The shape of the metal box is exquisite and elegant. The four corners are engraved with dragon patterns, and an exquisite animal head lock is set on one side.

    In the jagged tusks of the beast''s head lock, there is an irregular strange keyhole.

    Obviously, this lock is not a simple lock, and the things in it are not easily available to ordinary people.

    Otherwise, it would not be precious and important, locked in a silver box.

    Sure enough, I only heard the words of the big man with disorderly hair from behind me: "this box is from the jinyufang in the imperial capital of the great Jin Dynasty. It is said that even in the Forbidden Palace court and the palace of princes and ministers, many utensils are produced by the jinyufang. This box needs at least ten liang of silver."

    "Of course, this box is not the most precious. What is more precious is the lock matched on this box."

    Zhang Heng looked at the big man with disorderly hair and was not interested: "is this lock very precious? What else does this lock say? Or is this lock also from jinyufang?"

    After hearing this, the bald man smiled and said, "if this lock also comes from jinyufang, it''s not precious."

    "This lock is called Qiqiao lock. It''s a strange yuan soldier."

    "It is said that every Qiqiao lock has only the key to open it. If you lose that key, even the person who created it will be difficult to open it intact."

    "If someone forcibly opens it, the strange yuan force contained in the lock will instantly turn the things collected into ashes."

    "Even everything within ten feet of it will turn into ashes."

    Hearing the words of the bald man, Zhang Heng couldn''t help thinking of a book he occasionally turned to when looking up materials on the first floor of the wanjuan building. The book was called the record of strange stories of the world.

    One of them mentioned a strange man named "Qiqiao fairy boy".

    It is said that this man is naturally different from ordinary people. It is difficult to absorb the vitality of heaven and earth and condense into a sea of Qi. It is difficult to be a brave man all his life.

    And he himself is not willing to be mediocre.

    So he read a lot and finally created a different casting technique.

    With the help of this casting technique, he can turn the vitality of others into his own use, and with the help of wild ideas, he has invented countless wonderful things.

    Among them, Qiqiao lock is one of them.

    Zhang Heng looked at the box with Qiqiao lock in front of him and said, "it is said that Qiqiao lock was made by Qiqiao fairy boy. He only made seven such locks in his life, so it is called Qiqiao lock. One of the seven locks was installed on the door of the royal secret library by the royal family of the Jin Dynasty."

    "Unexpectedly, I Zhang Heng can be here today and see another pair of Qiqiao locks."

    "I''m a little curious now. What precious treasure is there in the box with Qiqiao lock? It''s incredibly hard to seal such a treasure with Qiqiao lock."

    After hearing this, the bald man laughed and said, "there''s no treasure. It''s the inheritance medical code of the elder magic doctor."

    The disorderly haired man then smiled and said, "the Lord of wolves ordered us to give it to you."

    "After you accept it, you can practice the above inheritance by yourself. If you are not interested, you can also give it to someone you think is suitable."

    Zhang Heng was stunned. He thought that the promise of the Lord of wolves that day was just to make him work hard and talk in vain.

    I didn''t expect the other party to do what they said.

    While talking, the bald man had taken out a key from his arms and sent it to Zhang Heng.

    Zhang Heng took it in his hand and looked at it carefully.

    The key was exquisite and strange, like two snakes circling up.

    Moreover, Zhang Heng also vaguely felt that there was a strange element force in the key, which was running slowly and continuously, as if it had become one of its own.

    Zhang Heng reached out and inserted the key into the lock hole of Qiqiao lock.

    Seven full turns to the right.

    I vaguely felt that the strange element force in the key in my hand slowly disappeared between the rotation of the key, and finally disappeared.

    After Zhang Heng found that he could no longer turn it, he pulled out the key.

    As soon as the key was pulled out, Zhang Heng heard the abnormal sound of "click click" inside the silver box.

    Such a strange noise made a full number of breaths before it finally stopped.

    Finally, Zhang Henggang reached out to open the box. Unexpectedly, with a click, the box had been opened slowly by itself.

    Suddenly, everything in the box appeared in front of Zhang Heng.

    There are two things in front of us, one is a pill bottle and the other is a jade book.

    The Dan bottle is milky white and in the shape of a treasure gourd. On the belly of the bottle is a small paper label with two wild small words - Changsheng.

    Zhang Heng took a thin copy of the jade book in his hand, but found that the weight was surprisingly heavy. On the cover of the jade book, there were also two wild small characters - medical classics.

    Seeing the two things in front of him, Zhang Heng couldn''t help sighing: "The magic doctor is worthy of being a magic doctor. He dares to directly name his inheritance as'' medical code ''. You know, medical code has always been the general name of medical classics left by countless famous doctors in ancient and modern times. The magic doctor named his inheritance as medical code. Doesn''t it mean that he is confident that his medical strength alone is comparable to that of countless miracle doctors and medicine saints in ancient and modern times?"

    Thinking of this, Zhang hen couldn''t help looking at the bald man and the man with disorderly hair. He found that they were not eager to try in the face of the world-famous inheritance of magic medicine.

    Zhang Heng couldn''t help but wonder and then tried, "do you want to have a look?"

    After hearing this, the bald men not only didn''t come forward, but immediately avoided it, waving their hands and retreating.

    It seems that what is in front of them is not the inheritance of magic medicine that makes people without Mathematical Medicine feel hot and want to get it by all means, but a demon alien who will hurt people''s lives and suck at the bone and marrow at any time.

    Zhang Heng saw it and looked at them more puzzled: "you..."

    The bald man saw the confusion on Zhang Heng''s face and immediately explained, "we can''t see it."

    "Why not?" the expression on Zhang Heng''s face was even more confused.

    "Because this is what the magic doctor said. We must listen to the magic doctor."

    The disorderly haired man then added: "in those years, there were more than 20 people who followed the magic doctor to the West River Valley and settled down."

    "When someone saw that the magic doctor was dying, they had evil thoughts. They wanted to kill the magic doctor, seize the inheritance and leave here."

    "But they just saw the magic doctor himself. The magic doctor just turned around with his hands on his back and smiled at them. In a twinkling, they all died in front of the magic doctor for no reason..."

    While talking, the man with disorderly hair recalled his past experience. The more he told, the more his voice trembled. In the end, his voice was low and inaudible.

    The bald man on one side also looked pale, but he could barely speak. Then he sent out the man''s words and said, "after that, anyone who doesn''t obey the orders of the magic doctor will die without a burial place."

    "When the magic doctor died, there were five of us left."

    "Three of them realized that the magic doctor was dead. They didn''t have to follow the orders of the magic doctor. They stayed in the West River valley forever in their lifetime."

    "The two of us were also excited about this idea, so after the three left, we secretly followed each other behind..."

    When the bald man said this, his face was sweating. At the same time, he couldn''t help swallowing his saliva. Then he went on and said, "after leaving the green Wolf cliff at the beginning, the three people quickly rushed to the exit of the West River Valley. At first, nothing happened."

    "The two of us began to hesitate, thinking whether to leave with the three until..."

    Speaking of this, the bald man suddenly didn''t go on, but looked straight into the distance.

    The bald man looked in the direction of the canyon exit on the periphery of the West River Valley.

    "Until what?" Zhang Heng couldn''t help looking at the bald man and asked.

    At this time, the bald man seemed to fall into some terrible memory, his hands trembled uncontrollably, his mouth opened, but he couldn''t say a word.

    At this time, the man with disorderly hair on one side seemed to have recovered. He saw the bald man. Then he continued to say, "we didn''t understand that the magic doctor is a magic doctor until we got near the valley mouth. Even if the dead magic doctor, we must not disobey his orders."

    "What do you see?" Zhang Heng asked.

    "We saw that the three men walked into the narrow mountain path at the exit of the valley. The moon was in the sky that night, and the silver moonlight shone on the valley path. They saw the three walking side by side without talking. Obviously, they were also worried about betraying the magic doctor."

    "As we watched the three go farther and farther, we suddenly found that the figure of the three seems to be getting smaller and smaller."

    "Moreover, we can confirm that this is not because they are getting farther and farther away from us, so they look smaller, but that they themselves are gradually shrinking at the speed visible to the naked eye, while the three people who are moving farther and farther away in the valley seem to be unaware all the time."

    "Suddenly, a night wind blew. It was midsummer that night. It was a very pleasant thing, but it made my hair stand on end."

    "Because I suddenly saw that with the evening wind blowing, the hair on the heads of the three people suddenly fell from their heads like weeds."

    "The hair on the three heads flew down. We immediately found that there was only a translucent oil skin left on the three heads. Under the oil skin, their skulls were clearly visible. We even saw half of the spine wrapped by the oil skin above their collars."

    "I don''t know when most of the flesh and blood on these three people have disappeared. Under the moonlight, the three people walking in the valley are like three skeletons walking under the moon, and they seem to be unaware all the time."

    "Later, we only heard the click sound. As the three walked, it came from the valley with the wind. It should be the sound of their foot bones knocking on the mountain road."
