The game starts with escaping from the famine and flipping the table

Yu Shuheng and the other three passed through the third and fourth levels one after another like a gust of wind, and their control over the avenues of time and space became increasingly perfect.

In the mysterious space, Su Xiaoya couldn't hold back her curiosity and asked, "Jinlong, did you move the 'Mobius Strip' and the 'Klein Bottle' here?"

The 'Klein bottle' and the 'Mobius strip' are like twin brothers.

The "Mobius strip" can be understood as a long and wide strip of paper. After rotating one end of the strip 180 degrees, it is pasted to the other end to form a loop. In this way, every point on the strip will be rotated, thus forming one-sidedness.

Of course, during the production process, one end of the paper tape can be rotated 180 degrees, or 540 degrees, 900 degrees, or other odd multiples of 180 degrees...

The Möbius strip has only one face and one border. Its image is like an elongated Arabic numeral "8", like an endless snake, winding and twisting...

If you put a bug on the "Mobius strip", it can reach any other point on the paper from any point without crossing the edge. After crawling around the strip, the bug will be surprised to find that the direction of rotation is completely opposite to what it originally knew. It is as if it is trapped in an endless maze, and can never reach the end, but also seems to keep returning to the starting point...

The "Mobius strip" is a magical topological figure. It is like a mysterious magician, demonstrating some amazing properties in topology, such as the magical charm that remains unchanged after the figure is bent, enlarged, shrunk or arbitrarily deformed.

The "Klein bottle" is a geometric body obtained by cleverly applying the principle of the "Möbius strip" to three-dimensional figures.

The "Klein bottle" is a dreamland with no distinction between inside and outside. It cannot be created in the three-dimensional world. It is a strange surface that can only truly show its charm in four-dimensional space.

The mysterious space where Su Xiaoya is located is a bit like being in a four-dimensional space, and each level set by the "Shang Bronze Sacred Tree" is equivalent to each independent three-dimensional space.

This allowed Su Xiaoya to verify all the rules of time and space that she had previously comprehended from the perspective of a bystander...

Su Xiaoya looked at Jin Long, whose emotions had calmed down, and a smile appeared in her eyes. This gift was quite valuable.

Su Xiaoya blinked her eyes and couldn't help asking the system: "Yiyiyi, do you still have the Ten Thousand Year Soul Nurturing Wood to exchange?"

"Yes, host!" The system was as reliable as ever, and immediately gave the answer: "However, the effect of the Ten Thousand Year Soul Nurturing Tree is not as good as the 'Bronze Mirror' that the Golden Dragon is currently borrowing. It is recommended that the host exchange it for a 'Soul Nurturing Pearl'."

Well!

Su Xiaoya's heart was up and down, like a roller coaster. Although the process was a little tortuous, the result was excellent.

The "Soul-Nourishing Bead" that the system recommends, apart from other things, its soul-nourishing effect is definitely stronger than the bronze mirror that the golden dragon currently resides in.

"Exchange!" So Su Xiaoya agreed to the exchange without any hesitation.

"Okay, host! Exchange for a 'Soul-Nourishing Bead' and deduct points." The system completed the exchange quickly without hesitation, and then, like a caring mentor, explained to Su Xiaoya in detail the specific effects of the "Soul-Nourishing Bead".

The "Soul Nourishing Bead" has five magical effects: nourishing the soul, improving the soul realm, assisting soul cultivation, storing soul information, and enhancing the power of the soul.

Nourishing the Soul: It is like injecting the source of life into the soul, revitalizing it and enhancing its stability. It is like covering the soul with an indestructible shield to prevent the soul from dissipating or being damaged.

Improve the realm of the soul: It is like paving a road to a higher level for practitioners, helping them to improve the realm and level of the soul, thereby enhancing their own strength and practice results.

Assisting soul cultivation: Just like a golden key to open the treasure house of cultivation, during the cultivation process, the soul-nourishing beads can play an auxiliary role of adding the finishing touch, helping practitioners to better perceive the spiritual energy of heaven and earth, absorb energy, and improve the efficiency and success rate of cultivation.

Storing soul information: It is like a mysterious treasure house that can hold soul memories, emotions, consciousness and other information, providing a safe place for the soul to reside.

Enhance the power of the soul: For those creatures who use the power of the soul as the main method of cultivation, the soul-nourishing bead is like a vast ocean, which can enhance their power of the soul, allowing them to destroy all obstacles like a tsunami in battle.

After listening to the introduction of the system, Su Xiaoya was overjoyed, and a soul-nourishing bead emitting a soft light appeared in her hand.

She carefully handed the Soul Nurturing Orb to the Golden Dragon, as if she was holding the most precious treasure in the world. The Golden Dragon's eyes were fixed on the Soul Nurturing Orb, and a hint of surprise flashed in his eyes. The light was like a bright star in the night sky, instantly igniting his hope.

Without the slightest hesitation, the golden dragon turned into a dazzling golden light and penetrated into the soul-nourishing bead like lightning. In an instant, the light of the soul-nourishing bead suddenly burst out, as dazzling as the scorching sun in the sky. There was a faint sound of a dragon's roar, and the sound was deafening, as if it was going to break through the clouds.

Uh!

Su Xiaoya was stunned by this sudden change. This, this is too exaggerated, right?

It was not the first time that Su Xiaoya came into contact with a residual soul, but the Golden Dragon’s was the most exaggerated.

Su Xiaoya's pair of big, Caroline-like eyes were wide open, which almost made Lao Bai lose his concentration, but he still forced himself to suppress his smile and tried to show a resentful look.

snort!

A crying child has milk.

Don't think you don't know, this fellow has a lot of good things in his hands. But I can't let myself, the "Qingyuan Star No. 3 Tool Man", be forgotten because of Jinlong's joining.

Cough cough!

Thinking of the title "Qingyuan Star No. 3 Tool Man", Lao Bai almost broke down again. This was a nickname that Su Xiaoya gave to them, the time travelers, as a joke.

At this moment, Su Xiaoya finally felt someone staring at her, and that gaze seemed to carry endless grievances.

She couldn't help but turn her head and met Lao Bai's dark, aggrieved eyes. Lao Bai's eyes narrowed slightly, and there seemed to be a hint of - resentment?

"Cough cough!"

Su Xiaoya almost choked to death on her own saliva. She blinked her eyes, her heart full of confusion. She really couldn't understand why Lao Bai was crazy again.

Obviously, Lao Bai didn't need to nourish his soul bead. His soul was becoming more solid day by day and was already strong enough. But why did Lao Bai look at her like that?

She observed Lao Bai carefully and found that his body was trembling slightly, as if he was trying to restrain some emotion. Su Xiaoya couldn't help rolling her eyes. What's the big deal?

Seriously speaking, Lao Bai is the type who would rather just lay back and enjoy his retirement, so why did he start to make progress as soon as Jin Long appeared?

Cough cough!

Seeing that Lao Bai was still looking at her with resentful eyes, Su Xiaoya felt helpless. She decided not to guess Lao Bai's thoughts anymore, but to focus on the soul-nourishing bead in front of her.

After all, Lao Bai has made a contract with himself, and his soul is becoming more solid than the girl's, so it is only a matter of time before he reunites with his physical body.

At present, the changes in the Golden Dragon are what need attention.

After all, it was Su Xiaoya’s first time using the soul-nourishing bead.

At the same time, Yu Shuheng and four others also successfully passed the fifth level.

Their figures instantly returned to the World Tree Ladder. If they had not clearly felt the improvement in their own strength, they would definitely think that what just happened was just a dream.
