Starting with Wood Release, he survives in Konoha Hospital and becomes a big shot.

Inside the tent, Yao Xingji's lips slowly curved into a bright smile.

"In just a few minutes of fighting, my chakra increased by almost ten kilocalories, which is roughly the level of ten Chunin. That's countless times faster than Konoha Hospital!"

"And he also acquired a lot of good ninjutsu, but unfortunately, they were all for treating minor injuries, and he didn't acquire any powerful bloodline limits or anything like that."

Yao Xingji meticulously recounted his gains this time, his smile growing brighter and brighter.

People often talk about profiting from war, and Yao Xingji never imagined that one day he would also make a fortune from war, and a very large one at that!

That's right, the healing just now, Yaksha Extreme, wasn't just cast on Kakashi alone, but on most of the injured ninjas on the battlefield.

It included not only the ninjas of Konoha, but also the ninjas of Iwagakure.

Kakashi was naturally the primary target of Yaksha's treatment. Most of the power of the Eye of Salvation was directed at Kakashi, which was necessary to maintain Kakashi's fierce fighting style of exchanging injuries for injuries.

At the same time, Yao Xingji was also healing other ninjas on the battlefield from time to time.

These ninjas only need to expend a small amount of their eye power to heal minor wounds or even scratches, and they can gain considerable benefits. This led Yao Xingji to abandon his insistence on his faction and choose to heal the Iwa ninjas as well.

However, these treatments were for very minor injuries and did not affect the overall battle situation; they were merely a way for Yao Xingji to exploit the enemy.

After all, healing an enemy's arm won't have any impact on our side.

A few minutes later, when Sakumo Hatake appeared at the Yakusei tent carrying Kakashi, he saw Yakusei lying on the bed, half-dead.

"Hoshiki, are you alright?" Sakumo Hatake immediately abandoned Kakashi and ran over to check on Hoshiki's condition.

Kakashi, who was thrown to the ground, was completely bewildered. When he sat up, he saw his father helping Yao Xingji sit up, looking at him with a loving and anxious expression.

"I'm really not his biological son..." Kakashi was almost in tears.

Yao Xingji used the Heart of the Universe to seal off all the chakra in his body, and said weakly to Hatake Sakumo, "It's nothing, I just overused my chakra, I'll be fine after resting for a while."

"Is Kakashi alright?"

Upon hearing Yao Xingji's question, Kakashi immediately got up from the ground. He had recovered some of his strength and was now able to move without any problems.

"I'm fine. Thanks to your treatment today, otherwise I probably wouldn't have been able to leave the battlefield alive, let alone wreak havoc!" Kakashi said immediately.

"You deserve most of the credit for today's work!"

"I'm glad you're alright," Yao Xing said weakly.

His smile was so genuine and pure, he seemed even happier than if he had found a treasure.

Looking at Yao Xingji like this, Kakashi felt ashamed. He hadn't dared to question his father's concern for Yao Xingji.

"Don't treat yourself so recklessly in the future, or your body won't be able to take it," Hatake Sakumo said, patting Yakusei's head.

Looking at Yao Xingji's smile, he could feel that Yao Xingji was genuinely happy and joyful. It was an aura that emanated from within and could not be faked. Was it because he had saved Kakashi's life?

What a simple and honest child.

At this moment, even Sakumo Hatake couldn't help but be impressed by Yakusei's noble sentiments.

Look, this is what dedication and the Will of Fire truly mean. This is the real spirit of dedication and the Will of Fire. To risk one's own safety for the lives of others, and even when one is exhausted while healing a comrade, to still feel genuine joy for others—this is something few can do.

“Okay, I understand, Captain Hatake,” Yao Xingji said.

He tried his best to control his expression and not show any joy, because he had gained so much from this war that he simply couldn't control the joy in his heart.

"Oh no, I acted too happy. I wonder if it will arouse Sakumo Hatake's suspicion. But I've really gained a lot. I feel like the Upside-Down Heaven might have changed too..."

Chapter 165 Sakumo Hatake's Instructions

Soon, Uchiha Shisui and the others arrived at Yakusei's tent.

"I never expected the Eye of Salvation to be so powerful! I want to use it next time too, I want to unleash a devastating attack!!!" Obito Uchiha exclaimed excitedly.

Kakashi's previous rampage had been etched into everyone's memory, leaving an extremely deep impression on them. Even now, all the ninjas in the military camp are talking about Kakashi.

They didn't know the reason for Kakashi's outburst or the essence behind it, but that didn't matter. What mattered was Kakashi's terrifying strength and fearless fighting style, which made everyone's blood boil.

Those who understood the reasons behind it, such as Obito Uchiha, knew that Kakashi's rampage was partly due to his own strength, but more importantly, it was due to the healing from the Eye of Salvation of Yakusei.

Without treatment, Kakashi would be dead by now, let alone be able to dominate the battlefield.

With the help of the Eye of Salvation, Kakashi was instantly transformed and became a hero in the eyes of countless people.

No one wants to be a hero. Now, a shortcut to becoming a hero is right in front of them. As long as they have the help of Yaksha in their next battle, they can achieve the same level as Kakashi and become famous throughout the ninja world in an instant.

Not only Obito Uchiha, but everyone else looked at Yakushiro with a different gaze. This was a rare opportunity, a chance for them to become heroes.

"Nonsense! The Eye of Salvation is for saving lives in critical moments, not for you to show off. This is not an exception, otherwise Xingji's own body will suffer from problems due to overuse of the eye technique, which is something I absolutely do not want to see." Hatake Sakumo's slightly angry voice poured cold water on everyone.

Everyone looked at each other, not expecting Sakumo Hatake's attitude to be so resolute.

Yao Xingji's expression shifted, and a thoughtful look appeared in his eyes as he looked at Hatake Sakumo.

"Alright, you've exhausted your Star Chakra and eye techniques. You may all leave now." Hatake Sakumo directly dismissed them.

"This...we'll be staying here..." Yamato said somewhat awkwardly, as they were sharing a tent with Yao Xingji.

“I’ll arrange separate tents for you. You can rest here with Hoshigi,” said Sakumo Hatake.

"Yes." Yamato dared not say anything more, nodded to Yakusei, and turned to leave with Uchiha Shisui.

"Dad, I..." Kakashi was about to say something when he was interrupted by Sakumo Hatake.

"You can go down now. I'll stay here with Hoshino for a while," Hatake Sakumo said.

Kakashi turned and walked out of the tent, feeling wronged, and lamented in his heart, "I'm definitely not his biological son."

in the tent.

Sakumo Hatake frowned as he looked at Yakusei, as if he was pondering something. He remained silent for a long time, but he did not leave either.

"Starry Sky, be careful when using the Eye of Salvation in the future. Don't overdraw your body and eye technique like you did this time, understand?" Hatake Sakumo said earnestly.

"Why...?" Yao Xingji asked, feigning curiosity.

“You’re still young, there are some things you don’t know.” Hatake Sakumo sighed. “The more powerful the eye technique, the greater the risk. Your Eye of Salvation is very powerful, that’s obvious, but the power of this eye technique may come at the cost of something, such as your eyes, or your body.”

"Some eye techniques, if used too much, will cause blindness; others, if used too much, will cause death..."

"The greater the power, the greater the danger. Remember this!"

Sakumo Hatake spoke slowly and in a low voice, as if he were explaining something to his own child.

Yao Xingji's heart trembled slightly.

Of course he knew what the consequences would be if he used too many of the powerful eye techniques that Sakumo Hatake had mentioned. However, his Eye of Salvation was completely different from the other eye techniques in Naruto; they were not part of the same system at all. Therefore, he did not need to worry about any side effects from using them too much.

"Also, you need to be careful with Shisui and Yamato around you. Their purpose in protecting you may not be pure," Hatake Sakumo continued.

"Mmm." Yao Xing nodded obediently.

This desperate attempt to save Kakashi seems to have made Sakumo Hatake trust Yakusei even more.

"Also, Danzo... never mind, I'll deal with Danzo myself. You don't need to go with him to clear out the Iwa ninja. I..." As Hatake Sakumo said this, Yakusei immediately objected.

He's going to take advantage of people, how can we just let it go like this?

"Captain Hatake, I think I still need to go. Lord Danzo is hostile towards me because he doesn't understand me. Once he understands me, he won't treat me like that anymore."

“If I keep avoiding him, he will still be hostile towards me in the future. As the assistant to the Hokage and the leader of Root, I feel that I need to get along with him. After all, I will still live in Konoha in the future, and it is not good to always be hostile to him.”

"Moreover, Konoha needs me now, so I can't back down. I want him to see my Will of Fire!"

Yao Xingji clenched his fist and swung it forcefully.

Sakumo Hatake: "..."

At this moment, Sakumo Hatake felt his mind was a bit of a mess. What was he just about to say? Why couldn't he remember it?

“Well… what you said makes some sense. Since you want to prove yourself, I won’t stop you. I will go to Danzo to explain your situation and at least ensure your safety,” Hatake Sakumo said finally.

"Okay, sure." Yao Xingji nodded obediently again.

If Danzo really wanted to cause him trouble, Yao Xingji would dare to kill him off early.

They didn't even give Danzo a chance to seal a bridge; they just sealed away the air.

"You should get some rest. I have other things to take care of," Sakumo Hatake said, getting up.

As the commander guarding this region, Hatake Sakumo certainly has a lot on his plate, so it's quite remarkable that he was able to spare so much time to talk to Yakusei Kiku.

After Hatake Sakumo left, Yao Xingji activated his Eye of Salvation, surveyed the surroundings, and, after confirming that there was nothing unusual, immediately calmed his mind and entered the Heart of the Universe.

The sky hangs upside down.

Yao Xingji's figure appeared, and the entire hall seemed to become even more magnificent, especially the Heart of the Universe in the statue's hand, which was now imbued with even more azure creative power and scarlet destructive power.

Meanwhile, Yao Xingji's current 40 chakra units are enough to support him in making some new attempts.

"I wonder if there have been any changes in this upgrade..."

As soon as Yao Xingji finished speaking, he flew up and arrived in front of the Heart of the Universe, hovering in mid-air.

Chapter 166 The Mask of Pain

Yao Xingji stretched out his right hand, pointed out with one finger, and his index finger landed on the Heart of the Universe.

hum!

A ring of red and blue light spread out, instantly making the surroundings illusory, as if one had entered a dream world.

"This is……"

Yao Xing looked around in confusion. The entire Upside-Down Heaven Palace became hazy, shrouded in a layer of colorful mist.

Swish!

A beam of light swirled out from the heart of the universe, condensing in front of Yao Xingji, radiating a seven-colored light.

Before Yao Xingji could even see what was in the light, dozens of beams of light flew out from the Heart of the Universe and hovered around him.

Yao Xingji's gaze fell on the ball of light closest to him, and he could clearly see that a strangely styled mask was wrapped in the seven-colored light.

"This is... the Pain Mask?"
