Seeing a battle spirit act in such a serious manner, Ling Yan's expression became much more serious, and he waited for the battle spirit to speak.

This time, the battle spirit wasn't mischievous and directly said, "Little master, I'll explain why you want to absorb the blood essence first. Otherwise, you won't even be able to sleep soundly if you think about it every day."

Disregarding Ling Yan's somewhat embarrassed expression, the battle spirit stroked its own somewhat illusory and elegant long hair as it continued to speak.

"Little master, I heard from him that because of the explosion of the previous master, his cultivation level dropped from a top six star to a one star. 32 times the battle strength has increased, and that's more than double the battle power, right?"

Ling Yan nodded his head to show that he remembered.

"That's right. Do you know why you were able to enter someone's battle spirit space in the beginning? Forget it, I won't ask you anymore. Even if I ask you, you won't know …"

"I don't know. Why don't you tell me then?" The corners of Ling Yan's eyes slightly twitched.

The battle spirit seemed to have ignored Ling Yan's somewhat darkened expression. It twisted its waist and said, "Because at that time, I felt a trace of the blood essence and then absorbed it. Little master, you were then able to enter this person's battle spirit space.

Ling Yan wasn't stupid to begin with. As he heard his battle spirit speak to here, a light lit up in his mind. Without waiting for his battle spirit to speak again, Ling Yan spoke.

"So what you're saying is that you actually need blood essence to raise your cultivation level?"

"Yes, and no."

The battle spirit giggled. Her slender jade hands tapped Ling Yan's forehead as she praised, "Little master's mind is still quite bright. But if I want to recover to my peak condition, I have several ways."

"Firstly, through the radiation effect of the energy in the body of the current master, I will slowly treat his injuries. This is also why he told you to quickly raise your cultivation level, because the higher the cultivation level of a martial artist, the more intense the radiation is …"

The second reason is to use someone else's body to protect themselves from falling into a deep slumber, and then absorb the energy of heaven and earth to recover by themselves. This is also why that person often falls into deep sleep, and little master's current strength is not enough for someone to remain awake for a long time.

As for the third reason, that is because they had done something just now, and that is because they needed the blood essence of a martial artist to be nourished. The blood essence of a martial artist contains the purest of their energy, and the nourishing effect is also very good; the higher the cultivation, the more talented a martial artist is, the more pure and powerful their blood essence would be, and the better the effect would be. "

As the battle spirit spoke, Ling Yan was puzzled.

"But I remember that after I killed the guard named Ouyang Chao last time, you didn't appear to absorb his blood essence …"

"Humph, that guard is just a piece of trash, the blood essence in his body is not pure at all. If this kind of blood essence is absorbed, wouldn't that be staining his body? Only a mortal at the fourth level of the Mortal Stage is barely strong, of course, it would be best if the little master is a genius like this right now …"

As the battle spirit spoke, it extended its small red tongue towards Ling Yan and licked its bright red lips.

Uh, Ling Yan hurriedly took a few steps back, reminding him, "Don't hit me. I'll tell you, or else I'll …"

"Isn't that all? Little master, do you want to hit me? Wa, wa, I'm really scared …"

The battle spirit pretended to be afraid. Then, it pouted its small, rosy lips and caved in. Her curvaceous body shot out a coquettish glance. "Little master, come here and let you hit me, hit this place …"

Ling Yan was exasperated. Was this a person who had lived for tens of thousands or even hundreds of thousands of years? How could he be so mischievous?

However, after having his battle spirit interrupted, Ling Yan understood that in order for a battle spirit to absorb blood essence and raise its boundary, what was needed was the blood essence of geniuses. This was because the energy within a genius martial artist's body was far more pure and formidable than that of an ordinary martial artist.

So it was like that.
