Kamui Dimension

"Okay, Dad!"

As soon as 9527 finished speaking, the Mangekyō Sharingan in his inventory turned into a streak of golden light and merged into Lin Yu's body.

The moment the golden light entered his body, Lin Yu suddenly felt a warm current surge into his eyes.

After a while, as the warm current faded, Lin Yu suddenly sensed a vague connection. Following that feeling, he naturally activated a certain ability.

"Kamui!"

Lin Yu's body twisted for a moment before vanishing from where he stood.

Lin Yu only felt his vision go dark. Then he found himself in an unfamiliar space that stretched as far as the eye could see, filled with countless massive stone pillars crisscrossing one another.

Lin Yu stood atop one of the enormous stone pillars, curiously surveying his surroundings.

"So this is the Kamui Dimension! It's a little desolate!"

"Dad, this space is your private dimension. Only your eyes can enter it, and your eyes can automatically memorize coordinates in the real world. By locking onto those coordinates, you can emerge from the Kamui Dimension anywhere."

"Can I pass through secret realms?"

"You can, but it requires a lot of spiritual power. Your current spiritual power isn't enough, Dad. You should first check your spiritual power!"

After hearing 9527's words, Lin Yu carefully sensed the spiritual power within his body and found that he had only a little over half remaining.

Ever since Lin Yu had unlocked Wood Release, both his total spiritual power and recovery speed had far surpassed those of ordinary people due to Wood Release. He hadn't expected a single use of Kamui to consume half his spiritual power!

"So with my current strength, I can only use Kamui twice? Then I should have a total of half a K worth of spiritual power, right?"

Rubbing his chin, Lin Yu muttered to himself.

"Mm, that's right, Dad! But what's this half a K?"

Keeping up his good habit of asking whenever he didn't understand something, 9527 asked Lin Yu.

"How should I explain it... Hm? Just know that K is a unit of measurement!"

Lin Yu waved his hand, with no intention of explaining further. Since he was already in the Kamui Dimension, he decided to use all the things he had just looted here.

"9527, use everything we looted!"

"Okay, Dad!"

As soon as 9527 finished speaking, Lin Yu felt countless memories flood into his mind. In an instant, he completely mastered the Rasengan and perfect Sage Mode.

Following the new method that had appeared in his memories, Lin Yu curled his five fingers slightly, and a pale blue sphere of spiritual power roughly ten centimeters wide instantly appeared in his hand. The spiritual power inside the sphere spun at high speed, visible to the naked eye.

Lin Yu looked at the Rasengan in his palm and slammed it hard against the stone pillar.

"Boom!"

With a thunderous roar, a deep pit about one meter wide appeared in the stone pillar. Lin Yu looked at the effect caused by the Rasengan and nodded in satisfaction.

Although the Rasengan was not as powerful as Lin Yu's other abilities, he was very satisfied with its lack of cooldown and rapid formation speed.

Moreover, the Rasengan could be said to be the most malleable skill. All sorts of strange attributes could be fused into it. The young lord had practically kneaded the Rasengan into every possible form.

After testing the Rasengan, Lin Yu once again circulated his spiritual power according to the Sage Mode method from his memories. In an instant, the spiritual power in his body began racing through specific meridians, and the distinctive eye markings of Sage Mode appeared around his eyes.

"This is...?"

Lin Yu froze. Didn't it require natural energy? He had only tried it casually, so how had he activated it directly?

"9527, what's going on?"

Lin Yu asked 9527 in confusion.

"Dad, after inheriting Wood Release, your constitution actually changed. Though it isn't as powerful as a Sage Body, you can still absorb natural energy. In other words, the spiritual power in your body already contains natural energy."

"Huh?! If that's the case, wouldn't a Sage Body be useless to me?"

"You can't put it that way, Dad. A Sage Body won't just raise your constitution to another level; its recovery speed is dozens of times faster than your current one. Even the boost from Sage Mode will increase accordingly. Otherwise, how could it count as an SSS-rank talent?"

9527's explanation enlightened Lin Yu. He had thought the Sage Body would be useless to him, but he hadn't expected such a massive difference!

Lin Yu gauged his current strength and directly formed a Rasengan. A sphere of spiritual power nearly thirty centimeters in diameter appeared in his hand.

Looking at the Rasengan in his hand, which used about the same amount of spiritual power as before but was three times larger, Lin Yu smashed it hard into the ground. A deep pit roughly three meters in diameter appeared before him.

"This power has been enhanced by at least three times!"

Lin Yu's eyes lit up, and he nodded in satisfaction.

Then Lin Yu deactivated Sage Mode. In less than a minute, one-fifth of the spiritual power in his body had already been consumed. In other words, even at his peak, Lin Yu could only maintain Sage Mode for less than five minutes—and that didn't even include the spiritual power consumed by his other abilities. By that calculation, when fighting at full strength, Lin Yu could maintain Sage Mode for at most one or two minutes.

"I'm still too weak!"

Lin Yu sighed. Fortunately, he was the only one in the Kamui Dimension, and 9527 was the only one who could hear him. Otherwise, jealous people would probably beat him to death for being so ungrateful despite his good fortune.

"Oh, right, 9527, where's my Monkey Demon King? This is the first time I've looted a living creature!"

"Dad, just use the Rinnegan's Summoning Jutsu. The system has already modified it into a Rinnegan summon for you.!!"

"Good son, that's thoughtful!"

"No big deal. Choose the 9527-brand system—Dad, you're worth it!!"

Even without seeing it, Lin Yu could picture what 9527 looked like right now. That kid's tail was definitely raised to the heavens.

"Then I just need to use Summoning Jutsu directly?"

"Yes, Dad."

Lin Yu didn't waste any words. Although he now had Kamui, it still wasn't enough to save Ji Xuejun. There was a delay when using Kamui to bring someone along. Though the dual Mangekyō Sharingan made Kamui extremely fast, that slight delay could be a fatal flaw against an eighth-rank Guardian like Sikong Luohe.

As for Lin Yu's other divine skill, the Flying Thunder God Technique, it was useful but required a mark. He couldn't even get close to the battlefield right now, so Flying Raijin was effectively restricted as well.

Thus, Lin Yu still needed a way to hold Sikong Luohe back. Now, he could only hope that the Monkey Demon King would come through.

"Summoning Jutsu!"

Lin Yu suddenly felt the spiritual power in his body flow at an incredible speed into the rune formed by the Summoning Jutsu. His expression changed, and he frantically cursed 9527 in his heart. Damn it, it consumed so much and it hadn't told him beforehand. At least it should have let him take a Soldier Rations Pill first.

Just as Lin Yu felt like he was about to be drained dry, the spiritual power finally stopped flowing away. A cloud of white smoke appeared before him. Seeing that the summoning had succeeded, Lin Yu hurriedly took out a Soldier Rations Pill and swallowed it. Only then did he relax.

"9527, are you trying to replace your dad? You didn't even remind me. You nearly got me killed."

"Sorry, Dad. I forgot."

9527 said pitifully.

"..."

Lin Yu was speechless at 9527's excuse. He no longer had the strength to complain about it and could only sigh helplessly. Oh well, it was his own system, after all!

Lin Yu didn't continue chatting nonsense with 9527. He focused his eyes on the white smoke that was about to disperse.

"Master!"
