Knowing that it would be very dangerous for Su Che to go out of the mountain gate, several ancestors couldn't stop him. This is because the growth of a cultivator needs to be trained and sharpened, and it cannot be just an ornamental thing like a flower in a greenhouse.

If all Su Che's affairs were done by the sect or the ancestors, then no matter how good the seedlings were, they would grow into waste.

Su Che himself understands this truth, so what he should do will never be done by others.

In the cultivation cave at the top of the Xuanhell Peak, Su Che had been in retreat for three days, and he felt that the time had come to start attacking the middle stage of the Golden Pill.

The so-called timing is not only a feeling, but also a kind of self-confidence, and Su Che and Lao Hei even thought of a trick to improve their true element quality.

Compared with the early stage of the Jindan period, the difference between the two is that the true yuan of the middle stage of the Jindan is more condensed and more mellow, just like the difference between the eighth-level spiritual fire and the seventh-level spiritual fire.

To put it bluntly, it is to find a way to raise the grade of one's true element by one level, and the golden pill in the body will naturally change.

First of all, in order to reach the peak state of the early stage of Jindan, cultivation also requires realm perception, the correct way to condense the true element, the opportunity for retreat, luck ......and so on.

The method that Su Che and Lao Hei thought of was to take the unusual path and use the way they burned the true yuan when they were married last time, as well as the piece of Nirvana Divine Wood that they bought in the floating city, to improve the grade of the true yuan by alchemy.

It sounds complicated, but it's actually quite simple!

It took three days to adjust the true element in the body to the peak state of fullness, and today, Su Che is ready to rent soup with Lao Hei.

What is a rented soup?

Or the true yuan in the body was infused into the immortal prison, forming a big crimson crystal ball and falling into Lao Hei's hands.

Lao Hei summoned a treasure Dan furnace, cut off a small piece of the Nirvana Divine Wood and soaked it into the True Yuan, threw it under the Dan Furnace to ignite the eighth-level spiritual fire, and began to boil the True Yuan and the Divine Wood like a negative soup.

The function of the Nirvana Divine Wood is that it can raise the spiritual fire below level 10, so that the grade of the spiritual fire can be increased by one level.

Then, Su Che and Lao Hei then speculated: Logically speaking, it can also improve the true element of the fire system.

Of course, this kind of practice is impossible to achieve in the normal world, because it has been said before that in the normal world, once the true element is separated from the body, it will become invisible and instantly dissipate, and only in the immortal prison will it condense into a crystal-like substantive existence.

Whew......h

The spiritual fire in the furnace was booming, and Lao Hei guarded the Dan furnace, muttering in a low voice: "Master Zhenyuan cooks wood, will the taste be too light, can you add some more ingredients?"

Is this really like burning soup?

"I'm afraid that you put too much salt, so salty that I can only change to the water system exercises....... Su Che replied angrily.

Zhenyuan boils wood, once this method is said, he will definitely be scolded by others, it is pure nonsense! To be honest, Su Che himself has no bottom in his heart, and he just has the mentality of trying it out. If it really doesn't work, then you can only advance in a conventional way, and whether you can be successful this time is not certain.

"No, master. Lao Hei said in a serious tone: "Add some good things to it, maybe, you will be able to condense the unique true yuan in the history of cultivation, and when you advance to the middle stage of Jindan, you will be able to comprehend the supreme supernatural power!"

"Imagination is really commendable. Su Che said half-seriously and half-jokingly: "Tell me, what are you going to add to it?"

Generally speaking, during the Jindan period, every time they are promoted, immortal cultivators can comprehend a kind of supernatural power. The early, middle, and late stages add up to three kinds of supernatural powers.

In the early days of the last promotion to Jindan, Su Che comprehended the Great Fire Control Technique, "This promotion will definitely lead to another fire-based supernatural power, so there is also an inexplicable expectation for the whimsical statement of Lao Hei Gangang."

Fooling around and adding ingredients indiscriminately, can it really produce miracles?

"What should I add?" Lao Hei held his head and began to ponder.

Of course, Su Che himself was also using his brains and thinking hard. ,

"How about adding some spawning ichor?" asked the old black.

In the large pot carrying the Black Domain Immortal Lotus, a lotus seed has been planted. The spiritual liquid that can accelerate the growth of lotus seeds, relying on the power of the sect of Tianxuan Sect, can easily be concocted, and now, it can be watered once a week.

According to Yin Luo, twenty years can give birth to a finished immortal lotus.

Lao Hei's idea was that since it was to give birth to spiritual liquid, could he speed up Su Che's cultivation and compress the cultivation process that originally took a thousand years to twenty years to become an immortal .......

It felt like there was some truth, but I didn't expect it to be reprimanded by Su Che.

"Your ass is very smart, you!" Su Che scolded, "I am only twenty-two years old now, and in another twenty years, I will become a thousand-year-old man." You're already perfected in the trick of killing without seeing blood, aren't you?"

"Oh yes!" Lao Hei slapped his head hard: "I want to go wrong! This thing gives birth to years, not cultivation." ”

The master and servant fell into a ...... of thinking again.

The flames in the Dan furnace were churning, and I didn't know when I would be able to put a pot of soup on it.

"Dragon Ball?" After half a sound, Lao Hei had an idea again, and his eyes glanced at the little dragon on the side of Dragon Snake Lake.

"Spare it. Su Che shook his head in his heart.

The little dragon had already woken up and had adapted to the power of the Dragon Ball, and it was impossible for Dang Ran to evolve into a real dragon so quickly, but it was already a mid-level strength of Lan Satin, which was equivalent to a human monk in the middle of the Jindan period.

If its dragon balls are boiled, maybe its bright future will be turned into soup.

"Then, cook me!" said the old black volunteer.

Su Che pondered for a moment, nodded and said, "This can be tried." If it works, if it doesn't work, it will waste a quarter of the true yuan, and you can make it up for it after two days of cultivation.... ”

"Okay, just cook me!"

Old Black grinned.

It wasn't really to throw Lao Hei into the Dan furnace to boil, the master and servant were referring to a strange energy in Lao Hei's body.

Lao Hei is the fusion of the creatures of the three clans of people, demons and demons, and he fused three times before and after, not only fusing the bodies of a total of nine creatures, but even the energy in their bodies was completely fused together.

The demonic power of the human true element demon clan and the temple qi of the heavenly demon fused together to form a very strange and very alternative energy, revealing a primitive and ancient barbaric atmosphere.

It's just because, Lao Hei is a machine spirit, and his body can never come out of the immortal prison, and what kind of effect this energy will have in the normal world has always been a mystery.

So today, Su Che and Lao Hei, two daring researchers, "plan to mix this energy with Su Che's true element, and boil it, I don't know what will happen."

Lao Hei spread out his right claw, the center of the claw was facing upward, and soon a dark gray energy body condensed into shape, and it also turned into an energy ball.

"A feeling of being dirty...... Su Che muttered secretly, "It turns out that your inside is really so dirty." ”

"Of course. Lao Hei smiled proudly: "Otherwise, how can you be worthy of the external ugliness." ”

Syllable!

The Dan furnace was opened, and the dark gray energy ball was thrown into it.

Cook slowly!

Outside the Immortal Prison, Su Che held his cheeks and waited patiently: Inside the Immortal Prison, Lao Hei was holding his chin and guarding the Dan Furnace and was also waiting patiently...

The whole day passed, and there was no movement in the Dan furnace.

The next day was the same.

On the afternoon of the third day, there was finally a reaction!

Coo-goo-goo......-goo

There was a strange sound in the furnace, as if a beast was hiding in it, and a warning roar came out of its throat.

Airplanes.......

The Dan furnace also trembled violently, as if it might burst at any moment.

"Hurry up ......".

Su Che only said one word, and Lao Hei had already reacted, took out the bronze treasure gourd, and hurriedly collected the eighth-level spiritual fire in the Dan furnace.

There is a prisoner of a six-rank alchemist in the immortal prison, "In the past two years, Lao Hei has long read his alchemy experience and memories into his head. Therefore, Lao Hei's alchemy level can almost reach the level of a fifth-grade alchemist. ,

As soon as the spiritual fire was collected, the strong reaction in the Dan furnace slowly calmed down, and for a while, Lao Hei was also quite apprehensive, and he didn't dare to open the Dan furnace.

"What are you afraid of!"

Su Che has never lacked guts, although he can't refine pills, but it is not a problem to use the power of his immortal prison master to lift the lid of a pot that burns soup.

Fraud!

The Dan furnace opened, and a dark red column of gas rose into the sky.

"Ouch, this fire is suffocating. The old black muttered and stepped forward, glanced into the Dan furnace, and then, with a gesture, took out a steaming dark red liquid and suspended it in the air.

Originally, Su Che's true element belonged to a semi-crystalline and translucent crimson color, but now, with the addition of the dark gray body energy of the old black, the color has deepened a lot, but I don't know what kind of changes have been made in the attributes.

"Poisonous? Not poisonous?"

Before figuring out the situation, Su Che would certainly not recklessly take it back into his body.

"Find a substitute for the dead to test it out. ”

As soon as Lao Hei's heart moved, he summoned a certain felony to his eyes.

This person is a disciple of the Xuansha Sect, and was caught by Su Che in the Xiaomi Immortal Realm and put in the Immortal Prison, as a demon monk, there must be a lot of blood on his hands.

"Boss Black Mo. ”

This person nodded and bowed, respectful in front of Lao Hei.

After surviving in the Immortal Prison for more than four years, of course he would often see the cell boss Hei Mo in the first floor of the Immortal Prison."

Lao Hei didn't talk nonsense with him, picked out a drop of dark red liquid, flicked his fingers, and punched it into the prisoner's body.

After a moment, he asked, "Boy, how do you feel?"

"Nothing special. The prisoner shook his head, and he himself was looking inward, and replied, "What Master Heimo has rewarded me with seems to be a drop of extremely high-grade, extremely mellow true yuan, and the inner energy is extremely powerful, and I need a certain amount of time to refine it." ”

This prisoner is also majoring in the fire system, but he is only practicing the Great Perfection Realm of Qi, and he only has true qi in his body, but no true yuan, and it will take at least half a month to refine this drop of mutated true yuan.

"Give it back!"

Old Black held out his palm at him.

"Yes, Boss Black Mo. ”

The prisoner obediently forced the drop of true yuan out of his body and returned it to Lao Hei.

Sou!

Lao Hei sent him back to his place and said to Su Che: "Master, he is fine only during the Qi cultivation period, it seems that this mutated true element is not harmful to the human body." ”

Su Che answered, and he was about to take the dark red mutant true element back into his body...... ，。 ）
