Jörmungandr's final words dispelled Kōki's concerns.
Indeed, given the current means, there is no faster way to resolve Jörmungandr's weaknesses than this Body Revival Technique; we have no choice but to give it a try.
Kōki took a deep breath and then exhaled heavily.
"Okay, you've convinced me. Let's not delay, let's try it now. With Aizen and me here, we can quickly resolve any problems that arise."
At this point, Kōki had made up his mind that only by discovering problems in practice could they be solved.
On the other side, Jörmungandr breathed a sigh of relief after receiving Kōki's consent. He knew that the original body's personality was rather cautious and only liked to do things that were certain of success. This time, he had no other choice but to agree to his reckless actions.
"Alright, I'll begin then." With that, Jörmungandr opened the scroll in his hand and began learning the Body Revival Technique.
With the clone's exceptional Chakra control, this Body Revival Technique is not difficult for the clone; the only requirement is extraordinary Chakra.
After successfully learning the Body Revival Technique, Jörmungandr nodded to Aizen and Kōki in front of him, indicating that he was about to begin.
After receiving his signal, Kōki and Aizen also began to pay serious attention to him.
Jörmungandr the Chakra within his body to circulate along the pathway of the Body Revival Technique. Gradually, he could feel a slight pain, which then intensified.
"Ah! Ah! Ah!" Jörmungandr Genin out in pain. Fortunately, Kōki had anticipated this situation and had set up a soundproof barrier in the room beforehand.
It must be said that although the pain during the procedure is intense, the results are also very noticeable.
Jörmungandr his body becoming stronger and stronger under the influence of Chakra, but as soon as he started to feel it, he found that he didn't have enough Chakra to strengthen his body.
Left with no other choice, he could only make use of the Chakra he had previously absorbed from Kōki.
With the support of Kōki 'Chakra, his physical secret technique continued to operate, and his body became powerful once again.
"Drink it!"
With a loud shout, Jörmungandr's clothes shattered, and his body transformed into a muscular form, resembling that of a Super Saiyan.
Kōki and Aizen, standing to the side, felt a powerful aura emanating from Jormungandr; the current Jörmungandr indeed resemble Shinnō in some ways.
Yuki Kōki asked, "Can your body support the opening of the Eight Gates?"
The ultimate goal of the Body Revival Technique is to enable the enhanced body to withstand the cost of opening the Eight Gates, thereby gaining immense power.
In the Shinobi World, there are eight gates within a ninja's body that restrict the release of Chakra. Once someone can open Eight Gates, they can instantly gain power dozens of times greater than that of Kage Level.
However, very few people actually manage to open them. One reason is that opening the Eight Gates requires ninjas to have the perseverance to endure pain and risk their lives.
Secondly, to open the Eight Gates, one needs a physique that surpasses that of an ordinary ninja.
In the original story, Rock Lee was able to open the Eight Gates Released Formation during the Chunin Ninja Exams because of his physical training; only those with stronger bodies can withstand the side effects of opening the Eight Gates Released Formation.
Therefore, if the Body Spark Technique only serves to strengthen the body but cannot withstand the cost of opening the Eight Gates, then the expectations for this technique are not that high.
Therefore, only when the Body Revival Technique and the Eight Gates are used in combination can this secret technique be said to be able to change Jörmungandr's physical defects and enhance his strength.
At this moment, Jörmungandr was adapting to his enhanced body. After hearing Kōki's question, he did not reply, but simply nodded.
Then he began to mobilize the Chakra within his body to attempt to Gate of Opening the first gate of the human body. The result was exceptionally smooth. This enhanced body opened the first gate of the Eight Gates in one go, and he did not feel any burden.
With undiminished momentum, Jörmungandr continued his charge towards the Gate of Opening that led to the next one: the Gate of Healing, the Gate of Life, the Gate of Pain, the Gate of Gate of Limit, and the Gate of View. He broke through six gates in a row until he felt he could no longer bear it and then stopped.
Now that he has strengthened his body with the Body Revival Technique, he can open up to the sixth Gate of View in one go, and he can also sense that this is not the limit.
He wasn't confident that he could open the Gate of Wonder after he had adapted to it, but he was also unsure about the final Gate of Death.
Judging from the situation in the original work where Kai opened the Gate of Death, Jörmungandr's current physical body is not yet able to withstand the damage brought by the Gate of Death. Forcibly opening the Gate of Death would only destroy this body of Dark Release.
After successfully opening the Sixth Gate, Jörmungandr his eyes and carefully sensed the changes within his body. The Chakra generated after opening the Sixth Gate was firmly contained within him, unlike others who opened the Eight Gates and released their Chakra aura outwards.
The advantage of doing this is that it allows him to make full use of his Chakra, but it also has certain drawbacks, namely that this Chakra is extremely violent and constantly damages the body's cells.
Fortunately, he possessed superb Medical Ninjutsu, which allowed him to continuously repair his body damaged by the rampaging Chakra.
In this way, his body reached a balance through constant destruction and repair, eventually stabilizing.
Feeling that the Chakra within his body had reached a balance, Jörmungandr opened his eyes. He looked down at his muscular body, and a continuous stream of power surged from the depths of his body. He now felt that he could support the entire world.
Of course, this was just an illusion caused by excessive power, but he knew that his current strength was incomparable to his previous self. To put it bluntly, his previous self could have taken on ten of them.
After seeing Jörmungandr open its eyes, Kōki asked curiously, "Have you succeeded now?"
"That's right, six of the Eight Gates have been successfully opened. Our strength has also increased significantly."
"Won't there be any consequences? After all, the power gained from opening the Eight Gates can't come without a price."
Kōki was a little worried. As someone who had mastered Medical Ninjutsu, he knew very well that opening the Eight Gates would cause damage to the human body, not to mention the Body Revival Technique, which also consumed cellular lifespan. The combination of these two techniques would only make the human body suffer even more.
"There is indeed a price to pay. Using such a combination Taijutsu once will consume half a year of one's lifespan." Jörmungandr had a premonition when he first thought of using this technique; Shinnō's performance in the original work showed that this technique was not without its costs.
However, he didn't care. He had confidence in the entity itself and believed that with further research, a solution would eventually be found.
"Six months of lifespan? It seems there's nothing we can do for now. We can only wait for more research to develop a solution."
In Kōki's view, there is not much difference between consuming lifespan and consuming vitality. Perhaps the problem of lifespan can be solved by increasing vitality, but these are all just his conjectures.
Only after he has studied and researched the subject of vitality in depth can he provide an answer.
"No rush, there's no need to rush into solving this problem yet. Besides, this secret technique is only used in battle, so under normal circumstances, there's no need to worry about its lifespan."
Jörmungandr wasn't in a hurry about his lifespan; his only thought was to find an opponent immediately to let him experience the power of this combination of Taijutsu.
