Sleeping for a second increases my blood energy. I become the strongest sky-swallowing snake

Yes.

Elixir!

Spirit Replenishing Pill!

Perhaps the solution is this.

The reasoning is simple.

The system wouldn't give him a pill formula for no reason.

Refer to the Transformation Grass.

The answer is on the surface.

"Now, I'll just wait for Ling Yunzi to refine the pill and verify if my thinking is correct," Xu Chengxian thought to himself, feeling confident after a thorough analysis.

He felt he shouldn't be wrong.

Now, all he had to do was wait patiently for the result.

"Ling Yunzi said the pill formula I gave him was different from what he knew and needed consideration. I wonder how his consideration is going. Hmm?"

Buzz—Buzz—

Just as he was hesitating whether to send a message to check on the situation.

Suddenly, a faint fluctuation of spiritual energy startled him.

Paying a little attention, he discerned the aura and the direction it came from.

Near the spiritual vein where the Bai mansion was located.

"Let me see."

Now that he had confirmed it was within his own territory, Xu Chengxian unhesitatingly extended his divine sense to investigate.

Upon approaching, he roughly understood what caused the spiritual energy fluctuation.

It turned out Ling Yunzi was about to open the furnace and complete the pill he was refining.

Of course, it wasn't the Spirit Replenishing Pill being refined.

But the Transformation Pill.

Hesitating for a moment, he still extended his divine sense towards the mountain peak.

After moving into the new cave dwelling, this place had become Ling Yunzi's pill refining room.

Whether refining pills or forging weapons, there was an unavoidable risk of the furnace exploding.

Therefore, a special defensive formation had to be set up in the refining location.

This was to prevent interference from outsiders and also to prevent the furnace explosion from causing greater damage.

They didn't have those conditions now.

Ling Yunzi simply chose the mountain peak as the place for refining pills.

He only slightly arranged some means with the effect of blocking and warning around it.

—A few well-behaved, but very loud little demons.

Then, by stopping them outside and preventing them from entering at will, everything would be fine.

Mount Luyang was the base of General Yu, this demon general.

For the demons living here, he was the greatest protective force.

Then there were Ling Xiao and Xu Chengxian.

If someone could ignore all of these and directly rush to Ling Yunzi's pill refining location, then he wouldn't need to think about how to resist.

Turning around and running away would be the best strategy.

Although it would damage the demeanor of a Dao Lord, he was now just a great demon.

He would only be losing the face of the demon Ling Yunzi, what did it have to do with the human Ling Yunzi, Dao Lord?

"Tsk."

This wasn't Ling Yunzi's first time refining pills, so it wasn't Xu Chengxian's first time seeing this thing either.

But when he thought about how this thing was just a small black gold cauldron before it was infused with mana, he couldn't help but take a few more glances.

The pill furnace in front of him didn't have too many gorgeous decorations on its exterior, and there was a faint trace of the passage of time, revealing a sense of tranquility that didn't attract dust amid the mottled marks.

The body of the furnace was round and heavy, and the three legs at the bottom stood firmly, supporting the entire furnace body. Under the burning of the raging furnace fire, it seemed to be covered with a layer of red light.

And now he still remembered the scene where, with a low and long buzzing sound, the small cauldron gradually expanded in his astonished gaze and transformed into a large cauldron, standing in front of him.

The feeling of seeing it with his own eyes was really quite wonderful.

Ling Yunzi said this pill furnace was crudely crafted, with only a few simple or even rudimentary formations embedded in it.

Unlike some human pill furnaces, which had formations suitable for refining various pills to assist in controlling the heat.

But its advantage was that it was entirely cast from pure black gold.

When the external pill fire was lit, as the flames leaped, the fire would quickly be transmitted to the inside of the pill furnace.

Moreover, the biggest advantage of black gold was that it could isolate part of the explosive aura in the pill fire.

Perhaps this was the reason why it appeared in the territory of the demons.

Also, although the refining technique was crude, it didn't seem like the person who refined the pill furnace had poor weapon forging skills, but rather seemed to be doing it on purpose.

Because above the furnace mouth, there were circles of special runes.

When refining pills, one only needed to perform hand seals and release mana in a few places to activate the array runes.

The activated rune array could guide the surrounding heaven and earth spiritual energy to slowly gather, forming visible spiritual energy vortexes that continuously poured into the furnace.

Providing spiritual energy for pill refining.

Although the introduced spiritual energy was scarce and slow, this was precisely convenient for the alchemist to control.

"No wonder Ling Yunzi regrets not having a furnace lid."

Out of curiosity, Xu Chengxian's divine sense floated into the air and looked down at the pill furnace. He could indeed see wisps of spiritual energy turning into a faint white mist, obscuring the furnace mouth of the pill furnace.

Making it impossible to see the situation inside the pill furnace completely.

This pill furnace that could attract spiritual energy was quite interesting.

It made people couldn't help but want to know what it would be like if it had a furnace lid.

"But if it was a complete furnace, we probably wouldn't have a chance to find it by chance," Sometimes he couldn't help but suspect whether Ling Xiao and Ling Yunzi, these two guys, had brought bad luck to his fortune.

The empress and Dao Lord who were in high positions, must have committed many sins in their previous lives.

Compared to them, he was just a pure and innocent baby.

In his previous life, he rarely killed living beings except for flies, mosquitoes, and cockroaches.

Otherwise, as a transmigrator, he should be finding a small treasure every three steps and a big treasure every five steps.

Unlike now, he hadn't seen a single heavenly treasure.

The pill furnace he found by chance was so simple and unadorned.

At most, it was of the high-grade magic artifact level, just a little short of reaching the spiritual artifact grade.

But fortunately, the quality of the pill furnace wasn't the key to determining whether a pill could be successfully refined.

At least the pills that Ling Yunzi was going to refine didn't require spiritual artifact or treasure artifact pill furnaces.

Buzz—Buzz—

Another wave of spiritual energy vibration.

The spiritual flames tumbled and leaped in the furnace, as if they had intelligence, accurately wrapping each medicinal material and performing the most meticulous extraction and fusion.

Ling Yunzi was wearing a plain white robe, his face was as calm as water, his eyes were tightly closed, one hand formed a seal, and faint rays of light overflowed from his fingertips from time to time.

The light shot into the furnace.

One hand pinched his fingers, guiding the pill fire, echoing each other remotely.

From time to time, he also had to pinch a flame and send it into the pill furnace.

Xu Chengxian didn't understand pill refining, but he could roughly feel that it was reaching the end of pill formation.

All the spiritual medicines and spiritual materials had been put into the pill furnace according to the sequence method.

Then at this time, he should be controlling the heat of the pill fire to carry out the final fusion of medicinal power.

Having secretly watched the pill refining process several times, he could still see this.

Moreover, Ling Yunzi had already practiced the Transformation Pill once within this month.

It was only half a month ago.

It had to be said that their spiritual plant bank plan was progressing very smoothly.

The spiritual materials for the Transformation Pill were collected within a few days.

"I wonder how much is still lacking for the spiritual materials of the Spirit Replenishing Pill," Xu Chengxian thought to himself.

When he woke up last time, he asked Ling Xiao, it seemed like there were still two kinds of spiritual plants and one kind of spiritual material missing.

Another half a month had passed, should they be able to collect them all?

At this time, a medicinal fragrance emerged from the inside of the pill furnace.

The fragrance was fresh and elegant, containing vigorous vitality, as if it could wash away the dust in people's hearts and make people's spirits invigorated.

The spiritual power fluctuations in the surrounding air were also a little larger.

After a few breaths.

Finally, in a clear and melodious buzzing sound, the flames in the furnace slowly extinguished.

A more intense, more pure fragrance instantly spread out.

"Is the pill about to be formed?"
