Injecting Kakashi with the Vaccine

Kakashi and his entourage of Anbu Ninjas, along with a large group of civilian ninjas, all knelt on one knee upon seeing Qingcheng's arrival, and respectfully greeted him, "Fifth Hokage, you've returned!"

Kakashi, looking exhausted, said, "Fifth Hokage, I have placed a large number of B-rank Ninjutsu and C-rank Ninjutsu in the training room as you requested. Today, 532 people have come here to choose Ninjutsu."

Upon hearing Kakashi's report and looking at Kakashi's weak and listless appearance, Qingcheng shook his head, thinking to himself, "Kakashi is still being held back by Obito's eyes. If it weren't for this Mangekyō Sharingan, Kakashi would have reached Kage Level strength long ago. The reason he's stuck at Quasi-Kage Level and can't break through is simply because he doesn't have enough Chakra."

Qingcheng looked into Kakashi's eyes again, thinking to himself, "This Mangekyō Sharingan is constantly consuming Chakra. Kakashi isn't from the Uchiha Clan, so he can't turn it off. I need to use the power of technology to help Kakashi take another step forward."

Then Qingcheng said with a serious expression, "Minister Kakashi, come with me for a moment, I have something to tell you."

Upon hearing this, Kakashi's tired expression vanished, replaced by a serious one, and he followed Qingcheng into the Hokage's Office.

After Kakashi entered the Hokage's Office, the Anbu Ninja outside immediately reached out and closed the Hokage's Office.

Kakashi looked at Qingcheng's Sharingan staring at him and thought to himself, "Could it be that the Fifth Hokage is preparing to take back this Sharingan? This is a relic entrusted to me by Obito. I must protect it well. Even if I overstep my bounds, I cannot return it."

Kakashi then said with a serious expression, "Fifth Hokage, although this eye is the Sharingan of the Uchiha Clan, it was entrusted to me by an old friend, and I will not return it."

Seeing this, Qingcheng shook his head and said seriously, "That's not what I meant. This Sharingan is constantly consuming your Chakra. Your strength shouldn't be like this. Look at yourself. Your legs are weak all the time, as if you're missing a kidney. When you fight an opponent, can you exert your full strength?"

Upon hearing Qingcheng's words, Kakashi looked embarrassed, but then said seriously, "I'll adapt as soon as possible. I'll definitely get used to this eye."

Qingcheng shook his head directly and said with a serious face, "You are not a member of the Uchiha Clan, so you cannot close the Sharingan. Therefore, you cannot adapt to this eye. However, there is another way to help you adapt to this eye as soon as possible and unleash its full potential."

Upon hearing this, Kakashi's face was filled with shock, and he said with a look of astonishment, "Really, Hokage -sama? What kind of method is that? What kind of price must be paid?"

Looking at the shocked Kakashi, Qingcheng said again, "It won't cost much. I happen to have a bottle on hand. Do you want to try it? After the Hokage, your body will be full of Chakra, and it will also enhance the power of your Sharingan."

Qingcheng then said with a serious expression, "Why don't you give it a try? This is the Enhancement Vaccine from my Uchiha Clan. Although it will hurt a bit, after you get used to it, I estimate that you will soon be able to break through to the Low-level Kage."

Kakashi was shocked upon hearing this, then embarrassed, and said, "Fifth Hokage, my money has already been used to buy 'Icha Icha Paradise,' and next month you're going to marry Kurenai, the month after that you're going to marry Yugao, and the month after that you're going to marry Meiling, Anko Mitarashi, Inuzuka Hana."

Kakashi sighed again, looking helpless, and said, "I really don't have any money to give as a wedding gift, but as the head of the Anbu, I can't exactly sit at that dog's table. If the Police Force notices me, it'll be too much trouble."

Upon hearing this, Qingcheng said with an embarrassed expression, "It's okay, Brother Xiao. I can lend it to you first. I won't charge you interest, and it won't be a case of 'nine out and thirteen back' (meaning it's not paid out). I'll deduct it from your salary when you get paid. This Uchiha Enhancement Vaccine is a personal sponsorship from me."

Upon hearing this, Kakashi's expression softened again, but he secretly thought to himself, "Thank goodness Lady Tsunade isn't planning on getting married, otherwise I'm afraid the entire Konoha Village would fall back into poverty."

Qingcheng gestured for Kakashi to come over and took out another vaccine. This first-generation Uchiha Vaccine contained more Chakra than the Second-Generation Vaccine, but its side effects were also more terrifying.

Qingcheng estimated that Kakashi's Sharingan should be able to withstand the backlash from Hashirama Cells, and could also replenish the power of his Mangekyō Sharingan. Kakashi wouldn't have to suffer from the Uchiha Clan anymore.

Kakashi also extended his right elbow, looking at Qingcheng's injection of vaccine, which seemed to contain a rich concentration of Chakra. Kakashi instantly guessed what it was.

Kakashi then asked awkwardly, "Fifth Hokage, is this thing really not dangerous?"

Qingcheng waved his hand and said, "Don't be afraid. I've experimented with this many times, and it's not the same as the First Hokage's Cells from Danzo and the others. Once you use it, you'll know how amazing the Chakra it contains is. It can even help strengthen your Sharingan."

Upon hearing this, Kakashi nodded again, his face full of gratitude, and said, "Fifth Hokage, thank you so much. I think I can hold on."

Qingcheng directly injected the Hashirama Vaccine into Kakashi's arm, and as the vaccine entered Kakashi's body...

Kakashi's face was also flushed red. A small growth had appeared where he had been injected. His Kakashi Sharingan seemed to sense a special power, instantly transforming into the Mangekyō Sharingan pattern.

Qingcheng also stretched out his hands and immediately activated the Mystical Palm Technique to help Kakashi quickly integrate the Hashirama Vaccine into his body.

Kakashi's eyes widened again as he stared at the Fifth Hokage's hands, which were radiating a huge green light. Kakashi exclaimed in astonishment, "Fifth Hokage, your mastery of Medical Ninjutsu is exactly the same as Lady Tsunade's!"
