When the door was opened and the light was turned on, the originally dark library suddenly lit up. Looking at the large cabinet of books, Tang Rui was ecstatic. For me, this is truly a place of heaven!

The maid explained a few words and went out, leaving only Tang Rui with straight eyes in the huge library pavilion.

He shuttled between the major bookcases, only to feel dizzying and dazzled. "I've been here for two weeks, and I don't even know the history here, so let's take a look at the history first." ”

The front façade of the bookcase would have a letter on what type of books this column was, and Tang Rui quickly found the history book he was looking for in the third cabinet.

He flipped through it, and some of it seemed to be written in the previous words here, and he could barely read it, but slowly. He searched again and finally found a history book written in Chinese. Excited, he put a stack of books on the large desk, and then sat down on the big chair behind him and began to read.

The history of this planet is much shorter than the history of the Earth over there, and it's no wonder it's so backward until now. However, the history of this planet is very interesting, especially the great battles between people and demons are very thrilling, Tang Rui feels like reading a novel, he is completely fascinated, reading all the way, forgetting the time.

Finally finished reading a very thick history book, Tang Rui closed the book, and his mind was full of scenes of the battle between humans and demons, which was really full of blood and anger. He thought of the spiritual positions of the heroes in the ancestral hall of Tianhuo Gate, their names were all recorded, and those names were not just names, each name represented a legend, a heroic legend that will be passed on forever! Tang Rui only felt that his blood was stirring, if he could also become one of them, what a glory it would be! The passion of the heroes in fighting bloodily and the pride of killing the demons all made him deeply shocked and yearned.

"I also want to write my own legend! the legend of my white-haired boy Tang Rui!" Tang Rui gritted his teeth and shouted in his heart.

"Becoming a high-level alchemist makes it easy to find Uncle Long and Ke Xin. Collect nine Heavenly Stones at the same time, so that you can save Uncle Long!"

"I definitely want to worship 'Medicine Venerable' as a teacher, and I definitely want to become a senior alchemist!" Tang Rui only felt passionate, and couldn't help but shout.

"You kid has a lot of mouth. If you want to worship me as a teacher, it depends on whether you are qualified or not!" a domineering voice sounded.

Tang Rui was startled, looked around, it was empty, and there was not even a ghost.

"Auditory hallucinations?" he muttered.

"What are you hallucinating? I'm talking, I'm 'Yaozun'!" the domineering voice sounded again.

"'Yaozun'?!" Tang Rui was shocked, jumped up from his seat, and asked in a lost voice, "Where are you?"

"I'm underground. The voice softened slightly.

Tang Rui looked down at the smooth floor with a surprised face, "Underground, how do you go down?"

"It's very simple, there is an inkstone on the right hand side of the big desk, and you can turn the inkstone to come down. "The voice sounds like a kind old man.

When Tang Rui heard this, he looked up and saw that there was indeed an inkstone on his right, but it seemed that it had not been used for a long time, and all the ink in it had dried up. He held the inkstone in disbelief and turned it clockwise, but there was no response. He was slightly disappointed, and turned it counterclockwise, and the inkstone really turned!

As the inkstone turned, a large chunk of the empty space behind the bookcase began to slowly move away.

Tang Rui was surprised and delighted, and at the same time slightly frightened, he walked over slowly, and saw that after the large piece was removed, there was a bottomless tunnel below, and by the light, he could see rows of steps extending downward.

"Come down. Let the old man see what you are capable of, and you dare to speak wildly. The voice returned to its previous domineering fullness.

The old man's voice came out of the tunnel clearly, like a bell, extremely domineering, Tang Rui couldn't help but feel a shock to his body.

"Are you really a 'Medicine Venerable'?" Tang Rui asked in a loud voice despite his fear.

"Nonsense, who in the world dares to pretend to be an old man!" The tone was slightly angry, and the domineering was even heavier.

Tang Rui thought for a while, "yes, who dares to pretend to be the world-famous 'Medicine Venerable' if they have nothing to do." What's more, this is the Xia family, and it shouldn't be someone else who can know about this organ, it is the 'Medicine Venerable' Xia Lie. ”

He was relieved for a while, and was about to go down, when he suddenly thought of something, turned around and turned off the light with his mind control, and it was suddenly dark all of a sudden, and he used his night vision ability to go down. It was a little cold because the sun couldn't shine below, Tang Rui was wearing thin clothes, and he felt that his body was trembling a little, he cheered up and went down the steps.

Finally there is a wide underground passage ahead. As soon as Tang Rui stepped on the ground, there was immediately a sound of activity sounding, and the opening above his head immediately closed, and the surroundings were immediately pitch black. If he hadn't been able to see at night, he would have been absolutely scared to death at this time.

He stood in place and said in a loud voice: "'Medicine Venerable' senior, I'm here." ”

"Okay, at a young age, bold enough, it fits the old man's spleen and surname. The first level is passed. The voice was slightly joyful.

Tang Rui didn't expect to pass the first hurdle so easily, and thought about it again, "yes, if you were someone else, it was dark in front of me at this time, and I was absolutely stupid, how could I dare to speak loudly? Being able to see at night really helped me a lot." ”

Tang Rui began to walk forward slowly, and there was nothing unusual after walking for a while, but he didn't dare to let his guard down, and still walked forward very carefully.

Suddenly, a sound sounded, Tang Rui was startled, looked back, and saw countless thick red bows and arrows shooting towards him, extremely fast, and there was a sound of breaking the air in his ears, at this moment, there was also a sharp sound of breaking the air behind him, and when he turned around, there were actually countless red bows and arrows rushing towards him in front of him!

He was caught in the middle, and there was a dense rain of red arrows in front and behind!

He was horrified, his arms were spread, his hands were raised, and his mind moved, and two red fire dragons more than ten meters long roared out from the left and right palms respectively, and the red arrow rain met the red fire dragon, and was immediately burned to the point that only silver metal arrows remained. The metal arrow slowed slightly, and then continued to fly forward through the fire dragon, the arrow was small, but the number was huge, and it was enough to choke on itself.

At this moment of life and death, Tang Rui immediately mobilized all the vitality in his body and rushed to his palms, "Huh", "Huh", and two fire dragons flew out with a roar, but this time the fire dragon was cyan!

Tang Rui himself was taken aback, just now at the moment of life and death, he mobilized all the vitality in his body and struck out, and he actually directly reached the Qinghuo realm! But then he thought about it, he had already reached the ninth layer of the void, and he could have cultivated Qinghuo. The difference between green fire and red fire is just that more vitality is released. In the past two weeks, I have been practicing to speed up the countercurrent, and every time I don't dare to mobilize too much vitality because I am worried that my vitality will be exhausted too quickly, so my progress is so slow, in fact, I should have been able to break through the red fire realm a long time ago.

"It seems that being too cautious will bind you. Tang Rui thought to himself.

At the same time that Tang Rui was thinking about it, the metal arrow encountered the cyan fire dragon and was immediately incinerated and turned into powder.

Seeing that the cyan flame was so powerful that it could incinerate metal, Tang Rui was surprised and delighted. The red fire and the green fire are really not the same grade, and the white fire and heavenly fire below should be more powerful.

Finally saving the day, he lowered his arms and breathed a sigh of relief.

"The body is a fire genus, and the adaptability is also good, and the second level is passed. Let's go straight inside, and the third level will only appear after we meet. The voice was slightly joyful.

Tang Rui didn't dare to take it lightly, so he walked forward cautiously, and sure enough, as the old man said, there was no mechanism ahead.

After walking for a while, he saw a door appear in front of him, and the crack in the door was shining, and he walked forward slowly.

"Come in, the door is unlocked. "The sound is so clear that it seems to be right in my ears.

Tang Rui gently pushed the door, but there was no response, and as soon as he added strength, the door slowly opened.

In front of me is a spacious room, bright, with a large bed in the left corner, a tall and wide cabinet full of bottles and jars and various medicinal herbs in the opposite corner, and a tall bookcase with many books on the right corner. At this time, next to the bookcase, a ghost-like figure was sitting flipping through a book.

"It's coming. The man looked back, his hair was white, his face was wrinkled, but his eyes were radiant.

Tang Rui felt that this person was very different from a physical person, he was like a humanoid mist.

"Is this the state of the soul?" Tang Rui muttered.

"That's right, I'm the soul, so what?" the man's voice returned to domineering.

"Are you the predecessor of the 'Medicine Venerable'?" Tang Rui asked tentatively.

"Haha, the kid's mouth is quite sweet, that's right, I'm 'Medicine Venerable' Xia Lie. The old man laughed heartily.

Tang Rui was really excited, the "Medicine Venerable" he had been looking for was actually close in front of him! However, he immediately calmed down and said with a wary face: "'Medicine Venerable' senior, you said that the third level will only appear after the meeting, is it okay now?"

"Haha, it's not bad to be vigilant with a surname. Don't be afraid, come here, the third level is very simple. The old man smiled and beckoned to him.

Tang Rui always felt that it was not that simple, but he still walked over, looking around vigilantly as he walked.

"Come on!" the old man suddenly got up and grabbed his arm.

Tang Rui was startled and was about to break free, when he saw the old man close his eyes and quietly grab his arm, he wondered for a while and stopped struggling.

"Nine genera! Your kid was born with nine genera, and each of them has reached a stage of mending the heavens!" the old man's eyes widened and he looked at Tang Rui in surprise.

"Yes. Tang Rui nodded.

"Haha...... It's really strange that after twenty years, there is such a genius again! This is really incredible!" the old man said with an excited face.

"Senior, what is the third level?" Tang Rui looked curious.

"You've already passed the third level. The most important condition for becoming an alchemist is to have a trace of wood at the same time as the fire genus, and you will naturally be satisfied with the nine genera. The old man said with a smile on his face.

"So, did the senior agree to take me as an apprentice?" Tang Rui looked expectant.

"Of course, when I met Long Zhan, I really wanted to take him as an apprentice, but he had to cultivate and invent, and he didn't have the time and energy to learn from me, which was the biggest regret of my life. It's a blessing to meet you now. The old man said with a smile.

Tang Rui was pleasantly surprised when he heard this, and hurriedly bowed down, "Master is above, and I will be worshiped by the apprentice!"

The old man helped him up, and almost burst into tears with excitement, "Okay, good." ”

"Master, will I be able to learn alchemy from now on?" Tang Rui asked excitedly.

"I'm afraid it won't work today, it's almost dawn, you have to leave quickly, or someone will find out. From tomorrow onwards, you will come here every night to learn alchemy, and you can rest here when you are tired. The old man said with a smile.

Tang Rui was very surprised when he heard that it was almost dawn now, but when he thought that he had finished reading such a thick history book, it should have taken a long time, but he was fascinated and didn't notice it.

"Okay, Master, I'll definitely come. Tang Rui said, his eyes shining with a sharp light.

"Good boy, his eyes are so lethal, he fascinates thousands of girls, the old man likes it. The old man burst out laughing again.

Tang Rui was embarrassed and scratched the back of his head embarrassedly.

"Alright, no kidding, you can go ahead. The old man waved his hand.

"Yes, Master, take care. Tang Rui said respectfully. Then he walked out of the door, walked through the passageway, walked up the stairs, and was worried about how to open the exit, when suddenly the mechanism sounded, the exit opened, and a dazzling light shone in.

Tang Rui walked onto the ground while marveling at the ingenuity of the mechanism, and as soon as he got to the ground, the entrance was closed.
