After Chu Cheng agreed to Chen Yin's alliance, he went to the Alchemy Hall again.

Now that the fifteenth layer of qi is gathered, refining the Hui Qi Pill is a breeze, and in just three days, seven furnaces have been refined in a row.

This made Master Fang Dan also dumbfounded, even if it was him, it would take several days to refine a furnace of finished Qi Returning Pills.

"Unexpectedly, with the improvement of cultivation, it will be easier to refine the pill. Chu Cheng looked at the white pill in his hand and muttered with a smile.

Only then did Chu Cheng know that if he wanted to refine a high-grade pill, cultivation was also very important. According to Chu Cheng today, refining a first-grade pill is very easy!

He took the pill back, put it in the pill bottle, and placed it on the ground.

The floor was lined with a row of blue and white porcelain vases, and if you counted them carefully, there were seventeen bottles.

A furnace of Huiqi Dan has twelve pills, which are six for a bottle, and seven furnaces are fourteen bottles.

Chu Cheng looked at the fourteen bottles of pills and was very satisfied. You must know that one Qi Returning Pill requires two contribution points, and one furnace of twelve is twenty-four contribution points!

He successfully refined these pills, and the sect purchased them with six three contribution points, and earned thirty-six contribution points in just three days!

At the beginning, Chu Cheng had been in Baicao Valley for three years, and he had only received more than 200 points, and what was even more pitiful was Old Man Meng, who spent more than 50 years and only received 200 points!

Chu Cheng stood up and soothed his muscles.

"Alas, it's really boring, although this world is good, not only can you cultivate, but you can also live a hundred years old, and you can live a thousand years old, or even long live, but there are not as many flowers and fun as in the previous life. Chu Cheng sighed.

It's like an entertainment venue, movies, TV, nothing.

It's been four years since I came to this world, but I still haven't fully integrated into life here.

"If people in this world make a fantasy masterpiece, I'm afraid the special effects will be quite good!" Chu Cheng thought to himself at this time. If he can return to Earth, he will definitely be able to mix up an Oscar.

"But if you talk about combat effectiveness, maybe there is something on the earth that can match the power of Jindan, or even the power of Yuanying!" Chu Cheng thought of nuclear weapons at this time, which was enough to destroy the planet.

"Yes! Nuclear weapons!" Chu Cheng suddenly thought of this. Although I don't know the principle of nuclear, I only know that nuclear fission occurs.

But he got an idea from a point!

Chu Cheng took back the fourteen bottles of pills, hurriedly opened the pill ban, and walked out of the house.

"Master Fang, I'll go first!" Chu Cheng shouted at Fang Dan Master and flew in the direction of the teleportation array!

......

The inner gate area is not like the outer gate is a plain, but a high mountain towering, and the inner gate disciples are all opening caves on some mountains. Moreover, the aura in the inner door area is much more abundant than that in the outer door.

Chu Cheng first found the deacon of the inner gate and directly received an uninhabited cave mansion.

This cave house is much larger than the residence of the outer gate, with two bedrooms and a living room, and a cultivation room.

It was a bit empty to live with only one person, and the deacon had told Chu Cheng that the inner disciple could bring an attendant to serve, and this news made him happy.

He planned to go back to the Yellow Kingdom in a few days, and then bring Ling'er to the Luoyun Sect, and find a way to let her practice.

When Chu Cheng came to the cultivation room, he saw a small formation carved on the wall, and he also knew that it was a small spirit gathering array!

The Spirit Gathering Array is different from the Soul Locking Array, the Spirit Gathering Array is used to absorb the nearby spiritual energy, making the spiritual energy on the mountain peak more intense, and because of this, there are only twelve caves on a mountain peak.

Twelve cave mansions, naturally there are twelve spirit gathering arrays, if there are too many spirit gathering arrays, I am afraid that the spiritual energy within a radius of ten miles will not be enough for the disciples on the mountain peak to cultivate.

Since the cave mansion that Chu Cheng received was located in the most remote place with the inner gate, there were only five disciples living in it, plus him.

This has provided him with a lot of convenience.

After all, if he cultivated, it would be too great to absorb spiritual energy!

Chu Cheng was quite satisfied with this practice room, with an area of more than ten zhang, and a formation carved with it, which was very solid.

Chu Cheng sat down cross-legged and took out three talismans from the storage bag.

A wind, a wood, a fire.

The three talismans were lined up and randomly crushed by Chu Cheng.

The first one to crush was the fire talisman, and as soon as the talisman shattered, a fireball suddenly arose.

With a snap, the second wooden talisman shattered, and wooden arrows were suspended in mid-air.

Chu Cheng waved with one hand, and those wooden arrows flew into the fireball one after another, and as the wooden arrows fused, the fireball burned even more violently.

Immediately after the crack of the wind talisman, a white wind blade slowly approached the side of the fireball under the traction of Chu Cheng, and then dissolved, turning into a layer of wind film, covering the fireball.

The inner layer of wood, the outer layer of wind, and the fireball are burning violently and sizzling.

"The three complements can indeed increase the power of the fireball technique, but it doesn't have much effect. Chu Cheng muttered to himself and was silent for a moment.

After a while, Chu Cheng stretched out a hand, stretched out under the fireball, and bent it slightly.

"Dry firewood!" Chu Cheng snorted softly, and the law was decided.

In the palm of his hand, a cloud of white gas poured into the fireball, and in an instant, the fireball began to boil violently. Wisps of fire splashed, and they turned around in an instant.

After ten breaths, the fireball grew brighter and brighter, like a small but dazzling sun!

At this moment, Chu Cheng's expression became more and more solemn.

"Dry wood and fire, only now did I understand the meaning of these four words. These four words have a deep meaning in the words Chai and Lie. Chu Cheng's eyes flickered, and a fireball like the sun was clearly reflected in his pupils!

Timber is the root of fire, and fire is born with wood. With timber, this fire can burn brightly! And it can be fierce, and only then can the dry wood fire be brought into full play!

Chu Cheng took a deep breath and started the last step!

Although this fire is fierce enough, it is fierce enough, and it is several times more powerful than ordinary fireball magic! But it is still not enough!

At this time, this fireball can only be equivalent to a human-level mid-grade exercise, which still can't cause damage to the monk in battle.

You must know that the spells that monks in the late stage of Qi Gathering generally learn are all of the highest grade in the human level. As for the foundation building monks, they all use the yellow-level exercises!

Like artifacts, the spells released by holding spiritual weapons are more than half as powerful as those released by magic weapons! The same is true for exercises. Like Sword Light and Shadow is just a character intermediate spell, but with the possession of a mid-grade spirit weapon, the power can reach the character level! At least the power is nearly seven layers!

Chu Cheng's expression was serious, he used the spiritual power in his body, and his hands covered the fireball.

"Drink!" Chu Cheng snorted softly, and a strong force poured out of his palm!

At this moment, the fireball trembled in vain, spun up in an instant, and rubbed with the air to create dazzling sparks.

Chu Cheng's eyes didn't blink, staring at this fireball.

Time passed, Chu Cheng's eyes still did not blink, and he kept pinching his hands. I saw that the fireball, which was originally the size of a large head, had become the size of only two fists, but the exposed red light was even more dazzling!

Wisps of sparks, constantly sputtering, stained in Chu Cheng's hands, making a snorting sound and a burst of white smoke.

Chu Cheng didn't cry out in pain, and still pinched his hands.

After a stick of incense, the fireball turned to the size of a fist.

Although it is twice as small, the measurement is several times higher, so dazzling!

The fireball became more violent, crackling and crackling. Inside the fireball, the fires are striking, splitting, and striking!

Zizizi......

The fireball is constantly hitting inside, from fire to fire and as small as molecules.

On the outside, the flames were boiling, and although the violent activity could not be seen inside, with the divine sense, countless molecules could be seen violently hitting each other, and then decomposing again, and hitting again, almost a hundred times in an instant!

As the fireball continued to get smaller, the impact and splitting during the period became faster and faster, and finally reached the previous breath!

"Whew!" Chu Cheng took a deep breath, withdrew his hands, and looked at the fireball that had been compressed into only half a fist by himself. Smile.

"Sure enough, I guessed correctly, the dry firewood fire is not like before, it is just a simple increase in the power of the fireball technique, but a qualitative change in the fire spell!" Chu Cheng muttered with a smile, looking at the small fireball.

Although from the outside, this fireball is only a little smaller and darker than the ordinary fireball technique, but the terrifying aura contained in the period has reached a certain terrifying level!

Although he didn't try the power, Chu Cheng estimated that the power level was at least dozens of times higher than the original one! With the combination of dry wood and fire, this new fireball technique was at least not inferior to Huang Pin's lower-level exercises!

A yellow-level exercise will cost at least more than a thousand contribution points in Luoyun Sect, and it will sell at least a few thousand medium-grade spirit stones in Fenghua City!

As for the yellow-level mid-grade, I'm afraid it will cost hundreds to thousands of high-grade spirit stones!

Chu Cheng was still very satisfied with this experiment, although the power of this fireball technique was not as strong as the Seven Ways of Jumping to the Sky, it was better because it consumed less spiritual power! After all, no one would take an introductory spell seriously.

Suddenly, a destructive force permeated the practice room.

I saw a thin slit crack in the small fireball, and it split along the way.

Click......

Chu Cheng's face changed dramatically in an instant, and a bad feeling instantly surged into his heart, this feeling can usually save his life for a monk!

He stood up immediately, and rushed to the door almost instantly.

Just as he passed through the door, the fireball burst into flames, and then exploded with a loud bang!

Boom Boom!

The earth shook and the mountains shook! The whole cave shook at this time!

"Ahh

Chu Cheng faced the ground, and a white hard object flew out of his mouth.

A rectangular object, spinning in mid-air, with two spikes protruding from the bottom, with a trace of blood.

"I'm dripping mom!" Chu Cheng instantly sensed that something was wrong. At this time, I only felt that my mouth was cold, and the wind entered.

As soon as Chu Cheng touched his mouth, his face changed suddenly, and he saw blood in his mouth, one of the places was empty, and the two front teeth had already disappeared......

He looked down and saw that another front tooth had fallen to the ground.
