At dawn, Li Yu was woken up by the wild birds chirping on the branches outside the cave.

After sleeping on the hard ground all night, I inevitably had a sore back. Li Yu woke up, as soon as he regained consciousness, he subconsciously touched his neck, the pendant of the wheel has been tied around his neck, he tore one from the belt, twisted it into a thin rope, and it served as the necklace of the wheel that visitors regarded as treasures in this day.

Li Yu studied it for a while, but he still didn't understand what this thing was for, but he felt hungry in his stomach. In the ninth month of the lunar calendar, the weather has become very cold, and the remaining chicken can not go directly into the stomach, but fortunately, the bonfire has not been completely extinguished, Li Yu filled in some leaves and branches, blew the fire up, heated the chicken and ate his stomach, and hurriedly set out on the journey.

Although he was curious about the chakra, he was penniless and had no dry food, so it was impossible for him to hide in the cave and study it carefully.

Li Yu traveled all the way, trekking through mountains and rivers, hungry to fill his hunger with mountain spring wild fruits, in his memory, there was the original owner of this body hunting skills, Li Yu also gradually recalled, from time to time can also get some game, but lack of salt condiments, mouth is about to fade out of the birds. Only when you go to a crowded place, beg for a bowl of porridge to eat, and spread a layer of pickles on top to taste the salty taste.

In this way, he walked for three days, sometimes over the mountains, sometimes across the river, and met merchants and pedestrians on the same road, and if there were chariots and horses, he could still say a good word to take advantage of the journey, so he went on and on, and in the evening of the third day, Li Yu was by a river, and he used his sharp branches to fork a fat fish to roast to eat, and then he touched the wheel with his greasy hand and began to study.

"The Visitor from Heaven must have an incredible effect on this gadget with such a high level of civilization and so much importance to it. But what exactly does it do? How exactly do you start it? The three-eyed beauty had already given me some permissions. ”

Thinking of the three-eyed alien beauty with a graceful appearance and a different style, Li Yu suddenly thought of the legendary Erlang God Yang Jian, this Yang Jian couldn't be made up by the ancients out of thin air, right? Could it be that the three-eyed people once came to the earth, and because of their incredible power, they were regarded as gods by the earthlings?

Li Yuhuer thought of the saying "one day in the sky, one year on earth", which is also ancient and seems to be an incredible fantasy, but in Einstein's theory of relativity, it is a scientific reality that can be realized. Was this statement of the ancients a whim, or did "someone" tell them so, just like the three-eyed beauty told him?

Li Yu was thinking wildly, and he was still subconsciously playing with the Zeus Wheel Necklace in his hand, when suddenly, his fingers scratched on the openwork metal cover covered with dark blue necklace beads, and a small wound oozed a drop of blood.

Li Yu groaned, and quickly put his fingers in his mouth and sucked. Xiang Shen fell back to his chest and bounced a few times, and the blood stained on the pendant's coat splattered onto the dark blue Xiang Zhu in it. Xiang Zhu immediately underwent a strange change, and the faint blue light suddenly rippled like ripples, and layers of dark blue ripple-like light waves, rippling, getting bigger and bigger, enveloping Li Yu's whole body.

"I see! I see! ”

Li Yu looked at the changes that had occurred in his body in surprise, and suddenly realized. The gene lock is also a rare thing for people in his time, plus when the three-eyed goddess said this, the three-dimensional image fluctuated, Li Yu didn't hear it clearly, thinking about it at the moment, what she wanted to say was to use your blood to open the gene lock.

Li Yu didn't know what kind of ability this celestial wheel would bring to him if he opened the genetic lock, he was nervous and excited, and waited excitedly, until the circle of blue ripples disappeared again, and Li Yu was stunned to find that there was no change in ----!

He's still him, and he's sitting there. The day is still the same day, when it is dusk, the sunset is full of sky. Wrong! There are changes! The clear river in front of him is gone!

Li Yu's face changed, and he jumped up, and the small river in front of him, which was three feet wide but no deeper than his knees, was really gone. He looked around again, and not only was the river gone, but the pebbled ground by the river, the rock he had leaned on, was gone, and he was now in a field of wild grass, half-man tall artemisia grass......

Wait a minute! What is that?

Li Yu looked at the things that appeared in the grass in surprise and walked over step by step.

It was a bonfire, and on it was a simple wooden frame, on which was worn a roasted and oiled hare. How is this scene so familiar?

Li Yu looked at the tooth marks on the hare's body that had been gnawed twice, and suddenly realized, jumped up in surprise, pointed to the bonfire, as if dancing hula: "I understand!" I finally got it! Hahaha! What a treasure this chakra! It turns out that it can reverse time and space! Reverse time and space! It was yesterday! This is where I slept out yesterday evening, hahaha......"

Li Yu was like a madman, jumping happily around the bonfire for a long time. Being able to go back to the past means being able to predict the future, and being able to predict the future means that he can take the lead and walk ahead of everyone. With such a magic weapon, what else can't he do?

But...... When Li Yu was tired of jumping and laughing, and sat down by the campfire, he suddenly realized that in order to have this ability, he still needed to figure out a lot of things:

First, he was going back exactly a day now, twelve hours ago, could he go back to the distant past?

Second, if he can't go back to the more distant past all at once, can he go back day by day?

Third, since he can go back to the past, can he go to the future? So that he can return to his modern world.

Then, Li Yu found that if he wanted to figure out these problems, he needed to keep experimenting and groping, and when he wanted to experiment and grope, he suddenly realized that he had returned to a day ago, that is, he had traveled hard for a day...... It's all gone, and he has to start all over again.

In view of this, Li Yu did not dare to try, at least not for now. He wanted to test whether this thing could go backwards for twelve hours in a row, and he had to wait for him to return to Lizhou, and stay in Lizhou for at least two days before trying, so that he would not take many more unjust roads because of the test.

Thinking that the road he had traveled would have to be walked again tomorrow morning, Li Yu couldn't help but hang his head, because the joy brought by discovering the wonderful effect of the Zeus wheel was much lighter.

Later, he discovered something even more heart-wrenching: the rabbit had been roasted into a black clump......
