Qin Shuang's cultivation does not use immortal crystals, and the immortal crystals earned are enough for Yuan Tong to cultivate. As for the elixir refined by the Southern Stratus Cloud and the White Mist, after being sold, it was handed over to Qin Shuang for sixty percent, and the two of them could keep forty percent.

In these three months, Qin Shuang has been able to refine the Danwen-level elixir, but he has not yet refined the Danwu-level elixir. She knew that the reason why she couldn't refine the pill of the Dan Mist level was because the level of the pill she refined was different, and the pill that was suitable for the Earth Immortal Stage required the materials was no longer so ordinary.

However, Qin Shuang did not start selling the elixir that was suitable for the cultivation of the Earth Immortal Stage cultivators, and she did not want to sell it until the pills suitable for the cultivation of the Earth Immortal Stage were not allowed to be refined in the Demon Suppression Tower.

Because once it starts to be sold, she needs to keep supplying, without the time flow rate of the Demon Suppression Tower, providing so many elixirs every day, it's too much of a waste of time, does she still want to cultivate?

However, Qin Shuang bought a large amount of seeds from Xiangjiacheng and planted them in the Demon Town Tower. However, it takes more than a thousand years of medicinal materials to be able to refine the Danwu Danyun level pill, and three months in the Demon Suppression Tower is only about three hundred years, and in order to improve the alchemy realm, Qin Shuang also keeps picking, using medicinal materials that are about a hundred years old, how can he refine that level of pills?

Qin Shuang walked into the alchemy room, and with a thought, he entered the Demon Suppression Tower.

Strolling to the medicine garden, Qin Shuang would enter the Demon Town Tower once a day, pick the grass seeds of mature herbs, and plant them in the medicine garden, so the herbs in Tianlin Star were basically planted by her, except for some extremely precious herbs.

Looking at these herbs, Qin Shuang did not pick them. She had to wait for these herbs to be thousands of years old before picking and refining them. After tidying up the medicine garden, Qin Shuang came to the valley built by Xiao Huang.

Standing at the mouth of the valley, I saw Xiao Huang lying on the ground, exhaling and breathing, the fairy clouds spitting out, and the fairy rhyme was swirling. The most precious herbs are cultivated here.

Like the herbs for refining the Realm Breaking Pill are all planted here, the seeds that Qin Shuang planted at the beginning, only the herbs of the Earth Immortal Breaking Realm Pill are alive, and the herbs above the Heavenly Immortal Breaking Realm Pill are all dead, they have not sprouted at all, and they are directly rotten in the ground.

Qin Shuang knew that this was because the Heavenly Dao in the Demon Suppression Tower was incomplete, so he didn't plant it anymore, but just concentrated on serving the seeds of those Earth Immortal Breaking Realm Pills.

Three months in the outside world, nearly three hundred years in the Demon Suppression Tower.

For nearly 300 years, Qinshuang has continued to plant mature grass seeds, and now those herbs have become patches. Today she was going to pick some herbs and start trying to refine the Earth Immortal Realm Breaking Pill.

After picking some centuries-old herbs, Qin Shuang left the Demon Town Tower. Instead of taking out the Whirlwind Fruit sent to the king, he took out the Whirlwind Fruit he owned and began to refine it.

About two quarters of an hour later.

"Bang ......"

There was a soft sound in the alchemy furnace, Qin Shuang hurriedly opened the lid of the alchemy furnace, looked inside, and saw that the medicinal liquid in the alchemy furnace began to condense towards the middle, first forming the shape of a tree root, and then the root began to grow, giving birth to the main trunk, giving birth to branches, and giving birth to leaves.

Qin Shuang's face was a little bit.

"The pill liquid becomes a tree, and it seems that the materials of a hundred years can also be refined to produce the Earth Immortal Breaking Realm Pill. ”

About sixteen breaths had passed, and a small tree had already formed in the alchemy furnace, and Qin Shuang took out a whirlwind fruit that he owned and put it into the alchemy furnace.

The whirlwind fruit landed on the main trunk of the small tree in the alchemy furnace, and when he saw the main trunk squirming, he devoured the whirlwind fruit into it.

Qin's eyes were staring at the whirlwind fruit, and his hands began to punch out one pill after another, and as the pill tricks entered, the wind whirlwind fruit in the trunk began to shrink, and the energy in the wind whirlwind fruit was extracted by the small tree.

On the branches of the small tree, flower bones slowly grew.

Qin Shuang's Dan Jue was faster, his hands made a series of afterimages in the air, and the power of divine consciousness was also projected from the center of his eyebrows, and he constructed a series of Dan seals and fell into the alchemy furnace.

One!

Two!

Three!

Thirty-six.

Thirty-six flower buds sprouted on the small tree, and the pill recipe played by Qin Shuang became more and more urgent, the divine consciousness from the center of the eyebrows faintly shone brightly, and the condensed runes were sprinkled in the alchemy furnace like Yingluo.

Qin Shuang's face gradually showed a relaxed smile, and there was also anticipation.

"Buzz ......"

Suddenly, the alchemy furnace shook, and the thirty-six flower buds had begun to bloom, but at this time, the pill trick played by Qin Shuang had a slight incongruity, and the thirty-six flower buds shrank rapidly.

"Bang!"

Then there was a bang, and the small tree exploded, and a puff of smoke rushed out of the entire alchemy furnace.

"Hoo ......"

Qin Shuang let out a long breath.

"Just a little bit!"

Qin Shuang cleaned up the alchemy furnace, cleaning it again and again, thinking about what was wrong with him. Then it was refined again.

This time she did it perfectly, but she still failed. Qin Shuang closed her eyes, and the process of alchemy flashed in her mind in detail.

"It should be that the effect of the whirlwind fruit is not enough. ”

Qin Shuang took out a copy of the materials of the Earth Immortal Breaking Realm Pill that Xiang Wang had given her, and began refining the Earth Immortal Breaking Realm Pill.

About three quarters of an hour later, the Earth Immortal Breaking Realm Pill succeeded, although it did not reach the rate of thirty-six pills, only twelve were refined, and they were all of the highest grade, not a single of them were of the best grade. However, this proves that the previous speculation of the piano pair was correct.

The previous refining was unsuccessful, and the main problem was that the effect of the Wind Whirlwind Fruit was not enough, after all, it was only a spirit fruit, not an immortal fruit.

However, is it possible to improve the pill prescription by adjusting the dosage of other auxiliary medicines, and successfully refine the Earth Immortal Breaking Realm Pill?

Qin Shuang fell into the deduction, and even forgot to come to cultivate, every day is the deduction, enter the demon tower to pick herbs, and then come out for alchemy.

This situation lasted for a month, and nearly a hundred years passed in the Demon Suppression Tower. When Qin Shuang was alchemy again, everything suddenly became much smoother.

Inside the alchemy furnace.

The small tree grew rapidly, thirty-six flower buds bloomed, and thirty-six fruits subsequently bore fruit.

The silk immortal yuan power swirled in the alchemy furnace, nourishing the thirty-six fruits, and from the thirty-six fruits, the danxiang came out.

"Bang Bang Bang ......"

Thirty-six fruits fell in turn in the alchemy furnace, and the small tree had withered and dissipated.

Qin Shuang took out the thirty-six fruits from the alchemy furnace, and these thirty-six fruits were the Earth Immortal Breaking Realm Pill. His gaze swept over the thirty-six fruits, and Qin Shuang's heart was a little disappointed, thirty of them were all waste pills, only six were Cheng Dans, and they were all lower grade pills.

Qin Shuang sat there and pondered.
