A knock came at the door. "Yuying, are you in?" Recognizing Tobirama Senju's voice, Itō Yuying hurried to open the door and let him in.
"Teacher, did you need something?" Tobirama Senju said, "Nothing, I just came to check on your mental state. Mm, you've recovered fairly well. Have you been feeling especially mentally exhausted?" Itō Yuying scratched his head. "Yes, I keep getting sleepy." "Mm, rest properly for a few more days and you'll be fine. All right, let's talk business. I'll be going back in a few days, so I'll spend these next few days teaching you how to sense space properly." "All right, Teacher." "Fortunately, I left a Flying Thunder God Formula on you. When you activated it, I was able to rush over quickly. You need to work hard on your training, too!"
"Yes, Teacher. Oh, Teacher, how is the cultivation of the Senzu Beans coming along?" At the mention of this, Tobirama Senju deflated. He shook his head. "Still no success." Itō Yuying said, "Please wait a moment, Teacher." He then ran over to his backpack and pretended to search through it, while actually exchanging for Ultra Divine Water through the system. After a while, Itō Yuying said happily, "Found it!" Holding a small bottle of Ultra Divine Water, he came up to Tobirama Senju. "I found this while sorting through my parents' belongings. It's called Ultra Divine Water, and it's used to water Senzu Beans." In fact, what Itō Yuying had exchanged for was a stripped-down version of Ultra Divine Water. It could only water Senzu Beans; all its other functions had been removed. Most importantly, it was cheap.
Looking at the little bottle in his hand, Tobirama Senju asked, "Does it work?" "I don't know. That's what my parents' letter said." Tobirama Senju said, "All right, I'll take it back and study it first." Looking at the little bottle in his hand, Tobirama Senju could hardly contain his eagerness to go back and study it immediately.
After saying, "Get some proper rest," he hurried out the door.
Itō Yuying was a little bewildered. Didn't he say he was going to teach me how to sense space? Why did he just run off?
Then Itō Yuying sat cross-legged on the bed, closed his eyes, and sensed space. Within his sea of consciousness, he floated in the void. Everything around him was pitch-black. Itō Yuying used ki to sense his surroundings, and slowly, they began to change. It was no longer pitch-black. He sensed Might Duy doing pull-ups upside down. He could sense his breathing and hear his sweat dripping onto the ground, as clearly as if he were right beside him. Itō Yuying then sensed Jiraiya, who was outside Tsunade's room, peeping at her as she bathed. That sleazy expression-how did he even make a face like that?
Not wanting to look at Jiraiya's sleazy expression, Itō Yuying extended his perception to Tobirama Senju's room. To his surprise, Orochimaru was there too, discussing something with Tobirama Senju, who nodded repeatedly. Then he patted Orochimaru on the shoulder, took some scrolls out of his ninja tool pouch, and handed them to him. Orochimaru thanked him excitedly over and over before happily leaving Tobirama Senju's room. From Tobirama Senju's satisfied expression, it was clear that Orochimaru had given him quite a surprise.
Itō Yuying checked on the others as well. Within his sea of consciousness, he also sat cross-legged in the void. How can I move to their side? He reached out to touch the void, and a repelling force prevented his hand from moving any farther forward. Could this be the space barrier? But the notes Tobirama Senju gave me didn't mention this! Put simply, the Flying Thunder God Technique allows movement by sensing the space coordinates you leave behind. But how did he break through the space barrier?
Ah... In a flash of inspiration, he suddenly remembered Tobirama Senju saying that when he first began sensing his own Flying Thunder God Formula, a force blocked him. Then he had poured chakra frantically into the location where he had placed the formula, slowly feeling himself draw closer and closer to it, until he touched the formula he had set. In what felt like an instant, he arrived at the location of his formula several kilometers away.
In fact, once you sensed the Flying Thunder God Formula you had placed, you were halfway there. You and your Flying Thunder God Formula were right across from one another, close enough to touch, but the dimensional wall between you had to be opened with powerful chakra. Once you had opened it once, sensing and breaking through that space barrier became easier afterward. But it consumed too much chakra at first, so Tobirama Senju had gradually refined it until it reached its current state.
Itō Yuying used ki to sense Might Duy's presence next door, and an image appeared before him. At that moment, Might Duy was doing one-handed push-ups. Focusing intently, Itō Yuying gathered a large amount of ki and sent it surging toward the image of Might Duy. In the real world, Itō Yuying was already drenched in sweat, his lips pale, as weak as someone who had been gravely ill for days. After a while, tiny white points began darting around his body, growing more and more numerous. Within his sea of consciousness, Itō Yuying continued sending ki into the image.
At this moment, Tobirama Senju seemed to sense something. He quickly set aside his experiment, ran to Itō Yuying's room, and stood guard to keep anyone from disturbing him, muttering, "You have to succeed. You have to succeed." The others watched Tobirama Senju pace back and forth outside Itō Yuying's door, and he kept at it for five days. They repeatedly urged him to rest first, but Tobirama Senju refused them all. This was a crucial moment for Itō Yuying. From time to time, Tobirama Senju went inside to feed Itō Yuying some Senzu Bean Soup. He no longer tried to conserve Senzu Beans now. As long as Itō Yuying mastered Instant Transmission, Konoha really could do as it pleased.
It could transport many people and items without any distance limit. As long as you could sense the other person's ki, wherever you were, you could instantly arrive beside them. Even his own Flying Thunder God Technique had a distance limit. Just how awesome was that? Wasn't that khorosho? Wasn't that good? Watching Tobirama Senju mutter incessantly, Hiruzen Sarutobi and the others were very worried.
At this moment, within his sea of consciousness, Itō Yuying saw Tobirama Senju standing guard for him, and he also felt someone feeding him Senzu Bean Soup. Otherwise, he would have passed out long ago. He concentrated on using ki to break through the space barrier. Watching Might Duy train constantly in the image, repeatedly practicing the Energy Wave, Itō Yuying increased his ki output. Another twenty days passed. Tobirama Senju was almost like a stone wife waiting for her husband, pacing outside Itō Yuying's door every day, no longer even in the mood to shave his beard.
Itō Yuying watched Might Duy kick wooden posts, do push-ups, and walk on his hands. Then came a bang. The white points around Itō Yuying instantly converged in a frenzy before scattering again. As they scattered, Itō Yuying vanished from where he sat. Tobirama Senju also used the Flying Thunder God Technique and vanished. In the forest nearby, Itō Yuying could be seen straddling Might Duy's body. The scene was decidedly awkward.
Tobirama Senju came up to them as well. Without noticing their awkward position, he laughed heartily. "Excellent, excellent! Yuying, you haven't disappointed your teacher. Wonderful, wonderful!" In his excitement, Tobirama Senju jumped up and down on the spot. Itō Yuying was very happy too. With Instant Transmission, let's see who can catch me now. "Here, Yuying, this is the Sealing Technique. You know what to do." "Teacher, I've barely had time to warm up my technique!"
"Ah... Yuying, you're being narrow." "Narrow how?" Itō Yuying asked in confusion. "Narrow-minded, of course! Come on, write it down. Your teacher will check it in a bit. You can learn any of the Forbidden Techniques in there." Itō Yuying said nothing more and began writing down his insights and method. Tobirama Senju kept sneaking glances from beside him, nodding from time to time.
