, this method obviously doesn't work.

Then, he searched all over the square "hall" under the marble slab. What disappointed him was that there was no mechanism for opening the slab here, and there was nothing else here except the black bones and black rocks.

However, as he was looking for the mechanism, his emotions slowly stabilized.

"In order to understand the secrets of ancient alloy fruit and AE, I did not hesitate to be enemies with the Cia and the Fa organization, and I almost died several times. Compared to those dangers, what is the maze in front of me? Since I have come, I will get a result. I don't believe that Da Vinci has gone through a lot of trouble, just to trap me here." After thinking about this, Xia Lei's heart calmed even more. He held the glow stick into the passage, with the determination not to hit the wall and not look back.

Kick, kick, kick...

The sound of footsteps echoed in the passage, spreading to the distance, and colliding on the black stone walls, giving people the feeling that there are many people walking. In addition, the elements of gloomy, cold, and black are all exuding a terrifying atmosphere everywhere.

Xia Lei did not walk fast and seemed cautious. He had to pay attention to all situations, air, terrain, and even the stone bricks under his feet. He had to observe carefully to avoid accidents.

Fortunately, this underground maze looks like an enclosed space, but the air here is not dull and seems to be flowing. This discovery made him at least a point confirm, that is, he doesn't have to worry about dying here due to lack of oxygen.

The passage soon reached its end, and after a corner, three passages appeared in front, one to the left, one to the right, and one to the right.

There was a mummy lying on the left passage and the entrance to the right. The corpse was well preserved, and the face of the deceased was clearly visible. Both corpses were wearing white robes, coats and leather armor, and the crustals were sold with iron on their chests. There were also weapons next to the corpse, one was a heavy mace and the other was a two-handed axe. Both the mace and the two-handed axe were rusted, and it was obviously an antique that had been around for hundreds of years.

There is no way to find the answer to why these two crusaders appeared here, but Xia Lei knew how they died. The bodies of the two crusaders were covered with crossbow arrows. Some crossbow arrows passed through the body, some crossbow arrows pierced into the chest, and some crossbow arrows pierced into the head, which looked very terrifying. From the lying position of the corpse and the direction of the sluggish arrow shooting, it can be seen that they were all shot out from the channels on the left and right sides. The channels on the left and right sides seemed to be dead ends, with many mechanisms.

Only the passage in the middle seems very clean, without corpses and without sagging. The passage in the middle seems to be the way to live, it is safe.

However, Xia Lei knew that these were all illusions. He picked up the mace next to the corpse on the left passage, then came to the entrance of the passage in the middle, and waved his arm to throw the rusty iron knife into the middle passage.

When the nail hammer flew out, he quickly dodged and hid behind the stone wall.

The mace flew into the middle passage, then fell down, fell on a stone brick on the ground, and then slid forward. The stone brick hit by it obviously sank a little. At that time, a whizzing sound came from the middle passage, and a large piece of slow arrow flew out like a frightened sparrow.

Ding Ding Ding!

Mars flew everywhere, and arrows hit the stone walls and the floor tiles, with amazing momentum and terrifying numbers!

Xia Lei, who was hiding behind the stone wall, was shocked and sweated. If he had chosen to walk the middle passage as soon as he arrived, he might have turned into a human-shaped hedgehog now.

But this is not because he has a strong observation ability, but the map left by Leonardo da Vinci on the canvas of Mona Lisa. This underground space is a maze full of traps of mechanisms, and Leonardo da Vinci's map guides a safe route.

However, even though the whole map was installed in his brain, he knew the correct route, but he still didn't dare to believe Da Vinci rashly, so he did the test just now. He didn't want to die in vain because he believed in a dead person. After all, what if there was a mistake in the map hundreds of years ago?

After the crossbow arrow stopped firing, Xia Lei came to the passage entrance on the right. He picked up the crusaders lying at the entrance of the passage, then raised his arms and threw them into the passage on the right.

Whoosh swish swish swish...

Another locust-like crossbow arrow shot out, and hundreds of crossbow arrows weaved a strangling net in the narrow passage. As long as it was in the passage, not to mention a person, even a sparrow would not want to survive.

After the test, Xia Lei came to the entrance of the passage on the left, which was the correct passage marked by Leonardo da Vinci. But he still did not walk in rashly. He took off the Crusader's helmet and threw it in. After the helmet fell to the ground, it rolled forward jingling, but the passage on the left was calm, with no crossbow arrows flying out, and no other mechanism was triggered.

Xia Lei's left eye jumped slightly, awakening the ability of perspective, and then raised his fluorescent stick and walked in. His left eye's gaze quickly moved forward, reconnaissing the situation ahead like a radar. Three minutes later, he ended the perspective. He did not find any mechanism traps hidden in the stone walls and underground. This passage was indeed a safe passage.

After a distance, the passage on the left also reached the end, and six passage entrances appeared at the end.

There were also several crusaders' bodies lying on a clearing in front of the entrance to the six passages.

These crusaders were not shot by crossbow arrows, but were killed. Some had swords on their bodies, some had their heads rolled aside, and some had their chests split by sharp axes, which was a terrible sight.

Xia Lei's eyes moved to a heraldic shield, and he saw a cross pattern that looked like a pieced together with four arrows. There was also a silly word for "guarding faith and aiding suffering". In that moment, relevant information emerged in his brain.

That is the emblem of the Knights of the Hospital. The Italian language on the heraldic shield is also the motto of the Knights of the Hospital.

The Knights of the Hospital are a very important military force in the Kingdom of Jerusalem. It is known as the three major Knights together with the Teutonic Knights and the Templars. At the heyday of the Knights of the Hospital, it even established a crusade state. Later, the Kingdom of Jerusalem fell, but the Knights of the Hospital still stood firm on the island of Malta and became the last force during the Crusades. In fact, the Knights of the Hospitals also exist until today, but the name has become the Knights of the Malta. It enjoys the status of a permanent observer entity in the United Nations, but it has no territory. Its headquarters is located in the Palace of Malta in Rome, located at No. 6 Condodi Street, Rome. But this is not its territory. The sovereignty of the land belongs to Italy and is leased to the Knights of the Malta, and Italy gives the building diplomatic treatment.

The knights of these hospitals also aroused Xia Lei's thoughts, "I thought the two corpses were deliberately placed there by Da Vinci, which was tempting to enter the dead end. But now it seems that it is not. The knights of these hospitals' knights broke in and fought here..."

Thinking of the battle, Xia Lei's thinking suddenly paused and a new question emerged.

The bodies here are all knights of the Knights of the Hospital, and there are no personnel from the second party. The problem lies here, there is no enemy. Could it be that the knights of the Knights of the Hospital, who died of killing each other? If they died of killing each other, why would they die of killing each other?

Xia Lei's eyes quickly swept through several corpses, and soon his sight stopped on one of them. He walked over and reached out to pull out a cowhide bag in the robes of the corpse.

The cowhide bag is treated with tung oil and is not destroyed due to its age. There is no dust here, it looks even clean and maintains a minimum of toughness. The cowhide bag also has the emblem of the Hospital Knights, which looks a bit like what is in the current file package.

Xia Lei opened the cowhide bag and took out the things inside.

The cowhide bag contained several Malta Eagle coins, a silver cross, and a letter that had not been opened. The letter was sealed with fire lacquer wax, with the seal of the Knights of the Hospital.

Xia Lei opened the letter and saw the content above: Lord Commander, we encountered an ambush in Bobio, and there were heavy casualties, but we defeated our opponents. We found the maze north of Bobio, and I have to admit that Da Vinci is the smartest man in the world. It took us half a month to open the passage. I should send this letter out and go in, but my messenger has died in battle. In order to prevent accidents and possible battles at any time, I decided to enter the maze first, and then send a letter to you after coming out. God's metal will definitely belong to the great hospital knights, and victory will also belong to the great hospital knights, and the kingdom will be rebuilt.

The letter ends with the letterwriter's signature: The Spear of God, Baron Silver Feather, Loyalty Knight, Varev

After reading the letter, Xia Lei's gaze was still on three Italian words, that is, God's metal.

Although no word is related to "ancient alloy", he has an intuition that the "divine metal" mentioned by the knight leader Varev, who wrote the letter, is ancient alloy.

The knights of the Knights of the Hospital came here for nothing else, it was the ancient alloy!

Thinking of this, Xia Lei's heart beat violently. Could it be that the last piece of ancient alloy is in this underground maze? What Leonardo da Vinci said was the last piece of ancient alloy?

If this is true, then the expedition is worth it!

"Wait..." Xia Lei suddenly remembered the compass, and his excitement disappeared halfway. "The compass can correctly guide the ancient alloy where it is hidden, which is more effective than satellite positioning. The last pointer is installed on the compass, which clearly points to the sky and has never pointed out the direction of Italy. How could there be the last piece of metal in this underground maze? Could it be that the information obtained by the Knights of these hospitals is wrong? Or is it something else?"

Huhu...

Suddenly a gust of wind blew.
