At the end of the Ming Dynasty, Cangmu Mountain in the southeast.

Yakushi Valley, Yakushi Cave.

"Li Yu, a disciple of the helmsman of Guihongmen, took the liberty of trespassing into the Valley of the Pharmacist and asked the pharmacist to give him medicine and save my helmsman. I would like to be rewarded with ten thousand gold! ”

A young man in a blue shirt stood in front of the cave, clasped his hands into fists, and chanted aloud towards the entrance of the cave.

Guihongmen, one of the most mysterious assassin organizations in the rivers and lakes, is said to have originated in the late Warring States period and was founded by Jing Ke's disciples. After thousands of years, there have been many heroes in Guihongmen, and the branches are all over the land of China, and the tentacles extend from the court to the mountains. According to the legend of the people, Guihong swordsman eliminated evil and promoted good, helped the needy, and could be called a hidden man who walked for the sky. Some of the kings of the past dynasties wanted to return to Hongmen under their command and drive them into eagle dogs, and some regarded returning to Hongmen as a great disaster and wanted to get rid of them quickly.

Li Yu is a young hero in Guihongmen. He was born as an orphan and was adopted as a righteous son by Han Zhi, the helmsman of the Hongmen Cangmu Helm Division, since he was a child. He has been practicing martial arts with his senior brother since he was three years old, and because of his talent and intelligence, coupled with the dictation of Han Zhi, he quickly became a leader among the younger generation of Guihongmen. Don't look at him as only 18 years old this year, but he has already made a great reputation in the rivers and lakes.

At the end of the Ming Dynasty, Shenzhou can be described as internal and external troubles. There has been a severe drought in the north for many years, and the people are struggling to make a living, and the people are in turmoil; The war in Liaodong continued, and the border city of Guanning was in danger. The southeast coastal area was not very peaceful, taking advantage of the Ming court's lack of time to look eastward, the Japanese and traitors were entangled, constantly harassing the city and harming the people.

At this time of national crisis, Han Zhi led the people who returned to Hongmen to fight against the Japanese and protect the peace of the party. Who would have thought that in an anti-Japanese battle in Yuhai City, Han Zhi was injured by a traitor with poison, and his life was in danger.

Luo Gensheng, the treasurer of the Jicui Hall of the Yuhai City Medical Center, came to inquire and recognized that the poison in Han Zhi's house was the secret medicine Wuying poison that was not spread in the pharmacist sect. According to Luo Gensheng, there are only two people in the rivers and lakes who can make this poison, one is his mentor and the current head of the pharmacist sect, Fan Wuxian, and the other is his uncle Tian Wuxian. Tian Wuji has already betrayed his master because he is not satisfied with his senior brother to take over the position of head of the family, and there were rumors that he sold himself to the Japanese a few years ago, judging from the poisoning of Han Zhi this time, this rumor is not groundless.

Luo Gensheng said that there was only one way to cure the Shadowless Poison, which was to go to the Pharmacist Valley to ask the pharmacist Master Wuxian for medicine. Fan Wuxian has been living in seclusion in the Medicine Master Valley for 20 years, and there is a poison array laid by Fan Wuxian within a radius of ten miles from the Medicine Master Valley, which ordinary people cannot enter at all.

Li Yu volunteered to go to the Medicine Valley, meet Fan Wuxian to get the antidote, he took Han Zhi's helm master token as a token, and raised a bag of gold and silver treasures as a gift, and then rushed to the Medicine Master Valley alone. Before leaving, Luo Gensheng gave him a pill to resist the poisonous gas in the Medicine Master Valley, and as for the other dangers, he could only rely on Li Yu to resolve them.

Along the way, there were countless difficulties, and Li Yu finally came to the pharmacist cave where Fan Wuxian lived.

The door of the Medicine Master's Cave was open, and there was not a sound inside. Li Yu didn't dare to make a mistake, stopped and stood still, and reported loudly inside. Even shouted more than a dozen times, there was no reaction in the cave, thinking of the legendary Chinese medicine teacher without a trace, both righteous and evil, moody character, Li Yuya bit his heart, said "offended", and already had a short sword with a length of a ruler in his hand, and slowly walked into the hole.

In the line of assassins, it is common to crack various mechanisms and go deep into dangerous places, and since Li Yu chose to come to the Pharmacist Valley to seek medicine, he has already put life and death out of the way. To his surprise, he didn't encounter any obstacles, and walked to the stone chamber of the Medicine Cave.

The stone room is boxy, two zhang long and wide, and two zhang high, and there is no feeling of sullenness in it. Li Yu didn't see the candle flame or the window, but the cave was not very dark, just like the dusk outside.

There is a platform in the middle of the stone room, and on the top of the platform sits cross-legged an old man, with his hands on his knees, a smile on his face, and a pair of eyes slightly closed, as if he had settled down. A few steps in front of the platform, there were several futons, which looked like they were used for kneeling. Li Yu hesitated for a moment, stepped forward, knelt down on the futon in the middle of the moment, respectfully kowtowed to the old man on the stage a few times, and then told Han Zhi about the poisoning from beginning to end, and finally said:

"Li Yu implored the pharmacist to give him the antidote to the shadowless poison, and Li Yu was willing to reward him with ten thousand gold."

The old man on the stage did not react at all.

Li Yu took out a bunch of jewels from his backpack, put them in front of him, and then kowtowed again, lying his head on the ground, waiting for the old man's answer.

For a long time, there was still silence in the stone room, Li Yu listened attentively, and was surprised to find that he could only hear his own breathing, but the old man did not make a sound at all. Li Yu's heart moved, he dodged up, rushed to the stage, stretched out his hand under the old man's nose and touched it, he couldn't help but be dumbfounded, it turned out that the old man on the platform had been angry for a long time.

What can I do?

Li was panicked, he looked around, and suddenly found that there was a folded yellow paper in front of the old man, he picked it up and unfolded it, and looked at it through the hazy light, with four lines of words written on it:

"Come in my door and bow down to thank the Master; The head of the family is a treasure, and the love is passed on. ”

Under it, there are a few lines of small words, saying that since the person who saw the note was able to enter the Medicine Master Valley without fear of the poison array, he was naturally a descendant of the Medicine Master Sect, and if he could think of coming to visit him, he must be a filial apprentice. He had two volumes of the secret "Medicine Master Scripture" and a token of the head of the Medicine Master Sect, which were hidden in the stone wall, and a batch of medicinal herbs and pills accumulated over the years, all of which were passed on to the disciples who first entered the Medicine Master Cave.

And such a good thing?

Li Yu was secretly happy in his heart. The head token of the Medicine Master Sect, he is not interested, but he must bring it back and give it to Han Zhi, Han Zhi should be useful. The Medicine Master's Book is obviously the secret of the Medicine Master's various use of poison and detoxification, and with the secret in hand, why worry about not being able to solve Han Zhi's poison. As for those medicinal herbs, pills and the like, Li Yu didn't plan to move, this is the inheritance of the pharmacist sect, or wait for the real pharmacist disciples to use it.

Thinking of this, he began to search the stone chamber with confidence and boldness, and soon found a mechanism on a wall, and after activating it, a wall cabinet appeared, in which many bottles and cans were hidden, and the most obvious place was a wooden box with a simple appearance.

Li Yu took the wooden box and opened it to see that there were two books and a jade plaque inside, and the name written on the book was the Medicine Master's Benjing. Li Yu closed the box and was about to close the closet, when he suddenly saw that there was a note in the place where the wooden box was originally placed, which was obviously pressed under the wooden box, and he didn't pay attention to it.

With curiosity, Li Yu unfolded the note. There was a single line written on the note, and the font was so small that it was impossible to read in the dim light. Li Yu took out the fire sickle and Song Ming lit the fire, and looked closer, but the words on it were extremely improper:

"Good apprentice, you must be happy to pass on the position of head of the family to your teacher, right? With such a great benefit of being a teacher, should I stay with him as a teacher? I know that you are uncertain, and you definitely don't want to listen to the words of the teacher, and you have refined a thousand-year-old drunk for the teacher, which can make you stay here and accompany the teacher for a thousand years. The prescription and antidote are as follows...... By the way, this medicine is colorless and odorless, and it will be fired immediately when it encounters fire, are you watching it with a candle lit now? ”

Candle? Li Yu raised his eyes and saw the burning Songming in his hand, and suddenly thought of something, he threw Songming on the ground, stepped on it with his foot, and was about to run out of the hole, when he felt weak, and the whole person fell to the ground crookedly.

This old thing!

This was Li Yu's last thought before he lost consciousness.

At the entrance of the cave, there was a loud bang suddenly without warning, and a heavy stone door fell from the top of the stone cave, sealing the entrance tightly, and then, the light of the stone chamber in the cave disappeared at once, and the entire stone chamber fell into boundless darkness......
