And under the stone statue of the demon demon, there is something buried half in the soil, and there is something exposed, obviously a piece of iron! There seems to be words on the iron! This is a piece of iron with records! Somehow, I had to dig this piece of iron deep into it, and the material wrapped around it was actually glass!

These glasses have a lot of transparency, but this island has disappeared for so many years. It seems that no one has climbed it for at least a hundred years, and there is actually glass? How could there be glass? There was glass hundreds of years ago?

However, Yuan Chengzu explained the situation of glass: "If you want to talk about glass, it has existed a long time ago. Small glass beads were unearthed in the remains of Mesopotamia and ancient Egypt 4,000 years ago. More than 3,000 years ago, a European Phoenician merchant ship discovered glass when he was burying a pot to make rice and using a few pieces of natural soda as a bracket."

Yuan Chengzu looked at the glass again and said, "In the 4th century, the ancient Romans applied glass to doors and windows. In 1291, the glass manufacturing technology in Italy was very developed! In 1688, a man named Naf invented the process of making large pieces of glass, and since then, glass became an ordinary item. The bis in the Han Dynasty, which was displaced by glass, was also introduced to our country. During the Three Kingdoms, Emperor Sun Liang of the Eastern Wu, possessed glass screens. When Emperor Taiwu of the Northern Wei Dynasty, Tuoba Tao, some outsiders even introduced glass manufacturing technology."

"During the Song Dynasty, glass manufacturing technology was developed, but in the Yuan Dynasty, it was natural that it was not enough. The Ming Dynasty also followed the Yuan Dynasty. In the Qing Dynasty, Emperor Kangxi invited German missionary and technician Ji Li'an to provide technical guidance, thus creating the Qing Palace Glass Factory! In the Yongzheng Dynasty, there was a glass screen, which ended the history of Chinese paper-paste windows."

Yuan Chengzu looked at the glass and said, "From this point, it was normal to have glass here hundreds of years ago! Moreover, it was occupied by the Netherlands and there was overseas trade, so it was not surprising that glass could be obtained!"

After Yuan Chengzu's explanation, everyone felt relieved. They knew that glass was very good for decades of old houses, which proved that these glasses were very preservative. Especially modern archaeology found in the tomb of Liu Sheng, King Jing of Zhongshan, Han Dynasty, which was different from Western glass, which was preserved for two thousand years! And it is normal that the glass in front of them can be preserved for hundreds of years.

Everyone looked at the iron block through the glass, but they didn't expect that the captain would have looked at it. When he saw that his eyes were blurred, he had abnormalities! It was just that the change of his eyes, no one could observe it in this dark environment, and most of the people's attention was focused on the iron block because the words were engraved on the iron block.

The captain changed, and his eyes all changed! It was his change that he would take action.

The iron block carved the ten words "Made in the April of the Sixth Year of the Heavenly Revelation" which shows when it was made and where it was made.

Tianqi was the reign of Emperor Xizong of the Ming Dynasty, Zhu Youxiao. Wang Gongchang is very famous because Wang Gongchang is a royal arsenal, also known as the Gunpowder Bureau. When it comes to Wang Gongchang, we have to mention the explosion of Wang Gongchang. The explosion of Wang Gongchang is the "Dead Hill Incident" in ancient India and the "Tungus Big Bang" in Russia are called the three mystery of nature in the world.

There were 10,000 deaths in the Wanggongchang explosion, and thousands of victims were killed by famous and surnameds. This explosion changed history even more. The crown prince Zhu Cijing, who was less than one year old, was smashed to death in the palace. Zhu Cijing did not die, and Emperor Xizong of Ming Dynasty had an heir, Zhu Youjian could not succeed to the throne, and there was no Ming Sizong. As for whether the Ming Dynasty would perish, it was unknown. It was just that there was no assumption in history.

This big explosion was strange, "the dead and the injured were all naked", and their clothes were floating on the mountain, and their limbs were scattered in the distance. In the Chang'an Street area, people's heads, eyebrows, noses, or foreheads were occasionally flying down from the sky. Outside Desheng Gate, there were countless people falling arms and legs, accompanied by wood, stones, poultry, etc., falling like rain. The scene was terrible.

On Shifuma Street, a stone lion weighing 5,000 kilograms flew out of Shuncheng Gate, and the trees flew to Miyun. It can be seen how powerful it is. Even a stone lion weighing 5,000 kilograms can fly out such a long distance!

If it was the Wang Gongchang explosion, then the disaster "don't burn a small tree" and "there is no trace of burning fire". If it was an earthquake, it was inconsistent with the earthquake. As for tornadoes, meteorites, etc., it could not be explained. It is precisely because of these reasons that the Wang Gongchang explosion is called the mystery of the three major explosions.

Now this piece is called a monument, but it is better to say it is a big iron block. I wonder what this big iron block is used for, so why is it made in Wanggong Factory? This is the royal arsenal! It is not a big iron block that can be made here by casual cats and dogs.

Only a person with a very high status can create such a large iron block. But what is the use of such a large iron block? What is it used for? I saw it buried here, buried in the center of the island, and only one head was exposed.

Everyone looked around, but they still couldn't see one. They thought that the big explosion in Wanggong Factory was in May and this big iron block was made in June. Could it be that the two had a big relationship? Could it be that the big explosion in Wanggong Factory was also related to this iron block?

Cao Yusen stared at the big iron block in a steady state and said, "I always feel that this iron block seems to be a bit familiar. This feeling is seen at first glance! To be honest, I don't understand why I feel this way!"

The fat man was joking, saying, "Yu Sen, this big iron piece was not made by you, right? If you made it, everything on the island would be related to you! Haha!"

Cao Yusen shook his head and said, "Fatty, don't make fun of me! To be honest, I don't know why I felt familiar at first sight! Now if I look closely, I feel that the feeling is almost gone! Maybe it's a temporary illusion!"

Cao Yusen, sometimes it is not a human illusion, because a human first sense is very important, and sometimes the first sense is so accurate. How can you not take it seriously? This should be more trustworthy than missed...

Ren Feng said helplessly: "How could this happen? It was the Ryukyu Kingdom at one time, and the Yue Kingdom at the Spring and Autumn Period and the Warring States Period. Now it was the Tianqi period of the Ming Dynasty, and it became more and more messy! Just tell the turtle cave directly! Why do you do these unrelated things?"

Since Ren Feng said it was irrelevant, do you think that the things found on the island are really irrelevant? Cao Yusen and others did not think that it was irrelevant.

It may be because of the mysterious and confusing so many things that people who climb the island cannot find the way to the turtle cave and reach the turtle cave.

But there is also a possibility that these are all related, but people do not get relevant clues, so they naturally cannot connect everything to crack it.
