After the training of the Strange Force Flow and the Fierce Konoha Vajra Force Whirlwind was a little successful, Ding Kai also shifted the focus of his cultivation to ninjutsu.

This time, Ding Kai practiced fire escape.

The development of water escape is somewhat difficult, and limited by the environment, the applicability is not as convenient as fire escape.

Ding Kai opened the scroll in his hand and browsed it carefully. This is the ninjutsu scroll of the Fire Escape Sho no Yaki Technique, which records the sealing method of this B-rank Fire Escape.

Learning how to seal it is only the first step.

The second step is to improve it.

The devouring chakra in Ding Kai's body is small in quantity but high in quality. If the general ninjutsu is not improved, it is equal to waste.

Ding Kai browsed the Fire Escape Ninjutsu recorded by the Roots, Shadows, and Uchiha clans. After the final comparison, it was found that among the B-level fire escape ninjutsu, this one was the most suitable for him.

Fire Escape: Suyaki - In the original book, when Payne attacked Konoha, a member of the Shadows used the ninjutsu of the multiplier dog summoned by the Animal Path. Unlike the normal Fire Escape Technique, this technique does not emanate from the mouth, but burns directly on the target.

The reason why this B-level fire escape is most suitable for Ding Kai is that the flame of this fire escape burns directly on the target.

Ding Kai's Devouring Chakra, the biggest feature is the Devouring attribute. However, due to the limitations of ninjutsu, devouring chakra is rarely able to scorch enemies for too long. Therefore, the devouring attribute cannot be used perfectly.

The Primal Burn technique burns directly on the target, which greatly increases the scorching time. What's more, it can perfectly play the devouring attribute.

However, this ninjutsu is not like Amaterasu, glaring at it with a chakra, and the fire of Amaterasu begins to bubble. In fact, this ninjutsu also has a lot of flaws.

First, the target character can't move!

Second, although it is not a fire escape from the mouth, it also needs to spit out the chakra from the mouth. It is easy for enemies to detect and dodge.

That's why this ninjutsu is powerful and dangerous, but it doesn't make much sense in actual combat. In the original book, the dark ninja can only deal with psychic beasts that are imprisoned by the thunder pillar and covered by the earth.

In the B-level Fire Escape Ninjutsu, it is far less practical than the Mighty Dragon Fire Technique and the Fire Dragon Flame Bomb.

However, after browsing so many books on Fire Escape, coupled with his own experiments, Ding Kai also found his own special solution.

First, there is the issue of the chakra time limit.

The so-called statute of limitations mostly refers to the limitation of the time limit of the chakra attached to the body or the weapon of time from the body.

Generally speaking, when using special ninjutsu, a large number of chakras are attached to the body surface (such as the oil girl Shiwei's insect trick technique), but in fact, the chakra is not just the original chakra outside the body surface, and the new chakra constantly replaces the original vanished chakra.

If Naruto uses an ordinary spiral pill, it needs to consume one percent of his own chakra, there are about 2 trillion cells in the human body, and if Naruto doesn't care about it after renewing the spiral pill, the spiral pill will disappear after a minute, just like Naruto's shadow clone.

The chakra that is put out, if it is not left alone, only has a one-minute statute of limitations.

Second, how to attach the devouring chakra released to the enemy?!

The enemy does not stand still, and in the course of the battle, the positions of both the enemy and the enemy are constantly changing.

Ding Kai's devouring chakra is difficult to firmly attach to the enemy.

Moreover, Ding Kai's Devouring Chakra is not colorless, but a special black color. Attached to the outside of the enemy is easy to detect.

For both of these questions. Ding Kai also found a solution!

It's a soft fist modeled after the Hyuga clan!

Jutsu is a family tradition of the Hyuga clan. Soft fist is a physical technique that punches one's own chakra into the enemy's body, thereby damaging the chakra's pathway "meridian system" and internal organs in the enemy's body.

Similarly, Ding Kai punches his devouring chakra into the enemy.

Although Ding Kai didn't have white eyes, he couldn't accurately damage the enemy's meridians and acupoints. However, Ding Kai's Devouring Chakra's Devouring attribute can slowly devour the enemy's Chakra, thereby slowing down the dissipation of Devouring Chakra.

The duration of Ding Kai's devouring chakra outside the body has increased from one minute to ten minutes, a full tenfold!

Moreover, the devouring attribute of devouring Chakra is far less domineering than the devouring power in Ding Kai's body, and the enemy can't detect it at all.

In this way, Ding Kai also got a new Fire Escape Ninjutsu, called Fire Escape Dark Essence Burning Technique!

This ninjutsu first requires that when fighting the enemy in close quarters, perform the Devouring Flow Gluttonous Body Technique. At this time, it is no longer to devour the enemy Chakra, but to knock Ding Kai's Devouring Chakra into the enemy's body.

Wait for the devouring chakra in the enemy's body to reach a certain amount.

Ding Kai can quickly seal away from the enemy, directly igniting the devouring chakra in the enemy's body, forming a sea of fire.

The power of this fire escape ninjutsu is that it is very secretive and cannot be detected except for the white eyes. And even if you detect it, unless you give up hand-to-hand combat, it will be difficult to defend.

Because it burns from the inside out, the enemy simply cannot extinguish it.

At this point, the A-level ninjutsu fire escape and dark prime-burning technique is completed!

More than a month has passed in a blink of an eye, and refined muscle lines have appeared visible to the naked eye on Ding Kai's body.

The whole looks thin, but it is full of strength. This is almost unthinkable for a teenager.

Ding Kai's physique, in this period of more than a month, has improved quickly enough to be frightening.

Especially in the first week, it was almost a leap of growth, and then it slowly entered a period of stagnation.

Rumble!!!

A punch blasted out, the air buzzed and exploded, and the mountain rock in front of Ding Kai was suddenly shocked and dense cracks appeared, and then exploded into countless pieces of different sizes!

"Hmmm! Now the power of my punch is comparable to one-tenth of that of Sakura, who cultivated the strange power in the original book. When she rescued Iro, she smashed a boulder several meters high and dozens of tons with one punch. And I, too, can break tons of stone. ”

"Even ...... Trees that are more than ten meters tall with a thickness of one meter can be smashed by me with a single punch with the Strange Force Flow Gluttonous Body Technique! ”

Looking at the damage caused by his full punch with satisfaction, Ding Kai nodded, but there was a hint of expectation in his eyes. I don't know, I added two hole cards, and I was able to defeat or kill an elite forbearance.

At this time, there were still two months left before the life-and-death duel between him and the black wolf.

During the time he was cultivating, the entire village was calm.

At least on the surface!

Ding Kai is not a retreat cultivation at all, and his ears don't hear anything outside the window.

During this month-long cultivation period, Ding Kai also completed a mission in Tuan Zang and killed a spy from an enemy country. That spy happened to be used by Ding Kai to verify the newly invented ninjutsu, the technique of fire escape and dark prime.

On the spot, a spy with special ninja strength was burned to death.

The concealment ability and power surpassed Ding Kai's accident, so it was designated as an A-level ninjutsu by Ding Kai.
