A group of people were very unwilling to give up and almost wanted to dig three feet into the ground to see if they could find a surviving martial arts book, but was eventually stopped by Sun Yan.
This city is still as complete as new and must have a mysterious battle mark. If it is easily touched, the consequences will be unpredictable.
"There is that energy breath." Sun Yan pointed to the depths of the library.
Everyone then realized and walked straight to the depths of the library. On a table, there was a transparent box with golden gems sealed.
This golden gem has never been seen before. The box was not locked. After opening it, it took out one. Immediately, a strong energy surged out, filled with a fragrance. It made people feel energetic and their whole body was filled with blood.
"What pure energy! This is a life gem!" Jing Taichu showed a shock. He had seen records similar to gems in the ancient books of the family.
Tian Poxiao was also surprised. He had seen similar records, "The life gem, in ancient books, has another name - the universe rough stone. The energy contained in this gem is powerful and mysterious. Whether it is used for cultivation or for casting weapons, it has unimaginable magical uses."
Everyone's eyes became hot, and a whole box of life gemstones, even if the specific purpose is unknown, is still priceless and incalculable.
To be precise, any thing in this library has unimaginable value, but unfortunately, those peerless martial arts scriptures have been emptied.
"Huh..., there is a letter here."
Suddenly, Sun Yan found a letter at the corner of the table, and the signature of the envelope shocked him, and it turned out to be Sun Liexue.
"My uncle has been here!?" Sun Yan was surprised.
The eyes of the people around him suddenly became hot. They were both shocked and expected. Sun Yan's ancestors had actually been here, so the whereabouts of the library's books might have been moved away by this ancestor.
"There are strong battle marks on this envelope, and you cannot forcefully open them." Jing Taichu said with a look.
The envelope is very clear on the surface. If a later member enters the library and finds this letter, he will send it back to the Sun family of the Earth Alliance, and the reward is this box of life gemstones.
The method of opening the envelope is the blood of the descendants of the Sun family. Forcibly opening the letter will cause great disaster.
"Uncle, you not only came to the starry battlefield, but also came here." Sun Yan was in a state of great emotion as he held the letter.
The uncle of the Sun family was amazing, with great perseverance and courage. In such an ancient era, the martial arts civilization of the Earth Alliance was extremely backward, so he practiced to the title of Martial Arts.
It is indeed not recorded in history that Sun Liexue was actually the first warrior in the Earth Alliance, and later he crossed the starry sky to find the location of the starry sky battlefield.
It can be imagined that this uncle killed himself in his cultivation, fell from the title realm, and re-educated in the starry battlefield.
Not only did he refresh the Odin battle post, he became the first in Dongfang Huang before, surpassing Wu Yan Bridge, but later entered Fengyun City and came to this mysterious city.
"Perhaps, the base on the Starry Sky Battlefield was also obtained by my uncle."
Thinking of Sun Liexu's past style, Sun Yan was fascinated by his leisurely nature. In fact, the Sun family has been no longer ordinary since the dark era.
With a flick of his finger, a drop of blood dripped, and the envelope light flowed, then it opened, and there was a letter and a map inside.
The content of the letter is about Sun Liexue's experience in the starry sky battlefield and some information about this giant dragon skull.
As Sun Yan guessed, thousands of years ago, Sun Liexu came to the starry battlefield and was alone for a lifetime, without a companion from the Earth Alliance here.
With his fists, he made a desperate battle, killed dozens of eight-forged monsters in Fengyun City, obtained massive resources, and opened up the base of the Earth Alliance.
Later, three companions arrived one after another, namely Wuyanqiao, Bai Shura, and Rog.
Afterwards, the four of them went deep into the central urban area of Fengyun City, and they reached the end all the way, and found the giant dragon skull and the empty city...
"Empty city..., thousands of years ago, the library was emptied? Only some supplies exist."
When everyone learned the truth, they were all lost. It is true that the gem of life is priceless and extremely attractive. However, the amazing martial arts can be passed down from generation to generation, which makes people desire, but none of them have been saved.
The map in the envelope shows the terrain of the central urban passage and half of the terrain of the giant dragon skull.
The letter stated that this giant dragon skull was very broad, and even with the strength of Sun Liexue and the other four, it was not fully explored.
At the end of the letter, he told the descendants of the Sun family that if a stunning genius appears in the Sun family, he can come to the starry sky battlefield and seal the relics of Sun Lie's blood on the highest floor of Fenglou, and only the blood of the descendants of the Sun family can be opened.
After reading this letter, the group was shocked. Sun Liexu's name was not noticeable, but his three companions, Wu Yanqiao, Bai Shura and Rog, were all outstanding figures in the Earth Alliance.
Thousands of years ago, the existence of the peerless Wu Yanqiao and the mysterious Bai Shura, the two outstanding figures, made the imperial clan deeply afraid.
Now that time has passed, Wu Yanqiao's remaining power remains, it can be seen that the reputation of this peerless Wuzong is so high.
"Sun Liexue, thousands of years ago, swept across Fengyun City and killed dozens of monsters in the Eight Forging Realm. If it emerged from nowhere, it would probably be no less than Wu Yanqiao." Duan Ruxue couldn't help but sigh.
"A such a peerless genius is probably better than Wu Yanqiao's martial arts achievements, perhaps because of the impact of the Nine Forging Realm..."
Yuan Zhan looked at Sun Yan and did not continue to talk. In the history of the Earth Alliance, Sun Lie's blood reputation was unknown. From this, it can be seen that it is very likely that the failure to hit the Nine Forging Realm, and the peerless genius will be destroyed from then on.
Sun Yan was silent and then smiled and said, "If you can get news about your uncle, you can also give your father an explanation after returning to the Earth Alliance."
At this time, someone rushed in and reported to Jing Taichu that he found a team of imperial clan forces on the edge of the city.
"These grandsons did not die in the storm of energy." Tian Poxiao snorted coldly.
"They came just right! The map in our hands is probably more complete than that in Fan Qilin's hands." Jing Taichu smiled, as if she was a smiling fox.
Everyone understood and gathered together. After a moment of discussion, they took action, arranged some arrangements, and quickly evacuated.
In this empty city, the cold wind blew by, and the sound of whining sounds sounded on the streets without any popularity.
If this news spreads out in the empty city in the dragon skull, it will definitely cause a great shock in the pan-star domain, which involves many mysteries.
The sky above the city is very bright, and the giant dragon skull is made of metal, emitting a soft light, illuminating the city very clearly.
Looking at the empty bookshelf, the titles of the books are legendary peerless martial arts, some of which really exist only in legends and are simply unable to find them now.
