"It''s a little difficult to understand the mysterious eight tones with the scientific level of the Xuanyuan continent, but it''s easy for me to understand."

    Su Chen whispered, "everything is made up of atoms. Atoms can vibrate. Even the hardest and stable iron block is constantly making small vibrations when observed at the extreme micro level. Since it will vibrate, there will be sound."

    Everything has spirit and everything has sound. There is no absolute silence in this world. Where people can''t hear, everything is making its own unique sound.

    If you can hear these sounds, you can catch any slight movement of things around you.

    This mysterious eight tone is to enhance your hearing to the extreme and listen to the sound of the surrounding environment. Even the weakest infrasound wave can be heard clearly.

    However, practicing Xuan listening to eight tones also has a disadvantage, that is, too many voices can be heard, which will become difficult to distinguish.

    However, the person who created this set of skill has also considered this problem, so it is Xuan listening to eight tones, rather than listening to one voice.

    These eight tones are not the eight tones of the eight tone box, but the sounds of various substances.

    The sound of soil, the sound of vegetation, the sound of air... And the sound of human body.

    These voices can be heard alone.

    The most useful thing for practitioners is naturally to listen to the voice of the human body.

    After all, the human body is a living thing. The blood in the body keeps flowing, and the sound will be more unique and obvious. It is the most easily heard sound.

    By listening to the human voice, anyone can find out in advance as long as he is close to Su Chen, no matter how well the other party hides.

    Moreover, different voices also contain different information. By judging each other''s heartbeat speed and breathing rhythm, you can even roughly guess each other''s intention and purpose. If you come with killing intention, the voice sounds more obvious.

    "Good skills, point full."

    There are thirty layers of xuanting Bayin. Each layer needs five skill points. Su Chen is full of them.

    In an instant, the whole world in Su Chen''s ears seemed to be completely different.

    With your eyes closed, you can clearly distinguish the detailed environment around you through the sound from all things.

    However, there were too many and too noisy sounds. Su Chen turned off other sounds and only listened to the sounds emitted by the human body.

    He heard that Huang Zhan sat quietly waiting outside the door. He breathed evenly and his pulse was steady, like a statue.

    Outside the Sutra Pavilion, the guards were whispering and discussing the gossip about Su Chen.

    Their conversation was heard clearly by Su Chen, as if whispering in his ear.

    In addition, Su Chen heard another voice.

    "Chu Yanran? What is she doing furtively?" Su Chen frowned and went to the window to look down. Sure enough, she found that Chu Yanran was really pacing outside the Sutra Pavilion. Her heart beat very fast and her breath was very confused. She didn''t know what she was thinking.

    Hasn''t she given up trying to assassinate herself?

    Su Chen''s mind moved and went outside the door to give Huang Zhan two orders.

    Huang Zhan immediately nodded and jumped out of the window with a flash of his body. Less than two breaths, he flew back with Chu Yanran.

    "Let go of me!"

    Chu Yanran struggled, but she was just the strength of xuanjing. In front of Tianjing experts such as Huang Zhan, she had no resistance at all.

    Su Chen looked at Chu Yanran with a smile: "Chu Yanran, aren''t you locked up? How did you escape alone?"

    Chu Yan angrily stared at Su Chen: "Cheap slave, how dare you call the name of this palace."

    "Pa!"

    Su Chen''s backhand is a big ear scraper. He pulls Chu Yanran''s face and directly dazes Chu Yanran. He looks unbelievably stunned. He can''t believe that Su Chen dares to hit himself.

    "Damn it! Cheap slave! You''re dead. Even if you become a national teacher, you''re just a Cheap slave of the Chu family. I''ll let my father break you into pieces and feed you to the dog!" Chu Yanran said fiercely.

    "Bang!"

    Su Chen was more straightforward this time. She clenched her fist directly and hit Chu Yanran''s lower abdomen hard.

    Chu Yanran fell to the ground with a bow and a cold sweat, but she didn''t admit defeat. She cursed Su Chen and said anything vicious.

    Su Chen snorted coldly and said, "Huang Zhan, bring her to me to the Danqing hall and lock her in the water prison. I want to see how long she can be tough."

    Huang Zhan hesitated and said, "master, this is wrong. After all, this little girl is a princess."

    "What about the princess? Tell Chu Tianming that I want to punish Chu Yanran instead of him. If he is distressed, let him come to the door and pull people. At that time, I can return Chu Yanran to him, but I don''t care to be a national teacher. Let him measure it by himself."

    Su Chen now has a big fist and has a lot of hardness in his speech. What about the emperor of the state of Chu? Why should he sell his face.

    "This... Disciple obeys." Huang Zhan was helpless, but he did it according to Su Chen''s words. After all, he is now Su Chen''s disciple and has to face his master in everything.

    Moreover, Huang Zhan knew how terrible the value of a medicine refining master was. Chu Tianming would never easily offend Su Chen.

    After returning to the Danqing hall, the news that Su Chen detained the nine princesses soon spread to Chu Tianming''s ears.

    Chu Tianming was also shocked. He just wanted to go to the Danqing hall to plead for mercy in person, but at this time, a beautiful woman dressed in luxurious palace clothes came over.

    "Your Majesty, you''d better let me go. Master Su is young and energetic. After suffering so much in Yanran''s hand, he will certainly not give up. If you go to him now, you may completely annoy master su. As Yanran''s biological mother, it''s more appropriate for me to plead."

    While the beautiful woman was talking, the three furry fox tails behind her swayed from side to side.

    "Well, it''s more appropriate for you to come forward by Princess Hu, but you must remember that you must not offend master su. If you go here, whether you can save Yan Ran is the second. The first task is to calm master Su''s anger. When necessary, you can use all your skills and never let master Su step down as a national teacher."

    "... I take orders."

    When she turned around, a trace of slight and undetectable disappointment flashed in her eyes.

    Danqing hall.

    Su Chen is sitting on his knees in a pavilion in the back garden, soaking up the energy of heaven and earth.

    What he is practicing now is a mysterious level skill "Na Yuan breath breathing skill", which belongs to the basic cultivation skill like Xuan Yuan skill, but it is more powerful than Xuan Yuan skill. He can directly absorb the vitality of heaven and earth into his body through breathing and breath to enhance his cultivation, which is several times higher than the cultivation efficiency of Xuan Yuan skill.

    In the past, Su Chen was not qualified and could only practice the Xuanyuan skill of the yuan level, but now without the qualification limit, he can naturally choose a better skill to practice.

    But just step-by-step practice, efficiency is still not enough.

    So he also made himself a heaven level pill ''powerful cultivation pill''.

    One pill can increase Su Chen''s cultivation speed a hundred times in five hours!
