There is an ancient tomb in the deepest part of the cave! Yuan Dao once studied ancient history and cultural relics in depth in order to identify the symbols and words on those magic weapons, but with what he learned in his life, he still couldn't identify what age this ancient tomb was.

The ancient tomb is very huge, and the deepest part of the cave has become a very empty underground 'underground palace', and there is basically nothing in the underground palace, only a huge coffin.

Out of curiosity, Yuan Dao pried open the coffin with a dagger, and there were no bones in it, only such a strange object that looked like a bell but also looked like a wine bottle.

Who would put such a coffin here, and what is this object in the coffin!

At that time, after Yuan Dao escaped from the pursuit of the killers of the Temple of the Gods, he returned to the Zhuxia base camp, and after his long-term research, he consulted countless materials and documents, and did not recognize what this thing was.

"Sikong Yuyang must know more than me...... Maybe...... He's going to be interested in this 'bronze bell'!" Yuan Dao finally showed a slight arc at the corner of his mouth when he remembered the object.

This mysterious object comes from a coffin in an ancient era, with some mysterious symbols engraved on it, Yuan Dao is very confident, Sikong Yuyang will be very interested when he sees it.

Although Yuan Dao didn't want to give this object to Sikong Yuyang, there was no other way now!

He expected that in addition to the bronze tripods and pottery shards engraved with mysterious symbols, Sikong Yuyang would also be very interested in this 'bronze bell'!

The name 'Bronze Bell' was given by Yuan Dao himself, in fact, even Yuan Dao did not know what material this object was made of.

He once used a spectrum analyzer from a laboratory in Zhuxia to conduct a spectral analysis of this object, hoping to get an answer.

However, modern state-of-the-art optical spectrum analyzers cannot analyze the spectrum of this object!

It seems that this thing should not exist in this world!

Even, later, Yuan Dao deliberately went to the mysterious cave, with some scientific instruments, to analyze the coffin located in the cave's 'underground palace', and after the elemental isotope analysis of the relevant instruments, he came to a conclusion that made Yuan Dao very shocked.

This conclusion is that 'the coffin in the cave underground palace is 20,000 years old!'

The material of the coffin is carved from the most ordinary limestone, like a huge piece of limestone, and someone has hollowed out the inside with a tool, and then made the shape of such a coffin.

Yuan Dao clearly knows that the written history of human beings is only 2,000 years, and even if there are some ancient legends, it is only about 5,000 years.

Isn't it said that there is a 5,000-year-old civilization in China, although those legends of about 5,000 years have been impossible to verify, such as the legends of the Three Emperors and Five Emperors, there is no written record, only legends, and there is no way to verify at all.

However, scientific instruments will never deceive people! According to the scientific analysis of some dust and internal nicks in this coffin, it is indeed 20,000 years old!

At that time, the data analyzed by the instrument really shocked Deyuan Dao, 20,000 years ago...... At that time, it was still primitive humans, and this coffin was made by hollowing out limestone, which may be understandable, but the objects inside the coffin are so exquisite, how could primitive humans make them!

At that time, Yuan Dao immediately thought of 'aliens'!

Was it the 'aliens' who made this amazing object?

However, as time passed, Yuan Dao vetoed the conjecture of 'aliens' with great certainty!

Aliens?

Subsequently, Yuan Dao had a new conjecture that the exquisite objects in the cave coffin may have been made by a certain race that was more developed than other primitive races in the past, and it is likely that they became extinct due to a climate disaster.

The Sanxingdui civilization has a history of 4,000 years, and it can produce very exquisite gold artifacts! The degree of development of some ancient civilizations is far beyond people's imagination, perhaps it is just that the time interval is too long, and the traces of the existence of those civilizations have been eroded by tens of thousands of years.

After thinking of a countermeasure, Yuan Dao took out his mobile phone, pressed a long string of numbers, and then pressed the dial button again.

Soon, the phone was connected, and a cold voice came from the receiver of the mobile phone.

"Your Majesty, Tsukasa Tiger is waiting! What are the king's orders?"

This person's voice was extremely cold, not ordinary cold, just like the kind of voice made by a person who had been dead for hundreds of years, and listening to it would make people's scalp tingle and cold.

"Tsukasa Hu, I will now give you permission to all the rooms of the Zhuxia Great Base Camp Palace, and you can help me go to the 'Abyss' room in the deepest part of the dungeon to get a few things out!" Yuan Dao said unceremoniously.

Tsukasa Tiger, one of the four dry summers!

Zhuxia Siqian is the four people who are more powerful than Bakun, except for Tsukasa Hu, the other four people are 'Youlin, Feng Xiao, Wolong!'

These four people, each of whom is strong to the point of perversion, are the first brothers to follow Yuan Dao to fight the world together, among which Tsukasa Tiger was seriously injured in a battle, and now his legs, feet, and one eye and heart are made of alloy, Yuan Dao did not let him continue to go out on a mission, but stayed in the base camp 'Gatekeeper Hospital'.

Although Rao is Tsukasa Tiger has now become a 'disabled person', after Yuan Dao helped him make an alloy prosthesis at all costs, he can now move freely, but his combat effectiveness may have decreased slightly.

Tsukasa Hu often said that he was now reborn, and his combat effectiveness was stronger than before, and he often begged Yuan Dao to let him go out on a mission, but Yuan Dao just refused, so he had to obediently obey the orders to stay in the base camp.

Yuan Dao is based on two considerations.

First, with the increasing perfection of the genetic modification technology of the Temple of the Gods and the Alliance of Order, there must be a strong man to guard the base camp! Even if the Temple of the Gods and the Alliance of Order sent killers to besiege the base camp of Zhuxia, as long as there is a Tsukasa Tiger, Yuan Dao is not afraid that his nest will be wiped out!

For Tsukasa Hu's mind and strength, Yuan Dao is extremely relieved, for so many years, Yuan Dao's understanding of Siqian even surpasses his own!

Second, Tsukasa Tiger was once seriously wounded in a fierce battle, and his heart was penetrated by shrapnel after carpet bombing, and later spent all the scientific and technological personnel and huge funds of Zhuxia to develop an alloy heart to implant Tsukasa Tiger in the chest cavity.

Although Tsukasa Tiger looks no different from a normal person now, Yuan Dao doesn't dare to guarantee that if Tsukasa Tiger is in an extremely fierce battle, there will be something wrong with this alloy heart!

Si Qian is the treasure of Yuan Dao! Yuan Dao is reluctant to let any of them die!
