The white light flickered and flickered, becoming more and more dazzling.

The refining method of this thousand heavy pills is not difficult, it does not require real fire calcination, nor does it require the use of a ding furnace, and it does not even take long to take time.

The length of time required to refine often means the difficulty of refining, and the shorter the time required for the elixir, it usually means that it is easier to refine, not too difficult, and vice versa.

The only thing that made Chen Zhi smack his tongue was that the medicinal materials for refining this Thousand Heavy Pill were really not so easy to obtain, but fortunately, he met two formation mages who were extremely obsessed with the formation, so he had the opportunity to obtain the two flavors of the Thousand Heavy Pill from the two of them.

Chen Zhi didn't know how many times he had seen the refining method of this thousand heavy pills, so although it was the first time to refine it, he looked quite experienced.

At this moment, after reciting the method of refining this elixir in his heart, he began the formal refining.

The hand pinched the law, and shot out eight blue lights in a row on the white light, and the white light seemed to feel a burst of streamer operation, absorbing these red lights, and then the surface of the white light gradually dimmed, showing a cluster of black light, as soon as the black light appeared, a ball of purple flames the thickness of chopsticks erupted from it, wrapping the white light in it. Suddenly, the whole room was shrouded in a cloud of purple light, and seeing this, Chen Zhi was also secretly surprised.

However, because the melon that was memorized by this refining method was ripe, he did not hesitate to point his fingers and send out several methods to decide.

As soon as these spells hit the white light, they suddenly became as thick as silk threads, and then disappeared into the white light in a flash, disappearing without a trace.

Chen Zhi ignored this, his fingers flicked one after another, and several magic decisions flew into the white light.

But no matter how many Dao Dharma Decisions flew into, the white light only flickered slightly, and it absorbed all of these Dharma Decisions without hesitation, but there was not much change in itself, only that the light converged a little.

In this way, the mana in Chen Zhi's body quickly dried up like water in a pool that had been pumped away, but fortunately, Chen Zhi had already prepared, reached out and touched the treasure bag, put a pill in his mouth, and then took out a piece of spiritual jade, held it in his hand and began to slowly absorb the pure spiritual power inside.

Under the dual effect of the elixir and spirit jade that replenished mana, Chen Zhi finally sent out several magic decisions one after another, and the white light finally made some changes.

The purple fire that was originally wrapped in the white light, after the white light absorbed so many magic decisions, Chen Zhi finally felt that they began to obey his control, although there was only a little bit of control, but it finally showed that it was not in vain for so many magic decisions to enter the white light.

As he was able to control the circulation of those purple fires, Chen Zhi's magic decisions into the white light became less and less, but the effect was better than when he entered so many magic decisions before, and this change made Chen Zhi surprise and abnormal. People have changed a lot of spirits all of a sudden.

As time passed, a trace of medicinal fragrance emanated from the white light, which made people feel refreshed after smelling it, but Chen Zhi, who had learned some Qihuang Zhishu fur in Guangyuan Temple, also knew that it was still early for Cheng Dan at this time, because the heat required by Cheng Dan was extremely strong, at least it was necessary to use a more violent flame to rise to a very high temperature in an instant, and these raw materials could be condensed into Dan.

Thinking of this, Chen Zhi took out another pill and swallowed it, and then played several methods one after another, feeling that all those purple fires were under his control, and finally started the last step of the Ning Dan.

After controlling these purple flames and gradually stabilizing down, Chen Zhi also began to slowly adjust his breathing, slowly gathering mana in the palm of his hand.

After a little hesitation, Chen Zhi still slapped out with one palm, and a purple-blue magic law the size of a bowl shot straight into the white light, and the purple fire that had been stable seemed to sense something after the law shot into the white light, and suddenly the light burst into flames.

Within the white light wrapped in purple fire, a dark green light the size of a fingernail appeared, but after only a flash, it was shrouded in white light again and disappeared.

Despite this, in the wrapped white light, there are still bursts of strange fragrances constantly wafting out, which makes people feel relaxed and happy when they smell it.

As the initiator, Chen Zhi naturally knew that this was the vision of the beginning of Ning Dan.

After carefully controlling those purple fires and condensing the heat together, these purple fires also became as thick as the mouth of a bowl, and the white light completely turned into a huge fireball, and with the light of the purple light, the medicinal fragrance became more and more intense.

"Sneer, sneer......"

A strange sound continued to sound from the purple fireball, but Chen Zhi sat on the ground with his head bowed and his eyes closed, his hands pinched again and again, beads of sweat the size of beans continued to emerge on his forehead, green tendons bulged, and white mist in his nostrils continued to expand and contract, as if he was enduring great pain.

But even so, he still didn't dare to slack off and constantly change the law in his hand, and the purple fire became more and more dazzling.

Finally, in the purple fireball, a crisp and abnormal "ding!" sounded, and then, after a violent flicker, the purple fire suddenly turned into nothingness, revealing a white ball of light that was originally wrapped in purple fire.

As soon as the white ball of light emerged from the purple fire, it shattered like porcelain and dissipated into the air with a bits of white light.

Then a fist-sized green light flashed out in the white light, as soon as the white light dissipated, the green light also shone brightly, and Chen Zhi finally saw clearly, it was a jade green pill, the surface was as bright as jade, like the size of a dragon's eye, and there was a strong medicinal fragrance all over the body.

"It worked!"

You don't have to guess Chen Zhi to know that this is a scene only in Cheng Dan, this turquoise pill is the body forging elixir "Thousand Heavy Pill" that has always been dreamed of.

After stretching out his hand a little, the emerald green pill fell into Chen Zhi's hand at once, and he impatiently put it in his mouth, just about to refine the medicinal power in it, Chen Zhi suddenly felt that something was wrong.

Why did the temperature in the stone chamber drop so much all of a sudden? Although the purple flame was extinguished, it stands to reason that the temperature shouldn't have dropped so quickly?

Thinking of this, Chen Zhi raised his head, and when he saw it, he was startled by the situation in the stone room.

Probably because he was too focused on refining the elixir, he didn't even notice that the scenery in the stone room at this time had changed drastically!

At this time, in the stone room, I don't know when the road has become dim, except for the place where the original white light is still barely retaining this trace of heat, the other places are a little gloomy, everywhere there are clusters of black air balls flying around, and there are countless cold yin qi, emanating from the stone room.

The three flying centipedes had disappeared at this time, but in their place, in the four corners of the stone room, three corners were shining with blue light, and there was an oval-shaped cocoon-like thing, on which a faint cyan halo emitted, and as soon as the halo was collected and released, countless cold qi diffused from the cocoon, filling the entire space at once.

Chen Zhi, who had just finished taking the "Thousand Heavy Pills" and had not yet completely refined the medicinal power of this elixir for his own use, was rushed by this cold qi, and suddenly shuddered, and couldn't help but be a little surprised, when did these changes start?

Due to the reason of being too focused, Chen Zhi didn't know what happened to Lu Dao when he was refining the elixir, so he had to slowly recall some of the things just now.

After thinking about it for a while, Chen Zhi suddenly came to his senses, and combined with the fact that the three centipedes were missing, he suddenly understood, could these centipedes be among the three light cocoons?

And looking at the appearance of those light cocoons, it seems that something is pregnant.

After thinking about it, Chen Zhi still left the stone room, but he found a place outside the stone room, sat down cross-legged, and while meditating, he carefully paid attention to the situation in the stone room with his spiritual sense.

When Chen Zhi was a child, he once raised some silkworms, and when he knew that these silkworms evolved, as a breeder, he could not intervene in them, although he didn't know if these centipedes were the same as spirit beasts, but as the owner, he still sat down outside the stone with great confidence.

Time passed minute by minute, but those light cocoons did not change too obviously, which made Chen Zhi a little impatient, but when he encountered this matter for the first time, he really didn't have any good way, so he could only slowly refine the medicinal power of the Thousand Heavy Pills while playing the role of a guardian for the evolution of these flying centipedes.

But what Chen Zhi didn't expect was that the medicinal power of this Thousand Heavy Pill was too domineering, and it continued to impact his internal organs and meridians all over his body.

The medicinal power emitted by the turquoise pill left in his abdomen began to surge towards the meridians all over his body, and what Chen Zhi didn't expect was that these medicinal powers not only operated in the meridians, but even wrapped through the meridians into the bones and muscles of the whole body.

When the muscles and bones of the whole body were just wrapped in these medicinal powers, they originally felt warm and comfortable, but it didn't take long for the heat contained in the medicinal power to begin to be continuously released, and they began to burn the body continuously, and the heat that lingered in the meridians even began to rush towards the brain because there was nowhere to vent.

Just when Chen Zhi was a little headached by the impact of the heat that had nowhere to vent, and he was lying on the ground unable to move, the mana in his body suddenly started to work on his own, and these mana rushed into Chen Zhi's eyes on their own, after being affected by this, Chen Zhi's eyes flashed blue, and a cold air flow began to flow slowly from his brain to the lower part of the body.

Like a scorching flame being hit by cold water, these vigorous heat finally began to calm down, and began to flow slowly towards Chen Zhi's body under the guidance of the cold air.
