The pitch-black ball, with a radius of about twenty to thirty centimeters and a shining metallic texture, roared through the air, causing sharp and ear-piercing sonic booms along the way.
In less than a few tenths of a second, the ball crossed a distance of hundreds of meters, hit the ground of the earth-and-stone test site with a loud bang, and was firmly embedded in it. Only half of its dark surface was exposed, glowing in the sunlight.
The cold light rises from the forest.
At the same time, the fierce collision also caused countless cracks to appear on the surface of the iron ball, and a stack of papers crammed inside could be faintly seen.
Immediately afterwards, as the ninja outside the field made seals with one hand and shouted loudly, the dark ball half buried in the ground began to glow with light from the inside out, turning red in an instant.
boom!
The sound waves exploded, the air pressure rose, and the wind blew away the remaining clouds.
Hundreds of detonating symbols were detonated at the same time, creating a powerful shock wave that swept all around, carrying countless fine iron pieces and rushing towards the nearby area. In just a moment, dozens of human-shaped hardwood targets standing within a radius of 30 meters were eliminated.
Crush and fly away.
Two or three hundred meters away, he was looking at the violent explosion caused by the detonating talisman shell, but he didn't want to see the billowing white smoke coming out of the place after the fire, which made him unable to see the scene inside clearly for a while.
Shifting his gaze, Lei Luo narrowed his eyes slightly and looked at a piece of hardwood fragments that were blown away by the target point more than ten meters in front of his feet. He saw that its whole body was covered with densely burned black holes, and some places were inlaid with various inlays.
Regular iron scraps.
He took a few steps forward and picked up the hard board. Based on the appearance analysis, Lei Luo felt that this should be the torso of the target. At this moment, due to the impact of the explosion, it looked like it had been eaten by countless ants.
It's so miserable that you can't even see its original appearance.
To a certain extent, even after being blown up like this, it can still maintain a certain degree of integrity. The quality of these high-hardness targets made of new composite materials is still quite good.
"This detonating talisman cannonball is quite powerful. How did you think of fusing the detonating talisman with iron sand?"
Orochimaru walked up to Lei Luo and was also looking at the fragments of the target in Lei Luo's hands. When he saw the countless small holes on it, he couldn't help but construct a picture in his mind of a human body being blown up by this thing.
That feeling must be extremely sour and refreshing.
"Using high-pressure gas combined with iron sand impact to cause secondary physical damage in addition to explosions will undoubtedly effectively increase the attack range of artillery shells..."
Throwing away the waste in his hand, Lei Luo glanced around and saw a lot of iron sand and target fragments scattered on the ground around him. He briefly estimated the distance and then said:
"Ordinary detonating talisman bombs use shock waves created by high-temperature and high-pressure gas to cause damage, but the detonating talisman shells used with artillery can increase the damage range from thirty meters to about one hundred meters."
"Hundreds of irregular iron pieces shot out at high speed can obviously turn the target area into a death realm. Under such a level of attack, if the Jonin does not take precautions in advance, he will be dead."
As Lei Luo talked, he recalled the scene when the detonating talisman cannonball had just landed on the ground. He waved to the several ninjas guarding the cannon. After they came over, he gave instructions:
"The measurement team must grasp the best time to detonate the detonating talisman shell as soon as possible, and strive to make it explode in mid-air near the target point."
"When a shell hits the ground, at least one-third of its power is wasted. Do you know that? You must know how far away the target is and how long it will take to detonate."
"Follow up, remember to compile an operation manual."
Seeing these technical workers and production ninjas, they all nodded. Lei Luo stopped talking. As soon as he turned back his eyes, he saw Orochimaru and others gathered around the artillery used for demonstration, facing this new weapon.
Pointing fingers:
"There seems to be a sealing technique on it."
"What is this device used for? It's a bit like a storage device."
"What does it store?"
"You can shoot the cannonball so far just by outputting chakra? What is the principle of this?"
Walking to the side of the artillery, Orochimaru and Beiliu happened to turn their heads and look at him with doubtful eyes. Lei Luo thought about it and waved to the group of bureaucrats who were following him:
"Uzumaki Koichi, you are responsible for this research and development, right? Come and explain it to Orochimaru and the others."
Uzumaki Koichi, the deputy chief of the Uzumaki clan who was over fifty years old and was the director of the industrial park department at the time, heard the words and came closer. When he reached behind the cannon, he squatted down and stretched out his palm to press the rear part, which happened to be on the bulge.
On the cylindrical bottom, there is a base engraved with dense sealing incantations.
"This technique has three functions. The first is to absorb and store the user's chakra. The second is to convert the stored chakra into a specific type of C-level wind escape for pressurization. The third..."
"When the energy intensity of this high-pressure wind escape reaches a certain critical value, the sealing technique will automatically release the valve and spray out extremely powerful gas. This is how the detonating talisman shells are fired."
"In addition, if wind attribute ninjas use artillery, the process of absorbing chakra can be greatly reduced. Furthermore, there are three absorption interfaces, which can allow up to three ninjas to input chakra into the artillery at the same time."
While patiently explaining the operating principle of the artillery, Uzumaki Koichi circulated the chakra in his body and concentrated it on his hands. Suddenly, through contact with the base, the sealing technique like a ghost painting lit up with cyan light.
Half a minute later, with a loud bang, the muzzle at the top of the barrel was seen, and the air in the area directly in front of it was distorted. At the same time, the howling wind also rolled up the clothes of the spectators.
The artillery trembled for a moment and soon became silent.
There was no explosion in the distance. Obviously, Uzumaki Koichi just fired a blank cannon to show the two illiterate people Orochimaru and Beiru the power of the sealing technique of the Uzumaki clan.
“What a breathtaking concept.”
Looking at the dimmed artillery base again, Orochimaru grinned unconsciously and praised it sincerely. He was thinking secretly in his heart: What kind of technical difficulties need to be overcome in order to realize the function of the artillery.
The first is the step of absorbing, which involves the ability to absorb a certain amount of chakra. The principle is similar to the Bagua seal that seals the tailed beast. The second step is to use sealing spells instead of hand seals to directly convert chakra into ninjutsu.
This ninjutsu must have been specially developed to cooperate with artillery.
The essence of wind is the flow of air. Even if Uzumaki Koichi didn't say what kind of development idea was used for the C-level wind escape, Orochimaru could guess that it was almost completely sacrificing the cutting and sharpness of the wind and making it thicker.
, as powerful as a typhoon.
Continuously input chakra and continuously convert it into wind power. Place the stored energy inside the base and pressurize it, pressurize it, and pressurize it again, until the extremely violent wind force can reach the point where the cannonball can be shot five kilometers away...
Then the third function of the sealing technique is to detect the energy intensity, release the output interface, and let the wind flow into the barrel to instantly push the detonating symbol shell forward at high speed.
