Looking at the inconspicuous wooden box in front of him, Ming Jiutian's heart was also full of anticipation, not knowing what he would leave for himself in his previous life, thinking of this, Ming Jiutian took out the key and prepared to insert it into the keyhole.

"Wait..."The sudden voice directly frightened Ming Jiutian's spirit.

"I said, old man of the black pot, can you say hello in advance next time you come out again?" Ming Jiutian patted his chest.

"This thing inside is extraordinary, it's better for you to go back to your little box and open it" This time Grandpa Black Cauldron did not appear, but used a sound transmission.

Ming Jiutian nodded when he heard this, and walked into the Ten Thousand Realms Spirit Box with the quaint wooden box.

After getting ready, Ming Jiutian took out the two-in-one bronze key again and inserted it towards the keyhole on the box.

With a soft click, a crack opened in the box, and a light blue glow shot out directly from the gap.

Soon the dazzling light gradually dissipated, Ming Jiutian hurriedly looked towards the box, under this look, he couldn't help but be a little dumbfounded, only to see that the inside of the box was still a box, fortunately the box inside was not locked.

"What kind of joke is this life playing? There is a box in the box, is it still a box if you open it again? ”

Ming Jiutian has a black line, such an alternative storage method, it is estimated that only the previous life can think of it.

"Sure enough, this box is not a box, but a piece of sky," said Grandpa Black Cauldron with squinted eyes.

What's in the box? What kind of logic is this? Shouldn't it be a small world like the Ten Thousand Worlds Spirit Box?

"So it's the same as the Ten Thousand Worlds Spirit Box?" Ming Jiutian blinked his eyes, and he didn't quite understand the intention of giving him this thing in his previous life.

"Definitely... No..., the piece of heaven in this is different from the Ten Thousand Realms Spirit Box, to be exact, it should be called the reversal of time and space," Grandpa Black Cauldron said with an unfathomable expression.

Reversing time and space?

Hearing Grandpa Black Cauldron's words, Ming Jiutian's eyes widened, his understanding of time and space has always been in operation, whether it is time or space, it is impossible to stay in a fixed stage and stagnate.

"Reversing time and space is a big joke, isn't it? Those who can reverse the river are the masters of the masters, is it too much to blow the cowhide" No matter how Ming Jiutian thought about it, he felt that it was a little unlikely.

"The name of this thing is called the Time and Space Treasure Box, as for how far it can be reversed, it depends on the user's ability, boy, the universe is completely beyond your imagination, and there is of course more than one person who can reverse time and space," Grandpa Black Cauldron explained seriously.

The fact of reversing time and space is too ethereal, but with Ming Jiutian's understanding, Grandpa Black Cauldron is by no means a person who is untargeted, since he can say so, it means that he must have seen it.

"So what can this thing be used for? Can you let me go back in time? Ming Jiutian asked tentatively.

"Of course not, traveling back to the past through time and space relies on personal strength, not a specific magic weapon, but although this space-time treasure box can't take you back to the past, it can control the speed of time inside, do you understand?" Grandpa Black Cauldron smiled and explained again.

A box that can control the flow of time, isn't it? Thinking of this, the shock in Ming Jiutian's heart was not attached.

"According to what you say, if you control the time inside to three times that of the outside, and cultivate inside, wouldn't the progress of cultivation be three times faster than on the outside?" At this time, Ming Jiutian's heart was excited, and he had an urge to jump out.

"Yes, it can indeed be understood in this way, which is also the reason why you are here to open, but although things are good, they must also be done in moderation, and over-reliance is not a good thing, especially time control, don't be too fast, remember" Grandpa Black Cauldron told affectionately and seriously.

Ming Jiutian can't wait to go in and try it now, if it is really as Grandpa Black Cauldron said, then this thing will definitely become the hottest thing in the Supreme Region.

When the time comes, the husband is innocent and guilty, and it is better not to let too many people know about it for the sake of safety.

For Ming Jiutian, whether the thing is good or not, you can only know if you try it, thinking of this, Ming Jiutian opened the space-time treasure box.

The entrance is a staircase that extends downward, not very deep, and you can see a stone door at the end of the staircase.

But the problem also comes, the box is not big, and the stairs are even smaller and pitiful, and it is not as big as a foot in Ming Jiutian in comparison, how can this be entered?

Ming Jiutian stretched out a foot and carefully tested it, and as soon as he stepped in, a strange scene happened.

I saw that my feet were indeed on the stairs, and the stairs in front of me were no different from the actual stairs.

The eyes look small, but after stepping on it, they become bigger, what kind of trick is this? Ming Jiutian glanced back, and was stunned again at this look.

I saw that the black pot grandfather behind him turned into a giant, standing there looking at Ming Jiutian with a smile, and then looking at the surrounding scenery, a carrot was much bigger than Ming Jiutian.

Seeing this scene, Ming Jiutian understood, they became bigger, but they became smaller, it was really magical, thinking about this, Ming Jiutian said secretly.

I walked down the stairs in front of me, and after a while, I came to the end, gently patted the stone door in front of me, and was slightly cold and did not know the illusion, with full of doubts, Ming Jiutian pushed open the door of the stone room.

Suddenly, an extremely dazzling white light shot out from the stone gate, and Ming Jiutian, who was stabbed, couldn't open his eyes, and it took him a while to get used to it, and Ming Jiutian was able to adapt to the white light in front of him.

At this time, the white light dissipated, but there was another scene in front of me, which actually turned into a vast cosmic starry sky, with stars shining brightly, not a meteor shower, no matter how you look at it, it doesn't look like a fake.

After looking carefully for a long time, Ming Jiutian finally found an open space in this starry sky, and the empty space floating in this starry sky was very conspicuous.

After muttering for a long time, Ming Jiutian took a step towards the floating clearing.

After stepping on the clearing, Ming Jiutian looked around, and this floating clearing was only half the size of a room, and there was nothing except for a dent.

Ming Jiutian squatted in front of the dent, reached out and touched the dent, and found that his hands were stained with some white powder.

After careful identification in Ming Jiutian, it was found that there was an extremely thin aura contained in these powders, which was difficult to find without careful inspection.

Seeing this, Ming Jiutian seemed to understand, took out a high-grade spirit stone and put it in this dent, and a shocking scene appeared.

The originally unremarkable floating space suddenly lit up, and the lines emitting blue light began to move slowly.

In a moment, they were connected together, forming a pair of bagua-shaped pictures and texts with sophisticated identities.

As soon as this bagua-shaped picture and text appeared, the surrounding space immediately began to stir, and a large area of aura quickly formed.

It seemed to sense the change of formation on this gossip diagram, and the meteors in the starry sky quickly crossed the void.

Seeing this, Ming Jiutian hurriedly sat cross-legged, silently casting a chaotic decision, and suddenly the nine suns were suspended above the void, and quickly rotated up, frantically absorbing the aura gathered in the space.

Feeling the aura of heaven and earth that was famously absorbed, Ming Jiutian was surprised in his heart, and at the same time, he smiled from ear to ear, and after a while, the spirit stone in front of him was consumed and turned into a piece of white powder.

Seeing this, Ming Jiu completely understood, and immediately took out hundreds of high-grade spirit stones again without hesitation, placed them in the dents, and continued to start the journey of crazy cultivation.
