The Iron Birch Tree is not a legend, but it does exist, but it is not as exaggerated as the rumors that invulnerability and bullets cannot leave traces.

According to the records of "The World's Best - Plant Fascicle", the true hardness of iron birch is twice as hard as that of ordinary carbon steel. It may not be a good idea to say this, but in other words, it was about as hard as a one-dollar coin today.

The main reason why it is so hard is that the iron birch tree grows very slowly, the wood is dense, and in the process of growing, it absorbs the silicon in the soil, so it is much harder than other trees.

Due to the slow growth of iron birch trees and the harsh soil quality, they are now very rare, and only a few grow in Siberia. The vast majority of the so-called iron birch on the market is counterfeit rue wood.

Ye Xuan was not too surprised by the use of iron birch for shipbuilding, after all, Mao Xiong had used them to make ship accessories. What shocked him was that the entire ship seemed to be made of iron birch, which was a bit of an exaggeration.

You know, the iron birch is not stout, the whole ship is about 40 meters long, if it is all made of iron birch, it will take thousands, at least, unless the people who built the ship in the first place swept the whole of Siberia, it is impossible to make it together.

But it also explains why the wooden boat, which looks broken and decayed, is not afraid of strong winds and waves.

Ye Xuan took out the dagger and slashed it on the railing. As a result, the sharp dagger left only a shallow mark on it. Gently stroking the knife marks, he couldn't help but sigh with emotion: "What a extravagant person this must be to do such a thing as building a ship with iron birch." ”

You know, the Middle Ages were no better than modern times, when metals were extremely scarce and belonged to hard currency. And the hardness of iron birch, which is comparable to that of metal, will only be high in price. So the price of this ship at that time was definitely astronomical.

Heavy rain is still falling, and there is no telling how long this storm will last.

It's safe now, and this level of wind and waves is not enough to pose a deadly threat to a ship as big as steel. Take advantage of this time to explore the ship.

His heart was now filled with curiosity.

Holding the dagger, Ye Xuan walked slowly along the bow deck towards the captain's room.

The ship was very high, there were no superfluous buildings on the deck, and the places where the sailors stayed and ate should have been in the cabins below.

The door was not closed, and Ye Xuan walked in.

The whole captain's cabin was not large, only three or four square meters, and the wall and window in front of the rudder were once inlaid with a small piece of glass, but now the glass has long been shattered and scattered on the ground. From time to time, rain blows in through the window along the sea breeze, making the room extra damp and smelling of decay.

Ye Xuan squatted down, picked up a glass shard from the ground, and looked at it carefully.

The glass is not too pure, with a hint of tawny tint. This discovery made him swallow his saliva.

Although the real colorless glass was made in the early years of the Song Dynasty, the process at that time could only make glass into some small ornaments. It wasn't until the 16th century that Europeans invented the craft of making large pieces of glass.

Judging by the size of the window, this piece of glass is not large, which indicates that the ship was built before the 16th century. After all, if you can build a ship out of iron birch, how can you not afford a large piece of glass. So the only explanation is that at that time, there was no process for making large pieces of glass.

And judging from the purity of the glass in his hand, the purification process is not developed enough, Ye Xuan estimates that the real construction time of this ship will be postponed, about the 14th century.

This ship has probably been at sea for more than five or six hundred years? It's incredible.

But if you think about it, it's possible.

Ye Xuan vaguely remembered that the world's longest-lived ship should be the Constitution of Lao Mei, this out-and-out wooden ship was launched in 1765, and to this day, it can still sail and even fight, and every year Lao Mei will drive the Constitution out for a walk.

He didn't know what the wood used in the hull of the Constitution was, but it was certainly not iron birch, which has survived to this day, mainly due to maintenance and repairs. If this ship had been constantly maintained and repaired in the first two or three hundred years, it would have been used for hundreds of years.

There was nothing left of the captain's cabin except for shards of glass all over the floor. There may have been, but now they have all been lost in the long river of time. The doors were not closed, the windows were shattered, the wind and the sun were exposed to the rain and it was impossible to preserve things in this harsh environment.

After looking around and making sure that nothing was missing, Ye Xuan slowly walked out of the captain's room and walked towards the entrance of the cabin.

The entrance to the cabin is actually a downward-sloping staircase walkway, with a small door at the entrance open and rainwater flowing down the deck and all the way down the staircase.

Seeing this scene, Ye Xuan couldn't help frowning, he was already hopeless in the cabin. To be sure, the cabin, if not flooded, was so damp that the contents could not be preserved. Not to mention hundreds of years, more than ten years is enough time for the contents to rot.

It was pitch black in the passage, and when I leaned my head over, a strong musty smell suddenly hit my nose, mixed with the smell of rot.

After hesitating, Ye Xuan still decided to go down and have a look. After all, ghost ships are not common, let alone such an old ghost ship, board the ship at this time, if you don't go down to have a look, it is estimated that it will be very regrettable in the future.

Use a dagger to cut a strip of cloth under the hem of a T-shirt to act as a makeshift mask to cover your nose and mouth. Even though it didn't smell rancid, it was a matter of seconds. Then, he took out his mobile phone from his pocket, turned on the flashlight function, and when he was ready, he carefully walked into the passage with a dagger.

The ship has drifted on the sea for an unknown amount of time, and the wooden staircase even has a layer of moss, and the rain has washed it out, making it look particularly slippery.

The stairs were not long, and soon he descended into the cabin.

"Whoa!"

The floor in the cabin has been covered with a shallow layer of rainwater, and the sound of splashing is clear when shoes are stepped on it. The entire cabin was silent, except for the sound of his own breathing and heartbeat, but there was no sound again.

For a while, Ye Xuan even suspected that he was at the scene of a horror movie.

The experience of surviving in the wilderness has allowed him to maintain good habits, and when he first arrives in an unfamiliar environment, he will always slow down or stop directly, allowing his senses to adapt to the environment first.

After standing quietly in place for a few minutes, Ye Xuan held the dagger in one hand, crossed it in front of his chest, raised his mobile phone in the other, and slowly walked forward along the corridor.

In fact, to be honest, he didn't think that there would be animals in this cabin that could pose a threat to him. The reason for this is just habit.

After walking about ten steps, he found a room next to him by the light of his mobile phone.

The door was open, and Ye Xuan held his mobile phone to take a picture inside. It appeared to be a crew's bedroom, only a few square meters, empty and the original bed furniture completely rotten.

After exiting the room, he moved on. By the way to the end, he had explored seven or eight rooms, but the results were all the same as the first one, and he didn't find any useful information or objects. All the way to the end of the cabin, where there was a relatively large room.

Originally, Ye Xuan didn't have much hope, and when he was about to turn around and leave, he suddenly raised his eyebrows.

"Huh!"

I saw that in the corner near the door, there seemed to be something well-preserved.
