In a small courtyard rented by Zhang Yuan somewhere in the country of craftsmen, Zhang Yuan was assembling in front of Tsunade and Shizune, and he asked the blacksmiths of the country of craftsmen to make utensils.

As Zhang Yuan installed the parts one by one, a cylindrical object with a diameter of about one meter was finally formed, looking at this one-person-tall object, Tsunade couldn't help but break out in a cold sweat, this is the oversized weapon you said?

"According to what you said, the big fist can make no grass grow within a diameter of 30 meters, such a large one, if it explodes in Konoha, will Konoha not grow an inch of grass?"

"No, no. Isn't this still not filled with filler?

Without filler, just such an iron shell, how could he be in danger? ”

Zhang Yuan wiped the cold sweat on his forehead and said against his will.

"What is the filler?"

"Filler, this is a bit difficult to do", random Zhang Yuan popularized science to Tsunade, what radiation and elements are there, what great changes, what fission Listening to Zhang Yuan, who kept explaining, the spit was flying, and Tsunade was confused.

Although I think I'm better than you in terms of control, I don't understand what you're saying at all, but I can't pretend that I don't understand, so I can only nod my head there desperately, as if I understand it very well.

As Zhang Yuan finished explaining, he asked Tsunade, "Princess, do you understand?" ”

"Uh-huh, don't be strong, got it,"

So we start extracting those elements,"

"Uh, well, how do we extract it?"

"This princess, your strength is so great, then please hit this bucket of water,"

As he spoke, Zhang Yuan took out a bucket of water and handed it to Tsunade, and asked the Gang Gang to beat the bucket of water to turn it into heavy water, as long as it becomes seed water, you can extract those radioactive elements, and then Zhang Yuan took out some ores and oils he bought along the way, from which a part of the radioactive elements can be extracted, of course, the premise is that Tsunade must first make heavy water out of heavy water.

There were a few big question marks on Tsunade's forehead, but he didn't understand what this was, Zhang Yuan also explained it just now, but he didn't understand it, but Zhang Yuan emphasized that as long as he beat him, then he used his strength to punch this bucket of water, and the effect of splashing water did not appear in an instant, but the water instantly decreased by 1/3, looking at the lack of 1/3, Zhang Yuan was directly embarrassed, he didn't expect Tsunade's micro-control to be so strong, and he beat the water into heavy water with one punch.

"Tsunade-sama, you are worthy of being the most famous and strongest micro-gymnastics master in the cold world, and you have made the water so quickly?"

Watching Zhang Yuan say that he had made heavy water, Tsunade was there and laughing.

"It's a little meaning, it's a little meaning"

In fact, my heart is crumbling there, what is this? Why can't I feel these changes in the water? I just punched myself and became something different from the water I drank? Are you kidding me?

Just after Tsunade succeeded in beating the heavy water, Zhang Yuan was ready to extract radioactive elements, but thinking that the radioactivity of radioactive elements was harmful to the body, he immediately let the master extract it, after all, this guy is a medical ninja, and he is still very confident in the protection of this piece, even if he will be seriously necrotic of the body cells stimulated by radioactive elements, it doesn't matter, he has that kind of Baihao technique that can be recovered, and then after handing over the key steps of extracting radioactive elements to Tsunade, Zhang Yuan walked quickly with silence and hid outside.

Looking at Zhang Yuan and Mute who were hiding far away, Tsunade didn't wonder, could it be that these radioactive elements would explode when they were mixed together? As soon as he thought of the explosion, Tsunade's straight long hair immediately became an explosion head, "Zhang Yuan, you roll over for me,"

"Hey, what's the matter,"

Zhang Yuan ran to Tsunade and asked.

"Will these elements explode when they come together?"

"Yes."

"Then why do you want me to extract it?"

"Isn't this an extraction one by one?"

"And what about after the extraction?"

"After extraction, as I just said, this element is placed, and that element is placed there."

"Is that so?"

"That's right."

"Are you sure"

"I'm sure."

"Won't it explode?"

"I didn't put the fuse, how could it explode?"

"Didn't you say that these two elements exploded when they collided together?"

"Isn't that a partition in between?"

"Are you sure it's safe?"

"Absolutely safe,"

"If it's not safe?"

"There will be no ifs, you can rest assured."

As Zhang Yuan and Tsunade had a conversation there without answering, Tsunade finally let go of his anxious heart, in fact, he was thinking, if this weapon was really made according to Zhang Yuan's steps, even if Zhang Yuan accidentally died on the battlefield, Konoha had already mastered this production process, and could continuously produce this kind of weapon that surpassed ninjutsu and could cause serious and large-scale damage without launching a large-scale ninja attack.

As Tsunade followed Zhang Yuan's instructions, he extracted various radioactive elements step by step and put them into the shell of this nuclear bomb.

After placing it, Zhang Yuan came over and patted the nuclear bomb with satisfaction, "Not bad, Tsunade-sama, you are really a heroine among women", said and gave a thumbs up to the steel hand, and then took out the gunpowder purchased in the fire film and television industry and put it on the final lead.

Of course, the moment Zhang Yuan is doing is not a hydrogen: bomb, but an atomic bomb, which needs to be detonated with gunpowder, which causes these radioactive elements to undergo great changes after detonation, and then produces a powerful shock wave and radiation to destroy all targets within the attack range.

As Zhang Yuan put the gunpowder into the atomic bomb and turned off all the control switches, the Heavenly Court system prompted him to get a simple version of the atomic bomb, but Zhang Yuan didn't know how to detonate it now, should he throw it out and let him explode by himself? It's better to install a detonating device for him, but he doesn't have this thing, it doesn't matter if he doesn't have it, because there is gunpowder in the Hokage world, although their technology is a little crooked, and they haven't developed any strong gunpowder weapons, but the simplest explosive device still exists.

Thinking of this, Zhang Yuan installed an improvised explosive device on this nuclear bomb, and then looked at his finished product and nodded with satisfaction, with the successful manufacture of the first atomic bomb, Zhang Yuan, thinking that he was making this kind of play in a world where black technology is prevalent is really too enjoyable, since the first one has been manufactured, is it possible to make the second or even the Nth one?

Just when Zhang Yuan was triumphant there, Tsunade said coldly, "That Qimu Yuan, since the sample has been manufactured, let's explode one to see the effect?" ”

Hearing Tsunade's bold language, Zhang Yuan instantly shuddered, "Princess Tsunade, don't want it,"

"Why?"

"After all, this is not a joke", if this bomb explodes, Zhang Yuan gestured to the atomic bomb standing next to him, and then said to Tsunade, "This is enough to blow Konoha into the sky." ”

"What? You really didn't feel good. Such a big thing, you have to bring back Konoha, and an explosion will blow up the wood industry to the sky and say, what are you aiming for? ”

"No, no, princess, didn't I enhance the Konoha heritage?"

"You used to be strong in Konoha, but if you bring this thing into Konoha, won't it bring a bigger crisis to Konoha?"

"Then why don't we put it in the Seal Scroll?"

"Ali? That's right, if you put it in the Seal Scroll, it won't be detonated, especially in the Seal Scroll, time is completely still,"

This is something that all ninjas know, no matter what collision he encounters, as long as he doesn't break the seal, he won't fall out of the contents inside, even if this one seal scroll is damaged.

"Then Zhang Yuan, why don't we make a slightly smaller release and see the effect of the fireworks?"

This big one can't be released with such a big lethality, so Tsunade suggested that Zhang Yuan make a slightly smaller one next to him, in fact, the master suggested that Zhang Yuan release a fist-sized nuclear bomb in his hand, but Zhang Yuan didn't agree, after all, it can be launched remotely, and this nuclear bomb can only be placed in a fixed place for detonation, except for the Tsunade who has great power, it can only be placed in a fixed place for detonation, thinking of the one Tsunade said to make a small Zhang Yuan thought that it was okay, after all, after making a small one, He can also use energy to attack, knock this nuclear bomb out, and then shake it to detonate, which is also a good choice, and then Zhang Yuan nodded, "Okay, then let's build a slightly smaller one." ”

Then two days later, the small nuclear bomb device built by the blacksmith of the country of their new craftsmen has been ready, after the simple and skillful extraction of radioactive elements by the mobile phone, Zhang Yuan's placement of the explosive fuse and other items are completed, a nuclear bomb the size of a basketball is freshly baked, looking at the freshly baked nuclear bomb that is not the size of a basketball, Zhang Yuan is heart is excited to jump out of his body, after all, the attack power of such a small nuclear bomb is no longer comparable to the tailed beast jade, after all, this is a nuclear weapon that is just right, even if she is a little smaller, but the yield of the attack is also very strong, of course, it must be stronger than the nuclear weapons of the Galaxy Clan, after all, the Galaxy Troopers have launch vehicles and other places, and there is only a little bit of nuclear weapons in them, that is, the size of peanuts at most.

After the production of this basketball-sized nuclear weapon, Zhang Yuan couldn't withstand Tsunade's constant temptation, and regardless of the fact that it was dark, he came directly to the field from Tsunade, ready to detonate this one and five, but after they went out from the country of craftsmen where they lived, they walked dozens of kilometers before they chose a place to detonate nuclear weapons, after all, Zhang Yuan kept exaggerating how nuclear weapons were there, uh power, but Tsunade never believed it, but if this thing was real, what should I do, it would not stop, As Zhang Yuan walked out, and finally 50 kilometers away from the country of craftsmen, they chose a canyon, ready to test the power of this nuclear weapon in this canyon, and then placed this nuclear bomb here, Zhang Yuan made a simple timing device, that is, half an hour later, this nuclear weapon will be detonated, looking at the Tsunade who could not observe and Wu detonate at close range, he was very unhappy to say to Zhang Yuan, "Qimuyuan, why should we set for half an hour?" Wouldn't it be possible to detonate now? ”

"Ah, Princess, it is estimated that the explosion of a few of us will be wiped out in an instant,"

"Is that an exaggeration?"

"It's such an exaggeration, you won't lie to me, will you?"

"No, no, no"

"You can't be stolen from here, can you?"

"No, no, aren't we going to bury it in the ground?"

In the process of their non-stop bickering, half an hour passed, and they also stayed away from the place where the nuclear bomb was planted, dozens of kilometers, seeing that the time was almost up, Zhang Yuan reminded a few people to wear goggles, and then looked at the place where they planted their nuclear weapons.

Soon a pillar of light appeared through the sky, but this set of pillars of light flashed away, and a random orange-red mushroom cloud rose into the sky where the pillar of light appeared, although the scale was not very large, but seeing such a gorgeous fireworks in the distance, Tsunade couldn't help but say, it's really beautiful.

Hearing Tsunade's explanation, Zhang Yuan also broke out in a cold sweat How big your nerves are, now I only know that it is good-looking, didn't I think that such a good-looking and gorgeous fireworks need to be so powerful? Just after a few people watched the orange-red mushroom cloud rise into the air, a strong shock wave came near them, but this shock wave is no longer the kind of shock wave that is closest to the range that ordinary people can bear, even if it is like a hurricane that suddenly appeared, although the body shook slightly, but it did not affect them to stand in place and continue to watch, feeling the gust of wind that came from the impact, Tsunade converted there, if there was such a strong wind 30 kilometers away, So how big is the summit ten kilometers ahead, how big the wind will be ten kilometers further on, and how strong is the wind at the place where the explosion is blowing, and the mouth of an olive can be plugged open so big a circle appears on the face of the hand.

Tsunade Mulan turned her head to look at Zhang Yuan, "What you said is true?" ”

"I'm telling the truth."

"Why didn't you say it earlier?"

"Didn't I say it all the time?"

Tsunade was speechless in an instant, yes, Zhang Yuan had already said it, but he didn't believe him all the time, and even if he did, he barely convinced himself to believe it.
