Gu Yulian''s jade ball, which was divided into two parts, was obviously the key to the arsenal of the blood god palace.


    After turning the key, a round bronze plate was unscrewed in the middle of the bronze heavy door, revealing the golden wheel inside.


    The golden Roulette has a diameter of one foot and is engraved with the figures of the twelve zodiac signs of heavenly stems and earthly branches around it.


    More importantly, with the emergence of the golden wheel, the surrounding ground is also roaring and shaking. On the mountain wall and dome, stone slabs move away automatically, revealing deep holes.


    "What mechanism is this?" Bai Xiaowen glanced around cautiously.


    Gu Yulian glanced at Bai Xiaowen and said, "behind the door is the largest secret place of the blood god palace. There is no guard. Of course, we should set up powerful mechanisms. The jade ball in my hand can only let us see this twelve yuan gold plate. Next, we have to move the disc finger needle seven times in the correct order to open the door of the arsenal."


    After a pause, Gu Yulian said again: "in these seven rotations, the disk pointer should be turned to the correct Yuanchen image every time. Even if there is an error, the Arsenal mechanism will be triggered immediately."


    Although Gu Yulian didn''t say what it would look like after the Arsenal mechanism was triggered, looking at the dark holes around, Bai Xiaowen felt a thrill.


    This gold disk is equivalent to a 12-digit, 7-digit password box. There are more than 30 million possible combinations, but only one is correct. The wisdom of ancient Chinese craftsmen can never be underestimated.


    "Young master Bai, please step aside. I''m not used to people standing too close to me." Gu Yulian said.


    Knowing that she was protecting the secret of the disc pointer, Bai Xiaowen walked aside. However, he remembered Gu Yulian''s movements every time he moved his fingers.


    Bai Xiaowen recorded the range of her movements. There is a slight difference in the range from the "mouse" position to the "ugly cow" position and from the "Yin tiger" position. Through the action range, Bai Xiaowen can calculate which Zodiac the pointer points to after each move.


    We should know that when Bai Xiaowen did not become an awakened person, he could reproduce the pharmacist''s pharmaceutical actions through abnormal memory, reproduce the complex pharmaceutical process and succeed in making drugs. At this time, after becoming an awakened person, his eyesight, ear strength and mental induction have been greatly improved. Although the light here is dim and far away, it is still nothing to re carve Gu Yulian''s action.


    Bai Xiaowen didn''t have any wrong thoughts, but he was prepared for everything. He still didn''t have 100% trust in Gu Yulian.


    After seven rotations, the bronze heavy door rumbled and vibrated, and slowly slid into the mountain wall. The surrounding mechanism holes are also quietly covered behind the slate.


    "Eh, there''s a light behind the door. Is there anyone inside?" Li Shuyi said in surprise on the team channel.


    A line of mermaids penetrated inside, Gu Yulian pressed the machine again, and the bronze heavy door closed slowly.


    Bai Xiaowen glanced at the wall lamps every few steps, and also replied in the team channel: "no, these oil lamps should never go out."


    "How much light oil does it cost?" Li Shuyi muttered.


    Bai Xiaowen said reluctantly, "by comparison, shouldn''t your concern be the problem of oxygen supply? The existence of these oil lamps shows that this arsenal is not airtight and can circulate with the outside air."


    The arsenal is very empty. There are no imaginary rows of bookshelves with Wulin secrets. There is only one stone pillar. Each stone pillar is thick enough for two people to hug.


    There are engraved pictures, or figures, or meridians on the stone pillars, and small words of notes beside them.


    Bai Xiaowen came to one of the stone pillars and saw four big words engraved on the top of the stone pillar: Wuxiang divine skill.


    There are a few lines of small characters at the bottom: Wuxiang divine skill, the first-class internal mental skill in the world. When you reach the state of great success, you can simulate and display the martial arts routines of various schools at will, and the power is more powerful. The poor effect of martial arts simulation of artistic conception is a deficiency in the United States - shachi.


    The following is a diagram of the meridians of the human body, as well as the notes.


    Bai Xiaowen was so absorbed that Gu Yulian said with a smile: "the Wuxiang divine skill was carved by the second generation of shachi palace leader. If you want to achieve the internal mental skill, you have to work hard for ten years. Childe Bai has missed the best age to cultivate internal skill. Even if you start working hard now, it''s too late."


    Bai Xiaowen moved in his heart and said, "since you know I can''t practice, where is the sincerity you gave me?"


    Gu Yulian said, "internal mental skill is hard to learn. However, there are martial arts experiences of past palace masters in the arsenal. Any martial arts can dominate for a time. Young master Bai just needs to choose a routine martial arts without internal skill cooperation."


    While talking, Gu Yulian walked to the side of one of the stone pillars and gently knocked on the stone pillar: "Just like this Liuyun sword technique, it is a unique skill of the town sect of the Jiuhua sect. When you practice it to a great level, the sword path moves like clouds and flowing water, which is enough to be listed in the top three of the world''s fast swords. The best thing is that Liuyun sword technique does not need internal skill assistance, but only requires the user to be flexible and strong enough to withstand the load brought by extremely high sword speed."


    Bai Xiaowen nodded silently. Liuyun sword must be a type of increasing attack speed in the process of casting, which is more suitable for Li Shuyi.


    When Bai Xiaowen heard "the top three fast swords in the world", he remembered one thing and said, "is the martial arts collected in this arsenal complete? Is there a water cut-off sword technique?"


    Gu Yulian said with a smile, "I knew that childe Bai would ask this question. There is a collection of water breaking sword techniques, but there is no matching key to water breaking sword meaning only because of its swordsmanship routine. Moreover, even if you have no internal skill, you can''t practice water breaking sword meaning."


    Bai Xiaowen said, "how can people like me practice internal skills?"


    "One word, difficult."


    Gu Yulian shook his head and said, "you are an adult and your meridians are blocked. If you want to cultivate internal skills, you need to open up the meridians first; and the premise of opening up the meridians is to have internal strength. This itself is an unsolvable problem."


    "Can''t we use external force?" Bai Xiaowen was itching. Isn''t there a super strong man in the martial arts novel to help get through the bridge between Ren and Du.


    Gu Yulian obviously understood Bai Xiaowen''s meaning and said with a smile, "when an external force enters the body, the resistance increases ten times. For example, it''s hard to do what you want, even though it''s hard. It''s only possible for me to do it unless I''m a top expert of my master''s level. However, it''s impossible to ask that kind of expert to help me get through the meridians."


    "What about swallowing natural materials and earth treasures? Such as Millennium Ganoderma lucidum." Bai Xiaowen fully carried forward the spirit of asking if he didn''t understand. Han Xu also showed his bright eyes.


    Gu Yulian couldn''t understand Bai Xiaowen and others'' infinite desire for internal skills, but reluctantly said, "first of all, Tiancai and Dibao are extremely rare. Even if the medicine is too overbearing, it will break your meridians before opening up the meridians. If you swallow it rashly, the magic medicine is poison."


    "OK." Bai Xiaowen hasn''t given up, but it''s hard to ask again.


    As they walked in the arsenal, Gu Yulian kept explaining the origin of martial arts on stone pillars. Some of these martial arts are the unique skills of the town sect collected by the previous palace masters who challenge all factions, but more are the unique skills created by the previous palace masters by integrating the strengths of hundreds of families.


    It can be said that the martial arts recorded on each stone pillar are the best martial arts in the position of sword song, and the lowest is the same level as Ying Jianfan''s "flying shadow sword".


    At the end of the road, there were many blank stone pillars, which were no longer engraved with martial arts.


    At the end of the arsenal, there is a jade bed with bowls and basins and other daily necessities, which adds a trace of life to the solemn Arsenal.


    Gu Yulian came near the jade bed and touched a stone pillar recording martial arts and said, "this is the fifth generation palace master, the place where Shifu records martial arts. She always had a big regret, so she was worried. She spent little time in the Arsenal and left the least martial arts records."


    Bai Xiaowen approached the jade bed, but Gu Yulian stopped him.


    "Stay away!"


    Gu Yulian whispered, "in the jade bed, there is a unique skill of the blood god palace, blood nerve. Only the palace master can learn this magic skill."


    Bai Xiaowen was slightly stunned, then smiled and said, "girl, you really confide in Bai Mou. You don''t even hide this secret. Aren''t you afraid of my sudden turning over and robbing blood nerves?"


    Gu Yulian was calm and abnormal: "what''s the use of taking blood nerve? You can''t cultivate yourself. Besides, even if you can cultivate to an invincible state, you can''t get out of this arsenal."


    Bai Xiaowen glanced at the bronze gate of the arsenal: "to go out of the arsenal, you also need to start the mechanism?"


    Gu Yulian nodded. Obviously, only she knows how to open the mechanism. No wonder she is so calm.


    Bai Xiaowen shook his head and said with a smile, "no wonder the girl closed the door after entering the door. It''s really careful."


    "For such a clever man as Mr. Bai, it''s not good to be careless." Gu Yulian smiled.


    Bai Xiaowen said, "well, it was just a joke. The girl said that blood nerve is a unique skill that only the palace master can learn. Will the girl herself?"


    Gu Yulian shook her head, "master forbids me to learn."


    "It''s a little troublesome," Bai Xiaowen frowned. "If you can learn blood nerve, it should be much easier to get the recognition of the three peaks and four valleys leader. In a sense, it should be a symbol of the palace leader and represent strength."


    Gu Yulian said faintly, "the ''forging jade formula'' created by master is also a first-class internal skill."


    "Since you are designated as the next palace leader, you might as well open the jade bed and learn blood nerves. This will greatly reduce the difficulty of seizing power." Bai Xiaowen said.


    Gu Yulian shook her head, "master forbids me to learn, so I won''t learn."


    "Yin imperial concubine is not here..."


    Bai Xiaowen wanted to say more. Gu Yulian waved and stopped: "I''m not a obedient apprentice and often annoy Shifu. But I will never do what Shifu doesn''t allow me to do. She said that the blood nerve is too bloody, contrary to the harmony of heaven. People practicing either live alone or die a bad end. That''s why she worked hard and created the jade forging formula to teach me."


    Bai Xiaowen realized that as an ancient Chinese position, the sword and song position paid attention to the relationship between teachers and disciples. It is said that he is a teacher one day and a father all his life. The disciples have great respect for the master.


    Think about the word "deceiving teachers and destroying ancestors". The sin of "deceiving teachers" is even equal to "destroying ancestors". We know how much influence this moral tradition of ancient China has.


    Of course, most masters also tried their best to treat their disciples as their own children, such as Yin Fei and Gu Yulian.


    "This blood nerve is really so evil?" Bai Xiaowen didn''t believe it. It was feudal superstition.


    Gu Yulian said, "master is right. Since the first generation of palace leader Sha Qianhai, every generation of palace leader has achieved unparalleled martial arts, but no family member can accompany him to the end. He is often unhappy and even dies suddenly in his prime. Even master is the same."


    "You said the Yin imperial concubine had a big regret. What''s the details?" Bai Xiaowen asked. "If it''s inconvenient to say, it''s OK."


    Gu Yulian''s tone was flat: "in fact, it''s not a secret. It''s OK to tell you in detail. However, as a disciple, I can''t talk about Shifu. I''ll tell you briefly: Shifu''s parents died at the hands of her favorite man."


    The three members of Bai Huang''s team were startled.


    Li Shuyi murmured, "it''s terrible. Doesn''t Yin Fei want to hate that man all her life."


    "Maybe it was an unintentional mistake, or someone planted a frame." Bai Xiaowen put forward another possibility from the perspective of men.


    Gu Yulian sneered: "planting a frame? Shifu saw with his own eyes that the man killed her mother, and her father was seriously injured and finally died. Hundreds of Wulin heroes witnessed this. What do you say about planting a frame?"


    "...." Bai Xiaowen has no words.


    He didn''t expect Gu Yulian''s reaction to be so fierce. It seems that Gu Yulian should sympathize with the experience of Yin imperial concubine, so he also has a deep hatred for that man.


    "Well, that''s it. Don''t mention it again."


    Gu Yulian soon restrained his mood and showed a faint smile again, just like flawless white Bi. She waved and said, "young master Bai, you have seen my sincerity. As long as you help me seize the power of the blood god palace, you can choose any martial arts here. Of course, it doesn''t include blood nerve."


    "OK." Bai Xiaowen nodded without hesitation.


    They left the Arsenal and walked along the underground secret road for seven or eight times. I don''t know how long. At the end of the secret road in front, there was a winding stone ladder.


    Gu Yulian went up the ladder and said softly, "do you know where the ladder exit leads?"


    Bai Xiaowen''s eyes flashed: "blood God peak?"


    Gu Yulian nodded slightly: "it''s not only the blood God peak, but also the main hall of the blood god palace, behind the throne of the palace master!"


    Bai Xiaowen took a breath: "my maid... Bai Rui is also in the blood god palace?"


    Gu Yulian said with a smile, "don''t worry, you''ll see her soon. She won''t lose a hair."
