Facing Xiang Tian was a huge square altar, but this altar was suspended in mid-air. And around it, there are also nearly 100 large bubbles suspended.

"Hehe, don't be so surprised, the current refining room has not yet reached the full picture, but the current scale is enough for you. The stele spirit took in Xiang Tian's expression and said with a slight meaning.

"I know this place isn't the whole picture, but it's too big! But when it comes to its size, it's about the same size as the cave hall. Xiang Tian couldn't help but sigh after looking around.

"Okay, I know this will have a big impact on you, but this is only the law of this space, and when you reach a certain realm, you will understand. The stele spirit said, and he slowly came to Xiang Tian and said, "As the stele spirit of the town boundary stele, I have the obligation to explain to you the rules in this refining room. The refining room, as the name suggests, is an important place to refine and purify items and improve their quality. ”

"Let's take the spirit jade in your cultivation realm as an example, the value of a medium-grade spirit jade is equivalent to a hundred low-grade spirit jade, but its spiritual energy content is only ten times that of it, and the same is true of the high-grade spirit jade. And this refining ground can transform the low-level materials in your hands into high-level materials. I saw that the stele spirit stretched out his little hand and said, "Give me ten low-grade spirit jades." ”

Xiang Tian didn't make a sound, and immediately counted out ten spirit jades to the tablet spirit.

"Look at it. The stele spirit checked the ten lower-grade spirit jades in his hand, and immediately shook it with one hand, and it was accurately punched into a bubble in mid-air. Then, the stele spirit stretched out his hand and pointed towards the central altar and shouted, "Refine!"

I saw a flash of brilliance on the altar, and the bubble wrapped in ten lower-grade spirit jades turned into ten streamers and threw them at the altar, and when the brilliance dissipated, a spirit jade with a strong aura suddenly fell from the altar.

"Medium-grade spirit jade!" Although Xiang Tian expected it, he couldn't help but exclaim when he saw this spirit jade.

"Wait a minute, there's more to it than that. The stele spirit stretched out his hand: "Give me an ordinary pill." ”

When Xiang Tian heard this, he obediently handed over a Qi Yun Pill.

The stele spirit pinched his fingers, and then threw the elixir into a floating bubble. The stele spirit also acted as before, and the bubble finally turned into a beam of light and threw it into the altar, and finally a cloud of mist fell from the altar.

"Dan Wu! It's a heavenly elixir!" Xiang Tian's divine sense swept away, but he told the bottom of this elixir.

Among the elixirs in the cultivation realm, the degree of purity of the elixir is different. It is divided into different levels, which are inferior, ordinary, superior, earthly, heavenly and spiritual elixirs.

After each elixir is refined, the elixir inevitably contains some impurities that are not beneficial to the user, and can be easily identified by refining by various means, so as to judge various grades.

Among them, the inferior elixir is the elixir in which the substance that is useless to the monk is more than 50 percent, and the purity is less than half; the ordinary elixir is the elixir with a purity between 50 and 80 percent, and the best elixir is more than 80 percent pure and the earth grade is more than 90 percent, and the heavenly grade elixir does not contain any impurities.

The spirit-level elixir is beyond the application of the elixir itself, producing a trace of spirituality, which can be transformed into various substances. For a spirit-grade elixir, any grade of elixir has a chance to transform from it, but there are too many impossibilities here, so no one knows how to use it.

Generally, when refining the earth-grade pill, some visions of heaven and earth will appear after the refining is successful, and the pill itself will also exude a faint pill, and after the pill is refined, the vision of heaven and earth is more obvious, and the pill itself is also wrapped in a thick mist, which is rather than dispersed, but it is easy to distinguish.

"Yes, there are many functions in this refining room, and there is much more to it than you see, but the rest is up to you to explore. The stele spirit looked at Xiang Tian with an excited look on his face, and said in a deep voice.

"Well, that's no problem, but I have a question, when you were refining these things just now, you used up one-tenth of the bubbles in this room, what if these bubbles are used up?" Xiang Tian seemed to sound something, and said with a painful face.

"You don't have to worry about this, in the current refining room, about a hundred of these bubbles can be generated every hour, which is 1,200 a day, so don't worry about its consumption. The stele spirit looked at the room and said with a nonchalant expression.

Hearing this, Xiang Tian secretly breathed a sigh of relief, it seemed that his worries were superfluous, if this situation continued, then the problem of cultivation resources in the early stage would be solved.

"Well, alright, I've finished what I need to say, and the rest is up to you. After the stele spirit finished speaking, he didn't wait for Xiang Tian to react, only to see him immediately dodge and disappear into the room.

"I'm going! I'm going too fast. Xiang Tian glanced at the direction in which the stele spirit disappeared, and couldn't help but sigh.

"If nothing else, I'll show up when you're promoted to the foundation building period, and at that time, I'll tell you some of the secrets of this town's boundary monument, and I hope you won't let me down. An ethereal voice quietly reached Xiang Tian's ears, and the latter was shocked when he heard this, but he stopped speaking.

As long as I reach the foundation building period, will I be qualified to know the secret of the town boundary monument? Xiang Tian closed his eyes slightly, but he reviewed all the things of the day again.

The stele spirit has been gone for a long time, and Xiang Tian didn't stay long after opening his eyes, anyway, this bubble won't disappear, so it doesn't matter if he just leaves it like this.

Out of this refining room, Xiang Tian walked all the way to the square of the town boundary monument, looked at the four big characters with "Holy Cultivation Pupil" written on the stone slab in the field, and was silent for a long time......

The next day, Xiang Tian first washed up and put some homemade incense on his body, and then went to pay homage to the Netherworld Ancestor.

Traveling all the way, in less than an hour, Xiang Tian arrived in front of the ancestor's palace. When the gatekeeper saw Xiang Tian coming, he stepped forward and asked, "Who are you, and what is the important matter of coming to my Netherworld Lord's Palace?" ”

"On the next day, at the invitation of Liu Hui's predecessors, I came to visit. Xiang Tian returned the salute slightly and said with a smile.

When the gatekeepers heard Liu Hui's name, they didn't look as nervous as before, and told Xiang Tian to wait here, and one of them went to invite Liu Hui.

In less than a stick of incense, Liu Hui came to Xiang Tian in a hurry, and when Liu Hui saw Xiang Tian, he just said "Follow me" and pulled Xiang Tian towards the side hall of the Netherworld.

When he arrived at the side hall, Xiang Tian was arranged by Liu Hui to wait on the side, and the latter asked the ancestor to go. After a while, Liu Hui came out to inform Xiang Tian that he could go to see the ancestor.

"Forget it, you should have to face it yourself anyway, you can't always run. Xiang Tian took a deep breath, secretly cheered himself up, and walked straight to the main hall.

After coming to the main hall, I saw a black-robed ancestor sitting in the middle of the main hall, described as withered, his eyes slightly closed, but his complexion was extremely gloomy, needless to say, this is the Netherworld Ancestor of the Netherworld Cave. Xiang Tian looked at the appearance of the Netherworld Ancestor, and it was completely conceivable that the latter must have been a ruthless character when he was young.

Xiang Tian didn't dare to slack off at all, and quickly stepped forward to pay respects: "Disciple Xiang Tian, I have seen the ancestor, I wish the ancestor an early achievement of immortal infancy, and longevity and heaven." ”

"Get up. After the ancestor heard Xiang Tian Xiang Tian's voice, he replied flatly.

"Xie Lao Zu. Xiang Tian frowned, and said in his heart that this Ancestral City Mansion was extremely deep, but he couldn't play tricks in front of him. After thanking him, he stood up and said no more.

"Xiang Tian, you actually dared to kill my personal disciple this time, it's really bold. But at this moment, the Netherworld Ancestor's voice was cold, and he shouted loudly.

"The ancestor forgave the sin, and the disciple was forced to kill the killer. Xiang Tian lowered his head and knelt down again with a pop. "The ants are still stealing, how can the disciple sit still and wait to die, then Yin Yun is pressing step by step, the disciple has made this decision, but he has no intention of offending the ancestor Tianwei, and begging the ancestor to forgive him. ”

The Netherworld Ancestor opened his eyes at this time, glanced at Xiang Tian, and said, "I have already heard about this incident from Liu Hui, and Yin Yun is also to blame, and he can't blame others. If I kill you because of this, I'm afraid even the outer disciples will secretly be unconvinced, right?"

Xiang Tian lowered his head, but his heart was spinning rapidly, fighting with the great god in front of him, he must deal with it carefully, if he is too cowardly, the other party must think that he can't get on the stage; if he is too tough, then the other party must think that he is a thorn in the head and get rid of himself.

After thinking about this, Xiang Tian's heart turned, and he immediately straightened up, and said without humility or arrogance: "The ancestor said that he laughed, the ancestor's magic power is boundless, and the people's desire is wanted, how can anyone be dissatisfied? And although Yin Yun is a disciple of the ancestor, his attitude is arrogant and he does not know the general situation, and the disciple is afraid that he will ruin the reputation of the ancestor in the future, so he ......"

Speaking of this, Xiang Tian stopped talking. The other party is an old monster who has lived for hundreds of years, and it is strange that he doesn't know what he means.

Sure enough, I saw the ancestor nodding slightly, and Liu Hui next to him was also smiling, it seemed that he had passed this level.

"Sharp teeth, but there is some ability. Xiang Tian, that Yin Yun is to blame, and you can't blame you if you kill him now. However, he is also a personal disciple of this seat, and if I don't say anything, it will be detrimental to my reputation outside. Well, let me ask you, would you like to bow down to this seat and take Yin Yun's place?" said the Netherworld Ancestor in a soothing tone.

"Thank you to the ancestor for the fulfillment, the disciple will definitely live up to the ancestor's expectations. Xiang Tian was stunned for a moment, and then overjoyed, he didn't expect that this Netherworld Ancestor not only forgave him, but also really let him take Yin Yun's place and become the fourth personal disciple by the ancestor's side.
