Konoha was also attacking the surrounding small villages, which led the Fire Country to constantly expand and gain more resources.
Even the other Great Ninja Villages were doing the same, ravaging all the small villages in their vicinity.
But small villages and resources are limited.
With three large countries, it was inevitable that there would be friction between the Big Ninja Villages.
Although it seems like it will take time to brew, every person with any insight knew that this war was inevitable.
Compared to things like the Second Ninja World War, Naito's life and death battle seemed a bit insignificant.
"Ninja World War II, huh...," With a sigh, suppressing his thoughts, Naito continued his training.
A few days later, Naito finally estimated that his body was strong enough to be able to open the Second Gate, the Shock Gate, of the Reverse Hachimon Tonko.
The first gate of the Reverse Hachimon Tonko was the final gate, the Heart Gate.
The Second Gate, of course, will also be reversed, which is the Seventh Gate, the Gate of Shock.
This gate was extremely important, not less important than the First Gate, the Heart Gate.
Because from the Heart Gate to the Concussion Gate located in the stomach, a link will be formed between the two gates!
The Concussion Gate was the link between the heart and the other gates, the next five gates were in a straight line, it was a completely direct path to the brain.
After stretching his body, Naito sat cross-legged and began to attack the Second Gate, the Concussion Gate.
Naito's two months of training was comparable to other people's training for half a year or even longer.
The power he gained after opening the First Gate was more than he expected.
No one could predict how much stronger he would become after opening the Second Gate.
To open the Second Gate successfully, he would have to open it on the first try!
Like the first gate, he impacted it first with shock power, then sent a wave of chakra directly into the gate to form the second impact.
The shackles of the gate were completely destroyed!
With the opening of the Second Gate, the Shock Gate, the flame hidden in Naito's heart spread directly through his tenketsu and reached the Shock Gate.
Then, the second gate also seemed to burst into flames!
What felt like a flame was actually Chakra!
At this moment, Naito's Heart Gate was completely connected to the Second Gate below the lower abdomen due to a fragile connection.
This was the natural connection of the Reverse Hachimon Tonko.
The Second Gate began to generate chakra, the amount was even greater than the amount generated by the First Gate, causing an imbalance in the Second Gate.
However, because of the existence of the connection between the two gates, the imbalance quickly disappeared.
At this point, with the chakra provided by the two gates, Naito's chakra volume crossed the threshold of a Chuunin in an instant.
Even compared to some Elite Chuunin, he wasn't much worse!
This was a great improvement.
Moreover, with the new connection between the gates, the chakra formed a cycle between the two gates.
Originally, the heart gate chakra only improved the heart, but due to the opening of the second gate, a connection was formed in which the chakra is transferred between the two gates.
During the transfer process, it was naturally inevitable that some of the chakra would disperse into his muscles and bones, passively strengthening his muscles and bones.
A change that passively improves the body!
"The amount of chakra is almost comparable to that of an Elite Chuunin? Then it looks like I can try to develop some Jutsus," After feeling the chakra in his body, a smile appeared on Naito's face.
Although he expected it, he couldn't hide the joy on his face when he felt such a rapid increase in his Chakra volume.
For Naito, there was no point in learning ordinary Jutsu, such as Great Fireball and Wind Jutsu: Great Rupture.
In fact, for someone like Naito, who possesses the Kekkei Genkai Trembling and possesses a strong body and great speed, it does not make much sense to learn Jutsus that require hand seals.
Therefore, Naito wanted to develop Jutsus that are suitable for his circumstances, and even Jutsus that combine with his Kekkei Genkai.
"My body began to change," In addition to the increase in chakra, Naito began to feel that his body began to adapt rapidly.
Because Reverse Hachimon Tonko permanently opens the doors inside the body, its effect is different from ordinary Hachimon Tonko, which provides explosive power.
Rather, it was gradual and progressive.
However, as long as the gate opening is successful, this process will not take long.
After Naito opened the Heart Gate, it took two days for his body to become fully accustomed, and the second gate, the Shock Gate, will not take long.
Indeed, after almost three days, Naito's body completely adapted to the opening of the second gate.
After adapting, Naito's speed could almost compare with that of an ordinary Jounin, and Chuunin level ninja, unless they specialize in speed, will not be able to compare with Naito.
In addition, the shockwaves became more powerful due to the opening of the Second Gate.
The power was almost three times stronger than before!
It completely crossed the gap between the power of a C-Rank Jutsu and a B-Rank Jutsu.
Now, with Naito's power, he can destroy a B-Rank Jutsu with a single blow!
In addition, as his body grew stronger, the attack range would also increase.
Originally, Naito's attack range could only reach two meters at most.
That range belongs to melee attacks.
And now, under Naito's full force strike, the range of the shockwave has reached five to ten meters!
Within five meters, the shockwave does not weaken and can destroy B-Rank Jutsu. Within a range of five to ten meters, it can still destroy C-Rank Jutsu!
The attack range changed from a melee attack to a long-range attack, which largely eliminates Naito's weakness to long-range attacks.
C-Rank Jutsus are the most commonly used by Chuunin.
B-Rank Jutsus are commonly used by Jounins.
A-Rank Jutsu are used by Elite Jounins, but in general, many Elite Jounins do not even learn A-Rank Jutsu.
After all, as long as the user masters a chakra nature and integrates it into a B-Rank Jutsu, his power was already very strong.
Most ninja do not choose to waste their time with A-Rank Jutsus, but instead choose to train Chakra nature and enhance the power of B-Rank Jutsus.
In other words... Whatever you throw in his face, Naito will simply destroy it!
However, there was still one more problem, he didn't forget it, but he was sure it wouldn't cross his path until now, so he ignored it.
"Besides Taijutsu and Ninjutsu, there is also Genjutsu in this world!"
After calming his excitement, Naito lowered his head and began to reflect, "I ignored this fact because I was sure that no one would use it against me until now. Why learning Genjutsu is much more difficult than learning Jutsus, but among the ninja of the Uchiha Clan, Genjutsu is just a common attack method."
