The Spirit-Rejuvenating Pill is a pill used by real immortal cultivators. It cannot be refined with ordinary fire like the Huanglong Pill. Refining it requires real fire or earth fire. True fire is transformed by the mana in the body of monks above the foundation establishment. This

The method is naturally impossible for Xiao Yu.

So, he naturally thought of earth fire. Although earth fire is not as usable anytime and anywhere as real fire, it is more durable and stable. It is the best flame for refining elixirs and magic weapons, and it is also relatively simple to control. For low-level immortal cultivators,

It can also be easily controlled by the user.

The Giant Sword Sect naturally has such an important resource like earth fire. Before, Xiao Yu had already inquired about its location from the disciples in the sect.

It is understood that when the sect was first built, the founder of the sect used great magic to gather and pull out the earth fire from under the mountains, and removed the poison of the earth fire before it could be used.

After a while of pouring incense, Xiao Yu stopped in front of a main hall and looked up. On the plaque were clearly engraved three large black characters of "Earth Fire Hall"!

After Xiao Yu thought for a while in front of the main hall, he raised his legs and walked inward.

As soon as he entered the hall, Xiao Yu saw several disciples from the eleventh and second levels of qi training registering something at the table, looking very busy!

Xiao Yu took a few steps forward, cupped his fists towards one of the young monks and said, "Junior brother, I want to rent an earth fire room to make alchemy. Is there any free earth fire room?"

When the young monk saw that Xiao Yu wanted to rent the underground fire room, his face lit up, he clasped his fists and said:

"This senior brother wants to rent an underground fire room! Of course there are vacancies. Is this your first time here, senior brother? Please allow me to introduce you to him first.

The underground fire chambers here are divided into three levels: upper, middle and lower. The upper-grade underground fire chambers have the strongest and most stable flames, followed by the medium ones and the lowest ones. But even the lower-grade underground fire chambers are enough.

The difference between supporting elixir refining and weapon refining is that the stability may be slightly worse. Which level of underground fire chamber do you want to rent, senior brother?"

Xiao Yu was stunned after hearing this. Before he came here, he really didn't know that there were several levels of earth fire chambers. He felt that it was his first time making alchemy, and he had never been exposed to earth fire, so he should choose a superior one.

is more appropriate.

Xiao Yu's thoughts changed quickly and he had already made a decision. He said to the young monk: "Junior brother, I'd better choose a superior one!"

When the young monk saw that Xiao Yu had chosen a superior one, he was even more happy. They, the guarding disciples, could get some commission from it, so he said: "Three spiritual stones for two days for the superior Earth Fire Chamber!".

Xiao Yu was shocked after hearing this. He asked for three spiritual stones in two days. The rent was too expensive. It was just a naked robbery! People who don't have any wealth or confidence in their craftsmanship really don't dare to take it easy.

If you come here, you may lose all your money if you are not careful.

"What about the medium one?" So he asked again.

"The average one needs a spiritual stone for one day." The smile on the young man's face dropped slightly.

Xiao Yu thought for a while, but still took out fifteen spiritual stones with a pained look on his face, and said: "Junior brother, I don't know how long it will take for the time being, so I'll just hand it in for ten days, and then I'll get back more or less."

,OK?"

The young monk seemed to encounter this situation often, so he readily agreed, then handed Xiao Yu a piece of raft and said:

"Senior Brother, this is the prohibition token in the Earth Fire Room No. 20. The prohibition in the Earth Fire Room is very powerful. If the prohibition is turned on inside, even the monks in the Dan Formation Stage will not be able to break through it in a short time. This

There are also instructions for using Earth Fire on the token, please take a closer look after you enter the Earth Fire Room!".

Xiao Yu thanked the young monk and walked into the main hall.

There was a passage inside the hall that led to the inside of the mountain. After some tea time, Xiao Yu came to a huge underground space.

What he saw were rooms covered with boulders, with numbers on them. He looked at both sides, turned and walked towards a passage on the left until he saw a sign with the number 20 on the wall.

, then he stopped and stood still.

After looking at it for a while, he waved the wooden sign in his hand in front of the huge stone gate, and suddenly the huge stone gate slowly opened with a "bang".

Xiao Yu raised his legs and walked towards the door. After entering the door, he saw layers of gray-white stone steps. Xiao Yu walked down the stone steps layer by layer. After walking down about ten feet, a five-year-old boy appeared.

Here comes the six-foot-wide stone chamber!

In the middle of the stone room stands a platform five or six feet high. There are eight thick pillars around the platform, and a three-foot-sized crimson dragon head is cast on each pillar. The dragon's mouth is pointed at the platform, with its teeth and claws very open.

vivid!

There is a yellow futon placed not far away from one side of the stone room, which should be used for meditation by those who refine alchemy and weapons.

Xiao Yu couldn't help but marvel at the layout in the ground fire room!

After watching it for a while, he sat cross-legged on the garden, took the wooden sign in his hand and looked at it!

There are many formation patterns engraved on the wooden sign. Xiao Yu has never learned any formations, so he knows nothing about them. Xiao Yu secretly thought that he must learn the formations carefully when he has the opportunity to build a foundation!

Xiao Yu stopped his thoughts, his consciousness entered the token, and he immediately saw some words.

What was recorded above was exactly how to use the earth fire. Xiao Yu read it carefully!

After a long time, Xiao Yu let out a breath, then thought for a moment, and then struck the red dragon head on the stone wall with a pinch of magic.

After the spell was driven into the dragon's head, a stream of red flames suddenly spewed out from the dragon's mouth and gathered on the stage. It seems that the alchemy furnace was placed on top of the stage to be heated by the ground fire!

Then Xiao Yu took out the silver cauldron and fired a spell. The small cauldron flew to the top of the stage and suddenly became three feet in size. Then he fired a spell at three or seven other dragon heads.

Immediately, eight red flames heated up the silver wire cauldron, and the silver wire cauldron also slowly rotated in the flames.

Xiao Yu added some spring water into the cauldron. After the silver-wire cauldron reached a certain temperature, he took out small medicine bottles one by one from the storage bag and placed them in front of him. Feeling that it was almost enough, he filled the bottles in a certain order.

Add the medicine to the cauldron.

An hour later, the sound of "chuff" and "chuck" came from the alchemy furnace. Xiao Yu sighed softly and started refining it again!

Three days later, Xiao Yu looked at the dregs of medicine in front of him with a wry smile. He had consumed more than half of the elixir and failed even once!

After calming down, Jin Yu began to meditate to restore his mana!

A few hours later, Xiao Yu opened his eyes and cast a spell on the red dragon's head. Immediately, red flames spewed out from the mouth of the dragon's head and rolled under the alchemy cauldron!

He once again put different elixirs into the alchemy cauldron, and from time to time he added some magic spells into it.

An hour later, a faint fragrance emanated from the alchemy cauldron. Xiao Yu was overjoyed and quickly fired a series of spells into the alchemy cauldron.

After a moment, Xiao Yu shouted "Get up!", and the lid of the alchemy tripod rose into the sky! Then it fell gently to the ground.

Xiao Yu couldn't wait to walk to the alchemy cauldron to observe. He saw seven or eight thumb-sized white elixirs lying quietly inside the cauldron, and a scent of medicine filled his nostrils!

Xiao Yu took out a jade bottle with a smile on his face. After pinching the elixir with one hand, he pointed at the mouth of the jade bottle and shouted "Put it away!"

I saw seven or eight white elixirs floating slowly in the elixir furnace, and after two slight rotations, they suddenly lined up in a row and sank into the jade bottle.

Xiao Yu smiled and put the jade bottle into his storage bag, then sat cross-legged on the futon and meditated again to restore his mana.

Eight days flew by!

At this time, Xiao Yu was sitting cross-legged and looking at the three jade bottles in front of him, with a satisfied smile on his face!

In the subsequent refining process, he successfully refined two more batches of spirit-reviving elixirs. With these more than twenty elixirs, he should be able to support himself for use in the forbidden area.

After touching his chin and thinking for a moment, he shook his hand on the jade bottle and the three bottles of elixir disappeared. Then he stood up and walked towards the stone gate!

After walking up the stone steps for another ten feet, Xiao Yu saw that the huge stone door was still tightly closed.

He waved the wooden sign in his hand in front of the stone gate, and the stone gate slowly opened with a "rumbling" sound!

After Xiao Yu went out, the stone door closed on its own.

After Xiao Yu only glanced briefly, he walked out with a slightly raised corner of his mouth!

When he arrived at the registration office, the young monk was still recording something. Xiao Yu held his fist towards him and said, "Junior brother, I have finished refining the elixir, and now I will return the token." After saying this, he handed the wooden sign in his hand to the young man.

The monk's hands.

The young monk was stunned for a moment, and after seeing Xiao Yu's face clearly, he said loudly: "It turns out to be Senior Brother! Judging from Senior Brother's expression, the alchemy must have been going smoothly, right? These are the three spiritual stones I've been looking for for you. Senior Brother, please take them!"

"It couldn't have gone so smoothly. I lost money on the alchemy this time," Xiao Yu said modestly.

When the young man heard this, he looked like I believe you.
Chapter completed!
