Su Chen and Xie Xuanji talked happily all the way, and soon came to the deepest part of the secret realm of yin and Yang. On a chaotic wall, a black-and-white door appeared.


    "Elder martial brother Xie, can I open this gate by inputting pure Yin and pure Yang into it?"


    "That''s right." Xie Xuanji said, "to integrate the power of pure Yin and pure Yang together and inject them into each other one by one, one by four, this is the most difficult place to open the door. Even if I find a pure Yang body and a pure Yin body at the same time and let them inject power into the door at the same time, it will still form a situation where Yin and yang are difficult to integrate and can''t open the door."


    The requirements are really strict. It seems that there are many good things behind the gate.


    Su Chen stepped forward and, without saying a word, combined the power of pure Yin and pure yang to form a blue flame, which blew out directly towards the door.


    The blue flame did not explode, but was absorbed directly by the gate.


    The power of the flame that can flatten the mountain can be imagined, but after entering the gate, it is like a stone sinking into the sea without causing any fluctuations.


    "Not enough."


    Xie Xuanji said.


    Su Chen took a deep breath and gathered a blue flame again.


    Finally, the gate reacted and burst into a faint black-and-white light.


    But still not enough.


    Su Chen puffed up five blue flames.


    "Bang!"


    After absorbing enough energy, the gate finally opened.


    A dazzling golden light came straight from the gate.


    Xie Xuanji didn''t have too many surprised expressions. In his current status, he couldn''t raise much interest in what was hidden behind the door. Opening the door was just a long cherished wish for him.


    Since its development, Zhongmiao gate has become one of the four top religious gates in Xuanyuan and Yuan Dynasties. Even without the treasure behind this gate, it can still remain strong.


    "Younger martial brother Su Chen, please."


    Xie Xuanji didn''t use Su Chen to let him leave, but invited him to enter the gate together.


    Su Chen was also very curious about the world behind the gate. She angrily accepted Xie Xuanji''s invitation and walked in side by side with Jin mang.


    Across the gate, the golden awn dissipated in an instant.


    Su Chen looked around and saw that there was a huge square space, about 500 meters long, wide and high. It was a standard cube, surrounded by not walls, but a barrier composed of light.


    An ancient vitality came to my face.


    Su Chen couldn''t help taking a deep breath. The vitality was very strong. Su Chen breathed faster and immediately felt his head drifting.


    "A little above..."


    Su Chen quickly held her breath.


    You can''t suck more energy, or you''ll get drunk.


    It had no effect on Xie Xuanji. He strolled into the cube space composed of this barrier, glanced and was a little confused.


    "No, why don''t you have anything?"


    Although Xie Xuanji doesn''t care what''s hidden here, it''s the treasure left by the first generation sect leader. There should be something right. The first generation sect leader won''t be bored enough to set such a difficult way to open the door, but only leave an empty room?


    Su Chen observed carefully for a long time and found nothing: "elder martial brother, can these ancient vitality be the treasure left by your early sect leader?"


    Xie Xuanji shook his head: "although the vitality here is of high quality, it is only vitality after all. It is not a treasure. There must be other existence here, but we are mortal and can''t find it."


    Su Chen frowned, and the identification technique swept around, but there was still no discovery.


    At this time, Xie Xuanji seemed to notice something. A strong fine light burst out in his eyes, as if he could penetrate the space until the most original existence in the space.


    In an instant, the red awn flashed, revealing the outline of a flying sword in the square space.


    The flying sword only showed a faint shadow, which brought an extremely terrible feeling to Su Chen. He was soaked with sweat for a moment, and subconsciously stepped back for several steps.


    Xie Xuanji suddenly looked shocked.


    "I see. It''s it!"


    "What did elder martial brother find?"


    Xie Xuanji raised his hand. The red flying sword leaped from the void and fell directly into Xie Xuanji''s hand.


    The whole body of flying sword emits dark red light. Unlike ordinary flying sword magic weapons, it even has no entity. It is completely between virtual and real existence.


    Xie Xuanji looked at the red flying sword in his hand. He looked very dignified. He seemed to have some doubts. He seemed surprised why the red flying sword appeared here.


    He must know the origin of the flying sword.


    However, Xie Xuanji didn''t say, and Su Chen was embarrassed to ask. After all, his task was just to open the door. No matter how powerful the flying sword was, it belonged to all the wonderful doors, and he certainly had no right to intervene.


    Xie Xuanji was silent for a long time. He suddenly sighed and sent the red flying sword back to its original place. He took Su Chen away from the secret realm of yin and Yang.


    Along the way, Xie Xuanji frowned and said nothing. He didn''t know what he was thinking.


    Unconsciously, they have returned to the monastery.


    Fairy Bixia is still waiting here.


    Xie Xuanji only recovered at this time. He handed a heaven and earth bag to Su Chen: "younger martial brother, take care of it. Don''t say anything about today. Otherwise, I''m afraid it will bring disaster to our wonderful doors."


    Su Chen solemnly nodded. It seems that the red flying sword has a great origin. Just divulging the news will bring disaster to all wonderful doors. This is by no means an ordinary flying sword. It can''t even compare with artifact. After all, there are few artifact in any big sect. Artifact is nothing for these giants.


    Su Chen opened the heaven and earth bag and took a look. It was full of 100 million yuan cores.


    Heavy and joyful.


    Su Chen said, "elder martial brother, farewell."


    Xie Xuanji regained his former benevolent look and said, "I''m going to attend the ascending Dharma meeting. I hope the younger martial brother can get a good result. Elder martial brother has nothing to give you, so I''ll give you a word."


    Then Xie Xuanji grabbed Su Chen''s palm and wrote the word "Sheng" in his palm.


    What a powerful power of divine pattern!


    This is the method of carving divine patterns on the flesh. Although Su Chen can also use them, he is definitely far inferior to Xie Xuanji. He must be the top talisman!


    Feeling the majestic vitality contained in this character, Su Chen knew that this was the means to protect his life given by Xie Xuanji.


    Su Chen felt warm and bowed down and said, "thank you, senior brother Xuanji."


    "Go."


    Su Chen nodded, turned around and flew away with Bixia fairy by Hongqiao.


    Leaving the core of Zhongmiao gate, Su Chen found that Bixia fairy was looking at Su Chen with a surprised look and asked, "do I have flowers on my face?"


    "Why did the sect leader call you younger martial brother." the storm has already turned up in Bixia fairy''s heart. Just now it''s hard to ask, and now she can''t help it.


    "Ha... You heard me wrong. How can I be the younger martial brother of the sect leader?" Su Chen smiled foolishly, and then sped away.
