A single-player post-apocalyptic game, but with an all-female teammate mod.

After chugging down more than half the bottle in one gulp, she said again, "So? What do you want to do with me now?"

Looking at the blonde, busty female ninja with a slightly flushed face and occasional hiccups, Aono shook his head and chuckled, "What do you mean by punishment? I said from the beginning that we are partners and teammates."

"Putting aside the fact that our current opponents are all mechanical monsters, it doesn't matter if you have hemophobia."

He paused, then smirked and said, "My purpose in recruiting you is not to have you fight, but to master chakra."

Before witnessing Tsunade's talent, Aono had doubts about whether he could master chakra, after all, the world had changed.

But after seeing the effects of Tsunade's Chakra talent, he was completely relieved.

While chugging her drink, Tsunade asked curiously, "What's a mechanical monster?"

"That's not important. Even if you can fight now, you still won't be able to fight monsters with blood in the future."

Aono waved his hand, smiled, and looked Tsunade up and down, saying, "Since you don't want to fight, then you can earn your reward through other labor."

"What do you want to do..."

Looking into Aono's burning gaze, memories of the past two days surfaced in Tsunade's mind.

She instinctively crossed her arms over her chest, saying, "Let me make this clear first, I will absolutely not sell my body."

"I don't lack women."

Aono rolled his eyes speechlessly and explained, "What I mean is that I want you to help us master chakra and teach us the techniques and various ninjutsu we use."

"The reward is 50 gold coins per day, which is enough for you to drink and eat."

"Of course, if you overcome hemophobia and are willing to join the fight, I would also be very happy to welcome you."

Tsunade slowly lowered her hands that were protecting her, thought for a moment, and then simply nodded in agreement.

Seeing that she agreed, Aono eagerly pulled her towards the training room.

"Hey, the wine, my wine, I haven't finished it yet!"

"Don't worry, no one will take it from you. You can drink it slowly when you get back."

And so, under Tsunade's reluctant gaze, the group of four left the captain's cabin and went to the training room.

Upon entering the training room, a system notification immediately popped up.

Just like Aono thought, Tsunade, like the Kage, could also join the ranks.

Currently, there is only one position available in the Level 1 training room, and Tsunade is the one who joined this time.

After Tsunade joined the team, the training room also received two bonus effects.

These are chakra extraction efficiency +20% and ninjutsu mastery efficiency +20%.

The bonuses provided by joining Heying are the same, only the categories are different.

It seems that in terms of being a teacher, Tsunade and the Kage are at the same level, and the amount of gold coins required is also the same.

100 gold coins per hour.

Aono immediately spent 100 gold coins to start training.

"Alright, let's begin."

Having made all the necessary preparations, Aono sat cross-legged in the center of the dojo and looked at Tsunade.

Tsunade stretched her body, and her expression finally became more serious.

"Chakra is essentially a combination of physical and mental energy."

As she spoke, she pointed to her abdomen.

"Physical energy comes from all the cells in the body, while mental energy comes from the brain and will. Only when the two are balanced and integrated can chakra be generated."

Aono sat cross-legged, closed his eyes and focused his mind, following her instructions to sense the two unseen forces within his body.

No matter how hard he tried to concentrate, his physical energy and mental energy were like two rivers that never intersected.

No matter how he tried to guide them, they remained completely still.

Tsunade stared at Aono for a long time, and suddenly, as if struck by a flash of inspiration, she realized the problem.

She clicked her tongue, walked behind him, squatted down, and gently placed her right hand on his back.

A wisp of warm chakra flowed from her palm into Aono's body.

In that instant, Aono felt as if some invisible membrane had been pierced, and the previously dormant energy suddenly became active.

Physical energy surges like a tide, while mental energy flows through it like the wind.

Guided by his will, the two energies began to slowly approach, intertwine, and merge.

This is Tsunade's unique talent effect.

Without her guidance, even knowing how to extract chakra wouldn't be enough to succeed.

The extraction of chakra is not something that can be done overnight.

If the ratio of physical energy to mental energy is slightly off, chakra cannot truly take shape, let alone be stored in the body.

Once, twice, three times...

Under Tsunade's guidance, Aono continuously adjusted the ratio of the two.

Fail, try again, fail again, try again.

The training room boosted the efficiency of each attempt by 20%, while his vast reserves of physical and mental energy gave him ample room for trial and error.

Time passes little by little.

Just as he was adjusting the proportions again, Aono suddenly felt an unprecedented sense of smoothness within his body.

The two energies finally merged stably, transforming into a brand new force that quietly circulated through the meridians.

He opened his eyes, a glint of light flashing in them.

"It's done."

There were still a few minutes left before the training session ended.

In other words, Aono successfully extracted chakra in just one hour on his first attempt.

46. ​​Tsunade joins the team

This speed would be considered genius among geniuses even in the Naruto world.

But Aono was not arrogant.

With sufficient mental and physical energy for trial and error, plus the boost from the training room, this speed can only be described as normal.

The process of the little cook extracting chakra next proved this point.

Dudu took a little longer than Qingye, but it was only about an hour and a half.

However, when it was finally Ying's turn, a slight accident occurred.

She was unable to extract chakra.

Even with Tsunade's talent as a guide, it wouldn't work.

In Tsunade's words, the Kage's body is filled with natural energy, leaving no room for chakra to survive.

Aono was not surprised by this.

His decision to have the Shadow attempt to extract chakra was a test in itself, and it's normal for two different supernatural systems to clash.

The natural energy that Tsunade mentioned is actually the omnipresent elemental power that the Kage spoke of.

In Naruto, ninjas cannot directly use natural energy; they must neutralize it with chakra.

It is extremely difficult.

One mistake could be fatal.

If successful, you will master Sage Mode, greatly increasing your combat power.

But Shadow is a demon god of the Teyvat continent, and the use of elemental power is entirely instinctive, with his body constantly filled with lightning element.

The inability to use chakra is completely irrelevant to a Kage, whose own extraordinary power is in no way inferior to the chakra system.

The chakra system can be so powerful that it can roam the entire universe, even among the top powerhouses on the continent of Teyvat.

Ultimately, the upper limit of a superhuman system depends on the person using it.

What suits you is the best.

After all that fuss, it was almost dawn, so Aono decided to take a day off.

He said he was going to rest, but he didn't go to sleep.

Not only did he not sleep, but Ying and Dudu did not sleep either.

The first light of dawn failed to penetrate the heavy doors of the training room.

Aono and Dudu sat cross-legged indoors, immersed in extracting chakra.

Successfully extracting chakra is only the beginning of the first step.

Only when the physical and mental energies are fully integrated and the chakra reserves reach their maximum can the first step be considered truly complete.

According to Tsunade, after Aono extracted all his chakra, he should have had the chakra level of a Jonin.

Dudu is a bit worse, probably at the level of a very high-ranking ninja.

This refers to quantity, not to having that kind of strength.

Aside from tailed beasts and innate talent, the only way to increase chakra is through training to improve physical and mental energy.

However, Qingye and Dudu don't need to go through all that trouble; they just need to fight monsters and level up.

The upgrade brings comprehensive benefits, including both physical and mental well-being.

With the added trust from Dudu and Ying, Qingye's physical and mental energy can be further enhanced.

At the same level, his chakra reserves are in no way inferior to Tsunade's, who possesses the Sage Body.

If there's a trust value bonus, it could even surpass them.

While Qingye and Dudu were engrossed in their cultivation, Ying did not stop either.

On the other side of the training room dojo, tiny flashes of lightning flickered continuously.

Unlike Aono and the other two, she did not sit still, but instead wielded the heavy naginata with impenetrable skill.

With a single slash, the sharp blade intent, accompanied by thunder, cleaved the air with a piercing explosion.

For her, this extreme use of power is not asceticism, but a form of relaxation and enjoyment.

Every stretch of her muscles, every resonance with the power of the elements, brought her a genuine sense of exhilaration.

Aono knew that Kage was a martial arts fanatic, but this was the first time he had felt it so directly.

Fighting every day isn't enough; even when they're resting, they still have to practice martial arts!

Thus, the three of them spent the day in their respective ways of "resting" and welcomed another night.

The atmosphere was unusually relaxed during dinner.

During the meal, Tsunade, her face flushed and with a slightly tipsy, languid air, said she wanted to go out and see the world the next day.

Aono smiled and agreed.

Tsunade didn't want to fight, but that didn't stop her from wanting to go out and see the world.

She'd been cooped up in the Ark for ages with no entertainment, and today had gotten her incredibly bored.

While Aono and the others were "resting" during the day, Tsunade, having completed her teaching duties, went to familiarize herself with the surroundings.

The canteen, warehouse, manufacturing workshop, shop, and dormitory.

She spent her newly acquired gold coins on lunch at the cafeteria, and then went to the store to buy some things she needed and liked.

Clothing, blankets, alcohol, playing cards, dice, etc.

After shopping, she went to the dormitory and occupied an empty room.

She didn't choose to live with Dudu and Ying, but instead went to an empty dormitory.

During this time, she saw five survivors in NPC form, which made her believe the memories in her mind even more.

At this moment, Tsunade leaned back in her chair, twirling a wine glass between her fingers, her gaze drifting somewhat as she looked at Aono.
