"What price?" Lin Tianyou hurriedly asked curiously, he only knew that there were many benefits to entering the three gates of heaven, earth and man, but he had never heard of the price.

In fact, even Ye Qing is the same, so many people outside are arguing and wanting to enter the three gates of heaven, earth and man, aren't they all for the sake of achieving the supreme and dominating the world?

"Hehe......" An Shiping smiled bitterly: "I can't say this price, once I say it, it will inevitably cause chaos in the world." However, you must remember my words, unless you have to, do not enter the three gates of heaven, earth and man. If you really want to go in, then you have to enter the Heavenly Gate no matter what!"

Seeing that An Shiping said so resolutely, Lin Tianyou nodded and said, "Master, don't worry, I haven't thought about this matter of heaven, earth and man." I'm just a doctor, and it's enough to learn better medicine and treat more patients. ”

An Shiping smiled with satisfaction, Lin Tianyou's idea made him even more satisfied with Lin Tianyou.

"If you think like that, I'm so relieved. An Shiping said with a smile: "Although I can't say anything about the three doors of heaven, earth and man, I can also give you a little bit of a letter." Let's put it this way, from ancient times to the present, the three gates of heaven, earth and man have existed for thousands of years, but do you know what the final result of those who enter the three gates of heaven, earth and man is?"

"What is it?" Lin Tianyou said strangely, this kind of thing, but no one has ever said it. They only know that these people come out either rich or expensive, either to become rich, or to become supreme masters, or to become a generation of founding emperors. However, no one knows the final result of these people.

An Shiping said softly: "These people are all dead in the end!"

"Are they all dead?" Lin Tianyou was stunned for a moment, and then said, "Master, this ...... It's not strange, is it? People die, it's been so many years that it's strange that they don't die. ”

"Hmph. An Shiping shook his head lightly and said, "The death I said is not so simple. If you have the chance, look at the graves of these people and you'll know what I mean. ”

"Their graves?" Lin Tianyou was surprised and said, "What's wrong with the grave?"

"I can't say the rest anymore, it will cause confusion. You know that even if you forget about it, don't spread it out, otherwise, the world will be in chaos. An Shiping waved his hand and continued: "Okay, now I'll tell you about Yaowang Mountain." This Yaowang Mountain, I found Shakya Wuji and the True Buddha, joined forces with them, and arranged a large array to seal the mountain. This mountain-sealing array will always exist. Unless it's someone I give permission to, or someone with a miracle doctor's post, no one else wants to come in. You are my apprentice, I will pass on Yaowang Mountain to you, and you are the master of Yaowang Mountain. In the future, without your permission, outsiders will not want to enter Yaowang Mountain. Therefore, Yaowang Mountain is your own thing, and no one can take it away!"

Lin Tianyou didn't refuse again this time, because An Shiping just said very clearly that Yaowangshan could only give him one person. At this time, he didn't want to make this master feel uncomfortable.

"After Yaowang Mountain was passed to you, the only one who could enter and leave Yaowang Mountain freely was Xiaolu except you. Others want to enter Yaowang Mountain, unless they are holding a divine doctor's post. An Shiping looked at the eight divine doctor posts next to him and said, "This divine doctor post is my logo and the symbol of my divine doctor's door." I hope that you will pass on this divine medical post and give it to those who are kind to you. Those who hold the Divine Doctor's Certificate, they can enter Yaowang Mountain, and they can find you to treat their illnesses in person!"

In An Shiping's era, the divine doctor post was used in this way, and the person who held the divine doctor post came to Yaowang Mountain and would be rescued by the divine doctor An Shiping.

Lin Tianyou nodded and said, "Master, I will definitely continue this tradition!"

"That's good!" An Shiping nodded and said, "Okay, I have finished explaining the things that should be explained." Now, I will pass on to you what I have learned. However, before that, we have to send those people out of the mountains first. ”

An Shiping said, waving his hand at the giant python Xiao Lu next to him, Xiao Lu understood, and immediately turned around and went out.

"Master, I have friends who are still on the mountain, why don't I go and explain to them first?" Lin Tianyou said: "If they can't find me for so long, they should probably be worried." ”

"No!" An Shiping shook his head and said, "I'll see you again when I go out in the future, and now the most important thing for you is to find out the road in the belly of this mountain first." Also, there are several most critical things in this Yaowang Mountain, you have to recognize clearly, this is the key to the Yaowang Mountain being able to grow so many medicinal materials. ”

An Shiping said, leading Lin Tianyou to walk in this cave and introducing Lin Tianyou to a qiē in this cave. Lin Tianyou followed behind him and wrote down everything in the cave with his heart. He knew that this was the key to whether he could get out of this mountain belly in the future.

The two walked for a while, and suddenly there was a chill in front of them, which made Lin Tianyou shiver involuntarily, and said, "Hey, why is it so cold here?"

"It's here. An Shiping smiled, pointed to a stone wall in front of him, and said, "This place is inlaid with a piece of 10,000-year-old cold iron, which I found from the cold place of the polar region. The 10,000-year-old cold iron is extremely cold, and it can turn the surrounding environment into a cold land. It is precisely because of this piece of 10,000-year-old cold iron that there can be an iceberg outside this Yaowang Mountain, which can grow a lot of cold-loving medicinal materials, such as the snow lotus and the like. By the way, there is also the ice toad, which especially likes the environment here. ”

If Ye Qing heard it here, he would definitely be surprised, because he saw the nine-leaf golden dragon blood lotus, as well as the ice toad. At that time, Ye Qing was still surprised, why was this the only place on this mountain so cold. Now I can be regarded as finding the answer, it turns out that it is because of this 10,000-year-old cold iron.

Lin Tianyou scratched his head and suddenly asked, "Ten Thousand Years Cold Iron, what is it?"

"To know what a 10,000-year-old cold iron is, you first have to know what a cold iron is. An Shiping said: "The so-called cold iron is actually a rare metal, which likes heat and can absorb heat. ”

"Is this still called cold iron?" Lin Tianyou said in astonishment: "Metal, which likes heat, should it be called hot iron?"

An Shiping glanced at Lin Tianyou and said, "You are not right, this kind of metal likes heat, and it will absorb the heat around it, so that the temperature around it will drop, so it is called cold iron." ”

"I see!" Lin Tianyou suddenly realized.

"The so-called 10,000-year-old cold iron is the cold iron that has been suppressed for more than 10,000 years in the polar cold places. In the polar cold, the temperature is very low, even lower than the temperature of cold iron. In this case, the temperature of the cold iron is released. The longer the suppression, the more heat is released from the cold iron. When you take out this cold iron and put it in a place with a higher temperature, the cold iron will quickly hold the heat from the outside, so that the temperature around you will drop and achieve the purpose of cooling. An Shiping said: "The cold land in this corner of my mountain was created in this way. The use of cold iron absorbs the surrounding heat, so that the temperature of the place reaches the temperature that those cold-loving plants can grow. ”

"Oh. Lin Tianyou completely understood, but soon said in surprise: "But, how much heat can such a piece of cold iron absorb, and how long can it last?"

An Shiping said: "Cold iron does not release heat quickly, and it does not absorb heat quickly. This piece of cold iron has been placed in the cold land for 10,000 years, so it will take 10,000 years to absorb heat. Therefore, you don't have to worry about the situation of Yaowang Mountain at all, this piece of cold iron is enough to support 10,000 years!"

"Ten thousand years?" Lin Tianyou's face was full of shock, and he said, "In this world, there is such a magical thing?"

"The world is so big, there are no surprises. An Shiping smiled and said, "In this world, there are more magical things than cold iron. ”

"What's even more amazing?" Lin Tianyou said curiously, "What is that?"

An Shiping said: "It is a weightless metal that can float in the air and is completely unaffected by gravity. ”

"And this kind of thing?" Lin Tianyou was stunned again, in fact, if Ye Qing was here, he wouldn't be so shocked. Because, the golden silk armor and the sun-shooting bow that Ye Qing had seen were all like this, and they had no weight at all.

Again, the world is so big that there are no surprises. An Shiping said: "When you go out in the future, you will see more things, and you will understand that what I said is true." As for the weightless metal, I hope you never see it in your life. ”

"Why?" said Lin Tianyouqi.

An Shiping sighed softly, shook his head, and did not explain to Lin Tianyou. What the reason is, only he knows in his own heart.

took Lin Tianyou all the way down, and An Shiping completely introduced the situation in the Medicine King Mountain to Lin Tianyou. The 10,000-year-old cold iron just now was enough to surprise Lin Tianyou. However, after that, he saw a piece of 10,000-year-old red iron, which once again subverted Lin Tianyou's worldview.

10,000-year-old red iron is completely opposite to 10,000-year-old cold iron. The 10,000-year-old cold iron has achieved a tip of the iceberg in Yaowang Mountain, and the 10,000-year-old hematite has achieved a high-temperature zone. In this high-temperature area, An Shiping planted a batch of heat-loving medicinal herbs, including an extremely precious fire crow, and these were stored in a way that even Ye Qing had never seen, and Lin Tianyou had never seen them.

While walking and introducing, after a long time, the two walked through the mountain corridor, An Shiping finally brought Lin Tianyou into a stone room, and said to Lin Tianyou: "Okay, this is my Dan room, and it is also the place where all my cheats and pills are placed." The scriptures you have read are just one of the hundreds of books in it. Only when you have learned all the books in this collection can you be considered to have inherited my inheritance completely. ”
