As time entered the third year, January of Abyss Descent, rumors of Bloodline Demons began to surface in the Human World. These rumors weren’t about Bloodline Demons coming from the Abyss World, but rather about Bloodline individuals beginning to appear among humans. This timeline roughly matches Lu Heng’s memory. In the previous life, indeed, starting from the third year of Abyss Descent, Bloodline Humans began to appear gradually. The friction between ordinary humans and Bloodline Humans also began from this time and continued without cessation until the memory ended. In Lu Heng’s memory, the traits of the Bloodline Species are contagious. As long as there is a Bloodline presence, it will continuously spread. Just like most infectious diseases, it is very difficult to eradicate entirely. From an infectious characteristic, the simpler the transmission method, the faster the spread. ᴛʜɪs ᴄʜᴀᴘᴛᴇʀ ɪs ᴜᴘᴅᴀᴛᴇ ʙʏ novel_fіre.net The lower the mortality rate, the faster the spread. Infectious viruses have corroborated this point countless times; if the mortality rate is high, it triggers a strong human response. On the contrary, if the mortality rate is very low, it is usually disregarded as a minor illness. Becoming a Bloodline Human not only doesn’t result in death but also grants Strength, which provides extremely strong volition for its spread. About human Bloodlines, Lu Heng had already warned the nation more than a month ago. The remaining matters are beyond the scope of one individual’s Strength to manage. "Mr. Lu, the research report on the principles of expanding the scale of the Bloodline group has come out. Would you like to take a look?" This morning, Lu Heng received a call from Qi Jinhui. Regarding the dissemination method of Bloodline Humans, Lu Heng only knew the general idea and hadn’t seen the specific research report. Therefore, upon hearing Qi Jinhui say so, he asked him to send over the research report. The research on the Bloodline group belongs to confidential content but isn’t of a high security level. Qi Jinhui sent over the electronic file directly and advised against casual leakage. Of course, the confidentiality does not include other members of the team. Lu Heng was right in the Training Room at Qionghua Tianglu Lake and started reading the research report on the computer. As per this research report, the transmission method of the Bloodline Species is peculiar, a bit like viral transmission, but not entirely the same. The carrier of the Bloodline Species traits is a peculiar Energy Sequence, and this genetic sequence has a stable triple-helix structure. When the Bloodline Energy Sequence enters a biological body, it transcribes into a similar genetic sequence based on the biological genetic traits and embeds into the creature’s DNA. However, when it appears in humans, the Bloodline Species genetic sequence isn’t embedded in the chromosomal DNA but in the mitochondrial DNA. In human cells, mitochondria contain hereditary DNA material. Just that, the total amount is lesser compared to chromosomes. According to this research report’s analysis, the reason Bloodline genetic sequences implant into mitochondria is related to the energy factory traits of mitochondria. Mitochondria are the key organelles for humans to obtain Energy, whether it is the physical strength needed for ordinary people’s exercise or the Source Energy needed for Superpower Users to use Skills, both are produced by mitochondria. The Bloodline Species genetic sequences will adaptively adjust based on different biological energy organelles and inject genetic information into energy organelles. The energy organelles for humans are mitochondria, so the storage location for Bloodline Humans’ genetic information is mitochondria. After the injection of Bloodline’s genetic information, during reproduction, the egg cell contains this information, making the offspring also Bloodline. Moreover, among humans, whether male or female, the reproductive cells all have mitochondria. Hence, the Bloodline hereditary method does not differentiate between male and female; if either parent is Bloodline, the child born will have the Bloodline. After reading this section on the hereditary method of Bloodlines, Lu Heng felt chills down his spine. With this hereditary method, if not controlled, one day all humanity will become Bloodline Demons. At the end of the research report, the only consolation is that the initial Bloodline transformation process is not that easy. Because after the Bloodline’s genetic information is injected into mitochondria, it needs to spread across the body’s cells. The number of human cells is uncountable, and spreading to all body cells is not that easy. If intervention takes place at the initial transformation stage, there’s a chance to stop the transformation. Moreover, any foreign substance will be attacked by the human immune system. The immunity of ordinary people may not be enough to resist the transformation process, but the immune power of Superpower Users has a certain degree of resistance. Therefore, the initial Bloodline transformation requires a slightly longer conversion time, offering an opportunity for intervention under involuntary conditions. Scientists in Da Xia’s fields of biology and genetics have already begun researching the Bloodline transformation process, possibly finding a way to stop the transformation in the future. This research report clarifies the method of injection of Bloodline hereditary material, yet a crucial piece of information remains unanswered. That is the relationship between Bloodlines and the Abyss. From this research report, after Bloodline hereditary material is injected into the human body, humans will slowly transform into Bloodlines. Once transformed into Bloodline Humans, they not only do not die but also acquire Strength. If viewed solely from this point, it seems like a good thing. At least for individuals, obtaining Strength without any sacrifice, many would voluntarily transform. However, Bloodline Demons belong to the Abyss Race. Which means, after turning into Bloodlines, they would be summoned by the Abyss to attack other worlds being devoured by the Abyss.
