Warlock Invasion of Naruto.

"You mean..." Kakashi's expression changed in surprise. He had already realized what was happening, but he still found it hard to believe.

“That’s right, you have awakened the Mangekyou Sharingan, but because you don’t have the physique and bloodline of the Uchiha clan, you can’t unleash the full power of the Sharingan. So after your Sharingan awakened into the Mangekyou Sharingan, it degenerated back into the three-tomoe Sharingan.” Bai Yu explained, “The best solution is to transplant Uchiha bloodline into you, so you should be able to control the Sharingan better.”

"This..." Kakashi fell silent.

“Even if you have transplanted Uchiha blood, you are still Kakashi Hatake, the son of Konoha's White Fang. You haven’t changed in essence.” Bai Yu said, “You haven’t been to the Uzumaki clan for a long time. Rin’s control over the Three-Tails’ chakra has entered a new stage. If you continue to stagnate, it may not be long before Rin’s strength surpasses yours. What will you use to protect her then?”

Kakashi originally came to ask Bai Yu to teach him how to become stronger, but Kakashi hesitated about the method Bai Yu proposed. Bai Yu naturally wouldn't allow this to happen. To become stronger, one always has to make some sacrifices, let alone just changing one's bloodline.

"Thank you, Senior Shiraha." Kakashi made his choice: "I..."

"No need for thanks." Bai Yu waved his hand. "I've said it before, I only helped you to see how far you could go. Just consider it a spur-of-the-moment thing."

It seems that Bai Yu is helping Kakashi without expecting anything in return, but in fact he has already received a reward in the process, which is Kakashi's emotional power.

Kakashi's eyes shifted, realizing that no matter how many words of thanks he uttered, they would be pale and powerless; yet, his gratitude only grew stronger.

As the saying goes, "When people leave, tea cools." Those villagers who once took pride in his father, Sakumo, now only lament his fragile mental fortitude when they mention Sakumo. While praising Kakashi, they also offer seemingly kind reminders not to follow in Sakumo's footsteps, which are disgusting.

"Go back first, and find an opportunity to visit the Uzumaki clan. I'll make preparations in advance." Bai Yu gestured to Kakashi that he could leave.

Kakashi didn't say much, but stood up, bowed deeply to Shiraha, and then turned and left.

Bai Yu watched Kakashi's departing figure with a faint smile on his face, having collected a good amount of emotional power.

"Perhaps after improving his physique, Kakashi will also have the opportunity to learn Sage Mode, and he might even be able to obtain the cells of the giant toad through him."

Bai Yu thought to himself.

Transplanting Uchiha bloodline into Kakashi is a highly probable event.

According to the abilities of the Oni-Garuru Technique, the success rate of transplanting a single bloodline increases if the recipient is already powerful. In particular, Kakashi's Sharingan has been with him for over five years, so he should be more adapted to the Uchiha bloodline.

Afterwards, Kakashi's chakra can be further enhanced to meet the basic chakra requirements for training in Sage Mode.

Kakashi is Minato Namikaze's student. Although he is not as close as a disciple, he is still considered half a grand-disciple of Jiraiya. If he were to ask to learn Sage Mode, Jiraiya would probably not refuse.

Slugs and toads are both relatively docile. Back then, thanks to Tsunade's connections, they received a lot of care from slug clones when practicing Sage Mode, making it much easier than practicing Sage Mode in Ryuchi Cave.

Therefore, with Jiraiya's connection to Mount Myōboku, Kakashi's success rate in training Sage Mode will definitely increase significantly. During his training at Mount Myōboku, it will also be easier for him to come into contact with the Great Toad Sage, and it certainly won't be difficult for him to collect some cells along the way.

"This trip to Konoha has been worthwhile." Bai Yu's lips unconsciously curled up.

......

The fifth day of the second Chunin Selection Exams has finally arrived.

At the central tower of the Forest of Death, in Konoha's 44th Training Ground.

All the candidates who passed the exam gathered here.

166 genin participated, forming a total of 56 teams. This exam eliminated more than half of the teams, with only 76 people passing. Among them, Meteorite was in a team by himself, Itachi was in a team by himself, Kimimaro and Haku were in a team of two, and the rest were standard three-person teams that passed the exam.

Bai Yu and the others arrived at the central tower.

Just as all the examinees were exclaiming that they had finally passed the second exam, the examiners from Konoha called out all the examinees who had passed the exam and were resting in the room in the central tower.

Ninety-two people stood in neat rows in the middle of the tower’s main hall.

However, these people clearly exhibited two different states: one group looked relaxed, as if passing the exam hadn't been too difficult, while the other group appeared disheveled, listless, and many even had injuries.

Especially for those who passed the exam in the last two days, there was hardly any time to rest.

In the queue, Kimimaro, Haku, Meteorite, Hyuga Takashi, Aburame Ryoma, Inuzuka Hana, Uchiha Itachi, and other examinees stood at the front. The entire queue was basically arranged according to the time they passed the exam.

Most test takers will consciously stay away from those who appear unharmed and relaxed.

"Oh?" Bai Yu stood on the second-floor corridor and was taken aback when he saw that the examiner for the second exam was actually Oshima Shuichi.

It seems that because Oshima Shuichi has been frequently carrying out missions to the Uzumaki clan in recent years, he has been kicked out of the political center. Otherwise, an elite Jonin would not have become an examiner for the Chunin Selection Exams.

However, it's also possible that Konoha simply has no one else left, so they're using him to fill a quota.

When Shuichi Tatsuoshima arrived in front of the examinees and cleared his throat, everyone immediately fell silent.

Since most of the candidates who passed the exam were Konoha ninjas, they were quite familiar with this elite Jonin.

"Everyone, first of all, I want to congratulate you on passing the second exam. However, there is a new rule that I need to inform you of. Given that there are too many candidates who passed the second exam, a preliminary selection will be held before the third exam begins," said Oshima Shuichi in a deep voice.

"Preliminary round?"

"New regulations?"

How could this happen?

"That's unfair! How can rules be added on the spot!"

Upon hearing Oshima Shuichi's explanation, some of the test takers immediately started making a fuss. After all, there was no such thing as adding rules at the last minute. Many of them had risked their lives to pass the second exam, and some of their teammates had even died during the exam.

Although they were mentally prepared to die as ninjas, the addition of a preliminary round just before the third exam would eliminate many of them, which was unfair!

Entering the third exam means being able to appear in front of everyone, attracting the attention of villagers, village leaders, and high-ranking officials of the Land of Fire. This greatly helps to enhance the prestige of one's family and oneself.

Which boy doesn't want to become famous at a young age like Kakashi?

Unfortunately, it's no longer wartime, so we can't use battle merits to get promoted. The record of becoming a Jonin at the age of 12 is probably hard for anyone to break.

Looking at the noisy test takers, Oshima Shuichi's expression darkened slightly.

Noticing the examiner's anger, the noise from the crowd quickly subsided, but their dissatisfaction was still written on their faces.

Unfortunately, from Bai Yu's perspective, the combined emotional power of dozens of ninjas was very weak. It was clear that the emotional power of ordinary people required the accumulation of thousands of people to be noticeable.

Hideichi Oshima explained, "Because the audience watching the Chunin Selection Exams this time includes not only villagers and ninjas from Konoha Village, but also ninjas and dignitaries from other countries."

In order to present a high-level competition, it is necessary to start reducing the number of participants now.

If all 76 players make it to the third round of the exam, they would need to play 38 matches in the first round alone, which is unrealistic.

Therefore, this preliminary round will eliminate more than half of the candidates in order to reduce the number of matches in the third exam.

The rules of the qualifiers are simple: no rules, one-on-one combat until one side concedes defeat, loses the ability to fight back, or even dies.

Of course, the proctor will stop the exam when they determine that one of the candidates is unable to resist.

However, this does not mean that the participants are absolutely safe.

After all, among the candidates participating this time, a very small number possess strength comparable to that of a Jonin.

"How could this be?" The examinees' expressions changed drastically. A genin actually possessed strength comparable to a jonin? How could they possibly compete? Not only would they lose if they encountered such a person, but they might even be in mortal danger.

At this moment, Kimimaro, Haku, and Meteorite, who were standing at the front of the candidates, immediately became the focus of everyone's attention, because they were the only three from the outer village who had passed the exam.

In battles between people from Konoha, they certainly won't go all out. If we're talking about those who show no mercy, these three are definitely the ones.

Hyuga Takashi, Inuzuka Hana, and Aburame Ryoma, who were also standing in the first row, couldn't help but glance at each other. Among the candidates taking the exam this time, the three of them were definitely among the top in terms of strength. All three of them had strength close to that of an ordinary Chunin, and together they could easily fight against a special Jonin. However, the upcoming preliminary rounds were one-on-one, and they could only pray that they would not encounter any of Kimimaro, Haku, or Meteorite.

"Anyone who feels unwell, or who feels they may not be able to fight at their best in the upcoming exams, may choose to withdraw from the exams now. Chunin instructors will escort you out at the main gate," Oshima Shuichi continued, looking at the candidates whose expressions were uncertain.

Silence fell over the room once again.

About a minute later, someone finally chose to withdraw from the exam.

"I...I quit."

"Me too."

"And me..."

Many ninjas who looked somewhat disheveled gave up. If they had gone directly to the third exam, they would have had almost a month to prepare. Unless they suffered fatal injuries, they could have recovered. Unfortunately, a preliminary round was added at the last minute. Even if they didn't give up, they would still be eliminated in the battle, so there was no point.

One after another, candidates withdrew.

Soon, only 41 of the 76 candidates who passed the second exam remained.

In a one-on-one situation, one person will receive a bye, and it's unknown who will be the lucky one who gets a bye and goes directly into the third round.

"Alright, if no one withdraws, then the preliminary rounds will begin now." With Oshima Shuichi's command, the electronic screen hanging high above the wall began to scroll rapidly.

—Haku vs. Uchiha Itachi—

Looking at the name displayed on the electronic screen, Bai Yu was slightly taken aback. Was it going to be this exciting right from the start?

"Uchiha Itachi?!"

The Konoha ninjas watching also became interested. They naturally had no interest in the duel between the genin, but Uchiha Itachi was the eldest son of Uchiha Fugaku, a genius boy of the Uchiha clan, whose feat of awakening the double tomoe at the age of 8 had already spread throughout the Land of Fire.

Another boy named Shiro may seem ordinary, but his identity is one that no one can underestimate—he is a disciple of Yagami Shiroha.

This is going to be interesting.

"The other candidates should go to the second floor to watch the match and give the opposing teams some space," Hideichi Oshima reminded them.

Everyone headed towards the stairwell.

"Good luck, Shiro!" Kimimaro whispered as he left.

"Mm." Bai smiled slightly and nodded, then walked towards the center of the hall.

On the other side, a handsome young man wearing a black short-sleeved suit also walked towards the center of the hall.

Haku's expression immediately turned serious. Uchiha Itachi was a formidable enemy.

Especially considering that Itachi forfeited when facing him, Kimimaro, and Meteorite, it shows that he is a very rational person, powerful, calm, and difficult to deal with.

"The first match of the qualifiers begins."

At Oshima Shuichi's command, he flashed to the corner of the wall, his eyes fixed on the two people in the arena. One was the eldest son of the Uchiha clan leader, and the other was Bai Yu's disciple. Neither of them could be harmed, so he would stop the match when one of them was in danger.

Of course, he would do the same if other candidates were in danger. He only said that at the beginning to put psychological pressure on the candidates and test their mental fortitude.

"Please take good care of me." Itachi nodded politely.

Seeing this, Bai smiled and nodded. The two of them walked backward, creating some distance between them, and neither of them made the first move.

Once the two had stopped, Itachi reached into the ninja tool pouches strapped to his legs, holding three shuriken in each hand. All six shuriken shot out at Haku simultaneously.

shhhhhh!

shhhhhh!

Three shurikens flew from the left and right towards the white figure in the center.

Haku's expression turned serious. He then took out six senbon needles and flew towards Itachi's shuriken.

"A thousand sticks? What a strange weapon?"

The ninjas watching the battle were all stunned. Very few ninjas used senbon in battle because the weapon was too weak and difficult to control. Even the Hidden Mist Anbu, who were good at using the Hidden Mist Technique to kill silently, rarely used senbon.
