This matter was too miraculous, Jiang Xiaobai had countless questions to answer.

But no matter how Jiang Xiaobai tried to control the mouse, he was unable to open up the last game he played, and could no longer find the mysterious old man.

After fighting until around midnight, Jiang Xiaobai had no choice but to give up.

It seemed that if the old man did not appear again, he would have to find a way to use the key in the future.

Although he did not close his eyes for thirty hours, Jiang Xiaobai did not feel the least bit tired.

If you can't sleep in a bed, you might as well go to another world.

Walking to the door, Jiang Xiaobai imagined the appearance of Locust Tree Slope in his mind and gently opened the door.

Immediately, a gust of cold wind blew over.

The quiet Locust Tree Slope lied like a giant on the ground a hundred meters away, the trees on the hillside rustling sounds.

A bright moon hung in the sky, and under the bright moonlight, the small river in front of the mountain was suffused with a rippling light.

It seemed to be midnight?

Time is relative.

Jiang Xiaobai remembered the three sentences the old man said before he left.

That is to say, the time in this space is the same as the time in the space where I lived before?

This was day time, and it would also be day time.

It's winter here, and it's also winter there?

If time corresponds to explain, then what about space corresponds to matter?

Using the powerful light from the flashlight, Jiang Xiaobai measured the boundaries of the spatial barrier once again. It was exactly as the old man had said, with the door as the center, its radius being thirty meters, and its diameter not more than one meter.

Such a boundary happened to be about two meters away from the north side of the road, from the entrance to the vicinity of the Pagoda tree.

Behind the thatched cottage was a vast wasteland. Although there were no tall trees, the wild grass had grown to the height of a person.

While researching the boundaries of the activity, Jiang Xiaobai also discovered a strange phenomenon.

It was a summer and autumn season, and there were a large number of nocturnal insects in the grass. When the powerful light stopped, there would soon be swarms of mosquitoes and moths flying around the light beam.

However, only the mosquitoes and moths within the borders came.

Although the other mosquitoes outside the border also wanted to fly near the light source, they were stopped by an invisible wall. Some were bounced back and some even fell to the ground.

What shocked Jiang Xiaobai even more was that when a bat was charging towards a moth at the border, it actually made a splash of blood on the wall that he couldn't see.

Strange, I can't get out. Could it be that other creatures can't get in?

But a few hours ago, wasn't there a bandit chief who called himself Hei Huer and a big dark horse that came in?

Could this boundary be selective?

Jiang Xiaobai did not understand, hence he did not think about it at all.

The most important thing was to expand his living space in this space-time — to build other Portal of Space-time.

The old man had once said that as long as a door was made of wood or iron, even if it was a piece of cloth or curtain, the key would transform it into a passage that connected the two spaces, allowing the space to expand.

If even a curtain was possible, then what about the fence door?

Try it.

Standing at the starting point, Jiang Xiaobai looked around and quickly decided that the second door would be opened on the east side of the thatched cottage, near the dirt road.

If every Crossing Point really had a radius of thirty meters, this kind of setting, could not only allow Jiang Xiaobai to step onto the dirt road, but also allow him to be less than twenty meters away from the small river in front of him.

With that said and done, Jiang Xiaobai immediately returned to the real world. He found the hoe, sickle, axe and other tools that he used to farm in the past and started to busy himself.

First, he had to clear out the weeds and shrubs, creating a path that led to the gate.

This process lasted about two hours. A path that was about two meters wide and over ten meters long was opened up at the end, right next to the edge of the nodule.

Then there was the door frame, which was very easy, as there were some dried wood left behind by some unknown person in the small courtyard.

Jiang Xiaobai chose two wooden sticks that were relatively straight, and were a little more than two meters long to stick at the end of the road. On top of that, he tied a meter and a half long wooden beam, and a original door frame was completed.

Other than that, Jiang Xiaobai had also planted a dozen or so wooden posts on both sides of the door frame to make a fence wall.

With the door frame and the fence in place, what followed was the most important link — the door.

According to his initial assumption, Jiang Xiaobai had planned to make a door out of the artemisia selengensis that was everywhere.

However, Jiang Xiaobai had overestimated his weaving ability. From the deep night to the late morning, Jiang Xiaobai consecutively created seven so-called doors, but all of them failed.

Some were too heavy to stand on.

Some of the structures were too fragile, just a slight shake and they would fall apart.

It took him great effort to weave a decent piece of work according to the size of the door frame, but he suddenly realized that the door had no open axle at all.

In the end, Jiang Xiaobai had no choice but to return to the real world and take down the curtains in his bedroom.

Since the old man had declared that the curtain could become a Portal of Space-time, then he would test it out with the real curtain.

In order to make this thing more like a door, Jiang Xiaobai had even written the traditional word "door" on it.

Thus, no matter who saw this strange thing, the first thought that would appear in their mind would definitely be the door, right?

Of course, such a door could not immediately become a channel connecting the two dimensions.

According to the old man, the key would take twenty-four hours to store enough energy to create a spacetime tunnel.

This was exactly the case. After Jiang Xiaobai hung the curtain on a few wooden sticks, he lifted the curtain no less than ten times.

The result was exactly as he had expected. The front and back curtains belonged to the same world.

Since the time was not right, he would wait.

From late in the morning to the scorching sun in the sky, and then again the evening sun in the evening.

Jiang Xiaobai anxiously waited while using the tools in his hands to fix up the place. He removed the weeds in the courtyard and tidied up the broken tables and chairs.

He needed to clean up the three thatched cottages as well. Since they were his base of operations for developing in a foreign world, he could not afford to be careless.

One was used as a bedroom, one was used as a living room, and the other was used as a kitchen and storage room.

As Jiang Xiaobai organized his things, he also looked towards the northern hill, feeling very vexed.

A fine horse, at least two hundred catties of meat. Under such high temperatures, it soon stank. What a waste!

If he had known earlier, he would have killed this horse in the yard. That way, he could have eaten free horse meat!

Finally, at the top of the locust tree, Jiang Xiaobai reckoned that it would be at least nine o'clock at night, which was enough for twenty-four hours.

Therefore, Jiang Xiaobai walked to the door and took a deep breath, his mind thinking of passing through space and time, and pulling open the curtain with the word "Door" written in red.

Right at this moment, Jiang Xiaobai felt nothing beneath his feet, and he fell head first into a pitch-black space.
