"Crackling, crackling" Under the flames produced by the Uchiha Itachi after the shattering of the fireball technique that was maintained at the expense of Chakra, the scorching high-temperature flames generated by the small and dense dark red flames gradually turned red, dark red, and bright red at a speed visible to the naked eye. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

"It should be almost. After a dozen breaths, looking at the entire red stone wall, there were some stars dotted in the stone wall, and after the Uchiha Itachi gasped lightly, he decisively cut off the chakra's maintenance

Then, before the rootless flame was completely extinguished, Uchiha Itachi once again formed a handprint with both hands.

"Water escape ~ the art of water dragon bullet. ”

With the agitation of Uchiha Itachi Chakra, in the already humid environment around him, a large amount of water vapor suddenly gathered and a large amount of Chakra paid by Uchiha Itachi himself formed a huge water dragon in the blink of an eye.

As an elite educated in a serious ninja school, Uchiha Itachi not only has strong actual combat effectiveness, but also has a lot of cultivation knowledge and skills, and even the auxiliary knowledge of the side door is also very proficient.

In addition to music classes, which cultivate the spiritual realm, there are physics and chemistry subjects that explain the basic rules of power and mechanics of the world, as well as the action of energy.

For ordinary people in this world, this kind of subject knowledge, no matter how well they learn, will not be of much use, because it is difficult for them to apply that kind of phenomenal power without mastering the extraordinary power, because they have not mastered the power to pry the initial starting point.

But the people who have cultivated the Chakra Yuan Qi are different, whether it is the extraordinary Chakra Amplification Power, or the supernatural power formed after transforming into the Five Elements Ninja, it can be used as the starting point key to pry the rules of those phenomena.

In the eyes of Uchiha Itachi, although this knowledge is not as intuitive as directly cultivating various ninjutsu secret arts, through learning them, he can have enough understanding of the basic phenomena and rules of this world, and although these understandings cannot provide direct power, they can be used by humans in battle or when needed.

At this time, under normal circumstances, unless Uchiha Itachi used the hole card of the bloodstain limit to use the heavenly fire that would definitely exceed the time that his body could bear to burn the stone wall, otherwise he lacked powerful lethal ninjutsu and means, and it would take him a long time and strength to break this hard stone layer more than a foot thick.

But what he lacks most now is time.

So as soon as this situation came to mind, Uchiha Itachi immediately thought of the basic knowledge of hot and cold physical expansion.

Sudden contact with high temperature under extreme cold, or sudden rapid cooling at extremely high temperature, will cause great damage to objects subjected to alternating cold and heat, and this direct damage to the subtleties inside the substance can even make most objects directly produce a brittle-like effect.

"Roar", the water dragon with the size of an ordinary elite demon monster snake roared out from behind the Uchiha Itachi, and rushed towards the already burned red stone wall.

After the water dragon approached, a large amount of water vapor carried by its own convergence collided with the residual heat in the scorching channel, forming a large amount of fog rising.

The next moment, the white mist rose, and the huge water dragon, which had not been affected much, crashed directly into the hard stone wall that had been burned red.

With a loud bang, the huge water dragon dispersed and turned into a flood of water and poured on the entire stone wall, making a loud noise.

A huge mist of water evaporated, and at the same time, a low clicking sound reached the Uchiha Itachi's ears at the same time.

"It's done. Hearing the constant click, Uchiha Itachi chuckled.

The next moment, a shadow clone appeared, and under the insight of the writing wheel, Uchiha Itachi accurately observed the deepest and largest position of the crack on the stone wall.

The shadow clone leaped towards that location.

With the convergence of the shadow clone Chakra in mid-air, the right arm of the "Earth Escape ~ Rock Arm" continued to generate rock armor with a metallic luster, and the hard and huge Shi Kai wrapped the entire right arm of the Uchiha Itachi Shadow clone.

The rock arm belongs to the ninjutsu of Tu Dun, which uses chakra to create hard rock armor and attach it to the arm to increase strength and defense.

"Boom", the thick rock arm that made more than three circles of the rock slammed into the deepest part of the crack.

"Puff" was already cracking the stone wall, and was immediately blasted into it with a punch from the thick stone arm of the shadow clone.

"Shhh

"It worked. Looking at the corrosive liquid flowing from under his arm, the shadow clone Uchiha Itachi knew he had completed his mission.

"Bang" The next moment, the shadow clone automatically lifted the maintenance of ninjutsu.

"Hmm" At the moment when the Uchiha Itachi body received a little chakra return from the shadow clone, without the blockage of the shadow clone's right arm, there was a column of turquoise water that had just been blasted out by the Uchiha Itachi's punch.

Huge blue water shoots out like water pipes, and white pungent mist rises everywhere you pass along the way.

At the same time, a huge chain collision and a clanging sound suddenly appeared in the empty hole**.

………..

Back in time, when Uchiha Itachi had just come to the side of Bi Poison Tan and felt the position of the Oil Maiden Shizun through the sealing instrument medium on his forehead, the sturdy Oil Maiden Shizun, who was trapped under the Poison Tan by the Bishui Beast and bound with iron demonic energy chains, also felt the arrival of the Uchiha Itachi.

It's just that although he knew about the arrival of Uchiha Itachi at that time, he didn't have any way to help him, because he was trapped in the poison Tan and was completely relying on his own seal to protect himself, so he couldn't do anything superfluous at all, so he could only honestly wait for Uchiha Itachi's rescue.

If the Uchiha Itachi couldn't rescue him, then he would just stay down there and be in a hurry.

Of course, the oil girl Zhizun is not worried that the Uchiha Itachi will not find himself, because the seal ban was as early as the production of matching ninja equipment, and the oil girl Zhizun specifically involved the ability to sense each other in it.

Although he himself is limited by the chakra relationship, he can only feel the position of the other party's Chong at close range, but the Uchiha Itachi, who is not limited by this aspect, must be able to sense his own position from a distance.

Therefore, when he sensed the moment of the Uchiha Itachi, the oil girl Shizun knew that the Uchiha Itachi had come to save him.

"If you can go out with me, I promise not to call you the Raven for three days. In the golden chakra seal protective shield under the poisonous Tan, the oil girl Zhizun, who couldn't move all over, swore in her heart.

It didn't take long for a huge vibration to reach the ears of the oil girl Zhizun, and even brought a little bit of chain shaking.

"Is it Tu Dun?" thought to the oil girl Zhizun in his heart: "That's right, after all, Itachi doesn't have this ability to directly resist poison, so it is impossible for him to come down directly to save me from the beginning." ”

At the same time, although he knew that I was in the poison tank, he couldn't directly determine my situation through this poison tank, so using the earth escape to change the terrain and release the poison water was his only option. ”

However, just as the oil girl Shizun guessed the Uchiha Itachi's choice and then looked forward to the destructive power of the other party's earth escape, the huge vibration that kept approaching suddenly stopped and continued to approach after reaching a certain distance.

"What's going on? Could it be that there is something special around it?Or is there some special restriction that you can't directly use the earth escape to destroy this poisonous tan!"

Then, just as the oil girl Shizun wondered if there was an enemy coming to stop the Uchiha Itachi, a sudden burning sensation entered his feelings.

And after feeling the rapidly increasing scorching temperature and thinking of the vibration that suddenly stopped just now, the oil girl Zhizun just thought about it and scolded in his heart: "Damn, Itachi, have you forgotten that I am in it?"

"I'm not afraid to cook me first. ”

Although he cursed, at the same time, the oil girl Shizun also breathed a sigh of relief in her heart, because since the Uchiha Itachi continued to find a way to destroy the stone wall, it proved that the previous problem was with this poisonous tan, not the problem of the blue water beast or his men rushing back.

At this time, although the oil girl Zhizun didn't know that Iron Evil had been convinced, she even took the initiative to delay the footsteps and time of the blue water beast outside to buy time for the two.

But he can also imagine that the sudden departure of the Blue Water Beast and the just sneaking in of the Uchiha Itachi, in addition to the accident factor, it is more likely that the Uchiha Itachi took some means outside to attract the Blue Water Beast out, so as to sneak in to rescue him.

But no matter what the means, the Oil Girl Zhizun believed that if there was no enough bait to attract the Blue Water Beast outside, the Blue Water Beast that had been attracted out before would soon return.

"Itachi probably can't imagine my attraction to the Blue Water Beast!" Thinking of the extremely greedy look in the Blue Water Beast when he saw him after being brought here, the Oil Girl Zhizun felt his heart sink.

When he was caught before, the oil girl Zhizun was not completely unconscious, and he was also observing the enemy's lair along the way, but in addition to the outside waterway, since entering this underground space, this simple and extremely simple nest layout has been completely remembered by the oil girl Zhizun.

Except for a few simple spatial distributions in the middle to arrange slaves and men, as well as sundries, from beginning to end is a huge fucking passage, and in the end it is the lair where the blue water beast rests.

If the exit is blocked by the Blue Water Beast in this kind of terrain, then the Oil Maiden Shizun understands that he and the Uchiha Itachi will definitely not be able to escape.

Therefore, it is necessary to escape from this place before the blue water beast blocks the mouth of the lair cave to really escape.

It's just that at this moment, although the oil girl Zhizun is anxious in her heart, she can only hope that the Uchiha Itachi's arrangement can be better and faster.

Using the principle of thermal expansion and cold contraction generated by the rapid alternation of fire and water to attack the physical defense, the defense of powerful demonic creatures is a classic tactical method advocated by the ninja school.

Its advantages are not only that it has powerful destructive power, but it can also produce powerful effects that far exceed those of ordinary ninjutsu.

What's more, this tactical application is perfect for multiplayer co-op battles between newcomers, so it's widely loved by ninja school teachers.

Sure enough, it didn't take long for a huge howling beast roar to reach the ears of the oil girl Zhizun through the thick stone wall when tiny bubbles began to bubble up in the hot venom.

"It's the art of water escape ~ water dragon bullet. Oil Girl Zhizun guessed with certainty in her heart.

The next moment, there was a loud bang, a huge sizzling sound, even the thick stone walls and viscous venom could not be completely stopped.

"Here we go. "Being inside the poisonous tan, the moment the crack on the stone wall outside the poisonous tan appeared, the oil girl Zhizun clearly felt the cracking sound produced after the stone wall cracked.

However, just in the happy mood of the oil girl Zhizun, a loud "boom" first came, and then when the venom from the outside world sprayed out like a water gun, the oil girl Zhizun also felt the pulling sensation of the venom around him that was originally like stagnant water.

"Is it broken?" Feeling the pulling force around her, the oil girl Zhizun knew that the poison Tan had been leaked, and she was about to break free from here.

Sure enough, with the jet of the poisonous Tan water column, the hard stone wall that was already full of cracks was centered on the position where the Uchiha Itachi Shadow clone had just blasted out, and the tiny cracks quickly extended in all directions.

Because of the huge water column, the cracks expanded, and the turquoise poisonous water continued to leak out of those cracks, and then the corrosive and highly toxic pool water naturally corroded these substances whose corrosion resistance had not yet reached the peak, so that the cracks that had already appeared were still gradually expanding.

The result of the combination of the two is that the turquoise water column expands at a speed visible to the naked eye, and at the same time, the entire stone wall is driven to collapse.

In the Bi Poison Tan, feeling the faint loosening of the demonic iron chains around him that were originally restricting his movements, the oil girl Zhizun immediately began to struggle with her hands.

......With the leakage of venom, the iron chain fulcrum that was originally fixed on the stone wall also lost its restriction on the oil girl Zhizun with the broken and detached stone wall blocks.

After five or six breaths, when the turquoise water column also began to shrink, there was a sudden "bang" loud sound, and a cracked stone wall suddenly sunk in.

Through the hollow gap, you can directly see that there is a golden ball surrounded by countless iron cables that is shaking violently.
