"Is that so? It sounds quite similar to what I remember." Jiang Ling muttered, then looked around. Seeing that no one was around, she decided to get straight to the point. "Instructor Wang, when does my special training start?"

"Oh, don't worry, don't worry, we have already arranged everything for you... Please follow me!"

Jiang Ling followed Wang Wuji to another exit. With him leading the way, the maze-like area gradually widened. At the end of the passageway was a spherical space, somewhat reminiscent of the cadet training room in "Ender's Game." The sphere was approximately 600 meters in diameter, and at its center, a light source emitted a soft white glow, illuminating the entire sphere. According to Wang Wuji, there were several other similar spaces to Training Room 3. They were originally warehouses on the mothership for storing liquid water. The excess water now served as an ice shield at the front, freeing up space for the training of reserve recruits. These had undergone several renovations, significantly improving their functionality and safety. Besides the required monthly maintenance, they provided continuous training time.

Jiang Ling noticed that there were some tall pillars standing outside the training room. Judging from their size, they looked a bit like the cables used to simulate gravity sections, except that they were now painted yellow and black. Perhaps they were different uses of the same thing.

Training Room 3 was now naturally operational. After adjusting to the brightness of the lighting, she saw groups of military trainees scattered throughout the spherical space. Most of them huddled in the unsupported space, aided by people in different colored clothing to change their flight patterns or alter their trajectory.

"Look!" Wang Wuji pointed to one of the spots. "They're doing gravity adaptation training!"

"Do people today still need to adapt to gravity?" Jiang Ling looked in the direction of his finger and saw several people tied to some fitness equipment with elastic ropes and doing squats.

"Of course. Whether we're in zero-gravity or overweight, we need sufficient training to ensure we don't injure ourselves. I'm a conservative. Rather than letting these kids directly acquire knowledge through TCM, I prefer to let their bodies develop muscle memory. Have you seen the ones I brought you here? They're among my most talented students."

"Uh..." His last sentence was difficult for Jiang Ling to respond to, so she could only use a long silence to get rid of it.

Fortunately, Wang Wuji simply assumed she didn't know enough to comment, and quickly continued the conversation. "I never underestimate any technology that's been passed down from ancient times to the present day, even if it seems insignificant most of the time—like what they're doing right now."

"Useless?"

"Yes, once they get on the spaceship, especially the battleship, they will find that most of what they have learned is useless." Wang Wuji nodded.

"But why do I hear that the current space army is very pragmatic?"

"That's just in terms of resource utilization." He paused, lowering his voice. "That's not what I said. Some experts believe our technological development has entered a period of stagnation. Technological breakthroughs over the past five thousand years have been less than one-tenth of what they were before. Military technology is now as advanced as civilian technology, and this is reflected in every aspect. Specifically, take what you saw before you came here. Think about it, I can't say much more."

"I know - like a printer." Jiang Ling thought thoughtfully.

"Yes, who would have thought that the printers used by ordinary people are essentially the same as those used by the military, the only difference being that some of the blueprints and consumables are kept secret. If they can produce food, they can certainly produce weapons as well. Given enough materials, they could even make the most advanced warships."
