Establishing the Laboratory

Tonight was destined to be a sleepless night; Yu was very excited to have found solutions to two problems in one day.

However, implementing these solutions would be quite difficult, as neither was something that could be achieved overnight. It required a step-by-step approach. But with the adage "the beginning is the hardest part," once a goal was set, he could plan to tackle them one by one.

For the next period, Yu's days were very fulfilling. During the day, he went to the ninja academy with Sasuke, making plans during class. At noon, he would play with Naruto to "cultivate" their relationship. In the evenings, he trained with Sasuke at home, and before sleeping, he would spend two hours refining his Chakra.

His days were incredibly full.

In private, Yu had Yunshang Jinwei purchase various metals and experimental equipment. After several days of consideration, he decided to establish a private laboratory.

With the support of substantial financial resources, his laboratory's construction progressed rapidly. Furthermore, Konoha was also supportive of private laboratories.

In Konoha, many ninjas possessed unique ninjutsu, which required extensive experimentation to develop.

Developing ninjutsu was no simple task; otherwise, so many clans in Konoha wouldn't have achieved their current status through secret techniques. For example, the Akimichi clan's Expansion Jutsu, the Inuzuka clan's Beast Mimicry Ninjutsu, and the Yamanaka clan's Mind Transfer Jutsu... these were all incredibly powerful ninjutsu.

Therefore, Konoha was very supportive of personal laboratories and even had specialized teams of ninjas for constructing them.

Of course, conducting human experiments like Orochimaru was against regulations. However, Yu had no such intentions. While he was interested in the Art of Immortality, he didn't seem to need such a technique at the moment.

This was because Slimes had no lifespan limitations, unless they died from accidents or ran out of energy. Thus, he didn't need to worry too much about lifespan.

His laboratory was built ten meters underground in his yard, constructed by several ninjas skilled in Earth Style.

In civil engineering, ninjutsu seemed to be even more effective. The underground laboratory, spanning over two hundred square meters, was completed in just half an hour. Moreover, reinforced with Earth Style ninjutsu, its quality was comparable to that built with steel and concrete.

What he needed to do next was renovation and setting up the experimental equipment.

Sasuke was very supportive of Yu building a laboratory, giving Yu full control over the finances. Sasuke was incredibly wealthy now, and this amount of money was mere pocket change for him.

With a clear path forward in all aspects, Yu's laboratory was officially completed two months later. It could have been finished earlier, but some experimental instruments needed to be imported from other countries, causing significant delays.

Looking at his completed laboratory, Yu felt it was surreal. In his previous life, his highest academic achievement was a bachelor's degree in finance, and he was a liberal arts major.

He had fantasized about even transcending worlds, but he had never imagined owning a laboratory. The title of "scientist" didn't fit him at all.

Of course, this laboratory wouldn't be for professional research; it would only serve him.

Even so, it was not a simple task. He needed to learn, especially how to use the experimental equipment, which he had to learn from scratch.

An eight-year-old child conducting experimental research would be considered 99.99% fake news in his previous world. However, in the world of Naruto, such a thing was quite normal.

Summer turned to winter, signaling that the year was drawing to a close. Yu's presence in class had not increased during this time; rather, it had diminished further.

The book in Yu's hand made the other children in class feel even more that Yu was not one of them.

[Ten Theories on Kekkei Genkai]

This was the title of the book Yu held. To obtain it, he had even posted a C-rank mission at the Konoha mission office.

He could proudly say that after so many years, this was his favorite time to study.

Originally, such books were classified as forbidden, but now that things had slightly eased, they could be released, though they were still difficult to obtain.

Most of the information in this book was theoretical and had not been put into practice, but it deepened his understanding of Kekkei Genkai.

Although his target, Naruto, did not possess a Kekkei Genkai, he himself had one, as his identity as an Uchiha was not fake. However, he showed no signs of awakening the Sharingan, nor did the Uchiha physique manifest in him.

The Sharingan was the Uchiha's most powerful ability. Any Uchiha ninja with talent could awaken the Sharingan around the age of ten. If they couldn't awaken it during this period, they might never awaken it in their lifetime.

According to his memories, only his paternal grandfather had awakened the Sharingan among his direct relatives.

To maintain bloodline purity, the Uchiha clan mostly practiced intra-clan marriages. Of course, they would occasionally absorb talented foreign ninjas to harmonize the bloodline and prevent it from becoming polluted.

The world of Naruto also knew that consanguineous marriages could lead to genetic problems in offspring. The technological development in the Naruto world was quite good, even surpassing many aspects of his previous world by several times.

Yu naturally did not want to miss out on the Uchiha's power. Sharingan—Mangekyo Sharingan—Eternal Mangekyo Sharingan—Rinnegan, he desired them all. Therefore, finding a way to stimulate his own Uchiha bloodline was also a goal.

Upon returning home, he no longer trained with Sasuke. Instead, he threw himself into the laboratory. His laboratory hadn't started experiments yet; he needed to learn more knowledge.

However, there were already some tissues in a few culture dishes. These tissues came from three individuals: Naruto, Sasuke, and himself.

He had put in a great deal of effort to keep these tissues alive. If his current body wasn't a Slime, he might have gone bald by now.

However, during this process, he discovered something very strange: the tissues separated from his body grew exceptionally fast in the culture dish and began to develop towards the original form of a Slime.

About a month later, the tissues, originally the size of a fingernail, had grown to the size of a ping-pong ball, appearing as a transparent oval shape. This was the original form of a Slime.

Furthermore, this Slime had developed a certain consciousness. It might not be consciousness, but rather instinctive biological reactions. It would actively absorb food when encountered and actively avoid damage from flames, electric shocks, and other harmful stimuli.

This was practically more like a... than Yu himself.

"Slimes reproduce by splitting. Could this thing be my child?"

Yu thought of this somewhat chilling conclusion. He had never considered the possibility of having children, let alone giving birth to them himself.
