Kaname Tōsen at a Loss

The days flew by in a blur of experiments and studies.

Zhu Xun's life became extremely regular. During the day, he handled medical affairs in the Fourth Division, and in the evening, he repeatedly deduced the spatial techniques taught by Tessai Tsukabishi in his dormitory.

Occasionally, he would take time to go to the secret chamber of the Kidō Corps to receive personal guidance from the Grand Kidō Master.

Such a high-intensity pace would have exhausted most people, but Wang Xun's learning efficiency, enhanced by the system, far surpasses that of ordinary people.

Every concept that Tessai Tsukabishi taught him was internalized the moment the fragments flooded in.

Those details that require repeated practice to grasp can be accurately replicated with just one demonstration.

From initial shock to subsequent silence, and now to complete acceptance, Tessai Tsukabishi to accept it all.

He has completely accepted this fact.

I'm numb.

You're in good spirits today.

Inside the secret chamber, Tessai Tsukabishi looked at the spatial magic formula drawn by Wang Xun and nodded.

"The precision of this anchoring node is no worse than mine."

Wang Xun did not look up; the Reiatsu at his fingertips continued to trace patterns in the air.

"You flatter me, Great Kidō Daoist Priest. I've just been practicing too much."

Tessai Tsukabishi shook his head and did not reply.

"You've mastered eighty percent of the spatial technique's structure. The rest isn't a technical issue, but rather a matter of the total Reiatsu."

"Your current Reiatsu is insufficient to support the casting of large-scale spatial spells. This is a rigid requirement that cannot be rushed."

Wang Xun laid down the foundation of the technique.

"I understand. So what I can do now is optimize the technique to its limit, and once the Reiatsu rises, everything will fall into place naturally."

Tessai Tsukabishi nodded.

"Speaking of which, is Aizen satisfied with the Garganta proposal you submitted?"

"Not bad."

Tessai Tsukabishi was silent for a moment, then said softly.

"That's good."

The underground cavity of Sōkyoku Hill.

Kisuke Urahara squatted in front of the lab bench, fiddling with a new instrument in his hands, with various parts scattered around him.

He didn't look up when he heard footsteps.

"You've arrived?"

Wang Xun walked to the experimental table, Kisuke Urahara placed the latest plan for opening the Garganta on the table.

"The iterative version, take a look."

Upon hearing this, Wang Xun picked up the document and opened it.

His gaze swept over the dense array of technique nodes, and his brows gradually relaxed.

"Not bad, the Reiatsu transition at this point is much smoother than the previous version."

Wang Xun nodded.

"The previous version's Reiatsu burst was too fast, causing it to misalign with the anchoring position within Hueco Mundo. This optimized version is much better."

Urahara looked up at Wang Xun, a hint of surprise flashing in his eyes.

"You... you can actually understand this?"

"Yes, I sought guidance from the Great Kidō Daoist Priest."

Urahara paused for a moment.

"Tessai Tsukabishi?"

"Right."

Wang Xun did not hide anything.

"He has been studying spatial techniques for many years. I went to him to ask him questions, and he was willing to teach me."

Urahara remained silent for a moment.

Then, a slight smile appeared at the corner of her mouth.

"That old buddy of a man, he's been keeping it well hidden. I thought I was the only one in Soul Society who secretly researched these things, but it turns out he's not exactly honest either."

He put down the documents, leaned against the lab bench, and crossed his arms.

"But if it's him, it's not surprising; you learn very quickly too."

Wang Xun did not respond.

Urahara looked at him, his gaze becoming complicated.

"Wang Xun, I've always been curious, how exactly do you learn? Your learning speed is beyond the realm of ordinary understanding."

Wang Xun thought for a moment.

Urahara looked at him and remained silent for a long time.

Then, he sighed.

"Okay, I'll continue to optimize the Garganta solution for you. Wait for my update."

Wang Xun nodded.

"Good."

A few days later, Aizen stood in front of the experimental table, with Wang Xun's latest Garganta proposal spread out before him.

His gaze fell on the dense array of Reiatsu nodes. Kaname Tōsen stood to the side, his hands hanging at his sides, his expression calm.

"Have you reviewed this plan?"

Aizen asked.

Kaname Tōsen nodded.

"Yes."

What do you think?

Kaname Tōsen was silent for a moment.

"My understanding of spatial techniques is limited, so I dare not make any judgments. However, judging from the completeness of the techniques, Wang Xun's progress is much faster than expected."

Aizen the plan and turned to look at him.

"It's not just much faster, it's faster than expected."

"Yes, you've been with me for so many years, you should know what the Garganta' technique means for our next plan."

Kaname Tōsen lowered his head.

"Understood."

"Therefore, I hope you can fully cooperate with Wang Xun. You can't match his technical skills, but your execution ability is what he needs."

Kaname Tōsen's fingers clenched slightly, then relaxed.

"Yes."

"Go ahead, Wang Xun should be here soon. Go help him prepare for the experiment."

Kaname Tōsen turned and walked towards the door.

He paused slightly as he pushed open the door, let out a deep breath, and strode into the corridor.

Experimental area.

Wang Xun was adjusting the spell, his Reiatsu flowing between the nodes at his fingertips.

When Kaname Tōsen in, he didn't even look up.

"Lord Aizen asked me to help."

Kaname Tōsen's voice was calm, but Wang Xun could detect a hint of unease within it.

"You've come at the right time. Help me check the Reiatsu of node number three; I can't leave here."

Wang Xun said.

Kaname Tōsen walked to the experimental table, picked up the technique base plate, and began to explore.

His Reiatsu probed into the nodes, sensing those complex Reiatsu trajectories.

Then, his brow furrowed.

He couldn't understand the structure of many of the techniques.

It's not that he can't understand it at all, but rather that he can only grasp the surface of many things.

The turning points and timing of those Reiatsu nodes, and the way in which Hollowfication Reiatsu and Soul Reaper techniques were integrated, were all beyond his knowledge.

He gritted his teeth, trying his best to keep up with Wang Xun's train of thought.

Fine beads of sweat appeared on his forehead, but the key points of the techniques remained a jumbled mess in his mind.

Is the Reiatsu at node number three still stable?

Wang Xun's voice came from the center of the experimental area.

Kaname Tōsen was silent for a moment.

"--. I'm still observing."

He wasn't actually sure.

But he couldn't say he didn't understand.

Lord Aizen entrusted him with this task because he trusted him.

If he can't even be Wang Xun's assistant, what will Lord Aizen think of him?

He took a deep breath and continued examining the node.

He had to repeatedly ponder each point before he could even barely understand it.

His head was buzzing, and his Reiatsu was rapidly depleting, but he dared not stop.

"Tōsen, please calibrate node seven for me."

Wang Xun's voice came again.

Kaname Tōsen's fingers paused slightly.

He walked to the location of node number seven and probed in with his Reiatsu.

Those Reiatsu trajectories seemed to him like a tangled ball of threads; he tried to untangle them, but the more he tried, the more chaotic they became.

He put down the base of the technique, breathing heavily.

My mind is a complete blank.

"What's wrong?"

Wang Xun walked over.

Kaname Tōsen raised her head slightly, and Wang Xun's voice was calm.

"It's nothing, just a few things I'm not entirely sure about..."

Wang Xun picked up the technique base plate and gently touched it with his fingertip.

As Reiatsu surged in, those chaotic nodes were instantly straightened out.

After giving a brief explanation, he handed the base plate back to Kaname Tōsen.

"Try again."

Kaname Tōsen over the base plate and probed in with his Reiatsu.

This time, following Wang Xun's instructions, he began to sense the chaotic nodes, and they finally became clearer.

But we are still far from truly understanding.

Kaname Tōsen silent.

When he heard about the Garganta project from Aizen, he thought Wang Xun would be stuck on this technology for a long time.

Spatial techniques are taboo in Soul Society, and there is very little information about them. Even talented people need years or even decades of accumulation to make a breakthrough.

But Wang Xun had only been in charge for a short time...

They started at the same point, and Kaname Tōsen Wang Xun, all to lay the foundation for later experiments.

But at this moment, he couldn't even understand Wang Xun's Kidō technique?

Kaname Tōsen's fingers trembled slightly, and his breathing became increasingly heavy.

My mind was in complete chaos.
