Sky Curtain: With a vermilion mirror, Jing travels through the modern world, shaking all dynasties.

"Nonsense! I'd be happy if you could just leave me alone!" Jiang Chuan stubbornly turned his face away, but his ears were secretly turning red.

Zhu Jingjing's eyes darted around, and she leaned closer with a sly look. "Brother, if you're willing to tell me where you're taking me tomorrow, I'll reluctantly stay with you a little longer, how about it?"

Jiang Chuan rolled his eyes at her, annoyed. "Where else can we go? The gym! If you don't exercise more, you'll become a little fatso sooner or later!"

As soon as she finished speaking, Zhu Jingjing proudly lifted the hem of her shirt, revealing her flat and toned stomach. "I won't gain weight! Don't believe me? Look!"

"Put your clothes down right now!" Jiang Chuan abruptly turned his head, his voice tinged with panic. "You're not allowed to show your belly to anyone else in the future!"

Zhu Jingjing paused for a moment, then tilted her head, her eyes full of mischief. "Brother, are you shy?"

Jiang Chuan reached out and straightened her head, saying, "How many times have I told you not to tilt your head? Why don't you ever learn!"

After saying this, Jiang Chuan turned and left. As he closed the door, he heard the little princess excitedly exclaim, "Brother is really shy! He actually changed the subject!"

The next day, at the gym.

"Brother, this lump of iron is so heavy, I can't lift it."

As soon as she entered the gym, Zhu Jingjing set her sights on the pair of pink dumbbells. She held them up for a long time, her face turning red, but she couldn't lift them more than a few times.

"That's ten kilograms, of course you can't lift it." Jiang Chuan, who was doing warm-up exercises, couldn't help but complain, "Start with two kilograms first, don't try to challenge yourself with something too difficult right away."

"Two kilograms? That's like a toy!" Zhu Jingjing muttered unconvinced, but still obediently switched to smaller dumbbells.

She'd only lifted it twice when she spotted the treadmill next to her, her eyes lighting up: "Brother, I don't want to do this anymore! What's that machine? It looks so interesting!"

Jiang Chuan explained, "This is called a treadmill. I'll buy one online and put it at home so you can exercise without leaving the house."

Zhu Jingjing was taken aback by his words and asked suspiciously, "Running at home? How big is that house? You'd run into the wall after just a couple of steps, wouldn't you?"

Jiang Chuan strolled over to the treadmill, casually patted the handrail, and said, "As long as this thing is here, this isn't a problem!"

Zhu Jingjing pouted, looked the machine up and down, and muttered, "This metal frame doesn't even look as big as my bed. There's not enough room to lie down, let alone run!"

Jiang Chuan chuckled and said, "Don't underestimate it! This thing is a master at 'drawing a circle on the ground'; no matter how hard you run, you'll never escape its grasp and will be firmly trapped on it!"

"Brother, you're just bragging!" Zhu Jingjing's face clearly showed disbelief. She strode onto the treadmill, hands on her hips, and challenged, "Then try letting it trap me!"

"Then hold on tight, be careful not to fall!" Jiang Chuan reminded him before pressing the switch.

Three Kingdoms, new fields.

Upon hearing the saying "drawing a circle on the ground as a prison," Liu Bei asked Zhuge Liang, "Strategist, what kind of technique is this? Could it be the legendary art of shrinking the distance?"

Zhuge Liang gently waved his feather fan, smiled slightly, and said, "Why do you say that, my lord? How can there be a way to shrink the distance between places? This is just a trick to deceive the enemy."

Liu Bei cupped his hands and said, "I would like to hear the details."

Zhuge Liang replied, "I have thought about this. If we were to dispatch three armies, all dressed in identical attire, to take advantage of the fog and appear in different directions around the enemy lines, they would be unable to catch us no matter how hard they tried. They would surely suspect it was the work of gods or ghosts, or even the ability to shrink distances."

modern.

Following Jiang Chuan's instructions, Zhu Jingjing gripped the handrails tightly with both hands, ready to go.

Jiang Chuan lightly pressed the start button and whispered, "It's starting. If you can't hold on, you'd better tell me right away!"

As soon as he finished speaking, the tracks beneath his feet began to slowly move.

The sudden movement startled Zhu Jingjing, who gasped and instinctively took hurried steps, afraid of being thrown off.

After calming down and regaining her composure, she finally had the strength to speak, her little face full of smugness: "Brother, you underestimate me! You think you can trap me with this?"

Jiang Chuan's lips curled into a mischievous smile as he hovered his finger over the accelerator button: "Then you'd better hold on tight, I'm going to speed up."

As the fingertip pressed down, the speed of the tracks suddenly increased.

Zhu Jingjing's originally relaxed steps instantly became chaotic. She bit her lip tightly and had to do her best to increase the frequency of her leg swings.

A moment later, her breathing became rapid, and fine beads of sweat appeared on her forehead.

Jiang Chuan reacted quickly and slammed the emergency stop button.

The tracks screeched to a halt due to inertia; had it been ten seconds later, the little princess would likely have landed face-first on the spot.

"How was it?" Jiang Chuan looked at her with a half-smile. "How was the feeling of being 'trapped in a circle'?"

Zhu Jingjing, her face flushed, gripped the armrest. "This thing is really amazing! I wish we could get one for Father too, so he could exercise while reviewing memorials and stop complaining about backaches all the time!"

Jiang Chuan was ashamed; this little princess was probably a devil!

Imagine the majestic Hongwu Emperor, sweating profusely on a rapidly spinning treadmill, his hand trembling as he scribbles red ink with a vermilion brush.

The scene was so beautiful, he almost couldn't bear to look!

The scene was so beautiful, he almost couldn't bear to look!

Three Kingdoms, new fields.

Looking up at the sky, Liu Bei exclaimed in astonishment, "Such a wondrous art exists in this world! That little girl has been running as fast as she can, but that 'treadmill' is so strange and unpredictable that it has trapped her in a small space. Though she moves like a rabbit, she hasn't actually made a single step forward!"

Zhuge Liang gently waved his feather fan, pondered for a moment, and then said with piercing eyes, "My lord, you are wise. In my opinion, the principle behind this thing is probably similar to that of an escalator. When one moves, the other moves too, and they move in opposite directions to counteract each other. Therefore, even if you work hard and suffer, you will hardly make any progress."

Upon hearing this, Liu Bei was first taken aback, then clapped his hands in admiration: "Indeed! If you go up the escalator against the current, this is the scene! Brilliant, brilliant!"

Zhuge Liang couldn't help but sigh, his eyes filled with longing: "The people of later generations are truly wise! Not only are their ingenious skills unparalleled throughout history, but their mastery of tools is also profound and unfathomable, leaving people in awe!"

Zhu Jingjing collapsed onto the floor in a "spread-eagle" position, her chest heaving violently. Her sports shirt was already soaked with sweat and clung tightly to her body.

"Brother, Jingjing is really not going to make it anymore. She doesn't even have the strength to move a finger!" She lay on the ground, looking utterly hopeless.

Jiang Chuan gave a helpless wry smile and handed her a bottle of water. "Jingjing, you need to get used to it quickly. You'll have to come at least once a week from now on; it's a mandatory course!"

Upon hearing this, Zhu Jingjing's eyes widened, and she waved her hands in terror, "Brother, please spare me! Your 'torture instruments' from later generations are even more terrifying than the imperial prisons of our Ming Dynasty; they're practically inventing ways to torture people!"

"What nonsense are you talking about? This is called exercising and strengthening your body!" Jiang Chuan reached out and grabbed her arm, pulling her up from the ground like a chick. "Alright, stop being so cheeky. Go take a shower, and I'll take you to the 'Dragon Palace' for some fun later!"
