Chapter 2

Today is Thursday, and although the air is thick with PM2.5, Tianming feels that the weather is particularly good.

In the morning, after completing his resignation procedures, Tianming had an 88 yuan seafood pizza near Tianmu Street, and instantly felt much more satisfied with life.

Apart from a personal computer and a cup, Tianming's backpack contained no extra items. He got on his electric scooter and wobbled his way home.

Lying comfortably on the bed, Tianming groaned, "Ah, the feeling of freedom is great."

With a casual wave of his hand, a football-sized hole appeared in the air, dark and deep. Tianming extended one hand into it and casually took out a bottle of Sprite.

With a "hiss," he opened the bottle cap, gulped down a mouthful, and said, "With the ability to open a spatial dimension, life is endlessly enjoyable!"

"The outdoor adventure equipment I bought from Taobao should be arriving soon!"

For safety reasons, Tianming did not rashly open the spatial portal of the cube, even though he could control the diameter of the portal and could directly enter the small space through it. However, he didn't do so, fearing that the environment inside might be different from Earth's or that there might be terrifying creatures inside. Entering rashly would be like playing with his life.

……

"Mr. Xu, you have a package."

The delivery efficiency of Taobao was still quite high. Just three days after placing the order, things started arriving one after another.

150 meters of 5mm nylon rope, a wilderness backpack, a Swiss Army knife, a flashlight, a breathing apparatus, an oxygen tank, and waterproof protective clothing, along with pulley ropes.

These items were carefully selected, and Xu Tianming spent over 10,000 yuan on them from Taobao.

Looking at the pile of items in the living room, Tianming smiled, "Finally, everything is ready. The plan can begin."

Before this, Tianming also went to the Nanhua Street pet market and bought a long-eared rabbit.

Of course, buying the rabbit wasn't for keeping it as a pet. Keeping a pet is a hassle, as they eat and defecate randomly and like to jump onto your bed to urinate and defecate. Tianming had already been made quite miserable by the rabbit named "Huihui."

The rabbit was called Huihui because most of its fur was gray, which was quite fitting.

Petting the long-eared rabbit in his hand, Tianming said gently, "Huihui, the master has a serious task for you. You must be a good boy and listen!"

Although it couldn't understand human language, Huihui still struggled habitually.

"Chirp, chirp," ignoring the rabbit's struggle, Tianming tied one end of the prepared nylon rope to its two hind legs and the other end to a pillar by the door.

To find a relatively sturdy spot to prevent the rope from coming loose after entering the spatial portal, Tianming threaded the rope through a reserved electrical hole in the wall, around the outside, and finally tied the other end to a concrete wall pillar, looping it several times to ensure it was extremely secure.

Taking out the mysterious cube from the spatial ability, Tianming combined the portal rune "Yuan," and a black vortex appeared on the surface of the cube.

"Open," Tianming lightly commanded. Under his mental control, the black vortex slowly extended and expanded, forming a conical funnel that continued to expand outward.

The bottom of the funnel was the entrance to the spatial portal.

The hissing sound of the airflow, as before when opening the portal, indicated that it was drawing air from the environment to balance the pressure difference between the two spaces.

Tianming had also conducted an experiment, fixing the spatial portal on the cube to a diameter of half a meter, opening the doors and windows, and letting it continuously draw Earth's air. After a day and night, it was like a bottomless pit, with no change in the hissing sound, indicating that the size of the other space was much larger than imagined.

The only certainty was that the small space inside the cube still had atmospheric components. If it were a pure vacuum, the huge pressure difference would have sucked Tianming in, causing his blood to boil and leading to death.

Looking at the 20 cm diameter hole, Tianming nodded.

Grabbing the rabbit, ignoring Huihui's intense struggle, Tianming threw it into the spatial portal.

"Chirp, chirp," Tianming could even hear Huihui's terrified cries from inside the portal.

Due to the airflow, the small long-eared rabbit was blown to the place Tianming wanted it to go: the mysterious space.

The 150-meter rope was quickly more than halfway through the spatial portal, which was longer than Tianming had imagined. "How can it be so fast? Is the rope not enough?"

Fortunately, when only 20 meters of rope remained, the pulling force from the portal finally decreased, indicating that the rabbit had entered the small space.

Tianming secretly rejoiced, "It's working!"

However, to determine the length of the spatial portal, Tianming repeatedly pulled and released the nylon rope, eventually concluding that the portal was about 110 meters long.

"Good, it's about as I imagined. Now, I'll test the survival environment on the other side. Huihui, hold on! If you can survive, the master will treat you well in the future!" After a minute of mourning for the rabbit, Tianming let the rope go all the way.

10 minutes, 20 minutes, 30 minutes, 1 hour later.

Tianming began to pull the rope back, like reeling in a net.

The rabbit was pulled back into the familiar Earth space.

Dead or alive?

The rabbit lying on the floor, like a corpse, showed no signs of breathing. Tianming shook his head, "Ah, Huihui is probably dead."

Wait! Hey, it seems to have moved. Tianming rubbed his eyes, it moved! It really moved.

Seeing the rabbit slowly get up and hop around, Tianming suddenly realized that when he pulled the rope, he did it too quickly. Due to the reverse airflow, Huihui couldn't breathe for a short time, causing it to faint, but it was actually still alive.

The final result showed that the environment in the small space was suitable for Earth creatures to survive!

"Yay! I knew it, the small space must be a good place. But before that, Huihui will have to make a few more sacrifices to help the master explore!"

Thus, within two days, the unfortunate Huihui was thrown into the small space over ten times. It stayed for a total of 26 hours, and the last time it underwent a 12-hour extreme survival test. Despite this, after each test, the long-haired rabbit Huihui returned alive and even more lively, and Tianming noticed that Huihui no longer resisted being thrown into the dark spatial portal.

There's a chance! He can try going inside himself.

Wearing a sealed protective suit, carrying an oxygen tank, wearing an oxygen mask, and attaching a rappelling rope, Tianming carefully opened the spatial portal.

Expanding the portal to about 2 meters in diameter, Tianming, gathering his courage, pulled the rope and entered the dark spatial portal, pushed by the airflow.

It was very dark, and the flashlight could only illuminate about 5 meters ahead, with the light beam being swallowed by the portal.

As he walked, his body felt lighter and lighter, almost floating, but the airflow's push didn't stop him from moving forward.

After about 80 meters, a bright light appeared at the bottom of the portal, indicating the entrance!

Continuing forward, a suction force almost made Tianming lose his grip on the rope and fall.

Looking ahead, what kind of world was this?

Blue sky and white clouds, a clear sky, and a gentle breeze.

A lush green meadow, towering trees. In the distance, mountains, valleys, and lakes reflecting light. Even the sound of flowing water could be heard, clear and pleasant, like the sound of a guzheng and a chorus of drums.

At this moment, Tianming realized he was about 500 meters above the ground in the small space. The gravitational pull was dangerous, and although he didn't know the exact gravity, the force on his waist indicated that falling would be catastrophic.

Ignoring the surrounding scenery, Tianming quickly exited the small space.

After several back-and-forth trips, Tianming finally found a solution.

The spatial portal could be moved, but only from the outside. Based on the positions he marked during his observations in the small space, Tianming moved the portal rune to the lower right corner of the cube's sky face. Here, there was a hill with an altitude of nearly 500 meters and a gentle slope. Tianming decided to use this as the landing point to enter the small space.

Letting go of the rope, "Ha!" standing on solid ground, Tianming experienced the environment of the small space for the first time.

The long-eared rabbit Huihui in his arms seemed to enjoy the air and sunlight here.

Tianming tried to open the oxygen mask.

A gurgling sound came from his lungs, no good.

Taking out a pressure gauge, he saw that the atmospheric pressure was only 2/3 of that on Earth's plains, explaining the pressure difference.

Putting Huihui on the ground, it ran around happily, already adapted to the environment.

Although he was sure there was no risk, Tianming still brought some physical and chemical measuring instruments to measure the environment of the small space. "Gravity 6.83 m/s², temperature 25.2°C, oxygen content 27%, atmospheric pressure 0.067 Mpa, humidity 55%, PM2.5 content close to 0... all indicators are close to or exceed the optimal human survival conditions."

The fact that Huihui was lively and the lush meadows and forests in the small space indicated that the lower atmospheric pressure could be adapted to with some time.

Thus, Tianming put down his protective suit and oxygen tank, held the oxygen mask, took a breath of the air in the small space, then switched to a breath of pure oxygen from the tank, and slowly expelled the excess gas from his body...
