As night fell, Xiang Fan, exhausted, returned to his courtyard. Today, after being "enlightened" by Chu Yang in his mecha class, he'd managed to win a match in the arena, and even been dragged to a celebration banquet where he drank half a cup of spirit fruit wine. By the time he got home, he felt like a completely different person, a mecha with depleted spiritual energy.

He walked to the center of the courtyard. The old, nearly falling apart basic mecha still stood there quietly, like an old friend waiting silently. Xiang Fan sighed and climbed into the cockpit skillfully. "Alas, the road to immortality is long, and so is charging this mecha."

He sat down cross-legged, took a deep breath, placed his hand on the input port of the energy core, and began to transfer spiritual power to the mecha. As the spiritual power flowed into the core, the spiritual energy lines inside the mecha glowed slightly, like a dry well that finally got water.

After more than ten minutes, Xiang Fan was already panting. He withdrew his hand and slumped in the cockpit, muttering to himself, "1% a day! At this rate, by the time I fully charge my mech, I might have already reached Foundation Establishment..." He didn't notice that the mech's energy reserve bar had increased by a small bar today—1.3%, a full 0.3% more than usual.

The psychic patterns within the mecha's core actually repaired themselves slightly after this input, as if they were extremely "satisfied" with the spiritual power. Unfortunately, Xiang Fan didn't even take a closer look. He climbed out of the cockpit, walked back to his room with unsteady steps, and fell asleep.

The next morning, Xiang Fan mingled with the disciples in the sword-training arena of the Dharma Hall, diligently practicing the basic moves of the Lingxiao Sword Technique with his wooden sword. As he swung his sword, he silently chanted the formula: "Wind Slash, Cloud Return, Star Chaser..."

Suddenly, he realized that today's sword practice was particularly smooth. Not only were his movements fluid, but his spiritual energy consumption was much less than usual. He used to be out of breath after swinging a dozen times, but today, after swinging over twenty times, he still felt unsatisfied.

"Strange, why do I feel that my sword skills are so easy today?" Xiang Fan stopped, looked down at his hands, and waved the sword a few more times, and found that his whole body's spiritual power flowed unusually smoothly.

He frowned and thought for a moment, then suddenly raised his head with confidence: "It must be because I practiced a lot! As expected, practice makes perfect. I've finally gotten the hang of it!"

The disciples beside him were sweating profusely while practicing, but Xiang Fan was practicing even more vigorously. He hadn't noticed that his Dantian spiritual energy reserve had quietly broken through the fifth level of Qi training, and he was still immersed in the beautiful misunderstanding that "practice more, practice right."

Elder Chuanfa walked by the sidelines and saw Xiang Fan's effortless sword moves. The corner of his mouth curled up slightly, "Hmm? This kid is in good shape today. It seems he's not completely hopeless." Then he muttered to himself, "But don't be too happy too soon. Maybe he just felt better for a day."

Xiang Fan was overjoyed when he heard the elder's comments. As he swung his sword, he thought to himself, "Sure enough, the elders have finally noticed my hard work! This is the result of my hard work. Haha, God rewards hard work!"

However, he was completely unaware that the circulation of his spiritual power had entered a whole new realm. Even the aura of each sword revealed a hint of the sharpness of the fifth level of Qi training.

The old mecha stood quietly in the center of the yard, and the psychic energy fluctuations in its core became increasingly stable, as if some unknown changes were brewing.

In the communication channel of the Spirit Realm battlefield, Shadow Killer's private message suddenly popped up: "Boss, did you figure out what was in the treasure chest last time?"

Xiang Fan was about to take a sip of tea when he was startled by the news and nearly choked. He quickly opened his storage space and pulled out the long-forgotten blueprint.

The blueprint was a thin, shimmering sheet of metal, its surface depicting a complex circuit diagram in strange runes. In the center, a line of cryptic text read: "Energy Core: Psionic Superconducting Model (Initial Concept)."

Xiang Fan scratched his head and muttered, "I don't understand. It looks like the design of an energy core, but who wrote these runes? Was it drawn intentionally to look like a heavenly scripture?"

He placed the metal sheet on the holographic projection table, and the diagram immediately levitated, revealing complex psychic circuits in the air. The runes seemed chaotic, but upon closer inspection, they revealed a mind-numbingly precise logic.

Xiang Fan stared at the projected image and frowned. "This design is even more mysterious than the spiritual pattern array in the Sutra Library. Could it be the legendary god-level mecha core?"

The Shadow Killer's avatar popped up, his tone full of ridicule: "Boss, this picture looks like a relic of an ancient immortal. Maybe it can be exchanged for a spirit stone mine!"

The Xuanwu guard scratched his head and said naively, "Whether it's for the immortals or not, let's keep it for now. What if it really is a great treasure?"

Ling Ruoxi sneered: "You people always have wild thoughts. Maybe this is just an unfinished design draft."

Shadow Killer quickly added: "Scrap? Do you think the boss would pick up scraps so easily? Are you doubting the boss's judgment by saying this?"

Ling Ruoxi glanced at the Shadow Killer and said without showing any weakness: "I just doubt your IQ."

Xiang Fan couldn't help but smile. He took the metal piece off the projection table and carefully stored it in the storage space. "Whatever it is, it's obviously not simple. Don't tell anyone else yet. We can study it later when we have the chance."

The Shadow Killer patted his chest and said solemnly, "Boss, don't worry! My mouth is tighter than the gate of the Spirit Realm Battlefield!"

Then, he smiled wickedly again: "But to be honest, you're not afraid of being robbed if you tell others, are you?"

Xiang Fan's eyes twitched. "Shadow Killer, don't think I don't know about the time you showed off your Golden Core Thruster and got beaten up!"

The protagonists' communication channel was filled with laughter as they discussed the possible uses of the blueprint, but Xiang Fan's heart remained in suspense. He had a vague feeling that this blueprint was not as simple as it seemed and might cause an unexpected storm.
