Rou Yi and Li Decha began to study the collected leather scrolls after Fatty and the others left.

　　Han Yu sat quietly aside, found a piece of paper and a pen, and began to do some verification and derivation. It is estimated that no one but herself could understand what she was writing.

　　The leather scrolls were well preserved. After so long, they had not been damaged or corrupted.

　　Rou Yi thought that the words on these leather scrolls might record the history of Stone City and the evidence of its destruction, and perhaps they could find the location of the gate to the seabed on the leather scrolls to help the young master find a way to reverse aging.

　　The hieroglyphs on the leather scrolls looked extremely complicated and too abstract. Each character looked like a simple drawing, and it would take a lot of time just to distinguish the structure of the characters.

　　The hieroglyphs of the Gakuye God Kingdom in front of the words on the leather scrolls were like comparing a book for a kindergarten literacy class with the obscure and difficult inscription rubbings studied by archaeological experts.

　　Li Decha found a breakthrough. He said to Rou Yi: "Do you remember that more than 3,000 years ago, there was a Mayan civilization in Central America? Are Mayan characters a bit like the characters on the leather scrolls?"

　　Rou Yi was enlightened. The strange feeling she had when she saw these characters was answered at this moment.

　　Rou Yi said excitedly: "Yes! It's Mayan writing!"

　　After finding the reference, Rou Yi and Li Decha quickly divided the work and sorted out the characters on the leather scrolls according to the structure and grammar of the previous Mayan characters.

　　The characters on the leather scrolls were obviously more primitive and ancient than Mayan characters. Li Decha had specialized in Mayan characters when he was in college, so he knew more about hieroglyphs that were homologous to Mayan characters.

　　The two successfully translated most of the content on the leather scrolls by means of extracting words, transliterating, and reordering. The untranslated words were also derived from the meaning of the context.

　　The first leather scroll tells the origin of Stone City:

　　About five thousand years ago, one of the tribes of the Mayan ancestors living in Central America was forced to abandon their original territory and go to sea to find a new habitat in order to avoid disputes between the tribes.

　　The tribe made a large number of simple wooden boats, and more than 200 people set off from the east coast of the Americas to find land where they could survive.

　　The weather at sea was unpredictable, and simple wooden boats could not travel long distances. Many wooden boats were swallowed by the sea in the process of searching for islands.

　　Finally, they found a suitable island to live on in an area of the Bermuda Triangle. At this time, they had only less than a hundred people left.

　　They opened mountains and凿stones on this island to build new habitats and multiply on the island.

　　The second and third leather scrolls tell the story of people's lives in Stone City.

　　After landing on the island, people found that the habits of living on land were not applicable here.

　　The land here is saline-alkali land, which can hardly grow food. All the crop seeds they brought from the land were wasted. They could only be forced to go to sea to fish. From then on, all their food came from the sea.

　　There were many trees, vegetation, and wild fruits on the island at first. Due to the large-scale felling and picking by the tribes over the generations, coupled with the fact that the people in the tribe did not know how to cultivate seedlings and protect the ecology, the green trees and colorful fruits were quickly exhausted.

　　Insufficient resources will lead to uneven distribution. At this time, conflicts and frictions occurred within the tribe. In the conflicts and struggles, the tribe gradually formed a strict hierarchical order.

　　In order to maintain the ruling order of the high-level people, the tribe also formulated and implemented strict moral laws, and the primitive tribe slowly took the form of a country.

　　The harsh laws even stipulated the amount of fish caught by adult men every day. If they did not reach this amount, they would be punished, such as being deprived of their houses and property, becoming slaves, and being sent to do hard labor to build the rulers' mausoleums—pyramids.

　　A considerable number of low-level people died of exhaustion in the process of doing hard labor.

　　Even after death, these dead low-level people were still contributing to the high-level people. Their meat was a tribute on the table of the ruling class, and the most essential human brain was food that only the city lord could enjoy; their bones were made into various utensils and decorations; even their skin would be peeled off. The complete ones without scars would be used to make leather scrolls to record important content, and the incomplete ones with scars would be used to make leather bags or gloves, shoes, and other less important items.

　　After the level was solidified, the level of people only depended on their origin. For example, the children of low-level people were destined to be low-level, and the children of high-level people were high-level from birth to death.

　　In order to supplement labor, Stone City encouraged childbirth, and low-level people could obtain the possibility of level improvement by having more children.

　　The scale of Stone City is getting bigger and bigger, from the earliest few stone houses by the sea, it has gradually expanded into a castle with inner and outer cities.

　　The difficulty of going to sea at that time is hard to imagine today. Stone City has become a 'paradise' to avoid wars and chaos, and the sea is their natural barrier to defend against foreign enemies.

　　At the same time, most people on the island have no way to escape from now on. They are born on the island and die on the island for the rest of their lives.

　　The island is rich in crystal clear spar. Every year, Stone City will send people to the land to exchange some stones for things that are not available in the sea, such as cloth and brocade, but many of the people sent out rarely return. It is unknown whether they escaped to the land or were buried in the sea on the way.

　　The text records were initially engraved on stones, but after experiencing the unpredictable wind and rain attacks at sea and the erosion of seawater, the handwriting on the stones was quickly wiped out. Lacking wood, lacking paper, and lacking the conditions for animal husbandry and breeding on the island, stone carvings have become ineffective if you want to record history for a long time.

　　Eventually, the rulers focused the carrier of text records on human skin.

　　The lack of materials did not bring about the progress of science and technology in Stone City, and the closed environment made the people of Stone City gradually become numb. The ruling grassroots took pleasure in **, punishment, and execution. The cultural accumulation of Stone City only left the experience of "ruling people" (domination, calendar) and "using people" (eating people, human bone utensils).

　　The remaining leather scrolls tell a story of a "heavenly flying star."
