Looking at the sword tower, all Liu Zixuan thought about was to hurry up and get the Netherworld Flint to save the beautiful master.

Although he didn't know what the Medicine Immortal Sect wanted for that Netherworld Flint, it was the only thing that could save the beautiful master, so no matter how difficult it was, Liu Zixuan had to get it.

Liu Zixuan turned his head and asked, "Elder Qing, I heard that there is a sword mound in the Xuanjian Sect, is it in this sword tower?"

"You know a lot. Qing Lao smiled and nodded: "Yes, the three underground floors of the sword tower are the sword mounds. ”

"Then take me in and have a look. Liu Zixuan rubbed his hands and smiled.

"It's okay to take you in, but I guess you won't be so excited when you get in. Qing Lao smiled meaningfully and directly opened the door of the Sword Tower.

Suddenly, I saw a three-meter-high sword in the middle of the first floor, but it was made of stone, standing there like a sculpture.

"There is a rule for cleaning the sword tower, you have to go down from the top, so if you want to see the sword mound, you have to clean the eleven floors above first. Qing Lao said.

"No problem. "Thinking that the sword mound is here, Liu Zixuan doesn't care whether he is tired of sweeping the floor or not.

"Let's go. ”

"No, your old man can rest here, and I'll finish this little work in a while!"

Liu Zixuan snatched the broom directly from Qing Lao's hand and ran directly to the top floor.

Qing Lao shouted from behind: "It's okay to clean, don't touch those swords." ”

"Don't worry, the master's swords are better than theirs!" Liu Zixuan didn't care about those swords.

The reason why Qing Lao was not allowed to go up was because he was worried that Qing Lao would be too harsh, and if he didn't go up at the moment, Liu Zixuan could clean up one layer with three strokes and five divided by two!

The top floor is full of books, Liu Zixuan took a brief look, most of them are some Heart Sutras or sword books and the like, while the lower floors are some meditation rooms, and some are rooms full of all kinds of swords, but they are also messy.

About twenty minutes later, Liu Zixuan walked back to the first layer from the second floor and wiped the sweat from his forehead: "Okay!"

"Maba, you must not have cleaned up so quickly. Qing Lao scolded angrily.

Liu Zixuan smiled sheepishly: "How is that possible, I am very careful and serious." ”

"You guy!" Qing Lao glanced at Liu Zixuan: "Then follow me to the Sword Shrine." ”

As he spoke, Qing Lao walked to the sculpture of the sword, gently turned a stone protruding from the sword god, and suddenly a downward step appeared on the ground.

Liu Zixuan walked down with Qing Lao, and when he was halfway through, he was suspicious: "Qing Lao, don't you want to go down from the top? How can you go directly to the third basement floor?"

"The first and second floors of the basement are forbidden places for the Sword Tower, so you don't need to clean it, let's go directly to the Sword Shrine. When Qing Lao said this, his face was extremely solemn, as if he was unwilling to mention the first and second floors.

Liu Zixuan didn't care about this, waved his hand, and continued to walk with him.

The further down, the higher the temperature, and after a while, Liu Zixuan's body sweated a lot, and an extremely depressed feeling also swept through his body.

"Whew!"

Hearing Liu Zixuan gasping for breath, Qing Lao scolded: "What's the matter? I was still yelling down just now, I can't stand this temperature? If you are asked to go to the flint, you will not faint directly." ”

"What kind of fire is this, the temperature is so high, it feels like it's going to be cooked. Liu Zixuan asked.

"The fire of the Nether Flint is different from ordinary flames, it cannot be extinguished with water, and in a word in mythology, the flame emitted by the Nether Flint is the true fire of Samadhi!" explained Kyelao.

"Then can this flint stone have other effects besides forging swords?"

"Listening to you, it seems that you are very interested in the Nether Flint?" Qing Lao asked rhetorically.

Liu Zixuan shook his head: "It's not a curiosity for Shanhan to enter Beijing." ”

Qing Lao glanced at Liu Zixuan with disdain and explained: "The Netherworld Flint has existed since the establishment of the Xuanjian Sect, but at that time, the flint was very large, the size of a room, and with the passage of time, there is now a very small piece left, as for his role, in addition to the sharper sword cast, it is also of great use to people who are good at alchemy." ”

"Alchemy?" Liu Zixuan raised his eyebrows.

"Ordinary flame alchemy, there will be a certain failure rate, the color of the pill is not good, or the effect is not enough, etc., but with the Netherworld flint, no matter what pill is refined, it will be successful at one time, and it is the best color effect. Therefore, this thing is also coveted by the alchemy master. ”

Listening to Qing Lao's words, Liu Zixuan suddenly realized, so it made sense.

Although the medical immortal sect is said to be all healers, the masters of the medical path are very good at alchemy, and they want this netherworld flint, it should be to refine the very powerful pill in their eyes.

Seeing Liu Zixuan nodding, Qing Lao was curious: "What's the matter, it seems that you can also do alchemy?"

"I know a little bit about it, and I have learned some medical skills before. Liu Zixuan didn't hide it.

"Do you know how to heal?" said Qing Lao, ......who suddenly stopped.

"Can it be anything? Are you sick?" Liu Zixuan stepped forward to take a look, although Qing Lao said that he was full of old age, but he was not sick on the surface.

"Forget it, let's go out and talk about it. A different color flashed in Qing Lao's eyes, and he pointed forward: "It's here!"

Liu Zixuan turned his head to look, and there was a huge melting pot in front of him.

Beneath the steps he was on were all floating, unfinished swords, of varying lengths, and underneath them was a stone that was half red and half cyan, small but immanently unapproachable.

The scene in front of him was very macroscopic, hundreds of swords were suspended in this space, and below it was an extremely strange stone. It's shocking.

What a spectacle it would be for a master to harness so many swords to attack at the same time.

Liu Zixuan sighed, and his gaze finally fell on the stone, about the size of a fist.

And that's what he's going to take, Nether Flint!

Qing Lao smiled: "Don't look at the small stone, even if you are a master of the Emperor Realm, you can't pick it up." ”

"Why?" This sentence undoubtedly hit Liu Zixuan a little.

Qing Lao didn't say much, but picked up a piece of scrap iron next to him and threw it directly on the stone, just a breath, the iron directly turned into molten iron, and it was against the bottom of the deep pit.

The corners of Liu Zixuan's mouth twitched a few times, the iron melted so quickly, if he put his hand on it, I'm afraid there wouldn't even be any bones left.

In this case, how could he take the Nether Fire Stone away?

"Okay, you've seen what you should see, let's start cleaning, gather all these scrap iron next to it, and then simply sweep it. Qing Lao patted Liu Zixuan's shoulder, and he sat directly on the steps.

This chapter is made up for yesterday. Leaves always do what they say. Today's fifth watch is over, good night everyone. The weather is getting colder, so remember to dress extra in the morning and evening to prevent colds.
