As the spar with Hashirama ended, Seimei's life returned to the usual flow.

He trained hard, attended the Ninja Academy, focused on Shinobi tactics, completed two missions per month to keep up with the mandatory academic schedule, researched new Jutsu, tinkered with new potions, and studied Fuinjutsu seals.

Days turned into weeks, and weeks turned into months. Time flowed like an unrelenting river, and in the blink of an eye, seven more months passed by.

During this period, he also experienced two more significant physical upgrades. All thanks to his consistent efforts during each chakra infusion training session.

The first one enhanced his brain and central nervous system, giving his spirit attributes, thinking speed, bodily coordination, and reflexes a major boost.

His control over his body and his dexterity had never been more perfect. His reflexes had never been more instantaneous. His mind had never been sharper and clearer.

At least, that was how Seimei felt after going through the second major physique enhancement.

Of course, with his spirit attribute soaring a few points, Seimei's chakra control finally broke through to LV7.

He could perform Jutsu faster. The power of his Jutsu or any technique that required chakra increased by several notches.

He could supercharge any Jutsu within a fraction of a second.

These days, Seimei could perform all C and B-rank Jutsu without hand seals.

Even if he learned a new B-rank Jutsu, he could perform it without hand seals after a few tries.

The feeling was indeed exhilarating. Seimei loved it.

As for A-rank Jutsu or higher…

Well, the complicated ones still needed him to perform a few hand seals. Plus, hand seals often helped him control the complicated Ninjutsu better.

However, he could perform and perfectly control the Ninjutsu he invented and trained in relentlessly without hand seals now.

For example, the Chidori Series Ninjutsu, Wind Release: Tearing Beast Fangs, or Earth Release: Chains of Gaia.

He could perfectly cast and control them without hand seals.

This, coupled with his large, growing chakra pool, would be a nightmare for the enemies on the battlefield.

Apart from that, this second round of enhancement also improved his brain activities, intuition, perception, sensory capabilities, thinking speed, pattern recognition skills, tracking skills, and predictive abilities to an insane degree.

Because of that, his proficiency in the Uzumaki Sealing Technique had increased quickly. He reckoned that he would become a Fuinjutsu Grandmaster within one year or so if he kept progressing at this speed.

And that also meant he could finally condense his own unique Flying Thunder God Seal and master the Flying Thunder God Technique, one of the only few combat-oriented space-time Ninjutsu created through sheer technical skills in this world.

Of course, there were other space-time Ninjutsu as well. But most of them were either ocular techniques, bloodline abilities, or advanced techniques from the Otsutsuki or other extraterrestrial clans.

Once he mastered this space-time Ninjutsu, his combat power and survivability would soar to new heights.

He could literally go to the enemy camps, beat the enemy Shinobi black and blue on their own turf, and then retreat in the blink of an eye.

Interesting. Very interesting.

Just the monocle was missing. Otherwise, it would have been perfect.

Anyway, the point was that once Seimei mastered the Flying Thunder God Technique, he would be an absolute menace. His very existence could make it difficult for his enemies to sleep in peace.

After all, he could soundlessly sneak in at any moment and hand them a ticket to the Pure Land.

His father was doing it already. And Seimei could do the same, too.

Hehehehehe…

Seimei had to admit that the result of the second major physique advancement proved to be more profound than the first one.

If the first one gave Seimei a powerful body with enhanced strength, speed, and defense, then the second one provided him with chakra control, thinking ability, perception, and ultra-fast reflexes to fully utilize the strength of his enhanced physical body.

The Senju ancestors definitely knew their stuff. The chakra infusion technique was incredible.

Then, after three more months of chakra infusion training to nourish his viscera or internal organs, he finally finished his third and final major physique enhancement.

And its effect was no less miraculous than the first two major physique enhancements.

After all, this one strengthened his internal organs, including his heart, lungs, liver, stomach, kidneys, pancreas, intestines, thyroids, spleen, and reproductive organs.

His brain also received a second wave of nourishment during this process.

He could now digest most foods quickly and extract almost all the nutrients from them to nourish his body. His digestive system had become so powerful that he could extract nutrients and energy from the foods he ate within minutes.

Now, even if he suffered from malnutrition due to prolonged hunger, he could reach his peak state within hours as long as he ate enough food.

Any excess energy would be stored in his blood and other body parts, making it easier for him to stay at his peak state without food or water for at least a week.

Of course, that was only true if he didn't engage in intense combat and suffer from several injuries. Otherwise, he would still burn through the stored energy to heal his wounds and keep himself at his peak state.

A hidden perk: No matter how much he ate, he would never get fat anymore.

Most girls would kill to get such a gift. Well, except for the Senju girls, because they were already enjoying the benefits of the chakra infusion technique.

Then, he had his enhanced kidneys that could clear impurities from his body and circulatory system more efficiently.

He could no longer get drunk from the alcoholic drinks that could knock other regular Jonins out. He had even gained an enhanced poison resistance as a side effect.

The enzymes his liver produced became more powerful, too.

It gave his overall digestive function, toxin removal, waste removal, energy conversion, and protein production a great boost.

With his enhanced lungs, he could hold his breath longer and absorb more oxygen from the air to boost his physical activities. As a result, his already insane stamina increased once again.

With his enhanced reproductive organs…ahem…let's not talk about this now.

His heart was brimming with vitality. After the third minor physique enhancement, his heart could make his blood carry wisps of Yang Release chakra in it.

The result?

His regenerative abilities had grown by leaps and bounds.

Although his regenerative capabilities were still far from reaching the level of Hashirama, he could indeed heal from deep fleshly wounds within a minute or two.

Wounds that could force others to retreat and lose their combat effectiveness would be nothing more than scratches for Seimei.

As Seimei thought about his gains in the last seven months, he couldn't help but sigh a little

He muttered, "The last seven months were rather peaceful, allowing me to focus fully on my training and complete all the major physique enhancements."

"Thankfully, I didn't encounter any overly powerful enemies or abnormal life-threatening events like the Kitakari town beast riot."

"I almost thought that I had become the main character of some novel, who constantly attracted deadly events."

"But it seems like it was just my wild thoughts wandering around."

"Let life continue this way."

"Amitabha!"

Ding~ Ding~

Seimei's self-talk was suddenly interrupted by the ring from the clock in his room. He turned his head, only to see it was already 9 PM.

"It's already nine, huh?"

"I'd better hurry up then."

"I need to see what my father is researching right now, and I also have to check my recent potion ideas."

With that, Seimei took a few sealing scrolls, opened the door to get out of his room, went outside, and then closed the door behind him.

Then, he quickly left the Senju clan territory.

His destination: One of the hidden research labs of his father, Senju Tobirama.
