"Yuna, how is it, have I successfully connected with Xiaonan?" Masahiko asked.

Don't think crooked, this is a serious question, Masahiko has not yet reached the point of attacking a nine-year-old girl.

After returning to the country of vortex from Konoha, Masahiko first tested the cultivation of the two disciples, which focused on checking the production speed of Xiao Nan's detonation talisman, and finally was pleasantly surprised to find that Xiao Nan could basically make one in a few seconds, which could reach mass production.

But Xiao Nan doesn't have the bloodline of the Uzumaki clan after all, although the strength can be regarded as a middle ninja, but the amount of chakra is not enough after all, and Masahiko can only take her to find Yuna and want to solve it through technology.

Of course, Masahiko also thought about doing to Tsunade when he was in the ninja joint entrance examination, using the sealing technique to seal Chakra on Xiao Nan's body. But after trying, Xiao Nan's detonation charm is very unstable, after all, it is mixed with Masahiko's chakra.

After finding Yuna, the scientist really had a lot of ways, and after collecting the chakra samples of Masahiko and Xiaonan, he was able to convert the chakra transmitted by Masahiko into the same kind of chakra as Xiaonan through some kind of equipment, and Masahiko couldn't figure out the principle at all, and after shielding the chakra bracelet, another big black technology was generated.

"Grandpa Masahiko, it's connected." Yuna's voice replied, "You try to output a little chakra, not too much. ”

Masahiko did as he said, and Xiao Nan on the other side showed a slightly painful expression, Masahiko was startled and hurriedly stopped.

"Yuna, what's going on? Failed? ”

Yuna walked over with a smile, "It's a success, Grandpa Masahiko." However, Xiao Nan's chakra in her body is not lost now, and it will definitely be a little uncomfortable to receive your chakra again, it doesn't matter, it will be good for her. ”

Masahiko was stunned, nodded in understanding, and smiled.

"In this way, Xiao Nan's chakra volume may make some progress, and it will be an unexpected gain."

"But Grandpa Masahiko," Yuna continued, "After the instrument is transformed, your chakra will probably lose fifty percent of ......"

Masahiko waved his hand and interrupted Yuna's words, "It's okay, it's normal, five achievements are enough." ”

Then he turned to Xiao Nan, "Xiao Nan, no problem." Get used to it first, and then we'll start making the detonation charm. ”

"It's okay, teacher."

Within the next two months, Masahiko led Konan to make a detonation charm the next day, until he was stopped by Iko.

"Teacher......" Yizi's face was full of helplessness, "You have already made nearly 10 million detonation charms, and on average, the ninjas of the Vortex Country can get thousands of each, so you don't need to make any more." ”

Masahiko was stunned, only then did she know that two months of hard work had such great results, and looked at Xiao Nan opposite, her face was already full of exhaustion.

"Whew...... Then let's stop here for the time being, thank you, Xiao Nan. However, the hard work during this time has not been in vain, and your chakra amount has basically doubled, and the harvest is not small. ”

Xiao Nan nodded and smiled, and went to rest.

Masahiko didn't feel tired, and after having an immortal body, he never felt tired again.

"Yizi, since there are too many detonation charms, we can find a way to sell some."

This is the real purpose of Masahiko, the current economic source of the country of vortex is the country of thunder, but you can't always rely on the "protection fee" for a living, you must have your own economic resources.

Detonators are such a thing, the lethality is not big, but it is not small, and it is suitable for sale. As for the object of sale, the country of thunder probably doesn't have spare money to buy, and the country of water is a little too close to the country of vortex, so there are only the country of fire, the country of wind and the country of earth. As for those small countries, Masahiko probably won't have the money to buy them in large quantities.

But how to sell it is a problem. Konoha Village is easy to say, not only close but also has a good relationship, and there is such a thing as a detonator, which village doesn't want to have more. But both Sand Hidden Village and Iwa Ninja Village are a bit troublesome, not only because they are far away, but there are also many countries that they pass through in between, and they are prone to danger.

Iko asks this question, which makes Masahiko fall into thought.

"What if you go by sea?" In the past few years, the country of vortex has developed rapidly, and it already has ships that can sail far away.

"At sea?" Iko was stunned, "You can only reach the land of water from the sea, right?" ”

Masahiko frowned, speaking of which, he hadn't paid attention to whether the Hokage World was a circle or not, and if he could reach Iwa Ninja Village from the sea, the Sand Hidden Village would be much safer.

"I'll go out." Masahiko confessed and flew towards the southeast of the Vortex Country.

At the beginning, Masahiko reclaimed the sea, but only used ninjutsu to extend a large distance from the inland to the sea, and did not say that the entire ocean was filled, it was not a half-moon effort, and Masahiko would have to spend nearly a year at least.

Therefore, the southeast of the country of vortex is still an endless ocean, and Masahiko did not stop at the seashore and walked directly across the sea.

"This distance ......" Half an hour later, Masahiko frowned, there was still an endless ocean in front of him. At the speed of his flight, he had already crossed about two hundred kilometers.

"Is it so far?" After another half an hour, Masahiko finally discovered the continent, but not the New World.

"Is it really the land of earth? That is, the Hokage world is also round? Masahiko breathed a long sigh of relief.

"This distance, it takes about half a month to get here from the sea of the Vortex Country, which is about the same as transporting it on land, but it is much safer at sea."

Masahiko didn't go around the land of earth, he had already turned around when the shadow clone was looking for Yuna before. He was also in no mood to go to Onoki to catch up, so he turned around and flew back.

However, this time his speed was not fast, and every few minutes, he had to stop and erect a stone monument 100 meters high with earth, in order to prevent the people from losing their way on the sea.

It wasn't until the sky was completely dark that Masahiko returned to the country of the vortex and found Yiko in a hurry.

"Yizi, the world is really round!"

Yizi was stunned for a moment, not understanding what it meant.

Masahiko went on to explain, "It takes about half a month to sail from the southeast of the Vortex Country to the Earth Country, and you can issue a mission in the country to have the ninjas escort the Detonation Charm. ”

After thinking about it, Masahiko added, "This mission is positioned as S-level, at least two or more elite Shangninas must lead the team, after all, there may be some emergencies at sea." ”

Iko nodded, "Then the negotiation with Iwa Shinobi Village ......"

Masahiko smiled, "The first time I went with a ship, I haven't felt the feeling of sailing on the sea for so many years. ”

"I marked the route so that the people would not get lost, and this route could be called silk...... Uh, the path of the detonator. ”

nodded, Masahiko was very satisfied with his ability to name himself.
