Refining organs requires slaughter, and blood exchange also requires slaughter.

Lu Lianxiao's Tiger and Leopard Thunder Sound Technique is helpful for refining organs, but the amplification effect of blood exchange is not as good as before. He also thought that before the age of thirty, he did not want to waste too much time during the blood exchange stage.

"Blood exchange?"

Ran Haiqin said, glanced at Lu Lianxiao, feeling his breathing and heartbeat: "It seems that you have been working hard recently in your practice, and your internal organs are almost complete."

"It's still a little too late."

Lu Lianxiaodao.

Although he got a prescription for refining organs and his innate qi refining technique has also broken through to the second level, it is still a luxury to achieve refining organs in a few months.

He estimated that it would take at least half a year to keep medicinal materials.

"Since you ask about the secret of blood exchange, I will talk to you about the realm of blood exchange."

Ran Haiqin said, organizing a little bit of words: "If you want to talk about blood exchange, you must first mention the essence of the realm of blood exchange - blood. We humans belong to carbon-based life. Blood accounts for eight percent of the living body. It circulates the energy and organic matter of the human body to every corner of the human body, which is equivalent to gasoline in a car. Only better quality fuel can support a stronger engine..."

Ran Haiqin explained carefully, and Lu Lianxiao also listened patiently.

During this period, Ran Qingsi returned and saw this scene.

However, Ran Haiqin did not stop. After inviting Lu Lianxiao to have a meal, she continued to tell him the difference between the power of qi and blood condensed from the blood exchange realm and the power of martial arts.

It was not until he thoroughly told Lu Lianxiao that he stopped.

And at this time, it was already eleven o'clock in the evening.

Although Lu Lianxiao had other news to ask about, when the time came, he had to stand up and say goodbye.

"Qingshi is now in the blood exchange state. If you don't understand anything when you officially change your blood, you might as well ask her directly. You two are senior brothers and sisters, so you should help each other and don't have to be restricted."

Ran Hai's piano.

Ran Qingsi, who was beside him, nodded slightly.

"yes."
