Eren's arrival at Levi's base was met with a stark contrast to the training camp he had just left. The facility was more austere, a reflection of the disciplined and no-nonsense approach of Levi and his squad. The base was surrounded by high walls and located in a remote area, isolated from the usual hustle and bustle of the military's main operations.

The base itself was simple, with functional and minimalist design. It was clear that the focus here was on efficiency and effectiveness rather than comfort. As Eren stepped inside, he was greeted by the sight of Squad Levi going about their routines—each member moving with the precision and skill that marked their reputation.

Levi led Eren through the base, explaining the layout and introducing him to the key areas: the training grounds, the mess hall, and the living quarters. The base had a serious, almost clinical atmosphere, which was a far cry from the more communal and less structured environment of the training camp.

"This is where you'll be living and training for the next year," Levi said, his tone as direct as ever. "The conditions here are tough, but that's part of what you'll need to get used to. Training under me is not a luxury."

Eren nodded, absorbing the information. "I understand. I'm ready to start."

Levi's eyes narrowed slightly. "We'll see about that. We start early tomorrow. Get some rest tonight, because you're going to need it."

Eren settled into his new quarters, a modest room with just the basics—bed, desk, and a small window overlooking the training grounds. It was a stark contrast to the more comfortable accommodations he was used to, but he was determined not to let it affect him.

That night, as he lay in bed, Eren couldn't help but feel a mix of excitement and apprehension. The prospect of training with Levi was both thrilling and daunting. He knew that the next year would be one of the most challenging periods of his life, but he was eager to prove himself.

Morning came quickly, and Eren found himself up before dawn, ready to face his first day of training. The base was already alive with activity as Levi and his squad prepared for the day. Eren joined them in the mess hall, where a quick, no-nonsense breakfast was served.

"Today's focus will be on conditioning and basic combat drills," Levi announced as they finished their meal. "We need to see where you're at and what needs improvement. Be prepared to push your limits."

The training grounds were designed for maximum efficiency, with various stations for different exercises. Eren was introduced to a series of grueling drills, including endurance runs, strength training, and advanced ODM gear maneuvers.

At first, Eren found himself struggling to keep up with the pace. The intensity of the exercises was far beyond anything he had experienced at the training camp. Levi's standards were exceptionally high, and every mistake or lapse in focus was met with a stern correction.

Eren pushed through the fatigue, driven by his determination to succeed. Each drill tested his physical and mental limits, but he refused to let his resolve waver. Levi's watchful eye followed him closely, providing feedback and pushing him to improve.

By midday, Eren was exhausted but resolute. He had already learned that Levi's training was not just about physical prowess; it was about mental toughness and the ability to endure and adapt.

During a brief break, Eren sat with his fellow recruits, who had also been assigned to train with Levi. They shared stories of their experiences and offered encouragement.

"Don't get discouraged," one of the recruits said. "Levi's training is brutal, but it's meant to push us beyond our limits. You'll get used to it."

Another added, "Just keep pushing forward. It gets better with time, and the results are worth it."

Eren appreciated the words of encouragement, finding solace in the camaraderie of his fellow trainees. He knew that the road ahead would be long and difficult, but he felt a sense of solidarity with those who were on the same journey.

As the day drew to a close, Eren was weary but satisfied with his progress. He had endured the first day of training and learned more about his own limits than he ever thought possible.

That evening, as Eren rested in his quarters, he reflected on the day's challenges. Despite the exhaustion, he felt a deep sense of accomplishment. The training was tough, but it was exactly what he needed to grow stronger.

Levi's approach to training was unforgiving, but Eren understood that it was a necessary part of his development. He was determined to embrace the challenges and emerge from this year of training as a more capable and formidable soldier.

As he prepared for bed, Eren's thoughts were filled with a renewed sense of purpose. The path ahead was demanding, but he was ready to face it head-on. With each day, he would push himself further, learning and growing under Levi's tutelage.

Eren knew that the journey would be arduous, but he was ready to endure and rise to the challenge. The year of training with Captain Levi was just beginning, and he was determined to make the most of every moment.
