Looking at the night mint with only the last plant left, Qin Deng put it into the storage bag, held a spirit stone in his hand and began to recover his Yuan power.

Half an hour later, Qin Deng opened his eyes, took out the spirit grass and began to purify, this time, he started with the simplest foundation-building grade spirit grass, and then the Jindan-level spirit grass. It only took less than half an hour to purify the foundation-level spirit grass and Jindan-level spirit grass.

When the foundation building grade spirit grass and the golden pill grade spirit grass were purified, Qin Deng began to purify the Nine Hells grass again.

The first time, the Nine Undertures Grass only purified fifty percent of the essence, this time, with the first experience, with the addition of Qin Deng's caution, all his efforts, and finally the essence of the Nine Underworld Grass was purified out of seventy percent.

Qin Deng was very satisfied with this result, he also knew that this Nine Hells Grass was a Yuanying-level spirit grass, and he had not yet been promoted to the Jindan stage, with the Ding Wang Tree Dading, the best fire spirit stone, and his special divine sense, he could only do this step, which was already his limit.

Next, the refining was also successfully completed, and it came to the step of Hedan.

The failure of the refining of the last furnace of the Night Star Pill was because there was a problem in this step of the Hedan, the attributes of the Nine Immortal Grass were extreme, and the level was too much higher than that of other spirit grasses, and it was extremely difficult to follow the Hedan.

Qin Deng took a deep breath, urged the Fire Red Ding King Tree Dading with the power of the Fire Yuan, and began to cautiously look at the Hedan when the flame temperature and state reached the most stable dìng.

Hedan is to adjust yin and yang, and to harmonize with qizheng, so that all kinds of spiritual grass essences are perfectly fused together, giving birth to wonderful changes, so that it has a special effect. This process is extremely important.

Hedan begins, half an hour later. Several other spirit grass essences were perfectly fused together, but the essence of the Nine Spiritual Grass was still distinct from the essence of other spirit grasses, as if water and fire were incompatible.

The reason why the last furnace failed in alchemy was because the Nine Underworld Grass and other spirit grass essences could not be fused for a long time, and Qin Deng finally forcibly used Yuan Force to promote the fusion of the Nine Underworld Grass Essence with other spirit grass essences, and the guide could not be controlled, and finally a furnace of elixir was refined.

This time, Qin Deng was cautious, a little bit of running-in, he didn't dare to be as reckless as last time. Impatient.

Qin Deng slowly let the Nine Immortal Grass Essence get closer to the other Spirit Grass Essence. While recalling a strange Hedan method on the Xuandan record - the Xuandan method.

This spinning pill method is to make all the spirit grass essence rotate quickly, and when the degree of rotation reaches a certain degree, the spirit grass essence that is difficult to fuse will slowly penetrate and slowly become compatible.

However, this spinning pill method requires a wisp of divine consciousness to be integrated into the essence of the spirit grass. Stir slowly to induce. Moreover, the mind should pay close attention to the changes in the essence of the spirit grass. In case of accidents.

This kind of Xuandan method has very high requirements for the divine consciousness and mind. Because the extreme rotation of the spirit grass essence needs to be guided by the divine sense, and the mind needs to be monitored. Once the Spirit Grass Essence rotates, the mind and divine consciousness can't withstand the rotation of the Spirit Grass Essence. It is likely to lead to damage to the consciousness and confusion, and it is easy to go crazy if you are not careful.

After carefully recalling the Xuan Dan Method, Qin Deng poked out a wisp of divine consciousness and entered the spirit grass essence, like a chopstick stirring the water in the bowl, making the spirit grass essence begin to rotate slowly.

When the spirit grass essence slowly rotated, Qin Deng quickly played a complex pill formula, after the pill recipe traction, the moment the yuan force entered the tripod, the degree of rotation of the spirit grass essence became faster, and faster and faster, and finally the spirit grass essence in the tripod became a blurred phantom.

At this time, Qin Deng's divine consciousness was distorted by the extremely rotating spirit grass essence, as if it was constantly being pulled by knots, and the severe pain almost made him scream.

At the same time, Qin Deng, who sank his mind into the spirit grass essence, felt a burst of intense dizziness, feeling like a spinning top, and the whole person was also following the spirit grass essence to rotate rapidly.

The pain of his consciousness, the dizziness of his body and mind, made him want to vomit so much, and his head hurt so much that he almost wanted to hit the wall.

At this time, his ability to be distracted played a very big role, and when he felt that he couldn't stand it anymore, he used the other half's mind, and so on alternately, so that he persevered.

The spirit grass essence in the ding rotated for nearly half an hour before it began to slowly fuse. Feeling the trend of the Nine Hells Grass beginning to merge with the Spirit Grass Essence, Qin Deng's heart in pain was overjoyed, distorted, and a smile appeared on his pale face, which looked extremely weird.

At this moment, Qin Deng felt as if his divine sense had reached the limit, he didn't dare to give up, and he couldn't give up, gritted his teeth bitterly and persevered, seeing hope, he didn't care about it.

Half an hour after "Boom ......", a faint voice from the outside world came from Qin Deng's mind, and the Nine Hells Grass finally fused perfectly with the other spirit grass essences.

"Boom...... Rumble!" A violent bang sounded in Qin Deng's ears, and the entire secret room began to shake violently. There was even a strange aura that entered the secret room, making Qin Deng almost shake his hand and refine and abolish the spirit grass essence that had been fused.

"Dan Tribulation!" Qin Deng's face changed, and he immediately guessed the reason for this abnormality.

The Dan Tribulation is the tribulation of the pill and the tribulation of the Dan Master, and the Dan Tribulation is a reaction to the rules of heaven and earth, indicating that the Night Star Pill refined by Qin Lantern is too against the sky, touching the rules of heaven and earth, and leading to the Dan Tribulation.

The rules of heaven and earth will bring down all kinds of interference, not allowing the pill to take shape, and not allowing the Dan Master to continue alchemy.

"Boom!" There was a loud bang again, and cobweb-like cracks began to appear on the walls of the secret room, according to this situation, it won't be long before the entire secret room will collapse, and when the time comes, the earth will be buried, and the lake water will pour in, and this furnace Night Star Pill will definitely be scrapped.

At this time, Qin Deng's heart also appeared abnormal, he felt that his mind was always unable to concentrate, and the spirit grass essence that had just been completed by Hedan became unstable, which made Qin Deng unable to carry out the last step-Ladan for a long time.

At the moment when Qin Deng Hedan succeeded, Murong San above the lake suddenly smelled a refreshing fragrance, and he felt refreshed. However, before he could wake up from this wonderful feeling, countless fish on the surface of Ming Lake surfaced and began to jump and churn on the surface of the water.

Immediately afterward, the roars of countless beasts began to be heard from the mountains on both sides of Ming Lake. Then on the surface of the lake, the sky for a hundred miles darkened, and a cloud of colorful clouds appeared in the sky.

Soon the multicolored clouds began to spin, and the fragrance above the entire lake became more and more intense. The clouds spun faster and faster, and with a final thunderclap, a thick bolt of lightning rushed into the lake, stirring up the entire lake of Ming Lake.

The waves rolled and the lake shook like an earthquake.

"What's going on?" the three Immortal Star Sect disciples closest to Murong San rushed over and asked in horror.

"This ...... This is the Dan Tribulation!" Murong San exclaimed in shock.

"This is the Dan Tribulation, this is definitely the Dan Tribulation, once there was a similar scene when the uncle was refining the Dan, and the guide fell short in the end. But if you survive and survive the Dan Tribulation, then this elixir refined will definitely have a miraculous effect and be extremely precious. Murong Sanxun said.

"Dan Tribulation, how could Dan Tribulation appear in the sky above Ming Lake?" a thin Immortal Star Sect monk muttered.

"Yes, how could the Dan Tribulation appear here, it is rare for the Dan Tribulation to occur, it is almost impossible for the Jin Dan Master to refine the pill to trigger the Dan Tribulation, only when the Infant Dan Master refines some rare and precious Yuan Infant Grade Spirit Pills, there will be a Dan Tribulation in very few cases. Another Immortal Star Sect monk was equally puzzled.

"Dan Tribulation, Dan Tribulation, is it ...... Could it be that Ding Yan?" Murong San looked at the changes in the entire heaven and earth, as if he was stunned, and his lips kept trembling and opening and closing.

Ding Yan ...... Ding Yan! It's Ding Yan, it's Ding Yan!" Murong San exclaimed, and then quickly threw out a few communication jade slips, and the communication jade slips disappeared into the air and disappeared immediately.

"Give me to keep this lake firmly, this Dan Tribulation only has an effect on the Spirit Pill and the Dan Master, and it has no effect on us. Pay close attention to the situation on the surface of the lake, and if someone rushes out, attack immediately!" Murong Sanwei shouted and shouted loudly.

The changes in the vision of heaven and earth became more and more drastic, more and more terrifying, the entire lake blew a violent wind, and the lake water above the Qin Lantern secret room began to shake slowly, and finally spun, and a huge whirlpool appeared in an instant. (To be continued!)
