In Konoha Village, it is very rare for Genin to receive high-level missions beyond their level, especially this kind of situation of protecting a daimyo of a country is quite rare.

At noon the next day, Mizuki arrived at the meeting place on time and found that three students were already waiting.

"You're so slow, Teacher Mizuki!" Inuzuka Kiba complained, getting a little impatient.

"You are too impatient, Kiba. Being a ninja is a profession that requires punctuality. Being on time is the key. It's not that I'm too late, but that you guys are too early."

Mizuki's words immediately shut up Inuzuka Kiba's complaints. Compared to the battle-hardened Mizuki, a little kid who talked to a pet dog all day was obviously no match.

Patting Akamaru who was squatting on Inuzuka Kiba's shoulder, Mizuki said with a smile: "As your teacher, I am very happy to see that you have not gained weight. It seems that you have not forgotten your duty as a ninja during the vacation, and have not been too lazy or neglected your training..."

"Teacher Mizuki, why do I feel like you've gained some weight?" Aburame Shino suddenly interrupted.

"Eh? How is that possible?" Shuimu replied with a dry laugh, "You're wearing too many clothes. Hahaha!"

How can these little guys understand that it is normal for adults to accidentally eat a little more during social events during the holidays? Can they also speak the truth carelessly?

Mizuki glanced at Aburame Shino, who looked serious but had some evil thoughts in mind.

"Next, get ready to go!"

"Huh, you don't even explain the mission?"

"We'll talk as we go."

…

In the underground laboratory, Shuimu's clone was concentrating on watching the experiment in front of him.

The two assistant clones tried their best to suppress the curse marks that erupted on the experimental subject, and the red and black runes slowly spread. After a while, without much movement, they covered the whole body and touched the smooth forehead, where the curse mark was exactly the same as the caged bird of the Hyuga family.

The moment the two curse seals collided, the bird in the cage began to spread rapidly. Black runes spread, protecting its forehead and pale cheeks. It seemed that the entire head was covered.

At this moment, the experimental subject, who had remained motionless even when the curse seal exploded, began to shake rhythmically.

"It was an instinctive reaction. I think it was because I felt pain."

The clone in charge of the experiment nodded and instructed: "Relax the restrictions on the curse slowly and pay attention to protection. If something goes wrong, use the Flying Thunder God Technique to move the entire scene away immediately."

This dangerous experiment was carried out after careful calculation and preparation for nearly three months.

From getting the curse seal, to Jūgo's cell sample, to the bird in the cage, the difficulties encountered in between were much more than expected. I don't know how much time was spent on an immature control plan.

Following the clone's instructions, the curse seal began to become active again, and the red and black runes that were originally suppressed below the neck began to slowly invade the territory of the caged bird curse seal, starting from the chin, to the mouth, nose bridge, and finally spreading over the eyes, and touching the body of the caged bird again.

The moment the two curses intersected again, the subject's head shook violently, and then his eyelids trembled, and then slowly lifted up, revealing a pair of dark and deep eyes.

"Control yourself and don't be affected by other things."

As soon as he finished speaking, the caged bird, which was originally at a disadvantage, began to emit a silver light, and the violently colliding chakra began to gather towards the eyes. Finally, a surprising miracle happened.

"It's the Sharingan!" Although I had guessed this and had expected the experimental results, I didn't expect it to be true.

"Each of your eyes is a magatama. Do you want to continue?"

"No need, start to slowly stop now." The clone rejected the proposal, "We have already achieved the desired result."

As the force suppressing the curse increased, the red and black runes gradually faded and were sealed and hidden under the skin of the right arm.

The chakra fluctuations of the experimental subject slowly calmed down, and the two Sharingans returned to their pitch-black pupils.

Everything went smoothly, and Shuimu's clone was relieved. If he continued, he would either lose control or the experimental subject would completely collapse. There was really no need to take that risk.

"I originally thought that the Byakugan of the Hyuga family was the most precious treasure, but I didn't expect that this caged bird is no less valuable. Chakra lock, spirit lock, heart lock, it really lives up to its reputation!"

The bird in the cage is the root cause of the tragedy of the Hyuga clan. It is not an exaggeration to say that it is fate. It is physically attached to the brain and mentally rooted in the soul and chakra. It also restricts the ability of the Byakugan, allowing the main family to fully control the branch family. Putting aside the conspiracies and shady dealings, the curse of the bird in the cage is really too overbearing.

However, even fate is not necessarily a reliable thing in the ninja world.

The number of the Great Derivations is fifty, and forty-nine of them are used. The accident is the one that escaped. Although there is no such complicated saying in the ninja world, the words that Hatake Kakashi often says, "Ninjas cannot be measured by common sense", actually have similar meanings. Even the ancestors of the Hyuga family who created the caged bird must have understood this truth. Leave a way out for others, it may come in handy at some point.

A bird in a cage means a bound fate, and only death can free it from the cage. But what would happen if there really was a ninja who could free the bird from the cage alive? Unfortunately, the only ninja who had this ability in the original work, Hyuga Neji, died in the Fourth Ninja World War.

"A bird in a cage is ridiculous. It was made clear at the beginning."

The bird in a cage does refer to a trapped person, but the original meaning is not that simple. The child in the womb is the original meaning of this word, which not only symbolizes the hardship of birth, but also carries the blessing of the birth of life.

"The conclusion is obvious." A Shuimu clone dressed in a white coat began to summarize the experiment, "The bird in the cage cannot be driven out by external forces, otherwise it will trigger a dual counterattack of the body and mind. But it is feasible to break through with one's own strength."

“Every time you break through a limitation, it’s like throwing away a burden, and there will be a qualitative improvement.”

“Misfortunes are often the root of blessings, and blessings are often the root of misfortunes.”

"It's just that I haven't tested the limits of the caged bird yet..."

The leader's clone waved his hand, "If we continue, we will inevitably touch the bottom line of morality. Also, this experimental subject doesn't have much life left. In the remaining days, let him see the sunshine outside. Spring is here, a season of vitality!"

"Should we ask the main body for its opinion?"

"No need, we are one and the same, so the way we handle things must be the same."

Even though the way of birth is different, the person lying on the test table is a newly born human being, and no longer an experimental subject without soul and self.
