Chapter 1421: Chapter 1066: Undercurrents Stirring Chapter 1421: Chapter 1066: Undercurrents Stirring Sisi’s recovery is swift, as long as the metastatic tumor inside her skull can be reduced below the critical threshold, without causing significant suppression of myocardial pulsation, there won’t be any immediate threat to her life.

Of course, there are other dangers, like tumor hemorrhaging, but should these arise, they can at least be addressed with surgery, such as emergency operations to remove hematomas if intracranial hemorrhage causes compression. Surgery is Yang Ping’s forte; in his hands, any problem that can be solved with surgery isn’t considered a problem.

Therefore, Yang Ping is not immediately worried about Sisi; rather, he himself is somewhat concerned as the virus still hasn’t been cleared from his body. Although there are no special adverse reactions, it remains a latent threat.

He has his own blood drawn for viral titer monitoring. The report from Nandu Medical University’s virus laboratory shows that the K virus is still present but at a lower titer than before, indicating that the viral load is still decreasing.

As there are currently no adverse reactions and the viral numbers are falling, he decides to have regular check-ups. Yang Ping is not anxious about this for now. Truly clearing the virus from the body would require the development of a drug targeting the K virus, a formidable task that he doesn’t have the luxury to focus on at the moment.

The virus Yang Ping injects into Shishi has been modified to knock out the replication gene. Once these viruses are introduced into the body, they are incapable of replication, effectively fighting a two-front war against tumor cells and the immune system–they die off one by one. The replenishment of their fighting force relies on subsequent injections of the K virus. However, there remains an issue with reinjections of the K virus–it has to travel from the injection site to the tumor, and during this process, it undergoes attacks from the immune system.

Yang Ping wonders, could he not knock out the replication gene of these viruses? Allowing them to replicate within the body could mean that after braving the immune system on their way to the tumors, even if only a few viruses survive, they could parasitize inside the tumors and, relying on the tumor cells for replication, quickly build up numbers sufficient for widespread infection and eradication of the tumors.

Of course, this approach carries a huge risk; if the viral replication becomes uncontrolled, could it lead to uncontrollable severe consequences? Could it potentially cause a new disease? After analysis, Yang Ping concludes that this possibility is very low, and so far, the virus staying within his body has not caused any other diseases.

No matter how the K virus mutates, it cannot escape the constraints of the source virus. Like the influenza virus, even if they mutate, they only cause influenza with varying symptoms.

The source virus used for the K virus is quite safe, so no matter how it mutates, it cannot change its basic structure. Structure dictates properties, so its fundamental characteristics will not change much. This is the theoretical basis for Yang Ping daring to experiment with live viruses.

In fact, although the K virus is derived from another virus, it can no longer be categorized as a virus. Yang Ping believes it should be called an activatable tumor cell apoptosis protein complex.

This is a bold notion; when Yang Ping shared this daring idea with Lu Xiaolu and Professor Zhang Zhiwei, they were both very surprised and thought it was a bold concept. Were they to conduct this experiment themselves, they would certainly not dare to contemplate such a thought.

Because all current medical applications that employ viruses for prevention or treatment require that the viruses be castrated, knocking out the replication gene to prevent a self-replicating virus from going rogue and causing serious consequences.

For example, oncolytic virus therapy follows this rationale, as do certain vaccines, and all other medical measures involving viruses do not deviate from this approach.

Professor Zhang Zhiwei simply cannot agree with this bold idea, while Lu Xiaolu believes it’s possible to try within a limited scope; he supports Yang Ping in realizing this new concept.

When Fujiwara Miyuki received the task from her brother, Fujiwara Wakan, she emphatically refused; she would not do anything to harm Yang Ping.

When Fujiwara Wakan assured her that there would be no harm done to Yang Ping, merely an invitation to recruit him, and that if he could become part of the Fujiwara Family, it would be a blessing for the entire clan. Furthermore, Fujiwara Wakan told Miyuki that if she liked Yang Ping, why not pursue him, why not strive for her own happiness.

This statement touched Miyuki’s heart. Indeed, why shouldn’t she pursue this? If she tried and still failed, she would have no regrets in her life.

The few months she spent as a visiting doctor at Sanbo Hospital left her with many beautiful memories. That experience is unforgettable for her and comprises some of her life’s most cherished recollections.

Now that Yang Ping is a husband and father, but Miyuki still can’t forget him, she feels she never will in this lifetime. Apart from this man who stands at the mountain’s peak, there is no room for any other man in her heart.

After some deliberation, Miyuki decides to accept the task, whether for herself or for the family, she is willing to try.

Most of Japan’s major trading companies have their own intelligence networks, such as the renowned Mitsubishi Corporation, which has its network spread across the world–a Japanese business tradition.

As a vast family enterprise like the Fujiwara Family, they certainly also have their intelligence network distributed globally. They collect various pieces of intelligence to support their strategic decisions.
