"Yuna, how about it? Have I successfully connected with Konan?" Masahiko spoke in a question.

Don't think wrongly, this is a serious problem. Masahiko is not yet at the point of attacking a nine-year-old girl.

After returning to the Whirl Kingdom from Konoha, Masahiko first tested the practice of the two disciples, focusing on the production speed of Konan's detonation talisman. Finally, he was surprised to find that Konan could basically make one in a few seconds, which could achieve mass production.

But Konan does not have the bloodline of the vortex clan after all, although his strength can be considered a Zhongnin, the amount of chakra is insufficient after all, Masahiko can only lead her to find Yuna and want to solve the problem through technology.

Of course, Masahiko also thought about using sealing techniques to seal the chakra on Konan's body like what Tsunade did during the joint examination at the time. But after trying, Konan's detonation talisman was made very unstable, after all, Masahiko's chakra was mixed with.

After finding Yuna, scientists did have many ways. After collecting chakra samples from Masahiko and Konan, they were able to convert the chakra transmitted by Masahiko into the same chakra as Konan through some equipment. Masahiko couldn't figure out the principle at all. After blocking the chakra bracelet, another big black technology was produced.

"Grandpa Masahiko, the connection is complete." Yuna's reply came, "You try to output a little chakra, don't be too much."

Masahiko acted as she said, and Xiaonan on the opposite side showed a slightly painful expression. Masahiko was shocked and stopped quickly.

"Yuna, what's going on? Did it fail?"

Yuna walked over with a smile, "It's successful, Grandpa Masahiko. But Konan's chakra is not damaged now, so it will definitely be a little uncomfortable to receive your chakra. It doesn't matter, it will be of some benefit to her."

Masahiko was stunned, nodded in understanding, and smiled.

"In this way, Xiaonan's chakra volume may improve and gain unexpectedly."

"But Grandpa Masahiko," Yuna continued, "After the instrument is converted, your chakra will probably lose 50%..."

Masahiko waved her hand and interrupted Yuna, "It's okay, this is normal, five is enough."

Then he turned to Xiaonan, "Xiaonan, no problem. Get used to it first, and then we will start making the detonating talisman."

"It's okay, teacher."

Within two months afterwards, Masahiko led Konan to make a detonation talisman the next day until it was stopped by Yizi.

"Teacher..." Yizi's face was full of helplessness, "You have made nearly ten million detonation talismans. On average, each Ninja of the Vortex Kingdom can get thousands of them, so there is no need to make them anymore."

Masahiko was stunned. Only then did she realize that the two months of hard work had such great results. Looking at Xiaonan opposite her, her face was already full of fatigue.

"Huh... Then let's stop here for the time being. Thank you for your hard work, Xiao Nan. But the hard work during this period has not been in vain. Your chakra volume has basically doubled and you have gained a lot."

Xiaonan nodded and smiled, and went to rest.

Masahiko didn't feel tired. After having the immortal body, he never felt tired again.

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

This is Masahiko's real purpose. The current source of economic resources of the Euro Country is the Thunder Country, but we cannot always rely on "protection fees" to make a living, and we must have our own source of economic resources.

The detonation talisman is not very lethal or small, and is suitable for sale. As for the targets for sale, the Kingdom of Thunder probably has no spare money to buy, and the Kingdom of Water is a bit too close to the Kingdom of Whirlpool, so only the Kingdom of Fire, the Kingdom of Wind and the Kingdom of Earth are left. As for those small countries, Masahiko probably won't have enough money to buy in large quantities.

But how to sell it is a trouble. Konoha Village is easy to say. Not only is it close but the relationship is good, but it also doesn’t want to prepare more things like the detonation talisman. But Sa Hidden Village and Iwa Ninja Village are both troublesome. Not only are there a long distance, there are many countries passing through the middle, which are prone to danger.

Yizi raised this question, which made Masahiko fall into thought.

"What if you walk from the sea?" In recent years, the country of Vortex has developed rapidly and has already owned ships that can sail far away.

"On the sea?" Yizi was stunned, "You can only reach the Land of Water from the sea?"

Masahiko frowned. He didn't pay attention to whether the Naruto world is a round one. If he could reach Iwamnin Village from the sea, the Sand Hidden Village would be much safer.

"I'll go out." Masahiko explained and flew towards the southeast of the Whirlpool Country.

When Masahiko was reclaiming the sea, she only used ninjutsu to extend the inland into the sea for a large distance, and did not say that the entire ocean was filled. That was not a half-month effort, and Masahiko would have to spend at least nearly a year.

Therefore, the southeast of the Whirlpool Kingdom is still an endless ocean, and Masahiko did not stop by the sea and walked directly across the sea.

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

"Is it so far?" It took another half an hour, and Masahiko finally discovered the mainland, but not the New World.

"Is it really a land of earth? In other words, the Naruto world is also a round?" Masahiko breathed a sigh of relief.

"This distance will take about half a month to get here from the sea in the Vortex Kingdom, which is similar to transporting on land, but it is much safer at sea."

Masahiko did not go around the country of Tu. He had already gone around when the Shadow clone was looking for Yuna. He was not in the mood to find Onoki to reminisce about the past, and turned around and flew back.

However, this time his speed was not fast. Every few minutes, he had to stay and use soil escape to erect a stone tablet up to 100 meters high to prevent the tribesmen who were sailing at sea from getting lost.

It was not until the sky completely dimmed that Masahiko returned to Urino Country and found Yizi excitedly.

"Yizi, the world is indeed round!"

Yizi was stunned and didn't understand what it meant.

Masahiko then explained, "It takes about half a month to sail from the southeast of the Eddy Country to arrive at the Land of Earth. You can issue missions in China and let the ninjas escort the detonation talisman."

After thinking about it, Masahiko added, "This mission is positioned as a S-level. At least two elites, Uenin, must lead the team. After all, there may be some emergencies at sea."

Izi nodded, "Then the negotiations with Iwa Ninja Village..."

Masahiko smiled, "The first time I went with the ship, I have not felt the feeling of sailing on the sea for so many years."

"I made marks on the route so that the tribesmen will not lose their direction. This route can be called silk...uh, the road to detonation talisman."
