Both time-traveled characters ended up as villainous henchmen.

With just a slight sense, Izumi Nen knew the approximate abilities of Izumi Nen's still incomplete eye technique bloodline.

Because he possesses two bloodline limits related to Yin Release, namely Yin Lightning and Dark Water, his eye technique bloodline limit, which evolved from Yin Release chakra, is also inextricably linked to Yin Lightning and Dark Water.

The most direct ability of his eye technique bloodline is to greatly enhance his control over the Yin Lightning and Dark Water bloodlines, as well as the efficiency of his chakra utilization for both bloodlines.

In short, he can now use one unit of Yin Lightning and Dark Water bloodline chakra to achieve the same effect that originally required four units of chakra.

Based on this, the basic abilities of the Yin Lightning and Dark Water bloodlines have almost quadrupled.

His abilities in controlling water, lightning, and blood have also improved significantly compared to before.

Now he can not only erode and control liquid substances in nature as his own sensory tentacles, but also control lightning that erodes nature to a certain extent.

At first glance, this lightning control capability seems somewhat useless because thunderstorms are not common.

However, the natural lightning he can control refers to more than just lightning as a weather phenomenon.

Static electricity generated by friction, as well as broader electrical phenomena such as electrical facilities (such as various electrical appliances and even power transmission equipment like utility poles), are also within his purview.

In other words, the scope of his sensory and reconnaissance capabilities suddenly expanded from various liquids to electronic devices.

Their methods are more diverse and harder to counter.

Izumi Nen also vaguely sensed that he seemed to have developed an extraordinary talent for computer programming.

"Is this another manifestation of Agu Nen and the Sword & Skull Nen...?"

Izumi Nen twitched the corner of his mouth and thought to himself.

However, electronic programming doesn't seem to fit the current style of the ninja world.

The ninja world is still a supernatural world dominated by chakra. Izumi Nen's ability to control electronic devices adds to his capabilities, but it is far from powerful.

When facing powerful Lightning Release ninjas, his control over lightning would be greatly reduced.

The reason is simple: the lightning release technique used by the ninja contains a large amount of other people's chakra.

The presence of other people's chakra will greatly weaken Izumi Nen's control over external lightning.

Similarly, this phenomenon also appeared in the Netherworld Water Yin Escape technique; he could not control the blood of others remotely as easily as he could control the blood in his own body.

To control another person's blood, he needs to inject his own Yin Release Chakra into that person's body.

Now that things have come to this point, if there are simpler and more direct ways to kill the enemy, and if illusions are to control them, then illusions should be even more convenient.

However, this reminded Izumi Nen of another bloodline clan with dojutsu in the Naruto world, the Blood Pond Clan.

This clan's bloodline technique, the Blood Dragon Eye, not only possesses extremely powerful illusion abilities but also strong blood control capabilities, and can even turn those they control into human bombs.

Its practical effectiveness is much stronger than the Dark Water Yin Release that Izumi Nen figured out on his own.

"Perhaps I can explore the Blood Pool Clan in the future."

Izumi Nen silently thought that if the acquisition of the Sharingan continued to be blocked, the Blood Dragon Eye of the Blood Pond Clan seemed to be an alternative.

Of course, the Sharingan is still the best choice, after all, it is the bloodline left by the Sage of Six Paths, and it can eventually evolve into the Rinnegan.

The Otsutsuki clan is the true answer in the ninja world.

After suppressing her thoughts, Izumi Nen slowly activated her newly formed pupils and looked at her own body.

With his powerful control over lightning and liquids, he also gained a special "X-ray vision".

He can clearly see the direction of blood flow in the body, as well as the weak electrical signals transmitted between nerves.

Using this ability, he can also cast illusions through his pupils, a type of illusion that targets the blood flow and nerve signal transmission in another person's body.

Of course, this illusion technique requires his eye technique bloodline to be fully evolved before he can use it, and the consumption seems to be quite high.

"As expected, it still can't compare to the Sharingan's mastery of genjutsu."

Despite knowing the result, Izumi Nen was not too disappointed.

He can make up for and evolve his missing illusion abilities in the future using the Sharingan, so there's no need to worry too much about temporary gains or losses now.

Moreover, his resistance to illusions has been greatly enhanced.

Feeling the unique perspective of dark red in his eyes, Izumi Nen got up and walked around the training room.

"His field of vision has expanded to a certain extent, and his dynamic vision has also been enhanced to a certain extent. Once the evolution is complete, he will be roughly at the level of the two-tomoe Sharingan in this aspect."

After a brief trial, Izumi Nen deactivated the eye technique.

His eye technique bloodline has not yet fully evolved, and excessive use of it will only slow down his evolution.

"Next, we'll see what Orochimaru and the Third Hokage's attitude is towards the spiritual energy sealing technique."

Izumi Nen smiled slightly, cleaned the training room with Water Release, and then left.

Over the past week, Orochimaru has provided significant assistance to his research on sealing techniques.

They even proactively improved several sealing techniques for him.

It was precisely because of this that he was able to quickly complete the sealing technique for spiritual energy and rapidly expand it to the sealing of Yin Release chakra.

However, he did not let Orochimaru know about the latter immediately.

He simply handed over the complete sealing technique for spiritual energy and the cultivation process to Orochimaru.

He also mentioned the need for higher-level sealing techniques, such as the Four Symbols Seal, to support his next stage of research.

Orochimaru was astonished and incredulous at the result, but soon he realized what was going on and headed straight for the Hokage Building with the scroll containing the spiritual energy sealing technique.

"I will give this scroll to the Hokage, and I will also bring back the advanced sealing techniques you requested."

Before leaving, Orochimaru smiled and gave Izumi Nen some instructions.

As a result, Izumi Nen was temporarily given some free time to cultivate.

He did not waste his talent. Instead, taking advantage of Orochimaru's increased trust in his abilities, he entered the underground training room and began training in the Yin Release Chakra Sealing Technique, which he had been preparing for a long time.

And the result was exactly as Izumi Nen had predicted.

He succeeded.

He succeeded on his first try, without having to expend any extra effort on trial and error; his mastery of the Yin Release Chakra Sealing Technique was achieved in one step.

Perhaps it was Orochimaru's "belief" that had the effect, and maybe there was also some help from the Third Hokage, Hiruzen Sarutobi.

Izumi Nen wasn't entirely clear on this, but during his cultivation, he did feel that he was in excellent condition, his mind was very active, and his luck was quite good.

He even finished his cultivation an hour earlier than he had planned.

"Next, we just need to wait for Orochimaru to bring back the Four Symbols Seal, so that we can move on to the next stage: sealing the body's energy and the Yang Release technique."

A flash of lightning appeared in Izumi Nenyu's purple eyes, his face full of anticipation.
