Simultaneous Transmigration: Starting from the Main God Space

"The funding issue can be resolved for now."

Upon hearing this, Wu Xian took out a document resembling a bankbook from his pocket. This was a universal bank note certified by the Daimyo of the Land of Fire, which could be exchanged for a huge sum of cash at the money shops of various ninja villages.

"The Uchiha clan was extremely generous in expressing their gratitude."

This gratitude stems from Wu Xian's positive role in easing tensions between the Uchiha clan and the village, as well as in encouraging Uchiha Itachi and other clan members to join the Anbu system.

In Konoha's political landscape, it is an unspoken tradition for powerful ninja clans to "gift" those who have rendered them service to them. This practice is not even considered bribery, but rather a symbol of status and influence.

Even the Fourth Hokage, Minato Namikaze, upon learning of this, could only make a lighthearted comment about Wu Xian's luxurious property in the center of the village—a property personally arranged by Fugaku Uchiha, worth tens of millions of ryo.

The amount represented by the note in Wu Xian's hand was as high as 100 million taels, which was enough to support his research plan to enter a new stage.

Upon entering the base, Wu Xian went directly to the core laboratory.

He took out the scroll he had obtained from Orochimaru's legacy and immersed himself in it once again.

These scrolls record Orochimaru's life's work in the field of life sciences, especially the information on "directed cell culture," "somatic cell cloning technology," and "gene sequence stability and expression," which are the treasures that Wu Xian urgently needs right now.

His gaze swept across the complex formulas and diagrams, his brain working at lightning speed. Combining his own theoretical knowledge that was ahead of its time, he constantly verified, deduced, and even began to correct and improve some flaws and limitations in Orochimaru's technical system.

It can be said that, in terms of pure bioengineering theory, Wu Xian has already stood on Orochimaru's shoulders and seen a more distant view.

While sorting through Orochimaru's inventory samples, a cell culture jar labeled "Kaguya Kimimaro" caught Wu Xian's attention.

"The Kaguya clan's Shikotsumyaku... Did Orochimaru collect this to research a way to cure their bloodline disease?"

Wu Xian seemed to be deep in thought.

The bloodline limit of the Kaguya clan and the Byakugan of the Hyuga clan can both be traced back to the younger brother of the Sage of Six Paths, Hamura Otsutsuki.

A bold and highly enticing idea quickly took shape in his mind.

"Hyuga Neji's Byakugan cells originated from the descendants of Otsutsuki Hamura. Kaguya Kimimaro's Shikotsumyaku cells were also inherited from the Kaguya clan, and their origins can be traced back to Hamura's power system."

His gaze suddenly sharpened and became focused, as if he had pierced through the thick glass of the culture tank and seen the possibility that existed at the theoretical limit.

"They share the same origin, yet have taken on completely different forms of expression... just like different segments on the same gene sequence that are silenced or activated due to epigenetic modifications or mutations at key nodes."

"Since they are homologous, there must be some degree of compatibility and complementarity at the underlying gene sequence level. If these two cells, which contain homologous but different phenotypes, are forcibly fused, induced, and cultivated... under extremely precise regulation, it might be possible to break through the expression limitations caused by bloodline dilution or mutation in later generations, and make up for the defects in their respective gene chains... Theoretically, there is an extremely low probability that cells could undergo 'reverse evolution' towards a more ancient and primitive form, that is—'atavism'!"

What is the ultimate goal of atavism?

It is a power form that is closer to that of the progenitor, Hamura Otsutsuki!

Even the legendary Tenseigan, which is said to be the ultimate form of the Byakugan, on par with the Rinnegan of the Sage of Six Paths, and is considered the supreme eye technique with the power to create and destroy the world!

Once this thought arose, it burned fiercely in his heart like the most intense flame.

Risk? Extremely high.

Ethics? In the pursuit of truth and power, this has never been the primary consideration.

Success rate? Extremely low.

But for a researcher, even a one in a billion chance is worth the effort to try.

Without the slightest hesitation, Wu Xian began his operation.

He seemed like a sophisticated machine that had been instantly activated, and walked to a more advanced, multi-functional sterile workbench next to him.

He first put on specially made micromanipulation gloves and connected them to a high-precision hydraulic feedback system.

Inside the control panel, the robotic arm, under his mental control, operated with precision, like an extension of his limbs.

Step 1: Sample pretreatment and cell line establishment.

He skillfully retrieved the well-preserved "Hyuga Neji (White-eye variant) active cornea and optic nerve cells" sample.

The robotic arm uses a laser micro-dissection tool to separate an extremely small piece from the edge of the tissue and place it in a culture dish with a special enzymatic solution added.

Under constant temperature control, the enzymatic hydrolysate gently digests the connections between cells, ultimately yielding suspended, highly active individual sclera cells.

These cells were rapidly transferred to a specially formulated "neural crest cell directed culture medium" rich in neurotrophic factors and specific epigenetic modifiers, designed to maintain and amplify the pupillary potential in sclera cells while inhibiting their tendency to differentiate into ordinary somatic cells.

Next, he processed the sample of "Kaguya Kimimaro".

He specifically selected the bone marrow stem cells next to those few pieces of active bone fragments.

These stem cells have greater plasticity and proliferative capacity. They are placed in a different "high-intensity osteoblast/chondrocyte induction culture medium," which aims to moderately activate their underlying, more ancient gene expression programs while maintaining their "cadaveric" characteristics.

Step 2: Constructing the fusion carrier and introducing the "fusion agent".

Simple cell mixing will only lead to rejection or death.

Wu Xian needs an "adhesive" and a "controller".

At this point, he took out his own cell sample.

He processed some of his own somatic cells (mainly fibroblasts with strong metabolic and fusion capabilities), extracted specific proteins and signaling molecules from their cell membrane surfaces, and prepared them into a "fusion promoter".

Meanwhile, he plans to use modified cytoplasm, which has had most of its genetic information removed but retains its own cytoplasm, as the "recipient cytoplasm" in subsequent nuclear transplantation steps, which can greatly improve the compatibility of xenogeneic cell nuclei.

"Although the nuclear genetic material of the cloned clones comes from the target, their cellular environment and epigenetic imprints will be deeply marked by me. This means that at the fundamental level, these clones are 'of the same origin' as me. When they are finally fused through the Ghost Sprout Technique in the future, the rejection reaction will be minimized, and they will be able to perfectly inherit my will, avoiding the backlash that happened to Hiruko."
