Although it is not easy to improve between the same level of the inner grade and the grade, as long as you work hard and keep up with the power of your soul, it is not as difficult as you imagine. The difficulty is the improvement between the grades, such as from ordinary ninth grade to the emperor, from the yellow grade of the third grade to the fourth grade of the emperor, from the mysterious grade of the fifth grade of the emperor to the ground grade of the sixth grade, from the earth grade of the seventh grade of the emperor to the heavenly grade of the eighth grade of the emperor; and there is no one in the ninth grade of the emperor, there is currently no Doudi Continent in Doudi Continent, and everyone only knows how many of them were before the ancient catastrophe; as for the dark-level alchemist who surpasses the ninth grade of the emperor, the Doudi Continent has never heard of since ancient times, but there is only the saying of this level in ancient books.

Xiao Yan is now going to break through from the sixth level of the Earth level to the seventh level of the same level. With his powerful Heavenly Fire and the soul power of the late Yi level, it is indeed not difficult.

Looking at Long Yi, who was sitting cross-legged in a corner, sucking thunder, lightning flashing all over his body, and the fluctuations of the breath and fighting spirit were slowly increasing, Xiao Yan took out the prescription given by the old Demon Emperor and took out two seventh grade pieces.

There are only two seventh grade prescriptions given by the Old Demon Emperor, namely-

Shenfu Dan: Increases the recovery speed of Dou Qi by four times.

Explosive Pill: The effect is the same as Huntian Pill. After taking it, the strength has been greatly improved during the efficacy period, but the sequelae is great. After the efficacy of the medicine, it weakens for an hour and its strength has dropped to one fifth of the usual one.

This is not the first time I have seen these two prescriptions, but there is still a hot light in Xiao Yan's eyes, lamenting that it is worthy of being the prescription collected by the Old Demon Emperor, and the effect is indeed amazing.

Although the Shenfu Dan is one grade higher than the Speed ​​Return Pill, the magical effect of four times the Speed ​​Return Pill is far more than the first grade. It is not an exaggeration to call it a life-saving magic medicine in an emergency.

The explosive power pill is a substitute for the Huntian Pill exclusively for high-level Doudi. After all, the Huntian Pill is too low and it is quite effective against Doudi below five stars, but the effect is no longer obvious for Doudi above five stars, especially for Doudi above six stars. In the bloody battle between more than a dozen Doudi, such as the Fifth Ring Qilin Mountain and Lan Yang, Xiao Yan, if he had this explosive power pill, he might not be able to defeat Lan Yang, etc., but Xiao Yan was confident that he could kill only Lan Yang, the only one left in the Dan Hall!

But Xiao Yan's eyes kept twitching when they were hot, because the medicinal materials needed to refine these two magical seventh-grade pills were really amazing - not only does it require three life fruits to refine a Shenfu pill, but also one seventh-grade magic core with water and wood attributes! In addition to refining a explosive pill, it also requires a seventh-grade medicinal material Thunder Pill and fire attributes, and one metal magic core!

Not to mention anything else, the seventh-grade magic core alone is not affordable by ordinary people, and it is difficult to acquire it on the market. If Zhen Ni had not started to acquire it long ago - after all, whether it is used to refine medicine or Xiao Yan to absorb and improve the level, the higher level magic core is better - Xiao Yan would never be so confident that he would break through to the seventh-grade this time.

‘Old Demon Emperor, the two seventh grade prescriptions you have treasured are about to regain the glory of the past.”

Xiao Yan took a deep breath, and with a thought, the medicinal materials flew out of the ring and were divided into two piles of them in the air in front of the left and right of the Yanmu Ding.

‘Refining the explosive power pill first.”

His fingers were picked out from the air, and he emitted two Dou Qi to wrap a medicinal material that refined the explosive power pill into the Yanmu Cauldron. The flames in the cauldron suddenly jumped up, refining the medicinal material into a ball of medicinal liquid...

But when all the medicinal liquids of the medicinal materials merged together, a "bang" sounded in the cauldron.

Looking at the charred black in the cauldron, Xiao Yan shook his head and reflected: 'It is much harder to refine seventh grade pills than to refine sixth grade. Just now, the soul power was not released stably enough, and it failed."

After summarizing the experience, Xiao Yan calmed down and started the second refining.

'Bang!"

'Bang!"

'Bang!"

However, the explosion of refining failed would sound in the pharmacy every once in a while. Long Yi, who had absorbed the thunder, sat in the corner and watched nervously, waiting, heartbroken, quietly, afraid of disturbing Xiao Yan.

Finally, after four failures, for the fifth time, Xiao Yan's face gradually changed from ashen to gentleness and then appeared in joy. A Explosion Pill with yellow and yellow in red was formed, and the room was filled with its strong fragrance of medicine.

‘Congratulations to Daddy for breaking to the seventh grade!’ Long Yi laughed and got up, walked out of the pharmacy and pulled up, and faced the roaring seventh grade thunder.

The seventh-grade elixir is far from comparable to the sixth-grade elixir, but it was swallowed by Long Yi, who transformed into the Nine Profound Golden Thunder Dragon in two or three mouths.

Seeing Long Yi falling from the sky with joy, he immediately sat down cross-legged to absorb it. Xiao Yan put the explosive power pill into a jade bottle, his eyes stayed on the two piles of medicinal materials suspended there. His heartache for the medicinal materials was not diluted by the joy of breaking through. The corners of his eyes couldn't help but twitched a few times, hesitating: 'It took five mats to succeed one, and the success rate was not average! Should I continue to refine it?"

Looking at Long Yi who absorbed the thunder, he thought of the importance of the two elixirs to the core team, so he decided to continue to refine the two piles of medicinal materials.

‘I don’t believe that the success rate will always be so low!”

A bunch of sky fire once again jumped in the Yanmu Ding, and one medicinal herb after another turned into balls of medicinal liquid...

Like practicing medicine, there is no concept of time. When the medicinal materials in the air in front of the Yanmu Ding are empty, I don’t know how many days and nights have passed.

‘Although the failure rate has been reduced a lot, it is still as high as 30%!’ Xiao Yan was heartbroken with the waste of refining the medicinal materials. He held a bottle of jade bottles containing the Shenfu Pill and the Explosion Pill in one hand. He sighed in his heart that he was really burning money by refining these seventh grade pills.

‘Ten Shenfu Danshe, well, Muer, Long Yi, Xiao Zhan, Nan Erming, Storm, and Ziying, and there are four left. Let’s give one for the elder brother and the fourth elder. I will leave two for myself; the seven explosive Danshes are just right for Muer, Long Yi, Xiao Zhan, Nan Erming, Storm, Ziying and I one by one. ‘Thinking in my heart, seeing Long Yi who had swallowed the thunder, swept in, he took out one of the explosion Danshes and shot it to Long Yi with his fingers, ‘Long Yi, these two are yours.’ Then he put away the two jade bottles and asked Long Yi a smile, ‘How does the seventh-grade thunder taste?”

Long Yi's golden eyes suddenly flashed with a light of joy, 'It's much stronger than the sixth-grade ones.' Then he said with a burning look, 'Dad, maybe I'll be promoted to the peak of the sixth-grade thunder before I absorbed these seventeen seventh-grade thunders, and I may surpass you."

‘Hahaha! It’s good to surpass me!’ Xiao Yan laughed, ‘The stronger you are, the happier I am. I wish you were better than me.”

Xiao Yan did not tell Long Yi that there were very likely two heavenly fires in the jade box he opened after breaking through to the peak of the six-star. He reminded him, "Then you should absorb it slowly here." He hurriedly said goodbye to Long Yi and rushed to the practice room to absorb the magic core.
