At this time, Xiao Yu's soul body had entered the mysterious space. When he came to a corner, Xiao Yu looked at the dozens of jade boxes in front of him, and couldn't help but feel excited.

These jade boxes contained all the elixirs he had picked from the forbidden areas. Some were mature and could be used directly to make elixirs, and some were immature elixir seedlings.

Xiao Yu picked the elixirs himself and obtained them by killing others, and unknowingly he added up to so much. When these elixirs were taken out, even the golden elixir monks would fight over them and grab them.

What he needs to do next is to ripen the three-flavored elixir, which is the main component of the Foundation-Building Pill, as quickly as possible so that he can start making the elixir.

In the past three years of training, Xiao Yu had already matured thirty-one auxiliary medicines into enough quantity to refine hundreds of pills.

So this time he only needs to ripen the three main herbs, and he also has several strains of the three mature elixirs. The remaining amount of ripening will not take long.

With this thought in mind, after looking at other spare items, Xiao Yu exited the space and began the process of ripening the elixir and drawing talismans every day.

In this way, three months passed quickly day by day.

During this period, Xiao Yu learned the secret art of blood refining obtained in the forbidden land, and then used the mysterious heavenly book to optimize it into a new secret art of blood refining. After mastering the new secret art, he waited for the foundation to be established.

The magic weapon was blood-refined.

On this day, after dealing with the routine inspection of the medicine garden by the patrol deacon, Xiao Yu brought all the ripening elixirs and came to the Earth Fire Palace!

Those in charge of reception and registration in the Earth Fire Hall were still the same disciples a few months ago.

One of the young men had sharp eyes and saw Xiao Yu at a glance and recognized him. Then he quickly came up to him and said enthusiastically:

"Hello, senior brother! You are here again. Are you still making alchemy this time?"

Xiao Yu smiled and said: "Yes, I have saved some materials this time, and I plan to open a furnace to see if I can get some results. By the way, are the top-grade underground fire chambers still available?"

"Yes, yes! Wait a minute, senior brother. For alchemy, you must choose a high-grade earth fire chamber. Especially for novices, it will be of great help. I believe that you, senior brother, have experienced the wonderful use of this kind of earth fire chamber last time.

"

While looking for the token, the young man kept talking:

"Well, I found it. Currently, the only high-grade underground fire room left is No. 23. Senior brother, this is the token, please keep it!"

Xiao Yu took the token with a smile, paid the deposit, thanked him, and walked towards a passage in the hall.

After a long walk, Xiao Yu came to a huge underground space.

After passing through the rooms covered with boulders, he came to the outside of a room with the number 23 hanging on the wall.

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 "rumbling" sound.

Xiao Yu raised his legs and walked towards the huge stone door. After entering the door, there were layers of blue stone steps. He walked down the stone steps layer by layer. After a while, he came to a five or six foot wide door.

In the stone chamber.

There is a three-foot-high stone platform in the middle of the stone chamber. There are eight thick pillars around the platform, and a two-foot-sized red dragon head is cast on each pillar. The dragon's mouth is pointed at the platform, and its teeth are grinning very vividly!

The layout of this underground fire room No. 23 is similar to the layout of No. 20 used last time. It seems that the top grade underground fire rooms are not much different.

Xiao Yu walked to the futon placed on the side of the stone room, sat cross-legged and meditated, recharging his energy.

He sat there for half a day. When he felt that his mental and physical strength were in the best condition, he opened his eyes and stood up, ready to start refining elixirs.

Xiao Yu took out the silver cauldron from his storage bag and cast a levitation spell on it, causing it to stop directly above the stone platform out of thin air.

Then eight red lights were fired at the dragon's head, stimulating the purple earth fire in the dragon's head.

Because no raw materials had been put into the cauldron, Xiao Yu controlled the ground fire to make it very small, only as thick as a silk thread. Then he let the silver wire cauldron begin to slowly rotate out of thin air under the burning of eight lines of fire.

With the experience of refining the elixir last time, Xiao Yu is obviously much more proficient in controlling the ground fire this time. He can already control the thickness of the fire line and the injection angle accurately.

A quarter of an hour later, the silver tripod was already hot, emitting an astonishing high temperature.

Seeing this, Xiao Yu pointed at the small cauldron, and the lid of the silver-wire cauldron immediately flew up, revealing the mouth of the cauldron.

After turning his right hand, a jade bottle appeared in his hand. The bottle contained a prepared elixir powder in precise quantities.

In order to prevent failure and accumulate experience, Xiao Yu had already divided all the elixirs into one by one according to the proportion before coming here. He only refined one piece at a time, which was enough for him to refine.

A hundred times.

I believe that among hundreds of continuous refinings, he will always be able to succeed a few times!

One month after Xiao Yu returned to the sect from the forbidden area, the sect sent him rewards, including a foundation-building pill and hundreds of spiritual stones.

This time, he only needs to succeed two or three times to get three foundation-building pills. With his qualifications of three spiritual roots, he should be able to successfully build the foundation with three or four foundation-building pills.

.

Controlling the jade bottle, Xiao Yu poured all the powder in the bottle into the silver tripod, then took out another bottle from the storage bag and continued to repeat the same action.

Next, Xiao Yu poured all the dozens of elixir powders he needed into the silver cauldron, and finally put the lid back on.

The purple fire spewed out by the eight dragons changed from thin to thick under Xiao Yu's control, while the speed of the silver tripod's rotation gradually slowed down and began to tremble slightly in the flames.

As time passed little by little, the slightest hint of medicinal fragrance emitted from the small cauldron, which made people feel refreshed.

However, Xiao Yu knew that it was still very early for the elixir to be formed at this time, and it was necessary to use more violent earth fire to condense the elixir instantly, so that the elixir could be formed.

Thinking of this, Xiao Yu controlled the earth fire to increase its power. Soon, the purple fire became thicker and more dazzling, even reaching the point of being as thick as the mouth of a bowl, covering the entire silver cauldron.

It becomes more and more intense.

Xiao Yu knew that this was the medicine powder starting to condense into elixirs, so he became more and more concerned about it.

But just a moment later, a muffled cracking sound came from the cauldron. Although the sound was not loud, it still made Xiao Yu's heart sink and his face became a little ugly.

Sighing, he stopped burning the ground. Then with a move of his hand, he opened the lid of the still hot cauldron and stretched his head to take a look.

The medicinal powder in the cauldron did not condense into pills, only a few pieces of broken light blue solid.

Shaking his head, Xiao Yu took out a jade box and placed it on the ground. Then he controlled the silver tripod and turned it over, pouring the waste elixirs into the box and storing them away.

Although these were broken waste elixirs, he still kept them properly. Maybe they would be used somewhere in the future.

After doing all this, Xiao Yu returned to the futon and meditated. He didn't start refining the elixir again until the silver cauldron had completely cooled down.

The same steps, the same raw material powder, the same fire control method, but this time it still failed.

This time Xiao Yu had no expression on his face. After adjusting his condition, he silently started the next round...

After refining the elixir twenty times, the elixir was successfully condensed, but failed when opening the furnace to take the elixir...

It was not until forty times that Xiao Yu finally succeeded in refining a Foundation Building Pill.

This foundation-building pill is exactly the same as the one awarded by the sect, which greatly boosts Xiao Yu's spirit!

After this successful experience, Xiao Yu's chances of condensing pills immediately increased. One of the four refining attempts was successful. For opening the furnace, there was also nearly half a chance of success.
