The people of Penglai Cave have a very leisurely life, the average life expectancy of each person is about 6,000 years old, they do not need to work, and there is no competitive pressure, as long as they can be self-sufficient. The reason why they can live so long is because there is an old tree spirit with great powers living in the cave, and the people in the cave call him "old fairy".

Penglai Dongtian was originally a deserted island that no one cared about, located on the edge of the Bohai Sea. After the invention of the ship, some strange people from the Central Plains explored this place one after another.

By the time of the Spring and Autumn Period and the Warring States Period, it gradually became a gathering place for strange people, because it was rumored that there were immortals living here, and as long as they ate the elixir given by the immortals, they could live forever. This attracted a large number of strange people to come here to seek immortals and medicines, and these so-called strange people were the first batch of superpowers that emerged in the earliest period of human beings.

However, there are no immortals living on Penglai Island, but there is an ancient tree that has lived for tens of thousands of years, called "Vicissitudes", this tree has the ability to live endlessly, immortal, and is a unique strange tree between heaven and earth. This ancient tree has lived for too long, and over time it has developed a spirit comparable to that of humans, and after seeing the existence of humans for the first time, it has developed a strong interest in humans as creatures.

Although the Vicissitudes Tree cannot move, it can learn the language of man, and it gradually learns that human beings have a very limited lifespan, at most seventy or eighty years, and will be buried in the earth after death. Although the life span of a human being is extremely short compared to it, it is extremely free, and it hopes that one day it will become like a human being, with a dexterous body that can speak freely and move freely, instead of being trapped in the soil where it is rooted, immobile.

At that time, there was a charlatan who could communicate with plants found it, this person was named Xu Fu, a strange person who was proficient in the art of numerology, he had been looking for the method of immortality and death, and after years of calculation, he finally found the longest living vicissitudes of life in the world. He was pleasantly surprised to find that the wisdom of the vicissitudes of the tree is extremely high, and there is really a way to increase people's lifespan, that is, to use its own essence to produce tree fruits, human beings can live forever as long as they eat the fruit it bears, although they can't live without old age and death, but it is not a problem to live for thousands of years.

However, the Vicissitudes Tree made a condition that Xu Fu bury a complete human corpse under its roots. Xu Fu was shocked when he heard this, thinking that this was a demon tree, but instead of agreeing to the conditions of the vicissitudes of life, he also threatened to find someone to cut it down. The Vicissitudes of Life Tree has extremely high wisdom, in order to survive, it had to pretend to submit to Xu Fu, and expressed its willingness to bear the fruit of the immortal tree for it, just begging not to kill it, it took a month to produce a tree fruit, falsely claiming that this is an immortal fruit that can prolong people's life.

Xu Fu didn't have any scheming, he believed it, and ate the poisonous tree fruit on the spot and died under the tree. Coincidentally, after a little while, a kind person passed by here, found Xu Fu's corpse, saw that it was pitiful, so he dug a pit and buried it on the spot, the vicissitudes of life originally just wanted to poison this human who wanted to kill it, but I didn't expect that by chance, a complete human corpse was obtained in vain.

The only part of the vicissitudes of the tree that can move is its roots, which wrapped Xu Fu's corpse with the roots, and nourished the corpse with plant nutrients for decades, not only bringing this body back to life, but also pinning all the wisdom of its body on this person.

The reborn Vicissitudes of Life began to travel around the world, learning from teachers in various places, and made good achievements in martial arts, medicine, literature, and even learned some Taoist spells that have long been lost today. Because he lived too long, in order to avoid suspicion, he had to change his name and identity every thirty or fifty years, and his life was extremely free.

Later, during the Warring States Period, there were constant disputes between countries and the people were struggling to make a living, and the vicissitudes of life, who were deeply disgusted by it, had the idea of living in seclusion in Penglai. But it was a little lonely to go back alone, so he called some strange people he had made friends with, invited them to go to Penglai Island with him to escape the troubled times, and also used the immortal fruit produced by the body to prolong their lives, so there were rumors that there was an elixir on Penglai Island.

It was not easy to wait until the Qin Dynasty unified the six countries, Qin Shi Huang's tyranny, and the government made people shudder, and the residents of Penglai Island were still reluctant to return to the Central Plains, but the rumors of the elixir had spread on the Central Plains Continent, and Penglai Island was suddenly in a state of turmoil. The vicissitudes of life were worried that Penglai Island would be affected, so he deceived Qin Shi Huang in the name of Xu Fu, and deceived a lot of manpower and materials from Qin Shi Huang, which took nine years to build Penglai Island into a cave, and with the help of other strange people, he arranged the Xuanqi Great Array.

"Xu Fu" finally went to Qin Shi Huang to defraud the last manpower and materials, and then sank the entire Penglai Cave to the bottom of the sea, and has been isolated from the world ever since.

This story is what Guo Jia read from "Penglai Ji", and it is a book that Guo Jia cheekily asked the readers here to borrow. Guo Jia has been looking for a way to leave Penglai Dongtian, and he borrows a lot of books from local readers from time to time to read on the pretext of passing the time. But in addition to this "Penglai Ji", most of the other books are some literary poetry classics or traditional Chinese medicine classics, as well as Chinese dictionaries, which are "imported books" brought by the old gods from the outside world, and it is no wonder that people here speak modern Chinese.

However, these are not the point, the Xuanqi Great Array recorded in "Penglai Ji" should be an important clue to leave Penglai Cave, but other books do not have any information about the Xuanqi Great Array, and he can't help but be a little discouraged.

The three meals a day here are mainly seafood, Guo Jia doesn't like to eat seafood very much, such days are simply torture for him, he didn't have much meat on his body and became thinner and thinner, and even had the heart to commit suicide, but fortunately, things quickly took a turn for the better.

One morning, Guo Jia was summoned to Penglai Xianju again, and the elders gave him a brocade box, which contained a strange fruit shaped like a peach, this strange fruit is also the legendary immortal tree fruit, as long as you take it, you can increase your longevity. This is a good thing, but Guo Jia has already thought about life and death, what is the point of living for a long time in this world without the Internet and no food?

But the three elders insisted that he take it to his face, he could only be forced to obey, he casually put the whole immortal fruit into his mouth, chewed a few mouthfuls expressionlessly, and suddenly his expression changed greatly! This longevity fruit was unexpectedly sweet and delicious, fresh and tender, juicy, he had never eaten such a delicious fruit, he couldn't help but taste the residual fragrance in his mouth, looking at Guo Jia's gluttonous look, the three elders all nodded with deep understanding.

Not long after the elder, Guo Jia began to have frequent adverse reactions such as diarrhea and skin pus, which lasted for three days and three nights. The three elders left him in Penglai Xianju, except for three meals a day and sleeping, Guo Jia spent every day in the thatched house and bath room, and he ran to the village elder more than once and pointed at him angrily: "Did you poison me!" Not! You wait for me! ”

However, every time he didn't wait for him to finish complaining, he couldn't help but go to the toilet again, basically every half an hour he had to go to the toilet, and he was about to collapse after pulling, and the elders explained to him: "This is a normal reaction." ”

Three days later, Guo Jia dragged his thinner body down the mountain, and before leaving, the three elders also told him to eat more fish and meat to supplement his nutrition during this time, Guo Jia glared back at them with loveless eyes, and walked down the mountain like a walking corpse.

However, after this toss, Guo Jia had the desire to live again, because on the second day after taking the Immortal Fruit, his omniscient system returned! Not only that, but the omniscient system has undergone a new change, and he turns on the omniscient system again on the way down the mountain. Guo Jia's eyes suddenly popped up a lot of large and small virtual boxes, marked with the names of all kinds of things in his field of vision and brief information, the border in the upper right corner has a magnifying symbol□, a zooming out symbol—and a closing symbol×, and then there is an ellipsis at the end of the brief information, and you can see more information after clicking on it.

Although it is very convenient to look at things from this peculiar perspective, it always feels very awkward, just when Guo Jia was thinking about whether there was a way to cancel this perspective setting, the option box of "whether to change the system settings" automatically popped up in front of him, Guo Jia nodded in surprise, and then this option box immediately dissipated, replaced by a nine-row setting option:

Information concretization, ☑ path navigation diagram□ high-energy early warning ☑, three-dimensional mimic image□ omniscient cloud speed information processing□ the first stage of all-round co-modulation□ the second stage of all-round co-modulation□ the third stage of all-round co-modulation□ all selected □

In the spirit of curiosity, Guo Jia ticked the box of all selections with his mind, and suddenly heard a prompt sound from the top of his head, and an Arabic numeral 1 appeared, and then returned to 0, an irresistible tiredness brought Guo Jia to sleep, and in this short second, Guo Jia's brain completed a huge amount of information analysis at an astonishing speed, and came to the conclusion: excessive mental power consumption→ excessive burden on Zhihai→ causing ability side effects to sleep, sleep time is 71 hours, 59 minutes and 36 seconds.

Guo Jia, who was asleep, rolled directly down the mountain road.
