As night fell, the night sky was full of stars, and a bright moon hung in the sky, but the light in this ravine was still very weak, and the visibility under the dense canopy was only a few meters away.

Under a concave cliff, four people sat on the ground and shared some dry food.

These dry rations were all stocks in the Mahtab's backpack, which was not much, and the four of them did not have a penny.

Tomorrow's three meals have to find a way to solve.

However, it is not a problem, there are some wild fruits to pick and eat in the mountains, and there are freshwater fish in the creek to catch and eat.

After eating some dry food, Li Zi'an got up and said, "I'll go to the cliff to take a look, you stay down here, don't leave, you can be seen from above outside the door, don't worry about anything." ”

Ciro said, "Don't worry, boss, I'm here." ”

Li Zi'an nodded.

"How soon will you be back?" said Mahtab, worried.

Li Zi'an smiled at her: "I'll be back soon." ”

He grabbed his backpack and climbed up with the claws of the flying tiger instead of going around the hillside next to the cliff. The cliff dozens of meters high took less than two minutes from the time he took out the tiger's claws to the time he climbed up.

Makhtab stared at the cliff with a blank eye, and did not withdraw his gaze until he could no longer see Li Zi'an's figure, and then looked at the hillside next to the cliff.

The slope next to the cliff is not steep and there are many trees growing with some vines entwined in the branches. If you want to climb a cliff, those vines are a great tool.

She really wanted to follow up to see what Li Zi'an wanted to do, but she felt that it was too obvious to follow up like this, especially since her father was still watching from the side.

She secretly said in her heart: "When my dad is asleep, I will climb up and see what he is doing." ”

A smile tugged at the corner of the Persian girl's mouth.

Wit.

At the top of the cliff is a small flat land, and the source of the stream in the ravine is at the end of the flat land, where there is a spring, which washes day and night, and a large chunk of the sediment around the spring is washed away, forming a spring pool.

The water in the spring pool is crystal clear, and you can clearly see the sand and stones at the bottom of the pool, and some of the sand and stones with heavy quartz composition sparkle in the moonlight, which is very beautiful.

There is a large tree on the edge of the platform, more than ten meters high, and a huge canopy covers the flat ground. Standing at the foot of the tree, you don't have to worry about being photographed by satellites and drones in the sky, and no one disturbs you, the place is really good.

Li Zi'an took off his backpack, found a place to sit at the foot of the tree, and then opened the backpack and took out the Book of Heaven.

The so-called book of heaven is really like a laptop.

It may not be called that, the system of the road company calls the fire a ghost, and the name of the book of heaven may also be the name of the system of the road company. Take it back and show it to Aunt Da Yue'er, she may give a different title.

But it doesn't matter, even if it's called Okamoto, it doesn't affect anything, doesn't it?

Li Zi'an reached into the collar of the undershirt and took out the fabric that was attached to his chest.

For him, the fabric is the best collection, he only needs a little minimum connection, and the fabric will be attached to his skin, which others will not see, and it will be bulletproof and stab-proof.

The light at the foot of the tree was dim, but it didn't affect his vision at all, and the seventh celestial map in that ancient tomb showed signs of lighting, and his eyes only needed a little bit of True Qi to see normally in the completely lightless environment of the underground tomb.

When the book of heaven and the fabric are put together, there is no connection between the two things.

But the last time consciousness was pushed to the walls of medieval Jerusalem, he was puzzled by the indispensable role that fabric played.

Li Zi'an stretched out his hand and lifted the "display screen" of the Book of Heaven, as if his shadow was cast on the mirror surface of Mo Cui, a cloud of black shuttles, which was shaped like a mushroom.

There are 108 heavenly inscriptions on the "keyboard", and Li Zi'an knows 66 of them.

If these 108 Heavenly Inscriptions are really keyboards, knowing 66 of them will make do with something. But this was not the case, he knew what the 66 heavenly inscriptions meant, but he couldn't use them to knock out anything.

He stretched out his hand and pressed an inscription of the sky, the inscription of the sky represents a bunch of meanings, if it is explained in Chinese, it should be "thunder", and there are more words that can be composed of it, there are thunder and lightning, thunder people, mines, grenades or something. However, it cannot be understood in this way, in the world of the inscription of the sky, it represents the energy of thunder and lightning and some energy substances related to it, and has nothing to do with grenades, mines, thunder people or anything.

The inscription of the sky representing "thunder" did not sink because of his fingers, although it bubbled up a little like a keycap, but there was no device such as a red shaft or a tea shaft underneath it, and it was cast in one with the book of heaven.

Li Zi'an moved his finger to the keycap representing "yin", as in the case of "thunder", this is only the result of understanding from the perspective of Chinese, it has nothing to do with cloudy sky, cloud, yin X or anything, it represents the related dark matter and energy.

Fingertips swiped the inscriptions of the heavens one by one, and Li Zi'an also had an idea in his heart: "It is wrong for me to understand the inscriptions of the heavens from the perspective of Chinese, these inscriptions of the heavens represent different substances and energies, which are not available in many worlds." If you look at it from the perspective of matter and energy, I think it may be...... Periodic Table!"

It's a fanciful idea.

"No, they represent matter and energy, they are symbols of matter and its energy, edit different matter and energy, and you can produce ...... What ...... "produces", Li Zi'an does not have a specific concept in his mind.

No matter how close to the truth is speculation, it is nothing more than speculation after all.

He tried to inject a trace of chaotic energy into a celestial inscription representing "yin".

Suddenly, a cold sensation came up from his fingertips, down his arm to the Great Lazy Stove, and then from the Great Lazy Portable Furnace to his eyes. At that moment, he felt as if his eyes were frozen, without a trace of temperature, but it did not affect the rotation.

The scenery he saw also changed, it was obviously night, but he saw blue sky and white clouds, and sunshine.

What's going on?

Crash!

Suddenly there was the sound of water behind him.

Li Zi'an hurriedly turned around, and when he saw it, he was stunned.

A young couple with blond hair and blue eyes are playing in the water in that pool.

The blonde and blue-eyed white couple, both dressed in leather clothes, watered each other with their hands. The woman was quickly defeated, turned away, and dodged the water that her boyfriend poured on her face.

The young man took the opportunity to hug her from behind.

The distance between the two was almost one meter before, and in the blink of an eye, it became a distance of minus 0.12 meters.

The "frozen" eye actually has its own eye effect, otherwise it would not be possible to measure this distance accurate to centimeters.

The young couple indulged in love, not noticing that there was a handsome man staring at them at the foot of the tree.

Li Zi'an's eyes moved to the side of the spring pool, and he saw the clothes of the young couple, which were not ancient clothes, they were tight-fitting onesies, and the women's clothes were black, which were very similar to the clothes worn by the female investigators he was familiar with. The man's jumpsuit was silver, and he was familiar with it, similar to the Ultraman battle suit he had seen as a child.

Li Zi'an's heart was shocked and confused: "Could it be that my consciousness has been pushed to historical time and space by the Book of Heaven again?"

Bang Bang Bang!

A wild duck flew up and flapped its wings a little loudly.

The poor duck was frightened.

The blonde girl was also surprised, and let out a whoop of a whoa.

A bold idea popped into Li Zi'an's mind, and his free hand picked up a stone, and then threw it into the spring pool.

The stone drew a parabola in the air and plunged into the pool.

Boom!

There was a sound of water, and a splash of water shot up.

The young couple shook and then disappeared.

The one-piece leather suit of the female investigator next to Izumiike, and the young man's Ultraman battle suit also disappeared.

At that moment, the fingers holding the word "Yin" no longer felt cold, the touch was normal, and the Great Lazy Portable Furnace also cut off the connection with the Book of Heaven, and no longer transmitted chaotic energy.

Everything is back to normal.

The blonde and blue-eyed young couple was still moving in Li Zi'an's mind, and his heart was full of confusion and surprise: "Yin Ji said that the Book of Heaven is a book used by God to record the history of the earth, since it is history, then the scene I saw just now should be the time and space of the past, but judging from the clothes of the young couple, let alone ancient times, even in the past fifty years, there was no such costume, is it ...... Wouldn't it?"

He thought of a possibility.

That's prehistoric civilization!

What he just saw was not the historical scene of modern mankind, but the scene of prehistoric human beings!

Otherwise, how could there be such a costume?

Following this line of thought, a new idea popped up in his mind: "If that couple is a prehistoric human, such a costume, could it be that the prehistoric human is Ultraman Tiga, who makes a living by fighting monsters?" I have seen huge sparrows, and I have also been trampled to death by a seismic dragon weighing more than 100 tons, and the living environment of prehistoric humans is really difficult." ”

Thinking of this, he couldn't help but laugh himself.

The so-called Ultraman is just something from the Toei anime, and the Investigator is also a unique culture over there, where would there be any Ultraman and a female Investigator in prehistoric humans. However, it is certain that the civilization of prehistoric humans is completely different from the civilization of modern humans, otherwise there would be no magical things such as fire and heavenly books.

If you have tried "Yin", what will you see in the inscription of the Heavens that represents "Yang"?

Li Zi'an's finger moved to the inscription of the sky representing "yang", and then pressed it. But before he could inject chaotic energy into the heavenly inscription, there was a rustling sound on the side of the cliff. He hurriedly raised his finger, closed the book of heaven, and then looked away.

In the hazy moonlight, a familiar figure came into his sight.

That's Mahtab.

The Persian girl was grasping a vine and climbing up the cliff with little difficulty and care.

Li Zi moved with peace of mind.

She's ......

Did you bring him a snack?
