Dou Po Zhi from humble beginnings to Dou Di

This amazing devouring power not only did not weaken over time, but became even more terrifying.

Later, the rich fire energy gathered together and, guided by some sparks, was ignited, forming a huge fire energy storm that roared madly above the sky, and was finally swallowed up by the fire cauldron.

The mottled energy that enters the fire cauldron will be tempered into pure and docile energy by the extremely violent flames, and finally flow into the dark gray pill the size of a pigeon egg inside!

As for Lin Feng, facing the endless influx of energy from heaven and earth, he did not dare to be careless. After letting Xiao Ling temper it, he used his soul power to carefully guide the extremely pure energies into the pill.

Throughout the whole process, Lin Feng was extremely cautious, fearing that one careless move would result in the cauldron exploding and the pill being destroyed.

At the same time, he also had to keep an eye on the stability inside the pill. After all, the influx of these energies from heaven and earth could easily disrupt the original balance of the pill, causing it to explode directly.

Therefore, Lin Feng, who was trying to use the energy of heaven and earth to make medicine for the first time, did not dare to be careless.

"This is... My husband is going to improve the quality of the pill as much as possible and try to upgrade it to a treasure pill. However, using this method, even if this treasure pill is finally upgraded to the level of a mysterious pill, it cannot be compared with a genuine ninth-grade mysterious pill. After all, the quality of the medicinal materials used to refine this ninth-grade treasure pill is too different from that of a genuine mysterious pill."

Yun Yun, who was far away, saw this scene and after thinking for a short while, she guessed Lin Feng's thoughts.

After all, now that she has the support of a large number of classic books at home, her vision has changed a lot, so she naturally won't be as ignorant as she was before.

However, seeing such a terrifying sound of alchemy, Yun Yun couldn't help but be secretly shocked.

Generally speaking, when alchemists are refining pills, they will try their best to avoid the energy of heaven and earth from entering the medicine cauldron, because these mottled, unrefined energies will disrupt the balance of medicinal properties between various herbs, thus causing the failure of alchemy.

However, this ninth-grade mysterious elixir is different from other elixirs. Since the energy required is too terrifying, even some eight-star or even nine-star early-stage Dou Sheng will not use all of their body's reserve energy to fill it when refining it, but will give priority to using the external energy of heaven and earth.

After all, they are all using their own energy, so a lot of their own energy will be consumed when refining pills, which will lead to a decrease in combat effectiveness.

At this time, if your enemies come to you, or if some people with bad intentions find your medicine refining place and attack you for various reasons, you will suffer a great loss because your strength has been greatly reduced.

"However, the energy in this demon fire space is several times more dense than that in normal areas outside. In addition, the Pure Lotus Demon Fire has been dealt with, so there is no need to worry about the energy of heaven and earth being tampered with, which would lead to some unexpected situations. If my husband tries to upgrade the pill here, it may not be impossible to succeed."

Yun Yun looked at the majestic energy in the demon fire space and was pulled into the fire cauldron in front of her man. A hint of anticipation appeared on her pretty face.

She also wanted to know whether her man could refine the ninth-grade Xuandan this time.

"Humph, that villain still wants to upgrade the ninth-grade precious pill to the mysterious pill level. I see that the medicinal properties of this ninth-grade precious pill will be destroyed by him, and in the end, he will get nothing!"

When Gu Xun'er saw this scene, she was so jealous that her teeth were almost broken.

Her brother Xiao Yan worked so hard, but in the end he had difficulty refining a ninth-grade precious pill due to the lack of medicinal materials.

But Lin Feng was obviously of humble origin, yet he was able to take out the medicinal materials for two top-grade ninth-grade treasure pills without blinking an eye. Just thinking about it made her feel extremely unwilling for her brother Xiao Yan.

"Damn it, it's all the fault of those old guys in the clan. If it weren't for them causing trouble, how could Brother Xiao Yan's alchemy skills stagnate due to the lack of medicinal materials for the ninth-grade precious pill!"

Thinking about how her brother Xiao Yan's success rate in refining ninth-grade precious pills was not high, but that Lin Feng was able to refine two precious pills in one breath without a single failure, Gu Xun'er wanted to go up and snatch all the herbs in Lin Feng's hands and give them to her brother Xiao Yan.

"If you keep yelling, I'll chop these two little things of yours off with my sword."

Yun Yun, who was standing by, saw Gu Xun'er mocking her man, and then she clenched her jade hands, and a green energy sword quickly took shape in her hand. Then she raised the tip of the sword slightly and placed it in front of Gu Xun'er.

"you"

The latter felt the sharp edge coming from her skin, and her eyebrows immediately stood up. She looked at the vicious woman beside her with a dark face.

Ever since she woke up more than a month ago, she has been using both soft and hard tactics to get Yun Yun to let her go.

But this shameless woman, no one knew where she learned all these tricks to deal with women, and every time she had no choice but to succumb to her opponent's tricks with shame and anger on her face.

Those various "cruel" torture methods made her life worse than death.

Whenever she thought of this, Gu Xun'er wished she could use all those methods on the other party one by one and return all the grievances to the other party!

However, if Yun Yun knew what Gu Xun'er was thinking, she would probably just laugh it off.

After all, she is already a four-star Douluo now. If she gets more resources later, she might be able to jump directly to five stars.

Gu Xun'er is a two-star Douluo, so she is not afraid even if you possess the Golden Emperor Burning Sky Flame, which is ranked fourth on the strange fire rankings.

Because the gap between each star of the Fighting Saint is so huge.

It is so big that even the top geniuses of ancient races find it difficult to kill enemies across multiple star levels.

Moreover, she herself also possesses a treasure with a fast growth rate, such as the Ninth Rank Sky Phoenix Bone Wings, plus powerful soul power.

If a fight really breaks out, even a five-star fighting saint may not be able to survive 100%.

Therefore, the threat of a two-star Dou Sheng was like nothing to Yun Yun, a four-star Dou Sheng.

However, Gu Xun'er made her feel distressed in another way.

Because as time goes by, Gu Xun'er's tolerance for her torturous tricks has greatly increased.

Seeing that the other party's methods were gradually becoming ineffective, the former began to become arrogant again.

This also caused Yun Yun to start changing her tactics and use the methods Lin Feng had mentioned to deal with the other party.

But you know what, Gu Xun'er is really afraid of these tricks.

After all, in her heart, she would definitely be with her brother Xiao Yan in the future, so she was naturally afraid that Yun Yun would really take action, and in the end she would end up losing everything.

However, Gu Xun'er thought again about the dead woman in front of her who had sealed her fighting spirit, and she even threatened her in various ways. Gu Xun'er secretly swore in her heart.

When she gets out next time, I will strip her naked and tie her up at the entrance of the space wormhole in the central square of the Ancient Holy City, to make her angry to death!

However, Yun Yun naturally didn't know what the other party was thinking.

After seeing that Gu Xun'er had calmed down, she immediately put away the rapier in her hand and turned her gaze back to the fire cauldron in the distant sky.

There, as the suction force from the golden fire cauldron continued to be released, the rich energy from the demon fire space was being madly poured into the fire cauldron that was hundreds of feet tall.

And this strange phenomenon seemed to never stop. This crazy behavior of absorbing the energy of heaven and earth in the demon fire space lasted for nearly three days.

During these three days, Yun Yun and Gu Xun'er had no idea how much of the free energy in the demon fire space had been absorbed by Lin Feng.

But the only thing they could perceive was that the energy of heaven and earth contained in the surrounding air had become more than 60% to 70% thinner than before!

As for this scene, both of them couldn't help but show a look of shock on their faces.

I'm afraid that even the body of a four-star Douluo cannot contain this much energy.

However, who could have imagined that the energy that even a four-star Douluo could not contain could be used to refine a pill the size of a pigeon egg, and it would actually be completely consumed!

This kind of grand occasion was the first time even for Gu Xun'er to see it today.

Although there is an elder in their ancient clan who can refine the ninth-grade Xuandan.

But according to what those old men said, the success rate is only about 20% to 30%. Unless someone is in urgent need and this person has great potential, the clan will not approve the application for the medicinal materials needed to refine the ninth-grade Xuandan.

After all, those medicinal herbs are extremely precious even for their ancient clan, and they must be used with the best steel!

Ordinary people, including the three immortals of the ancient clan who ranked third in their clan, also did not ask the elders to approve the transfer of medicinal materials and let the elder refine the ninth-grade Xuandan for the three of them.

"Ancient books say that even in the ancient times, wherever a ninth-grade Xuandan was born, the space within a thousand miles would be barren, with no grass growing, because all the energy of this world was absorbed into the elixir. Now it seems to be true!"

Yun Yun stretched out her hand and clenched it lightly, sensing the rare energy of heaven and earth in the air around her, and couldn't help but exclaimed in amazement.

But then again, the ninth-grade Xuandan can be considered a man-made divine object, and the energy required for its formation is terrifying enough to shock many Dousheng powerful men.

Even when taking it, if you are not a high-level Dou Sheng of the seven-star level, you still have to make many preparations before you dare to swallow it. Otherwise, you will surely end up exploding and dying.

Even the magical beasts known for their strong physiques need to reach at least the middle six-star realm or above before they dare to be swallowed directly.

Otherwise, the terrifyingly dense energy in the ninth-grade Xuandan would burst his body with a bang.

"Humph, this bastard will definitely explode the cauldron in the end. It would be best to blow him up directly to save Brother Xiao Yan from being depressed every day."

When Gu Xun'er saw this scene, she immediately started cursing in her heart.

After all, she didn't have the slightest fondness for Lin Feng. All she had was overflowing malice!

However, things did not go as planned. No matter what Gu Xun'er thought, the huge fire cauldron in the sky showed no intention of exploding. Instead, as the nearly endless energy of heaven and earth poured into it, it became brighter and brighter.

At the same time, Lin Feng sensed the dark grey pill in the center of the fire cauldron. The fluctuations it emitted were gradually getting stronger, and the corners of his mouth couldn't help but rise slightly.

At this point, even if the elixir he refined this time could not reach the level of Xuandan, it would definitely not end up with the cauldron exploding.

This suction force of the fire cauldron in front of Lin Feng continued for a few days, and the energy of heaven and earth in the demon fire space had been almost completely absorbed.

Even the magma below has become much thinner at this moment because it can no longer absorb energy from heaven and earth.

After all, this milky white magma is not normal magma at all, but an energy reserve created by the Pure Lotus Demon Fire, which provides him with sufficient energy support when he performs the Ancient Heaven Refining Formation.

Although a lot of this energy had been consumed by the Pure Lotus Demonic Fire in the previous formation, the remaining amount should not be underestimated.

But now, a small half of it has been absorbed.

As for the others, since Lin Feng could not completely control the demon fire space and could not easily separate the energy from the magma, he could only give up for the time being.
