Reincarnation as Lower Rank Five in Demon Slayer

Chapter 164 Research on the Demon-Eating Physique (3)

"Haha, just kidding, just trying to scare you, I won't prick you with this syringe."

Li Lei laughed and tossed aside the large syringe, which was as thick as his arm, and took out a normal-sized syringe from his pocket, waving it in front of Xuan Mi.

"Look, this is the syringe I need. It doesn't look so scary anymore."

Seeing the normal-sized syringe that Li Lei had taken out again, Xuan Mi breathed a sigh of relief. The syringe from before had almost scared him to death. Fortunately, the adult in front of him was just joking.

Otherwise, if he saw a needle as thick as a chopstick piercing his body, he would either be killed by the needle or scared to death.

Next, the experiment began. Li Lei first went to Xuan Mi's side and used the syringe in his hand to draw a vial of Xuan Mi's blood for the first experiment.

Li Lei took the blood from the syringe and went to the test tube containing the flesh and blood of various ghosts. He dripped Xuan Mi's blood into each test tube in turn to see what would happen.

As Li Lei dripped the remaining blood of Genya from the syringe into Muzan's blood, the blood of Genya, which had initially been mixed with ordinary demon blood and flesh, underwent a noticeable change. The blood and flesh of the ordinary demons had been almost completely devoured by Genya's blood.

"Heh, it seems that the flesh and blood of ordinary ghosts are no match for Genya's blood."

Li Lei watched with amusement as the changes occurred in the test tube in front of him. Soon, the blood and flesh of the demon with the Blood Demon Art were also devoured and assimilated by Genya's blood. Finally, when it came to Muzan's blood, Genya's blood was directly devoured by Muzan's blood.

"Sigh, it seems that Genya will turn into a demon if he eats Muzan's blood directly without activating his Demon Eater physique."

The situation in these test tubes was similar to Li Lei's expectations; Muzan's blood K was indeed not something Genya could handle head-on.

Looking at the experimentally prepared flesh and blood in the test tube in front of him, Li Lei stared intently at Muzan's blood, and a question immediately came to his mind.

Could it be that Genya's blood was too scarce, causing him to be devoured by Muzan's blood? If I added more of Genya's blood or flesh, would the situation change in any way?

Thinking of all this, Li Lei immediately took action, drawing a full syringe of blood from Xuan Mi for experiments. He even took a small piece of flesh from Xuan Mi's arm and added it to the Muzan blood experiment, of course, under anesthesia.

A few minutes later, the test tubes containing Genya's blood and flesh chunks of Muzan's blood were placed in the test tubes again. The results were the same: Genya's blood and the small flesh chunks were all consumed and infected by Muzan's blood, turning into demon blood and demon flesh.

"Is it not possible? Directly using Muzan's blood is still too difficult for Genya."

Seeing how easily Muzan's blood infected Genya's flesh and blood, Li Lei was not happy with the result. Although it was expected and reasonable, Li Lei still refused to believe that adding so much of Genya's blood and a small piece of flesh would not cause any change.

"Wait, there must be something he didn't notice. As someone with the Demon-Eating Physique, Genya shouldn't be powerless to resist even a drop of Muzan's blood."

What is it that he hasn't thought of yet? Right, Xuanmi hasn't truly activated his Ghost Devourer physique yet. He should have to eat the flesh and blood of ordinary ghosts to activate his Ghost Devourer physique.

Thinking of all this, Li Lei immediately wanted to conduct the experiment. However, considering that people with the Ghost Eater physique are even rarer than those with the Rare Blood physique, Li Lei did not want to let Xuan Mi eat ghosts and activate the Ghost Eater physique so quickly.

He didn't even fully understand Xuanmi's physical condition when he was human. If he were to activate Xuanmi's Demon Eater physique now, he would lose a lot of useful experimental data.

However, if Li Lei doesn't activate the Demon Eater physique for Genya, he won't know the effect of activating the Demon Eater physique on Muzan's blood.

"Ugh, this is such a difficult choice."

Li Lei looked worried, unsure whether to feed Xuan Mi ghost meat right now.

Just as Li Lei was struggling with this problem, he accidentally saw the test tubes on the table, and a sudden inspiration flashed in his mind. Li Lei thought of a solution.

Since he doesn't want to feed Genya demon flesh and activate his Demon-Eating Body yet, he could try a different approach. He could use a small piece of Genya's flesh to absorb demon flesh and blood, turning that piece of Genya's flesh into the flesh and blood of the Demon-Eating Body, and then add it to Muzan's blood experiment.

Li Lei thought to himself that the experimental effect should be similar to that of using Xuanmi to activate the Ghost Eater physique. Both are Ghost Eater flesh and blood, except that one turns the flesh into Ghost Eater flesh and blood, and the other is taken from Xuanmi to become a Ghost Eater physique.

The experimental results should all be the same. With that in mind, Li Lei immediately began the experiment.
