The wind, blowing gently, shook the different shades of green all over the mountain, and the cave inside the mountain peak was quiet.

The perspective glanced in this seemingly random cave mansion, passed through the room where the exercises and magic weapons were placed, passed through the elixir circle full of vitality and medicinal fragrance, and also saw the lucky general who was sleeping soundly, and the wolf cub who seemed a little bored and grinding his teeth.

Bypassing these, the gaze continued to scan forward along the not-so-bright passage, and through the not-so-long passage, a golden-red firelight could be vaguely seen, and the sound of thunderclaps could be faintly heard from time to time.

When I got closer, I saw that Mo Qing, dressed in green clothes, was sitting cross-legged on the ground, holding the seal in his hand expressionlessly.

Half a foot high in front of him, a golden-red flame rose from the red black essence fire, wrapping a jet-black bamboo the thickness of a baby's arm, constantly refining.

And on the surface of the ink-black bamboo, there is a layer of black streamer clinging to it, and if it weren't for the thunderclap sound that sounded from time to time, it would be difficult for people to associate the black streamer with thunder and lightning.

This black bamboo is the Zhiyin Thunder Bamboo that Mo Qing got before, no one has arrived, it was not a very inconspicuous thing back then, but it has such a big origin.

From time to time, Mo Qing opened his mouth and spewed out a black and white flame to join the refining of the Yin Thunder Bamboo, this flame was his Dan Fire.

It's just that this Yin Thunder Bamboo is really a little too difficult, and it has been continuously burned with the Red Black Essence Fire and Dan Fire for more than a month, and there is no trace of melting so far.

However, it is not without the slightest progress, at least the Zhiyin Divine Thunder, which was originally released with about three inches, is now suppressed and tightly attached to the Zhiyin Thunder Bamboo.

As long as it continues to be burned in this way, it will be refined one day......

Seeing that the Dan Flame that he had spewed out was extinguished again, Mo Qing freed his hand and pointed at a place not far from him, and a black and white spiritual light flew out from his fingertips, wrapping a small bright brown particle that was placed there with the lid open, and evenly falling on the Red Black Essence Fire.

With the addition of these things, the red black essence fire shook violently, and with a loud sound, it directly rose more than a foot high, and the scorching temperature rushed to the face, drumming in all directions.

This situation didn't go out for long, and suddenly there was a 'poof' sound from the raging flames, and the layer of Yin Divine Thunder that covered the Supreme Yin Thunder Bamboo finally dispersed.

Mo Qing's face was overjoyed, and he couldn't help but sit up straight, cheer up, and then continue to refine the Yin Thunder Bamboo.

Once the Yin Divine Thunder outside is dispersed, the remaining Yin Thunder Bamboo body is too much to do.

Although it is still extremely tough, it also does not last long in front of the ultra-high temperature of the Red Black Essence Fire.

It's just that after a day's time, the Yin Thunder Bamboo has already shown signs of melting.

Time passed little by little, and the fire in the room never dissipated, and the figure in green clothes always sat there and did not move.

Although the continuous output had already exhausted him, he did not stop the movements in his hands.

The Red Black Essence Fire continued to burn, and the Yin Thunder Bamboo wrapped in it had completely melted and turned into a mass of black liquid.

As the red black essence fire continues to burn, some impurities will be separated from time to time, bursting into a bright flame, and then disappearing......

Seeing that the impurities in the Yin Thunder Bamboo had finally been thoroughly refined, Mo Qing, who had already been exhausted, waved his hand and recalled the Red Black Essence Fire that had been burning continuously for half a year.

Then he put the fist-sized Yin Thunder Bamboo Essence in front of him, watched it carefully for a while, and then separated a flame from the Red Black Essence Fire and wrapped it, and then put it into a purple gold bottle, and added three or four layers of seals on the outside, which can be regarded as a relief.

It also makes sense for Mo Qing to do this, if he doesn't use the Red Black Essence Fire to wrap the seal, then the essence of this Yin Thunder Bamboo will solidify in a short period of time, and it will take a lot of effort to refine it when the time comes.

After everything was done, the exhausted Mo Qing let out a long breath, found some water and wiped his face indiscriminately, ate some things casually, and came to the bed that had been made a long time ago, and fell asleep at the end of the day...... He slept for five or six days before he returned his soul.

After a short rest, Mo Qing began to sit and cultivate non-stop again.

After more than ten days, Mo Qing, who had returned to his peak state, sat down cross-legged again, releasing a large number of materials......

Because of the experience of refining to the Yin Thunder Bamboo, when he started refining the Thunder Stone, Mo Qing became much more proficient.

Although the Thunder Stone is also difficult to deal with, it can't resist Mo Qing's perseverance in refining it, and after about half a year, Mo Qing became exhausted again, and the Thunder Stone was finally completely refined by him......

After a full rest, Mo Qing sat down cross-legged again, he didn't rush to start moving, but closed his eyes, carefully recalled, every detail in the refining, until he was sure that everything was memorized and mastered, he didn't open his eyes.

didn't speak, but waved his hand to take out the bottle that sealed the thunder stone and opened it, and with a light movement of his palm, a small stream of red black essence fire wrapped in the essence of the thunder stone flew out.

At the same time, the body of the Red Black Essence Fire hidden in its right arm also flew out, and with a slight twist, the wisps of Red Black Essence Fire that separated from it merged with it, burning around the essence of the Thunder Stone.

As the flames rose, Mo Qing pointed at his side, and a white porcelain bottle flew out of the many materials, tilting towards the thunderstone essence that kept writhing in the ball.

The gray-brown powder was evenly sprinkled, and the color of the Thunderstone Essence changed in an instant, and there was also a faint flickering of thunder in it.

Mo Qing spewed out a Dan fire, helping the Red Black Essence Fire to incinerate the essence, because the material just added required an extremely high temperature to completely fuse with the Thunderstone Essence!

If it is delayed for a long time, it will not only affect the quality of Yin and Yang Shuangshuang, but even worse, it may also destroy the thunder stone that he obtained at the risk of his life.

His spirit was highly nervous, he paid attention to the heat, did not dare to make the slightest mistake, and from time to time waved his hand to add various materials to it.

This kind of work lasted for nearly a month, and nearly half of the many materials on the ground disappeared, and Mo Qing finally stopped the movement in his hand, and looked at the white viscous liquid without a trace of impurities wrapped in red black essence fire in front of him with a happy face......
