After the Council meeting, Eren realized that he needed to become stronger if he was going to protect the blood users in the city. He decided to focus on training his blood affinity, which was his greatest weapon in the fight against the Blood Hunters.
He sought out a renowned blood user, Master Zhang, who had a reputation for training the strongest blood users in the city. Eren was surprised to find that Master Zhang was an older man with a gentle demeanor, but he quickly realized that the master's training was anything but gentle.
For weeks, Eren underwent grueling training sessions with Master Zhang, pushing his body and his blood affinity to their limits. He learned to control his blood more precisely, creating new techniques and attacks that he could use in battle.
But his training was not without setbacks. Eren often struggled to control his blood, and he sometimes found himself on the verge of losing control completely. He also struggled with self-doubt and fear, wondering if he was really strong enough to face the Blood Hunters.
One day, Master Zhang announced that it was time for Eren to face his greatest trial yet: a battle against another strong blood user. Eren was nervous but determined to prove himself.
The battle was intense, with both Eren and his opponent using their blood affinities to their fullest. But in the end, Eren emerged victorious, with his opponent lying defeated on the ground.
Eren felt a surge of pride and confidence as he realized how far he had come. He knew that he still had much to learn, but he also knew that he was ready to face whatever challenges lay ahead. He left Master Zhang's training grounds feeling stronger and more focused than ever before.
