Uchiha Kakashi
After receiving that Uchiha Bloodline Vaccine, Hatake Kakashi was no longer pure; he had Hashirama Cells and Uchiha Clan blood in his body, which meant he was on the path to evolving into the Otsutsuki Clan.
Kakashi sensed another ability within his body, seemingly Yin Release Chakra, and exclaimed in surprise, "Hokage -sama, I feel like my mental strength has increased again!"
Seeing Kakashi's slight panic, Qingcheng waved his hand, indicating that Kakashi shouldn't panic. He then said, "Quickly circulate your Chakra to let your body digest this power, and then try to control your Kamui Mangekyō Sharingan to see if you can shut Mangekyo down."
Kakashi immediately sat down on the ground and, as Qingcheng had instructed, began circulating his Chakra, then went to control his Mangekyō Sharingan.
Kakashi was also extremely shocked. After his body fused with this power, his left Mangekyō Sharingan consumed far less Chakra, and it seemed he could freely control the Kamui Mangekyo.
Kakashi then controlled his Kamui Mangekyo Sharingan, quickly transforming the Mangekyo pattern into Three-Tomoe Sharingan, and then the crimson Sharingan returned to ordinary black eyes.
Kakashi then asked with a surprised look, "Hokage -sama, my Mangekyō Sharingan is closed, but I still have a question: am I still considered Hatake bloodline?"
Qingcheng looked at Kakashi, who seemed doubtful, and said with a smile, "Then how about you call yourself Uchiha Kakashi?"
Kakashi quickly shook his head, then said awkwardly, "Hokage -sama, I'd better stick to my Hatake Kakashi. If I change my surname, the Hatake Clan will be wiped out."
Kakashi looked at Qingcheng's smiling face and said seriously, "Hokage -sama, you can go to Minister Zhang. He dreams of joining the Uchiha Clan. You have the technology, so give him a pair of Sharingan. Your Uchiha Clan will have another member."
Qingcheng looked at Kakashi's embarrassed face and said with a smile, "Shouhon Yihan fat and has big ears. I'm afraid he will affect the image of our Uchiha Clan. How about I change his name to Hatake Zhangben? Do you want this guy?"
Upon hearing Qingcheng's words and recalling Shouhon Yihan, Kakashi quickly shook his head and said, "Let's just forget about it. This guy is too reckless. Let him continue being the head of the Police Force!"
Qingcheng looked at Kakashi's eyes, both of which were black pupils, making them a perfect match for Obito's. He looked almost identical to Kakashi in Boruto: Naruto Next Generations, both having black pupils; the only thing missing was a copy of "Icha Icha Paradise."
Qingcheng then said with a serious expression, "Brother Xiao Storm Release Kekkei Genkai? The process of cultivating the Kekkei Genkai is somewhat similar to Purple Electricity. Your body has Yang Release Chakra, which can be fused with Water Release and Lightning Release to generate the Kekkei Genkai and awaken the Storm Release Bloodline."
Kakashi looked at Qingcheng's serious face and thought to himself, "What should I do if I encounter a Hokage who's obsessed with training? I'm so afraid that the Hokage might create a Storm Release Kekkei Genkai Vaccine for me. Is my Hatake bloodline still authentic?"
Kakashi immediately said, "Hokage -sama, I'm willing to learn, I'm willing to learn. That way, you won't have to trouble yourself to make me the Storm Release Kekkei Genkai Vaccine."
Qingcheng looked at Kakashi's surprised face, then scratched the back of his head and said awkwardly, "How did you know that I was preparing to create a Storm Release Kekkei Genkai Vaccine? Were you spying on my privacy? You overstepped your bounds, Kakashi! You actually spied on the Hokage's privacy!"
Kakashi quickly shook his head, then said awkwardly, "Hokage -sama, I was just guessing. I saw it last time when you had Hyuga Hisaharu draw blood from Darui. I guessed you were planning to research Storm Release Kekkei Genkai Vaccine, but hearing what you're saying now, I know I was right."
Kakashi then said with a surprised expression, "Hokage -sama, please teach me quickly! I'm determined to learn it so you won't have to bother researching the Storm Release Kekkei Genkai Vaccine. If you do manage to research it, please give the opportunity to someone else. I would be extremely grateful."
After Kakashi finished speaking, he immediately waved his hand to indicate that he really could do it.
Seeing Kakashi's surprised expression, as if he was afraid of getting vaccinated, Qingcheng immediately scolded, "Kakashi, you've really gone too far! Tell me right now! Do you still need Assistant Hokage Chakra? Do you feel your kidneys are stiff? It's all because of you. And your Mangekyō Sharingan, can you turn it off?"
Kakashi looked at Qingcheng's stern face and immediately said with a wry smile, "Hokage -sama, please begin training in Storm Release Kekkei Genkai! Once I've mastered this technique, I'll teach it to many more people. I believe I can do it."
Hearing Kakashi's words, Qingcheng didn't waste any more time and immediately began teaching the Storm Release Kekkei Genkai.
Upon hearing the Hokage's instruction, Kakashi immediately began circulating his Chakra, first gathering Water Release Chakra in his hands. A flowing column of water appeared directly in Kakashi's palms.
Kakashi then channeled his Lightning Release Chakra, and crackling lightning crackled from his palm, which was still dripping with water.
Qingcheng observed that Kakashi's control over Chakra had reached its peak; the ratio of Water Release Chakra to Lightning Release Chakra was perfectly balanced—not too much, not too little. And the most crucial step was fusing the two Chakra natures.
Because Kakashi already had experience fusing Lightning Release when he trained in Purple Electricity, he was quite familiar with fusing other Chakra, but creating Kekkei Genkai was something he was completely unfamiliar with.
Qingcheng looked at Kakashi's hands, where the water and Lightning Release Chakra Chakra all stabilized, and then said, "Release all your Chakra, and then use your Yang Release Chakra to guide them to fuse. Once the fusion occurs, your Storm Release bloodline limit will be successfully achieved."
Upon hearing this, Kakashi immediately activated his Chakra, channeling High-level Kage -Chakra into his palm like a spring.
Then Kakashi used Yang Release Chakra to guide Water Release Chakra and Lightning Release Chakra, converging and fusing them to create a completely new Storm Release Kekkei Genkai."
About two hours later, the lightning and water in Kakashi's hand merged together, turning into a ball of blue light, as bright as lightning, yet as long and continuous as a column of water.
Kakashi immediately stood up, smiling, and said, "Hokage -sama, I succeeded! Thank you for your guidance. I am deeply grateful. I will definitely protect Konoha."
Kakashi thought to himself, "That was really dangerous. I've dodged another vaccine shot."
Looking at Kakashi's delighted face, Qingcheng smiled and said, "Storm Release Ninjutsu can use the hand seals of Lightning Release Ninjutsu or Water Release Ninjutsu. I also want to learn a few powerful Storm Release Ninjutsu."
Kakashi, seeing Qingcheng's serious expression, immediately said, "No need, Hokage -sama. The Scroll of Seals contains many Storm Release Ninjutsu. I'll test the power of Storm Release first."
After saying that Kakashi immediately began Hand Seals and shouted, "Storm Release: Lightning Dragon Sumo Technique!"
