Kazama and Hizashi had already come to the room, gathered around the tunnel to observe the situation inside, this kind of darkness with no light at all was impossible to see anything clearly, Hizawa picked up the wooden plank that was dragged down by the shadow clone of Kazama, and flicked his fingers, the wind blade gushed out from his fingertips, and quickly slid across the plank, and the planks were cut into wooden sticks one by one, although it was very simple, but it was enough to use as a torch. Looking at the action of the sun slash, Kazama comprehended, picked up a wooden stick from the ground at random, and lit it with a flame, even if the wooden board without grease was dry enough, it was not easy to light, fortunately, the fire in Kazama was not an ordinary flame, and the flame made of chakra was much stronger than ordinary fire in terms of temperature and durability. The first torch has been lit, and Kazama took this torch to lead the second and third, and anyone who has ever made a fire in the wild knows that whether it is firewood, charcoal, or coal, the first one is the most difficult to light, and once the first fire is stabilized, it will be much easier to light the others.

Hand the lit torch in his hand to the sun, Kazama also left one in his hand, and threw the first torch into the tunnel, the wooden stick fell quickly, and the darkness in the tunnel was dispersed by the flames above the torch, and the situation below was suddenly seen clearly, the height difference is only more than 10 meters, compared to those trees in the forest, it is not as good as jumping down directly, and there is naturally no pressure at all, and the shadow clone of the wind will dissipate before because he can't see the bottom, and he doesn't know when to unload, The strength of the whole body is gathered on the legs, and naturally it can't withstand this huge force, and dissipation is an inevitable situation.

Hiza turned to look at Kazama, nodded slightly, and jumped down from the entrance of the tunnel first, as a teacher, of course he had to rush to the front, and wipe out all possible threats, Kazama watched Hiza's movements, and quickly squatted down and picked up all the wooden sticks on the ground, before reaching out to the entrance of the tunnel again. With the help of the dim light of the torch, Hizaki's face was still clear in Kazama's eyes, and seeing Sarutobi-sensei nodding at him, Kazama also jumped down from this entrance and landed lightly on the ground, and Kazama began to look at his surroundings. This tunnel is not very spacious, obviously the enemy is digging like this in order to dig more conveniently, after all, the soldiers are fast, looking at the tunnel of the black hole not far away, Kazama knows that this tunnel of more than 100 kilometers should lead directly to Konoha Village, at this time, those ninjas of Sand Hidden Village should all be preparing for a sneak attack on Konoha Village in the tunnel, and even the war may have broken out, leaving him and Sarufei Teacher not a lot of time.

"Teacher Ape Fei, let's take action...... "So far, there is no other good way to try the method other than flooding the Seventh Army, even if the two of them chase along the tunnel, it will take at least 20 minutes, and the speed in this not spacious tunnel will inevitably be affected, and when they rush back to Konoha Village, I'm afraid the war is about to end. Besides, even if the sneak attack on Shayin Village didn't start, what could the two of them do? Since the other party feels that the sneak attack on Konoha Village, which is guarded by Kazuma, it proves that the other party has at least one ninja who can compete with Kazuma, and Hizashi and Kazama rushing over can't just give away people's heads.

"It's up to you this time, Kazama, what do you think we should do?" At this point, Hinata had no choice but to put all the bets on Kazama, since he found out all these things, and the plan was also arranged by him, then let him arrange it.

"Let's take a look inside the tunnel first and see if the terrain is suitable...... Kazama said, and he walked into the tunnel with a torch, and Hizashi quickly followed him. Entering the tunnel, Kazama observed the tunnel left and right, since he and Sarutobi-sensei were able to survive in it, and the torches could also keep burning, it means that the oxygen in the tunnel is still relatively sufficient, and the vents will definitely exist, I just hope it won't affect his plans.

After a moment's hesitation, Kazama said to Hinachi, "Sarutobi-sensei, you can make a water balloon on the ground, I want to see where this tunnel goes......"

Hearing this, the sun slash directly threw out a water ball, which formed a smooth liquid surface after falling to the ground, and then began to flow slowly towards the other end of the tunnel, the height difference is definitely there, but it doesn't seem to be enough, you have to help it add a little force. "Teacher Ape Fei, if you use your best to perform Earth Escape, how long will it take to process this tunnel?"

"If you just change the terrain, it's still very simple, the main thing is to see how far away." Ape Fei Ri is the elite Shinobi of Konoha Village, and it is a bit too exaggerated to say that he can reclaim land from the sea, but there is still no pressure at all to transform the local terrain.

"That's going to be easy." As he spoke, Kazama ran towards the tunnel with Hizaki, estimating that he had run a distance of several hundred meters, before Kazama stopped, "Sarutobi-sensei, please make a solid wall here, you must ensure that the wall can block the flow of water, whether this plan can be successfully realized depends on the performance of this wall." ”

Hiza nodded, his face solemnly mobilized the chakra in his body, ready to do his best to cast the earth flow wall, before he began to seal, Kazama took the lead in speaking, "Wait a minute......" Kazama's hands were sealed, releasing a shadow clone, "Mr. Sarufei, do you have a detonation charm on your body?" ”

"Of course." The sealing scroll in Hichisaki's arms was like Doraemon's dimensional bag, and he could find anything he wanted, and he took out dozens of detonation charms from the scroll in one go, as well as more than 20 detonation charms connected to the kunai, which were obviously used for the mission. Kazama's shadow clone took these things and walked several times deeper into the tunnel, "Sarutobi-sensei, you can start ......"

"Do you want to block the water with a wall and wait until the water gathers enough before detonating the detonation charms and letting them spew out all at once?" If Hinata doesn't know Kazama's thoughts when he sees this, it's a little too stupid.

"Yes, as long as the water moves, the difference in height will increase their speed even faster, I hope those friends from Sand Hidden Village will like our gifts." Kazama was clearly very confident in his ideas, and after doing so, the power of the water flow was almost indestructible. It's just that Konoha Village may also be attacked by the water, but this is not a problem that Kazama can consider now, it is true to repel foreign enemies first, and dealing with the flood must wait for the village to settle down before thinking about it.

"Kazama, it's not that I discourage you, so much water is definitely not enough for my chakra alone, and besides, don't I have to use earth to renovate this tunnel?"

"Don't worry, I've found a very reliable water source, I don't need you to think about this problem, we should start work quickly when the time is urgent." Kazama didn't say exactly where the water came from, but just asked Hizai to start construction and build the wall as soon as possible.

Ri Slash's face was solemn, the chakra in his body stirred, and he completed the change of nature in his body, and quickly formed a seal in his hand, and a wall of earth spit out from Sun Slash's mouth, "Earth Escape, Earth Flow Wall!" ”

"Boom...... A heavy wall of earth appeared in front of Kazama, and he tapped the wall, but there was no feedback at all, and Kazama knew that this wall must be enough.

"Teacher Ape Fei, your job in the future is to use the earth to comb this section of the tunnel as much as possible, so that the slope of the tunnel is more obvious, so that the water will flow faster, as for the water source and the detonation charm, leave it to me and my shadow clone to complete!" Kazama ran down the tunnel towards the village, and Hizashi began to use the power of the earth to change the terrain in the tunnel. It seems to be very high-end, but in fact, it is just a chakra generated earth escape, slightly raising the ground in front of it, so that the entire tunnel shows a relatively obvious slope, and the master and apprentice are each engaged in their respective tasks.

The shadow clone left in the tunnel by Kazama stuffed the detonation charms that Hinata gave him into his arms, and only took the detonation charms with kunai, and in the center of the wall, he nailed the kunai into the wall one by one, and formed a circle with the kunai attached to the detonation charm, which was more stone than dirt, and it didn't have much effect to nail dozens of nails. The reason for this arrangement is because Kazama knows that these less than 100 detonation charms will definitely not be able to blow through the front wall, but the water pressure on the other side of the wall is very large, as long as a small hole can be made in the wall, then the entire wall will be completely destroyed under the action of strong water pressure, which is the reason why the so-called embankment of a thousand miles collapsed in an anthill.
