Both time-traveled characters ended up as villainous henchmen.

At first, Izumi Nen couldn't understand the reason behind this, but soon he sensed the subtle reason for the enhancement of his own lightning release.

The formation of lightning phenomena is inseparable from the action of positively and negatively charged particles.

The positive and negative electrons, one positive and one negative, perfectly embody the principles of Yin and Yang.

Thunder is the pivotal mechanism of the changes in Yin and Yang in Heaven and Earth.

It is not surprising that his lightning release technique was enhanced due to the initial successful fusion of his Yin-Yang Release technique within him.

What concerned Izumi Nen even more was that his Purple Nether Eyes had also been enhanced through the fusion of the Immortal Technique Yin-Yang Escape.

He has now acquired an offensive Lightning Release eye technique.

Amaterasu thunder escape version.

"Those eyes are so captivating..."

After silently complaining to himself, Izumi Nen couldn't help but show a hint of joy on his face.

The further enhancement of his eye technique was indeed beyond his expectations, and when combined with the strengthened Lightning Release, its effects could be even stronger.

He could even use his pupil technique to control lightning to conceal his true special abilities.

"First it was Yin Lightning Release, and then the Yin Release eye technique that was successfully tested was also related to lightning control, which seems very reasonable."

Izumi Nen stroked his chin and muttered to himself.

He has not yet informed Orochimaru of the success of the Yin Release eye technique. Besides keeping it a secret as usual, the main reason is that only he can successfully master the current version of the Yin Release eye technique's sealing technique.

He still has a lot of work to do to develop a sealing technique that other ninjas with Yin Release chakra can also learn.

Not long ago, he wandered around Konoha Village, collecting relevant data on other people in preparation for this.

We need to give Orochimaru and the Third Hokage an explanation.

Moreover, doing this is also to solidify his genius persona, so that people will believe even more outrageous things he does in the future.

After quickly cleaning up the traces left inside the cave, Izumi Nen dived into the deep pool to prepare to leave.

As soon as he entered the water, his immortal body's efficiency in absorbing natural energy increased significantly, and his sense of control over liquid matter also rapidly intensified.

In an instant, he seemed to have completely merged with the water, becoming one with it.

The entire waterfall and deep pool were no longer just an extension of his perception, but had truly become a part of his body that he could control.

Even just by soaking in the water, he could feel the exhaustion and fatigue he had accumulated over the past two days of cultivation rapidly fading away.

Even the Yin Release chakra within his body was slowly increasing.

Furthermore, he can now move freely in the water for extended periods without having to strain his breath or mobilize his chakra.

In his eyes, this body of water was no longer just a stream of water, but had been transformed by his Sage Body into something akin to Water Release chakra, which could provide him with simple healing and chakra recovery, and even become part of his attacks, without consuming his own chakra.

Of course, without using chakra, he can only mobilize a limited amount of natural water, roughly the size of an ordinary water barrier.

Its defensive capabilities are also inferior to the Ninja Technique Water Formation Wall.

To achieve higher levels of application, the existence of chakra is indispensable.

Nevertheless, Izumi Nen still held extremely high expectations for this special water control ability.

Once the stats are stacked up in the later stages, it becomes a god-tier skill.

After discovering the special connection between his immortal body and the natural water, Izumi Nen was in no hurry to leave the pool. Instead, he stayed in the pool to experience the changes in his immortal body more deeply.

A moment later, Izumi Nen formed a hand seal, ceasing to absorb natural energy from the water, and instead began to slowly adjust the position of his dantian using the Yin-Yang Sealing Technique.

This caused the large amount of Yin-Yang Release chakra gathered in the sealed space to slowly flow into his meridian system and acupoints according to the path of the sealing technique.

At the same time, special facial patterns appeared on Izumi Nen's face, and his pupils also transformed into a shape resembling a yin-yang symbol.

Sage Mode, activated!

Because of the Yin-Yang Seal, Izumi Nen's Sage Mode is different from ordinary Sage Mode. He does not need to refine Sage Chakra in advance. As long as he opens the Yin-Yang Seal and lets the Sage Yin-Yang Release Chakra flow out, he can naturally enter Sage Mode.

Therefore, he basically doesn't have a five-minute Sage Mode time limit. How long he can use Sage Mode depends solely on the amount of Sage Chakra within the Yin-Yang Seal.

However, the power of his Sage Mode is not as great as that of Naruto and Jiraiya in the original work.

The root cause is that his chakra reserves are insufficient to support high-intensity battles; he needs more time to accumulate them.

After activating Sage Mode, Izumi changed his hand seals again, and a large amount of Sage Chakra surged into the natural waters outside his body under his control.

The next moment, an unprecedented sense of powerful control filled Izumi Nen's heart.

Almost instantly, all the waters within the entire training ground, whether connected to this deep pool and waterfall or not, were brought under Izumi Nen's control.

Immediately afterwards, the natural energy in the entire training ground began to be spontaneously absorbed by the waters controlled by Izumi Nen, eventually flowing slowly towards him.

Aquatic Cultivation Amplification Technique!

However, the efficiency is not high at present. Apart from replenishing the consumption of his own Sage Art Yin Yang Release Chakra, it is about 30% better than his idle training.

Moreover, he could clearly sense that it wouldn't be long before he absorbed all the natural energy in this training ground. If he wanted to continue cultivating like this, he would need to give the training ground time to regenerate natural energy.

At the same time, the locations and general situations of the other genin in the training ground were also clearly displayed in his mind.

The wounded, the dead, those in the midst of battle, and those ambushed—there was something for everyone.

He even "saw" two Uchiha acquaintances who were located outside the central tower of the training ground, seemingly lying in ambush for others.

Deep down, Izumi Nen had a feeling that these two were lying in ambush on him, intending to avenge the disrespect he had received outside the training ground.

"Perfect timing. I thought I'd missed it because I was too busy cultivating, but I didn't expect them to wait for me."

A smile appeared on Izumi Nen's face. Even though it was only at the level of a one-tomoe Sharingan, it was still an awakened Sharingan.

With a thought, Izumi stopped absorbing natural energy from the waters of the training ground and voluntarily interrupted his cultivation, leaving the pool completely.

The natural energy in the training ground is less valuable than the Sharingan right in front of you.

After stepping back onto land and getting a feel for the direction, Izumi Nen strolled leisurely toward the tower in the center of the training ground.

Meanwhile, in a deserted grove near the Uchiha clan's territory in Konoha Village, a pale-skinned, humanoid creature that did not resemble a normal human silently emerged from a tree.

His expression was blank, showing no emotion whatsoever. He simply turned his head and stared blankly toward the training ground where the Chunin Exams were taking place.

He sensed it; a special power suddenly surged forth there, drawing him in.

Almost instinctively, he disappeared into the trees again and silently moved toward the training ground.
