The Ten Fists Sword is different from ordinary swords in that it has no entity, but a gourd-like energy form. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Therefore, the things that can be added are basically not entities, but special energy bodies or energies.

It's not easy to get these energies to come together.

After special integration, it is necessary to exert its own efficacy and role.

Only people who have a deep understanding of these energy combinations can upgrade and strengthen the Ten Fist Sword, and Uchiha Mikoto happens to be the one who knows the Ten Fist Sword very well, so the Ten Fist Sword will be handed over to her back then, because she is the only one who can upgrade the Ten Fist Sword.

And now Sasuke has just found two materials to upgrade the Ten Fist Sword, as long as he incorporates these two materials, he can make the power of the Ten Fist Sword even greater.

These two materials are: the power of space in the space quartz and the power of time in the dragon vein essence.

If you want to integrate these two powers into the Ten Fist Sword, you have to do it at the same time.

Now Uchiha Mikoto holds the refined power of space in his hands, and Sasuke holds the refined power of time in his hands.

The two of them were sweating profusely preparing for the final fusion, wanting to succeed in one fell swoop, because there was only one chance, and if they failed, the energy in the Ten Fist Sword would be out of balance, and the unbalanced Ten Fist Sword would be completely scrapped, and even a big explosion would occur.

So now what Sasuke and Uchiha Mikoto are doing is no different from playing with their lives, it's really exciting.

"Three...... Two...... One, let's go!" Sasuke and his mother counted down at the same time, and then poured the power of time and space into the gourd of the ten-fist sword at the same time.

It's not just about injecting it inside, it's about controlling the fusion of energy inside.

This is something that only Mikoto Uchiha can control.

Sasuke won't, but it doesn't matter, Sasuke directly uses the Sharingan to control the fusion of energy according to his mother's technique.

It's a process that takes a lot of energy, and without Sasuke's assistance, Uchiha Mikoto alone wouldn't have been able to do it alone.

This time, it took a full three hours to upgrade the Ten Fists Sword.

After the upgrade, Sasuke and his mother were sweating profusely, and their mental and physical strength were almost exhausted.

Thankfully, it worked. Sasuke had palpitations, and he almost couldn't keep up with his mother's rhythm just now, but fortunately, his mother returned and regained control of the rhythm.

As soon as the refining was completed, Kusanagi Sword Misaka immediately let out a voice and said, "Congratulations, master! ”

Sasuke said disapprerovingly: "Of course it's amazing, I don't want to think about how much the materials I added, 300 million! This is still cheap to buy at Kazama's house, if there is no billion in the black market, don't think about it." ”

"It's a pity that there is no sword soul. Kusanagi Kenmisaka's voice was a little regretful.

"Sword Soul?" Sasuke wondered.

Uchiha Itachi said proudly: "Yes, just like me, people who have cultivated the soul secret art can only become the sword soul of the Kusanagi Sword after death. ”

Sasuke said with some disdain, "The sword soul doesn't seem to be useful except for talking!"

Kusanagi Ken Misaka said exaggeratedly: "Ah, master, how can you say that, I have received 10,000 points of damage. ”

Seeing his pale mother, Sasuke unceremoniously said to Kusanagi Ken Misaka, "Okay, you can be quiet for a while." ”

Sasuke stood up with difficulty, came to Uchiha Mikoto's side, and said, "Mom, are you okay?"

Uchiha Mikoto collapsed a little, and said weakly: "It's okay! I'm just a little tired, I want to go home and take a shower, it's really uncomfortable not to take a shower for three days." ”

Sasuke nodded and said, "Okay! I'll take you back right away with the Flying Thor." But before I do that, I'm going to say goodbye to Old Man Gulicang. ”

It would be rude to use someone's refining room for a month and say goodbye, so Sasuke had to say hello to the other party before leaving.

Mikoto Uchiha, who was resting on a stool, said, "Go ahead! I'll take a rest first." ”

Sasuke gritted his teeth and cleaned up the refining room, before leaving the refining room, and when he came outside, Gu Li Cang stood outside and walked around anxiously, and when he saw Sasuke coming out, he stepped forward with great joy and asked:

"Sasuke-sama, how is the Kusanagi Sword you refined, has it succeeded?"

Sasuke was sincerely grateful, "It worked, thank you for letting us use your refining room." ”

Gu Li Cang touched his pale beard and said, "Thank you, you're welcome, hehe! The scrap you refined made made me a lot of money." ”

"Alright, Uncle Guli Cang, let's go back first, goodbye!" Sasuke beckoned to Guli Cang and returned to the refining room.

Sasuke walked up to his mother and said, "Mom, let's go!"

"Hmm!" Mikoto Uchiha nodded.

Sasuke used the Flying Thunder God, and the two of them disappeared in the refining room.

Gu Li Cang walked into the refining room and was a little surprised to find that there was no trace of Sasuke and Uchiha Mikoto!

What about people, when did they leave?

But Guri Cang doesn't have to worry about anything, Sasuke and Uchiha Mikoto are both people with great status, and nothing usually happens in Konoha.

Now that Sasuke and the others are gone, this place has become the territory of Guri Cang.

Gu Licang said excitedly: "Finally, it's my turn to refine the weapon, but I have learned several tricks, and I want to try it." ”

Gu Li Cang began his brand-new refining forbearance equipment, and his level was greatly improved.

The Uchiha clan's residence, Sasuke's home, spatial fluctuations are fleeting.

Sasuke and Uchiha Mikoto showed up at home.

"It's finally back!" Uchiha Mikoto, who was still dying just now, suddenly became energetic again, as if this home could give her infinite strength.

"I'm going to take a shower first, Sasuke, do you want to come with your mother?" asked Sasuke with a smile on the face of Uchiha Mikoto.

Sasuke blushed and replied, "No, Mom, I'm grown up." ”

"Hee-hee, what a bad kid, I'll wash it first. Uchiha Mikoto found clean clothes and entered her bathhouse.

Seeing his mother leave, Sasuke excitedly checked his results this month, nine Kusanagi swords, but only nine were successful, but it was a pity that so many materials were wasted, Sasuke originally thought that he could refine more than a dozen, but he didn't expect that the success rate was only half.

This is still the case of the first three with the help of his mother, after Sasuke started to refine it himself, his mother watched coldly and stopped saying a word.

Later, as long as my mother helped, the success rate would increase greatly, but my mother told Sasuke that if you want to be on your own, you can't rely on others.

This kind of truth is taught by Uchiha Mikoto, but Sasuke still pretends to be teachable and modest.

It made Uchiha Mikoto very happy.

Sasuke placed all nine Kusanagi swords on the ground, which were: Zero, Blue, White, Zhu, Xuan, Sora, South, North, and Jade.

Because he was going to give his subordinate, Xiao, so he directly named it with Xiao's code name.
