MTL - Your San Value is Zero - Chapter 439 Finally there is an heir?

In the land of the Xia Kingdom, every human being is born with what is known as a ‘resonance’, either to a specific element or a powerful, mythical beast. Unfortunately, Li Luo was born with an incredibly rare condition known as a blank resonance – as the name suggests, he doesn’t have one! Normally, this would be utterly crippling, but at least he has the advantage of being the young master of the mighty House Loulan, one of the five Great Houses of Xia. Unfortunately, his parents, the powerful masters of House Loulan, have gone missing for many years, and the other Great Houses are beginning to eye their holdings quite hungrily. For that matter, plenty are also eyeing his talented, beautiful childhood friend and fiancee Jiang Qing’e, who has been leading House Loulan in his parents’ stead! Li Luo would much rather keep a low profile and wants to call off the engagement – but Jiang Qing’e has flatly refused. What’s a ‘useless young master’ to do?

The chief female forensic investigator, Ran Yan was secretly killed by her assistant. Unexpectedly, she was reborn in the years of the Tang dynasty. After experiencing a narrow escape, she fled from Jiangnan to Chang’an. Although, Chang’an was at the beginning of its flourishing period under the Li family’s Tang dynasty, various princes were vying for the throne by using all kinds of strategies. This was the dark days of the imperial court, where one needed to walk on a tightrope as one’s life was as powerless as an ant. The Xiao family controlled a large amount of wealth so inevitably they also became involved in the conflicts.

After arriving in Chang’an, she discovered many suspicious incidents: the original owner had unexplainable amnesia but his family was indifferent. She once again saw the orchid shaped clay inkstone, a valuable object that her mother has given her in modern times. Hence, could it be that she can time travel back? In order to survive in the Tang dynasty, she displayed her strong spirit and willpower by learning medicine from a doctor, pretended that she benefited from being sick on how to cure diseases, suffered hardship in earning money, manufactured penicillin, cured syphilis, and used her autopsy skill and experience to solve each and every murder mysteries.
